Indigo Exploration Inc. announced it has doubled its land position in central Alberta, Canada covering significant subsurface Devonian reef reservoir aquifers with the potential to produce large volumes of lithium-bearing formation brine. The Company's permits recently granted by Alberta Department of Energy now total 147,904 hectares (147.9 km or 365,479 acres) in three key areas of higher lithium brines and adjacent to permits held by E3 Lithium Ltd., LithiumBank Resources Corp., and Highwood Asset Management. The acquired permits are in proximity to wells recording lithium brine levels between 72 and 130mg/l from the Leduc Carbonate Reef complex Woodbend Group and the underlying Beaverhill Lake Group rock.

The aquifers in these units historically have been known to host the highest grades of lithium-in-brine in Alberta. The recent Indigo permits increase its land positions in the Fox Creek and Leduc-Legal areas. There are over 700 wells that have been drilling on the Indigo permit areas.

These 700 wells of various status, from producing to abandoned, penetrate the Mississippian or Devonian Formations across the Indigo permits. This well dataset is being evaluated to select the most suitable wells to conduct a comprehensive sampling program planned to start in the first quarter of 2023.
