Radisson Mining Resources Inc. Drives Significant Resource Growth at O’Brien Gold Project

Radisson Mining Resources Inc. (TSXV: RDS; OTCQB: RMRDF) has unveiled a markedly improved Mineral Resource Estimate (MRE) for its 100‑per‑cent owned O’Brien Gold Project in Quebec’s Abitibi region. The update, released on March 2 2026, comes after a fully‑funded 140 km step‑out drilling program that is still underway and demonstrates the company’s commitment to unlocking the true potential of a historically modest gold deposit.

Drilling Success and Updated Resource Numbers

The company reports an 82 % increase in Inferred Mineral Resources, rising to 1.69 million ounces (Moz) contained in 10.37 million tonnes (Mt) at an average of 5.08 g/t Au. Indicated resources have also grown by 8 %, now totaling 0.63 Moz in 3.49 Mt at 5.59 g/t Au. These figures are calculated using a conservative 2.2 g/t Au cut‑off and a gold price assumption of US$2,500/oz.

The step‑out program has been remarkably effective, achieving an 84 % success rate in intersecting quartz‑sulphide‑gold veins with grades and thicknesses comparable to those reported in the updated MRE. Only 25 % of the 140 km program has been completed, yet the data already paint a clear picture of an extensive vein system that extends well below the historic mine workings.

Implications for Future Development

Matt Manson, President and CEO, stresses that the updated MRE provides a solid foundation for modern mine development. By moving beyond the narrow focus on high‑grade, low‑volume ore‑shoots that characterized the original 1957 operation, Radisson now presents O’Brien as an extensive, mechanisable vein deposit. The company’s geological model and capping strategy indicate that the deposit is open at depth, with an exploration target of an additional 5–10 Mt at 4–6 g/t Au up to a depth of 2 km.

Strategic Context

Radisson’s primary focus remains the acquisition, exploration, and development of mineral projects, with a particular emphasis on gold projects in north‑western Quebec and Ontario. The company’s market capitalisation stands at CAD 337 million, and its share price as of February 23 , 2026 was CAD 0.78, with a 52‑week high of CAD 0.97 and a low of CAD 0.28. Despite the volatile nature of the venture‑cap market, the recent resource upgrade is a significant step toward creating tangible shareholder value.

Conclusion

Radisson Mining Resources Inc. has delivered a compelling case for the expansion of the O’Brien Gold Project. The dramatic increase in inferred and indicated resources, coupled with the company’s robust drilling program and forward‑looking development strategy, positions Radisson as a noteworthy player in Canada’s gold mining landscape. Stakeholders and analysts alike will be watching closely as the company translates these resource gains into a viable, high‑throughput mining operation in the coming years.
