Radisson Reports Highest Grade Drill Intercepts Achieved to Date Beneath the Historic O’Brien Gold Mine Including 89.36 g/t Gold over 3.7 Metres and 60.75 g/t Gold over 2.1 Metres

Radisson Mining Resources Inc. has reported breakthrough assay results from its wholly-owned O'Brien Gold Project in Quebec's prolific Abitibi greenstone belt, marking a significant milestone in the company's exploration program. The latest drill campaign has yielded the highest grade gold intercepts ever achieved beneath the historic O'Brien mine, with standout results including 89.36 g/t gold over 3.7 metres and 60.75 g/t gold over 2.1 metres.

These exceptional grades underscore the robust mineralization potential that exists in the deeper extensions of the historic O'Brien system, which has previously produced over 587,000 ounces of gold at an average grade of 15.25 g/t. The fact that these represent the highest grades encountered to date suggests the company may be approaching the heart of a significant mineralized system, potentially indicating proximity to high-grade ore shoots that could substantially enhance the project's economic profile.

For the broader Quebec mining sector, these results reinforce the Abitibi region's status as one of Canada's premier gold camps and highlight the continued exploration upside in mature mining districts. The success at O'Brien demonstrates that systematic exploration beneath historic mines can unlock significant value, particularly in regions with established infrastructure and proven geological systems.

The timing of these results is particularly significant as gold markets remain strong and investor interest in high-grade Quebec gold projects continues to intensify. Should follow-up drilling continue to deliver similar grades and expand the mineralized envelope, Radisson could be positioning itself for a potential resource upgrade that would meaningfully advance the O'Brien project toward development consideration.
