First Phosphate Chooses Facility in Saguenay-Lac-St-Jean, Quebec, Canada for Deployment of its Iron Phosphate Plant

Saguenay, Quebec--(Newsfile Corp. - September 9, 2024) - First Phosphate Corp (CSE: PHOS) (OTC: FRSPF) (FSE: KD0) ("First Phosphate" or the "Company") is pleased to announce that it has secured a facility lease for a 10,000 tonne per annum iron phosphate cathode active material pre-cursor ("pCAM") plant ("First Saguenay") in Saguenay (La Baie), Quebec, Canada.

Iron phosphate is a key pre-cursor used in the production of cathode active material ("CAM") for lithium iron phosphate ("LFP") batteries.

Local Support and Job Creation in Saguenay-Lac-St-Jean, Quebec, Canada

The establishment of the First Saguenay plant is intended to lead to the creation of approximately one hundred new high-tech jobs in the Saguenay-Lac-St-Jean Region of Quebec, Canada. The development of First Saguenay is supported by a number of local parties in the region's economic development landscape including:

• Promotions Saguenay (economic development corporation for the city of Saguenay)

• Saguenay-Le Fjord Chamber of Commerce and Industry (CCISF)

• Alliage 02 (Saguenay-Lac-Saint-Jean Manufacturers and Industrial Parks Corporation)

• Saguenay-Lac-St-Jean Economic Maximization Committee (CMAX)

• Pekuakamiulnuatsh First Nation (Mashteuiatsh)

"This announcement is another very positive step for phosphate mining in our region, and the start of the LFP sector in Saguenay-Lac-St-Jean, Quebec," states Ms. Andrée Laforest, deputy for the Quebec riding of Chicoutimi, Quebec Minister of Municipal Affairs and Minister responsible for the Saguenay-Lac-Saint-Jean region. "We've been talking about this potential for a long time, and we're finally seeing the efforts of the First Phosphate team come to fruition today and for years to come. The Company's regional production will have positive effects for us and for Port Saguenay, which will be a major player in the development of this sector."

"This plant is the first link in the LFP Battery Valley in Saguenay-Lac-St-Jean," emphasizes Éric Larouche, Chairman of the Board of Promotion Saguenay. "Our goal is to facilitate the creation of this North American value chain, right here at home in Saguenay-Lac-St-Jean, Quebec: from the phosphate mine, to LFP cathode powder and, eventually, to the LFP battery itself."

"This commitment with First Phosphate today sends a clear signal about our potential to position within the battery ecosystem: home-grown raw material and an international shipping corridor. The builders in our region will assume their role in global decarbonization efforts," emphasizes François Tremblay, Quebec Member of Parliament for Dubuc.

An important First Step in Establishing First Phosphate Downstream Operations in Saguenay-Lac-St-Jean, Quebec, Canada

First Saguenay is to be retrofitted into a large portion of the existing building at 5373 Chemin Saint-Anicet, La Baie, Quebec, adjacent to the existing processing plant owned by Logistique Proco Inc. ("Proco"). Proco is to act as the building contractor. Proco is well established in the engineering and construction sector in Quebec, having worked on major projects in the province and, many, specifically in the battery sector (https://www.proco.ca/fr/realisations). The First Saguenay lease with Proco is for 10 years and is renewable thereafter.

The facility is heated, equipped with process water, wastewater treatment, natural gas, high-voltage electricity and served by direct North American rail link into the facility. Moreover, the entire facility occupies more than 305,000 square feet of industrial space, portions of which should become available progressively for expanded First Saguenay operations, as well as several hectares of adjacent green-field industrial land available for expanding operations.

The investment needed for the commencement of operations at First Saguenay is estimated at approximately USD $65 M (CAD $90 M). The lease is conditional upon First Phosphate arranging the financing necessary to carry-out the proposed activities prior to April 30, 2025. First Phosphate is considering various options for financing and structuring First Saguenay including non-dilutive options.

An important First Step in Establishing the North American LFP Battery Valley in Saguenay-Lac-St-Jean, Quebec, Canada

First Saguenay is to serve as a key and complimentary part of the Company's planned downstream processing facilities and full vertical integration plans from phosphate mine to creation of LFP CAM. First Saguenay is intended to work synergistically in the transformation and value-added processing of the feedstock from the Company's proposed mining operations which are located approximately 80 km and 120 km from the Company's two major phosphate properties in the region.

First Saguenay has a strategic logistical advantage located at 20 km from the deep-sea port of Saguenay, where the Company intends to organize the next phases of its industrial activities, as well as its inbound and outbound international trade. The industrial zone at Port Saguenay will become an important location in the development of the LFP battery industry, and First Phosphate plans to set up its future advanced processing operations at the port together with other worldwide LFP battery players.

First Saguenay is also positioned at a few kilometers from Canadian Air Forces NATO Base Bagotville and its local airport providing passenger and freight linkages to the world.

First Saguenay is to be linked directly and seamlessly to the Canadian National Railway network which connects directly to other railway networks across North America for easy entry of supplies and delivery of product to clients across the North American battery industry.

Details of First Phosphate's strategy to create a fully integrated supply chain for LFP batteries in North America, based on the establishment of the Saguenay-Lac-St-Jean region of Quebec, Canada as the LFP battery valley of North America, can be found at: https://firstphosphate.com/fr/lfp-battery-strategy.

Feasibility and Client Relationships

The Company has begun the first phase of its project feasibility study with Ultion Technologies ("Ultion"), a US-based company that is a pioneer in the LFP battery industry. The study is to determine the infrastructure required to support the permit applications as well as the lease facility retrofitting requirements.

The technology to be implemented is proven and already operating in two other facilities in the world, one with a capacity of 10,000 tonnes per annum and another with a capacity of 50,000 tonnes per annum, as announced on December 11, 2023 (https://firstphosphate.com/ultion-technologies-mou). Thanks to the industrial capacity of the chosen technology, First Saguenay expects to be able to move directly into commercial-size, scalable production without having to go through a pilot stage.

Initial production from First Saguenay is anticipated for the first quarter of 2026 to meet anticipated demand from the Company's existing partners: American Battery Factory (https://firstphosphate.com/abf), Ultion (https://firstphosphate.com/ultion-technologies-mou and other potential clients in the fields of energy storage, electric vehicles and specialized battery products with which the Company is in advanced discussions.

The commencement of operations at First Saguenay entails meeting a number of project requirements. The Company is working diligently through the process to satisfy all such requirements.
