Radisson Mining Resources Inc. (TSX-V: RDS, OTCQB: RMRDF) ('Radisson' or the 'Company') is pleased to announce results from the first 3 drill holes (or 1,240 metres ('m')) of an ongoing drill program at its 100% owned O'Brien gold project located along the Larder-Lake-Cadillac Break, halfway between Rouyn-Noranda and Val-d'Or in Quebec, Canada.

Key Highlights: OB-23-284 intersected 81.83 grams per tonne ('g/t') gold ('Au') over 3.00 m

OB-23-283 intersected 6.16 g/t Au over 3.00 m and 5.17 g/t Au over 4.40 m

Successful start confirms Inferred resource growth potential in the upper 500 m

Program well underway with 12 drill holes completed, for 5,820 m drilled, to date

4,570 m of assays pending from 9 drill holes on Trend 3 and 4

'We are pleased to report that initial results from our ongoing 10,000 m drill program have successfully intersected high-grade mineralization demonstrating strong resource growth potential in the upper 500 m of the O'Brien deposit,' commented Chairman of the Board of directors and Interim President & CEO, Denis Lachance. 'Drilling at O'Brien continues to deliver high grades, consistent with drill results obtained over the last several years and those included within the current mineral resource estimate, which exceed 10 g/t gold on an Indicated resource basis. We're also pleased to see world-class gold grade as in hole OB-23-284. This is the type of high-grade mineralization that made the historic O'Brien mine so profitable and has the potential to deliver very strong margins in a future mining operation. We expect significant news flow as more results become available and we look forward to sharing additional details of the drill program expansion in the coming weeks.'

Targeting completed during Phase 1

Phase 1 of the drill program was designed with the objective of growing Inferred resources in areas with strongest veining and grade continuity within the first 500 m below surface, between Trends 0 and Trend 4.
