Southeast Saskatchewan is stepping into a new era of resource development with lithium production emerging as a major draw for industry and government alike. The region has become known for lithium brine deposits deep underground. These brines exist in favourable geological formations such as the Duperow Formation, where lithium-rich fluids lie beneath the surface along with oil and gas resources. Extraction methods now under use include direct lithium extraction technology, which removes lithium from brine and returns the depleted fluids deep underground. This process reduces environmental impact compared with older methods that relied heavily on massive evaporation ponds.

Support from provincial policies has helped unlock momentum. Investment incentive programs have been expanded to cover lithium extraction, offering fiscal benefits to projects at early stages of development. Regulatory regimes have become more streamlined, with clearer permitting pathways for resource projects. Geological surveys and exploration have identified some of the highest-grade lithium brine in Canada in southeast Saskatchewan.

Progress is already visible at the Prairie Project, developed by Arizona Lithium. That project has secured approval for its first phase of production. Lithium will be extracted using a commercial-scale direct lithium extraction unit with output initially set around 150 tonnes per year of lithium carbonate equivalent. Updated modelling based on more recent drilling has increased projected producible lithium volumes substantially.

Economic opportunity accompanies technical promise. Employment in technical, operational, and support roles is expected to expand. Revenue from royalties and resource sales may strengthen public finances. Infrastructure upgrades and related services will be needed. At the same time Saskatchewan is positioning itself within global value chains for battery materials as demand for critical minerals grows internationally.

Southeast Saskatchewan is well placed to become a leading jurisdiction for lithium production in Canada. Geological potential, supportive policy, and advancing technology work together to create strong foundations. With mindful stewardship of the environment, the region may deliver substantial benefits as one of the more promising sources of lithium for North America.
