Radisson Announces Additional Assay Results from 2024 Drill Program at O'Brien Including 8.36 g/t Gold over 15 Metres
Rhea-AI Summary
Radisson Mining Resources (TSXV: RDS, OTCQB: RMRDF) has announced new drill results from its 2024 drill program at the O'Brien Gold Project in Quebec. The program, consisting of 35,000 metres, revealed significant gold intersections including 8.36 g/t gold over 15.0 metres in hole OB-24-358 and 10.32 g/t Au over 4.1 metres in hole OB-24-327.
The results come from seventeen drill holes focused on shallow drilling within the existing Mineral Resource area across Trends 1, 2, and 3. The project demonstrates characteristic narrow, high-grade gold mineralization within quartz-sulphide veins. The O'Brien Project currently holds Indicated Mineral Resources of 0.50 million ounces (1.52 million tonnes at 10.26 g/t Au) and Inferred Resources of 0.45 million ounces (1.60 million tonnes at 8.66 g/t Au).
Positive
- High-grade gold intersections: 8.36 g/t Au over 15.0m and 10.32 g/t Au over 4.1m
- Successful expansion of mineralization through deep drilling below current resource
- Three drilling rigs actively operating on site for 2025 program
- Strong historical production: over 500,000 ounces at +15 g/t average grade
Negative
- Current mineral resources to 0.95M combined ounces (indicated + inferred)
- Narrow vein mineralization may impact mining costs

Rouyn-Noranda, Quebec--(Newsfile Corp. - February 26, 2025) - Radisson Mining Resources Inc. (TSXV: RDS) (OTCQB: RMRDF) ("Radisson" or the "Company") is pleased to announce additional drill assay results from its
The seventeen drill holes reported were completed as part of the 35,000 metre, 2024 drill program designed to increase the scope of gold mineralization at the Project with a combination of deep and shallow drill holes. Prior to the end of last year, Radisson released the results of several deep drill holes which demonstrated high grade mineralization at substantial step-outs below the base of the current Mineral Resource and below the historic O'Brien Mine workings (see Radisson News Releases dated September 24, 2024, October 30, 2024 and December 16, 2024). Today's results represent shallower drilling at the margins, or within, the existing Mineral Resource over the Project's "Trends 1, 2 and 3". The new data continue to demonstrate the Project's characteristic narrow and high-grade gold mineralization within quartz-sulphide veins.
Results Highlights:
OB-24-358 intersected 8.36 grams per tonne ("g/t") gold ("Au") over 15.0 metres within a broad mineralized interval with multiple veins, including 56.0 g/t Au over 1.0 metre and 41.1 g/t Au over 1.0 metre;
OB-24-327 intersected 10.32 g/t Au over 4.1 metres including 18.30 g/t Au over 1.5 metres;
OB-24-350 intersected 46.40 g/t Au over 1.0 metre;
OB-24-339 intersected 10.05 g/t Au over 1.3 metres; and
OB-24-351 intersected 9.89 g/t Au over 2.9 metres including 17.90 g/t Au over 1.4 metres
Matt Manson, President & CEO, commented: "We are reporting today results from drill holes completed during the fall as part of our 2024 drill program. They demonstrate the type of narrow high-grade intercepts within broader mineralized envelopes that are so characteristic of the O'Brien Gold Project and serve to fill out our interpretation of mineralization in and around the existing Mineral Resources. Our drilling priorities in 2024 represented a balance between shallower targets within the existing Mineral Resource model, and deeper step-outs geared to new discovery. The deep step-outs greatly exceeded our expectations. They included the deepest hole ever drilled at the Project, OB-24-337, which returned 31.24 g/t Au over 8 metres a full 500 metres beneath the historic mine workings, and OB-24-324 which returned 27.61 g/t Au over 6.0 metres 170 metres beneath the base of our "Trend #1". The results for these deep drill holes were prioritised in the laboratory, so as to guide planning for the 2025 drill program, which is almost exclusively aimed at extending O'Brien's gold mineralization to depth as well as following up on the recently re-discovered "Jewellery Box" zone. The 22,000 metre 2025 drill program is proceeding well with three rigs at site with a steady flow of results expected."

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 in contact with the east-west oriented Larder Lake-Cadillac Break ("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 and footwall Cadillac 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 near-vertical, high-grade shoots developed over significant lengths.
The historic O'Brien mine produced over half a million ounces of gold from such veins and shoots at an average grade exceeding 15 g/t and over a vertical extent of at least 1,000 metres. Recent exploration has 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 ("Trend #s 0 to 5").
Based on drilling complete to the end of 2022, 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 (1.60 million tonnes at 8.66 g/t Au). Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

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 10 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.
