Radisson intersects 24.22 g/t Au over 3.00 m and 19.63 g/t Au over 3.40 m, up to 280 m below the resource boundary along the first high-grade trend at the O’Brien project






Radisson Mining Resources Inc. (TSX-V: RDS) (OTC: RMRDF) 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.

1. VG denotes the presence of visible gold
2. Core length or down hole width. True widths are estimated at 70% to 80% of down hole width. To the extent possible, primary intercepts reflect minimum mining width (1.5 m true width) consistent with assumptions used in the 2019 resource estimate.
3. Assay grades shown uncapped. A capping factor of 60 g/t Au was used in the 2019 resource estimate
4. Table includes only intercepts that meet 5 g/t Au cut-off and minimum mining width constraints used in the 2019 MRE. For a full listing of drill results from current drilling program click here.


Resource expansion potential at depth along mineralized trend #1 (300 m east of the old O’Brien Mine)


Hole OB-20-174w1b returned 24.22 g/t Au over 3.00 m core length (see figure 3 for Au grade distribution) at a vertical depth of 930 m approximately 280 m below the boundary of resources. In addition, OB-20-181 returned multiple high-grade intercepts including 13.74 g/t Au over 1.70 m core length (vertical depth of 785 m) and 19.63 g/t Au over 3.40 m (vertical depth of 820 m), the high-grade intercepts were respectively obtained approximately 120 m and 170 m below the resource boundary.


OB-20-174w1b is a wedge off pilot hole OB-20-174 which also intersected multiple lower-grade mineralized zones approximately 30 m west of the above intercept. OB-20-174 and OB-20-174W1b are the deepest holes drilled since the beginning of the program to test the extension of mineralized trend #1.


The high-grade intercepts obtained in hole OB-20-174w1b and OB-20-181 appear to have been obtained in the same geological units. These intercepts along with other previously released intercepts including 66.71 g/t Au over 4.70 m (OB-19-92W2b), 37.76 g/t Au over 2.00 m (OB-19-98W2), 23.57 g/t Au over 2.60 m (OB-19-107), 45.33 g/t Au over 2.20 m (OB-20-148W1) and 110.97 g/t Au over 2.50 m (OB-20-167) demonstrate continuity of high grade mineralization down to a vertical depth of 950 m and up to 350 m below currently defined resources on trend #1.


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 three high-grade mineralized trends, located approximately 300 m, 600 m and 900 m 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 three trends, which remain open for expansion laterally and at depth. In trend #1, drilling has highlighted continuity of mineralization down to a vertical depth of 950 m, approximately 350 m below the boundary of resources that are limited to a vertical depth of 600 m. In trend #2, drilling has highlighted continuity of mineralization down to a vertical depth of 770 m, approximately 300 m below the boundary of resources that 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 between surface and 240 m vertical depth.


Almost all drilling conducted as part of the ongoing campaign has been within a strike length of approximately 1 km to the east of the old O’Brien mine, representing only a small portion of more than 5.2 km of prospective strike that Radisson controls along the Cadillac Break.


60,499 m of drilling completed to date with assays pending for approx. 11,360 m


This release represents approximately 3,196 m of drilling. Released results to date (since the commencement of drilling in August 2019) represent approximately 39% of the 130,000 m envisioned to be complete by the end of 2021. As of January 31, 2021, the company remains well funded with approximately $14.5 m in cash.

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 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. Samples 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 program.
