ROUYN-NORANDA, Quebec, Oct. 30, 2024 (GLOBE NEWSWIRE) -- Radisson Mining Resources Inc. (TSX-V: RDS, OTCQB: RMRDF) (“Radisson& or the “Company&) is pleased to announce results from 10 diamond drill holes completed at its 100%-owned O&Brien Gold Project (“O&Brien& or the “Project&) located in the Abitibi region of Québec. These results are part of Radisson&s ongoing 35,000 metre drill program.

The ten drill holes reported today represent both shallow and deep drilling on the Project&s mineralized “Trend #s 0, 1 and 2.& Included are two wedges performed on the deep drill hole OB-24-324, which returned 27.61 g/t gold over 6.0 metres with extensive visible gold at a depth 170 metres below the base of the existing Mineral Resource on “Trend #1& (see Radisson News Release dated September 24, 2024). Also reported today are results from drill hole OB-24-323 which represents a 100-metre step-out below the base of the Mineral Resource on “Trend #0.& The new data, taken together, continue to demonstrate the extension of high-grade O&Brien mineralization to depth, where it remains open.

Results Highlights:

• OB-24-332 intersected 16.21 grams per tonne (“g/t&) gold (“Au&) over 5.4 metres, including 32.25 g/t Au over 2.4 metres, and a separate mineralized interval of 4.18 g/t Au over 5.3 metres, including 10.10 g/t Au over 1.0 metre;
• OB-24-324W1, a wedge from drill hole OB-24-324, intersected 5.48 g/t Au over 12.4 metres, including 12.10 g/t Au over 4.4 metres, and a separate mineralized interval of 3.09 g/t Au over 15.2 metres, including 8.02 g/t Au over 4.0 metres;
• OB-24-323 intersected 3.34 g/t Au over 10.9 metres, including 13.90 g/t Au over 1.5 metres, and a separate mineralized interval of 3.51 g/t Au over 8.2 metres, including 9.93 g/t Au over 1.5 metres;
• OB-24-330 intersected 19.89 g/t Au over 2.5 metres; and
• OB-24-333 intersected 62.00 g/t Au over 1.0 metre.
  

Matt Manson, President & CEO, commented: “Today&s drill results continue to demonstrate the type of narrow high-grade intercepts within broader mineralized envelopes that are so characteristic of the O&Brien Gold Project. The drill holes reported today represent a balance between shallower targets within the existing Mineral Resource model, and deeper step-outs geared to new discovery. This reflects the drilling priorities set in May when our 2024 program was expanded to 35,000 metres; however, we are becoming increasingly focused on the deep expansion potential of O&Brien. Recall that DDH OB-24-324, released in September, returned almost an ounce of gold over 6 metres core length at 1,100 metres vertical depth, 170 metres below previous drilling. For context, approximately 75% of our existing Mineral Resource is defined at depths above 600 metres. Now, wedges drilled from this hole, and a step out hole 100 metres below the Mineral Resource on Trend #0, are giving more high-grade intercepts at previously untested depths. Three rigs are currently active, with one rig committed to drilling directly beneath the historic O&Brien mine for the first time in the Project&s history. This pilot hole is expected to be more than 1,600 metres in length and will test for gold mineralization more than 400 metres beneath the deepest mine workings. Success with this hole offers to dramatically change the potential scope of the Project.&

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 30-70% 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. Drill holes OB-24-324W2 and 329 did not return any intercepts averaging above 3.00 g/t Au. Assay results for drill holes OB-24-327 and 328 are pending.

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.

Based on the modern drilling, 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.

Current exploration is focused 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,& Table 1 and Figures 1 and 2).

Today&s Drill Results

Today&s results are from ten drill holes, including two wedges, over 3,895 metres in Trends # 0, 1 and 2. Visible gold was observed in six of the holes. Holes were drilled on northerly declinations at initial inclinations of between -50 and -80 degrees, providing a high angle of incidence with the southerly dip of the Piché Group rocks and the vein mineralization. Estimated true widths of drill intercepts at the point of contact with mineralization is estimated to be 30-70% of core length.

Drill holes OB-24-324W1 and W2 were wedges drilled off the previously reported, high-grade hole OB-24-324, which had extended Trend #1 170 metres beneath previous drilling with two zones of 27.61 g/t Au over 6.0 metres and 6.83 g/t Au over 10.0 metres, including 40.2 g/t Au over 1.5 metres (Figure 2). Wedge OB-24-324W1 successfully intersected two zones of mineralization immediately above hole 324, with 5.48 g/t Au over 12.4 metres, including 12.10 g/t Au over 4.4 metres, and 8.02 g/t Au over 4.2 metres. Wedge OB-24-324W2 deviated from its intended target eastwards and returned a number of mineralized zones of 1-2 metres in thickness at 1-2 g/t in gold grades (Table 2).

Drill holes OB-24-325 to 332 tested targets within the existing vein model in Trend #1, between approximately 200 and 350 metres vertical depth. Of note, OB-24-332 returned 16.21 g/t Au over 5.4 metres, including 32.25 g/t Au over 2.4 metres. Drill hole OB-24-333 was a shallow hole targeting Trend #2 at approximately 200 metres vertical depth, returning 62.0 g/t Au over 1.0 metre. Results are pending for drill holes OB-24-327 and 328.

Drill hole OB-24-323 was located approximately 100 metres below drilling on the high-grade Trend #0, immediately adjacent to the O&Brien mine. It returned two broad mineralized zones of 3.34 g/t Au over 10.9 metres, including 13.90 g/t Au over 1.5 metres, and 3.51 g/t Au over 8.2 metres, including 9.93 g/t Au over 1.5 metres. This successfully extends Trend #0 to depth.

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, Québec. 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.
