From Prairie Surface
to Mineral Seam

Each scroll carries you deeper. Three operational layers, one continuous supply chain — from drill rig to rail car in under 72 hours.

0mSURFACE — AERIAL OVERVIEW

Infrastructure at Continental Scale

Four shaft complexes across 180,000 hectares of mineral tenure. Rail loadout capable of 140 covered hopper cars per shift. The operation visible from orbit.

The Hoist Tower at Dawn

Twin Blair multi-rope hoists move 40-tonne skips every 90 seconds. The headframe stands 76 metres above the surface — a landmark visible 30 kilometres across the plain.

Cathedral Rooms Carved in Salt

Continuous miners advance on 14-metre centres, carving rooms 9 metres wide through the Patience Lake member. Conveyor haulage to ore passes runs 24/7 across 340 lane-kilometres of developed roadway.

Why This Matters · Food Security Data

The Mineral Beneath
feeds the world above

Potassium chloride is not a commodity. It is the nutrient that determines whether a harvest feeds a family or fails one. These numbers are why the depth matters.
