Slide 9: Llahuin Copper-Gold Porphyry Growth
Llahuin Copper -Gold Porphyry Growth 9 Shallow drilling to date and working our way along strike and down this large system
Slide 10: Resource Base from Surface to Build on to Mine Scale
Resource Base from Surface to Build on to Mine Scale 10 80% Measured and Indicated, from surface, open pit style mining configuration Exploration Target an additional 260Mt to 340Mt
Slide 11: A Large and Growing Resource Underpinning Value
A Large and Growing Resource Underpinning Value 11 Measured Indicated and Inferred Resources as at 30 July 2025 Exploration Target an additional 260Mt to 340Mt ore
Slide 12: Llahuin Central Deposit - Resource Block Model
Llahuin Central Deposit – Resource Block Model 101mt @ 0.41% CuEq ~90% Measured, 10% indicated Ore from surface Low strip ratio ~1:1 Defined depth of open pit ~400m 12 vertical Higher grade core Best drill result-DDLLA021 incl 336m@ 1.1%CuEq
Slide 13: Llahuin - JORC compliant resource from surface - what have you missed?
Llahuin –JORC compliant resource - from surface –OK, what have you missed? Significant Mineralised System ~3.5km strike Up to 1km wide with multiple centers (and feeder zones?) Lightly drilled and mostly shallow -to ~150m So, what generated all of this is the key Major Resource Growth Area Ferro -Ce
Slide 14: Llahuin Plan View
Llahuin Plan View Significant System ~3.5km strike Resource Growth Area Ferro -Cerro strike and depth Feeder zone(s) yet to be intersected with 14 drilling Undrilled large targets incl east of creek and Southern Porphyry
Slide 15: Unlocking the scale potential of the Llahuin Copper system
Unlocking the scale potential of the Llahuin Copper system • Strong chalcopyrite mineralisation in drillhole 24LHRD067 • Very similar to the mineralisation at Central Porphyry 15 * Cautionary Statement: Visual estimates of mineral abundance should never be considered a proxy or substitute for labora
Slide 16: Llahuin Copper-Gold: Deeper drilling confirming growth potential
Llahuin Copper -Gold: Deeper drilling confirming growth potential 16 Cerro 24LHRD055 incl 106m @ 0.51% CuEq Cerro 24LHRD065 154m @ 0.65% CuEq fr 0m
Slide 17: Cerro-Ferro
Cerro-Ferro modelling is working as it is identifying targets where we have JORC resources Studies in progress to improve the deeper copper core targets for drilling *, SOUTHERN | 2 +) HEMISPHERE mining limited
Slide 18: VectOres Isotope Analysis - Feeder Zone Vector
VectOres Isotope Analysis- Feeder Zone Vector The problem: Multiple intersections drilled over 5 years and 2+km strike and how do all of the systems relate and where is the source of 18 mineralisation?
Slide 19: Value Add of VectOres Isotope Analysis
Value Add of VectOres Isotope Analysis • Contoured data in cross section view defines paleohydrothermal system flow paths • Three distinct mineralisation systems identified at Llahuin with isotopically lighter cores that grade out to higher copper isotope values
Slide 20: VectOres Analysis - Ferro Feeder Zone Vector
VectOres Analysis-Ferro Feeder Zone Vector 20 Shape of system Proposed drill trace in black
Slide 21: VectOres Analysis - Cerro North Feeder Zone Vector
VectOres Analysis-Cerro North Feeder Zone Vector The Cerro North section shown with the drill core position extension suggested with the black arrow. The lowest copper isotope values are found in this section thus the center of system is predicted near the pink outline. Extension of hole DDLLA028 by
