An updated estimate for Radisson Mining Resources Inc.'s O'Brien gold project in Quebec increased gold contained in the indicated category by 95% to 233,491 ounces from 119,819 ounces.
The project hosts indicated resources of 1.1 million tonnes grading 6.45 g/t of gold and inferred resources of 1.2 million tonnes grading 5.22 g/t of gold for 194,084 ounces.
The estimate uses a cutoff of 3.5 g/t of gold and incorporates 29,787 meters of drilling completed in 2016 and 2017, according to a March 20 release.
Radisson Mining said the O'Brien deposit remains open at depth below 600 meters and only part of the Vintage zone was included in the update.
The company has completed approximately 5,000 meters of drilling at the Vintage zone since the resource cutoff date, and ongoing drilling is focused on discovering new mineralization at Vintage and expanding resources.
