Lithium in saline brines (Duperow Aquifer) in southeast Saskatchewan and the importance of subsurface geology and hydrogeology.
There is currently an enormous exploration interest in brine-hosted lithium from the Duperow/Leduc Aquifer in Western Canada. Yet, the distribution of lithium in subsurface brines has received little attention in the open literature. The key question remains: what controls the distribution of lithium in subsurface brines?
Understanding the paleohydrogeology and hydrochemistry of saline brines in the Williston Basin is the starting point for understanding the distribution of lithium in the subsurface. This requires mapping of the subsurface geology, hydrogeology, and hydrochemistry, supplemented by brine sampling and analysis. Results reveal that not all saline brines host elevated lithium concentrations and that there is something special about the Duperow Aquifer in southeast Saskatchewan.
This presentation will review the relevant regional hydrogeology and hydrochemistry of the Duperow Aquifer in Saskatchewan, then present some recent drilling and testing results that support a newly-developed exploration model of a widespread layered distribution of lithium in the Duperow Aquifer.
