Drilling on Radisson Mining Resources’ (TSXV: RDS; US-OTC; RMRDF) 100%-owned flagship O’Brien gold project in Quebec continues to hit high-grade mineralisation below the current resource. Radisson said the drilling campaign has continued to define and expand three high-grade mineralised trends, located approximately 300, 600, and 900 metres, respectively, to the east of the past-producing O’Brien mine. The mine produced 587,121 oz. of gold between 1926 and 1957 and 10,852 oz. from 1974 to 1981. Highlights include drillhole OB-20-174W1b, which intersected 3 metres grading 24.22 grams gold per tonne starting from 1,017 metres, including 1 metre of 34.10 grams gold. The hole was drilled approximately 280 metres below the resource boundary and as a wedge off pilot hole OB-20-174, a previously reported drill hole 30 metres to the west.
