First Phosphate reports peer-reviewed study backs high-purity phosphate potential at Bégin-Lamarche deposit in Québec

• First Phosphate flagged a peer-reviewed study on its Bégin-Lamarche igneous phosphate deposit, outlining formation of economic, phosphate-rich layers.
• Test work cited phosphate concentrate grades near 40% P₂O₅, supporting potential production of purified phosphoric acid for LFP batteries.
• Geochemical results showed low chlorine and low deleterious trace elements versus typical sedimentary deposits, improving prospects for high-purity output.
• Near-surface geometry and thickness of some layers pointed to potential open-pit mining scenarios, pending further engineering and mine planning.
