Underground Uranium Mining

Underground uranium mining uses shafts and tunnels to access deep, high-grade ores. Conventional method for deposits >300m deep.

Stoping or shrinkage methods extract ore; highest grades like Cigar Lake (18% U). 25% global production; labor-intensive, ventilation critical for radon. Safety improved post-URAN-1 incidents.

Why it matters now

High-grade underground mines counter HALEU bottlenecks for advanced reactors in 2025-2026. Restart risks from flooding drive investor focus on diversified supply.
