Saguenay, Quebec–(Newsfile Corp. – September 21, 2026) – First Phosphate Corp. (NASDAQ: PHOS) (CSE: PHOS) (OTCQX: FRSPF) (FSE: KD0) (“First Phosphate” or the “Company“) is pleased to announce that the Company’s Bégin-Lamarche Igneous Phosphate Deposit has been subject of a peer-reviewed study in Ore Geology Reviews (published on ScienceDirect), a premier scientific journal focusing on ore genesis and exploration.
The study highlights how economic, phosphate-rich layers in the Bégin-Lamarche deposit were formed. Results indicate these layers are low in chlorine and other trace elements making them suitable as a potential high-purity source of phosphate for production of purified phosphoric acid (“PPA”), a critical precursor in the manufacture of lithium iron phosphate (“LFP”) battery cathode active material.

The research, authored by scientists from Queen’s University and Université du Québec à Chicoutimi (UQAC), focuses on the geological characterization of the Mountain, North and South Zones of the Company’s Bégin-Lamarche igneous phosphate deposit, part of the 1.14 Ga Lac-Saint-Jean Anorthositic (“LSJA”) Suite – the largest anorthosite complex in the world.
Through detailed mineralogical, petrological and geochemical analysis, the study further reinforces the strategic importance of Québec igneous phosphate as a secure North American feedstock source capable of supporting First Phosphate’s vertical integration strategy along the LFP battery supply chain.
The conclusions of the study are summarized below:
- The Bégin-Lamarche deposit is hosted in massif anorthosite and associated nelsonite and oxide-apatite-mafic to ultramafic rocks of the Lac-Saint-Jean Anorthositic Suite. Apatite represents the primary phosphatic mineralization confirming the magmatic origin and geological continuity of the phosphate-bearing zones across the Mountain, North and South Zones.
- Analytical results demonstrate that the phosphate mineralization is capable of producing a high-grade phosphate concentrate. Testing indicates concentrate levels around ~40% P₂O₅, which aligns above global averages for igneous phosphate concentrates and supports suitability for PPA production.
- Geochemical characterization demonstrates low levels of deleterious trace elements unlike those which are commonly associated with sedimentary phosphate deposits. Such low concentrations of deleterious trace elements enhance the potential for producing high-purity PPA suitable for LFP cathode active material applications.
- The geometry, thickness and near-surface occurrence of certain phosphate layers suggest favorable conditions for potential open-pit mining scenarios, subject to further engineering and mine planning studies, thereby supporting the long-term development potential of the deposit.
These findings provide the foundation for the exploration of other igneous phosphate layers throughout the Québec anorthosite that are suitable for LFP battery production. Results may apply to other phosphatic anorthosites globally offering new insights for high-purity phosphate resource development.
