QUEBEC – Osisko Mining of Toronto continues drilling at its 100% Windfall gold project in Urban Twp, and once again is rewarded with bonanza grades. Hole 17-134;5 returned 86.7 g/t gold over 4.3 metres. Hole 17-1334 returned 32.7 g/t over 2.5 metres and 29.6 g/t over 2.9 metres.

Other holes drilled as part of last year’s 800,000 drilling program returned extremely high grades as well: 48.6 g/t over 2.0 metres; 32.7 g/t over 2.8 metres; 41.5 g/t over 2.0 metres and 24.8 g/t over 2.4 metres; 10.0 g/t over 8.0 metres; 11.1 g/t over 6.9 metres; 29.2 g/t over 2.2 metres; 11.6 g/t over 5.4 metres; 25.2 g/t over 2.0 metres; and 20.5 g/t over 2.3 metres.

Osisko has also discovered a new zone called Underdog southwest of the main Windfall Lake deposit. New mineralization was also discovered between the Mallard zone and zone 27 and near the surface west of the main deposit.

The bulk of the mineralization occurs in the main zone, a southwest-northeast trending area of stacked lenses, measuring approximately 600 metres wide and at least 1,400 metres long. The deposit remains open along strike and at depth. Mineralization has been identified only 30 metres from surface in some areas and as deep as 870 metres in others, says Osisko, with significant potential to extend mineralization up and down-plunge and at depth.
