Lac à Paul – Locksmith

The Lac à Paul Project

This world-class project will provide security of supply to the leading North American, European and Asian markets. The project is the most significant undeveloped phosphate deposit globally. It will add many years of mine life through the production of high-grade concentrate. Strategically located in Quebec, Lac à Paul provides excellent access to infrastructure, a tier 1 mining jurisdiction, and ability to produce a premium concentrate. The concentrate produced is easily transformed into purified phosphoric acid, a necessary ingredient for LFP batteries. Fully permitted and construction-ready, with significant improvements since 2013 FS, this project will create 1,000 jobs during operation and will contribute $12 billion in economic benefit to the region.
