First Phosphate Announces Positive Results of

Preliminary Economic Assessment at its Bégin-Lamarche
Property in Saguenay-Lac-Saint-Jean, Quebec, Canada

NOT INTENDED FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR THE UNITED STATES

Saguenay, Quebec – December 4, 2024 – First Phosphate Corp. (“First Phosphate” or the “Company”) (CSE:PHOS) (OTCQB: FRSPF) (FSE:KD0) is pleased to announce the positive results of its Preliminary Economic Assessment (“PEA”) on the Bégin-Lamarche Property (the “Property” or the “Project”) located 75 km northwest of Saguenay, Quebec, Canada.

The PEA provides a potentially viable case for developing the Property by open pit mining for the primary production of phosphate concentrate and secondary bi-product recovery of magnetite concentrate.

Highlights (all dollar amounts in Canadian dollars on a 100% project ownership basis unless otherwise indicated):

The Project would produce an annual average of 900,000 tonnes of beneficiated phosphate concentrate at 40% P₂O₅ content and 380,000 tonnes of magnetite at 92% Fe₂O₃content over a 23-year mine life.

The Project generates a pre-tax internal rate or return (IRR) of 37.1% and a pre-tax net present value (NPV) of $2.100 Billion at an 8% discount rate at an approximate 3-year trailing average phosphate price plus a premium for purity and potential secure source of supply, and a 2-year trailing average magnetite price plus a premium for purity.

The Project generates an after-tax internal rate or return (IRR) of 33.0% and an after-tax net present value (NPV) of $1.590 Billion at an 8% discount rate.

The Project would generate an after-tax cash flow of $700 Million in years 1 to 3, resulting in a 2.9-year payback period from start of production. Pre-tax cash flow in years 1 to 3 is $783 Million for a 2.6-year payback period.

The Project benefits from adjacent paved provincial road access and nearby electrical power line, and year-round accessible deep-sea Port of Saguenay at approximately 85 km driving distance. Initial capex for the Project is limited to $675 million.

The PEA used Indicated and Inferred Mineral Resources in its calculations.

The Project has no outstanding royalties or financing streams registered against it.

“We are pleased with the results and timely completion of this PEA. Existing local infrastructure keeps our capex low, our mine size controlled and our mine economics robust,” says First Phosphate CEO, John Passalacqua. “Our internal Pre-Feasibility work is also near completion and we are now in a position to determine the timing on our Feasibility Study.”

1. Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability.

2. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation socio-political, marketing, or other relevant issues.

3. The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.

4. The Mineral Resources were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices Guidelines (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council.

The mine plan uses conventional truck/shovel open pit methods utilizing 90-tonne capacity haulage trucks and shovels equipped with 10 cubic metre buckets. The open pit will be mined over a period of 22 production years and six months of pre-stripping. Low-grade mineralization that is stockpiled over the life-of-mine will be processed for an additional production year. Mineralized material will be transported by haulage trucks to the nearby process plant, and waste rock will be stored at a facility located approximately 800 metres southeast of the open pit. Backfilling of the mined-out open pit with 61 Mt of waste rock is planned, which will reduce the amount required to be stored on surface and lead to proactive restorative measures. Mining is to be conducted at an initial rate of 15 Million total tonnes per annum (Mtpa), and will reach a peak of 28 Mtpa based on process plant feed and waste rock removal requirements.

The process plant feed is contained within an optimized subset of the Mineral Resource set out in the table above. The open pit contains 150.5 Mt of process plant feed (inclusive of mining dilution and loss factors) averaging 5.76% P₂O₅ and 10.32% Fe₂O₃. The process plant feed is associated with 219 Mt of waste rock and overburden resulting in an overall life-of-mine strip ratio of 1.5:1. It is notable that all Mineral Resources considered for mining are in the Indicated and Inferred classifications.

Extensive metallurgical testing was carried out at SGS, Quebec City. The test work has indicated process recoveries of phosphate and magnetite to be reasonably high and relatively consistent. The most recent tests focused on circuit stability and maximizing concentrate recovery. Elements of potential concern in traditional phosphate operations based on sedimentary phosphate deposits used for fertilizers are not an issue since the Bégin-Lamarche Mineral Resource is based on a clean igneous rock deposit. Moreover, the low sulphur content suggests the tailings material would not create an environmental risk for acid generation or for metal leaching. Lastly, dry stack tailings and waste rock management are designed for closure and the elimination of concerns for acid drainage or metal leaching.
