ABOUT PRAIRIE LITHIUM
The Prairie Lithium project is unlocking a vast untapped lithium brine resource in the Duperow Formation in the heart of Saskatchewan’s resource-rich Williston Basin. Using emerging and innovative lithium extraction technology, the project is able to utilize existing skills and infrastructure while working within a mining-friendly jurisdiction. Lithium concentrations have been noted across the entirety of the project area, within a region that has historically been known for its oil and mining production. Exploration into the Duperow Formation on the property started in 2021, and multiple drilling & completion programs have completed to date.
The Prairie Lithium project utilizes conventional oil and gas drilling and completion methods to access lithium-rich brine from aquifers about 2.3 km underground. The Prairie Lithium project utilizes direct lithium extraction (DLE) technology to separate lithium from the brine. The extracted lithium concentrate is then converted onsite to an upgraded high-purity material. The remaining lithium-depleted brine will be disposed of back underground into a different aquifer. The DLE process uses less land and fresh water while also generating less waste in comparison to hard rock and evaporation mining.
LOCATION
The Prairie Lithium project is located in southeast Saskatchewan and is comprised of over 350,000 acres of subsurface permits.
PROJECT HIGHLIGHTS
- 5.7 MT LCE (4.0 MT LCE Indicated & 1.7 MT LCE Inferred)
- Readily accessible skills & infrastructure
- Efficient Regulatory systems built on years of local mining and oil operations
HOW LITHIUM BRINE WORKS
- A brine well is drilled
- Brine is pumped from the subsurface and sent to a lithium extraction facility
- Lithium is extracted from the brine using DLE
- The lithium free brine is disposed of back deep underground
