GOLD: Osisko enjoys more bonanza grades at Windfall



QUEBEC – Montreal’s Osisko Mining reports that it has again intersected bonanza grades during drilling at its Windfall Lake gold property in Urban Township. The company has been rewarded with an intersection of 65 g/t Au over 5.7 metres (148 g/t uncut) at a depth of 200 metres.

Osisko has been drilling every 200 metres outwards from the previously defined Windfall resource. The bonanza grade was from the first three step out lines extending 600 metres from the main deposit. The program is testing a linear magnetic depression that is interpreted to be related to a magnetite destructive silica-sericite alteration corridor associated with the Windfall intrusive system. The linear structure currently being investigated with the step out drilling is parallel to the Windfall deposit and extends for an additional 2,600 metres northeast of the deposit.

So far, Windfall contains 2.76 million measured and indicated tonnes averaging 8.42 g/t Au and containing 750,000 oz of gold plus 3.51 million inferred tonnes at 7.62 g/t and containing 860,000 oz.

A thorough discussion of the Windfall geology is available in the Windfall presentation at the Osisko website.
