Radisson reports high grade gold intercepts including 34.71 g/t Au over 3.90 m and 7.55 g/t Au over 10.50 m from resource expansion drilling along trend #1 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.


Key highlights


  • Significant intercepts from resource expansion drilling along trend #1,
    • 34.71 g/t over 3.90 m including 127.00 g/t over 1.00 m (OB-21-216W1)
    • 7.55 g/t over 10.50 m including 10.46 g/t over 6.00 m (OB-21-240)
    • 17.56 g/t over 2.00 m including 34.80 g/t over 1.00 m; and 8.22 g/t over 2.00 m including 14.70 g/t over 1.10 m (OB-21-226)
    • 13.23 g/t over 2.00 m including 32.90 g/t over 0.80 m (OB-21-215)
    • 9.25 g/t over 2.00 m including 11.35 g/t over 1.00 m; and 10.02 g/t over 2.30 m including 14.70 g/t over 1.30 m (OB-21-217)
  • New and previously released high-grade intercepts confirm and support resource expansion potential down to 950 m vertical depth along trend #1
  • 130,000 m drill program underway at O’Brien
    • 99,100 completed thus far with results pending for 23,840 m
    • Cash balance of approx. $8.5M


Drill results continue to validate our lithostructural model while demonstrating significant resource growth potential at the high-grade O’Brien project. Drilling thus far has suggested the potential to at least double the depth extent of resources along three high-grade trends within an approx. 1 km strike to the east of the old O’Brien Mine.


Several high-grade gold intercepts from recent drilling along trend #1, including 34.71 g/t over 3.90 m (OB-21-216W1) and 17.56 g/t over 2.00 m (OB-21-226) intersected mineralized structures outside defined resource blocks, confirming the potential for resource growth along trend #1, laterally and at depth. In addition, drilling intersected 7.55 g/t over 10.50 m (OB-21-240), confirming and potentially expanding some of the deepest inferred resources along this trend.


The majority of our work program thus far has been focused within a 1 km along strike to the east of the historic O’Brien Mine, we believe there is significantly more upside to be unlocked from a prospective land package that includes more than 5 km of strike length along the prolific Cadillac Break. Results so far, all support our theory of discovering and expanding additional high-grade mineralized trends as we step out systematically further along strike and deeper beyond the limits of drilling to date.” commented Rahul Paul, President and Chief Executive Officer.

  1. VG denotes the presence of visible gold
  2. True widths estimated at 70%to 80% of core length. Unless otherwise relevant, primary intercepts reflect minimum mining width (1.50 m true width) at a 5.00 g/t cut-off grade consistent with assumptions used in the 2019 MRE.
  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 high-grade trend #1 (300 m east of the old O’Brien Mine)


Hole OB-21-216W1 returned 34.71 g/t Au over 3.90 m core length (see figure 1 for Au grade distribution) at a vertical depth of 720 m approximately 60 m below current resources boundary. In addition, OB-21-240 returned 7.55 g/t Au over 10.50 m confirming and possibly expanding some of the deepest inferred resources along trend #1. In addition, OB-20-171, OB-21-217 and OB-21-226 returned multiple high-grade intercepts outside current resources both along and outside of targeted zones.


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), 110.97 g/t Au over 2.50 m (OB-20-167), 24.22 g/t Au over 3.00 m (OB-20-174w1b) and 19.63 g/t Au over 3.40 m (OB-20-181) 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, 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.


99,100 m of drilling completed to date with assays pending for approx. 23,840 m


This release represents approximately 7,200 m of drilling in 9 drill holes. Released results to date (since the commencement of drilling in August 2019) represent approximately 58% of the 130,000 m planned thus far. As of October 15, 2021, the company remains well funded with approximately $8.5 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 (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. 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.
