K+S Bethune Solution Mine — Saskatchewan

Saskatchewan's only potash mine designed from inception as a pure solution mine; production since 2017. Current capacity ~2M MT/year; expanding to 4M MT/year with $3B investment over 20 years. Uses heated water injected at ~1,600m depth into the Prairie Evaporite Formation to dissolve potash; brine pumped to surface for evaporative crystallization at the surface plant. No underground workers. Subsidence risk above solution caverns must be managed. Fresh water sourced locally; brine disposal into licensed deep aquifer injection wells.
