Osisko Mining Inc. announced new results from the ongoing drill program at its 100% owned Windfall Lake gold project located in Urban Township, Québec. The current 400,000 metre drill program combines definition drilling above the Red Dog intrusion, expansion drilling above and below Red Dog, expansion drilling to the NE of the main deposit, and exploration drilling on the greater deposit and Urban-Barry Project area. Nine drills are currently active directly on the Windfall deposit, with additional drills planned to be added by month end. Including areas outside the main deposit, a total of 12 drills are currently active. Significant new results include: 12.7 g/t Au over 5.4 metres in OSK-W-16-749 and 10.3 g/t Au over 3.0 metres in OSK-W-16-743-W2; 11.0 g/t Au over 2.4 metres and 8.13 g/t Au over 2.6 metres in OSK-W-16-743-W1. Caribou Corridor: Four of the drill holes intersected the CS1 Zone of the Caribou Corridor, expanding it to 360 metres by 200 metres. The CS1 Zone remains open down plunge. OSK-W-16-749 returned 12.7 g/t Au over 5.4 metres hosted in a silicified porphyry dyke containing 2% to 35% pyrite stringers and disseminations. This intercept is located 120 metres to the southwest of previously released OSK-W-16-706 which returned 8.65 g/t Au over 3.0 metres. OSK-W-16-743-W2 intersected 10.3 g/t Au over 3.0 metres in a bleached andesite containing 5% - 20% pyrite stringers and disseminations, expanding the CS1 Zone 120 metres down-dip. OSK-W-16-754 assayed 7.15 g/t Au over 2.1 metres in the strongly silicified and sericitized contact between a porphyry dike and andesite containing 5-20% pyrite stringers with minor visible gold. This hole expands the CS1 Zone 60 metres down-plunge from previously reported OBM-15-564 which returned 5.59 g/t Au over 7.4 metres. The hole also intersected 4.94 g/t Au over 3.0 metres in the FW0 Zone and 3.66 g/t Au over 2.6 metres in the FW0 Footwall Zone, both of which contain mineralization similar in style to that above the Red Dog. OSK-W-16-756 intersected 3.29g/t Au over 2.6 meters and extended the CS1 Zone 60 metres northeast of previously reported OBM-15-564 (5.59 g/t Au over 7.4 meters) and 95 metres above previously reported OSK-W-16-754 (7.15 g/t Au over 2.1 metres). Mineralization comprises 15% pyrite stringers at the contact between a porphyry dike and strongly sericitized andesite. Underdog Corridor: OSK-W-16-743-W1 targeted several parallel zones of the Underdog Corridor and intersected 5.77 g/t Au over 5.2 meters, extending the FW0 Zone by 100 metres southwest of previously reported OBM-15-560 (12.5 g/t Au over 2.0 meters). Mineralization consists of 10% to 30% pyrite stringers in a strongly silicified fragmental porphyry dike. The FW0 Zone has been intersected by eight drill holes to date and now defines an area 210 metres by 290 metres. The hole also intersected the FW2 Zone assaying 8.13 g/t Au over 2.6 metres and extends the zone by 130 metres west of previously reported OSK-W-16-743 (47.0 g/t Au over 2.6 metres; 303.1 g/t Au over 2.6 metres uncut). Gold mineralization is hosted in a silicified porphyry dike containing semi-massive pyrite. The FW2 hanging wall returned 6.77 g/t Au over 2.1 metres in a silicified porphyry dike containing 2-5% pyrite and the FW3 Zone returned 6.29 g/t Au over 2.0 metres at the contact between felsic volcanics with 2-3% pyrite stringers and disseminations.
