Osisko Metals Confirms High-Grade Copper-Molybdenum Results at Porphyry Mountain

Event summary

  • Osisko Metals re-assayed historical drill core from the Porphyry Mountain deposit, confirming 852 metres averaging 0.95% CuEq.
  • The Deep Porphyry Exploration Project (DPEX) will include deep drilling and re-analysis of historic drill core to outline an NI 43-101 Inferred Mineral Resource Estimate by year-end 2026.
  • Porphyry Mountain deposit remains open at depth, with historical holes stopped in mineralization between 1700 to 2100 metres.
  • Osisko aims to potentially allow future ramp access to the deeper, higher-grade DPEX Porphyry Mountain deposit as the Copper Mountain open pit reaches significant depths near the end of its mine life.

The big picture

Osisko Metals' re-evaluation of the Porphyry Mountain deposit is strategically significant as it aims to unlock deeper, higher-grade mineralization. This initiative aligns with broader industry trends of exploring and developing high-potential copper deposits to meet growing demand for critical minerals. The success of the DPEX program could position Osisko as a key player in the copper sector, particularly in eastern North America.
