Southern Hemisphere Mining Limited is an ASX-listed, successful critical minerals explorer in Chile with Copper, Gold, Moly and Manganese assets.

Its flagship asset is the Llahuin Copper-Gold-Moly Project (north of Santiago) with the Company drilling at the huge company maker deep Copper-Gold target beginning in September 2025 – following the release of its increased JORC Resource in July 2025.

🔘 New ASX Release – February 2026

⚒️ UPDATED MRE HIGHLIGHTS

• Mineral Resource Estimate (MRE) for the Llahuin Copper-Gold Project of 218Mt at an average grade of 0.38% CuEq
• MRE is across three deposits, with strong potential to define further resources (refer to new Exploration Target)
• Progressing towards mine scale open pit configuration
• Drilling at the Southern Porphyry Target began in September 2025.

⚒️ Southern Hemisphere’s Chairman Mr Mark Stowell commented:

“We are delighted to report this Mineral Resource update which is a compliment to our team’s work over the past 4 years at Llahuin.

The JORC Resource underpins the future potential of this project over a substantial strike of ~4km with our shallow drilling adding to the from- surface resources and prospects. This does two things, first: to continue advancing towards mine scale and secondly: the potential of this system that can produce large tonnages at surface over such strike length has a high probability of substantial copper endowment at higher grades deeper. We will initially test this at the Curiosity-Southern Porphyry scheduled for drilling in Q4 2025 with FMR Resources Limited (ASX: FMR).

We see considerable scope for resource growth at Cerro-Ferro including the Ferro West MT target, and the recent discovery at Ferro South given shallow drilling to date in these areas. Our Exploration Target is ~260-340Mt in addition to the 218Mt JORC Resource.”
