Radisson Mining Resources Inc. (TSX-V: RDS, OTCQX: RMRDF) 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 mineralised 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 mineralisation hosted within Piché Group rocks beneath the former mine workings (“O’Brien Mine East”). The intercept, characterised by extensive visible gold, 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 mineralisation, outside the scope of the main mineral resources and previously unrecognised. Highlights of the three holes released today include:
- O’Brien Mine East: OB-26-385W4 intersected 316.31 g/t Au over 5.1 metres (core length) including 1,603.95 g/t Au over 1.0 metre and 3.97 g/t Au over 5.0 metres including 10.47 g/t Au over 1.3 metres.
- Trend #1: OB-26-384W1 intersected 46.22 g/t Au over 3.9 metres including 132.28 g/t Au over 1.3 metres and 2.72 g/t Au over 17.5 metres including 10.81 g/t Au over 2.0 metres and 2.39 g/t Au over 29.0 metres including 6.08 g/t Au over 2.5 metres.
- Trend #1-Trend #2 Gap: OB-26-386W3 intersected 8.60 g/t Au over 2.6 metres including 13.87 g/t Au over 1.5 metres and 2.74 g/t Au over 11.4 metres including 14.64 g/t Au over 1.1 metres.
“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,” Matt Manson, President and CEO said. “The former O’Brien Gold Mine had a reputation for extremely high-grade gold mineralisation. 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. 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 mineralised 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 mineralisation 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 mineralisation outside of the scope of the Project’s current mineral resources. Also in this news release, drill hole OB-26-384W1 has returned multiple intercepts of high-grade mineralisation in classic quartz vein/alteration packages at the Project’s Trend #1, filling in the deep extension of this important target area between 1,600 and 1,700 metres depth. Together, the results published today reinforce three key exploration themes at O’Brien: the potential for new high-grade mineralisation in Pontiac rocks; continued extension of O’Brien gold mineralisation and mineral resources at depth, and; additional mineralisation within previously under-drilled gaps. Drilling continues with eight rigs active.”
