Opus One preparing for winter drilling at Noyell

Executive Summary

• Opus One Gold reports a successful 2025 winter drilling program (≈9,000 m) on its 100% owned Noyell Gold Project, revealing that Zone 1 mineralization is open in multiple directions and at depth.
• New geological interpretation suggests Zone 1 represents sulphidisation of a BIF within a tension zone along the CBDC deformation corridor, with gold grades correlating to sulphide content.
• The company is preparing for an expanded 2026 drilling campaign (three rigs secured) targeting infill, extension of Zone 1 and historic high‑grade zones in the western portion of the property.

Key Details

• Drilling Summary (2025 Winter): ~9,000 m total; core recovered as NQ size; all assays completed and previously released.
• Zone 1 Geometry:
• Strikes N 110°, dips 66° S.
• Extends ≈600 m E‑W at the 300 m level; reaches surface under overburden.
• True thickness up to 15 m in upper portion (hole NO‑25‑07); deepest high‑grade interval >5 m thick (hole NO‑25‑13).
• Mineralogy & Alteration: Stockwork of quartz, iron carbonates and semi‑massive sulphides (mainly pyrrhotite) hosted in fine sediments of the Taibi Formation; alteration halo of chamosite, sericite, iron carbonates. Highest gold grades coincide with highest sulphide content; visible gold observed in quartz.
• Open‑Pit Potential:
• Eastward open at surface (DDH NO‑25‑18).
• Depth open along steeply dipping high‑grade shoot east (DDH NO‑25‑13).
• Central zone open at depth on lower‑grade shoot (NO‑25‑15a).
• Westward vectors open at depth (holes NO‑25‑15a, NO‑25‑17, historic Soquem 1311‑97‑24).
• Current Work: Digitization and spectrometric analysis of core to pinpoint gold occurrence and mineralogical associations; data from 2025 biochemical survey being compiled.
• Future Drilling (Early 2026):
• Permitting underway.
• Three drill rigs secured for winter 2026.
• Targets include infill/extension of Zone 1 in all directions and new western targets where historic drilling reported significant gold (1980s‑1990s).
• QA/QC Program: One control sample inserted after every nine regular samples; includes certified blanks and graded material; fire assay (50 g) with ICP‑OES finish; ore‑grade gravimetric finish for ≥10 g/t Au.

Notable Quotes

“The 2025 drilling program on its Noyell project has been a real success… The gold mineralization of Zone 1 has significantly increased and remains potentially open in many directions… We are very optimistic about the forthcoming drilling program… definition drilling of Zone 1 should accelerate significantly.” – Louis Morin, CEO, Opus One Gold Corp.
