SOP Project Overview

Saskatchewan Mining and Minerals has been producing sodium sulphate in Chaplin, Saskatchewan, for over 75 years and distributing this product across Canada and the United States. Thanks to our focus on innovation, efficiency, and environmental stewardship, Saskatchewan Mining and Minerals is transforming our Chaplin facility to produce sulphate of potash (SOP), while continuing to manufacture sodium sulphate using our Glauber’s salt reserves as a primary input. Construction of the transformation project started in the summer of 2025 with the expansion of our storage and loadout facilities, and production of sulphate of potash is expected to begin in 2027.

Saskatchewan Mining and Minerals will be chemically producing sulphate of potash using cutting-edge technology, the first of its kind in Canada. Although the chemical process of Glaserite has been around for decades, the approach our design utilizes enhances the efficiency of the process, both in terms of a more complete utilization of inputs, and substantial energy savings in the process. We expect to achieve a 10% increase in input efficiency and up to a 25% reduction in Greenhouse Gas Emissions in comparison to current Glaserite processes.
