Osisko Mining announced a new discovery from the ongoing exploration drill program on its 100% owned Urban-Barry Project located in Urban Township, Québec.
The exploration drill program currently involves one drill and is part of the ongoing 100,000 metre drill program at Osisko’s Windfall Lake gold project.
The discovery was made in DDH OSX-W-16-717, which returned an average of 3.22 g/t Au over 11.6 metres. DDH OSX-W-16-717 is located approximately 3.7 kilometres west – northwest of the main Windfall deposit, and lies approximately 1.4 kilometres northwest of exploration hole OBX-16-666 (183.5 g/t Au over 0.3 metres, see Osisko press release dated June 3, 2016). DDH OSX-W-16-717 is part of a fence of holes currently testing the westerly strike of the Windfall Deposit geological trend. A number of target styles are being investigated along this fence, including geophysical anomalies and as follow-up to earlier identified gold-in-till anomalies.
The new drill hole underscores the strong potential for new gold mineralization on the Urban-Barry Project, which has historically seen limited exploration work.
OSX-W-16-717 targeted the contact between a magnetic high and low, 3.7 km to the WNW of the Main Zone at Windfall. The gold mineralization occurs within a zone of strong texturally-destructive sericite and silica alteration in andesite volcanics containing 2-3% pyrite stringers, with tourmaline, fine grained pyrite disseminations and zones of silica-filled brecciated stringers cross-cutting the interval. The mineralization is very similar to that seen at the nearby Windfall gold deposit.

Senior Project Manager of the Windfall Lake gold project, who is a "Qualified Person" as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101").
