- Southern Hemisphere Mining Limited (ASX:SUH) is an Australia-based minerals exploration company focused on critical minerals including copper, gold, molybdenum, and manganese primarily in Chile, South America. The company explores and develops key projects such as the flagship Llahuin Copper-Gold-Molybdenum Project, located 250 kilometers north of Santiago in the Coquimbo Region near the El Espino Copper-Gold mine, featuring a July 2025-updated JORC Mineral Resource Estimate of 218 million tonnes at 0.38% copper equivalent across three deposits with an exploration target of 260-340 million tonnes; the Los Pumas Battery Metal Manganese Project, 175 kilometers inland from the Port of Arica with a March 2023-updated Mineral Resource Estimate of 30.2 million tonnes at 6.24% manganese suitable for high-purity manganese sulphate monohydrate production for electric vehicle and battery markets; and the Lago Lithium Brine Project covering approximately 27 square kilometers in the lithium-rich Atacama region near operators SQM and Albemarle. Operations target open-pit mine-scale potential at Llahuin and high-grade oxide targets, with activities centered in Chile and headquartered at Suite 2, 20 Howard Street, Perth, Western Australia since its founding in 2005.
In recent developments, the company entered a strategic farm-in agreement with FMR Resources Limited (ASX:FMR), enabling FMR to earn up to 60% interest in four high-potential Llahuin concessions including the Curiosity-Southern Porphyry target through staged expenditures totaling A$12.5 million, with FMR completing technical due diligence and committing to deep drilling commencing in Q4 2025 following maiden drilling at Southern Porphyry in September 2025 that intersected encouraging mineralised indicators and high-grade surface oxide copper discoveries. Additional 2025 advancements include the Llahuin Mineral Resource update in July supporting mine-scale progression, quarterly activities through September featuring ongoing drilling to 1,600 meters at Target A, and the release of the annual report for the year ended June 30, 2025, alongside scheduling the Annual General Meeting for November 3, 2025 in Perth. These initiatives de-risk exploration via well-funded partnerships and advance resource delineation across copper-gold porphyry systems and battery metals.
