Arizona Lithium Ltd. (AZL) on July 15 said it discovered a new lithium formation at the site of its Prairie Lithium project in Saskatchewan, Canada’s Williston Basin.
The discovery was made by an exploration well drilling in the Souris River Formation, which sits directly beneath the Duperow Formation. Samples of brine from the Souris River indicate a lithium concentration of 86 milligrams of lithium per liter (mg/L), the company said in a news release.
The exploration well was converted to a Duperow production well and was pumped at a stable rate of 500m3 per day. It produced about 2,400 m3 of brine before it was shut in for a build-up test to monitor reservoir pressure response, Arizona Lithium said.
