• Catamarca Government approves Ramsar Environmental Management Plan
• Represents critical step towards final Exploitation EIA approval in 2026
• Kachi project design aligns with Argentina's pro-mining reforms and anticipated US-Argentina trade framework

Lake Resources N.L. (ASX: LKE; OTC: LLKKF) today welcomed the approval by the Government of Catamarca that it has completed the Management Plan and Strategic Environmental Assessment ('Management Plan') for the Ramsar North Subsite 'Lagunas Altoandinas y Puneñas'. The Kachi lithium brine project ('Kachi') in Catamarca Province, Argentina is a part of the Ramsar North Subsite. This approval is a critical step forward for receipt of the final Exploitation Environmental Impact Assessment ('EIA') approvals expected in 2026. The Ramsar Convention is an international treaty for conservation and sustainable use of wetlands. The Catamarca Ministry of Water, Energy and Environment is responsible for implementing Ramsar obligations, administering the Management Plan, and ensuring that all activities within the site comply with the Convention's environmental safeguards. The completion of the Management Plan represents an important institutional milestone for the Catamarca Province, strengthening the regulatory framework and establishing a structured basis for biodiversity protection, environmental monitoring, and sustainable development in the high Andean wetlands. Kachi's design, leveraging Lilac Solutions' Gen 5 ion-exchange technology, eliminates evaporation ponds, slashes freshwater use by over 90%, and ensures zero discharge to sensitive ecosystems, aligning with Argentina's pro-mining reforms and the anticipated US-Argentina trade framework for secure critical minerals supply chains.

Lake remains focused on advancing the EIA approval process, securing strategic partnerships to fund Kachi Phase One construction and progressing to a final investment decision.
