07/22/2025 – 03:15 AM

CALGARY, Alberta – E3 Lithium (TSXV: ETL), a key player in the Canadian lithium landscape, has officially filed its NI 43-101 technical report for the Garrington District project. This move underscores the company’s commitment to transparency and rigorous evaluation of its assets in central Alberta.

The report, titled “NI 43-101 Technical Report for the Garrington District Lithium Resource Estimate,” is dated July 18, 2025, with an effective date of June 25, 2025. It largely echoes findings previously aired in a June 25th press release: “E3 Lithium Outlines an Inaugural Measured and Indicated Mineral Resource Estimate of 5.0 Mt LCE for the Garrington District,” according to the company.

Crucially, the Garrington Report presents no significant deviations from the data shared in that initial June release. Investors seeking a deeper dive can access the report on E3 Lithium’s corporate website (www.e3lithium.ca/technical-reports/) and via SEDAR+ (www.sedarplus.ca). This accessibility reinforces the company’s dedication to keeping investors informed.

The NI 43-101 report, a cornerstone of mineral project disclosure, was meticulously reviewed and greenlit by Meghan Klein, P.Eng., and Alexey Romanov, PhD., P.Geo., both recognized as “Qualified Persons” under NI 43-101 standards, lending credibility to E3 Lithium’s resource estimates.

Equity Awards Grant

Beyond the resource update, E3 Lithium also disclosed the granting of 40,000 incentive stock options to Rob Knowles, VP Investor Relations. This aligns to the compensation plan stated on March 7, 2025. The options, exercisable at $0.81 per share for three years, vest over the next two anniversaries reflecting a strategy to incentivize talent.

Chris Doornbos, President & CEO issued a statement on behalf of the Board of Directors.
