Lithium South owns 100 per cent of the HMN lithium project located in Salta and Catamarca provinces, Argentina, in the heart of the Lithium Triangle. The Salar del Hombre Muerto has a history of lithium production, with Rio Tinto Lithium (formerly Arcadium Lithium and recently purchased by Rio Tinto Corp. for $6.7-billion (U.S.) in March, 2025) in operation to the south of the HMN Li project for over 25 years. The HMN Li project is adjacent to the east with a U.S.-billion-dollar lithium development by Posco Argentina, now in lithium production. Exploration work to date has delineated a National Instrument 43-101-compliant, 1,583,200-tonne lithium carbonate equivalent (LCE) resource at an average grade of 736 milligrams per litre lithium, with 1,463,000 tonnes in the measured category and 120,000 tonnes in the indicated category, at a cut-off grade of 500 mg/L Li, on the Alba Sabrina, Natalia Maria and Tramo claim blocks, three of five non-contiguous blocks that make up the HMN Li project. A recent preliminary economic assessment, dated April 30, 2024, delineates potential to develop a 15,600-tonne-per-year lithium carbonate project. Lithium South Development is now moving the project forward to a feasibility study. We seek Safe Harbor.
