EXPLANATORY NOTE

References throughout this Amendment No. 1 to the Quarterly Report on Form 10-Q to “we,” “us,” “Gatos Silver,” “Company” or “our Company” are to Gatos Silver Inc., unless the context otherwise indicates.

This Amendment No. 1 (“Amendment No. 1”) amends the Quarterly Report on Form 10-Q of Gatos Silver, Inc. for the three and nine months ended September 30, 2023 (“Affected Period”), as filed with the Securities and Exchange Commission (“SEC”) on November 6, 2023 (the “Original Filing”).

This Amendment No. 1 contains the restated financial statements for the Company for the Affected Period to correct the classification of the capital distribution received from the Los Gatos Joint Venture ("LGJV") on the Condensed Consolidated Statement of Cash Flows. Based on management's judgement, the Company considered the declaration of the capital distribution (in its legal form) to be the nature of the activity that generated the cash flow and, therefore, classified the capital distribution as cash provided by investing activities on the Condensed Consolidated Statements of Cash Flows. On further analysis, it was determined that management should have considered the underlying source of the cash flow at the LGJV that generated the funds for the capital distribution when determining its classification on the Company's Condensed Consolidated Statements of Cash Flows. The capital distribution received previously classified as cash flow provided by investing activities should have been classified as cash flows provided by operating activities. The Condensed Consolidated Balance sheets and balance of cash and cash equivalents as of September 30, 2023, and the Condensed Consolidated Statements of Income and Comprehensive Income and the Condensed Consolidated Statements of Shareholders’ Equity for the three and nine months ended September 30, 2023, are not impacted by this change. See Note 3. Restatement of Previously Issued Financial Statements to the condensed consolidated financial statements included herein for additional information.

This Amendment No. 1 contains the following sections:

•Item 1. Financial Statements

•Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

•Item 4. Controls and Procedures

•Exhibits 31, 32, 101 and 104 of Item 6. Exhibits.

Except as described above, and as further described in Note 3 to the condensed consolidated financial statements in this Form 10-Q/A, this Amendment No. 1 does not amend, update or change any other items or disclosures contained in the Original Filing, and accordingly, this Amendment No. 1 does not reflect or purport to reflect any information or events occurring after the original filing date or modify or update those disclosures affected by subsequent events. Accordingly, this Amendment No. 1 should be read in conjunction with the Original Filing and the Company’s other filings with the SEC. Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Original Filing.

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

(In thousands of United States dollars, except share amounts)

1. Basis of Presentation

Basis of Consolidation and Presentation

The financial statements represent the condensed consolidated financial position and results of operations of Gatos Silver, Inc. and its subsidiaries, Gatos Silver Canada Corporation and Minera Luz del Sol S. de R.L. de C.V. Unless the context otherwise requires, references to Gatos Silver or the Company mean Gatos Silver, Inc. and its consolidated subsidiaries.

The interim condensed consolidated financial statements are unaudited, but include all adjustments, consisting of normal recurring entries, which are necessary for a fair presentation for the dates and periods presented. Interim results are not necessarily indicative of results for a full year. The financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information. Accordingly, they do not include all financial information and disclosures required by GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 10-K”).

2. Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

The consolidated financial statements for the year ended December 31, 2022, disclose those accounting policies considered significant in determining results of operations and financial position. There have been no material changes to, or in the application of, the accounting policies previously identified and described in the 2022 10-K.

Recent Accounting Pronouncements

In October 2023, the FASB issued ASU No. 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative. The amendments in this update modify the disclosure or presentation requirements of a variety of Topics in the Codification. Certain amendments represent clarifications to or technical corrections of the current requirements. Each amendment in the ASU will only become effective if the SEC removes the related disclosure or presentation requirement from its existing regulations by June 30, 2027. The Company is still assessing the impact of the standard.

There have been no other accounting pronouncements issued or adopted during the nine months ended September 30, 2023, which are expected to have a material impact on the financial statements.

3. Restatement of Previously Issued Financial Statements

In accordance with ASC 250, Accounting Changes and Error Corrections (“ASC 250”), the following item is treated as an error to the interim condensed consolidated financial statements for the three and nine months ended September 30, 2023, and, therefore, requires that the condensed consolidated financial statements be restated.

Statement of Cash flows

During the preparation of the financial statements for the three months ended March 31, 2024, the Company identified that the capital distribution received from its investment in affiliates classified as cash provided by investing activities on the Condensed Consolidated Statements of Cash Flows should have been classified as cash provided by operating activities. Based on management's judgement, the Company considered the declaration of the capital distribution (in its legal form) to be the nature of the activity that generated the cash flow and, therefore, classified the capital distribution as cash provided by investing activities on the Condensed Consolidated Statements of Cash Flows. On further analysis, it was determined that management should have considered the underlying source of the cash flow at the LGJV that generated the funds for the capital distribution when determining its classification on the Company's Condensed Consolidated Statements of Cash Flows. The capital distribution received previously classified as cash flow provided by investing activities should have been classified as cash flows provided by operating activities

The impact of the restatement on the Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2023, is presented below. The Condensed Consolidated Balance Sheet and balance of cash and cash equivalents as of September 30,

Stock Option Transactions

The Company's stock options have a contractual term of 10 years and entitle the holder to purchase shares of the Company's common stock. The stock options granted to the Company's employees have a service period of three years. The stock options granted to non-employee directors vest immediately.

The Company granted 1,132,520 stock options during the three and nine months ended September 30, 2023, with a weighted-average grant-date fair value per share of $2.93, and granted nil and 100,000 stock options during the three and nine months ended September 30, 2022, with a weighted-average grant-date fair value per share of $5.83. The stock options granted in September 2023 represented a portion of 2022 compensation due to the Company being in an extended blackout period in 2022 and a portion of 2023.

Of the stock options granted, 470,574 vested immediately, including stock options granted to non-employee directors. No stock options were exercised in the three and nine months ended September 30, 2023 and 2022.

Total unrecognized stock-based compensation expense as of September 30, 2023, was $2,843, which is expected to be recognized over a weighted average period of 2.1 years.

Stock option activity for the nine months ended September 30, 2023, is summarized in the following tables:


Employee & Director Options	Number of options	Weighted‑ Average Exercise Price Per Share
Outstanding at December 31, 2022	1,701,530	$	14.27
Granted on September 11, 2023	1,132,520	$	5.04
Forfeited	(194,760)	$	16.19
Outstanding at September 30, 2023	2,639,290	$	9.14
Vested at September 30, 2023	1,687,675	$	10.41

The following assumptions were used to compute the fair value of the options granted using the Black-Scholes option valuation model:

	January 2022		September 2023
Risk-free interest rate	1.74	%	4.39	%
Dividend yield	—		—
Estimated volatility	60.75	%	57.67	%

LGJV Personnel Options	Number of options	Weighted‑ Average Exercise Price Per Share
Outstanding at December 31, 2022	32,393	$	7.31
Outstanding and vested at September 30, 2023	32,393	$	7.31

Performance Share Unit ("PSU") Transactions

On December 17, 2021, 119,790 PSUs were granted to the Company’s employees with a weighted average grant date fair value per share of $14.22. At September 30, 2023, there were 40,802 PSUs outstanding. On September 30, 2023, unrecognized compensation expense related to the PSUs was $210, which is expected to be recognized over a weighted-average period of 1.2 years.

Restricted Stock Unit ("RSU") Transactions

RSUs granted are reported as equity awards with a fair value of each RSU equal to the fair value of the Company's common stock on the grant date and vest on the third anniversary of the grant date. Each earned RSU represents the right to receive one share of the Company's common stock.

On September 11, 2023, the Company granted 925,172 RSUs with grant date fair value of $5.04. The RSUs granted have varying vesting dates due to a portion being granted as part of 2022 compensation due to the Company being in an extended blackout period in 2022.

Compensation expense is recognized ratably from the grant date over the requisite vesting period. On September 30, 2023, unrecognized compensation expense related to the RSUs was $4,476, which is expected to be recognized over a weighted-average period of 1.4 years.

Table of Contents

Deferred Stock Unit ("DSU") Transactions

DSUs are awarded to directors at the discretion of the Board of Directors. The DSUs are fully vested on the grant date and each DSU entitles the holder to receive one share of the Company’s common stock upon the director’s cessation of continuous service. Non-employee directors are eligible to elect to defer receipt of any portion of annual retainers or meeting fees and take payment in the form of DSUs. The fair value of the DSUs is equal to the fair value of the Company’s common stock on the grant date.

The Company granted 108,490 DSUs during the three and nine months ended September 30, 2023, and nil during the three and nine months ended September 30, 2022. The 2023 grant included DSU compensation related to 2022 that could not be issued due to the Company being in an extended blackout period in 2022 and a portion of 2023.

The following table summarizes the DSU activity for the nine months ended September 30, 2023:


Employee and Director DSUs	Shares	Weighted‑ Average Grant Price
Outstanding at December 31, 2022	146,796	$	10.88
Granted	108,490	$	5.11
Outstanding at September 30, 2023	255,286	$	8.43

8. Net Income per Share

For the three and nine months ended September 30, 2023, and September 30, 2022, stock options outstanding have been excluded from the dilutive earnings per common share calculation as the exercise price of these stock options was greater than the average market value of common stock for those periods, resulting in an anti-dilutive effect. For the three and nine months ended September 30, 2023, and September 30, 2022, weighted average outstanding DSUs and RSUs are included in dilutive earnings per common share calculation. All outstanding PSUs were excluded from the diluted earnings per common share calculation as the PSUs do not currently meet the criteria for issuance.

A reconciliation of basic and diluted earnings per common share for the three and nine months ended September 30, 2023 and 2022, is as follows:


	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Net income	$	3,288	$	3,504	$	530	$	9,785

9. Fair Value Measurements

The Company establishes a framework for measuring the fair value of assets and liabilities in the form of a fair value hierarchy that prioritizes the inputs into valuation techniques used to measure fair value into three broad levels. This hierarchy gives the highest priority to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs. Further, financial assets and liabilities should be classified by level in their entirety based upon the lowest level of input that was significant to the fair value measurement. The three levels of the fair value hierarchy are as follows:

Table of Contents

Level 1: Unadjusted quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date.

Level 2: Quoted prices in inactive markets for identical assets or liabilities, quoted prices for similar assets or liabilities in active markets, or other observable inputs either directly related to the asset or liability or derived principally from corroborated observable market data.

Level 3: Unobservable inputs due to the fact there is little or no market activity. This entails using assumptions in models which estimate what market participants would use in pricing the asset or liability.

Assets and Liabilities that are Measured at Fair Value on a Non-recurring Basis

The Company discloses and recognizes its non-financial assets and liabilities at fair value on a non-recurring basis and makes adjustments to fair value, as needed (for example, when there is evidence of impairment).

The Company recorded its initial investment in affiliates at fair value within Level 3 of the fair value hierarchy, as the valuation was determined based on internally developed assumptions with few observable inputs and no market activity.

10. Commitments, Contingencies and Guarantees

In determining its accruals and disclosures with respect to loss contingencies, the Company will charge to income an estimated loss if information available prior to the issuance of the financial statements indicates that it is probable that a liability has been incurred at the date of the financial statements and the amount of the loss can be reasonably estimated. Legal expenses associated with the commitments and contingencies are expensed as incurred. If a loss contingency is not probable or reasonably estimable, disclosure of the loss contingency is made in the financial statements when it is at least reasonably possible that a material loss could be incurred.

Environmental Contingencies

The Company’s mining and exploration activities are subject to various laws, regulations and permits governing the protection of the environment. These laws, regulations and permits are continually changing and are generally becoming more restrictive. The Company has made, and expects to make in the future, expenditures to comply with such laws, regulations and permits, but cannot predict the full amount of such future expenditures.

Legal

On February 22, 2022, a purported Company stockholder filed a putative class action lawsuit in the United States District Court for the District of Colorado (the "District Court") against the Company, certain of our former officers, and several directors (the "U.S. Class Action"). An amended complaint was filed on August 15, 2022. The amended complaint, allegedly brought on behalf of certain purchasers of the Company’s common stock and certain traders of call and put options on the Company’s common stock from December 9, 2020 through January 25, 2022, seeks, among other things, damages, costs, and expenses, and asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 as well as Sections 11 and 15 of the Securities Act of 1933. The amended complaint alleges that certain individual defendants and the Company, pursuant to the control and authority of the individual defendants, made false and misleading statements and/or omitted certain material information regarding the mineral resources and reserves at the Cerro Los Gatos mine. The Company and all defendants filed a motion to dismiss this action on October 14, 2022. That motion was fully briefed as of December 23, 2022. On April 26, 2023, following a joint motion, the Court postponed its ruling on the defendants’ motion to dismiss until on or after June 16, 2023.

On June 13, 2023, the Company entered into an agreement in principle to settle the U.S. Class Action. Subject to certain conditions, including class certification by the District Court, the execution of a definitive stipulation of settlement and approval of the settlement by the District Court, the settling parties agreed to resolve the U.S. Class Action for an aggregate payment by the Company and its insurers of $21,000 to a settlement fund. On June 16, 2023, the parties filed a joint status report requesting that the Court grant a temporary stay of all proceedings in the case pending submission of proposed settlement documentation on or before July 13, 2023. On July 13, 2023, the plaintiffs filed an unopposed motion for an order preliminarily approving a stipulation of settlement agreed by the parties and providing for class notice which will provide for (i) preliminary approval of the settlement; (ii) approval of the form and manner of giving notice of the settlement to the settlement class; and (iii) a hearing date and time to consider final and approval of the Settlement and related matters “the “Preliminary Order”). On September 12, 2023, the plaintiffs filed an unopposed motion to amend the Preliminary Order to reflect certain changes to the form of release proposed to be executed by the plaintiffs.

The District Court issued its Preliminary Order on February 29, 2024, approving the proposed settlement. Consistent with the stipulation of settlement requiring that a settlement account be funded within 30 days of the Preliminary Order, the Company and its

Table of Contents

insurers have fully funded that account, with $1,403 funded by the Company and $19,597 funded by the Company’s insurers. The final fairness hearing is scheduled with the District Court for May 29, 2024.

By Notice of Action issued February 9, 2022, and subsequent Statement of Claim dated March 11, 2022, Izabela Przybylska (the "Plaintiff") commenced a putative class action against the Company, certain of its former officers, and others in the Ontario Superior Court of Justice on behalf of a purported class of all persons or entities, wherever they may reside or be domiciled, who acquired securities of the Company in both the primary and secondary markets during the period from October 28, 2020 until January 25, 2022 (the “Canadian Class Action”). The action asserts claims under Canadian securities legislation and at common law and seeks unspecified monetary damages and other relief in respect of allegations the defendants made false and misleading statements and omitted material information regarding the mineral resources and reserves of the Company.

On January 26, 2024, counsel for the Company and counsel for the Plaintiff executed a term sheet wherein any claims against us and the named individuals would be settled for a payment by the Company of $3,000. Such counsel subsequently agreed to and executed a definitive settlement agreement. On April 16, 2024, the Ontario Superior Court approved the settlement on a preliminary basis. Consistent with the terms of the settlement requiring that an escrow account be funded within 30 days of preliminary court approval, the Company and its insurers have fully funded an escrow account, with $2,597 funded by the Company and $403 funded by the Company’s insurers. The final fairness hearing is scheduled with the Ontario Superior Court for June 28, 2024.

Since the settlements of the U.S. Class Action and the Canadian Class Action are subject to conditions, including final court approvals, there can be no assurance that either the U.S. Class Action or the Canadian Class Action will be finally resolved pursuant to the agreements that have been reached.

Further, the Company has made disclosures to the U.S. Department of Justice and the SEC regarding its January 25, 2022 press release and issues related to Cerro Los Gatos’ mineral reserves and mineral resources at the time. The Company is cooperating with those agencies’ investigations and cannot reasonably predict any outcome.

There can be no assurance that any of the foregoing matters individually or in aggregate will not result in outcomes that are materially adverse for the Company.

Equipment Loan Agreements

The Company guaranteed the payment of all obligations, including accrued interest, under the LGJV equipment loan agreements. The LGJV equipment loan agreements were fully repaid on July 24, 2023.

11. Debt

On July 12, 2021, the Company entered into a Revolving Credit Facility (the “Credit Facility”). The Credit Facility contains affirmative and negative covenants that are customary for credit agreements of this nature. The affirmative covenants consist of a leverage ratio, a liquidity covenant and an interest coverage ratio. The negative covenants include, among other things, limitations on asset sales, mergers, acquisitions, indebtedness, liens, dividends and distributions, investments and transactions with affiliates. Obligations under the Credit Facility may be accelerated upon the occurrence of certain customary events of default. The Company was in compliance with all covenants under the Credit Facility as of September 30, 2023.

On December 13, 2023, the Company entered into a second amended and restated Credit Facility with BMO. The main changes to the terms of the agreement are as follows:

•the maturity date was extended to December 31, 2026;

•$50,000 revolving line of credit with an accordion feature, which allows for an increase in the total line of credit up to $100,000, subject to certain conditions;

•loans under the Credit Facility bear interest at a rate equal to either a term SOFR rate plus a margin ranging from 2.75% to 3.75%, or a U.S. base rate plus a margin ranging from 1.75% to 2.75%, at our option;

•Any drawdown is secured by the Company's assets including the Company's shares in the LGJV Entities.

For the three and nine months ended September 30, 2023, the Company recognized interest expense of $49 and $396, respectively, on the statements of income under other income, and $282 and $339, respectively, for amortization of debt issuance costs. The Company paid interest of $49 and $413, respectively, for the three and nine months ended September 30, 2023.

On July 21, 2023, the Company repaid the full outstanding balance of $9,000 on the Credit Facility. The Company has $50,000 available for withdrawal, with an accordion feature providing up to an additional $25,000.

13. Investment in Affiliates

During the three months ended September 30, 2023 and 2022, the Company recognized $9,437 and $8,930 of income, respectively, and during the nine months ended September 30, 2023 and 2022, the Company recognized $15,922 and $24,527 of income, respectively, on its investment in the LGJV, representing its ownership share of the LGJV results, including the effect of the priority distribution payment. The equity income or loss in affiliates includes amortization of the carrying value of the investment in excess of the underlying net assets of the LGJV. This basis difference is being amortized as the LGJV proven and probable reserves are processed.

On September 6, 2023, the Company reported an updated mineral reserve and mineral resource estimate and life of mine plan for the Cerro Los Gatos mine with an effective date of July 1, 2023. The mine life was extended by 2.75 years and significantly increased the mineral resource. This change in estimate has been applied prospectively, effective July 1, 2023, and resulted in a reduction of depletion, depreciation and amortizations expense of $4,331, and reduction in the deferred tax expense of $4,855 in the three and nine months period ended September 30, 2023.

On July 20, 2023, the LGJV made a $50,000 capital distribution to the LGJV partners, of which the Company’s share was $35,000.

In April and July 2022, the LGJV paid two dividends of $20,000 and $15,000 to its partners, respectively. The Company’s share of the first dividend was $14,000, before withholding taxes of $700. A payment of $7,365 was subsequently made to Dowa to cover the full amount of the reduced initial priority distribution due, for a net dividend received of $5,935. The Company's share of the second dividend was $9,975 before withholding taxes of $525.

The LGJV combined balance sheets as of September 30, 2023, and December 31, 2022, the combined statements of income for the three and nine months ended September 30, 2023 and 2022, and the statement of cash flows for the nine months ended September 30, 2023 and 2022 are as follows:

Restatement of previously issued Consolidated Financial Statements for the correction of the classification of capital distributions received from the LGJV on the Statements of Cash Flows

During the preparation of the financial statements for the three months ended March 31, 2024, the Company identified that the capital distributions received from its investment in affiliates classified as cash provided by investing activities on the Condensed Consolidated Statements of Cash Flows should have been classified as cash provided by operating activities. Based on management's judgement, the Company considered the declaration of the capital distribution (in its legal form) to be the nature of the activity that generated the cash flow and, therefore, classified the capital distribution as cash provided by investing activities on the Condensed Consolidated Statements of Cash Flows. On further analysis, it was determined that management should have considered the underlying source of the cash flow at the LGJV that generated the funds for the capital distribution when determining its classification on the Company's Condensed Consolidated Statements of Cash Flows. The capital distribution received previously classified as cash flow provided by investing activities should have been classified as cash flows provided by operating activities.

The impact of the correction of the misclassification on the financial statements of the Company is an increase in cash provided by operating activities of $35.0 million and a decrease in cash provided by investing activities of $35.0 million. There is no impact on the net increase in cash and cash equivalents or the balance of cash and cash equivalents at September 30, 2023. The Condensed Consolidated Balance Sheets and balance of cash and cash equivalents as of September 30,2023, and the Condensed Consolidated Statements of Income and Comprehensive Income and the Condensed Consolidated Statements of Shareholders’ Equity for the three and nine months ended September 30, 2023, are not affected by this change. The combined balance sheets, combined statements of income and the combined statements of cash flows of the LGJV included in the footnotes to the Company's financial statements are also not impacted by this change.

As discussed in the Explanatory Note to this Form 10-Q/A and in Note 3 to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q/A, we have restated the previously issued Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2023. The following discussion and analysis of our financial condition and results of operations incorporates the restated Condensed Consolidated Statement of Cash Flow amounts.

Operational highlights

Third Quarter 2023

•CLG produced 2.2 million ounces of silver, 9.5 million pounds of lead and 13.8 million pounds of zinc for the three months ended September 30, 2023, compared to 2.7 million ounces of silver, 12.2 million pounds of lead and 17.8 million pounds of zinc for the three months ended September 30, 2022. The lower production is primarily due to lower ore grades in 2023, as expected in the mine plan;

•Mill throughput equaled CLG's previous quarterly record, averaging 2,916 tonnes per day during the third quarter of 2023. The processing plant processed 268,312 tonnes, a 2% increase compared to 263,331 in the third quarter of 2022;

•The LGJV completed the construction of the zinc concentrate fluorine leach plant, which was commissioned in July 2023;

•On September 6, 2023, the Company reported an updated mineral reserve and mineral resource estimate and life of mine plan for the Cerro Los Gatos mine with an effective date of July 1, 2023. The mine life was extended by 2.75 years and significantly increased the mineral resource. On October 20, 2023, in support of the updated mineral reserve and mineral resource estimates, the Company filed a technical report summary prepared in accordance with subpart 1300 of Regulation S-K and a corresponding technical report prepared in accordance National Instrument 43-101 (collectively, the “2023 Technical Reports”);

•Exploration and definition drilling continued in the third quarter of 2023, with the focus on CLG mine life extension. A seventh surface drill rig has been mobilized to site, with five of these rigs continuing to be active on conversion drilling of the South-East Deeps inferred resource. The other two rigs will be focused on near mine exploration targets during the fourth quarter of 2023;

•Greenfields exploration work in the Los Gatos District continues to identify additional new high priority targets, including Lince, El Valle and San Luis.

Year to Date 2023

•CLG produced 6.65 million ounces of silver, 28.7 million pounds of lead and 42.7 million pounds of zinc for the nine months ended September 30, 2023, compared to 7.4 million ounces of silver, 34.2 million pounds of lead and 47.1 million pounds of zinc for the nine months ended September 30, 2022. The lower production is primarily due to lower ore grades in 2023, as expected in the mine plan;

•The processing plant processed 794,082 tonnes, an increase of 12% compared to 709,666 for the nine months ended September 30, 2022.

Financial highlights

Third Quarter 2023

•Revenue of $67.0 million for the three months ended September 30, 2023, decreased by 9% compared to the three months ended September 30, 2022, due to decreases in sales volumes and average realized zinc prices, partly offset by an increase in the average realized prices for silver, lead and gold;

•Cost of sales totaled $31.4 million for the three months ended September 30, 2023, an increase of 10% compared to the same period in 2022. The increase is primarily due to higher processing costs as a result of higher mill throughput and the strengthening of the Mexican peso against the U.S. dollar and inflationary cost pressures, partly offset by cost reduction initiatives as part of continuous improvement efforts;

•For the three months ended September 30, 2023, co-product all-in-sustaining cost per ounce of payable silver equivalent and by-product all-in-sustaining cost per ounce of payable silver increased to $17.64 and $14.71, respectively, compared to $13.13 and $10.04 for the three months ended September 30, 2022, respectively. The increases are primarily due to lower by-product credits (lead and zinc revenue);

•LGJV net income totaled $15.1 million in the three months ended September 30, 2023, compared to $13.0 million in the same period in 2022. Lower revenue for the quarter was offset by lower income tax expense and lower depreciation, depletion and amortization expense as a result of the increase in the mineral reserves and the extension of the life of the mine;

•EBITDA for the three months ended September 30, 2023, was $31.2 million, compared to $39.7 million in 2022, primarily due to lower revenue in the third quarter of 2023;

•Cash provided by operating activities was $29.4 million and $38.5 million for the three months ended September 30, 2023 and 2022, respectively. The $9.1 million decrease in cash provided by operating activities was primarily due to the decrease in revenue for the three months ended September 30, 2023, compared to the prior year period; and

LGJV

Three Months Ended September 30, 2023, Compared to Three Months Ended September 30, 2022

Revenue

The LGJV’s concentrate sales for the three months ended September 30, 2023 and 2022, are summarized below:


	Three Months Ended September 30,
(in thousands)	2023		2022
Lead concentrate revenue	$	54,141	$	53,619
Zinc concentrate revenue	14,522		21,426
Treatment and refining charges	(4,793)		(6,230)
Subtotal	63,870		68,815
Provisional revenue adjustments	3,168		5,111
Total Revenue	$	67,038	$	73,926

Revenue decreased by 9% for the three months ended September 30, 2023, compared to the three months ended September 30, 2022. The decrease in revenue is primarily due to decrease in sales volume of silver, zinc and lead of 23%, 19% and 27%, respectively, due to lower grades, and a decrease in the average realized zinc price of 29%, partly offset by an increase in average realized silver price and average realized lead price of 37% and 23%, respectively. Provisional revenue adjustments account for commodity price fluctuations in concentrate sales still subject to final settlement.

Cost of sales

Cost of sales increased by 10% primarily due to increased processing costs as a result of higher mill throughput, the strengthening of the Mexican peso against the U.S. dollar and inflationary cost pressures in the period, partly offset by cost reduction initiatives as part of continuous improvement efforts. Co-product cash cost per ounce of payable silver equivalent and by-product cash cost per ounce of payable silver for the three months ended September 30, 2023, increased to $14.42 and $10.04, respectively, primarily due to lower contribution from by-products.

Royalties

Royalty expense decreased by 9% for the three months ended September 30, 2023, compared to the same period in 2022 due to lower revenue in the third quarter of 2023.

General and administrative expenses

General and administrative expenses for the three months ended September 30, 2023, were $0.9 million higher as compared to the three months ended September 30, 2022, due to a $0.4 million increase in salaries, a $0.2 million increase in concession costs associated with changes in government regulations, a $0.2 million increase in the other expenses, the strengthening of the Mexican peso against the U.S. dollar and inflationary cost pressures in the period.

Depreciation, depletion and amortization

Depreciation, depletion, and amortization expense decreased by approximately 16% primarily due to the increase in mineral reserves and the extension of life of mine.. The reduced depreciation was partly offset by depreciation on the leaching plant commissioned in July 2023.

Exploration

Exploration expense for the three months ended September 30, 2023, was $0.9 million lower than in 2022, mainly due to reduced green-field exploration as the focus has been on the ongoing resource expansion drilling of the South-East Deeps zone at CLG.

Table of Contents

Other (income) expense

Other income of $0.9 million for the three months ended September 30, 2023, compared to other expense of $0.1 million for the three months ended September 30, 2022, was primarily due to interest income earned on higher cash balances, higher interest rates and an increase in account balances denominated in Mexican pesos, resulting in a gain on foreign exchange for the period.

Income tax (recovery) expense

An income tax recovery of $0.9 million was recorded for the three months ended September 30, 2023, compared to income tax expense of $6.7 million for the three months ended September 30, 2022. The recovery is due to the reduction in the valuation allowance on the deferred tax assets related to property plant and equipment and mine development as result of the increase in the mineral reserves and resources at CLG allowing for additional future income tax deductions to be realized.

Net income

For the three months ended September 30, 2023, the LGJV had net income of $15.1 million compared to $13.0 million for the three months ended September 30, 2022. The change in net income was primarily due to decrease in income tax expense, depreciation, depletion and amortization, exploration expense, a gain on foreign exchange and an increase in interest income earned, partly offset by a decrease in revenue, and an increase in cost of sales and general and administration expenses.

Sustaining capital

For the three months ended September 30, 2023, sustaining capital expenditures primarily consisted of $5.0 million on mine development and $4.0 million on infrastructure and equipment, including construction of a fluorine leach plant of $0.3 million, mine dewatering of $0.5 million, the construction of underground power distribution of $0.5 million, the construction of a ventilation raise of $0.2 million, and mining equipment of $2.1 million. During the three months ended September 30, 2022, sustaining capital expenditures primarily consisted of $7.1 million on mine development, $4.3 million on the construction of the paste-fill plant, $2.3 million on the construction of the raise of the tailings storage facility, $0.4 million on an underground power distribution infrastructure and $0.3 million on the construction of a ventilation raise

Resource development drilling expenditures

For the three months ended September 30, 2023, resource development drilling expenditures primarily related to resource expansion drilling of the South-East Deeps zone at CLG. There were no resource development drilling expenditures for the three months ended September 30, 2022.

Nine Months Ended September 30, 2023, Compared to Nine Months Ended September 30, 2022

Revenue

The LGJV’s concentrate sales for the nine months ended September 30, 2023 and 2022, are summarized below, in thousands:


	Nine Months Ended September 30,
(in thousands)	2023		2022
Lead concentrate revenue	$	169,085	$	164,706
Zinc concentrate revenue	52,519		77,404
Treatment and refining charges	(12,865)		(16,074)
Subtotal	208,739		226,036
Provisional revenue adjustments	(13,577)		(7,306)
Total Revenue	$	195,162	$	218,730

Revenue decreased by 11% for the nine months ended September 30, 2023, compared to the nine months ended September 30, 2022, primarily as a result of a decrease in sales volumes of silver and lead of 12% and 18%, respectively, due to lower grades, a decrease in average zinc price of 36%, partly offset by increase in realized average silver price of 22%. In addition, commodity prices decreased from period to period resulting in an unfavorable increase in the provisional revenue adjustment.

Provisional revenue adjustments account for commodity price fluctuations in concentrate sales still subject to final settlement.

Table of Contents

Cost of sales

Cost of sales increased by 2% primarily due to increasing processing costs as a result of higher mill throughput, the strengthening of the Mexican peso against the U.S. dollar and inflationary cost pressures in the period, partly offset by cost reduction initiatives as part of continuous improvement efforts. Co-product cash cost per ounce of payable silver equivalent and by-product cash cost per ounce of payable silver increased to $12.43 and $6.42, respectively, primarily due to lower contribution from by-products due to substantially lower realized zinc prices.

Royalties

Royalty expense decreased by $1.7 million for the nine months ended September 30, 2023, due to lower revenue and a reduction of the royalty percentage in June 2022, based on the terms of the royalty agreement.

General and administrative expenses

General and administrative expenses for the nine months ended September 30, 2023, were $2.8 million higher compared to the nine months ended September 30, 2022. The increase was primarily due to audit fees of $0.6 million, consulting fees of $0.3 million related to the restatement of 2021 annual and 2022 quarterly financial statements, $0.8 million increase in salaries, $0.5 million increase in insurance, $0.4 million increase in concessions costs associated with changes in government regulations and $0.2 million increase in the other expenses.

Depreciation, depletion and amortization

Depreciation, depletion, and amortization expense increased by 14% for the nine months ended September 30, 2023, as compared to the nine months ended September 30, 2022, primarily due to commissioning of the third tailing storage facility, the paste plant and the leaching plant in December 2022, March 2023 and July 2023, respectively. This increase was partly offset by the reduction in depreciation, depletion and amortization in the third quarter of 2023 related to the increase in mineral reserves and the extension of the life of the mine.

Exploration

Exploration expense for the nine months ended September 30, 2023, was $4.1 million lower as compared to the nine months ended September 30, 2022, primarily due to reduced green-field exploration, as the focus during the first nine months of 2023 was on the ongoing resource expansion drilling of the South-East Deeps Zone at CLG.

Other (income) expense

Other income was $1.8 million for the nine months ended September 30, 2023, compared to other expense of $1.1 million for the nine months ended September 30, 2022. The increase in other income was primarily due to interest income earned on higher cash balances and higher interest rates and an increase in account balances denominated in Mexican pesos, resulting in a gain on foreign exchange for the period.

Income tax (recovery) expense

Income tax expense decreased by $12.7 million for the nine months ended September 30, 2023, compared to September 30, 2022, primarily due to the reduction in the valuation allowance on the deferred tax assets related to property plant and equipment and mine development as a result of the increase in the mineral reserves and resources at CLG allowing for additional future income tax deductions to be realized.

Net income

For the nine months ended September 30, 2023, the LGJV had net income of $28.5 million compared to $42.4 million for the nine months ended September 30, 2022. The decrease in net income was primarily due to a decrease in revenues and increases in cost of sales, depreciation, depletion and amortization, and general and administrative expenses, partly offset by decreases in income tax expense, royalties, exploration, an increased gain on foreign exchange and interest income.

Table of Contents

Sustaining capital

For the nine months ended September 30, 2023, sustaining capital expenditures primarily consisted of $16.2 million on mine development and $13.6 million on infrastructure and equipment including construction of a fluorine leach plant of $3.6 million, construction of ventilation raise of $0.6 million, underground power distribution of $1.1 million, mine dewatering of $1.9 million and mining equipment of $5.3 million.

The following table presents summarized information relating to the Company’s cash flows for the nine months ended September 30, 2023 and 2022.


	Nine Months Ended September 30,
(in thousands)	2023		2022
Net cash provided (used) by
Operating activities	$	25,465	$	8,680
Investing activities	—		(27)
Financing activities	(9,000)		—
Total change in cash	$	16,465	$	8,653
Cash and cash equivalents, beginning of period	$	17,004	$	6,616
Cash and cash equivalents, end of period	$	33,469	$	15,269

The cash balance at September 30, 2023, increased to $33.5 million from $17.0 million at December 31, 2022.

For the nine months ended September 30, 2023, $25.5 million of cash was provided by operating activities, compared to $8.7 million provided by operating activities in the nine months ended September 30, 2022, largely due to a $35.0 million capital distribution received in 2023, compared to a $15.9 million net dividend received from the LGJV in the nine months ended September 30, 2022.

For the nine months ended September 30, 2023, there was no cash flow from investing activities.

Free cash flow for nine months ended September 30, 2023 increased to $25.5 million from $8.7 million for nine months ended September 30, 2022, primarily due to the receipt of a capital distribution from LGJV on July 20, 2023.

Cash used by financing activities for the nine months ended September 30, 2023, of $9.0 million represents the repayment of the outstanding balance of the Credit Facility on July 21, 2023.

LGJV

The following table presents summarized information relating to the LGJV’s cash flows for the nine months ended September 30, 2023 and 2022.


	Nine Months Ended September 30,
(in thousands)	2023		2022
Net cash provided (used) by
Operating activities	$	103,789	$	120,000
Investing activities	(41,160)		(61,903)
Financing activities	(50,532)		(39,712)
Total change in cash	$	12,097	$	18,385
Cash and cash equivalents, beginning of period	$	34,936	$	20,280
Cash and cash equivalents, end of period	$	47,033	$	38,665

The LGJV cash balance at September 30, 2023 increased to $47.0 million, from $34.9 million at December 31, 2022.

Cash provided by operating activities was $103.8 million and $120.0 million for the nine months ended September 30, 2023 and 2022, respectively. The $16.2 million decrease in cash provided by operating activities was primarily due to the decrease in revenue for the nine months ended September 30, 2023, compared to the prior year period.

Cash used by investing activities was $41.2 million and $61.9 million for the nine months ended September 30, 2023 and 2022, respectively. In the nine months ended September 30, 2023, $13.5 million were property, plant and equipment expenditures and $27.2 million were mine development expenditures, of which $10.5 million was associated with capitalized development drilling. In the nine months ended September 30, 2022, $28.8 million was property, plant and equipment expenditures and $32.8 million was mine development expenditures. e

The LGJV’s free cash flow for the nine months ended September 30, 2023, was $62.6 million, compared to $58.1 million in the comparable period of 2022. Lower revenues for the nine months ended September 30, 2023, was more than offset by lower capital expenditures, resulting in the increase in free cash flow in 2023.

Cash used by financing activities was $50.5 million and $39.7 million for the nine months ended September 30, 2023 and 2022, respectively. The $50.5 million use of cash was primarily due to the capital distribution of $50.0 million to the LGJV partners in July 2023, compared to $35.0 million dividend payments made during the nine months ended September 30, 2022.

Liquidity and Capital Resources

As of September 30, 2023, and December 31, 2022, the Company had cash and cash equivalents of $33.5 million and $17.0 million, respectively. The increase in cash and cash equivalents of $16.5 million is due to a $35.0 million capital distribution received from the LGJV in 2023, partly offset by the $9.0 million repayment of the outstanding balance of the Credit Facility on July 21, 2023 and general and administrative expenses incurred in the period. The Company has $50.0 million available to be drawn under the Credit Facility.

As at April 30, 2024, our cash and cash equivalents are $85.4 million and we have $50.0 million available to be drawn under the Credit Facility. The LGJV had cash and cash equivalents of $20.0 million as at April 30, 2024. On October 30, 2023, February 15 and April 22, 2024, the LGJV made a $35.0 million, a $30.0 million and a $25.0 million capital distribution to the LGJV partners, respectively, of which the Company’s share was $24.5 million, $21.0 million and $17.5 million, respectively. We believe the Company has sufficient cash and access to borrowings and other resources to carry out its business plans for at least the next 12 months. The Company manages liquidity risk through the Credit Facility and the management of its capital structure.

Contractual Obligations

There have been no changes from the contractual obligations described in our 2022 10-K.

Critical Accounting Policies

Please refer to Note 2 Summary of Significant Accounting Policies in our condensed consolidated financial statements included in this Report and the 2022 10-K for discussion of our critical accounting policies and estimates.

Jumpstart Our Business Startups Act of 2012

The Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) permits us, as an “emerging growth company,” to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We have elected to “opt out” of this provision and, as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for public companies that are not emerging growth companies. The decision to opt out of the extended transition period under the JOBS Act is irrevocable.

Non-GAAP Financial Measures

We use certain measures that are not defined by GAAP to evaluate various aspects of our business. These non-GAAP financial measures are intended to provide additional information only and do not have any standardized meaning prescribed by GAAP and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. The measures are not necessarily indicative of operating profit or cash flow from operations as determined under GAAP.

Cash Costs and All-In Sustaining Costs

Cash costs and all-in sustaining costs (“AISC”) are non-GAAP measures. AISC was calculated based on guidance provided by the World Gold Council (“WGC”). WGC is not a regulatory industry organization and does not have the authority to develop accounting standards for disclosure requirements. Other mining companies may calculate AISC differently as a result of differences in underlying accounting principles and policies applied, as well as definitional differences of sustaining versus expansionary (i.e. non-sustaining) capital expenditures based upon each company’s internal policies. Current GAAP measures used in the mining industry, such as cost of sales, do not capture all of the expenditures incurred to discover, develop and sustain production. Therefore, we believe that cash costs and AISC are non-GAAP measures that provide additional information to management, investors and analysts that aid in the understanding of the economics of the Company’s operations and performance compared to other producers and provides investors visibility by better defining the total costs associated with production.

Cash costs include all direct and indirect operating cash costs related directly to the physical activities of producing metals, including mining, processing and other plant costs, treatment and refining costs, general and administrative costs, royalties and mining production taxes. AISC includes total production cash costs incurred at the LGJV’s mining operations plus sustaining capital expenditures. The Company believes this measure represents the total sustainable costs of producing silver from current operations and provides additional information of the LGJV’s operational performance and ability to generate cash flows. As the measure seeks to reflect the full cost of silver production from current operations, new project and expansionary capital at current operations are not included. Certain cash expenditures such as new project spending, tax payments, dividends, and financing costs are not included.

Reconciliation of expenses (GAAP) to non-GAAP measures (Cash Costs and All-In Sustaining Costs)

The table below presents a reconciliation between the most comparable GAAP measure of the LGJV’s expenses to the non-GAAP measures of (i) cash costs, (ii) cash costs, net of by-product credits, (iii) co-product AISC and (iv) by-product AISC for our operations.

Payable silver equivalents utilize the average realized prices during the nine months ended September 30, 2022, of $20.48/oz silver, $1.73/lb zinc, $0.90/lb lead and $1,708/oz gold and the average realized prices during the three months ended September 30, 2022, of $17.69/oz silver, $1.25/lb zinc, $0.79/lb lead and $1,682/oz gold. Realized prices include the impact of final settlement adjustments from prior period sales.

5.Sustaining capital excludes resource development drilling costs related to resource development drilling of the South- East Deeps zone.

The Company does not provide a reconciliation of forward-looking co-product and by-product AISC guidance, due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliation.

EBITDA

Management uses EBITDA to evaluate the Company’s operating performance, to plan and forecast its operations, and assess leverage levels and liquidity measures. The Company believes the use of EBITDA reflects the underlying operating performance of our core mining business and allows investors and analysts to compare results of the Company to similar results of other mining companies. EBITDA does not represent, and should not be considered an alternative to, net income or cash flow from operations as determined under GAAP. The table below reconciles EBITDA, a non-GAAP measure to Net Income:


	Three Months Ended September 30,				Nine Months Ended September 30,
(in thousands)	2023		2022		2023		2022

Free Cash Flow

Management uses Free Cash Flow as a non-GAAP measure to analyze cash flows generated from operations. Free Cash Flow is Cash provided by (used in) operating activities less Cash Flow (used in) from investing Activities as presented on the Condensed Consolidated Statements of Cash Flows. The Company believes Free Cash Flow is also useful for investors as one of the bases for comparing the Company’s performance with its competitors. Although Free Cash Flow and similar measures are frequently used as measures of cash flows generated from operations by other companies, the Company’s calculation of Free Cash Flow is not necessarily comparable to such other similarly titled captions of other companies.

The following table sets forth a reconciliation of Free Cash Flow, a non-GAAP financial measure, to net cash (used) provided by operating activities, which the Company believes to be the GAAP financial measure most directly comparable to Free Cash Flow.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are a smaller reporting company and are not required to provide disclosure pursuant to this Item.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We have established disclosure controls and procedures, as such term is defined in Rule 13a-15(e) under the Exchange Act, that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our principal executive and principal financial officers as appropriate, to allow timely decisions regarding required disclosure.

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2023. Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were not effective as of September 30, 2023, due to the material weaknesses in our internal control over financial reporting described in the 2022 10-K and the material weakness in our internal control over financial reporting described below.

In connection with our review of the internal control structure related to the preparation of the restated financial statements for the nine months ended September 30, 2023, and the year ended December 31, 2023, we have identified a material weakness in our internal controls over financial reporting relating to the failure to design and maintain effective controls to ensure the accurate classification of distributions from our investment in affiliates in the Consolidated Statement of Cash Flows.

Changes in Internal Control over Financial Reporting

During the quarter ended September 30, 2023, control and procedure enhancements were performed over the preparation and review of the 2023 mineral reserves and mineral resource estimates. Management is evaluating the effectiveness of these controls. We also identified that we failed to design and maintain effective controls to ensure the accurate classification of distributions from our investment in affiliate on the Consolidated Statements of Cash Flows. There have not been any other changes in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended September 30, 2023, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Limitations on Effectiveness of Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, do not expect that our disclosure controls and procedures will prevent all errors and fraud. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable, not absolute, assurance of achieving the desired control objectives. Further, the design of a control system must reflect resource constraints, which require management to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management’s override of the control.

Table of Contents

The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

For a description of Legal Proceedings see Note 9. Commitments, Contingencies and Guarantees in Item 1. Financial Statements.

Item 1A. Risk Factors

Factors that could cause our actual results to differ materially from those in this Report include, but are not limited to, any of the risks described in the 2022 10-K. Any of these factors could result in a significant or material adverse effect on our results of operations or financial condition. Additional risk factors not currently known to us or that we currently deem immaterial may also adversely affect us. As of the date of this Report, there have been no material changes to the risk factors disclosed in the 2022 10-K.

Based on management's judgement, the Company considered the declaration of the capital distribution (in its legal form) to be the nature of the activity that generated the cash flow and, therefore, classified the capital distribution as cash provided by investing activities on the Condensed Consolidated Statements of Cash Flows. On further analysis, it was determined that management should have considered the underlying source of the cash flow at the LGJV that generated the funds for the capital distribution when determining its classification on the Company's Condensed Consolidated Statements of Cash Flows. The capital distribution received previously classified as cash flow provided by investing activities should have been classified as cash flows provided by operating activities. The Condensed Consolidated Balance sheets and balance of cash and cash equivalents as of September 30, 2023, and the Condensed Consolidated Statements of Income and Comprehensive Income and the Condensed Consolidated Statements of Shareholders’ Equity for the three and nine months ended September 30, 2023, are not impacted by this change. See Note 3. Restatement of Previously Issued Financial Statements to the condensed consolidated financial statements included herein for additional information.This Amendment No. 1 contains the following sections:•Item 1. Financial Statements•Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations•Item 4. Controls and Procedures•Exhibits 31, 32, 101 and 104 of Item 6. Exhibits.Except as described above, and as further described in Note 3 to the condensed consolidated financial statements in this Form 10-Q/A, this Amendment No. 1 does not amend, update or change any other items or disclosures contained in the Original Filing, and accordingly, this Amendment No. 1 does not reflect or purport to reflect any information or events occurring after the original filing date or modify or update those disclosures affected by subsequent events. Accordingly, this Amendment No. 1 should be read in conjunction with the Original Filing and the Company’s other filings with the SEC. Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Original Filing.

There have been no material changes to, or in the application of, the accounting policies previously identified and described in the 2022 10-K. Recent Accounting Pronouncements In October 2023, the FASB issued ASU No. 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative. The amendments in this update modify the disclosure or presentation requirements of a variety of Topics in the Codification. Certain amendments represent clarifications to or technical corrections of the current requirements. Each amendment in the ASU will only become effective if the SEC removes the related disclosure or presentation requirement from its existing regulations by June 30, 2027. The Company is still assessing the impact of the standard. There have been no other accounting pronouncements issued or adopted during the nine months ended September 30, 2023, which are expected to have a material impact on the financial statements.

Fair Value Measurements	Sep. 30, 2023
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company establishes a framework for measuring the fair value of assets and liabilities in the form of a fair value hierarchy that prioritizes the inputs into valuation techniques used to measure fair value into three broad levels. This hierarchy gives the highest priority to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs. Further, financial assets and liabilities should be classified by level in their entirety based upon the lowest level of input that was significant to the fair value measurement. The three levels of the fair value hierarchy are as follows: Level 1: Unadjusted quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date. Level 2: Quoted prices in inactive markets for identical assets or liabilities, quoted prices for similar assets or liabilities in active markets, or other observable inputs either directly related to the asset or liability or derived principally from corroborated observable market data. Level 3: Unobservable inputs due to the fact there is little or no market activity. This entails using assumptions in models which estimate what market participants would use in pricing the asset or liability. Assets and Liabilities that are Measured at Fair Value on a Non-recurring Basis The Company discloses and recognizes its non-financial assets and liabilities at fair value on a non-recurring basis and makes adjustments to fair value, as needed (for example, when there is evidence of impairment). The Company recorded its initial investment in affiliates at fair value within Level 3 of the fair value hierarchy, as the valuation was determined based on internally developed assumptions with few observable inputs and no market activity.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Guarantees	Commitments, Contingencies and Guarantees In determining its accruals and disclosures with respect to loss contingencies, the Company will charge to income an estimated loss if information available prior to the issuance of the financial statements indicates that it is probable that a liability has been incurred at the date of the financial statements and the amount of the loss can be reasonably estimated. Legal expenses associated with the commitments and contingencies are expensed as incurred. If a loss contingency is not probable or reasonably estimable, disclosure of the loss contingency is made in the financial statements when it is at least reasonably possible that a material loss could be incurred. Environmental Contingencies The Company’s mining and exploration activities are subject to various laws, regulations and permits governing the protection of the environment. These laws, regulations and permits are continually changing and are generally becoming more restrictive. The Company has made, and expects to make in the future, expenditures to comply with such laws, regulations and permits, but cannot predict the full amount of such future expenditures. Legal On February 22, 2022, a purported Company stockholder filed a putative class action lawsuit in the United States District Court for the District of Colorado (the "District Court") against the Company, certain of our former officers, and several directors (the "U.S. Class Action"). An amended complaint was filed on August 15, 2022. The amended complaint, allegedly brought on behalf of certain purchasers of the Company’s common stock and certain traders of call and put options on the Company’s common stock from December 9, 2020 through January 25, 2022, seeks, among other things, damages, costs, and expenses, and asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 as well as Sections 11 and 15 of the Securities Act of 1933. The amended complaint alleges that certain individual defendants and the Company, pursuant to the control and authority of the individual defendants, made false and misleading statements and/or omitted certain material information regarding the mineral resources and reserves at the Cerro Los Gatos mine. The Company and all defendants filed a motion to dismiss this action on October 14, 2022. That motion was fully briefed as of December 23, 2022. On April 26, 2023, following a joint motion, the Court postponed its ruling on the defendants’ motion to dismiss until on or after June 16, 2023. On June 13, 2023, the Company entered into an agreement in principle to settle the U.S. Class Action. Subject to certain conditions, including class certification by the District Court, the execution of a definitive stipulation of settlement and approval of the settlement by the District Court, the settling parties agreed to resolve the U.S. Class Action for an aggregate payment by the Company and its insurers of $21,000 to a settlement fund. On June 16, 2023, the parties filed a joint status report requesting that the Court grant a temporary stay of all proceedings in the case pending submission of proposed settlement documentation on or before July 13, 2023. On July 13, 2023, the plaintiffs filed an unopposed motion for an order preliminarily approving a stipulation of settlement agreed by the parties and providing for class notice which will provide for (i) preliminary approval of the settlement; (ii) approval of the form and manner of giving notice of the settlement to the settlement class; and (iii) a hearing date and time to consider final and approval of the Settlement and related matters “the “Preliminary Order”). On September 12, 2023, the plaintiffs filed an unopposed motion to amend the Preliminary Order to reflect certain changes to the form of release proposed to be executed by the plaintiffs. The District Court issued its Preliminary Order on February 29, 2024, approving the proposed settlement. Consistent with the stipulation of settlement requiring that a settlement account be funded within 30 days of the Preliminary Order, the Company and its insurers have fully funded that account, with $1,403 funded by the Company and $19,597 funded by the Company’s insurers. The final fairness hearing is scheduled with the District Court for May 29, 2024. By Notice of Action issued February 9, 2022, and subsequent Statement of Claim dated March 11, 2022, Izabela Przybylska (the "Plaintiff") commenced a putative class action against the Company, certain of its former officers, and others in the Ontario Superior Court of Justice on behalf of a purported class of all persons or entities, wherever they may reside or be domiciled, who acquired securities of the Company in both the primary and secondary markets during the period from October 28, 2020 until January 25, 2022 (the “Canadian Class Action”). The action asserts claims under Canadian securities legislation and at common law and seeks unspecified monetary damages and other relief in respect of allegations the defendants made false and misleading statements and omitted material information regarding the mineral resources and reserves of the Company. On January 26, 2024, counsel for the Company and counsel for the Plaintiff executed a term sheet wherein any claims against us and the named individuals would be settled for a payment by the Company of $3,000. Such counsel subsequently agreed to and executed a definitive settlement agreement. On April 16, 2024, the Ontario Superior Court approved the settlement on a preliminary basis. Consistent with the terms of the settlement requiring that an escrow account be funded within 30 days of preliminary court approval, the Company and its insurers have fully funded an escrow account, with $2,597 funded by the Company and $403 funded by the Company’s insurers. The final fairness hearing is scheduled with the Ontario Superior Court for June 28, 2024. Since the settlements of the U.S. Class Action and the Canadian Class Action are subject to conditions, including final court approvals, there can be no assurance that either the U.S. Class Action or the Canadian Class Action will be finally resolved pursuant to the agreements that have been reached. Further, the Company has made disclosures to the U.S. Department of Justice and the SEC regarding its January 25, 2022 press release and issues related to Cerro Los Gatos’ mineral reserves and mineral resources at the time. The Company is cooperating with those agencies’ investigations and cannot reasonably predict any outcome. There can be no assurance that any of the foregoing matters individually or in aggregate will not result in outcomes that are materially adverse for the Company. Equipment Loan Agreements The Company guaranteed the payment of all obligations, including accrued interest, under the LGJV equipment loan agreements. The LGJV equipment loan agreements were fully repaid on July 24, 2023.

The Credit Facility contains affirmative and negative covenants that are customary for credit agreements of this nature. The affirmative covenants consist of a leverage ratio, a liquidity covenant and an interest coverage ratio. The negative covenants include, among other things, limitations on asset sales, mergers, acquisitions, indebtedness, liens, dividends and distributions, investments and transactions with affiliates. Obligations under the Credit Facility may be accelerated upon the occurrence of certain customary events of default. The Company was in compliance with all covenants under the Credit Facility as of September 30, 2023.

The main changes to the terms of the agreement are as follows: •the maturity date was extended to December 31, 2026; •$50,000 revolving line of credit with an accordion feature, which allows for an increase in the total line of credit up to $100,000, subject to certain conditions; •loans under the Credit Facility bear interest at a rate equal to either a term SOFR rate plus a margin ranging from 2.75% to 3.75%, or a U.S. base rate plus a margin ranging from 1.75% to 2.75%, at our option; •Any drawdown is secured by the Company's assets including the Company's shares in the LGJV Entities. For the three and nine months ended September 30, 2023, the Company recognized interest expense of $49 and $396, respectively, on the statements of income under other income, and $282 and $339, respectively, for amortization of debt issuance costs.

On July 21, 2023, the Company repaid the full outstanding balance of $9,000 on the Credit Facility.

Summary of Significant Accounting Policies (Policies)	Sep. 30, 2023
Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In October 2023, the FASB issued ASU No. 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative. The amendments in this update modify the disclosure or presentation requirements of a variety of Topics in the Codification. Certain amendments represent clarifications to or technical corrections of the current requirements. Each amendment in the ASU will only become effective if the SEC removes the related disclosure or presentation requirement from its existing regulations by June 30, 2027. The Company is still assessing the impact of the standard. There have been no other accounting pronouncements issued or adopted during the nine months ended September 30, 2023, which are expected to have a material impact on the financial statements.
Fair Value Measurements	The Company establishes a framework for measuring the fair value of assets and liabilities in the form of a fair value hierarchy that prioritizes the inputs into valuation techniques used to measure fair value into three broad levels. This hierarchy gives the highest priority to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs. Further, financial assets and liabilities should be classified by level in their entirety based upon the lowest level of input that was significant to the fair value measurement. The three levels of the fair value hierarchy are as follows: Level 1: Unadjusted quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date. Level 2: Quoted prices in inactive markets for identical assets or liabilities, quoted prices for similar assets or liabilities in active markets, or other observable inputs either directly related to the asset or liability or derived principally from corroborated observable market data. Level 3: Unobservable inputs due to the fact there is little or no market activity. This entails using assumptions in models which estimate what market participants would use in pricing the asset or liability. Assets and Liabilities that are Measured at Fair Value on a Non-recurring Basis The Company discloses and recognizes its non-financial assets and liabilities at fair value on a non-recurring basis and makes adjustments to fair value, as needed (for example, when there is evidence of impairment). The Company recorded its initial investment in affiliates at fair value within Level 3 of the fair value hierarchy, as the valuation was determined based on internally developed assumptions with few observable inputs and no market activity.
