The Vancouver-based company has been striking deals with oil players to put oilfield brine, or wastewater to good use, by extracting the lithium carbonate, which is used to make batteries for electric vehicles.

In early December MGX signed a deal with Canadian Natural Resources for water sampling and analysis at the Sturgeon Lake oilfield near Edmonton, Alberta.

Later last month it acquired 11 more metallic and industrial minerals permits in the province, covering the Redwater and Swan Hills oilfields, bringing its total brine production to nearly 500,000 barrels per day.
