Radisson Mining Resources Inc. announced to present an overview of ongoing geological modelling at its 100%-owned O'Brien Gold Project located in the Abitibi region of Quebec. This news release focusses on significant new vein-hosted mineralization beneath the historic O'Brien gold mine emerging from the Company's continuing and fully funded 140,000 metre step-out drill program. Since late 2024, fifteen drill wedges have been completed from pilot hole OB-24-337, delineating a coherent system of at least eight parallel veins demonstrating continuity of mineralization with the former mine workings.
An initial 35,000 metres of the program were completed in 2025, with 72,500 metres budgeted for 2026, and a further 32,500 metres scheduled for the first half of 2027. The scope of the drill program is broad, with up to eight rigs to be deployed to drill beneath the breadth of the former mine ("O'Brien Mine East" and "West"), beneath the modern mineral resources to the east ("Trend #s 1 to 4"), and at the Thompson-Cadillac area west of the O'Brien mine, which will be drilled for the first time since 2021. objectives will be reassessed progressively based on results obtained.
Since the program began, 84% of completed drill holes have intersected gold mineralization with grades and core-lengths consistent with the Project's Mineral Resources. A particular focus of this step-out drill program has been to explore below the principal area of historic workings ("O'Brien Mine East") where mining operations ceased in 1957 at the 1,000 metre level. In December 2024, Radisson released the results of deep pilot hole OB- 24-337 which intersected 31.24 g/t Au over 8.0 metres, including 242.0 g/t Au over 1.0 metre at approximately 1,500 metres vertical depth, 500 metres below the final mining stope.
Radisson expects to report drill results from the program on a regular basis as the 72,500 metres of drilling budgeted for 2026 progresses. Radisson further intends to update the Project's Mineral Resource Estimate on a step-by-step basis through the course of the drill program. The first such update is expected to be completed prior to the end of the first quarter of 2026.
Such factors include, among others; the risk that the O'Brien Gold Project will never reach the production stage (including due to a lack of financing); the Company's capital requirements and access to funding; changes in legislation, regulations and accounting standards to which the Company is subject, including environmental, health and safety standards, and the impact of such legislation, regulations and standards on the Company's activities; price volatility and availability of commodities; price volatility and availability of commodity prices and other other assets.
