LAKE RESOURCES ANNOUNCES THE SUBMISSION OF ITS PRODUCTION ENVIRONMENTAL IMPACT ASSESSMENT FOR PHASE ONE OF THE KACHI PROJECT

  • Submission of the Production EIA to Catamarca Mining Authority marks an important milestone for Kachi and represents the culmination of extensive field work and community engagement completed over the past three years.

  • The development plan for Kachi is designed to minimize the consumption of fresh water and maintains the hydrogeologic system as close to baseline conditions as possible.

  • The innovative Project development plan consumes less than 2.5 percent of the average annual natural groundwater replenishment to the basin (i.e., recharge), highlighting Kachi's exceptionally small water footprint.

  • The Project will provide significant economic and social benefits to Catamarca Province.

SYDNEY, March 26, 2024 /PRNewswire/ -- Clean lithium developer Lake Resources N.L. (ASX: LKE; OTC: LLKKF) ("Lake" or "the Company"), is pleased to report the submission of the Production Environmental Impact Assessment (the "Production EIA" or "EIA") for its flagship Kachi Project ("Kachi" or "the Project") to the Catamarca Ministry of Mining in Catamarca Province, Argentina. Lake's innovative and sustainable Project development plan will result in a small water footprint, amongst the lowest for lithium brine projects per tonne.

The Production EIA, which was submitted in accordance with Lake's operational timeline, is a statutory requirement under the Argentina mining and environmental regimes and is intended to demonstrate that due attention has been given to the potential impact of the mining operations on the environment and local community.

The EIA was prepared by Knight Piésold A.C.S.A., a global engineering consulting firm, in accordance with the General Environmental Law No. 25,675, the National Law No. 24,585 on Environmental Protection for Mining Activity in Argentina, (Annex III), the Mining Code of the Nation (Title 13, Section 2), the SAA Provision No. 74/2010 and the M.M. Resolution No. 1014/2023.

The EIA is based on the production scenario presented in the Definitive Feasibility Study[1] in which lithium brine is extracted via production wells, pumped to the Direct Lithium Extraction ("DLE") plant for lithium recovery and then injected back into the subsurface via injection wells. The Lilac ion exchange process requires a fraction of the water required for evaporation ponds and absorption DLE technology.

Lake has also incorporated a Zero Liquid Discharge unit that further reduces freshwater consumption by about 75%[1]. The injection of spent brine allows Lake to design a system that maximizes lithium recovery while maintaining the hydrological/hydrogeological system as close to baseline conditions as possible during operations. Other significant environmental benefits of Kachi include a smaller land footprint and lower solid waste output compared to traditional evaporation ponds and hard rock projects.
