The Board of Directors approved these interim financial statements on August 12, 2024.

---

(b)  Use of judgements and estimates:

The preparation of the interim financial statements in conformity with IFRS requires Hudbay to make judgements, estimates and assumptions, in applying accounting policies that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the interim financial statements, as well as reported amounts of revenue and expenses during the reporting period. Actual results may differ from these judgements, estimates and assumptions. The interim financial statements reflect the judgements and estimates outlined by Hudbay in its audited consolidated financial statements for the year ended December 31, 2023.

3. New standards

New standards and interpretations adopted

Amendment to IAS 1 - Presentation of Financial Statements

The amendments to IAS 1 clarify that only covenants with which an entity is required to comply on or before the reporting date affect the classification of a liability as current or non-current. In addition, an entity has to disclose information in the notes that enables users of financial statements to understand the risk that non-current liabilities with covenants could become repayable within twelve months. Classification is unaffected by the expectations that the entity will exercise its right to defer settlement of a liability. Lastly, the amendments clarify that settlement refers to the transfer to the counterparty of cash, equity instruments, other assets. The amendments are effective for annual periods beginning on or after January 1, 2024. The amendments have been adopted by the Company and the amendments did not result in any changes to the interim financial statements.

4. Acquisition of Copper Mountain Mining Corporation

On June 20, 2023, Hudbay acquired all of the issued and outstanding common shares of Copper Mountain Mining Inc. (formerly, Copper Mountain Mining Corp., and referred to herein as "Copper Mountain"), as part of a court-approved plan of arrangement. At the time, Copper Mountain held 75% of CMBC, the entity that owns 100% of the Copper Mountain mine. MMC owns the remaining 25% interest in CMBC as a non-controlling interest.

As a result of the acquisition, Hudbay obtained control of Copper Mountain on June 20, 2023.

Management determined that the assets and processes comprised a business and therefore accounted for the transaction as a business combination, using the acquisition method of accounting.

Consideration transferred:
The purchase consideration paid by Hudbay was for 100% of the net assets of Copper Mountain and their 100% owned subsidiaries ("100% owned entities") and a 75% ownership in CMBC. The aggregate purchase consideration for the acquired assets, net of the liabilities assumed is as follows:

The fair value of the common shares issued was based on Hudbay's listed share price of C$6.87 at the June 20, 2023 acquisition date. Immediately prior to the acquisition, Copper Mountain settled its outstanding restricted share units and performance share units through the issuance of shares and settled its stock options for replacement Hudbay options that were immediately settled in cash.

---

Hudbay incurred acquisition related costs of $6,752 during the six months ended June 30, 2023, mainly relating to external legal and advisory fees and due diligence costs, which were recorded in other expense in the consolidated income statements. In addition, Hudbay incurred share issuance costs of $188 and presented these as a deduction from share capital.

Identifiable assets acquired and liabilities assumed:

The fair value of the net assets was determined using a combination of market, income and cost methods. The fair value of the non-controlling interest was then computed at a 25% of the equity interest in CMBC.

The following presents the allocation of the final purchase price, resulting in recognized fair value amounts of identifiable assets acquired and liabilities assumed as follows: 

The fair values of mineral properties, low grade stockpile and other property, plant and equipment have been determined based on an independent valuation, using a combination of market, income and cost methods. In particular, the fair values of the mineral properties and low grade stockpile have been calculated using significant judgements and estimates.

Trade receivables acquired as part of the acquisition have a fair value of $8,764 which is equal to their gross contractual value. Other receivables acquired have a fair value of $10,346 which is equal to their gross contractual value. Trade and other receivables are expected to be collected during the next 12 months.

Hudbay provided advances to Copper Mountain prior to the acquisition date, which have been recorded as a purchaser loan.

Hudbay recognized goodwill as a result of the acquisition as follows:

---

The goodwill balance arose from the requirement to record deferred income tax liabilities measured at the tax effect of the difference between the fair values of the assets acquired and liabilities assumed and their tax bases. None of the goodwill recognized is expected to be deductible for income tax purposes.

The results of operations have been consolidated with those of the Company from the date of acquisition and included in the British Columbia operating segment.

5. Acquisition of Rockcliff Metals Corporation

On September 14, 2023, Hudbay acquired all of the issued and outstanding common shares of Rockcliff, as part of a court-approved plan of arrangement. In doing so, Hudbay obtained control of Rockcliff on September 14, 2023.

Management determined that substantially all of the fair value of the gross assets acquired is concentrated in the Talbot exploration property and therefore accounted for the transaction as an asset acquisition.

The purchase consideration paid was 2,675,324 Hudbay common shares and 517,460 Hudbay warrants. For asset acquisitions settled with equity, entities are required to record the net assets acquired based on the fair value of the assets received in exchange for the equity issued, unless that fair value cannot be estimated reliably. Hudbay incurred acquisition related costs of $518 during the third quarter of 2023, mainly relating to external legal and advisory fees and due diligence costs, which were capitalized and included as a cost of acquiring the net assets.

The fair value of the net assets acquired was determined using a combination of income and cost methods. In particular, the fair values of the exploration property have been calculated using significant judgements and estimates. The following presents the fair value amounts of identifiable assets acquired and liabilities assumed: 

---

6. Revenue and expenses

(a) Revenue

Hudbay's revenue by significant product types:

Consideration from the Company's stream agreements is considered variable (note 18). Gold and silver stream revenue can be subject to cumulative adjustments when the amount of precious metals to be delivered under the contract changes. As a result of changes in the Company's mineral reserve and resource estimate in the first quarter of 2024, the amortization rate by which deferred revenue is drawn down into income was adjusted and, as required, a variable consideration adjustment was made for all prior year stream revenues since the stream agreement inception date. This variable consideration adjustment for the six months ended June 30, 2024 resulted in a decrease in revenue of $3,849 (June 30, 2023 - increase in revenue of $4,885).

      (b) Depreciation and amortization

Depreciation of property, plant and equipment and amortization of intangible assets are reflected in the condensed consolidated interim statements of loss as follows:

---

      (c) Other expenses

The Arizona business unit held an option to acquire water rights and land, which expired during the first quarter of 2024 without being extended or exercised. The previously capitalized cost to maintain the option, net of accrued interest, of $8,133 is presented as part of write-down of PP&E.

On March 7, 2024, Hudbay and Marubeni Corporation executed an option agreement whereby Marubeni will fund certain minimum annual exploration expenditures for agreed upon properties. During the six months ended June 30, 2024, proceeds of $363 were received and recorded as other income.

---

      (d) Net finance expense

Other finance expense relates primarily to standby fees on Hudbay's revolving credit facilities and leases.

Commencing in the first quarter of 2024, Hudbay has entered into copper forward sales, copper costless collars and gold costless collars which are non-quotational pricing ("QP") contracts (note 23b). Subsequent movements in the fair value of non-QP contracts are recognized in change in fair value of financial instruments in the condensed consolidated interim statements of loss.

7. Short-term investments

Short-term investments include guaranteed investment certificates held with Canadian financial institutions. We currently hold two $20,000 guaranteed investment certificates that mature in March 2025 and June 2025, respectively.

---

8. Trade and other receivables

9. Inventories

¹Stockpile of inventory that is not expected to be processed until the end of the Copper Mountain mine life.

The cost of inventories recognized as an expense, including depreciation, and included in cost of sales amounted to $311,689 and $640,191 for the three and six months ended June 30, 2024 (three and six months ended June 30, 2023 - $265,555 and $470,465).

---

10. Other financial assets

11. Intangibles and other assets

Intangibles and other assets of $50,375 (December 31, 2023 - $52,453) includes $46,836 of other assets (December 31, 2023 - $48,428) and $3,539 of intangibles (December 31, 2023 - $4,025).

Other assets represent the carrying value of certain future community costs that relate to original agreements with communities for the Constancia operation which allow Hudbay to extract minerals over the useful life of the Peru operation. The liability remaining for these costs is recorded in agreements with communities recorded at amortized cost (note 14). Amortization of the carrying amount is recorded in the condensed consolidated interim statements of loss within other expenses (note 6c) or exploration expenses, depending on the nature of the agreement.

Intangibles mainly represent computer software costs.

---

12. Property, plant and equipment

During the first quarter of 2024, Hudbay received a grant of $2,400 from the Environment and Climate Change Canada related to the purchase of an electric mining shovel in the third quarter of 2023. The carrying amount of the shovel has been deducted by the amount of the grant received. The grant will be recognized in profit or loss over the life of the shovel as a reduced depreciation expense. There were no significant unfulfilled conditions attached to the grant.

13. Other liabilities

---

14. Other financial liabilities

Agreements with communities recorded at amortized cost relate to agreements with communities near the Constancia operation which allow Hudbay to extract minerals over the useful life of the Constancia operation, carry out exploration and evaluation activities in the area and provide Hudbay with community support to operate in the region.

Equipment financing represents agreements that Hudbay has entered into to purchase mining equipment. Hudbay owns the assets and finances the payment of these assets over the specified term. These agreements expire between 2024 and 2029 with interest rates between 3.25% and 7.20% per annum.

As part of the streaming agreement for the 777 mine, Hudbay must repay, with precious metals credits, the stream deposit by August 1, 2052, the expiry date of the agreement. If the stream deposit is not fully repaid with precious metals credits from 777 production by the expiry date, a payment for the remaining amount will be due at the expiry date of the agreement. As the 777 mine has concluded all mining activities following the depletion of reserves and finalized the sales of produced concentrate, Hudbay concluded that the remaining stream deposit will not be repaid by means of precious metals credits from 777 production. The repayment amount is recorded as a Wheaton refund liability, which is and will be discounted at the 9.0% rate inherent in the original 777 stream agreement and accreted over the remaining term of the agreement.

---

15. Gold prepayment liability

        Gold prepayment liabilities are reflected in the condensed consolidated interim balance sheets as follows:

The following table summarizes changes in the gold prepayment liability:

During the first quarter of 2023, Hudbay renegotiated its agreements with various financial institutions and deferred eight months of scheduled gold deliveries. Monthly deliveries of the outstanding gold ounces under the new agreements have resumed in October 2023 and will continue until August 2024.

16. Lease liabilities

Lease liabilities are reflected in the condensed consolidated interim balance sheets as follows:

---

Hudbay has entered into leases which expire between 2024 and 2037. The interest rates on leases which were capitalized have interest rates between 2.50% and 8.49%, per annum. The range of interest rates utilized for discounting depends  mostly on Hudbay  acting as a lessee and duration of the lease. For certain leases, Hudbay has the option to purchase the equipment and vehicles leased at the end of the terms of the leases. Hudbay's obligations under these leases are secured by the lessor's title to the leased assets. The present value of applicable lease payments has been recognized as an ROU asset, which was included as a non-cash addition to property, plant and equipment, and a corresponding amount as a lease liability.

There are no restrictions placed on Hudbay by entering into these leases.

The following outlines expenses recognized within the Company's condensed consolidated interim statements of loss, relating to leases for which a recognition exemption was applied.

Payments made for short-term, low value and variable leases would mostly be captured as expenses in the condensed consolidated interim statements of loss, however, certain amounts may be capitalized to PP&E for the Arizona segment during its development phase and certain amounts may be reported in inventories given the timing of sales. Variable payment leases include equipment used for heavy civil works at Constancia.

---

17. Long-term debt

Long-term debt is comprised of the following:

(a) Senior unsecured notes

As at June 30, 2024, $1,165,863 aggregate principal amount of senior notes were outstanding in two series: (i) a series of 4.50% senior notes due 2026 ("2026 Notes") in an aggregate principal amount of $588,381 and (ii) a series of 6.125% senior notes due 2029 ("2029 Notes") in an aggregate principal amount of $577,482. During the quarter, the Company repurchased and retired $34,137 of senior unsecured notes at a discount. The discount of $366 recorded under Other expenses in the condensed consolidated interim statements of loss.

The senior notes are guaranteed on a senior unsecured basis by substantially all of the Company's subsidiaries, other than HudBay (BVI) Inc. and certain excluded or unrestricted subsidiaries, which includes CMBC (the Company's 75% owned subsidiary that owns the Copper Mountain mine), and subsidiaries that hold the Copper World and Mason projects as well as any newly formed or acquired subsidiaries that primarily hold or may develop non-producing mineral assets that are in the pre-construction phase of development.

(b) Senior secured revolving credit facilities

¹ Balance, representing deferred transaction costs, is in an asset position.

Hudbay has two senior secured revolving credit facilities with total commitments of $450 million and substantially similar terms and conditions for its Canadian and Peruvian businesses. Hudbay's revolving credit facilities are secured against substantially all of the Company's assets, other than those associated with the Copper World and Mason projects.

---

During the six months ended June 30, 2024, Hudbay repaid $10,000 under its Canadian revolving credit facility and $90,000 under the Peruvian revolving credit facility.

As at June 30, 2024, there were nil draws under the Canadian and Peruvian revolving credit facilities.

As at June 30, 2024, the Peru segment had nil in letters of credit issued under the Peru revolving credit facility to support its reclamation obligations and the Manitoba segment had $25,263 in letters of credit issued under the Canadian revolving credit facility to support its reclamation and pension obligations. As at June 30, 2024, we were in compliance with our covenants under the revolving credit facilities.

Surety bonds

The Arizona segment had $8,673 in surety bonds issued to support future reclamation and closure obligations. No cash collateral is required to be posted under these surety bonds.

The British Columbia segment had $47,976 in surety bonds issued to support future reclamation and closure obligations and $4,844 in surety bonds with BC Hydro in relation to the BC Hydro transmission system at the Copper Mountain Mine. No cash collateral is required to be posted under these surety bonds.

Other letters of credit

The Peru segment had $126,289 in letters of credit issued with various Peruvian financial institutions to support future reclamation and other operating matters. No cash collateral is required to be posted under these letters of credit.

The British Columbia segment had $2,260 in letters of credit issued with various Canadian financial institutions related to other operating matters. Cash collateral deposit has been posted under these letters of credit (note 10).

Hudbay has a C$130.0 million bilateral letter of credit facility ("LC Facility") with a major Canadian financial institution. As at June 30, 2024, the Manitoba segment had $55,360 in letters of credit issued under the LC Facility to support its reclamation and pension obligations.

18. Deferred revenue

Peru Stream Agreement

For the three and six months ended June 30, 2024, the drawdown rates for the Peru stream agreement for gold and silver were $817 and $14.56 per ounce, respectively (year ended December 31, 2023 - $820 and $15.26 per ounce, respectively).

---

The following table summarizes changes in deferred revenue:

Consideration from the Company's stream agreement is considered variable. Gold and silver stream revenue can be subject to cumulative adjustments when the number of ounces to be delivered under the contract changes. As a result of changes in the Company's mineral reserve and resource estimate in the first quarter of 2024, the amortization rate by which deferred revenue is drawn down into income was adjusted and, as required, a current period variable adjustment was made for all prior period stream revenues since the stream agreement inception date. This variable consideration adjustment resulted in a decrease in revenue of $3,849 and an increase of finance expense of $176 for the six months ended June 30, 2024 (December 31, 2023 - increase in revenue of $4,885 and a decrease of finance expense of $96).

Deferred revenue is reflected in the condensed consolidated interim balance sheets as follows:

---

19. Environmental and other provisions

Reflected in the condensed consolidated interim balance sheets as follows:

Decommissioning and restoration obligations ("DRO") are remeasured at each reporting date to reflect changes in discount rates, exchange rates, and timing and extent of cash outflows which can significantly affect the liabilities. This provision has been recorded based on estimates and assumptions that management believes are reasonable; however, actual decommissioning and restoration costs may differ from expectations.

During the six months ended June 30, 2024, the Company recorded a non-cash gain of $7,954 in the condensed consolidated interim statements of loss mainly related to a revaluation adjustment to the Flin Flon environmental reclamation provision. The first half of 2024 was impacted by an increase in long term, risk-free real discount rates based on changes in Canadian bond yields. Typically, an operating location will reflect any revaluation adjustments to the environmental reclamation provision against its reclamation assets. However, as the Flin Flon operations closed in June 2022, the corresponding Flin Flon assets have been fully depreciated and cannot be reduced below residual value resulting in the remaining impact being recorded as a gain in the condensed consolidated interim statements of loss.

As at June 30, 2024, decommissioning, restoration and similar liabilities have been discounted to their present value at rates ranging from 3.39% to 5.31% per annum (December 31, 2023 - 3.01% to 4.86%), using pre-tax, risk-free interest rates that reflect the estimated maturity of each specific liability.

During the six months ended June 30, 2023, the Company recorded a non-cash gain of $12,932 in the condensed consolidated interim statements of loss mainly related to a revaluation adjustment to the Flin Flon environmental reclamation provision.

---

(c) Equity-settled share-based compensation - stock options:

The Company's stock option plan was approved in June 2005 and amended in May 2008 (the "Plan"). Under the amended Plan, the Company may grant to employees, officers, directors or consultants of the Company or its affiliates options to purchase up to a maximum of 13 million common shares of Hudbay. The Company has determined that the appropriate accounting treatment is to classify the stock options as equity settled transactions.

The following table outlines the changes in the number of stock options outstanding:

The following table outlines stock options outstanding and exercisable:

Hudbay estimates expected life of options and expected volatility based on historical data, which may differ from actual outcomes.

---

22. Earnings per share

For periods where Hudbay records a loss, Hudbay calculates diluted loss per share using the basic weighted average number of shares. If the diluted weighted average number of shares were used, the result would be a reduction in the loss, which would be anti-dilutive.

For the three months ended June 30, 2024, the determination of the diluted weighted-average number of common shares excludes the impact of 433,927 weighted-average stock options and 133,088 warrants outstanding that were anti-dilutive as the Company recorded a loss in the financial period.

For the three and six months ended June 30, 2023, the determination of the diluted weighted-average number

of common shares excludes the impact of 257,941 and 274,398, respectively, weighted-average stock options outstanding  that were anti-dilutive as the Company recorded a loss in the financial period.

---

23. Financial instruments

(a) Fair value and carrying value of financial instruments:

The following presents the fair value ("FV") and carrying value ("CV") of Hudbay's financial instruments and non-financial derivatives:

---

Fair value hierarchy

The table below provides an analysis by valuation method of financial instruments that are measured at fair value subsequent to recognition as well as financial instruments not measured at fair value but for which a fair value is disclosed. Levels 1 to 3 are defined based on the degree to which fair value inputs are observable and have a significant effect on the recorded fair value, as follows:

- Level 1: Quoted prices in active markets for identical assets or liabilities;

- Level 2: Valuation techniques use significant observable inputs, either directly or indirectly, or valuations are based on quoted prices for similar instruments; and,

- Level 3: Valuation techniques use significant inputs that are not based on observable market data.

The Company's policy is to recognize transfers into and transfers out of fair value hierarchy levels as of the date of the event or change in circumstances that caused the transfer. During the three and six months ended June 30, 2024 and year ended December 31, 2023, Hudbay did not make any such transfers.

---

Valuation techniques used for instruments categorized in Levels 2 and 3 are consistent with the year ended December 31, 2023.

---

(c) Provisionally priced receivables

Changes in fair value of provisionally priced receivables

Hudbay records changes in fair value of provisionally priced receivables related to provisional pricing in concentrate purchase, concentrate sale and certain other sale contracts. Under the terms of these contracts, prices are subject to final adjustment at the end of a future period after title transfers based on quoted market prices during the quotation period specified in the contract. The period between provisional pricing and final pricing is typically up to three months.

Changes in fair value of provisionally priced receivables are presented in trade and other receivables when they relate to sales contracts and in trade and other payables when they relate to purchase contracts. At each reporting date, provisionally priced metals are marked-to-market based on the forward market price for the quotation period stipulated in the contract, with changes in fair value recognized in revenue for sales contracts and in inventory or cost of sales for purchase concentrate contracts. Cash flows related to changes in fair value of provisionally priced receivables are classified in operating activities.

As at June 30, 2024 and December 31, 2023, Hudbay's net position consisted of contracts awaiting final pricing are as indicated below:

The aggregate fair value of provisionally priced receivables within the copper and zinc concentrate at June 30, 2024, was an asset position of $3,373 (December 31, 2023 - an asset position of $22,635).

25. Supplementary cash flow information

(a) Other operating activities:

(b) Change in non-cash working capital:

(c) Non-cash transactions:

During the six months ended June 30, 2024 and 2023, Hudbay entered into the following non-cash investing and financing activities which are not reflected in the condensed consolidated interim statements  of cash flows:

- Remeasurement of Hudbay's decommissioning and restoration liabilities led to a net decrease in related property, plant and equipment assets of $8,215 (June 30, 2023 - a net increase of $27,151), mainly related to changes to real discount rates associated with remeasurement of the liabilities.

- Property, plant and equipment included $11,053 (June 30, 2023 - $4,708) of capital additions related to the recognition of ROU assets and $26,752 (June 30, 2023 - nil) of capital additions related to the recognition of property, plant and equipment that has been financed. Property, plant and equipment and other assets include $1,845 of capital additions related to agreements with communities (June 30, 2023 - $2,707).

26. Segmented information

Hudbay has the following reportable segments identified by the individual mining operations of Manitoba, British Columbia, Peru, as well as Arizona which holds our Copper World project. Corporate and other activities are not considered an operating segment and are included as a reconciliation to total consolidated results. No results for the British Columbia segment are reflected in the prior period comparative figures as Copper Mountain acquisition closed on June 20, 2023. Hudbay's second quarter 2023 loss was not materially affected by the acquisition as Copper Mountain had no revenues or corresponding cost of sales recorded during the 10 day stub period from the date of acquisition to the end of the second quarter 2023. Corporate and other activities include the Company's exploration activities in Chile, Canada and the State of Nevada. These exploration entities are not individually significant, as they do not meet the minimum quantitative thresholds for standalone segment disclosure.

SUMMARY

Delivered In-line Second Quarter Operating and Financial Results; Production Guidance Reaffirmed and Cash Cost Guidance Improved

- Achieved consolidated copper production of 28,578 tonnes and gold production of 58,614 ounces in the second quarter of 2024, in line with quarterly production cadence expectations for 2024.

- Enhanced operating platform delivered a 32% increase in copper production and a 20% increase in gold production over the second quarter of 2023², reflecting the benefits of a larger diversified operating platform with the addition of Copper Mountain and the continued execution of operational efficiencies across the business.

- Strong cost control with consolidated cash cost¹ and sustaining cash cost¹ per pound of copper produced, net of by-product credits¹, in the second quarter of 2024 of $1.14 and $2.65, respectively, in alignment with the cadence of costs expected in 2024.

- Reaffirmed full year 2024 consolidated production guidance for all metals including 137,000 to 176,000 tonnes of copper and 263,000 to 319,000 ounces of gold as we expect stronger production in the second half of 2024 in accordance with our mine production profile.

- Improved 2024 annual operating cost guidance with decreased consolidated cash cost¹ guidance range of $0.90 to $1.10 per pound, a result of meaningful exposure to gold by-product credits and continued strong cost control.

- Peru operations continued to benefit from strong mill throughput, averaging approximately 85,000 tonnes per day in the second quarter despite a planned semi-annual mill maintenance shutdown. The Pampacancha stripping program to advance to higher grades later this year is well underway. The reduced mining from Pampacancha resulted in 19,217 tonnes of copper and 10,672 ounces of gold produced in the second quarter of 2024, in line with quarterly cadence expectations. Peru cash cost per pound of copper produced, net of by-product credits¹, in the second quarter was $1.78, an expected increase from the first quarter given lower planned production levels and a 17% decrease compared to the second quarter of 2023.

- Manitoba operations produced 43,488 ounces of gold in the second quarter of 2024 as New Britannia continues to operate well above nameplate capacity and budgeted throughput levels. Manitoba cash cost per ounce of gold produced, net of by-product credits¹, was $771 during the second quarter of 2024, similar to the first quarter, and a decrease of 30% compared to the same quarter last year.

- British Columbia operations produced 6,719 tonnes of copper at a cash cost per pound of copper produced, net of by-product credits¹, of $2.67 in the second quarter. Cash cost improved by 23% over the first quarter, reflecting ongoing operational stabilization efforts as mine stripping activities are accelerated and mill improvement initiatives are underway at Copper Mountain.

- Achieved revenue of $425.5 million and operating cash flow before change in non-cash working capital of $122.0 million in the second quarter of 2024.

- Second quarter net loss attributable to owners and loss per share attributable to owners were $16.6 million and $0.05, respectively. After adjusting for items on a pre-tax basis such as a non-cash gain of $2.7 million related to a quarterly revaluation of our closed site environmental reclamation provision, a $10.7 million revaluation loss related to the gold prepayment liability, unrealized strategic gold and copper hedges and investments and a $2.1 million write-down of PP&E, among other items, second quarter adjusted earnings¹ per share attributable to owners was nil.

- Net loss attributable to owners of $16.6 million in the second quarter was meaningfully impacted by tax expense of $20.8 million despite having earnings before tax of only $0.4 million. The elevated tax expense was due to mining taxes that are calculated based on taxable mining profits in each operating jurisdiction, the limited deductibility of certain expenses and foreign exchange fluctuations on deferred tax balances.

- Adjusted EBITDA¹ was $145.0 million during the second quarter of 2024.

- Cash and cash equivalents and short-term investments increased by $274.0 million to $523.8 million during the first half of 2024 due to a successful equity offering and strong operating cash flows bolstered by higher copper and gold prices enabling a $405.9 million reduction in net debt¹ during the first half of 2024.

Accelerated Deleveraging and Transformed Balance Sheet

- Hudbay's unique copper and gold diversification in Peru and North America provides exposure to higher copper and gold prices and attractive free cash flow generation.

- Achieved trailing 12 month adjusted EBITDA¹ of $824.3 million, a substantial increase from $407.1 million for the 12 months ending June 30, 2023.

---

- Completed successful equity offering on May 24, 2024 for gross proceeds of $402.5 million and net proceeds of $386.2 million, net of transaction costs, to accelerate growth and deleveraging.

- Significantly accelerated deleveraging efforts. Repaid all $90.0 million of advances outstanding on the senior secured credit facilities during the second quarter of 2024 and made open market purchases of approximately $34.1 million of our senior unsecured notes in June 2024, at a discount to par. Long-term debt reduced to $1,155.6 million at June 30, 2024 from $1,278.6 million at March 31, 2024.

- Reduced net debt¹ to $631.8 million in the second quarter of 2024, reflecting a reduction of $405.9 million over the first half of 2024.

- The increase in cash and reduction in long-term debt significantly reduced our net debt to adjusted EBITDA¹ to 0.8x at June 30, 2024 compared to 1.6x at the end of 2023. Achieved the targeted 1.2x net debt to adjusted EBITDA ratio outlined in our three prerequisites plan (the "3-P plan") for advancing Copper World well ahead of schedule.

- Deleveraging efforts continued into the third quarter of 2024 with an additional $48.5 million of open market purchases of our senior unsecured notes in July and August.

- Scheduled to complete the final payment under the gold prepay liability in August 2024, which was the financing instrument used to fund the refurbishment of the New Britannia gold mill. The elimination of the gold prepay will further increase the Company's exposure to higher gold production in Snow Lake.

- Total liquidity substantially increased by 65% to $948.5 million at June 30, 2024 from $573.7 million at the end of 2023.

Continued Execution of Growth Initiatives to Further Enhance Copper and Gold Exposure

- Successfully ratified multi-year agreements with the unions representing members of our workforce in Peru and Manitoba, with no disruption to operations, demonstrating our focus on working closely with our employees and community stakeholders to ensure aligned economic and social benefits.

- Stripping program for the next mining phase at Pampacancha is underway and is expected to lead to significantly higher copper and gold grades in the fourth quarter of 2024, which together with maintaining strong operating performance at Constancia is expected to continue to generate meaningful free cash flow in Peru.

- The New Britannia mill continued to exceed expectations, driving higher gold production in Manitoba. The mill achieved record throughput levels of nearly 2,100 tonnes per day in June and averaged 1,850 tonnes per day in the second quarter, exceeding its original design capacity of 1,500 tonnes per day and its 2024 budgeted capacity of 1,800 tonnes per day due to the successful implementation of process improvement initiatives and effective preventative maintenance measures.

- Post-acquisition plans to stabilize the Copper Mountain operations remain in progress with a focus on mining fleet ramp-up activities, accelerated stripping and increasing mill reliability. Higher mill availability of 94% and better-than-planned copper recoveries of 82% were achieved in the second quarter of 2024.

- The development of an access drift to the 1901 deposit in Snow Lake remains on track to reach mineralization in early 2025 and is intended to enable confirmation of the optimal mining method for the deposit and underground drilling to further evaluate the orebody and upgrade inferred gold resources to reserves.

- Continued to progress the 3-P plan for sanctioning Copper World, with transformed balance sheet nearing targeted levels and remaining key state permits progressing on track and expected in 2024.

- Drill permitting for highly prospective Maria Reyna and Caballito properties near Constancia continues to advance through the multi-step regulatory process with the environmental impact assessment application approved for Maria Reyna in June and the Caballito application progressing through the review stage.

- Results from the winter 2024 exploration program in Snow Lake confirm two mineralized zones located 400 metres northwest of Lalor with an intersection of 9 metres grading 2.88% copper and 6.27 grams per tonne gold. Also identified follow-up targets for a summer 2024 drill program to test new geophysical anomalies, complete follow-up drilling at Lalor Northwest and complete regional drilling at the Snow Lake satellite properties.

- Continuing to advance Flin Flon tailings reprocessing opportunities through metallurgical test work and early economic evaluation to assess the possibility of producing critical minerals and precious metals while reducing the environmental footprint.

- Published 2023 annual sustainability report in June 2024, demonstrating meaningful progress towards achieving our long-term sustainability goals and commitments with many 2023 activities focused on "our people, our communities and our planet".

Summary of Second Quarter Results

Cash generated from operating activities was $138.5 million during the second quarter of 2024, an increase of $113.9 million compared to the same period in 2023. Operating cash flow before change in non-cash working capital was $122.0 million during the second quarter of 2024, reflecting an increase of $66.1 million compared to the second quarter of 2023. The increase in operating cash flows before change in non-cash working capital was primarily the result of higher copper and gold sales volumes partially from incremental contributions from the Copper Mountain mine and higher gold production in Manitoba, strong operational cost performance across the business and higher realized metal prices. This was partially offset by a significant increase in cash taxes paid of $12.9 million mainly at our Peru operations, compared to the same period in 2023. It was also partially offset by lower copper sales volumes in Peru and lower zinc sales volumes in Manitoba due to timing of shipments.

Consolidated copper, gold and silver production in the second quarter of 2024 increased by 32%, 20% and 21%, respectively, compared to the same period in 2023 primarily due to meaningfully higher recoveries in Peru and Manitoba, higher throughput at all sites and incremental production from the Copper Mountain mine. Consolidated zinc production in the second quarter of 2024 decreased by 8% compared to the same period in 2023 primarily due to lower planned zinc grades.

Net loss attributable to owners and loss per share attributable to owners in the second quarter of 2024 were $16.6 million and $0.05, respectively, compared to $14.9 million and $0.05, respectively, in the second quarter of 2023. The 2024 results were meaningfully impacted by tax expense of $20.8 million despite having earnings before tax of only $0.4 million in the quarter. The elevated tax expense was due to mining taxes that are calculated based on taxable mining profits in each operating jurisdiction, the limited deductibility of certain expenses and foreign exchange fluctuations on deferred tax balances. The 2024 results were also impacted by various non-cash charges for unrealized losses on strategic copper and gold hedges, revaluation of share-based compensation due to a higher share price and the revaluation of our gold prepayment liability to higher gold prices.

Adjusted net earnings attributable to owners¹ and adjusted net earnings per share attributable to owners¹ in the second quarter of 2024 were $0.1 million and nil per share, respectively, after adjusting for a $10.7 million revaluation loss related to the gold prepayment liability and revaluation of our strategic gold and copper hedges and investments, an $8.8 million revaluation of our share-based compensation due to a higher share price and a $2.1 million write-down of PP&E, among other items. This compares to adjusted net loss attributable to owners¹ and net loss per share attributable to owners¹ of $18.3 million, and $0.07 in the same period of 2023.

Second quarter adjusted EBITDA¹ was $145.0 million, compared to $81.2 million in the same period in 2023. The increase of 79% is the result of higher copper and gold sales volumes, higher realized metal prices and continued cost control leading to lower cash costs per unit both before and after by-product credits, in addition to the incremental contributions from the Copper Mountain mine.

In the second quarter of 2024, consolidated cash cost per pound of copper produced, net of by-product credits¹, was $1.14, compared to $1.60 in the same period in 2023. This decrease was mainly the result of higher copper production and significantly higher by-product credits, partially offset by higher mining, milling and G&A costs from incorporating Copper Mountain. Consolidated sustaining cash cost per pound of copper produced, net of by-product credits¹, was $2.65 in the second quarter of 2024 compared to $2.73 in the same period in 2023. This decrease was primarily due to the same reasons outlined above partially offset by higher cash sustaining capital expenditures.

Consolidated all-in sustaining cash cost per pound of copper produced, net of by-product credits¹, was $3.07 in the second quarter of 2024, and is marginally higher than $2.98 in the same period in 2023 due to higher corporate selling and administrative expenses mainly from revaluation of share-based compensation with a higher share price and higher amortization of non-operational community agreement costs.

As at June 30, 2024, total liquidity was $948.5 million, including $483.8 million in cash and cash equivalents, $40.0 million in short-term investments as well as undrawn availability of $424.7 million under our revolving credit facilities. Net debt¹ declined substantially by $362.4 million during the second quarter of 2024 to $631.8 million as part of our efforts to deleverage the balance sheet. This was driven by the free cash flow generation from the operations and our equity offering which contributed cash of $386.2 million, net of transaction and issuance costs. Some of these funds were utilized to repay all $90.0 million of debt outstanding on the senior secured credit facilities as at March 31, 2024 and to repurchase and retire approximately $34.1 million of our senior unsecured notes. As a result, we have made significant progress towards achieving our deleveraging targets outlined in our 3-P plan for sanctioning Copper World. We expect that our current liquidity together with cash flows from operations will be sufficient to meet our liquidity needs for the next year.

RECENT DEVELOPMENTS

Production Guidance Reaffirmed and Cash Cost Guidance Improved

We have reaffirmed our full year 2024 consolidated production guidance for all metals, including 137,000 to 176,000 tonnes of copper and 263,000 to 319,000 ounces of gold as we expect stronger production in the second half of 2024 in accordance with our mine production profile. We expect 2024 consolidated copper production to be below the midpoint of the guidance range, while 2024 consolidated gold production is expected to be above the midpoint of the guidance range. This is a result of a combination of lower than expected grades and timing impacts from heavy rains in Peru, as well as the ongoing ramp-up of stabilization efforts at Copper Mountain, offset by the continued strong operational performance in Manitoba driven by New Britannia performance and grades exceeding our expectations.

We have improved our 2024 annual consolidated cash cost guidance range to $0.90 to $1.10 per pound from the original guidance range of $1.05 to $1.25 per pound, as a result of meaningful exposure to gold by-product credits and continued strong cost control. We have reaffirmed all other 2024 guidance metrics.

Enhanced Balance Sheet through Successful Equity Offering and Accelerated Debt Reduction

We took several prudent measures in the second quarter of 2024 to further improve  balance sheet position, including more than $150 million of combined debt repayments and gold prepayment liability reductions:

• Completed successful $402.5 million equity offering - On May 24, 2024, we closed a public offering of common shares for gross proceeds of $402.5 million, resulting in net proceeds of $386.2 million after transaction costs.

• Fully repaid $90.0 million outstanding under the revolving credit facilities - We fully repaid $90 million of debt outstanding under our revolving credit facilities during the quarter with no remaining amounts drawn (other than letters of credit).

• Repurchased and retired $34.1 million of senior unsecured notes - We made open market purchases of $11.6 million of the 2026 senior unsecured notes and $22.5 million of the 2029 senior unsecured notes during the quarter.

• Delivered $24.0 million under gold forward sale and prepay agreement - We completed three additional months of gold deliveries during the quarter and are scheduled to fully repay the gold prepay facility by the end of August 2024, which was used to fund the refurbishment of the New Britannia gold mill.

As a result of these deleveraging efforts and continued cash flow generation, we have substantially reduced net debt¹ to $631.8 million at June 30, 2024, from $1,037.7 million at the end of 2023. The net debt reduction, together with higher levels of adjusted EBITDA¹  over the last twelve months, has significantly improved our net debt to adjusted EBITDA ratio¹ to 0.8x compared to 1.6x at the end of 2023. 

Subsequent to the quarter, deleveraging efforts continued in July and August with an additional $48.5 million of open market purchases of the senior unsecured notes, at a discount.

The improved balance sheet flexibility and accelerated debt reduction significantly advances the company's progress as part of its 3-P plan for sanctioning Copper World, and results in the successful achievement of the targeted 1.2x net debt to adjusted EBITDA ratio well ahead of schedule.

Disciplined Capital Allocation Driving Increased Copper and Gold Exposure

We continued to deliver positive free cash flow generation this quarter with strong gold production in Manitoba and strong cost control across the operations, while advancing planned stripping activities in Peru and British Columbia to drive higher copper and gold production levels in the second half of 2024. We also continue to evaluate areas to further improve mill performance across the business as part of our continuous improvement efforts.

____________________________________________
¹ Adjusted EBITDA and net debt to adjusted EBITDA ratio are non-IFRS financial performance measures with no standardized definition under IFRS. For further information and a detailed reconciliation, please see discussion under the "Non-IFRS Financial Performance Measures" section of this MD&A.

---

In addition to enhancing balance sheet flexibility through debt repayments as mentioned above, the net proceeds of the equity offering are intended to fund near-term growth initiatives, including acceleration of mine pre-stripping activities and mill optimization initiatives at Copper Mountain, and to evaluate mill throughput enhancement opportunities at Constancia and New Britannia.

Copper Mountain Stabilization Efforts to Drive Higher Copper Production

The key elements of Hudbay's stabilization plans for Copper Mountain include executing a campaign of accelerated stripping to access higher grades and implementing several plant improvement initiatives to increase mill throughput and recoveries.

Earlier this year, we commenced a three-year accelerated stripping program to mitigate the substantially reduced stripping that occurred over the four years prior to Hudbay's acquisition. We have successfully remobilized all 28 haul trucks and added five additional haul trucks this year to execute the accelerated stripping campaign at a lower cost and avoid contractor mining costs. The accelerated stripping program is expected to improve operating efficiencies and lower unit operating costs.

Hudbay's mine plan as disclosed in the December 2023 technical report for Copper Mountain assumes a mill ramp up to its nominal capacity of 45,000 tonnes per day in 2025 and an expansion to the permitted capacity of 50,000 tonnes per day in 2027. Mill initiatives are progressing as planned for 2024, including reprogramming the mill expert system, installing advanced grinding control instrumentation, flotation operational strategy improvements and improved maintenance practices. In the second half of 2024, we are also accelerating various engineering studies to increase mill throughput to 50,000 tonnes per day earlier than was originally contemplated in the technical report.

We have exceeded the targeted $10 million in annualized corporate synergies and we are on track to realize our three-year annual operating efficiencies target.

New Britannia Mill Performance Exceeding Expectations to Drive Higher Gold Production

We completed the brownfield investment in New Britannia in 2021 and refurbished the mill to a nominal capacity of 1,500 tonnes per day. This provided additional processing capacity to our Snow Lake operations and allowed us to achieve higher gold recoveries of approximately 90% as Lalor transitioned to the higher gold and copper areas of the mine plan. The New Britannia mill has been consistently exceeding performance expectations, achieving 1,650 tonnes per day in 2023, more than 1,850 tonnes per day in the first half of 2024, and a new monthly record of nearly 2,100 tonnes per day in June 2024.

The final payment for the New Britannia gold prepay financing in August 2024 further enhances our exposure to higher gold production in Snow Lake. With approximately two million ounces of contained gold in current mineral reserve estimates and another 1.4 million ounces of contained gold in inferred mineral resources, the New Britannia investment has unlocked significant value in Snow Lake. This could be further enhanced by regional exploration upside and the current strong gold price environment.

In the first quarter of 2024, we received a permit approval to increase the production rate at New Britannia to 2,500 tonnes per day, which will provide the opportunity to process more Lalor ore at the New Britannia mill and create additional processing capacity for potential new regional discoveries in Snow Lake.

Peru Investment Programs to Drive Higher Copper and Gold Production

We are well-advanced in executing a stripping program for the next mining phase at the Pampacancha pit. This stripping program is expected to continue until September and is intended to unlock higher copper and gold grades at the Peru operations in the fourth quarter of 2024.

During the second quarter of 2024, the Peruvian government approved regulatory changes to allow mining companies to increase their annual mill throughput levels up to 10% above permitted levels. We are evaluating the potential to increase planned production levels at Constancia, as early as 2026, which could partially offset the grade declines after the completion of mining at Pampacancha in late 2025.

Advancing Permitting at Copper World

The first key state permit required for Copper World, the Mined Land Reclamation Plan, was initially approved by the Arizona State Mine Inspector in October 2021 and was subsequently amended and approved to reflect a larger private land project footprint. This approval was challenged in state court, but the challenge was dismissed in May 2023. In late 2022, Hudbay submitted the applications for an Aquifer Protection Permit and an Air Quality Permit to the Arizona Department of Environmental Quality. The public comment period for the Aquifer Protection Permit was completed in the second quarter while the public comment period for the Air Quality Permit commenced in July. Hudbay continues to expect to receive these two outstanding state permits in the second half of 2024.

Copper World is one of the highest-grade open pit copper projects in the Americas²  with proven and probable mineral reserves of 385 million tonnes at 0.54% copper. Copper World Phase I contemplates average annual copper production of 85,000 tonnes over a 20-year mine life, at average cash costs and sustaining cash costs of $1.47 and $1.81 per pound of copper, respectively. In addition, there remains approximately 60% of the total copper contained in measured and indicated mineral resources (exclusive of mineral reserves), providing significant potential for a Phase II expansion and mine life extension. The inferred mineral resource estimates are at a comparable copper grade and also provide significant upside potential. Copper World is expected to provide meaningful copper to support the U.S. domestic supply chain.

Manitoba Exploration Update

Lalor Northwest Follow-up Drilling Confirms Two Mineralized Zones

Hudbay's 2024 winter drill program included follow-up drilling of a geophysical anomaly located northwest of Lalor, which was initially drilled in 2023. Recent positive assay results at Lalor Northwest confirm the discovery of two mineralized zones located within 400 metres of the existing Lalor underground infrastructure.

In 2023, hole CH2302 intersected two mineralized zones, including 4.8 metres at 2.97% copper, 2.92 grams per tonne gold and 80.3 grams per tonne of silver. Earlier in 2024, hole CH2406 intersected the same two mineralized zones, including 9.0 metres of 2.88% copper, 6.27 grams per tonne of gold and 88.9 grams per tonne of silver. See "Qualified Person and NI 43-101".

These promising results justified additional follow-up drilling in the summer of 2024 with two drill rigs currently turning at Lalor Northwest. Drilling results are expected to be received by the end of the year and will be used to determine the potential size of Lalor Northwest and the potential for future underground drift development from Lalor for further definition drilling. Lalor Northwest has the potential to add near-term production growth at Lalor, extend mine life and create additional value from our Snow Lake operations.

Snow Lake 2024 Regional Geophysics Program Identifies Prospective Targets; Summer Drill Program Initiated

During the first half of 2024, Hudbay conducted the company's largest geophysics program in its history in Snow Lake. This program resulted in the identification of a number of anomalies and prospective targets across the Snow Lake tenements which are currently being tested near the former Reed and Anderson mines and in the vicinity of the Bur and Rail deposits that were acquired as part of the Rockcliff transaction. Hudbay intends to continue similar size geophysical programs and mapping of our consolidated land package in the region in 2025.

The 2024 geophysical program included surface electromagnetic (EM) surveys covering a 25 square kilometre area including the recently acquired Cook Lake claims that had been previously untested by modern deep geophysics, which was the discovery method for the Lalor deposit. This surface EM survey used cutting-edge techniques that enabled the team to detect deep targets at depths of over 1,000 metres below surface. The new EM methodology is unique to Hudbay and will lead to advanced understanding of the mineralization at depths previously undetectable.

---

In addition, one very strong deep anomaly located at Cook Lake North, approximately six kilometres from Lalor, was identified through borehole EM surveys. 2024 drilling intersected multiple horizons of non-economic mineralization but a deeper and stronger conductor will be tested in the coming weeks by extending the drill hole at depth as part of our summer-fall 2024 exploration program.

Hudbay continues to execute its 2024 drilling program with the goal of extending known mineralization near the Lalor deposit to further extend mine life as well as to find a new anchor deposit within trucking distance of the Snow Lake processing infrastructure. The 2024 summer drill program is well underway, and we currently have six drill rigs turning in Snow Lake, including two drills at Lalor Northwest as mentioned above. We expect to ramp up to eight drill rigs by the end of August to test new geophysical targets and complete follow-up drilling at potential regional satellite deposits. Results from the summer drill program are expected in late 2024.

Advancing Access to the 1901 Deposit

In the first quarter of 2024, we commenced the development of a smaller profile drift from the existing Lalor ramp towards the 1901 deposit. The 1901 development drift is expected to reach the mineralization in early 2025, following which we plan to conduct definition drilling intended to confirm the optimal mining method, evaluate the orebody geometry and continuity, and convert inferred mineral resources in the gold lenses to mineral reserves. Pending positive results from the drilling programs, the plan is to initiate a haulage drift and other related mining infrastructure in 2025 and 2026 in anticipation of full production from the 1901 deposit in 2027.

Continuing to Advance Studies for Flin Flon Tailings Reprocessing

Hudbay continues to advance studies to evaluate the opportunity to reprocess Flin Flon tailings where more than 100 million tonnes of tailings have been deposited for over 90 years from the mill and the zinc plant. The studies are evaluating the potential to re-purpose the existing Flin Flon concentrator, which is currently on care and maintenance, with flow sheet modifications to reprocess tailings to recover critical minerals and precious metals while creating environmental and social benefits for the region.

We continue to advance metallurgical test work, and during the second quarter of 2024, we received results from the initial confirmatory drill program in the section of the tailings facility that was utilized by the zinc plant. The results confirmed the grades of precious metals and critical minerals previously estimated from historical zinc plant records. An early economic study to evaluate the opportunity to reprocess initially the portion where the zinc plant tailings were deposited has shown promising results that warrant further engineering work in the second half of 2024. A similar study is planned in respect of the mill tailings.

Peru Exploration Update

Hudbay controls a large, contiguous block of mineral rights with the potential to host mineral deposits in close proximity to the Constancia processing facility, including the past producing Caballito property and the highly prospective Maria Reyna property. The company commenced early exploration activities at Maria Reyna and Caballito after completing a surface rights exploration agreement with the community of Uchucarcco in August 2022. As part of the drill permitting process, environmental impact assessment applications were submitted for the Maria Reyna property in November 2023 and for the Caballito property in April 2024. The environmental impact assessment (EIA) for Maria Reyna was approved by the government in June 2024 and the Caballito application continues to make progress through the permitting process. This represents one of several steps in the drill permitting process, which is expected to take approximately 12 months to complete after the EIAs are approved.

New Concentrate Contracts with Attractive Terms

In light of the extremely tight copper concentrate market that currently exists, Hudbay has strategically taken steps to preserve uncommitted copper concentrate units. This has allowed us to enter into several new contracts covering approximately 20% to 25% of our estimated Constancia concentrate sales over the next four years with favourable treatment and refining charges ("TC/RC"), including contracts with fixed TC/RCs that are negative in certain years and other contracts that have TC/RC priced at significant discounts of 45% to 65% to market benchmark terms.

Collective Bargaining Agreements Ratified in Manitoba and Peru

In June, new three-and-a-half year collective bargaining agreements were ratified by the members of all five unions at our Manitoba operations, effective July 1, 2024. In July, a new three-year agreement was signed with the union at our Peru operations, effective November 10, 2023. The ratification of these agreements is a significant achievement and demonstrates Hudbay's focus on working closely with our employees and community stakeholders to ensure aligned economic and social benefits.

Dividend Declared

A semi-annual dividend of C$0.01 per share was declared on August 12, 2024. The dividend will be paid out on September 20, 2024 to shareholders of record as of close of business on September 3, 2024.

SUSTAINABILITY

Hudbay published its 2023 annual sustainability report in June, providing transparency and progress on key business accomplishments and sustainability initiatives in 2023, along with goals for the upcoming year and longer term. Hudbay's purpose statement serves as the cornerstone for our commitment to sustainability: "We care about our people, our communities and our planet. Hudbay provides the metals the world needs. We work sustainably, transform lives and create better futures for communities."

Highlights from our 2023 annual sustainability report include:

Our Planet

• In 2023, we made meaningful progress on our roadmap towards the overall goal of a 50% reduction in Scope 1 and Scope 2 greenhouse gas ("GHG") emissions by 2030³ . The roadmap helps identify initiatives across the organization, categorize their potential impacts and plan their annual progression.

• In 2023, direct energy consumption decreased 11% and indirect energy consumption increased 21% from the prior year primarily as a result of the addition of the Copper Mountain mine in 2023. Total GHG intensity per tonne of copper equivalent production decreased 8% compared to 2022.

• Approximately 55% of total energy consumption came from renewables, with nearly 100% of electricity at our Manitoba and British Columbia operations sourced from renewable hydropower.

• In 2023, we reduced the total amount of water withdrawn by 6% and water discharged by approximately 37% compared to 2022. Approximately 77% of total water use was recycled or reused.

• Hudbay commits to implementing the Mining Association of Canada's Towards Sustainable Mining (TSM) program. All business units achieved a level A or higher TSM rating across all TSM Climate Change Protocol indicators, and Manitoba and Peru received level AA ratings for the facility climate change management indicator. Hudbay also achieved a level A rating for the corporate-focus indicator related to setting meaningful targets for emissions reduction and focusing on climate adaptation.

• Constancia signed a 10-year power purchase agreement with ENGIE Energía Perú, providing access to a 100% renewable energy supply for Constancia beginning in 2026.

• Copper Mountain ranks among the lowest quartile for GHG emissions among copper mines and has the only electric trolley-assist system in North America, with seven trolley-capable haul trucks in operation that use hydroelectricity and reduce diesel consumption. In October 2023, we commissioned the world's largest electric hydraulic excavator, adding to the two other electric excavators in the British Columbia's operation electric fleet.

• In Manitoba, we conducted metallurgical research with technology partners to explore the potential for reprocessing Flin Flon tailings to produce non-acid-generating residual tailings. This has the potential to reduce the on-site waste that contributes to ongoing water treatment requirements, create a new mineral resource and extend the life of the Flin Flon operations.

____________________________________________
³ Hudbay's climate change targets were established in 2022 and are based on a 2021 baseline for Scope 1 and Scope 2 GHG emissions from existing operations. The targets exclude the British Columbia operations which were acquired in 2023, and the company is evaluating the impact of the British Columbia operations on Hudbay's GHG reduction roadmap.

---

• In September 2023, we released the pre-feasibility study (PFS) for Phase I of our Copper World development project in Arizona. The PFS includes the addition of a concentrate leach facility in the fifth year of operations to produce copper cathode, which is estimated to lower energy consumption by more than 10% and decrease GHG and sulfur dioxide emissions by eliminating overseas shipping, smelting and refining activities associated with copper concentrate.

Our People

• In Peru, Constancia received the "Healthy Company Management" certificate from SGS Peru, one of the world's leading testing, inspection and certification companies, in recognition of its management practices, processes and systems related to health and well-being.

• In Manitoba, the business unit leader spearheaded the launch of the "Home Safe Everyday Initiative." This program revolves around a roadmap comprising three key work streams - Safety Governance, Supervisory Leadership, and High Potential Prevention and Mitigation - to prevent incidents by thoroughly assessing risks and implementing controls to reduce their frequency.

• In British Columbia, following Hudbay's acquisition of Copper Mountain, the human resources team adapted to the changing business needs focusing on recruiting for critical positions, such as mill operators, and building a positive organizational culture, which will continue into 2024.

• Launched the "ONETeam" leadership training program in 2023 to focus on coaching and conflict resolution skills in a six-day leadership development program for supervisors and upper-level management. In Manitoba, supervisors completed the program in February 2024, while the British Columbia business unit plans to roll it out in the fall of 2024.

• In Arizona, Hudbay is establishing a strong workplace safety culture with the hiring of a dedicated health and safety manager, who initiated safety programs including a critical risk management program, an all-volunteer emergency response team, and a monthly employee-led safety meeting where a team member selects and presents a relevant and timely safety topic.

• Nine of the ten directors on our Board are independent, non-executive directors. Hudbay's President and CEO, Peter Kukielski, is the only executive director.

• Among the directors, 40% are women and a further 20% are from other designated groups. The Board remains committed to a company target of having at least 30% women directors on the Board as part of its overall commitment to diversity and inclusion.

Our Communities

• Hudbay navigated through a period of nationwide social unrest in early 2023 and was able to keep the Constancia mill operating due in large measure to the efforts of community members near Constancia.

• In 2023, we signed new sustainable development agreements with six communities in the area near Constancia and engaged in nearly 7,700 interactions involving more than 3,000 local stakeholders.

• Our Manitoba business unit expanded its Indigenous Circle for Everyone (ICE) program in 2023 offering employees a comprehensive exploration of the cultural aspects of the neighbouring First Nations communities.

• In British Columbia, we held regular meetings with representatives from the Towns of Princeton and Keremeos, RDOS, outfitters, ranchers and trappers. We also began the process of amending the existing participation agreements with local First Nations to provide a more meaningful and aligned relationship.

• In Arizona, we continued to meet with leadership and council members of local Native American tribes at the Copper World site to discuss the project and create opportunities for them to express concerns and provide feedback. We are also responding to public comments received on the draft permits for Copper World, which were issued by the Arizona Department of Environmental Quality in 2024.

We are pleased with the steps taken in 2023 towards our long-term sustainability goals. Details of our sustainability results can be found on our website.

Overview

Peru operations continued to benefit from strong mill throughput, averaging approximately 87,000 tonnes processed per day year-to-date, as well as higher realized prices of all metals. Cost performance was also strong, achieving lower unit operating costs, cash cost and sustaining cash cost compared to the comparative 2023 periods. Cash cost also benefited from higher by-product sales revenues of gold, silver and molybdenum throughout 2024.

Mining efforts at Pampacancha are focused on continuing the stripping program to advance to the next mining phase and we are on track to resume mining in higher copper and gold grade areas later in the year.

During the quarter, the Peruvian Ministry of Energy and Mines approved a regulatory change, Supreme Decree 011-2024-EM, to allow mining companies in Peru to increase throughput by up to 10% above permitted levels. Previously, the regulation only allowed for an increase of up to 5%. As such, we are evaluating the potential to increase future production at Constancia.

Mining Activities

Total ore mined in the second quarter of 2024 increased by 8% compared to the same period in 2023 in line with our mine plan. Ore mined from Pampacancha during the second quarter decreased to 1.3 million tonnes compared with 2.4 million tonnes in the same period in 2023 as a result of higher capitalized stripping activities.

Year-to-date ore mined was 10% higher than the same period in 2023 due to the same factors as the quarterly variance as well as the comparative 2023 period having reduced mining activity in order to ration fuel during regional protests and social unrest in Peru.

---

Milling Activities

Ore milled during the second quarter of 2024 was 7% higher than the comparative 2023 period mainly due to the treatment of softer ore from stockpiles. Ore milled included supplemental ore feed from stockpiles during the quarter as the team advances pit stripping activities. Milled copper and gold grades decreased by 3% and 22%, respectively, in the second quarter of 2024 compared to the same period in 2023 due to lower amounts of high grade copper and gold from Pampacancha as the stripping campaign is underway, in addition to lower grades from the processing of stockpiled ore. 

Ore milled during the first half of 2024 was 6% higher than the comparative 2023 period due to the same factors as the quarterly variance. Milled copper grade increased by 3% in the first half of 2024 compared to the same period in 2023 due to an increase in the mining of higher grade copper ore from Pampacancha during the period. Gold grades increased by 22% compared to the same period in 2023 due to additional tonnes of ore milled from Pampacancha in the first quarter of 2024.

Recoveries of copper and gold during the second quarter of 2024 were 83%, and 61%, respectively, representing an increase of 4%, and 1%, respectively, compared with the same period in 2023 and were in line with our metallurgical models.

Recoveries of copper, gold and silver during the first half of 2024 were 84%, 70% and 68%, representing an increase of 4%, 18%, and 8%, respectively, compared with the 2023 period. This is also in line with our metallurgical models and is the result of ongoing recovery improvement initiatives.

Production and Sales Performance

Second quarter 2024 production of copper and silver was 19,217 tonnes and 450,833 ounces, respectively, representing an increase of 9% and 7%, respectively, compared with the same period in 2023 due to higher copper  recoveries and higher throughput. Production of gold and molybdenum in the second quarter of 2024 was 10,672 ounces and 369 tonnes respectively, representing a decrease of 18% and 11% from the comparative 2023 period primarily due to lower grades.

Year-to-date production of copper, gold and silver was 43,793 tonnes, 39,816 ounces and 1,090,551 ounces, respectively, representing an increase of 15%, 65%, and 12%, respectively, from the comparative 2023 period due to higher copper and silver grades from Pampacancha, higher gold grade due to additional tonnes of ore milled from Pampacancha, higher recoveries and higher throughput. Production of molybdenum in the first half of 2024 was 766 tonnes.

Quantities of payable copper, gold and silver sold during the second quarter of 2024 were 21%, 8% and 40%, respectively, lower than the corresponding period in 2023 primarily due to higher volume of copper concentrate sold in the second quarter of 2023 from the rapid reduction in the buildup of inventories after the social unrest during the first quarter of 2023.

Year-to-date copper, gold and silver metal sold was  8%, 113% and 8%, respectively, higher than the comparable period primarily as a result of higher production levels and a precious metal stream sale that was recognized in revenue shortly after the year end cutoff date in the first quarter of 2024.

Payable copper metal sold was also lower than the first quarter of 2024 due to lower copper production and 10,000 wet metric tonne copper concentrate shipment that remained unsold at the end of the second quarter and was recognized as revenue early in the third quarter of 2024.

---

Cost Performance

Combined mine, mill and G&A unit operating costs in the second quarter were $12.68 per tonne, 10% lower than the same period in 2023 primarily due to higher ore throughput.

Cash cost per pound of copper produced, net of by-product credits, in the second quarter of 2024 was $1.78, a decrease of 17% compared to the same period in 2023 due to higher copper production, higher by-product credits and lower treatment and refining charges. This was partially offset by higher profit sharing. On a year-to-date basis, cash costs pound of copper produced, net of by-product credits, in the first half of 2024 was $1.02, compared with $1.72, a significant decrease for the same reasons as stated for the quarterly decrease.

Sustaining cash cost per pound of copper produced, net of by-product credits, was $2.61 and $1.74 for the second quarter and first half of 2024, or 15% and 32%, respectively lower than the comparative 2023 periods primarily due to the same factors affecting cash cost.

Overview

Our Snow Lake operations in Manitoba maintained steady production results despite overcoming challenges in the second quarter of 2024, including forest fires and temporary production interruptions at the Lalor mine, partially offset by stronger than budgeted throughput at New Britannia. Our team's resilience and dedication ensured that we continued to operate effectively and efficiently while achieving our quarterly production targets.

A significant forest fire in the Flin Flon area in May 2024 temporarily impacted operations, causing workforce shortages due to road closures south of Flin Flon, which limited the ability for many employees to travel to Snow Lake and a number of employees were evacuated from their homes. We express our heartfelt gratitude to the brave individuals who battled the fire and those who supported essential community functions during this crisis.

At the Lalor mine, we encountered issues with the production hoist gearbox and electrical faults on the hoist drives, causing a ten-day stoppage in hoisting ore. Our maintenance teams collaborated closely with original equipment manufacturers to resolve these issues quickly. During the hoisting outage, the operations team focused on value-added activities, including underground ore buildup close to the shaft, waste filling, increased maintenance, building longhole inventory, and trucking ore to surface. Additionally, we implemented stope design modifications that yielded positive results by improving mucking efficiency throughout the lifecycle of our stopes.

The New Britannia mill consistently operated above nameplate capacity, achieving a new monthly record of nearly 2,100 tonnes per day in June. Ongoing efforts to increase throughput are aligned with our long-term objectives to maximize gold production by directing more gold ore from Lalor to the New Britannia mill for higher gold recoveries.

---

At the Anderson tailings facility, we achieved high deposition efficiency by utilizing new equipment and updated procedures allowing for the deferral of, dam construction capital to future years. We also received permit approval from Manitoba Environment and Climate Change to proceed with the sub-aerial tailings deposition trial, which is currently underway.

An extensive diamond drill grouting program was implemented at the 1901 exploration drift to establish a grout curtain and reduce water inflows and pressures to manageable levels. The drift is expected to reach mineralization by early 2025. This will be followed by definition drilling to further confirm the optimal mining method, evaluate orebody geometry and continuity, and convert inferred mineral resources in the gold lenses to mineral reserves.

Our Manitoba operation also progressed its sustainability initiatives by reducing propane and diesel consumption  in the first half of 2024 compared to the same period in 2023. In addition, at Lalor, an initiative to capture and recycle natural groundwater and use it as process water to reduce the freshwater intake into the mine has proven to be effective.

Mining Activities

Total ore mined in Manitoba in the second quarter of 2024 was 7% lower than the comparable quarter in 2023. Gold, copper, silver and zinc grades mined at Lalor during the second quarter were 8%, 15%, 4% and 12% lower, respectively, compared with the same period in 2023. These changes reflect the temporary Lalor mine production disruptions noted above and the completion of a planned lower grade mining sequence in the quarter.

Total ore mined at our Manitoba operations during the first half of 2024 was 1% higher than the same period in 2023. Gold, copper and silver grades mined at Lalor during the first half of 2024 were 7%, 12% and 10% higher, respectively, compared with the same period in 2023, consistent with the mine plan. Zinc grades mined at Lalor during the first half of 2024 were 12% lower than the same period in 2023.

Milling Activities

Consistent with our strategy of allocating more Lalor ore feed to New Britannia, the New Britannia mill throughput averaged approximately 1,850 tonnes per day in the second quarter of 2024, approximately 18% above average daily throughput levels in the comparative 2023 period. Recoveries of gold, copper and silver in the second quarter of 2024 were 90%, 94% and 83%, respectively, representing an increase of 2%, 4%, and 4%, respectively, compared to the same period in 2023. Year-to-date total ore milled at New Britannia was 19% higher than the prior period. Despite the higher throughput gold recoveries were maintained, while copper and silver increased by 4% and 3%, respectively.

During the three and six months ended June 30, 2024, the Stall mill processed 4% and 7%, respectively, less ore than the comparative 2023 period, which is aligned with our strategy of allocating more Lalor ore feed to New Britannia, as noted above.

Production and Sales Performance

Manitoba operations produced 43,488 ounces of gold, 2,642 tonnes of copper, 8,087 tonnes of zinc and 210,647 ounces of silver during the second quarter of 2024. Compared to the second quarter of 2023, production of gold and silver in the second quarter of 2024 increased by 23% and 17%, respectively, while production of copper and zinc declined by 5% and 8%, respectively. The increased gold and silver production in the quarter is mainly due to our strategy of mining and allocating more Lalor gold ore feed to New Britannia to achieve higher recoveries, which resulted in planned lower production of copper and zinc. 

Production of gold, copper and silver in the first half of 2024 was higher by 41%, 20% and 30%, respectively, than the comparative 2023 period mainly due to the same reasons as noted above, as well as higher production from copper-gold zones in the first quarter of 2024. Zinc production in the first half of 2024 decreased by 9%, aligned with forecasted production and strategy to mine more gold ore at Lalor.

---

Quantities of payable metal sold for the three and six months ended June 30, 2024 were higher for copper, gold and silver than the comparable periods in 2023 primarily due to the same factors impacting contained metal production, as noted above. Payable zinc metal sold was lower than the comparative 2023 period as there was a 10,000 wet metric tonne zinc concentrate shipment that remained unsold at the end of the second quarter and will be recognized as revenue in the third quarter of 2024.

   

Cost Performance

Total Lalor mine unit operating costs during the second quarter of 2024 increased by 11% compared to the same period in 2023 but were in line with expectations as a result of lower tonnage mined, lower capitalized development costs and longer haulage distances. Compared to the same period in 2023, unit operating costs at the Stall mill were 8% higher during the second quarter of 2024, primarily due to lower throughput. New Britannia unit operating costs decreased by 15% during the second quarter of 2024 versus the same period in 2023, primarily a result of higher throughput. Combined mine, mill and G&A unit operating costs in the second quarter of 2024 were C$225 per tonne, representing a 2% increase compared to the same period in 2023. Combined mine, mill and G&A unit operating costs in the first half of 2024 increased 6% to C$230 per tonne. The marginal increases in combined operating costs year-over-year were the result of lower capitalized development and higher haulage distances, which were partially offset by the effect of higher total throughput.

Cash cost per ounce of gold produced, net of by-product credits, in the second quarter of 2024 was $771 per ounce, a decrease of 30% compared to the same period in 2023 due to significantly higher gold production and higher by-product credits, partially offset by higher G&A costs.

Sustaining cash cost per ounce of gold produced, net of by-product credits, in the second quarter of 2024 was $1,163, a decrease of 24% compared to the same period in 2023, primarily due to the same factors affecting cash cost offset by higher sustaining capital costs during the quarter.

Cash cost per ounce of gold produced, net of by-product credits, in the first half of 2024 was $751 per ounce. These costs were 26% lower compared to the same period in 2023 primarily due to higher gold production and by-product credits, partially offset by higher G&A costs. Sustaining cash cost per ounce of gold produced, net of by-product credits, for the first half of 2024 was $1,042 per ounce, a decrease of 27% from the comparative 2023 period primarily due to the same factors affecting cash cost noted above, with sustaining capital expenditures similar to prior year.

² Copper Mountain mine results are stated at 100%. Hudbay owns 75% of Copper Mountain mine. As Copper Mountain was acquired on June 20, 2023, there was only included limited production from the Copper Mountain mine during the 10-day stub period. Copper Mountain's operations had no revenues or corresponding cost of sales recorded during the 10-day stub period from the date of acquisition to the end of the second quarter of 2023

Overview

Hudbay has been focused on advancing operational stabilization plans, including opening up the mine by adding additional mining faces, adding to the mining fleet, optimizing the ore feed to the plant and implementing plant improvement initiatives that mirror Hudbay's successful processes at Constancia. While the benefits of these stabilization plans are not expected to be fully realized until 2025, we have successfully increased the total tonnes moved and has seen stronger mill performance as demonstrated by higher mill availability of 94% and above-target copper recoveries of 82% in the second quarter of 2024. As a result, year-to-date mill performance has resulted in the highest mill availability and highest copper recoveries in the last decade.

Mining Activities

Total ore mined at Copper Mountain in the second quarter of 2024 was 2.2 million tonnes, a decrease compared to the first quarter of 2024. As planned, ore stockpiles were utilized as ore feed to the mill while the mine operation team increased waste stripping activities. Total material moved was continued to ramp up in the quarter as a result of effective usage of the mining fleet as part of the fleet production ramp up plan to execute the accelerated stripping program to access higher head grades. This plan entails remobilization of the existing mining truck fleet and the deployment of an additional shovel, drill and associated equipment. Earlier this year, we ordered five new haul trucks to execute additional stripping activities over the next three years at a lower cost than the contractor mining approach that was contemplated in the technical report. Three of the five new haul trucks and the additional shovel and drill were put in production in June, and all five haul trucks were in operation by August. As a result, total material moved is expected to continue to increase quarter-over-quarter as per the mine plan. 

Total ore mined at Copper Mountain in the first half of 2024 was 5.9 million tonnes, a 16% decrease compared to the second half of 2023 as we execute the planned accelerated stripping program and supplement ore feed from stockpiles, as mentioned above.

Milling Activities

The mill processed 3.2 million and 6.4 million tonnes of ore during the second quarter of 2024 and first half, respectively. Ore processed in the second quarter of 2024 was 2% higher than the first quarter of 2024 benefiting from stabilization and reliability initiatives within the mill processing circuit. The average mill availability during the second quarter of 2024 increased to 94% from 90% in the first quarter, while maintaining a stable throughput rate. Mill throughput in the second quarter of 2024 was limited by reduced reliability of the secondary crushing circuit, caused primarily by unplanned maintenance events and elevated clay material in the mine feed. During the quarter, a number of initiatives were advanced to address these issues and other identified constraints and improve throughput to targeted levels, with the benefits expected to be realized in the second half of 2024. Initiatives that began earlier in the year are progressing on target, including reprogramming the mill expert system, installation of advanced semi-autogenous grinding control instrumentation, redesign of the SAG liner package and updated operational procedures intended to remove magnetite from the pebble stream.

Maintenance practices to improve mill availability continue to be a key pillar of our stabilization initiatives. The first quarter planned maintenance shutdown focused on achieving 100% compliance to planned execution. Progress continued into the second quarter with the implementation of predictive strategies with vibration equipment/analysis and oil analysis and standard operating procedure enhancements. Work has begun to analyze the trade-off among the various alternatives to further enhance mill performance.

Milled copper grades during the second quarter of 2024 were 7% lower than the first quarter as we continued to draw on stockpiled ore. Copper recoveries were slightly lower than the first quarter of 2024, but in line with expectations despite lower grades as the operations improved the regrind circuit constraint and implemented the flotation operational strategy improvements, including reagent selection and dose modification.

Milled copper grades during the first half of 2024 were 26% lower than the second half of 2023 as we continued to draw on stockpiled ore. Copper recoveries were 4% higher for the same period despite the lower grades realized as a result of the aforementioned the flotation strategy improvements, including reagent selection and dose modification.

The benefits of the operational stabilization improvements are expected to continue to be realized throughout 2024. We are also accelerating engineering studies to debottleneck and increase the nominal plant capacity to 50,000 tonnes per day earlier than was contemplated in the technical report.

Production and Sales Performance

During the second quarter of 2024, production of copper, gold and silver was 6,719 tonnes, 4,454 ounces and 77,227 ounces, respectively. Production of copper was slightly lower than the first quarter of 2024 primarily as a result of lower head grades from the use of stockpiled ore to feed the mill. Gold production was consistent with the first quarter of 2024.

---

The first half of 2024 production of copper, gold and silver was 13,743 tonnes, 8,871 ounces and 165,603 ounces, respectively.

Cost Performance

Combined mine, mill and G&A unit operating costs in the second quarter of 2024 were  C$19.65 per tonne milled, 17% lower than the first quarter of 2024 primarily due to lower mining costs as there were high ore rehandling costs in the first quarter of 2024. Combined unit operating costs are expected to decrease over time as we continue to implement our stabilization and optimization initiatives at Copper Mountain. As the hiring and training of additional haul truck drivers continues, we expect to have a fully trained complement of truck drivers in August to support the larger mining fleet, which is expected to increase material moved and reduce unit operating costs.

Combined mine, mill and G&A unit operating costs for the first half of 2024 were C$21.65 per tonne milled.

Cash cost and sustaining cash cost per pound of copper produced, net of by-product credits, in the second quarter of 2024 were $2.67 and $5.56, respectively. Cash costs were lower than the first quarter of 2024 by 23% for the same reason as mentioned above regarding the unit cost variance. Sustaining cash costs were 15% higher than the first quarter of 2024 mainly as a result of planned higher capitalized stripping costs to unlock the mine potential according to our stabilization plan.

Cash cost and sustaining cash cost per pound of copper produced, net of by-product credits, in the first half of 2024 were $3.09 and $5.20, respectively.

For further information and a detailed reconciliation, please see the discussion under the "Non-IFRS Financial Performance Measures" section of this MD&A.

² Copper Mountain mine results are stated at 100%. Hudbay owns 75% of Copper Mountain mine. As Copper Mountain was acquired on June 20, 2023, there was only included limited production from the Copper Mountain mine during the 10-day stub period. Copper Mountain's operations had no revenues or corresponding cost of sales recorded during the 10-day stub period from the date of acquisition to the end of the second quarter of 2023.

We expect to achieve 2024 production guidance for all metals in British Columbia. Cash cost for the quarter was above the higher end of our 2024 guidance range; however, we expect the full year cash costs to be within the 2024 guidance range.

FINANCIAL REVIEW

Financial Results

In the second quarter of 2024, we recorded net loss attributable to owners of $16.6 million compared to net loss on the same basis of $14.9 million in the second quarter of 2023, representing an increase in net loss attributable to owners of $1.7 million. Year-to-date in 2024, we recorded net earnings attributable to owners of $5.8 million compared to a net loss on the same basis of $9.5 million for the same period in 2023, representing an increase earnings attributable to owners of $15.3 million.

Revenue

Revenue for the second quarter of 2024 was $425.5 million, $113.3 million higher than the same period in 2023, primarily as a result of higher copper price, gold price and higher gold sales volumes partially offset by lower copper and zinc sales volume due to higher volume of copper concentrate sold in the second quarter of 2023 to reduce the buildup of copper concentrate inventories due to social unrest in Peru during the first quarter of 2023. The acquisition of Copper Mountain mine contributed incremental revenue of $78.1 million during the second quarter of 2024.

Revenue for the first half of 2024 was $950.5 million, $343.1 million higher than the same period in 2023, mainly due to the same factors affecting the quarter-to-date variances described above as well as higher copper sales volume. The acquisition of Copper Mountain mine contributed incremental revenue of $146.0 during the first half of 2024.

¹ Pricing and volume adjustments represents mark-to-market adjustments on provisionally prices sales, realized and unrealized changes to fair value for non-hedge derivative contracts (QP hedges)  and adjustments to originally invoiced weights and assays.

For further detail on variable consideration adjustments, refer to note 18 of our consolidated interim financial statements.

Realized sales prices

This measure is intended to enable management and investors to understand the average realized price of metals sold to third parties in each reporting period. The average realized price per unit sold does not have any standardized meaning prescribed by IFRS, is unlikely to be comparable to similar measures presented by other issuers and should not be considered in isolation or a substitute for measures of performance prepared in accordance with IFRS.

For sales of copper, zinc, gold and silver we may enter into non-hedge derivatives ("QP hedges") which are intended to manage the provisional pricing risk arising from quotational period terms in concentrate sales agreements. The gains and losses on QP hedges are included in the calculation of realized prices. We expect that gains and losses on QP hedges will offset provisional pricing adjustments on concentrate sales contracts.

Our realized prices for the second quarter of 2024 and 2023, respectively, are summarized below:

			Realized prices1 for the			Realized prices1 for the
			Three months ended			Six months ended
Prices		LME QTD 20242	Jun. 30, 2024	Jun. 30, 2023	LME YTD 20232	Jun. 30, 2024	Jun. 30, 2023

Silver3	$/oz		27.13	21.45		23.68	21.75

¹ Realized prices exclude refining and treatment charges and are on the sale of finished metal or metal in concentrate. Realized prices include the effect of provisional pricing adjustments on prior period sales.

² London Metal Exchange average for Cash copper and zinc prices.

³ Sales of gold and silver from Constancia mine are subject to our precious metals stream agreement with Wheaton, pursuant to which we recognize deferred revenue for precious metals deliveries and also receive cash payments. Stream sales are included within realized prices and their respective deferred revenue and cash payment rates can be found on page 36 of this MD&A.

---

In addition to QP hedges, we may periodically undertake metal price hedging in accordance with Board approved policies to achieve strategic objectives, including locking in favourable metal prices to ensure minimum cash flows during or after the construction of a mine or during a period of reduced liquidity, to manage cash flows at shorter life or higher cost operations or as part of a financing arrangement. The realized prices, denoted in the table above, exclude the impact of derivative mark-to-market gains and losses on these non-QP hedges, which are included in change in fair value of financial instruments in our consolidated interim statement of earnings. As of June 30, 2024, Hudbay had the following non-QP hedges outstanding:

- Forward sales contracts at the Copper Mountain mine for a total of 13.2 million pounds of copper over the period of July 2024 to April 2025 at an average price of $3.95 per pound;

- Zero-cost collar program at the Copper Mountain mine for 16.5 million pounds of copper over a twelve month period of July 2024 to April 2025 at an average floor price of $3.88 per pound and an average cap price of $4.14 per pound; and

- Zero-cost collar program for 5,000 ounces of gold production per month over a period of July 2024 to December 2024 at an average floor price of $2,110 per ounce and an average cap price of $2,467 per ounce.

The forward copper sales and zero copper cost collar hedges were entered into in the first quarter of 2024, which represent a total of approximately 44% of Copper Mountain's expected 2024 production.

¹ As Copper Mountain was acquired on June 20, 2023, there were no comparative figures for the three and six months ended June 30, 2023.

Total cost of sales for the second quarter of 2024 was $347.9 million, reflecting an increase of $58.6 million from the second quarter of 2023 in part due to $75.8 million of operating costs from British Columbia with no similar costs in the comparative period. In addition, Peru cost of sales decreased by $34.9 million in the second quarter of 2024, compared to the same period of 2023 mainly due to lower drawdown of product inventory versus the comparative 2023 period and lower depreciation, in line with the higher production during the quarter. Manitoba cost of sales increased by $17.7 million in the second quarter of 2024, primarily as a result of higher mining costs and higher G&A and freight costs during the quarter, compared to the same period of 2023.

Total cost of sales for the first half of 2024 was $720.9 million, reflecting an increase of $202.9 million from the same period in 2023 in part due to $144.4 million of incremental operating costs from British Columbia with no similar comparative period. Peru cost of sales increased by $31.6 million mainly due to higher G&A and freight costs and higher depreciation. Manitoba cost of sales increased by $26.9 million as a result of the same factors affecting quarter-to-date variance described above.

For details on unit operating costs, refer to the respective tables in the "Operations Review" section of this MD&A.

For the second quarter of 2024, other significant variances in non-operating expenses, compared to the same period in 2023, include the following:

- Net finance expenses increased by $13.8 million primarily due to an increase in mark-to-market losses of $11.0 million from non-QP hedges and $3.1 million increase in the relative revaluation loss of the gold prepayment liability partially offset by a decrease in the accretion of revenue streaming arrangement of $0.6 million.

- Selling and administrative expenses increased by $9.8 million reflecting a higher share-based compensation expense as a result of a comparative increase in share price during the current period along with incremental selling and administrative expenses incurred by the Copper Mountain mine.

- Other expenses decreased by $2.7 million primarily due to $6.8 million of lower acquisition costs related to the acquisition of Copper Mountain incurred in 2023 and $0.9 million lower care and maintenance costs for Manitoba partially offset by an increase of $3.4 million in amortization of certain community costs and an additional $1.2 million of loss on disposition of PP&E.

- Re-evaluation adjustment - environmental provision gain decreased by $2.0 million due to the relative revaluation of the environmental reclamation provision on our Manitoba non-producing sites from changes in long term risk-free discount rates and inflation rates.

Given the long term nature of the reclamation cash flows, the related environmental reclamation provision is highly sensitive to changes in inflation rates and long-term risk-free discount rates and, as such, we may continue to experience significant quarterly environmental reclamation provision revaluations. 

For the year-to-date 2024, other significant variances in non-operating expenses, compared to the same period in 2023, included the following:

- Net finance expenses increased by $22.8 million due to an increase in market-to-market loss of $14.3 million from non-QP hedges, $5.2 million increase in net foreign exchange loss, $4.0 million increase in other finance expenses and $2.8 million increase in interest expense on long-term debt partially offset by decrease in the accretion for revenue streaming arrangement of $1.1 million.

- Selling and administrative expenses increased by $17.3 million due to the same reasons as outlined above in the quarterly variance analysis.

- Other expenses increased by $8.6 million primarily due an increase of $10.1 million in write-off of previously capitalized PP&E costs, net of capitalized accrued interest, primarily related to an expired option agreement in Arizona and a $4.8 million increase in amortization of certain community costs, partially offset by $6.8 million of lower acquisition costs related to the acquisition of Copper Mountain incurred in 2023.

- Exploration expenses increased by $5.0 million primarily due to our planned Snow Lake exploration program consisting of modern geophysical programs and multi-phased drilling campaigns.

- Re-evaluation adjustment - environmental provision gain decreased by $5.0 million due to the same reasons as outlined above in the quarterly variance analysis.

Tax Expense

For the three and six months ended June 30, 2024, tax expense increased by $36.6 million and $73.9 million compared to the same periods in 2023. The following table provides further details:

(in $ thousands)		Three months ended						Six months ended
		Jun. 30, 2024			Jun. 30, 2023			Jun. 30, 2024			Jun. 30, 2023

¹ Deferred tax expense (recovery) represents our draw down/increase of non-cash deferred income and mining tax assets/liabilities.

Income Tax Expense/Recovery

Applying the estimated Canadian statutory income tax rate of 26.2% to our earnings before taxes of $68.2 million for the year-to-date of 2024 would have resulted in a tax expense of approximately $17.9 million; however, we recorded an income tax expense of $50.6 million. The significant items causing our effective income tax rate to be different than the 26.2% estimated Canadian statutory income tax rate include:

- Deductible temporary differences with respect to Peru, Manitoba and British Columbia, relating to the decommissioning and restoration liabilities, were derecognized as we have determined that it is not probable that we will realize the recovery of these deferred tax assets based on the timing of the reversals of the deductible temporary differences and the future projected taxable earnings of the operations. This resulted in a combined deferred tax expense of $5.7 million.

- Foreign exchange on the translation of deferred tax balances to group currency resulted in a deferred tax expense of $9.7 million.

- The tax expense with respect to our foreign operations are recorded using an income tax rate other than the Canadian statutory income tax rate of 26.2%, resulting in a tax expense of $13.0 million.

- New Canadian tax legislation, applicable to Hudbay starting in the 2024 tax year, that limits interest and finance expenses to 30% of Tax EBITDA. The restricted interest and finance expense (RIFE) in the year creates a new tax pool that can be used in future years when there is excess capacity available. The effect of restricted interest and financing expense limitations of which no deferred tax asset is recognized results in a tax expense of $7.0 million.

- The effect of expenditures renounced to flow through share investors that would otherwise have been deductible for tax purposes resulted in a tax expense of $2.5 million.

Mining Tax Expense

We recorded $19.4 million of mining tax expense for year-to-date of 2024. Effective mining tax rates can vary significantly based on the composition of our earnings and the expected amount of mining taxable earnings. Corporate costs and other costs not related to mining operations are not deductible in computing mining taxable earnings. A brief description of how mining taxes are calculated in our various business units is discussed below.

Manitoba

The Province of Manitoba imposes mining tax on earnings related to the sale of mineral products mined in the Province of Manitoba (mining taxable profit) at the following rates:

- 10% of total mining taxable earnings if mining profit is C$50 million or less;

- Between mining earnings of C$50 and $C55 million, mining tax is equal to a minimum of C$5 million plus mining earnings less C$50 million multiplied by 65%;

- 15% of total mining taxable earnings if mining profits are between C$55 million and C$100 million;

---

- Between mining earnings of C$100 million and C$105 million, mining tax is equal to a minimum of C$15 million plus mining earnings less C$100 million multiplied by 57%; and

- 17% of total mining taxable earnings if mining profits exceed C$105 million.

We estimate that the tax rate that will be applicable when temporary differences reverse will be approximately 10.0%.

Peru

The Peruvian government imposes two parallel mining tax regimes, the Special Mining Tax and the Modified Royalty, on companies' operating mining income on a sliding scale, with progressive rates ranging from 2.0% to 8.4% and 1.0% to 12.0%, respectively. Based on financial forecasts, we have recorded a deferred tax liability as at June 30, 2024, at the tax rate we expect to apply when temporary differences reverse.

British Columbia

The Province of British Columbia imposes a 13% net revenue tax on the sale of mineral products mined in the province of British Columbia after the mine owner has recovered the capital invested in the mine and its "Cumulative Expenditure Account" ("CEA") no longer has a balance. The tax is paid on the profit in excess of the capital that has been invested in the mine. British Columbia mineral tax is deductible for federal and provincial income tax purposes.

While there is a balance in the CEA account, the mine owner must pay a "Net Current Proceeds" ("NCP") tax of 2%. Any amounts paid as NCP can then be claimed in the future against net revenue taxes payable.

We estimate that the effective tax rate that will be applicable when temporary differences reverse will be approximately 9.49%.

LIQUIDITY AND CAPITAL RESOURCES

As at June 30, 2024, our liquidity includes $483.8 million in cash, $40.0 million in short-term investments as well as undrawn total availability of $424.7 million under our revolving credit facilities.

Equity Bought Deal

On May 24, 2024, we successfully completed an equity offering, for a total of 42,366,000 common shares of Hudbay at a price of $9.50 per common share, which generated net proceeds of $386.2 million, net of transaction and share issuance costs. The equity offering was completed pursuant to an underwriting agreement dated May 22, 2024 entered into between the Company and a syndicate of underwriters.

Senior Unsecured Notes

During the second quarter, we purchased $11.6 million of our 4.5% senior notes due April 2026 ("2026 Notes") and $22.5 million of our 6.125% senior notes due April 2029 ("2029 Notes") on the open market. As at June 30, 2024, we had $588.4 million aggregate principal amount of 2026 Notes and $577.5 million aggregate principal amount of 2029 Notes. From July 1 to August 12, 2024, we purchased an additional $13.4 million and $35.1 million of our 2026 and 2029 Notes, respectively, through an automatic purchase program.

Senior Secured Revolving Credit Facilities

We have two senior secured revolving credit facilities with total commitments of $450 million ("the Credit Facilities") for our Canadian and Peruvian businesses on substantially similar terms and conditions.

During the second quarter of 2024, we fully repaid the $90.0 million of debt outstanding under our Peruvian revolving credit facility.

As at June 30, 2024, we were in compliance with our covenants under the Credit Facilities and had also drawn $25.3 million in letters of credit under the Credit Facilities.

---

C$130 Million Bilateral Letter of Credit Facility

We have a C$130.0 million bilateral letter of credit facility ("LC Facility") with a major Canadian financial institution. The LC Facility has no financial covenants and enables us to issue up to C$130.0 million of letters of credit to beneficiaries on an unsecured basis at attractive rates, including C$30.0 million sub-limit for financial letters of credit. As at June 30, 2024, the Manitoba business unit had drawn $55.4 million in letters of credit under the LC Facility.

Surety Bonds and Letters of Credit

As at June 30, 2024, the Arizona business unit had $8.7 million in surety bonds issued to support future reclamation and closure obligations and the Peru business unit had $126.3 million in letters of credit issued with various Peruvian financial institutions to support future reclamation and other operating matters. In addition, the British Columbia business unit had $48.0 million in surety bonds issued to support future reclamation and $4.8 million in surety bonds issued to support the hydro used at Copper Mountain mine. The British Columbia business unit also had $2.3 million in letter of credit issued with various Canadian financial institutions related to other operating matters, cash collateral of $2.3 million was posted under these letters of credit.

Gold Prepayment Liability

During the fourth quarter of 2020, we entered into a gold forward sale and prepay transaction which generated $115.0 million in cash proceeds to pre-fund the expected capital requirements for the New Britannia gold mill refurbishment project. The transaction valued the future gold ounce delivery obligation at 79,954 gold ounces to be delivered in fixed monthly deliveries of 3,331 gold ounces over a 24-month period from January 2022 to December 2023.

During the first quarter of 2023, we amended our gold forward sale and prepay agreements to defer eight months of deliveries starting with February 2023. As at June 30, 2024 we have 6,881 ounces of gold fixed monthly deliveries to make from July to August 2024. The fair value of the financial liability as at June 30, 2024 was $15.9 million.

Working Capital

Working capital increased by $287.9 million to $423.8 million from December 31, 2023 to June 30, 2024, primarily due to an increase in cash and cash equivalents of $234.0 million, an increase in short-term investment of $40.0 million, a decrease in gold prepayment liability of $40.0 million, a decrease in trades and other payable of $13.1 million, a decrease in deferred revenue of $6.3 million, an increase in prepaid and other expenses of $6.4 million, a decrease in taxes payable of $2.7 million, and increase in other financial assets of $3.9 million. Partially offsetting these items were a decrease in inventories of $21.5 million, a decrease in trade receivables and taxes receivables of $22.1 million and an increase in other liabilities, other financial liabilities and lease liabilities of $14.9 million.

Cash Flows

The following table summarizes our cash flows for the three and six months ended June 30, 2024 and June 30, 2023:

(in $ thousands)		Three months ended						Six months ended
		Jun. 30, 2024			Jun. 30, 2023			Jun. 30, 2024			Jun. 30, 2023

Cash Flow from Operating Activities

Cash generated from operating activities was $138.5 million during the second quarter of 2024, an increase of $113.9 million compared to the same period in 2023. Operating cash flow before change in non-cash working capital was $122.0 million during the second quarter of 2024, reflecting an increase of $66.1 million compared to the second quarter of 2023. The increase in operating cash flows before change in working capital was primarily the result of higher copper and gold sales volumes in part due to higher gold and copper grade zones at Lalor, higher realized gold metal prices as well as incremental contribution margin from the Copper Mountain mine. This was partially offset by a significant increase in cash taxes paid of $21.6 million mainly at our Peru operations, compared to the same period in 2023.

Year-to-date cash generated from operating activities was $278.2 million in 2024, an increase of $182.3 million compared to 2023. Operating cash flow before changes in non-cash working capital for the first half of 2024 was $269.6 million, an increase of $128.1 million compared to 2023. The increase in operating cash flow before changes in working capital is mostly attributable to the same reasons as outlined above in the quarterly variance.

Cash Flow from Investing and Financing Activities

During the second quarter of 2024, we generated $62.2 million in investing and financing activities, primarily driven by $386.2 million of proceeds from equity issuance, net of transaction and issuance costs, $2.9 million of interest income received and $1.1 million net proceeds from exercise of stock options and warrants. These cash inflows were partially offset by $90.0 million in repayments on our revolving credit facilities, $89.5 million in capital expenditures, $40.0 million in short-term investments, $33.8 million of our senior unsecured notes repurchased, net of discount, $32.4 million in interest paid on our long-term debt, a $24.0 million repayment of our gold prepayment liability, $10.5 million in capitalized lease and equipment financing payments, $5.3 million in other financing costs mainly related to our Credit Facilities and withholding taxes and $2.6 million in community agreement payments.

Year-to-date, we spent $44.3 million in investing and financing activities, primarily driven by $151.9 million in capital expenditures, $100.0 million in repayments on our revolving credit facilities, $45.4 million repayment of our gold prepayment liability, $40.0 million in short-term investments, $33.8 million of our senior unsecured notes repurchased, net of discount, $33.3 million in interest paid on our long-term debt,  $19.1 million in capitalized lease and equipment financing payments, $10.6 million in other financing costs mainly related to our Credit Facilities and withholding taxes, $4.0 million in community agreement payments and $2.6 million of dividends paid. These cash outflows were partially offset by $386.2 million of proceeds from equity issuance, net of transaction and issuance costs, $7.7 million of interest income and grants received and $2.4 million net proceeds from exercise of stock options and warrants.

¹ Peru sustaining capital expenditures include capitalized stripping costs.

² Other capitalized costs primarily include right-of-use lease and equipment financing additions, which are excluded from guidance in 2024, in addition to non-cash deferred stripping.

³ British Columbia operations represented on a 100% basis and for the period since the acquisition completion date of June 20, 2023. Hence, there are no comparatives figures for the three and six months ended June 30, 2023.

For the three and six months ended June 30, 2024, total capital additions increased by $49.3 million and $67.0 million, respectively, compared to the same period in 2023, primarily due to new sustaining capital expenditures at the Copper Mountain mine and higher capitalized right of use assets and leases, partially offset by reduced sustaining and growth capital expenditures in Manitoba and Peru.

Sustaining capital expenditures in Manitoba for the three and six months ended June 30, 2024 were $14.6 million and $24.3 million, respectively, representing an increase of $2.1 million and $0.2 million, respectively, compared to the same period in 2023 due to increased mobile equipment spending at Lalor and purchase of external crusher equipment at Stall, partially offset by lower capital development at Lalor in the period. Sustaining capital expenditures in Peru for the three and six months ended June 30, 2024 were $29.5 million and $54.7 million, respectively, representing an increase of $0.8 million and a decrease of $3.1 million, respectively, compared to the same period in 2023. Sustaining capital expenditures in British Columbia for the three and six months ended June 30, 2024 were $36.9 million and $53.2 million, respectively, which included $19.7 million and $30.4 million of capitalized stripping related to our three year accelerated stripping campaign to access higher grade ore. The accelerated stripping campaign in British Columbia is expected to improve operating efficiencies and lower unit operating costs over the next three years.

---

Growth capital spending in Manitoba for the three and six months ended June 30, 2024 were $1.6 million and $3.3 million, respectively, representing a decrease of $3.5 million and $10.2 million, respectively, compared to the same period in 2023. The decrease mainly relates to the completion of the Stall mill recovery improvement project in 2023, partially offset by the execution of exploration at 1901 in 2024. Growth capital expenditures in Peru for the three and six months ended June 30, 2024 were $0.1 million and $0.2 million, respectively representing a decrease of $9.8 million and $11.5 million, respectively, compared to the same period in 2023. The decrease mainly relates to the completion of the copper recovery improvement project in 2023. Arizona's capital expenditures for the three and six months ended June 30, 2024 were $5.4 million and $9.8 million, respectively, mainly relate to ongoing carrying costs.

Other capitalized costs for the three and six months ended June 30, 2024 were $27.8 million and $46.2 million, respectively which are mostly made up of non-cash capitalized lease and equipment financing additions.

Capitalized exploration for the three and six months ended June 30, 2024 were $2.0 million and $4.1 million, respectively.

Capital Commitments

As at June 30, 2024, we had outstanding capital commitments in Canada of approximately $19.3 million, of which $7.2 million can be terminated, approximately $63.1 million in Peru primarily related to sustaining capital commitments and exploration option agreements, all of which can be terminated, and approximately $34.5 million in Arizona, primarily related to our Copper World project, none of which can be terminated.

² Annual consolidated results may not calculate based on amounts presented in this table due to rounding.

On a quarterly basis, the Company's revenue is primarily impacted by metal prices, production mix and sales volumes of the key metals we produce. In addition to these factors, gross profit, net earnings (loss) attributable, earnings (loss) per share attributable, operating cash flow before change in non-cash working capital and adjusted EBITDA are also impacted by input costs. Net earnings (loss) and earnings (loss) per share are further impacted by net finance expense and re-evaluation adjustments of our closed site environmental provision.

The Company's results have also been impacted by the acquisition of Copper Mountain in June 2023.

During the second quarter of 2024, realized copper and gold prices continue to climb which overcame the decline in sales volumes of concentrate compared to the first quarter of 2024. Expected lower mined grades observed for the same metals in Peru and Manitoba were the primary factor for the decline in production since the first quarter of the year. Cost control remained favourable as we continued to track within cost guidance given the expected cadence in the year's production profile. Higher mining taxes continued as we experienced higher profitability over the past several quarters. Lastly, volatile inter-period copper and gold prices led to relatively high mark-to-market adjustments for our strategic non-QP hedging program and high share prices for our common shares led to higher share-based compensation expenses. This led to a total of $19.5 million in mark-to-market adjustments to be added back in our adjusted net earnings - attributable to owners measure.

The first quarter of 2024 and the fourth quarter of 2023 reflected the continuation of strong copper, gold and silver production that commenced in the third quarter of 2023. The increase in copper, gold and silver prices in the first quarter of 2024 also contributed to strong revenue and profitability in the quarter.

Third quarter of 2023 results reflected significantly higher copper and gold production and sales volumes from the high grade zones of the Pampacancha deposit and higher gold and copper grade zones at Lalor resulting in a significant increase in our revenues, gross profits and earnings.

The second quarter of 2023 benefited from the drawdown of higher-than-normal unsold copper concentrate inventory levels in Peru that had built up due to supply chain disruptions during a short period of social and political unrest in the first quarter of 2023.

Gold prices during the first quarter of 2023 averaged levels not seen since 2020, which positively impacted gross profit during the quarter. Social and political unrest in Peru resulted in road blockades causing logistics and supply chain disruptions until mid-February 2023 and led to a buildup of copper concentrate inventory above normal operating levels, affecting overall revenues and net earnings attributable in the first quarter.

Revenues for the fourth quarter of 2022 were negatively impacted by lower production due to planned maintenance programs at Lalor and Constancia, short-term changes in the mine plan in Peru and a build up of product inventory in Peru due to the aforementioned social unrest. The revenue impact of lower throughput was partially offset by higher commodity prices. Inflationary pressures on fuel, consumables and energy costs negatively impacting our production costs and margins.

Commodity prices declined during the third quarter of 2022 while growing inflationary pressures contributed to higher mine operating costs resulting in declines in our key financial metrics during the quarter.

NON-IFRS FINANCIAL PERFORMANCE MEASURES

Adjusted net earnings (loss) attributable to owners, adjusted net earnings (loss) per share attributable to owners, adjusted EBITDA, realized prices, net debt, net debt to adjusted EBITDA, cash cost, sustaining and all-in sustaining cash cost per pound of copper produced, cash cost and sustaining cash cost per ounce of gold produced, combined unit cost and ratios based on these measures are non-IFRS performance measures. These measures do not have a meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other issuers. These measures should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS and are not necessarily indicative of gross profit or cash flow from operations as determined under IFRS. Other companies may calculate these measures differently.

Management believes adjusted net earnings (loss) attributable to owners and adjusted net earnings (loss) per share attributable to owners provides an alternate measure of the Company's performance for the current period and gives insight into its expected performance in future periods. These measures are used internally by the Company to evaluate the performance of its underlying operations and to assist with its planning and forecasting of future operating results. As such, the Company believes these measures are useful to investors in assessing the Company's underlying performance. We provide adjusted EBITDA to help users analyze our results and to provide additional information about our ongoing cash generating potential in order to assess our capacity to service and repay debt, carry out investments and cover working capital needs. Net debt is shown because it is a performance measure used by the Company to assess our financial position. Net debt to adjusted EBITDA is shown because it is a performance measure used by the Company to assess our financial leverage and debt capacity. Realized price is shown to understand the average realized price of metals sold to third parties in each reporting period. Cash cost, sustaining and all-in sustaining cash cost per pound of copper produced are shown because we believe they help investors and management assess the performance of our operations, including the margin generated by the operations and the Company. Cash cost and sustaining cash cost per ounce of gold produced are shown because we believe they help investors and management assess the performance of our Manitoba operations. Combined unit cost is shown because we believe it helps investors and management assess our cost structure and margins that are not impacted by variability in by-product commodity prices.

Adjusted Net Earnings - Attributable

Adjusted net earnings attributable to owners represents net earnings (loss) excluding certain impacts such as mark-to-market adjustments, foreign exchange (gains) loss, revaluation adjustment - environmental provisions for closed sites, variable consideration adjustment related to stream agreements, impairment charges and reversal of impairment charges on assets, (gain) loss on disposal of assets, other items that are not indicative of the underlying operating performance of our core business; and tax effect and non-controlling interest of the previously discussed items. These measures are not necessarily indicative of net earnings (loss) as determined under IFRS. The following table provides a reconciliation of net earnings and non-controlling interest per the condensed consolidated interim statements of loss, to adjusted net earnings attributable to owners of the Company for the three and six months ended June 30, 2024 and 2023.

Adjusted EBITDA

Adjusted EBITDA is earnings before net finance expense/income, tax expense/recoveries, depreciation and amortization of property, plant and equipment and deferred revenue, as well as certain other adjustments. We calculate adjusted EBITDA by excluding certain adjustments included within our adjusted net earnings attributable measure which we believe reflects the underlying performance of our core operating activities. The measure also removes the impact of non-cash items and financing costs that are not associated with measuring the underlying performance of our operations. However, our adjusted EBITDA is not the measure defined as EBITDA under our senior notes or revolving credit facilities and may not be comparable with performance measures with the same name reported by other companies. Adjusted EBITDA should not be considered as a substitute for earnings or as a better measure of liquidity than operating cash flow, which are calculated in accordance with IFRS. We provide adjusted EBITDA to help users analyze our results and to provide additional information about our ongoing cash generating potential in order to assess our capacity to service and repay debt, carry out investments and cover working capital needs.

Cash Cost, Sustaining and All-in Sustaining Cash Cost (Copper Basis)

Cash cost per pound of copper produced ("cash cost") is a non-IFRS measure that management uses as a key performance indicator to assess the performance of our operations. Our calculation designates copper as our primary metal of production as it has been the largest component of revenues. The calculation is presented in four manners:

- Cash cost, before by-product credits - This measure is gross of by-product revenues and is a function of the efforts and costs incurred to mine and process all ore mined. However, the measure divides this aggregate cost over only pounds of copper produced, our primary metal of production. This measure is generally less volatile from period to period, as it is not affected by changes in the price received for by-product metals. It is, however, affected by the relative mix of copper concentrate and zinc concentrate production, where an increase in production of zinc concentrate will tend to result in an increase in cash cost under this measure.

- Cash cost, net of by-product credits - In order to calculate the net cost to produce and sell copper, the net of by-product credits measure subtracts the revenues realized from the sale of the metals other than copper. The by-product revenues from zinc, gold, and silver are significant and are integral to the economics of our operations. The economics that support our decision to produce and sell copper would be different if we did not receive revenues from the other significant metals being extracted and processed. This measure provides management and investors with an indication of the minimum copper price consistent with positive operating margins, assuming realized by-product metal prices are consistent with those prevailing during the reporting period. It also serves as an important operating statistic that management and investors utilize to measure our operating performance versus that of our competitors. However, it is important to understand that if by-product metal prices decline alongside copper prices, the cash cost net of by-product credits would increase, requiring a higher copper price than that reported to maintain positive cash flows and operating margins.

---

- Sustaining cash cost, net of by-product credits - This measure is an extension of cash cost that includes cash sustaining capital expenditures, including payments on capitalized leases, capitalized sustaining exploration, net smelter returns royalties, payments on certain long-term community agreements, as well as accretion and amortization for expected decommissioning activities for producing assets. It does not include corporate selling and administrative expenses. It provides a more fulsome measurement of the cost of sustaining production than cash cost, which is focused on operating costs only.

- All-in sustaining cash cost, net of by-product credits - This measure is an extension of sustaining cash cost that includes corporate G&A, regional costs, accretion and amortization for community agreements relating to current operations, and accretion for expected decommissioning activities for non-producing sites. Due to the inclusion of corporate selling and administrative expenses, all-in sustaining cash cost is presented on a consolidated basis only.

The tables below present a detailed build-up of cash cost and sustaining cash cost, net of by-product credits, by business unit in addition to consolidated all-in sustaining cash cost, net of by-product credits, and reconciliations between cash cost, net of by-product credits, to the most comparable IFRS measures of cost of sales for the three and six months ended June 30, 2024 and 2023. Cash cost, net of by-product credits may not calculate exactly based on amounts presented in the tables below due to rounding.

Gold Cash Cost and Gold Sustaining Cash Cost

Cash cost per ounce of gold produced ("gold cash cost") is a non-IFRS measure that management uses as a key performance indicator to assess the performance of our Manitoba operations. This alternative cash cost calculation designates gold as the primary metal of production as it represents a substantial component of revenues for our Manitoba business unit and should therefore be less volatile over time than Manitoba cash cost per pound of copper. The calculation is presented in three manners:

- Gold cash cost, before by-product credits - This measure is gross of by-product revenues and is a function of the efforts and costs incurred to mine and process all ore mined. However, the measure divides this aggregate cost over only ounces of gold produced, the assumed primary metal of production. This measure is generally less volatile from period to period, as it is not affected by changes in the price received for by-product metals.

- Gold cash cost, net of by-product credits - In order to calculate the net cost to produce and sell gold, the net of by-product credits measure subtracts the revenues realized from the sale of the metals other than gold. The by-product revenues from copper, zinc, and silver are significant and are integral to the economics of our Manitoba operation. The economics that support our decision to produce and sell gold would be different if we did not receive revenues from the other significant metals being extracted and processed. This measure provides management and investors with an indication of the minimum gold price consistent with positive operating margins, assuming realized by-product metal prices are consistent with those prevailing during the reporting period. It also serves as an important operating statistic that management and investors utilize to measure our operating performance at our Manitoba operation versus that of our competitors. However, it is important to understand that if by-product metal prices decline alongside gold prices, the gold cash cost net of by-product credits would increase, requiring a higher gold price than that reported to maintain positive cash flows and operating margins.

- Gold sustaining cash cost, net of by-product credits - This measure is an extension of gold cash cost that includes cash sustaining capital expenditures, capitalized exploration, net smelter returns royalties, as well as accretion and amortization for expected decommissioning activities for producing assets. It does not include corporate selling and administrative expenses. It provides a more fulsome measurement of the cost of sustaining production than gold cash cost, which is focused on operating costs only.

The tables below present a detailed build-up of gold cash cost and gold sustaining cash cost, net of by-product credits, for the Manitoba business unit, and reconciliations between gold cash cost, net of by-product credits, to the most comparable IFRS measures of cost of sales for the three and six months ended June 30, 2024 and 2023. Gold cash cost, net of by-product credits, may not calculate exactly based on amounts presented in the tables below due to rounding.

Combined Unit Cost

Combined unit cost ("unit cost") and zinc plant unit cost is a non-IFRS measure that management uses as a key performance indicator to assess the performance of our mining and milling operations. Combined unit cost is calculated by dividing the cost of sales by mill throughput. This measure is utilized by management and investors to assess our cost structure and margins and compare it to similar information provided by other companies in our industry. Unlike cash cost, this measure is not impacted by variability in by-product commodity prices since there are no by-product deductions; costs associated with profit-sharing and similar costs are excluded because of their correlation to external metal prices. In addition, the unit costs are reported in the functional currency of the operation which minimizes the impact of foreign currency fluctuations. In all, the unit cost measures provide an alternative perspective on operating cost performance with minimal impact from external market prices.

The tables below present a detailed combined unit cost for the Peru and Manitoba business units, and reconciliations between these measures to the most comparable IFRS measures of cost of sales for the three and six months ended June 30, 2024 and 2023.

Estimates and judgements

The preparation of the consolidated interim financial statements in accordance with IFRS requires us to make judgements, estimates and assumptions that affect the application of accounting policies, reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated interim financial statements, and reported amounts of revenue and expenses during the reporting period. Actual results may differ from these estimates.

We review these estimates and underlying assumptions on an ongoing basis based on our experience and other factors, including expectations of future events that we believe to be reasonable under the circumstances. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected. Certain accounting estimates and judgements have been identified as being "critical" to the presentation of our financial condition and results of operations because they require us to make subjective and/or complex judgments about matters that are inherently uncertain; or there is a reasonable likelihood that materially different amounts could be reported under different conditions or using different assumptions and estimates.

For more information on judgements and estimates, refer to note 2 of our June 30, 2024 consolidated interim financial statements.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

Management is responsible for establishing and maintaining adequate internal control over financial reporting ("ICFR"). ICFR is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated interim financial statements for external purposes in accordance with IFRS.

After the closing of the Copper Mountain acquisition on June 20, 2023, management determined to temporarily limit the scope of design of disclosure controls and procedures ("DC&P") and ICFR to exclude controls, policies and procedures of Copper Mountain. This scope of limitation was permitted in accordance with section 3.3(1)(b) of NI 52-109 and SEC staff guidance, which allows for an issuer to limit the design of DC&P or ICFR to exclude a business that the issuer acquired not more than 365 days before the end of the financial period to which the Chief Executive Officer's and Chief Financial Officer's certification of interim filings relate. As of June 20, 2024, this temporary limitation ceased to apply and, as of such date, the controls, policies and procedures in respect of Copper Mountain were no longer excluded from the scope of design of our DC&P and ICFR.

We did not make any changes to ICFR during the interim period ended June 30, 2024 that materially affected or are reasonably likely to materially affect our ICFR.

Hudbay Announces Second Quarter 2024 Results; Production Guidance Reaffirmed and Cash Cost Guidance Improved

Toronto, Ontario, August 13, 2024 - Hudbay Minerals Inc. ("Hudbay" or the "company") (TSX, NYSE: HBM) today released its second quarter 2024 financial results. All amounts are in U.S. dollars, unless otherwise noted. All production and cost amounts reflect the Copper Mountain mine on a 100% basis, with Hudbay owning a 75% interest in the mine.

"The continued execution of our operational plans in the second quarter has positioned us well to achieve our 2024 production guidance, and our exposure to gold by-products and strong cost control have allowed us to improve our 2024 cash cost guidance," said Peter Kukielski, President and Chief Executive Officer. "Our strong and diversified operating base continues to generate free cash flow driven in part by efficient milling performance in Peru and Manitoba. We are also continuing to execute our British Columbia stabilization plans and planned stripping programs in Peru and British Columbia to unlock higher copper and gold grades in the near-term. This has led to robust EBITDA generation over the past 12 months, which together with our recent successful equity offering, has allowed us to significantly accelerate our deleveraging efforts and transform our balance sheet. We are now even better positioned to continue to advance our many growth initiatives to unlock significant upside potential in our pipeline and further enhance our copper and gold exposure."

Delivered In-line Second Quarter Operating and Financial Results; Production Guidance Reaffirmed and Cash Cost Guidance Improved

• Achieved consolidated copper production of 28,578 tonnes and gold production of 58,614 ounces in the second quarter of 2024, in line with quarterly production cadence expectations for 2024.
• Enhanced operating platform delivered a 32% increase in copper production and a 20% increase in gold production over the second quarter of 2023ⁱⁱ, reflecting the benefits of a larger diversified operating platform with the addition of Copper Mountain and the continued execution of operational efficiencies across the business.
• Strong cost control with consolidated cash costⁱ and sustaining cash costⁱ per pound of copper produced, net of by-product creditsⁱ, in the second quarter of 2024 of $1.14 and $2.65, respectively, in alignment with the cadence of costs expected in 2024.
• Reaffirmed full year 2024 consolidated production guidance for all metals including 137,000 to 176,000 tonnes of copper and 263,000 to 319,000 ounces of gold as the company expects stronger production in the second half of 2024 in accordance with the mine production profile.
• Improved 2024 annual operating cost guidance with decreased consolidated cash costⁱ guidance range of $0.90 to $1.10 per pound, a result of meaningful exposure to gold by-product credits and continued strong cost control.
• Peru operations continued to benefit from strong mill throughput, averaging approximately 85,000 tonnes per day in the second quarter despite a planned semi-annual mill maintenance shutdown. The Pampacancha stripping program to advance to higher grades later this year is well underway. The reduced mining from Pampacancha resulted in 19,217 tonnes of copper and 10,672 ounces of gold produced in the second quarter of 2024, in line with quarterly cadence expectations. Peru cash cost per pound of copper produced, net of by-product creditsⁱ, in the second quarter was $1.78, an expected increase from the first quarter given lower planned production levels, and a 17% decrease compared to the second quarter of 2023.

---

• Manitoba operations produced 43,488 ounces of gold in the second quarter of 2024 as New Britannia continues to operate well above nameplate capacity and budgeted throughput levels. Manitoba cash cost per ounce of gold produced, net of by-product creditsⁱ, was $771 during the second quarter of 2024, similar to the first quarter, and a decrease of 30% compared to the same quarter last year.
• British Columbia operations produced 6,719 tonnes of copper at a cash cost per pound of copper produced, net of by-product creditsⁱ, of $2.67 in the second quarter. Cash cost improved by 23% over the first quarter, reflecting ongoing operational stabilization efforts as mine stripping activities are accelerated and mill improvement initiatives are underway at Copper Mountain.
• Achieved revenue of $425.5 million and operating cash flow before change in non-cash working capital of $122.0 million in the second quarter of 2024.
• Second quarter net loss attributable to owners and loss per share attributable to owners were $16.6 million and $0.05, respectively. After adjusting for items on a pre-tax basis such as a non-cash gain of $2.7 million related to a quarterly revaluation of the company's closed site environmental reclamation provision, a $10.7 million revaluation loss related to the gold prepayment liability, unrealized strategic gold and copper hedges and investments and a $2.1 million write-down of PP&E, among other items, second quarter adjusted earningsⁱ per share attributable to owners was nil.
• Net loss attributable to owners of $16.6 million in the second quarter was meaningfully impacted by tax expense of $20.8 million despite having earnings before tax of only $0.4 million. The elevated tax expense was due to mining taxes that are calculated based on taxable mining profits in each operating jurisdiction, the limited deductibility of certain expenses and foreign exchange fluctuations on deferred tax balances.
• Adjusted EBITDAⁱ was $145.0 million during the second quarter of 2024.
• Cash and cash equivalents and short-term investments increased by $274.0 million to $523.8 million during the first half of 2024 due to a successful equity offering and strong operating cash flows bolstered by higher copper and gold prices, enabling a $405.9 million reduction in net debtⁱ during the first half of 2024.

Accelerated Deleveraging and Transformed Balance Sheet

• Hudbay's unique copper and gold diversification in Peru and North America provides exposure to higher copper and gold prices and attractive free cash flow generation.
• Achieved trailing 12 month adjusted EBITDAⁱ of $824.3 million, a substantial increase from $407.1 million for the 12 months ending June 30, 2023.
• Completed successful equity offering on May 24, 2024 for gross proceeds of $402.5 million and net proceeds of $386.2 million, net of transaction costs, to accelerate growth and deleveraging.
• Significantly accelerated deleveraging efforts. Repaid all $90.0 million of advances outstanding on the senior secured credit facilities during the second quarter of 2024 and made open market purchases of approximately $34.1 million of the company's senior unsecured notes in June 2024, at a discount. Long-term debt reduced to $1,155.6 million at June 30, 2024 from $1,278.6 million at March 31, 2024.
• Reduced net debtⁱ to $631.8 million in the second quarter of 2024, reflecting a reduction of $405.9 million over the first half of 2024.
• The increase in cash and reduction in long-term debt significantly reduced net debt to adjusted EBITDAⁱ to 0.8x at June 30, 2024 compared to 1.6x at the end of 2023. Achieved the targeted 1.2x net debt to adjusted EBITDAⁱ ratio outlined in the three prerequisites plan (the "3-P plan") for advancing Copper World well ahead of schedule.
• Deleveraging efforts continued into the third quarter of 2024 with an additional $48.5 million of open market purchases of the company's senior unsecured notes in July and August.

• Scheduled to complete the final payment under the gold prepay liability in August 2024, which was the financing instrument used to fund the refurbishment of the New Britannia gold mill. The elimination of the gold prepay will further increase the company's exposure to higher gold production in Snow Lake.
• Total liquidity substantially increased by 65% to $948.5 million at June 30, 2024 from $573.7 million at the end of 2023.

Continued Execution of Growth Initiatives to Further Enhance Copper and Gold Exposure

• Successfully ratified multi-year agreements with the unions representing members of Hudbay's workforce in Peru and Manitoba, with no disruption to operations, demonstrating the company's focus on working closely with its employees and community stakeholders to ensure aligned economic and social benefits.

• Stripping program for the next mining phase at Pampacancha is underway and is expected to lead to significantly higher copper and gold grades in the fourth quarter of 2024, which together with maintaining strong operating performance at Constancia is expected to continue to generate meaningful free cash flow in Peru.

• The New Britannia mill continued to exceed expectations, driving higher gold production in Manitoba. The mill achieved record throughput levels of nearly 2,100 tonnes per day in June and averaged 1,850 tonnes per day in the second quarter, exceeding its original design capacity of 1,500 tonnes per day and its 2024 budgeted capacity of 1,800 tonnes per day due to the successful implementation of process improvement initiatives and effective preventative maintenance measures.

• Post-acquisition plans to stabilize the Copper Mountain operations remain in progress with a focus on mining fleet ramp-up activities, accelerated stripping and increasing mill reliability. Higher mill availability of 94% and better-than-planned copper recoveries of 82% were achieved in the second quarter of 2024.

Summary of Second Quarter Results

Consolidated copper production of 28,578 tonnes in the second quarter of 2024 declined from the first quarter of 2024 but was in line with mine plan expectations. Consolidated gold production of 58,614 ounces in the second quarter declined from the strong levels achieved in the first quarter but was in line with mine plan expectations. Production was impacted by lower planned grades in Peru and Manitoba, a planned semi-annual mill maintenance shutdown in Peru and the execution of planned stripping programs at Pampacancha and Copper Mountain to access higher grades.

In the second quarter of 2024, consolidated cash cost per pound of copper produced, net of by-product creditsⁱ, was $1.14, compared to $0.16 in the first quarter of 2024. This change was mainly the result of lower gold by-product credits from lower gold sales volumes as well as lower copper production. Consolidated sustaining cash cost per pound of copper produced, net of by-product creditsⁱ, was $2.65 in the second quarter of 2024 compared to $1.32 in the prior quarter, due to the same reasons outlined above as well as higher sustaining capital expenditures in line with company guidance expectations.

During the second quarter of 2024, cash generated from operating activities of $138.5 million was relatively unchanged from the first quarter of 2024. Operating cash flow before change in non-cash working capital of $122.0 million in the second quarter of 2024 was lower than the first quarter. Operating cash flow before change in non-cash working capital was impacted by lower planned production levels, partially offset by higher realized metal prices and continued strong operational cost performance across the business. It was also impacted by lower copper sales volumes in Peru and lower zinc sales volumes in Manitoba due to timing of shipments. These cash flows benefited from effective working capital management as the company reduced stockpile while collecting on its receivables. Adjusted EBITDAⁱ was $145.0 million in the second quarter compared to $214.2 million in the first quarter of 2024 and was impacted by the same factors affecting operating cash flow as noted above.

Net loss attributable to owners and loss per share attributable to owners in the second quarter of 2024 were $16.6 million and $0.05, respectively, compared to net earnings attributable to owners and earnings per share attributable to owners of $59.4 million and $0.17, respectively, in the first quarter 2024. Net loss attributable to owners of $16.6 million was meaningfully impacted by tax expense of $20.8 million despite having earnings before tax of only $0.4 million in the quarter. The elevated tax expense was due to mining taxes that are calculated based on taxable mining profits in each operating jurisdiction, the limited deductibility of certain expenses and foreign exchange fluctuations on deferred tax balances. Adjusted net earnings attributable to ownersⁱ and adjusted net earnings per share attributable to ownersⁱ in the second quarter of 2024 were $0.1 million and nil per share, respectively, after adjusting for a $10.7 million revaluation loss related to the gold prepayment liability and revaluation of the company's strategic gold and copper hedges and investments, an $8.8 million revaluation of share-based compensation due to a higher share price and a $2.1 million write-down of PP&E, among other items.

As at June 30, 2024, total liquidity was $948.5 million, including $483.8 million in cash and cash equivalents, $40.0 million in short-term investments as well as undrawn availability of $424.7 million under the company's revolving credit facilities. Net debtⁱ declined substantially by $362.4 million during the second quarter of 2024 to $631.8 million as part of the company's efforts to deleverage the balance sheet. This was driven by the free cash flow generation from the operations and the equity offering which contributed cash of $386.2 million, net of transaction and issuance costs. Some of these funds were utilized to repay all $90.0 million of debt outstanding on the senior secured credit facilities as at March 31, 2024 and to repurchase and retire approximately $34.1 million of the company's senior unsecured notes. As a result, Hudbay has made significant progress towards achieving the deleveraging targets outlined in the 3-P plan for sanctioning Copper World.

Production Guidance Reaffirmed and Cash Cost Guidance Improved

Hudbay has reaffirmed its full year 2024 consolidated production guidance for all metals, including 137,000 to 176,000 tonnes of copper and 263,000 to 319,000 ounces of gold as the company anticipates stronger production in the second half of 2024 in accordance with the mine production profile. The company expects 2024 consolidated copper production to be below the midpoint of the guidance range, while 2024 consolidated gold production is expected to be above the midpoint of the guidance range. This is a result of a combination of lower-than-expected grades and timing impacts from heavy rains in Peru, as well as the ongoing ramp-up of stabilization efforts at Copper Mountain, offset by the continued strong operational performance in Manitoba driven by New Britannia performance and grades exceeding the company's expectations.

The company is improving its 2024 annual consolidated cash cost guidance range to $0.90 to $1.10 per pound from the original guidance range of $1.05 to $1.25 per pound, as a result of meaningful exposure to gold by-product credits and continued strong cost control. Hudbay has reaffirmed all other 2024 guidance metrics.

4 Strip ratio is calculated as waste mined divided by ore mined.

During the second quarter of 2024, the Peru operations produced 19,217 tonnes of copper, 10,672 ounces of gold, 450,833 ounces of silver and 369 tonnes of molybdenum. Production was lower than the first quarter of 2024 primarily due to planned lower grades as the company executes a stripping program at Pampacancha to advance to the next mining phase, as further discussed below, in addition to a planned semi-annual mill maintenance shutdown in the second quarter. The company is on track to achieve its 2024 production guidance for all metals in Peru.

---

Total ore mined in the second quarter of 2024 increased by 38% compared to the first quarter and was in line with the mine plan. Ore mined from Pampacancha during the second quarter decreased to 1.3 million tonnes compared with 2.2 million tonnes in the first quarter of 2024 as a result of higher capitalized stripping activities. Mining efforts at Pampacancha are focused on continuing the stripping program to advance to the next mining phase and the company is on track to resume mining in higher copper and gold grade areas later in the year.

The Peru operations continue to benefit from strong mill throughput, averaging approximately 87,000 tonnes processed per day year-to-date. Ore milled during the second quarter of 2024 was 4% lower than the first quarter due to the scheduled semi-annual mill maintenance shutdown. Ore milled included supplemental ore feed from stockpiles during the quarter as the team advances pit stripping activities. Milled copper and gold grades of 0.30% and 0.07 grams per tonne, respectively, decreased in the second quarter of 2024 compared to the first quarter due to lower amounts of high-grade copper and gold from Pampacancha, in addition to lower grades from the processing of stockpiled ore. Recoveries of copper and gold during the second quarter of 2024 were 83% and 61%, respectively, and were in line with metallurgical models.

Combined mine, mill and G&A unit operating costsⁱ in the second quarter were $12.68 per tonne, 16% higher than the first quarter of 2024 primarily due to higher milling costs and lower throughput associated with the planned semi-annual mill maintenance shutdown.

Payable copper metal sold in the second quarter of 2024 was lower than the first quarter due to lower copper production and a 10,000 wet metric tonne copper concentrate shipment that remained unsold at the end of the second quarter and was recognized as revenue early in the third quarter of 2024.

Cash cost per pound of copper produced, net of by-product creditsⁱ, in the second quarter of 2024 was $1.78, an increase from the $0.43 achieved in the first quarter of 2024 due to lower planned copper production, higher milling costs and lower by-product credits, partly offset by lower treatment and refining charges. Full year cash costs are expected to be within the 2024 guidance range.

Sustaining cash cost per pound of copper produced, net of by-product creditsⁱ, was $2.61 for the second quarter, higher than the first quarter of 2024 of $1.06, primarily due to the same factors affecting cash cost.

During the quarter, the Peruvian Ministry of Energy and Mines approved a regulatory change, Supreme Decree 011-2024-EM, to allow mining companies in Peru to increase throughput by up to 10% above permitted levels. Previously, the regulation only allowed for an increase of up to 5%. As such, the company is evaluating the potential to increase future production at Constancia.

The Manitoba operations produced 43,488 ounces of gold, 2,642 tonnes of copper, 8,087 tonnes of zinc and 210,647 ounces of silver during the second quarter of 2024. Compared to the exceptional results achieved in the first quarter of 2024, production decreased primarily due to a planned lower grade mining sequence in the quarter. The Snow Lake operations in Manitoba maintained steady production results despite overcoming challenges in the second quarter of 2024, including forest fires and temporary production interruptions at the Lalor mine, partially offset by stronger than budgeted throughput at New Britannia. The Manitoba team's resilience and dedication ensured that the operations continued to function effectively and efficiently while achieving quarterly production targets. The company is on track to achieve its 2024 production guidance for all metals in Manitoba.

Total ore mined in Manitoba in the second quarter of 2024 was 5% lower than the first quarter. Gold, copper, zinc and silver grades mined at Lalor during the second quarter were 23%, 18%, 5% and 5% lower, respectively, compared with the first quarter of 2024. These changes reflect temporary Lalor mine production disruptions and the completion of a planned lower grade mining sequence in the quarter. During the quarter, the Lalor mine encountered issues with the production hoist gearbox and electrical faults on the hoist drives, causing a ten-day stoppage in hoisting ore. The maintenance teams collaborated closely with original equipment manufacturers to resolve these issues quickly. During the hoisting outage, the operations team focused on value-added activities, including underground ore buildup close to the shaft, waste filling, increased maintenance, building longhole inventory, and trucking ore to surface. Additionally, the team implemented stope design modifications that yielded positive results by improving mucking efficiency throughout the lifecycle of the stopes.

The New Britannia mill consistently operated above nameplate capacity, averaging approximately 1,850 tonnes per day in the second quarter of 2024 and achieving a new monthly record of nearly 2,100 tonnes per day in June. Ongoing efforts to increase throughput are aligned with the company's long-term objectives to maximize gold production by directing more gold ore from Lalor to the New Britannia mill for higher gold recoveries. Recoveries of gold, copper and silver in the second quarter of 2024 were 90%, 94% and 83%, respectively.

The Stall mill processed 5% more ore in the second quarter of 2024 than the first quarter. Recoveries of gold, copper and silver in the second quarter of 2024 were slightly lower than the first quarter primarily due to lower grades.

Combined mine, mill and G&A unit operating costsⁱ in the second quarter of 2024 were C$225 per tonne, a 5% decrease compared to the first quarter. This decrease was a result of higher throughput and lower mining, milling and G&A costs compared to the first quarter.

Payable zinc metal sold was lower than prior periods as there was a 10,000 wet metric tonne zinc concentrate shipment that remained unsold at the end of the second quarter and will be recognized as revenue in the third quarter of 2024.

Cash cost per ounce of gold produced, net of by-product creditsⁱ, in the second quarter of 2024 was $771 per ounce, a 5% increase compared to the first quarter primarily due to lower gold production. Full year gold cash cost is expected to remain within the 2024 guidance range.

Sustaining cash cost per ounce of gold produced, net of by-product creditsⁱ, in the second quarter of 2024 was $1,163, an increase of 22% compared to the first quarter due to lower gold production and higher sustaining capital costs during the quarter.

Hudbay's Manitoba operation also progressed its sustainability initiatives by reducing propane and diesel consumption in the first half of 2024 compared to the same period in 2023. In addition, at Lalor, an initiative to capture and recycle natural groundwater and use it as process water to reduce the freshwater intake into the mine has proven to be effective.

⁵ Copper Mountain mine results are stated at 100%. Hudbay owns 75% of Copper Mountain mine.

During the second quarter of 2024, the British Columbia operations produced 6,719 tonnes of copper, 4,454 ounces of gold and 77,227 ounces of silver. Production of copper was slightly lower than the first quarter of 2024 primarily as a result of lower head grades from the use of stockpiled ore to feed the mill while mining activities are focused on executing the planned stripping program. Gold production was consistent with the first quarter of 2024. The company has reaffirmed its 2024 production guidance ranges for all metals in British Columbia.

Hudbay has been focused on advancing operational stabilization plans, including opening up the mine by adding additional mining faces, adding to the mining fleet, optimizing the ore feed to the plant and implementing plant improvement initiatives that mirror Hudbay's successful processes at Constancia. While the benefits of these stabilization plans are not expected to be fully realized until 2025, the mine has successfully increased the total tonnes moved and has seen stronger mill performance as demonstrated by higher mill availability of 94% and above-target copper recoveries of 82% in the second quarter of 2024. As a result, year-to-date mill performance has resulted in the highest mill availability and highest copper recoveries in the last decade.

Total ore mined at Copper Mountain in the second quarter of 2024 was 2.2 million tonnes, a decrease compared to the first quarter of 2024. As planned, ore stockpiles were utilized as ore feed to the mill while the mine operation team increased waste stripping activities. Total material moved continued to ramp up in the quarter as a result of effective usage of the mining fleet as part of the fleet production ramp up plan to execute the accelerated stripping program to access higher head grades. This plan entails remobilization of the existing mining truck fleet and the deployment of an additional shovel, drill and associated equipment. Earlier this year, the company ordered five new haul trucks to execute additional stripping activities over the next three years at a lower cost than the contractor mining approach that was contemplated in the technical report. Three of the five new haul trucks and the additional shovel and drill were put in production in June, and all five haul trucks were in operation by August. As a result, total material moved is expected to continue to increase quarter-over-quarter as per the mine plan. 

---

The mill processed 3.2 million tonnes of ore during the second quarter of 2024, a 2% increase over the first quarter, benefiting from stabilization and reliability initiatives within the mill processing circuit. The average mill availability during the second quarter of 2024 increased to 94% from 90% in the first quarter, while maintaining a stable throughput rate. Mill throughput in the second quarter of 2024 was limited by reduced reliability of the secondary crushing circuit, caused primarily by unplanned maintenance events and elevated clay material in the mine feed. During the quarter, a number of initiatives were advanced to address these issues and other identified constraints and improve throughput to targeted levels, with the benefits expected to be realized in the second half of 2024. Initiatives that began earlier in the year are progressing on target, including reprogramming the mill expert system, installation of advanced semi-autogenous grinding control instrumentation, redesign of the SAG liner package and updated operational procedures intended to remove magnetite from the pebble stream.

Milled copper grades during the second quarter of 2024 were 7% lower than the first quarter as the company continued to draw on stockpiled ore. Copper recoveries were slightly lower than the first quarter of 2024, but in line with expectations despite lower grades as the operations improved the regrind circuit constraint and implemented the flotation operational strategy improvements, including reagent selection and dose modification.

The benefits of the operational stabilization improvements are expected to continue to be realized throughout 2024. The company is also accelerating engineering studies to debottleneck and increase the nominal plant capacity to 50,000 tonnes per day earlier than was contemplated in the technical report.

Combined mine, mill and G&A unit operating costsⁱ in the second quarter of 2024 were C$19.65 per tonne milled, 17% lower than the first quarter of 2024 primarily due to lower mining costs as there were high ore rehandling costs in the first quarter of 2024. Combined unit operating costs are expected to decrease over time as the company continues to implement its stabilization and optimization initiatives at Copper Mountain. As the hiring and training of additional haul truck drivers continues, the company expects to have a fully trained complement of truck drivers in August to support the larger mining fleet, which is expected to increase material moved and reduce unit operating costs.

Cash cost per pound of copper produced, net of by-product creditsⁱ, in the second quarter of 2024 was $2.67. Cash costs were lower than the first quarter of 2024 by 23% for the same reason as mentioned above regarding the unit cost variance. Full year cash costs are expected to be within the 2024 guidance range.

Sustaining cash cost per pound of copper produced, net of by-product creditsⁱ, in the second quarter of 2024 was $5.56, 15% higher than the first quarter mainly as a result of planned higher capitalized stripping costs to unlock the mine potential according to the company's stabilization plan.

Enhanced Balance Sheet through Successful Equity Offering and Accelerated Debt Reduction

The company took several prudent measures in the second quarter of 2024 to further improve its balance sheet position, including more than $150 million of combined debt repayments and gold prepayment liability reductions:

• Completed successful $402.5 million equity offering - On May 24, 2024, Hudbay closed a public offering of common shares for gross proceeds of $402.5 million, resulting in net proceeds of $386.2 million after transaction costs.

• Fully repaid $90.0 million outstanding under the revolving credit facilities - The company fully repaid $90 million of debt outstanding under its revolving credit facilities during the quarter with no remaining amounts drawn (other than letters of credit).

• Repurchased and retired $34.1 million of senior unsecured notes - The company made open market purchases of $11.6 million of the 2026 senior unsecured notes and $22.5 million of the 2029 senior unsecured notes during the quarter.

• Delivered $24.0 million under gold forward sale and prepay agreement - The company completed three additional months of gold deliveries during the quarter and is scheduled to fully repay the gold prepay facility by the end of August 2024, which was used to fund the refurbishment of the New Britannia gold mill.

As a result of these deleveraging efforts and continued cash flow generation, Hudbay has substantially reduced net debtⁱ to $631.8 million at June 30, 2024, from $1,037.7 million at the end of 2023. The net debt reduction, together with higher levels of adjusted EBITDAⁱ over the last twelve months, has significantly improved the company's net debt to adjusted EBITDA ratioⁱ to 0.8x compared to 1.6x at the end of 2023. 

Subsequent to the quarter, deleveraging efforts continued in July and August with an additional $48.5 million of open market purchases of the senior unsecured notes, at a discount.

The improved balance sheet flexibility and accelerated debt reduction significantly advances the company's progress as part of its 3-P plan for sanctioning Copper World, and results in the successful achievement of the targeted 1.2x net debt to adjusted EBITDA ratio well ahead of schedule.

Disciplined Capital Allocation Driving Increased Copper and Gold Exposure

Hudbay continued to deliver positive free cash flow generation this quarter with strong gold production in Manitoba and strong cost control across the operations, while advancing planned stripping activities in Peru and British Columbia to drive higher copper and gold production levels in the second half of 2024. The company also continues to evaluate areas to further improve mill performance across the business as part of its continuous improvement efforts.

In addition to enhancing balance sheet flexibility through debt repayments as mentioned above, the net proceeds of the equity offering are intended to fund near-term growth initiatives, including acceleration of mine pre-stripping activities and mill optimization initiatives at Copper Mountain, and to evaluate mill throughput enhancement opportunities at Constancia and New Britannia.

Copper Mountain Stabilization Efforts to Drive Higher Copper Production

The key elements of Hudbay's stabilization plans for Copper Mountain include executing a campaign of accelerated stripping to access higher grades and implementing several plant improvement initiatives to increase mill throughput and recoveries.

Earlier this year, the company commenced a three-year accelerated stripping program to mitigate the substantially reduced stripping that occurred over the four years prior to Hudbay's acquisition. The company has successfully remobilized all 28 haul trucks and added five additional haul trucks this year to execute the accelerated stripping campaign at a lower cost and avoid contractor mining costs. The accelerated stripping program is expected to improve operating efficiencies and lower unit operating costs.

---

Hudbay's mine plan as disclosed in the December 2023 technical report for Copper Mountain assumes a mill ramp up to its nominal capacity of 45,000 tonnes per day in 2025 and an expansion to the permitted capacity of 50,000 tonnes per day in 2027. Mill initiatives are progressing as planned for 2024, including reprogramming the mill expert system, installing advanced grinding control instrumentation, flotation operational strategy improvements and improved maintenance practices. In the second half of 2024, the company is also accelerating various engineering studies to increase mill throughput to 50,000 tonnes per day earlier than was originally contemplated in the technical report.

Hudbay has exceeded the targeted $10 million in annualized corporate synergies and is on track to realize the three-year annual operating efficiencies target.

New Britannia Mill Performance Exceeding Expectations to Drive Higher Gold Production

Hudbay completed the brownfield investment in New Britannia in 2021 and refurbished the mill to a nominal capacity of 1,500 tonnes per day. This provided additional processing capacity to the Snow Lake operations and allowed the company to achieve higher gold recoveries of approximately 90% as Lalor transitioned to the higher gold and copper areas of the mine plan. The New Britannia mill has been consistently exceeding performance expectations, achieving 1,650 tonnes per day in 2023, more than 1,850 tonnes per day in the first half of 2024, and a new monthly record of nearly 2,100 tonnes per day in June 2024.

The final payment for the New Britannia gold prepay financing in August 2024 further enhances the company's exposure to higher gold production in Snow Lake. With approximately two million ounces of contained gold in current mineral reserve estimates and another 1.4 million ounces of contained gold in inferred mineral resources, the New Britannia investment has unlocked significant value in Snow Lake. This could be further enhanced by regional exploration upside and the current strong gold price environment.

In the first quarter of 2024, the company received a permit approval to increase the production rate at New Britannia to 2,500 tonnes per day, which will provide the opportunity to process more Lalor ore at the New Britannia mill and create additional processing capacity for potential new regional discoveries in Snow Lake.

Peru Investment Programs to Drive Higher Copper and Gold Production

The company is well-advanced in executing a stripping program for the next mining phase at the Pampacancha pit. This stripping program is expected to continue until September and is intended to unlock higher copper and gold grades at the Peru operations in the fourth quarter of 2024.

During the second quarter of 2024, the Peruvian government approved regulatory changes to allow mining companies to increase their annual mill throughput levels up to 10% above permitted levels. Hudbay is evaluating the potential to increase planned production levels at Constancia, as early as 2026, which could partially offset the grade declines after the completion of mining at Pampacancha in late 2025.

Advancing Permitting at Copper World

The first key state permit required for Copper World, the Mined Land Reclamation Plan, was initially approved by the Arizona State Mine Inspector in October 2021 and was subsequently amended and approved to reflect a larger private land project footprint. This approval was challenged in state court, but the challenge was dismissed in May 2023. In late 2022, Hudbay submitted the applications for an Aquifer Protection Permit and an Air Quality Permit to the Arizona Department of Environmental Quality. The public comment period for the Aquifer Protection Permit was completed in the second quarter while the public comment period for the Air Quality Permit commenced in July. Hudbay continues to expect to receive these two outstanding state permits in the second half of 2024.

Copper World is one of the highest-grade open pit copper projects in the Americasⁱⁱⁱ with proven and probable mineral reserves of 385 million tonnes at 0.54% copper. Copper World Phase I contemplates average annual copper production of 85,000 tonnes over a 20-year mine life, at average cash costs and sustaining cash costs of $1.47 and $1.81 per pound of copper, respectively. In addition, there remains approximately 60% of the total copper contained in measured and indicated mineral resources (exclusive of mineral reserves), providing significant potential for a Phase II expansion and mine life extension. The inferred mineral resource estimates are at a comparable copper grade and also provide significant upside potential. Copper World is expected to provide meaningful copper to support the U.S. domestic supply chain.

Exploration Update

Manitoba Exploration

Lalor Northwest Follow-up Drilling Confirms Two Mineralized Zones

Hudbay's 2024 winter drill program included follow-up drilling of a geophysical anomaly located northwest of Lalor, which was initially drilled in 2023. Recent positive assay results at Lalor Northwest confirm the discovery of two mineralized zones located within 400 metres of the existing Lalor underground infrastructure, as shown in Figure 1.

In 2023, hole CH2302 intersected two mineralized zones, including 4.8 metres at 2.97% copper, 2.92 grams per tonne gold and 80.3 grams per tonne of silver. Earlier in 2024, hole CH2406 intersected the same two mineralized zones, including 9.0 metres of 2.88% copper, 6.27 grams per tonne of gold and 88.9 grams per tonne of silver. See "Qualified Person and NI 43-101".

These promising results justified additional follow-up drilling in the summer of 2024 with two drill rigs currently turning at Lalor Northwest. Drilling results are expected to be received by the end of the year and will be used to determine the potential size of Lalor Northwest and the potential for future underground drift development from Lalor for further definition drilling. Lalor Northwest has the potential to add near-term production growth at Lalor, extend mine life and create additional value from the Snow Lake operations.

Snow Lake 2024 Regional Geophysics Program Identifies Prospective Targets; Summer Drill Program Initiated

During the first half of 2024, Hudbay conducted the company's largest geophysics program in its history in Snow Lake. This program resulted in the identification of a number of anomalies and prospective targets across the Snow Lake tenements which are currently being tested near the former Reed and Anderson mines and in the vicinity of the Bur and Rail deposits that were acquired as part of the Rockcliff transaction. Hudbay intends to continue similar size geophysical programs and mapping of the company's consolidated land package in the region in 2025.

---

The 2024 geophysical program included surface electromagnetic (EM) surveys covering a 25 square kilometre area, as highlighted in Figure 2, including the recently acquired Cook Lake claims that had been previously untested by modern deep geophysics, which was the discovery method for the Lalor deposit. This surface EM survey used cutting-edge techniques that enabled the team to detect deep targets at depths of over 1,000 metres below surface. The new EM methodology is unique to Hudbay and will lead to advanced understanding of the mineralization at depths previously undetectable.

In addition, one very strong deep anomaly located at Cook Lake North, approximately six kilometres from Lalor, was identified through borehole EM surveys. 2024 drilling intersected multiple horizons of non-economic mineralization but a deeper and stronger conductor will be tested in the coming weeks by extending the drill hole at depth as part of the summer-fall 2024 exploration program.

Hudbay continues to execute its 2024 drilling program with the goal of extending known mineralization near the Lalor deposit to further extend mine life as well as to find a new anchor deposit within trucking distance of the Snow Lake processing infrastructure. The 2024 summer drill program is well underway, and the team currently has six drill rigs turning in Snow Lake, including two drills at Lalor Northwest as mentioned above. The company expects to ramp up to eight drill rigs by the end of August to test new geophysical targets and complete follow-up drilling at potential regional satellite deposits. Results from the summer drill program are expected in late 2024.

Advancing Access to the 1901 Deposit

In the first quarter of 2024, Hudbay commenced the development of a smaller profile drift from the existing Lalor ramp towards the 1901 deposit. The 1901 development drift is expected to reach the mineralization in early 2025, following which the company plans to conduct definition drilling intended to confirm the optimal mining method, evaluate the orebody geometry and continuity, and convert inferred mineral resources in the gold lenses to mineral reserves. Pending positive results from the drilling programs, the plan is to initiate a haulage drift and other related mining infrastructure in 2025 and 2026 in anticipation of full production from the 1901 deposit in 2027.

Continuing to Advance Studies for Flin Flon Tailings Reprocessing

Hudbay continues to advance studies to evaluate the opportunity to reprocess Flin Flon tailings where more than 100 million tonnes of tailings have been deposited for over 90 years from the mill and the zinc plant. The studies are evaluating the potential to re-purpose the existing Flin Flon concentrator, which is currently on care and maintenance, with flow sheet modifications to reprocess tailings to recover critical minerals and precious metals while creating environmental and social benefits for the region.

The company continues to advance metallurgical test work, and during the second quarter of 2024, it received results from the initial confirmatory drill program in the section of the tailings facility that was utilized by the zinc plant. The results confirmed the grades of precious metals and critical minerals previously estimated from historical zinc plant records. An early economic study to evaluate the opportunity to reprocess initially the portion where the zinc plant tailings were deposited has shown promising results that warrant further engineering work in the second half of 2024. A similar study is planned with respect to the mill tailings.

Peru Exploration

Hudbay controls a large, contiguous block of mineral rights with the potential to host mineral deposits in close proximity to the Constancia processing facility, including the past producing Caballito property and the highly prospective Maria Reyna property. The company commenced early exploration activities at Maria Reyna and Caballito after completing a surface rights exploration agreement with the community of Uchucarcco in August 2022. As part of the drill permitting process, environmental impact assessment applications were submitted for the Maria Reyna property in November 2023 and for the Caballito property in April 2024. The environmental impact assessment (EIA) for Maria Reyna was approved by the government in June 2024 and the Caballito application continues to make progress through the permitting process. This represents one of several steps in the drill permitting process, which is expected to take approximately 12 months to complete after the EIAs are approved.

---

New Concentrate Contracts with Attractive Terms

In light of the extremely tight copper concentrate market that currently exists, Hudbay has strategically taken steps to preserve uncommitted copper concentrate units. This has allowed the company to enter into several new contracts covering approximately 20% to 25% of its estimated Constancia concentrate sales over the next four years with favourable treatment and refining charges ("TC/RC"), including contracts with fixed TC/RCs that are negative in certain years and other contracts that have TC/RC priced at significant discounts of 45% to 65% to market benchmark terms.

Collective Bargaining Agreements Ratified in Manitoba and Peru

In June, new three-and-a-half year collective bargaining agreements were ratified by the members of all five unions at Hudbay's Manitoba operations, effective July 1, 2024. In July, a new three-year agreement was signed with the union at Hudbay's Peru operations, effective November 10, 2023. The ratification of these agreements is a significant achievement and demonstrates Hudbay's focus on working closely with its employees and community stakeholders to ensure aligned economic and social benefits.

Dividend Declared

A semi-annual dividend of C$0.01 per share was declared on August 12, 2024. The dividend will be paid out on September 20, 2024 to shareholders of record as of close of business on September 3, 2024.

Non-IFRS Financial Performance Measures

Adjusted net earnings (loss) attributable to owners, adjusted net earnings (loss) per share attributable to owners, adjusted EBITDA, net debt, cash cost, sustaining and all-in sustaining cash cost per pound of copper produced, cash cost and sustaining cash cost per ounce of gold produced, combined unit costs and ratios based on these measures are non-IFRS performance measures. These measures do not have a meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other issuers. These measures should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS and are not necessarily indicative of operating gross profit or cash flow from operations as determined under IFRS. Other companies may calculate these measures differently.

Management believes adjusted net earnings (loss) attributable to owners and adjusted net earnings (loss) per share attributable to owners provides an alternate measure of the company's performance for the current period and gives insight into its expected performance in future periods. These measures are used internally by the company to evaluate the performance of its underlying operations and to assist with its planning and forecasting of future operating results. As such, the company believes these measures are useful to investors in assessing the company's underlying performance. Hudbay provides adjusted EBITDA to help users analyze the company's results and to provide additional information about its ongoing cash generating potential in order to assess its capacity to service and repay debt, carry out investments and cover working capital needs. Net debt is shown because it is a performance measure used by the company to assess its financial position. Net debt to adjusted EBITDA is shown because it is a performance measure used by the company to assess its financial leverage and debt capacity. Cash cost, sustaining and all-in sustaining cash cost per pound of copper produced are shown because the company believes they help investors and management assess the performance of its operations, including the margin generated by the operations and the company. Cash cost and sustaining cash cost per ounce of gold produced are shown because the company believes they help investors and management assess the performance of its Manitoba operations. Combined unit cost is shown because Hudbay believes it helps investors and management assess the company's cost structure and margins that are not impacted by variability in by-product commodity prices.

The following tables provide detailed reconciliations to the most comparable IFRS measures.

Figure 1: Lalor Northwest Follow-up Drilling Confirms Two Mineralized Zones

Recent positive assay results at Lalor Northwest confirm the discovery of two mineralized zones located within 400 metres of the existing Lalor underground infrastructure and have the potential to add near-term production growth at Lalor and extend mine life at Hudbay's Snow Lake operations.

Figure 2: Snow Lake 2024 Regional Geophysics Program Identifies Prospective Targets

The 2024 geophysical program included surface electromagnetic (EM) surveys covering a 25 square kilometre area, including the recently acquired Cook Lake claims that had been previously untested by modern deep geophysics. This new surface EM methodology is unique to Hudbay and detects deep targets at depths of over 1,000 metres below surface. In addition, one very strong deep borehole EM conductor at Cook Lake North will be drill tested in the coming weeks by extending the drill hole to a depth of approximate 2,400 metres.
