Opus One talks LIBS gold results

Executive Summary

• Opus One Gold Corp. reported positive results from a Laser Induced Breakdown Spectrometry (LIBS) study conducted by ECORE on drill core from its Noyell gold project in Quebec.
• The study analyzed mineralized core from holes NO-25-07 and NO-25-13, revealing a strong correlation between precious metals (gold and silver) and sulphide minerals, particularly pyrrhotite.
• Key findings indicate that gold is present in a free state rather than encapsulated, suggesting the potential for high recovery rates during milling, although further metallurgical studies are required to quantify this.

Key Details

• Study Scope: LIBS analysis performed by ECORE on mineralized core from holes NO-25-07 (shallow) and NO-25-13 (deepest high-grade interval on Zone 1 to date).
• Mineralogical Associations:
  • Precious metals (gold and silver) are consistently observed together.
  • Strong relationship identified between precious metals and sulphide minerals.
  • Most abundant sulphide: Pyrrhotite.
  • Less abundant sulphides: Arsenopyrite and Pyrite.
  • Precious minerals observed in close proximity to pyrrhotite, arsenopyrite, quartz, ankerite, sericite, and albite.
• Alteration Patterns:
  • Zone 1 alteration assemblage: Quartz, ankerite, sericite, and albite.
  • Zone 1 border alteration assemblage: Chlorite, iron oxide, siderite, and quartz.
  • The alteration pattern within the mineralized zone differs significantly from its periphery.
• Metallurgical Implications:
  • Gold appears to be in a "free state," finely disseminated, and not encapsulated within specific minerals.
  • This suggests gold could be easily liberated during the milling process, potentially leading to high recovery rates.
  • Note: Final metallurgical studies are needed to quantify the actual recovery rate.
• Current Operations & Future Plans:
  • Three drill rigs are currently active on the property with permits fully secured.
  • Drilling is focused on infilling and extending Zone 1, as well as testing new targets in the western portion of the property (historical gold discoveries from the 1980s/90s).
  • 2026 Drill Program Target: 13,000 to 14,000 metres of core in 26 holes, subject to weather conditions.
• Referenced Previous Releases: The company cites drill results from releases dated Sept. 8, 2025; July 15 and 29, 2025; June 2, 10, and 16, 2025; and May 12, 21, and 26, 2025.

Notable Quotes

• Louis Morin, CEO: "Zone 1 on Noyell continues to deliver very positive news for gold. The completed LIBS study gives Opus One a real boost for the future. As a first mineralogical/metallurgical observation, it appears that gold encountered in Zone 1 is found in a free state, finely disseminated and in close proximity to sulphide minerals, therefore a potential good recuperation rate seems achievable should gold production ever become possible. Although more studies will be carried out to confirm our interpretation, things look very good for Noyell gold project as a whole."
