Radisson intersects 4.04 g/t Au over 15.90 m, highlighting resource expansion potential at depth along high-grade trend #2 at the O’Brien Gold Project

Rouyn-Noranda, Qc Radisson Mining Resources Inc. (TSX-V: RDS, OTC: RMRDF): (“Radisson” or the “Company”) is pleased to announce significant high-grade gold intercepts from the ongoing 130,000 m exploration drill program at its 100% owned O’Brien gold project located along the Larder-Lake-Cadillac Break (see location map 1 and location map 2), halfway between Rouyn-Noranda and Val-d’Or in Quebec, Canada.

Key highlights

• Significant intercepts from resource expansion drilling along high-grade trend #2
  • OB-21-290W1
    • 4.04 g/t Au over 15.90 m including 5.24 g/t Au over 10.80 m
  • OB-21-290W3
    • 4.60 g/t Au over 4.70 m,
    • 4.81 g/t Au over 6.20 m including 8.45 g/t Au over 3.00 m and;
    • 5.80 g/t Au over 3.50 m including 10.94 g/t Au over 1.70 m
  • OB-21-290W5
    • 5.36 g/t Au over 2.20 m including 10.40 g/t Au over 1.10 m and;
    • 3.78 g/t Au over 4.40 m
  • Visible gold was observed in OB-21-290W1 at 697.90 m, OB-21-290W2 at 569.60 m, OB-21-290W3 at 741.00 m and OB-21-290W4 at 775.50 m.
• Results represent 3,009 m of directional drill campaign comprising one pilot hole (OB-21-290) and 5 branches, with estimated savings of 1,617 m (35%).
• Drilling to date has highlighted continuity of mineralization down to a vertical depth of over 800 m in this sector where modeled resources are largely within 400 m from surface.
• OB-21-290 and branches returned several relatively broad high-grade Au intercepts confirming the potential for wider mineralized zones in the sector (in excess of average widths of 2.90 m in the current resource) below 400 m where multiple veins are interpreted and with veins intersecting each other.
  • Also highlighted by previously released holes from this area including 11.13 g/t over 10.70 m (OB-21-201), 18.42 g/t over 5.00 m (OB-20-180), 8.35 g/t over 6.00 m (OB-20-124), 6.89 g/t over 21.20 m (OB-20-156), 8.20 g/t over 7.00 m (OB-21-202), 8.87 g/t over 5.00 m (OB-21-187) and 5.77 g/t over 7.10 m (OB-20-156W2)
• 130,000 m drill program underway at O’Brien
  • 126,000 m (253 holes) completed as of May 9, 2022, with results pending for 25,000 m in 52 holes of which 22 holes intersected visible gold.
  • Cash balance of approx. $5.5M as of May 15, 2022

“This second batch of results from directional drilling completed as part of the ongoing program highlight the significant high-grade potential along trend #2. We are particularly impressed that drilling in this sector continues to return relatively broad intercepts below 400 m, highlighting strong vertical and lateral continuity to potentially wider zones around the intersection of multiple mineralized veins. Observed mineralized widths in these areas appear to be meaningfully wider than the average 2.90 m in currently modeled resource areas, in turn significantly enhancing the high-grade nature of the deposit on trend #2.

Overall, results from our ongoing 130,000 m drill program continue to impress with 201 holes published so far including 136 intercepts grading over 5 g/t. We look forward to obtaining additional results from the high-grade trends confirmed east of the old O’Brien mine as we continue to focus on expanding the footprint of the deposit. Results are pending from 52 holes of which 22 have intersected visible gold occurrences. Pending results include approximately 9,100 m (14 holes) from our deep directional drill program aimed at testing some of our most promising deeper targets along trend #1 and #2. Our deep directional drilling continues to remain a key priority with two rigs systematically testing deeper high-grade mineralized structures along trend #1 and #2. We look forward to building momentum with significant news flow in the weeks and months ahead.” Commented Rahul Paul, President and Chief Executive Officer.

Notable drill results

Drilling at O’Brien continues to validate the litho-structural model while highlighting resource growth potential laterally and at depth.

Drilling to date has continued to define and expand almost five high-grade mineralized trends (trend 0, 1, 2, 3, 4), located within a 1,200 m strike length respectively to the east of the old O’Brien Mine. Mineralized trends identified bear similarities with structures previously mined at O’Brien down to a depth of 1,100 m (historical production of 587 koz gold grading 15.25 g/t Au).

Drilling so far has demonstrated continuity of mineralization well below the boundary of defined resources in all the defined trends, which remain open for expansion laterally and at depth. In trend #0, drilling has traced mineralization to a depth of 750 m, while current resources are mostly within the first 240 m. In trend #1, drilling has highlighted continuity of mineralization down to a vertical depth of 950 m, while current resources are mostly limited to a vertical depth of approximately 600 m. In trend #2, drilling has highlighted continuity of mineralization down to a vertical depth of over 800 m, while current resources are mostly within 400 m from surface. In trend #3, drilling has traced mineralization down to 500 m vertical depth from surface. Current resources are mostly confined to within a vertical depth of 240 m. In trend #4, drilling has traced mineralization down to a vertical depth of approximately 330 m.

In addition, the Company has completed an initial 5,700 m exploration program at O’Brien West. In addition to validating geological information from historical drill holes, initial results showcase potential for additional high-grade discoveries in this area. O’Brien West remains open in along strike and at depth, with results indicating strong depth continuity in lithological units identical to those observed along strike to the west, reaffirming the upside potential from approximately 2.5 km of largely untested prospective ground west of the O’Brien Mine along the prolific Larder-Lake-Cadillac break.

Almost all drilling conducted as part of the ongoing campaign has been within a strike length representing only a small portion of the approximately 5.2 km prospective strike that Radisson controls along the Cadillac Break. Given current geological understanding, the ongoing validation of the litho-structural model, the company estimates there is strong potential for additional high-grade gold trends to be discovered along the whole 5.2 km prospective land package on the prolific Larder-Lake Cadillac Break.

126,000 m of drilling completed to date with assays pending for approx. 25,000 m

This release represents approximately 3,000 m of drilling in 6 drill holes. Released results to date (since the commencement of drilling in August 2019) represent approximately 77% of the approximately 130,000 m planned thus far. As of May 15, 2022, the company remains well funded with approximately $5.5 m in cash.

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.
