E3 Lithium Completes Production Test on First Well to Positive Results

CALGARY, Oct. 27, 2022 - E3 Lithium Ltd. (TSXV: ETL) (FSE: OW3) (OTCQX: EEMMF), Alberta's leading lithium developer and extraction technology innovator is pleased to announce it has completed the production test on its first well in the Clearwater Project Area within the Bashaw District.

The purpose of the test is to confirm the producibility of the lithium-rich brine from E3 Lithium's (E3) resource located in the Leduc Reservoir. The production test, which included flowing 400m³/d of brine to surface for five days, has provided E3 with important data to support the commercial viability of producing lithium from the Leduc Reservoir.

The test also included reinjecting the brine back into the reservoir to confirm injectivity capacity, which is a cornerstone of E3's environmentally sustainable process. The test included re-injecting the produced brine in less than two days at a rate of 1,200m³/d.

"Testing the producibility and injectivity of the Leduc Reservoir within our Clearwater Project Area is an important and necessary step for developing our Aquifer Management Plan," said Chris Doornbos, President and CEO of E3 Lithium. "The data we've collected are key as we look to upgrade our resources from Inferred to Measured and Indicated. The Aquifer Management Plan builds out our commercial brine production design, which, combined with the upgraded resource, should enable the establishment of a Reserve in Alberta, enabling the province to become a significant lithium jurisdiction."

E3 Lithium is a development company with total of 24.3 million tonnes of lithium carbonate equivalent (LCE) inferred mineral resources1 in Alberta. 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. Through the successful scale up its DLE technology towards commercialization, E3 Lithium's goal is to produce high purity, battery grade lithium products. 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.
