Radisson Mining Resources reports exploration and development activity for the 100%-owned O'Brien Gold Project in the Abitibi region of Québec. Company announcements focus on step-out drilling beneath the historic O'Brien gold mine, high-grade gold assay results, vein-hosted mineralization, geological modelling, and updates to mineral resource estimates.
Recurring developments also include metallurgical and preliminary economic assessment work tied to processing and project planning, site-operating updates, warrant exercises and other financing activity, and board or governance changes. The news record centers on how Radisson defines the scale, continuity, and potential development path of gold mineralization at O'Brien.
Radisson Mining (OTCQX:RMRDF) reported record drill results from its 100%-owned O'Brien Gold Project in Quebec. Hole OB-26-385W4 returned 1,603.95 g/t gold over 1.0 m within 316.31 g/t over 5.1 m, the highest assay in the project's history and potentially a new high-grade Pontiac Formation zone outside current mineral resources.
Two other holes, OB-26-384W1 (Trend #1) and OB-26-386W3 (Trend 1–2 Gap), delivered multiple high-grade intercepts between ~1,600–1,700 m depth. These results form part of a 140,000 m step-out drill program with eight rigs and contribute to an 81% overall success rate of holes returning >3 g/t gold.
Radisson (OTCQX:RMRDF) reported new deep step-out drill results from its 100%-owned O'Brien Gold Project in Quebec, with eight rigs active. Key hole OB-26-378W3 at O'Brien Mine East intersected at least five mineralized zones over an aggregate 36 m at 1,720 m vertical depth.
OB-26-378W3 returned intervals such as 4.06 g/t Au over 13.1 m and 3.52 g/t Au over 13.0 m, while OB-26-385W3 cut 178.69 g/t Au over 1.1 m. Drilling is extending mineralization beyond the March 2026 MRE and into previously untested gaps.

Radisson Mining (OTCQX:RMRDF) reported new high-grade assays from the O'Brien Gold Project’s under-drilled Trend 1-Trend 2 Gap in Quebec. Six of seven holes hit significant gold intercepts, including 7.57 g/t Au over 9.7 m and multiple 1.0 m intervals above 60 g/t Au.
These results come from a 140,000 m step-out drill program testing mineralization down to 2 km, with plans to extend to 2.5 km. Historic and recent drilling together show strong vertical and emerging lateral continuity of gold-bearing veins, supporting potential future mineral resource updates and mine design optimization.
Radisson (OTCQX: RMRDF) reported assay results from 16 new drill holes at the 100%‑owned O'Brien Gold Project on April 30, 2026. Pilot hole OB-26-384 reached 1,900 metres vertical depth, returning multiple high‑grade intercepts including 4.54 g/t Au over 12.0 m and higher-grade one‑metre intervals.
The results extend mineralization below the March 2026 Mineral Resource Estimate and form part of a 140,000‑metre step‑out drill program with seven active rigs and ongoing wedge drilling.
Radisson Mining Resources (OTCQX: RMRDF) appointed Michel Leclerc P.Eng. to its Board of Directors, effective April 20, 2026. Leclerc brings more than 35 years of mining experience, including nearly 20 years at Agnico Eagle where he served as Vice President, Project Evaluation (2012–2020).
