ROUYN-NORANDA, Québec, Aug. 14, 2024 (GLOBE NEWSWIRE) — Radisson Mining Resources Inc. (TSX-V: RDS, OTCQB: RMRDF) (“Radisson” or the “Company”) is pleased to announce additional results from eleven diamond drill holes completed at its 100% owned O’Brien Gold Project (“O’Brien” or the “Project”) located in the Abitibi region of Quebec (see location). These results are part of Radisson’s ongoing and fully-funded 35,000 metre drill program aimed at expanding the scope of gold mineralization and Mineral Resources at the Project.
Gold mineralization at the O’Brien Project is characterized by narrow and high-grade quartz-sulphide veins with prolific visible gold developed within rocks of the Piché Group adjacent to the Larder Lake-Cadillac Break (“LLCB”). The historic O’Brien mine produced over half a million ounces of gold from such veins at an average grade exceeding 15 grams per tonne (“g/t”), and today’s results demonstrate the same characteristic narrow and very high-grade vein intercepts.
Results Highlights:
- OB-24-320 intersected 137.00 g/t gold (“Au”) over 1.0 metres within a mineralized interval of 24.74 g/t Au over 6.0 metres, and 7.60 g/t Au over 3.0 metres within a mineralized interval of 4.61 g/t Au over 6.0 metres;
- OB-24-316 intersected 74.40 g/t Au over 1.3 metres within a mineralized interval of 42.31 g/t Au over 2.3 metres, and 8.76 g/t Au over 1.0 metres within a mineralized interval of 3.50 g/t Au over 6.1 metres;
- OB-24-317 intersected 20.20 g/t Au over 1.0 metres; and
- OB-24-313 intersected 6.47 g/t Au over 3.7 metres.
Matt Manson, President & CEO, commented: “Today’s drill results further illustrate the type of vein intercepts, very-high grades and abundant visible gold that the O’Brien Gold Project is known for. These latest results are from predominantly Trends 1 and 2, closer to the historic O’Brien mine, where we are seeing, perhaps, the best examples of the extensive high-grade near-vertical shoots that were so important for previous gold production. This is illustrated by the new drill hole OB-24-320 (137 g/t Au over 1.0 metres within a mineralized interval of 24.74 g/t Au over 6.0 metres) which is 290 metres down plunge on the same ‘Trend 1’ section and developed within the same Piche Group S3p greywackes as the previously published drill hole OB-23-284 (241 g/t Au over 1.0 metres within 81.83 g/t Au over 3.0 metres; Figures 2 & 3). Our drilling to date has been aimed at in-filling gaps in the geological model in the 200-500 metre depth range. Current drilling includes deeper step-out holes below Trends 0 and 1 and below the depth of the existing Mineral Resource. We now have two rigs at O’Brien and are approximately half-way through our fully-funded 35,000 metre drill program of resource expansion and step-out exploration. We will be reporting additional drill results on a regular basis as they become available.”

Notes on Calculation of Drill Intercepts
The O’Brien Gold Project March 2023 Mineral Resource Estimate (“MRE”) utilizes a 4.50 g/t Au bottom cutoff, a US$1600 gold price, a minimum mining width of 1.2 metres, and a 40 g/t Au upper cap on composites. Intercepts presented in Table 1 are calculated with a 3.00 g/t Au bottom cut-off, representing the lower limit of cut-off sensitivity presented in the March 2023 MRE. This methodology differs from previous Radisson disclosure, and intercepts reported in this release may not be directly comparable to historical published intercepts. Sample grades are uncapped. True widths, based on depth of intercept and drill hole inclination, are estimated to be 40-80% of core length. Table 2 presents additional drill intercepts calculated with a 1.00 g/t bottom cut-off over a minimum 1.0 metre core length so as to illustrate the frequency and continuity of mineralized intervals within which high-grade gold veins at O’Brien are developed.
Gold Mineralization at O’Brien
Gold mineralizing quartz-sulphide veins at O’Brien occur within a thin band of interlayered mafic volcanic rocks, conglomerates, and porphyric andesitic sills of the Piché Group occurring adjacent to the east-west oriented LLCB. Gold, along with pyrite and arsenopyrite, is typically associated with shearing and a pervasive biotite alteration, and developed within multiple Piché Group lithologies and, occasionally, the hanging-wall Pontiac meta-sedimentary rocks.
As mapped at the Historic O’Brien mine, and now replicated in the modern drilling, individual veins are generally narrow, ranging from several centimetres up to several metres in thickness. Multiple veins occur sub-parallel to each other, as well as sub-parallel to the Piché lithologies and the LLCB. Individual veins have well established lateral continuity, with high-grade near-vertical grade shoots developed over significant lengths. Historic gold production was derived predominantly from one such grade shoot, over a vertical extent of at least 1,000 metres and with a reported average recovered grade of over 15 g/t.
The Project has estimated Indicated Mineral Resources of 0.50 million ounces (1.52 million tonnes at 10.26 g/t Au), with additional Inferred Mineral Resources of 0.45 million ounces (1.62 million tonnes at 8.64 g/t Au). Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
Current exploration is focussed on delineating well developed vein mineralization to the east of the historic mine, with additional high-grade shoots becoming evident in the exploration data over what has been described as a series of repeating trends (“Trends 0 to 5”, Table 1 and Figures 1 and 2).
Today’s Drill Results
Today’s results are from eleven drill holes over 5,622 metres in Trends 1, 2 and 3. Visible gold was observed in eight holes, including impressive examples in holes OB-24-320 and OB-24-317 (see Figure 1). Holes were drilled on northerly declinations at inclinations of between -50 and -75 degrees, providing a high angle of incidence with the southerly dip of the Piché Group rocks and the vein mineralization. Each drill hole was targeted at gaps within the existing geological model, between depths of -200 and -500 metres where, on the basis of previous drilling, Mineral Resources were absent or of lower confidence.
QA/QC
All drill cores in this campaign are NQ in size. Assays were completed on sawn half-cores, with the second half kept for future reference. The samples were analyzed using standard fire assay procedures with Atomic Absorption (AA) finish at ALS Laboratory Ltd, in Val-d’Or, Quebec. Samples yielding a grade higher than 5 g/t Au were analyzed a second time by fire assay with gravimetric finish at the same laboratory. Mineralized zones containing visible gold were analyzed with metallic sieve procedure. Standard reference materials, blank samples and duplicates were inserted prior to shipment for quality assurance and quality control (QA/QC) program.
