Radisson Mining Resources Inc. reports multiple high-grade intercepts

Key highlights

• Significant intercepts from exploration drilling along trend #0 (approximately 300 m gap between the old O'Brien Mine and currently modeled resources along trend #1)
  • 59.79 g/t over 3.00 m including 173.50 g/t over 1.00 m (OB-21-235)
  • 9.43 g/t over 3.00 m including 16.30 g/t over 1.00 m (OB-21-231)
  • 13.55 g/t over 2.00 m (vertical depth of 620 m) including 53.00 g/t over 0.50 m (OB-21-247), representing the deepest high-grade intercept in this sector from the ongoing drill program.
  • 8.71 g/t over 2.05 m including 17.00 g/t over 1.05 m (OB-21-249)
• Modeled resources in the area are mostly limited to within 240 m of surface. New and previously released results (including 92.89 g/t over 2.60 m, 47.10 g/t over 2.60 m, 10.87 g/t Au over 3.15 m and 14.90 g/t over 8.20 m) demonstrate continuity of high-grade mineralization in the area down to a vertical depth of 620 m and up to 140 m west of currently modeled resources along trend #1.
• Results are pending for approximately 9 additional holes drilled in this sector, with visible gold showings in 5 of those holes.
  • Of particular interest are the results from a deep directional drilling program, comprising one pilot hole and 7 branches, to test the depth extent of mineralization in this sector down to more than 800 m from surface (up to 200 m below the extent of previous drilling). All of these holes intersected targeted structures including visible gold occurrences in four holes.
• 130,000 m drill program underway at O'Brien.
  • 119,800 m (231 holes) completed as of February 13, 2022 with results pending for 25,500 m in 55 holes of which 24 holes intersected visible gold.
  • Cash balance of approx. $9.0M as of February 15, 2022.
    

"Results from the ongoing program highlight the significant high-grade potential along trend #0, which represents the approximately 300 m gap between current resources in trend #1 and historically mined zones at the old O'Brien Mine. This area was never meaningfully drilled prior to the current program, as a result of which its resource contribution is limited and mostly within 240 m from surface. This area became a key focus of our drill program last year, with drill results to date demonstrating the continuity of high-grade mineralization down to more than 600 m depth. Drill results to date from this sector have been very impressive, with 26 holes published, including 14 intercepts returning grades of over 5 g/t and 6 intercepts returning grades of over 10 g/t. We look forward to obtaining results for an additional 9 holes, of which 5 intersected visible gold. This includes results from our first directional drill program comprising one pilot hole and seven branches, drilled to test the depth extent of mineralization down to 800 m or up to 200 m below the limits of previous drilling.

Overall, results from our ongoing 130,000 m drill program continue to impress with 176 holes published so far including 130 intercepts grading over 5 g/t and 55 intercepts grading over 10 g/t. In addition, results are pending from 55 holes to the east of the O'Brien Mine of which 24 holes have visible gold occurrences. We are also currently drilling some of our most promising deep targets below previously encountered mineralization in trend #1 and #2. We look forward to building momentum with significant news flow in the weeks and months ahead as these results become available," commented Rahul Paul, President and Chief Executive Officer.

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, located within a 1,200 m strike 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 grading 15.25 g/t).

Drilling so far has demonstrated continuity of mineralization well below the boundary of defined resources in all defined trends, which remain open for expansion laterally and at depth. In trend #0, drilling has traced mineralization to a depth of 620 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 all direction, 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 more than 5.2 km of 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.

119,800 m of drilling completed to date with assays pending for approx. 25,500 m

This release represents approximately 8,130 m of drilling in 16 drill holes. Released results to date (since the commencement of drilling in August 2019) represent approximately 72% of the approximately 130,000 m planned thus far.¹ As of February 15, 2022, the company remains well funded with approximately $9.0 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.
