With Step-Out Drilling Continuing, Radisson Demonstrates Meaningful Resource Growth at O'Brien with an Updated Mineral Resource Estimate

Core Insights - Radisson Mining Resources Inc. has reported an updated Mineral Resource Estimate (MRE) for its O'Brien Gold Project, showing significant increases in both Indicated and Inferred Mineral Resources due to recent drilling successes [1][10][18] Group 1: Mineral Resource Estimate Details - The updated MRE indicates an 82% increase in Inferred Mineral Resources, now totaling 1.69 million ounces (10.37 million tonnes at 5.08 grams per tonne gold) [10][14] - Indicated Mineral Resources have increased by 8% to 0.63 million ounces (3.49 million tonnes at 5.59 grams per tonne gold) [10][14] - The estimates are based on a cut-off grade of 2.2 grams per tonne gold and a gold price assumption of US$2,500 per ounce [5][10] Group 2: Drilling Program and Future Plans - The company is conducting a fully-funded 140,000-metre step-out drill program aimed at exploring mineralization to a depth of 2 kilometres, with 72,500 metres planned for 2026 and 32,500 metres for the first half of 2027 [1][22] - The ongoing drilling campaign has achieved an impressive 84% success rate in intersecting quartz-sulphide-gold veins [1][10] - An Exploration Target of an additional 5 million to 10 million tonnes at grades between 4.0 grams per tonne and 6.0 grams per tonne gold is anticipated [15][20] Group 3: Historical Context and Project Vision - The former O'Brien Mine was known for high-grade ore, with mining ceasing in 1957 when gold was priced at US$35 per ounce, leaving significant volumes of lower-grade mineralized material unmined [1][17] - The updated MRE reflects a shift in perspective, presenting the project as a substantial vein deposit suitable for modern mechanized mining rather than a high-grade, limited-scale deposit [1][18] - Existing mining infrastructure, including a shaft extending to 1,000 metres depth and multiple regional mills, supports the potential for future development [18][26]
