Radisson Announces Additional High-Grade Drill Results at O’Brien,

Radisson Mining Resources Inc. (TSX-V: RDS, OTCQB: RMRDF)(“Radisson” or the “Company”) is pleased to announce results from [10] diamond drill holes completed at its 100%-owned O’Brien Gold Project (“O’Brien” or the “Project”) located in the Abitibi region of Québec. These results are part of Radisson’s ongoing 35,000 metre drill program.

The ten drill holes reported today represent both shallow and deep drilling on the Project’s mineralized “Trend #s 0, 1 and 2.” Included are two wedges performed on the deep drill hole OB-24-324, which returned 27.61 g/t gold over 6.0 metres with extensive visible gold at a depth 170 metres below the base of the existing Mineral Resource on “Trend #1” (see Radisson News Release dated September 24, 2024). Also reported today are results from drill hole OB-24-323 which represents a 100-metre step-out below the base of the Mineral Resource on “Trend #0.” The new data, taken together, continue to demonstrate the extension of high-grade O’Brien mineralization to depth, where it remains open.

Results Highlights:

• OB-24-332 intersected 16.21 grams per tonne (“g/t”) gold (“Au”) over 5.4 metres, including 32.25 g/t Au over 2.4 metres, and a separate mineralized interval of 18 g/t Au over 5.3 metres, including 10.10 g/t Au over 1.0 metres;
• OB-24-324W1, a wedge from drill hole OB-24-324, intersected 5.48 g/t Au over 12.4 metres including 12.10 g/t Au over 4.4 metres, and a separate mineralized interval of 3.09 g/t Au over 15.2 metres, including 8.02 g/t Au over 4.0 metres;
• OB-24-323 intersected 3.34 g/t Au over 10.9 metres, including 13.90 g/t Au over 1.5 metres, and a separate mineralized interval of 3.51 g/t Au over 8.2 metres, including 9.93 g/t Au over 1.5 metres;
• OB-24-330 intersected 19.89 g/t Au over 2.5 metres; and
• OB-24-333 intersected 62.00 g/t Au over 1.0 metre.

Matt Manson, President & CEO, commented: “Today’s drill results continue to demonstrate the type of narrow high-grade intercepts within broader mineralized envelopes that are so characteristic of the O’Brien Gold Project. The drill holes reported today represent a balance between shallower targets within the existing Mineral Resource model, and deeper step-outs geared to new discovery. This reflects the drilling priorities set in May when our 2024 program was expanded to 35,000 metres; however, we are becoming increasingly focussed on the deep expansion potential of O’Brien. Recall that DDH OB-24-324, released in September, returned almost an ounce of gold over 6 metres core length at 1,100 metres vertical depth, 170 metres below previous drilling. For context, approximately 75% of our existing Mineral Resource is defined at depths above 600 metres. Now, wedges drilled from this hole, and a step out hole 100 metres below the Mineral Resource on Trend #0, are giving more high-grade intercepts at previously untested depths. Three rigs are currently active, with one rig committed to drilling directly beneath…
