Radisson Mining Resources Inc. announced that it has expanded its drill program to approximately 35,000 metres ("m") at its high-grade O'Brien Gold Project located along the Larder-Lake-Cadillac Break, halfway between Rouyn-Noranda and Val-d'Or in Quebec, Canada. Expanded Drill Program Highlights: 60-70% of drilling will focus on resource expansion between Trends 0 and 4; Approximately 15,000 m for 27 drill holes; 30-40% of drilling will focus high-priority step-out and exploration targets; Historic O'Brien Deep and Trend 1 Deep: 8,200 m for 6 holes; New Alger target: 2,400 m for 5 holes; Fully-funded for 35,000 m Program (22,000 m left to complete); To date 24 drill holes have been completed for a total of 12,960 m; Assays are pending for 5,804 m in 11 drill holes, including 8 intersections of visible gold on Trend 1, 2 and 3. With approximately $6.5 m1 in treasury, Radisson is fully-funded to complete the remaining portion of the 35,000 m drill program. This substantial expansion to the drill program will allow the company to accelerate both resource expansion and exploration efforts, simultaneously.

The expanded program will dedicate 60-70% of drilling to growing the current resources in the near high-grade mineralized zones. Concurrently, the Company will prioritize a high-potential 2-kilometre ("km") target outlined earlier in 2024 in the north-west region of the 74 km2 New Alger area with the objective of making a new discovery. In addition, the Company will be drill-testing below the historic O'Brien Mine underground workings and, 300 metres below the current resources, on Trends 0 and 1. This two-pronged approach underscores Radisson's commitment to unlocking the full value of the highly prospective O'Brien Gold project through resource growth and further exploration upside.

A total of 24 drill holes (12,960 m) have been completed to date as part of the initial phase of the program. The Company expects to report additional assay results from Phase I in the coming weeks. With approximately 2.5 km of ground along the prolific LLCB having seen limited exploration work in recent years, O'Brien West also remains open in all directions.

Exploration targets, following on an historic intercept of 5.63 g/t Au over 9.00 m, have been established on this sector and are expected to eventually be integrated into the drill program.
