Drill results from Radisson Mining’s (TSXV: RDS; US-OTC: RMRDF) wholly owned O’Brien project in Quebec include high-grade intercepts from areas below current resource boundaries and from zones around the existing deposit.
Drill highlights include 32 metres of 3.07 grams gold per tonne from the Upper 36E area at a vertical depth of 430 metres. The hole was drilled near the western boundary of the deposit and returned four high-grade sub-intercepts within the 32-metre interval within and outside of the resource boundaries.
Additional high-grade hits from Upper 36E include 4 metres of 18.15 grams gold at 190 vertical metres from an area 300 metres east of the main mineralized trend at the 36E zone.
Radisson’s geology team is generating additional drill targets in the Upper 36E area, which is open on strike.
Deeper drilling within the Lower 36E zone hit 2 metres of 37.76 grams gold at a depth of 720 metres, 60 metres west of a prior intercept. According to the company, the result suggests strong continuity of high-grade mineralization down to a depth of 950 metres, within a mineralized trend similar to past-producing areas at the O’Brien mine. This deeper zone is open on strike and at depth with followup drilling underway, testing western extensions of this mineralization in an underexplored area below existing resources.
“Drill results continue to showcase significant upside to resources at the high-grade O’Brien project,” Mario
“Results released so far represent only approximately 45% of our fully funded 60,000-metre program, ” Mario Bouchard, the company’s chief executive officer, said in a news release. “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.”
Bouchard added that the majority of the resources are contained over a strike length of 1.5 km, within a 4.5-km long trend, and extend down to a depth of 400 metres.
To date, Radisson has drilled 34,230 metres in 72 holes as part of the company’s ongoing 60,000-metre drill program. Assays are pending for 18 drill holes.
Resources at the project include 950,000 indicated tonnes grading 9.48 grams gold, containing 289,000 oz. gold, with another 617,000 inferred tonnes at 7.31 grams gold, for 145,000 oz. gold. The resources are derived using a 5 gram gold per tonne cutoff grade.
The past-producing O’Brien project is within the Bousquet-Cadillac mining camp in Quebec’s Larder Lake-Cadillac break. The former O’Brien mine at the site generated 1.2 million tonnes at 15.25 grams gold between 1926 and 1957.
