First Phosphate Reports High-Grade Assay Results from Quebec Drill Program

First Phosphate Corp has released the latest assay results from its ongoing 25,000-meter drill program at the Begin-Lamarche project in Quebec, revealing several high-grade intersections that demonstrate the robust mineralization potential of the project. The results include particularly strong showings in the Phosphate Mountain Zone, where drill hole BL-24-56 intersected 11.82% P2O5 over 92.5 meters from a surface depth of 6.5 meters. This zone features a thick layer of phosphate-bearing nelsonite outcropping on the surface, with multiple other high-grade intersections exceeding 10% P2O5, indicating substantial near-surface mineralization that could support efficient mining operations.

The Phosphate Mountain Zone is now merging with the Northern Zone, creating a significant mineralized system with a 500-meter-thick phosphate envelope containing up to five individual layers ranging from 60 to 100 meters in thickness. The combined strike length of these two zones extends approximately 600 meters, suggesting a substantial resource base. In the Northern Zone specifically, drill hole BL-24-40 intersected 7.76% P2O5 over 88.2 meters from a depth of 186.0 meters, including a higher-grade section of 9.33% P2O5 over 61.2 meters, demonstrating consistent mineralization at depth.

Additional positive results from the Northwestern Zone and Southern Zone indicate the project's mineralization potential extends across multiple areas, supporting the prospect of a comprehensive mining operation. With 23,398 meters drilled to date and assays completed for 9,155 meters, the program has generated substantial data while 4,691 samples remain pending at the laboratory. These results strengthen First Phosphate's position in the emerging battery materials sector, as high-purity phosphate is essential for lithium iron phosphate (LFP) batteries used in electric vehicles and energy storage systems. The company's progress at Begin-Lamarche comes at a critical time when North American battery supply chains are seeking domestic sources of critical minerals to reduce reliance on foreign suppliers, particularly from China which currently dominates phosphate production.

The project's significance extends beyond the battery industry to agriculture, where phosphate remains a crucial component of fertilizers. The combination of high-grade mineralization, substantial thickness, and near-surface occurrence positions the Begin-Lamarche project as a potential strategic asset for both the clean energy transition and food security. As global demand for both battery materials and agricultural inputs continues to grow, First Phosphate's Quebec project represents an important development in establishing North American supply chains for these essential commodities.
