Radisson's drilling at O’Brien delivers high-grade gold intercepts

Jul 20, 2020

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

"Results released so far represent only 45% of our fully funded 60,000 m program. With three drill rigs now operating at O’Brien, we look forward to releasing additional updates as we continue to drill test high potential targets over the coming months.” commented Mario Bouchard, President and CEO.

“Drill results continue to showcase significant upside to resources at the high-grade O’Brien project. The majority of current resources are contained within a 1.5 km strike (out of a total strike length of 4.5 km) and 400 m vertical depth in a prolific gold camp where deposits (including the old O’Brien Mine) have been mined to depths well below 1,000 m. 

The depth potential continues to stand-out with additional high-grade results from the lower 36E Zone that demonstrate the continuity of mineralization well below the current resource boundary. All holes drilled as part of this campaign have intersected mineralization within the targeted geological units, with most holes returning high-grade intercepts, often accompanied by visible gold showings. Of note, OB-19-98W2 returned 37.76 g/t Au over 2.00 m approximately 720 m below the surface, and 60 m west and 100 m above previously released intercept of 66.71 g/t Au over 4.70 m. Drilling continues to demonstrate strong continuity of high-grade mineralization down to 950 m, and within what appears to be a mineralized trend bearing similarities to that historically mined at the Old O’Brien Mine. Mineralization remains open for expansion laterally and at depth, with additional drilling underway to expand mineralization to the west in a largely untested area below the resource boundary.  

In addition, shallower drilling aimed at resource expansion and conversion has continued to deliver high-grade results in the upper 400 m of the deposit. In particular, drill hole OB-20-127 returned 3.07 g/t Au over 32.20 m close to the western boundary of currently defined resources, including four high-grade sub-intercepts (5.20 g/t Au over 2.00 m, 7.12 g/t Au over 2.70 m, 6.52 g/t Au over 2.30 m and 8.04 g/t Au over 3.20 m)  within and outside the boundary of currently modeled inferred resources. Our team is currently developing additional drill targets on this part of the deposit which remains open laterally for resource expansion. Another shallow hole, OB-20-135, drilled 300 m east of this area returned 18.15 g/t Au over 4.40 m at the fringe of an indicated resource block, confirming and expanding mineralization 15 m east of a historical intercept of 125.31 g/t Au over 3.05 m.

Our exploration program is focused on three key opportunities for resource expansion: the western extension of the first mineralized trend defined on Lower 36E, the second mineralized trend recently highlighted approximately 300 m east of the first trend and on resource expansion opportunities at shallower depths east and west of these two trends.
