Radisson Mining Resources Inc. announced drill results and the acceleration of the ongoing drill program, with the mobilization of a second drill rig, to 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. Highlights: Drill program well underway with 22 drill holes (11,808 metres) completed, to date; 5,165 metres of assays still pending from 9 drill holes on Trends 2 and 3; Several broader intervals of gold mineralization intersected in Pontiac Sediments coupled with multiple historical diamond drill hole intervals open up new opportunity; Radisson well-funded to expand drill program with more than $7.0 million in treasury. Key High-Grade Highlights: OB-23-286 intersected 9.70 g/t Au over 4.00 m2; OB-23-289 intersected 6.54 g/t Au over 4.50 m, including 10.02 g/t Au over 2.20 m; and OB-24-305 intersected 6.40 g/t Au over 4.00 m. Key Bulk Intersection Highlights: OB-24-306 intersected 0.84 g/t Au over 49.70 m, including 3.97 g/t Au over 8.20 m and OB 23-288 intersected 0.70 g/t Au over 28.90 m, including 3.96g/t Au over 4.50 m. Results published are from nine drill holes completed on Trend 4, a sector where current resources are limited to the first 400 vertical metres from surface.

New and previously released drill holes demonstrate continuity of high-grade mineralization down to a vertical depth of 550 m in this area, which remains open for expansion over 750 m, both laterally and at depth. In addition to the high-grade mineralization targeted in the Piché Group, which comprises most of the mineral resource estimate, several broad intervals of gold mineralization were obtained in the Pontiac Sediments to the south, which were not previously known to host such mineralization. Based on these results, the Radisson team reviewed drill holes from previous campaigns and was able to identify several other additional broad intervals of mineralization in the Pontiac Sediments.

To further support the interpretation of the findings, samples from twelve additional intervals from historical drill holes where similar veining was observed yet never assayed, will also be collected and assayed. Targeting Completed During Phase 1: Phase 1 of the drill program was designed to grow Inferred resources in areas with strongest veining and grade continuity within the first 500 m below surface, between Trends 0 and Trend 4. Radisson has completed 11,808 m since the commencement of the program in September 2023 and expects to provide further details about the expansion of the drill program while reporting additional results in the coming weeks. With the resource modeling and the compilation of historical gold values from the historic O?Brien mine, the vein?s behaviour and gold distribution along each vein are well understood, allowing for efficient targeting of high-grade vectors that extend for over 400 m vertically in some cases.

The intercepts published, in combination with previous results from this program support this concept in areas targeted for resource growth. 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 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.
