New Study Highlights High-Purity Phosphate Potential at Québec Deposit for Batteries

A peer-reviewed study published in Ore Geology Reviews examined First Phosphate Corp.’s Bégin-Lamarche igneous phosphate deposit in Québec and found geological continuity across its Mountain, North and South Zones. Researchers from Queen’s University and Université du Québec à Chicoutimi identified apatite as the primary phosphate mineral and reported concentrate grades of about 40% P₂O₅, with low chlorine and other harmful trace elements. Those characteristics could support production of purified phosphoric acid for lithium iron phosphate battery cathode materials and strengthen First Phosphate’s plans for a North American LFP supply chain. The deposit’s near-surface, thick and favorable phosphate layers may also permit open-pit mining, although further engineering, mine planning and permitting work is required.
The property’s resource estimate is supported by more than 65,000 metres of drilling, including a 40,000-metre drill campaign.
First Phosphate is targeting completion of a feasibility study by the end of 2026 or early 2027, followed by permitting and a formal investment decision by the end of 2027.
The deposit is part of the approximately 1.14-billion-year-old Lac-Saint-Jean Anorthositic Suite, described as the world’s largest anorthosite complex.
The company said the findings could guide exploration of additional igneous phosphate layers throughout Québec’s anorthosite and may have relevance to other phosphatic anorthosites globally.
