⚒️ Llahuin’s Resource – Increased JORC MRE released July 2025

⚒️ Llahuin’s Location – Coquimbo Region, Chile

Llahuin’s deposits are located close to the city of Illapel, in the Coquimbo Region, 250 kms north of Santiago in Chile, at an elevation of 1,300m, and 8km East of the large El Espino Copper-Gold mine development operated by Santiago listed copper producer Pucobre.

⚒️ Latest ASX Releases from Llahuin

⚒️ November 2025 – Southern Hemisphere Mining reports an update from drilling progress on the main Southern Porphyry Target at the Company’s Llahuin Copper-Gold Project in Chile – including Copper-bearing veining and strong potassic–biotite alteration observed above the main target zone.

HIGHLIGHTS

• Drilling at Target A has advanced to 1,198.9m downhole, continuing to the planned 1,600 m depth
• Copper-bearing veining and strong potassic–biotite alteration observed above the main MT target zone
• Geophysical data confirms drillhole is above MT target zone
• Ground conditions in drillhole remain excellent

⚒️ October 2025 – Southern Hemisphere Mining reports highly encouraging mineralised indicators, as Phase 1 drilling nears the Southern Porphyry’s main target within the Llahuin Copper Gold Project in Chile.

HIGHLIGHTS

• Shallow, mineralised epithermal veins intersected with up to 1.7% Copper, confirming the presence of a mineralised vein swarm within the upper Santa Maria epithermal system, providing a secondary shallow target
• In addition, highly encouraging mineralised porphyry indicators, including remobilised chalcopyrite veins and anhydrite-pyrite veins, intersected at multiple intervals downhole, above the primary target
• First drillhole 25LHDD0070 (Target A) now beyond 800m downhole depth and just above the main porphyry target

⚒️ September 2025 – Southern Hemisphere Mining reports phase I diamond drilling has commenced at the Southern Porphyry Copper Target within the Llahuin Copper-Gold-Moly Project in Chile.

HIGHLIGHTS

• ~4,000m program of directional drilling across ~3 months
• First hole at Target A is planned for 1,600m, with capacity for multiple daughter holes; ~5 weeks to complete
• Downhole geophysics to be completed on all drillholes to refine existing 3D geophysical models and identify new targets
• Assay results expected 4–6 weeks after completion of each drillhole

⚒️ August 2025 – FMR Resources to proceed with Southern Porphyry Copper-Gold JV with Southern Hemisphere Mining at Llahuin in Chile.

Southern Hemisphere Mining Chairman Mark Stowell said:

“We are delighted to welcome FMR to the Llahuin Copper-Gold Project and look forward to joint exploration success across the Southern Porphyry zone.

This strategic JV validates our long-held view of the district’s latent potential, and with drilling planned for Q4 2025. Our shareholders are well positioned to benefit from upcoming catalysts in this emerging major copper story.”

⚒️ June 2025 – Southern Hemisphere Mining Limited reports Mark Creasy’s FMR Resources will drill Llahuin’s deep Copper-Gold Curiosity-Southern Porphyry Target in Chile.

• Farm-in Partner FMR Resources led by experienced mining executive Oliver Kiddie to drill the highly prospective Curiosity-Southern Porphyry Copper-Gold Target
• FMR Resources to fund up to $13m exploration expenditure and payment of $2.67m over two stages to earn up to 60% of the JV
• Stage 1 includes a minimum of one 1,400m drill hole in the Curiosity Target scheduled for Q4 CY2025
• Southern Hemisphere retains 100% of all JORC resources at Llahuin, Resource update pending

⚒️ April 2025 – Southern Hemisphere Mining Limited reports its recently completed MT survey was also successful in defining a second large resistivity anomaly west of the Ferro deposit at its Llahuin Copper Project in establishing a sub-circular target 500m in diameter and extending to 500m deep – named the Ferro West – Copper Target.

This is in addition to the large Curiosity Copper Target announced on 15 April 2025.

⚒️ Latest Drilling Results – January 2025

The 2024 RC drill program completed a total of 2,728m drilled in 26 holes, 24LHRC044 to 069, and from depths of 53m to 168m.

Results to drill hole 24LHRC065 are reported herein, with results including:

• 105m @ 0.64% CuEq from surface to EOH, incl. 16m @ 0.85% CuEq from surface and 26m @ 0.91% CuEq from 78m – 24LHRC065
• 132m @ 0.48% CuEq from surface incl. 60m @ 0.67% CuEq from surface – 24LHRC058
• 81m @ 0.49% CuEq from 2m to EOH, incl. 48m @ 0.58% CuEq from 30m – 24LHRC055
• 120m @ 0.42% CuEq from 2m, incl. 58m @ 0.49% CuEq from 66m – 24LHRC048
• 16m @ 0.51% CuEq from 102m – 24LHRC051

These have resulted in the extension of the strike of the Cerro-Ferro system by a further 300m to 2.2km, and open potentially to the north and the south of Ferro.

These results further add to the results from the 2023 drilling campaign which included:

• 156m at 0.51% CuEq from surface in 23LHRD027, incl. 82m at 0.67% CuEq from 46m and 26m at 0.75% CuEq from 48m
• 136m at 0.47% CuEq from 42m in 23LHRD028, incl. 32m at 0.66% CuEq from 100m

Assays for the remaining drill holes to 24LHRC069 are in progress at the laboratory and results will be reported in due course.

As shown above, the drilling to date is all shallow, from surface and over a large strike of 2.2km and open. This significantly advances the open pit potential of Llahuin, and validity of testing for longer term large underground mining scope. The area between the Cerro and Ferro deposits remains open for drilling to add significant tonnes to the project.

⚒️ Llahuin Expansion Drilling Program – September through December 2024

The Company’s September-December 2024 drilling program aimed to add to the endowment of Llahuin from the current 680kt CuEq resource ahead of a JORC resource update in H2 2025.

The drilling program was designed to delineate the deeper core of the large Cerro-Ferro porphyry deposits (+2km strike) to increase tonnes at higher grades to add to the copper endowment towards establishing economic parameters for mining studies.

One key target hole is an extension of DDLLA004 which was drilled in 2013 to 644m, and lines up to the target zone north of Cerro for a lower cost extension to ~1,200m depth.

The Llahuin Project, and surrounding prospects within the company’s tenure, have numerous targets to substantially grow the resources.

Initially concentrating at shallow levels, and then expand to economic depths.
