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 Resources (RMRDF) reported nine drill holes extending gold mineralization beneath and adjacent to the former O'Brien mine in Québec. The results form part of its ongoing 140,000-metre step-out drilling program, which tests areas beyond existing mineral resources.
In Pontiac Group rocks, OB-25-377W6 intersected 44.18 grams per tonne gold over 1.3 metres, while OB-26-394 returned 3.21 grams per tonne over 11.0 metres. In Piché Group rocks, OB-26-394W2 returned 3.47 grams per tonne over 7.6 metres and 3.40 grams per tonne over 10.4 metres. These lengths are measured along drill core.
Eight of the nine holes met the program's mineralization criteria; the cumulative success rate is 83% across 137 holes. Pontiac intercepts span more than 700 metres along strike, but drilling is insufficient to establish their continuity, common structural controls or potential to become mineral resources.
Radisson Mining Resources (RMRDF) appointed Simon Gélinas as Vice President, Operations to manage its planned underground exploration program at O'Brien.
Preliminary engineering and design have begun for an access ramp and infrastructure reaching an expected vertical depth of 300 metres. Permitting is planned during 2027, with community information sessions starting in December 2026. No mining stopes will be developed; development work is expected to recover several thousand tonnes of mineralized material for processing and gold recovery. The ongoing 140,000-metre step-out drilling program will continue in parallel.
Radisson expects funding from existing treasury, anticipated tax recoveries and gold-sale proceeds from development material. Warrant exercises generated $2,009,259.47. Appointment-related compensation includes 800,000 stock options and 200,000 restricted share units.
Radisson Mining Resources (RMRDF) reported new high-grade drill results from eight holes at its 100%-owned O'Brien Gold Project on September 21, 2026.
All eight holes intersected significant gold mineralization, with standout intercept OB-26-385W5 returning 68.24 g/t Au over 6.2 metres, including 384.01 g/t Au over 1.0 metre. Other highlights include 27.27 g/t Au over 3.3 metres and 8.14 g/t Au over 5.5 metres from separate holes. These results occur within multiple quartz-sulphide-gold veins over a now 1,000‑metre vertical interval beneath the former O'Brien mine.
The ongoing step-out drill program totals 140,000 metres with eight rigs and has delivered “hits” (>3 g/t Au) in 106 of 128 holes (an 83% success rate), including 100% for the current eight-hole batch. Mineralization, including the “O’Brien Mine East” and “Trend 1” zones, has been traced to approximately 1.9 kilometres vertical depth and remains open in all directions.
Radisson Mining Resources (RMRDF) will participate in the inaugural Gentile Mining Investor Forum, a full-day mining investor conference in London on October 19, 2026, at 116 Pall Mall, Mayfair.
The event, curated by mining investor Michael Gentile with Amvest Capital, will host up to 150 investors, family offices, wealth managers and sector-focused high-net-worth individuals, with structured one-on-one meetings and issuer showcases featuring over 20 companies from Gentile's portfolio, including Radisson. Radisson President and CEO Matt Manson highlighted the O'Brien Gold Project, noting a fully-funded 140,000-metre step-out drill program with eight rigs and a recently completed C$57 million investment by Agnico Eagle Mines to support an advanced underground exploration program.
Radisson Mining Resources (RMRDF) reported new high-grade gold intercepts from six wedge drill holes in the “Trend 1–Trend 2 Gap” at its 100%-owned O’Brien Gold Project in Quebec.
Key results include hole OB-26-386W4 with 52.34 g/t Au over 3.0 m including 154.95 g/t Au over 1.0 m, plus 3.82 g/t Au over 10.2 m and 9.39 g/t Au over 2.0 m. Hole OB-26-387W7 returned 10.62 g/t Au over 4.7 m including 40.90 g/t Au over 1.1 m and 29.34 g/t Au over 1.0 m. Additional holes reported intercepts such as 5.37 g/t Au over 4.2 m and 6.14 g/t Au over 3.7 m.
Thirteen of fifteen holes drilled from two pilot holes in this 800-metre vertical gap now show grades and thicknesses consistent with existing mineral resources, suggesting lateral continuity of mineralization between Trends 1 and 2. These results form part of a 140,000-metre fully funded step-out drill program, currently using eight rigs, aimed at expanding mineral resources beyond the March 2026 Mineral Resource Estimate. Since December 2024, 98 of 120 drill holes at O’Brien have returned >3 g/t Au intercepts, an 82% success rate.

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.
