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.
“We are very excited to report results from our exploration program to the west of the old O’Brien Mine, an area with very limited drilling located 900 m from current resources boundary. We view initial results as very significant in that they demonstrate high grade potential in the area from mineralized zones bearing similarities to those observed in the resource area and the old O’Brien Mine. 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 strike west of the O’Brien Mine along the prolific Larder-Lake-Cadillac break.
In addition to validating geological information from historical drill holes, initial results showcase potential for additional high-grade discoveries in this area, most notably with hole OB-21-250 intersecting 38.34 g/t over 2.00 m within only 215 m of surface and OB-21-186 intersecting 7.24 g/t over 3.20 m, approximately 85 m further west. Drilling also highlighted the potential for good depth continuity down to 780 m with deeper holes intersecting mineralized structures.
With initial drilling significantly exceeding our expectations, our team will be working on generating new high-priority exploration targets as we look forward to systematically stepping out with the aim of extending the footprint of mineralization along the 2.5 km of prospective strike at O’Brien West. In addition, results are pending from 28,300 m of drilling in 62 holes to the east of the O’Brien Mine, of which 32 holes have visible gold occurrences. We are also currently drilling high priority deep targets below previously encountered mineralization in trend #1 and #2. We expect significant news flow in the weeks and months ahead as these results become available.” commented Rahul Paul, President and Chief Executive Officer.

Exploration drilling on O’Brien west
Results from an initial 5,700 m exploration campaign west of the old O’Brien mine demonstrate the high-grade potential along the largely untested 2.5 km strike length to our western claim boundary, an area that does not currently contribute to resources. This campaign was successful at validating historical drill data, enhancing our geological interpretation of the sector and confirming the expansion potential along strike and at depth. Results obtained to date suggest the potential to discover new high-grade enrichment vectors and in turn meaningfully drive resource expansion in the future.
These encouraging results also appear to confirm the high-grade potential in the area, most notably with drill hole OB-21-250 intersecting 38.34 g/t over 2.00 m. While some drill holes returned lower gold assay values, initial drilling has traced mineralized zones down to 780 m vertical depth. This includes OB-21-254 which intersected mineralized structures with visible gold occurrences below the above intercept and hole OB-21-190 which suggests that mineralized structures likely extend to greater depths.
Lithological units observed in the drill holes appear identical to those observed in the New Alger area. In addition, all holes intersected significant mineralized zones bearing similarities to those observed on the resource area and the old O’Brien mine, including quartz veins within a halo altered in biotite and mineralized in arsenopyrite.
The company is currently integrating the data into the litho-structural model to generate new high-priority exploration targets and to better define the geometry of mineralized zones and gold-bearing structures.
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 four high-grade mineralized trends, located approximately 300 m, 600 m, 900 m and 1,200 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, 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.
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. Given current geological understanding, the ongoing validation of the litho structural model, the company estimates there is strong exploration for additional high-grade gold trends along the whole 5.2 km prospective land package on the prolific Larder-Lake Cadillac Break.
119,000 m of drilling completed to date with assays pending for approx. 28,300 m
This release represents approximately 5,700 m of drilling in 12 drill holes. Released results to date (since the commencement of drilling in August 2019) represent approximately 67% of the 130,000 m planned thus far. As of January 15th, 2022, the company remains well funded with approximately $10.5 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. 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 program.
