Lake Resources N.L. (ASX: LKE, OTC: LLKKF) provided a quarterly update on its activities. The company continued to advance the approval of the Exploitation Environmental Impact Assessment (Exploitation EIA) for its Kachi Lithium Brine Project from the Catamarca Ministries of Environment and Mining. During the quarter, the Ramsar site zonification was received, marking another key milestone as Lake continues to move towards delivering Kachi as a 'shovel-ready' project. The company also prioritized developing an attractive power solution to further de-risk and reduce Kachi's operating costs, advancing Kachi's position as a tier-one asset with first quartile operating costs. Lilac Solutions, Kachi's 20% owner and technology partner, released its fifth-generation ion exchange technology (Gen 5 Lilac IX), which is expected to have a positive direct impact on Kachi's capital and operating costs. Lake also welcomed the Hon. Alexander Downer AC to Lilac's Oakland facility to review Lilac's advancements in direct lithium extraction (DLE) technology. The company materially reduced its calendar year 2025 cash outgoings by approximately 45% compared to calendar year 2024 and ended the quarter with strong liquidity of $15.3 million.

Lake Resources will continue to evaluate and execute on opportunities to further right-size the business in calendar year 2026.
