Slide 1: Trek South Investor Presentation
Trek South Investor Presentation Unfolding a Major New Porphyry Copper-Gold Discovery in BC’s Golden Triangle Visible Copper Minerals and Broad Intercepts of Porphyry-Style Alteration. Assays Pending Underlying Source Intrusion Zeroed-in and Primed for Drilling Planning for 2027 Phase 2 Drilling Und
Slide 2: Opportunity
Opportunity An unfolding porphyry copper-gold discovery at Trek South First-ever, Phase 1 drill program just completed (Sept 2026) Visible copper minerals and broad intercepts of porphyry-style alteration. Assays pending Phase 1 drilling put us directly over what we believe to be the core (i
Slide 3: This is What We've Been Hunting: A Porphyry
This is What We’ve Been Hunting: A Porphyry • BC alkalic-style • broader on surface • narrower at depth • deep rooted ~1500 metres • somewhat carrot-shaped • highest grades in the root zone ORETERRA METALS 3
Slide 4: We've found it. Though we're not yet in the high-grade root
We’ve found it. Though we’re not yet in the high-grade root, drill results suggest we are above it ORETERRA METALS 4
Slide 5: This is Where We Drilled
This is Where We Drilled • 4,600 metres of drilling were completed in 13 holes. Assays for this work are pending • Phase 1 drilling was focused along the ‘A Zone’ porphyry-style alteration pathway targeting into underlying IP and magnetic anomalies – see additional photos in Appendix A’ • Drilling s

Slide 8: Results of Maiden Drill Program
Results of Maiden Drill Program August-September This Year • All holes cut multi-hundred metre intercepts of porphyry-style alteration, but the central holes in the fence, TS26-06, TS26- 09 and TS26-10 (Trek South “A” Zone - slide 9, below) were (visually) best • Assays are pending ORETERRA METALS 8

Slide 10: Results of Maiden Drill Program
Results of Maiden Drill Program August-September This Year • The central holes (TS26-06, 09, 10) combined intense, pervasive porphyry-style alteration with visibly encouraging observations of copper minerals, including one or several of bornite ± chalcopyrite ± chalcocite ± malachite ± chrysocolla (
Slide 11: Example of mineralization seen in recent drilling: bornite
Example of mineralization seen in recent drilling: bornite (63.3% copper by weight) and chalcocite (79.9% copper by weight) at 178.5 m in hole TS26-10. Assays pending ORETERRA METALS 11
Slide 12: Example of intense green porphyry-style epidote alteration
Example of intense green porphyry-style epidote alteration with disseminated bornite and chalcopyrite at 343 metres in hole TS26-10. Assays pending ORETERRA METALS 12
Slide 13: Drilling to Date Suggests the Intrusive Root is Below Holes TS26-06, 09, 10
Drilling to Date Suggests the Intrusive Root to the System is Below the Location of Holes TS26-06, 09, 10 • Modeling of the magnetic data also points to its location (next slides) ORETERRA METALS 13
