Radisson Intersects 81.83 g/t Gold Over 3.00 Metres on First Holes of its Phase 1 Drill Program at its O’Brien Gold Project in Quebec, Canada

ROUYN-NORANDA, Jan. 22, 2024 - 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 (see location map 1 and location map 2), 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.

As illustrated, in Figure 2 and 3, many zones can still be targeted in this superficial domain to reach a drill hole spacing of 25 m by 25 m. With the modeling of the veins and the compilation of historic gold values in the historic O'Brien mine, the vein's behaviour is well understood and, moreover, the gold distribution along each vein is also understood. The high-grade gold shoots commonly form high grade shoots with a lateral strike length of 15-20 m and a continuous vertical extent up to 400 m as illustrated on the longitudinal view of the vein V3-N_12 (See Figure 3). Intercepts published in holes OB-23-283 and OB-23-284 support this concept in areas targeted for resource growth having reached a vertical extent exceeding 130 m. Areas like these, including the area where mineralization returned 81.83 g/t Au over 3.00 m are expected to contribute significantly to resources in a future MRE update.

QA/QC

All drill cores in this campaign are NQ in size. Assays were completed on sawn half-cores, with the second half kept for future reference. The samples were analyzed using standard fire assay procedures with Atomic Absorption (AA) finish at ALS Laboratory Ltd, in Val-d'Or, Quebec. Samples yielding a grade higher than 5 g/t Au Au were analyzed a second time by fire assay with gravimetric finish at the same laboratory. Mineralized zones containing visible gold were analyzed with metallic sieve procedure. Standard reference materials, blank samples and duplicates were inserted prior to shipment for quality assurance and quality control (QA/QC) program.
