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) featuring the release of Llahuin’s increased JORC Resource in July 2025. In Q2 2026, ith the Company completed an expanded diamond drilling program at the Ferro Central, Ferro South and Cerro Targets with results released in Q3 2026 including:

• 41m @ 0.42% CuEq from 18m in 24LHRD067 (incl. 143m @ 0.51% CuEq from 36m)
• 154m @ 0.66% CuEq from surface in 24LHRD065
• 156m @ 0.43% CuEq from 2m in 24LHRD055 (incl. 106m @ 0.51% CuEq from 2m)

Llahuin Copper-Gold-Moly Project

• Mineral Resource Estimate – 218Mt @ 0.38% CuEq and growing – Updated July 2025
• Llahuin is located within a very large mineralised system, noting the El Espino Copper/Gold Mine development 8km west, owned by Pucobre a large Chilean copper producer.
• Llahuin Copper-Gold Presentation – August 2026

Los Pumas Manganese Project

• Mineral Resource Estimate (Updated March 2023) – 30.2Mt @ 6.24% Mn
• Located 175 km inland from the Port of Arica and is a multiple layered tabular style manganese occurrence with a surface expression over 3.6km in length.
• Los Pumas Presentation – May 2024
• Contact us if interested in a Joint Venture opportunity at Los Pumas

🔘 Llahuin MRE ASX Release – July 2025

⚒️ UPDATED LLAHUIN 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 Ferro Central, Ferro South and Cerro Targets began Q2 2026.
• 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.”
