• Continued advancement of Kachi Lithium Brine Project's Exploitation Environmental Impact Assessment
• Ramsar site zonification received, marking key milestone
• Prioritized developing attractive power solution to further de-risk and reduce Kachi's operating costs
• Lilac Solutions released fifth-generation ion exchange technology, expected to benefit Kachi

Lake Resources ('Lake' or the 'Company') continued to advance the approval of the Exploitation Environmental Impact Assessment ('Exploitation EIA') for its Kachi Lithium Brine Project ('Kachi') 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. Argentina's October 2025 election outcome was a strong endorsement of President Milei's reform agenda and provided momentum for continued foreign direct investment in Argentina. Lake 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. During the quarter, Lilac Solutions ('Lilac'), Kachi's 20% owner and technology partner released its fifth-generation ion exchange technology ('Gen 5 Lilac IX') and white paper; Gen 5 Lilac IX is expected to have a positive direct impact on Kachi's capital and operating costs. Lilac and Lake welcomed the Hon. Alexander Downer AC to Lilac's Oakland facility to review Lilac's advancements in direct lithium extraction ('DLE') technology; Lake's partnership with Lilac positions Kachi to be an environmental leader in lithium extraction. Lake materially reduced calendar year 2025 cash outgoings by ~45% as compared to calendar year 2024 and will continue to evaluate and execute on opportunities to further right-size the business in calendar year 2026. Lake ended the quarter with strong liquidity of $15.3 million including the benefit of ~$2.5 million received during the quarter associated with the August 2025 capital raise.
