Lake Resources N.L. provided a quarterly update on its key activities and developments. The company made significant progress on the Exploitation Environmental Impact Assessment (EIA) for its Kachi Lithium Brine Project, receiving formal observations from the Catamarca Mining Ministry, which are currently being addressed. The company expects to submit responses during the current quarter, followed by the public consultation phase as part of the overall EIA approval process, with a target EIA approval in Q3 2026. To further reduce Kachi's operating costs, Lake continues to explore alternative power solutions, including grid-based and off-grid options, engaging with power provider YPF Luz on the 'Northern Power-Line' grid-based option and evaluating other attractive grid-based and renewable energy solutions. Lake's technology partner, Lilac Solutions, announced two key advancements during the quarter: the completion of its commercial-scale ion exchange media manufacturing line in Nevada, and a binding 10-year offtake agreement with Traxys North America for lithium carbonate produced at Lilac's planned Great Salt Lake facility. Lilac also received recognition as one of the most innovative energy companies. Additionally, Lake participated in a three-day roadshow in New York organized by major financial institutions, where Argentina's President Milei and other officials presented the country as an attractive investment destination, with a focus on critical minerals and energy transition projects. Lake ended the quarter with $10.6 million in liquidity and strong capital market access, including availability under its ATM facility.

Lake Resources continues to make progress on key milestones for the Kachi Lithium Brine Project, including the Exploitation EIA approval and optimization of power solutions to further reduce operating costs. The company remains focused on advancing the project and engaging with potential off-takers and strategic partners to support its full development and construction.
