This is because the mining method used at Esterhazy is not grade selective. The potash mineralization is mined on one level by continuous miners following the well-defined and continuous beds of mineralization with relatively consistent grades (Section 11.2). (g) Tonnages are in U.S. Customary and metric units and are rounded to the nearest million tonnes.

Paired wells are directionally drilled, cased and cemented to the base of the potash beds and are then connected underground using proprietary potash mining techniques. Solution mining can target extraction of the potash (“ KCl ”) beds. Current mining practices allow for all three potash beds in the Prairie Evaporite formation to be recovered.
