Lithium Brine Properties Joint Venture
The lithium brine properties consist of 21 permits totaling 119,739 acres (48,457 hectares) of Subsurface Crown Mineral Dispositions in the Williston basin of Southern Saskatchewan. Two independent laboratories(Isobrine Solutions (Edmonton, AB) and AGAT Laboratories (Calgary, AB) were engaged to analyze multiple zones of interest and measure lithium concentrations present in the formation brine. Within these zones, the targeted intervals returned lithium concentrations up to 96.3 mg/l.
