Radisson hits high grade at O'Brien between Rouyn and Val D'Or

Oct 13, 2020

Radisson Mining Resources has hit significant high-grade gold intercepts from the ongoing 60,000 m exploration drill program at its O’Brien gold project located along the Larder-Lake-Cadillac Break, halfway between Rouyn-Noranda and Val-d’Or.

“We are very pleased with results from our ongoing drill program that continue to validate our litho-structural model and highlight the significant resource upside at O’Brien. The team has continued to do a commendable job with targeting efforts. With results released so far representing only 60% of our allocated program we look forward to regular exploration updates over the balance of 2020 and into 2021.” said Mario Bouchard, Chief Executive Officer

Shallow high-grade intercepts suggest an opportunity to expand resources in the gap between the old O’Brien mine and the upper part of the first high-grade trend

  • Hole OB-20-153 intersected multiple mineralized intercepts outside defined resources approximately halfway between the first mineralized trend and the old O’Brien Mine, including; 
    • 92.89 g/t Au over 2.60 m (vertical depth of 230 m);
    • 47.10 g/t over 2.50 m (vertical depth of 150 m),
    • Both intercepts were obtained outside current resources west of the first mineralized trend along with visible gold showings
  • These intercepts were obtained above and to the east/west of historical high-grade intercepts of 43.37 g/t Au over 1.31 m and 124.57 g/t over 0.82 m, all of which are currently excluded from the 2019 resource estimate
  • Assays are pending for hole OB-20-168 which intersected visible gold in two sections, 295 m and 330 m respectively below hole OB-20-153 and west of current resources (See Visible Gold in hole OB-20-168 and OB-20-153)
  • OB-20-153 along with previously released and historical high-grade intercepts highlights an opportunity for significant resource growth in gap between the old O’Brien mine and currently defined resources in the first mineralized trend.

Deeper drilling highlights potential for resource growth in the first mineralized trend both to the east and west, below the boundary of currently defined resources 

  • Hole OB-20-148W1 returned 45.33 g/t Au over 2.20 m core length (vertical depth of 700 m) immediately below and at western boundary of current resources within the first mineralized trend. 
    • The intercept was obtained more than 125 m west of other high-grade intercepts including 16.76 g/t over 4.00 m37.76 g/t over 2.00 m and 66.71 g/t over 4.70 m.
    • In addition, OB-20-148 intersected 5.47 g/t over 2.00 m, approximately 150 m below OB-20-148W1.
    • Results highlight the potential to expand mineralization to the west towards the old O’Brien Mine
  • Assays are also pending for OB-20-164, OB-20-167 and OB-20-170, all of which intersected visible gold in mineralized structures, close to historical intercepts of 1920.00 g/t Au over 0.21 m and 101.31 g/t over 0.61 m outside current resources on the eastern portion of the first mineralized trend. (See visible gold in hole OB-20-164OB-20-167 and OB-20-170).
  • Current resources in the area are limited to a vertical depth of 600 m and drilling to date has demonstrated continuity down a depth of approximately 950 m
    • Within an area extending approximately 300 m laterally and 350 m vertically below the resource boundary.
    • Mineralization is open for expansion laterally and at depth below 950 m.

Drilling at O’Brien continues to validate 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)
  • Latest results demonstrate lateral expansion of first mineralized trend to the east and west. Results so far have traced mineralization in the first high-grade trend down to 950 m (approximately 350 m below the resource boundary). Mineralization remains open for expansion at depth as well as laterally to the east and west.
  • 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 km of prospective strike that Radisson controls along the Cadillac Break.

52,500 m of drilling completed to date with assays pending for approx. 16,500 m

  • This release represents approximately 2,729 m of drilling.
  • Released results to date (since the commencement of drilling in August 2019) represent only 60% of the total planned 60,000 m program.
  • The company is funded to expand the program to over 75,000 m.
