Osisko confirms deep high grade zone at Windfall

Osisko Mining (TSX: OSK) has confirmed that a deep discovery it made at its Windfall Lake gold deposit in Quebec over the summer is the real deal, after producing more high grade intercepts from the new zone it’s calling Triple 8. The company started drilling two deep exploration holes in May to test the potential for depth extensions of the Lynx and Underdog mineralized zones and to investigate the intrusion related geological model it has for the Windfall deposit. The primary targets of the two drill holes were in the outer shell of a porphyry intrusion at depths of around 2,500 metres from surface. The first hole it reported on July 11 to test the potential for depth extensions of the Underdog zone – OSK-W-18-1603 – returned 20.4 grams gold per tonne over 28.3 metres from 1,491.3 metres downhole, including a 10-metre interval grading 44.5 grams gold from 1,501 metres downhole.
