Slide 6: Restructured With Success at Trek South in Mind
Restructured With Success at Trek South in Mind CEO Keough took on the challenging task of restructuring the former Romios (now Oreterra) in June 2025 for one reason: The Company’s newly drill-ready Trek South porphyry copper-gold prospect shows very high potential to deliver a major discovery (se
Slide 7: Why Is Trek South So Exceptional As a Porphyry Copper-Gold Prospect?
Why Is Trek South So Exceptional As a Porphyry Copper-Gold Prospect? Because It Has Everything We Look For: 1. A strategic location adjacent to the Teck – Newmont JV and very close to their 10.
