Significant Progress with 40MW Energy Infrastructure Project

• Detailed engineering works completed on 40MW Medium Voltage Line Project
• Competitive tender process underway for electric transmission line and transformer station
• Grid connection access to improve operational reliability and renewable energy integration

Argosy Minerals Limited (ASX: AGY) has announced significant progress on the energy infrastructure development for its 12,000tpa Rincon Lithium Project in Salta Province, Argentina. The Salta Electricity Distribution Company S.A. (EDESA) has completed detailed engineering and feasibility works on a 40MW Medium Voltage Line (MVL) Project to provide a reliable 33kV power connection to the Rincon Project from the Argentina National Power Grid. The ~8.6km transmission line will connect via a local sub-station to the Rincon Project site. This access to reliable, grid-based power is expected to reduce operational costs, strengthen project economics, and minimize the need for on-site diesel power generation. The next phase involves a competitive tender process for the electric transmission line and associated transformer station construction works. In parallel, the company is engaging with local renewable energy providers to establish Power Purchase Agreements (PPAs) to ensure sustainable and cost-efficient energy supply. Securing access to national grid power represents a critical milestone for the Rincon 12,000tpa project development, materially de-risking and progressing the feasibility works while improving operational reliability, project economic viability, and environmental performance.

The energy infrastructure program is being conducted in alignment with the neighboring Rio Tinto Rincon Project, where similar works are being arranged for Rio Tinto to access energy via the same EDESA infrastructure program. Ultimately, it is envisaged that both companies will build electric transmission lines in parallel to connect to the Altiplano sub-station site and onto the National Power Grid.
