E3 LITHIUM LTD. announced the discovery of higher lithium concentrations in the Nisku Aquifer (the Nisku) through a new six well sampling program conducted late in 2023. E3 Lithium sampled brine in the Nisku from six well locations in its Clearwater Project Area that outlined lithium concentrations as high as 87 mg/L. These results are from the first Nisku samples in the Clearwater Project area, and are higher than the historic Nisku samples, which outlined lithium grades up to 75 mg/L. E3 Lithium is investigating potential causes further and may resample. The Nisku is located above the Leduc Aquifer and stretches across E3 Lithium's entire permit area where the Company holds mineral rights, which include the rights to the lithium within the Nisku.

The Nisku and Leduc are Devonian stacked reef complexes that have similar geological properties, however, the Nisku is generally not as thick as the Leduc. As outlined in E3's Preliminary Economic Assessment, the Clearwater Lithium Project has an NPV8% of USD 1.1 Billion with a 32% IRR pre-tax and USD 820 Million with a 27% IRR after-tax1. E3 Lithium's goal is to produce high purity, battery grade lithium products to power the growing electrical revolution.

With a significant lithium resource and innovative technology solutions, E3 Lithium has the potential to deliver lithium to market from one of the best jurisdictions in the world.

All of E3 Lithium samples were analyzed by a third-party certified laboratory, following independently verified sample acquisition procedures that maintained a strict chain of custody, in accordance with The Canadian Institute of Mining, Metallurgy and Petroleum (CIM) guidelines.
