Radisson Reports Highest-Ever Assay Result at O'Brien: 1,604 g/t (1.60 kg/t) Gold over 1.0 Metre Within 316 g/t Gold over 5.1 Metres
Rouyn-Noranda, Quebec--(Newsfile Corp. - July 7, 2026) - Radisson Mining Resources Inc. (TSXV: RDS) (OTCQX: RMRDF) ("Radisson" or the "Company") is pleased to announce the results of three new drill holes recently completed at its 100%-owned O'Brien Gold Project ("O'Brien" or the "Project") located in the Abitibi region of Québec. The three holes are from separate areas of exploration focus within the ongoing 140,000 metre step-out drill program. The results include the highest drill assay ever.

Rouyn-Noranda, Quebec--(Newsfile Corp. - July 7, 2026) - Radisson Mining Resources Inc. (TSXV: RDS) (OTCQX: RMRDF) ("Radisson" or the "Company") is pleased to announce the results of three new drill holes recently completed at its 100%-owned O'Brien Gold Project ("O'Brien" or the "Project") located in the Abitibi region of Québec. The three holes are from separate areas of exploration focus within the ongoing 140,000 metre step-out drill program. The results include the highest drill assay ever achieved in the Project's history: 1,603.95 grams per tonne ("g/t") gold ("Au") over 1 metre within a mineralized interval of 316.31 g/t Au over 5.1 metres (core lengths). This record-setting intercept is in hole OB-26-385W4, which was targeting the deep extension of vein mineralization hosted within Piché Group rocks beneath the former mine workings ("O'Brien Mine East"). The intercept, characterized by extensive visible gold (Figure 1), was observed in Pontiac Formation rocks at 823 metres downhole, before the target area was reached. It represents, potentially, a new zone of very high-grade mineralization, outside the scope of the main mineral resources and previously unrecognized. Highlights of the three holes released today (Figure 2 and Table 1) include: Matt Manson, President and CEO: "We are taking the unusual step of releasing three holes from our ongoing step-out drill program at O'Brien because of the significant nature of the results received. The former O'Brien Gold Mine had a reputation for extremely high-grade gold mineralization. Recall that in December 2024 we released a drill intercept of 1,345 g/t Au over 1.0 metre (within 643 g/t Au over 2.0 metres) interpreted as the extension of the famous O'Brien "Jewellery Box" mining stope (see Radisson news release dated December 9, 2024). Now, this result has been exceeded with 1,604 g/t Au over 1.0 metre (within 316 g/t Au over 5.1 metres) from a new mineralized zone hosted within Pontiac meta-sedimentary rocks, the formation that forms the hanging wall of the Piché rocks that host both the bulk of the Project's gold mineralization and the former mine workings. Importantly, it occurs within a cluster of previously published gold intercepts, offering the potential for a new, very high-grade zone of mineralization outside of the scope of the Project's current mineral resources.
