The Southey Project is a proposed Greenfield solution potash mine located approximately 60 km north of Regina, in the Rural Municipalities of Longlaketon and Cupar. The project will be located within subsurface mineral permit areas KP377 and KP392. Potash from the Patient Lake, Belle Plaine, and Esterhazy members of the Saskatchewan Prairie Evaporite Formation will be extracted. The projected production capacity for the Southey Project is 2.8 million tonnes per year, and the life span of the project is estimated to be 65 to 100 years.
