Radisson Reflects on a Successful 2025 and Provides 2026 Outlook

Radisson Mining Resources Inc. has delivered a comprehensive review of its 2025 exploration achievements at the O'Brien Gold Project in Quebec's Abitibi region, highlighting the success of an aggressive deep drilling strategy that began in late 2024. The company's approach was based on the thesis that the mineralizing system, previously delineated only at shallow levels, could extend significantly deeper than historical work suggested.

The standout result from the 2025 program came from drill hole OB-24-337, which marked the first drilling below the final stope of the historic mine since operations ceased in 1957. This pioneering hole intersected exceptional grades of 31.24 g/t gold over 8.0 metres, including a spectacular 242.0 g/t gold over 1.0 metre, at a vertical depth of 1,500 metres. This result validated the company's deep exploration thesis and demonstrated the potential for significant mineral resource expansion at depth.

The company has been operating continuously for over 12 months from this initial pilot hole, suggesting sustained exploration activity and systematic approach to testing the deep mineralization potential. The success of the step-out drilling beneath both existing mineral resources and the historic mine workings indicates that O'Brien may host a substantially larger gold system than previously understood.

Looking ahead to 2026, Radisson is positioned to execute its largest ever drill program at O'Brien, supported by the company's strongest treasury position to date. This financial strength provides the foundation for an expanded exploration campaign that could further define the scale and continuity of the deep gold mineralization, potentially transforming the project's resource profile and development trajectory.
