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 Phosphate Mountain Zone delivered particularly impressive results, with drill hole BL-24-56 intersecting 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 geological significance extends beyond individual drill holes as the Phosphate Mountain Zone is merging with the Northern Zone, creating a substantial mineralized system. The Northern Zone has delineated a 500-meter-thick phosphate mineralized envelope containing up to five individual layers ranging from 60 to 100 meters in thickness. The combined strike length of the Phosphate Mountain Zone and Northern Zone now extends approximately 600 meters, suggesting a continuous mineralized system of considerable scale. 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.

Additional positive results from the Northwestern Zone and Southern Zone indicate the project's mineralization potential extends across multiple areas, supporting the concept of a district-scale phosphate resource. With 23,398 meters drilled to date from the planned 25,000-meter program, assays from 9,155 meters have been completed while 4,691 samples remain pending at the laboratory. These results strengthen First Phosphate's position in the emerging battery materials supply chain, particularly as demand for lithium iron phosphate (LFP) batteries continues to grow in the electric vehicle sector. The company's focus on developing battery-grade phosphate material aligns with global efforts to secure domestic supply chains for critical minerals essential to the clean energy transition.

The Begin-Lamarche project's potential to become a significant source of high-quality phosphate material carries implications for both the battery and agriculture industries, which rely heavily on phosphate resources. As the world transitions toward electrified transportation and sustainable agriculture practices, secure supplies of high-purity phosphate become increasingly valuable. These latest drill results not only demonstrate the technical viability of the project but also highlight Quebec's emerging role as a strategic jurisdiction for critical mineral development, supporting regional economic growth while contributing to North America's energy security objectives.
