We mine rock salt using a drill-and-blast mining technique in deep salt deposits. We start by cutting into the rock salt face using specialized equipment. We then drill holes into the face and use explosives to break the salt into small pieces. Diesel-powered front-end loaders and trucks load and haul the salt to a crusher where it is reduced in size, loaded onto a conveyor belt and transported to a mill. At the mill the salt is crushed further and screened to the required sizes before being hoisted to the surface.
Our rock salt mines are located underground, as deep as 1,800 feet below the surface. We extract salt from each mine in rectangular "room" sections, leaving behind vast “pillars” of salt to support the mine structure.
