Executive Summary

  • Radisson Mining released assay results from fifteen step‑out drill holes at the O’Brien Gold Project, all intersecting gold mineralization with several high‑grade intercepts (e.g., 8.41 g/t Au over 2.2 m; 14.40 g/t Au over 1.2 m).
  • The results extend known mineralization east of the historic mine and up to ~300 m deeper than previous resources, supporting the company’s exploration target of 3–4 Moz Au at 4.5‑8.0 g/t.
  • No change to existing resource estimate disclosed; however, the data provide material insight for an upcoming updated technical report and potential resource growth.

Key Details

  • Hole OB-24-363: 8.41 g/t Au over 2.20 m (incl. 14.40 g/t Au over 1.20 m; 9.07 g/t Au over 1.80 m).
  • Hole OB-24-354: 7.95 g/t Au over 2.30 m (incl. 14.85 g/t Au over 1.0 m).
  • Hole OB-24-364: 12.75 g/t Au over 1.40 m; 11.15 g/t Au over 1.50 m.
  • Hole OB-24-361: 3.50 g/t Au over 5.0 m (incl. 8.96 g/t Au over 1.28 m; 15.10 g/t Au over 1.0 m).

  • Hole OB-25-371W1: 5.66 g/t Au over 3.0 m (incl. 9.97 g/t Au over 1.5 m).

  • Additional intercepts (Table 1 & Table 2) show numerous sub‑grade to high‑grade intervals across Trends #0‑#5, with grades ranging from ~1 g/t to >27 g/t Au in deeper wedge extensions.

  • Exploration Target Statement: Company estimates a target of 3–4 Moz Au contained in 15–20 Mt at 4.5‑8.0 g/t, based on the hypothesis that mineralization extends to ~2 km depth.

  • QA/QC: NQ core size; fire assay with AA finish; >10 g/t samples re‑assayed by gravimetric method; blanks, duplicates, and standards included.

  • Qualified Persons: Richard Nieminen, P.Geo (geological consultant) and Luke Evans, M.Sc., P.Eng. (resource model).

  • Contextual Note: Results are outside the scope of the July 9 2025 Preliminary Economic Assessment but reinforce the “step‑out” exploration strategy aimed at expanding the resource base before a future updated technical report.

Notable Quotes

“Our ongoing drilling at the O'Brien Project is focussed on ‘proof‑of‑concept’ step‑outs designed to test the full scope of the Project beyond previous drilling… Today's results continue to support this thesis.” – Matt Manson, President & CEO
