First Phosphate Reports Published Research Studies for its Lac à l'Orignal, Mirepoix and Bégin-Lamarche Properties in the Saguenay-Lac-St-Jean region of Quebec, Canada

Saguenay, Quebec--(Newsfile Corp. - March 26, 2024) - First Phosphate Corp. (CSE: PHOS) (OTC: FRSPF) (FSE: KD0) ("First Phosphate" or the "Company"), is pleased to announce that two peer-reviewed publications in scientific journals and one research report have been published on its phosphate properties at Lac à l'Orignal, Mirepoix and Bégin-Lamarche in the Saguenay-Lac-St-Jean region of Quebec.

"These publications are important because they serve to provide the scientific and industrial community with an understanding of the geological set up of these high purity phosphate layers for the potential expansion of this resource to the benefit of the phosphate and lithium iron phosphate ("LFP") battery industry worldwide," says CEO John Passalacqua. "High purity Quebec igneous phosphate rock as is found in the Company's properties is believed to be able produce a large quantity of purified phosphoric acid ("PPA") to serve North America's electrification requirements."

First Phosphate believes that Quebec igneous anorthosite phosphate rock is an untapped source of high purity phosphate which can potentially be mined and transformed into large quantities of PPA to service North America's need for LFP batteries.

About First Phosphate Corp.

First Phosphate is a mineral development company fully dedicated to extracting and purifying phosphate for the production of cathode active material for the LFP battery industry. First Phosphate is committed to producing at high purity level, in responsible manner and with low anticipated carbon footprint. First Phosphate plans to vertically integrate from mine source directly into the supply chains of major North American LFP battery producers that require battery grade LFP cathode active material emanating from a consistent and secure supply source. First Phosphate holds over 1,500 sq. km of royalty-free district-scale land claims in the Saguenay-Lac-St-Jean Region of Quebec, Canada that it is actively developing. First Phosphate properties consist of rare anorthosite igneous phosphate rock that generally yields high purity phosphate material devoid of high concentrations of harmful elements.

In addition, statements in this news release that are not historical facts are forward looking statements, including, among other things, the Company's planned exploration and production activities, the properties and composition of any extracted phosphate, the Company's plans for vertical integration into North American supply chains, and statement related to the Company's ability produce a large quantity of PPA to serve North America's electrification requirements and related environmental benefits from the Company's proposed processing methods.

These statements and other forward-looking information are based on assumptions and estimates that the Company believes are appropriate and reasonable in the circumstances, including, without limitation, expectations of the Company's long term business outcomes given its short operating history; expectations regarding revenue, expenses and operations; the Company having sufficient working capital and ability to secure additional funding necessary for the exploration of the Company's property interests; expectations regarding the potential mineralization, geological merit and economic feasibility of the Company's projects; expectations regarding drill programs and the potential impacts successful drill programs could have on the life of the mine and the Company; mineral exploration and exploration program cost estimates; expectations regarding any environmental issues that may affect planned or future exploration programs and the potential impact of complying with existing and proposed environmental laws and regulations; receipt and timing of exploration and exploitation permits and other third-party approvals; government regulation of mineral exploration and development operations; expectations regarding any social or local community issues that may affect planned or future exploration and development programs; expectations surrounding global economic trends and technological advancements; and key personnel continuing their employment with the Company.
