Osisko Mining Inc. is pleased to announce new results from the ongoing drill program at its 100% owned Windfall Lake gold project located in the Urban Township, Québec. The current 100,000 metre drill program combines definition drilling above the Red Dog intrusion ('Red Dog'), expansion drilling above and below Red Dog and exploration drilling on the greater property area. A total of 12 new drill holes are reported in this release.
Definition drilling near the Caribou Zone has led to a significant new discovery 150 metres below the known Caribou Zone. The new mineralized zone ("Wolf Zone") is defined by drill hole OSK-W-16-710 which intersected 11.8 g/t Au over 6.7 metres (23.62 g/t Au over 6.7 metres uncut) from 562.0m - 568.9m. Additional mineralization was also discovered in the hanging wall and footwall of the Wolf Zone, with assays returning 8.32 g/t over 3.0 metres and 16.2 g/t Au over 2.3 metres respectively. Further drilling will be directed to investigating the dimensions of the Wolf Zone in the coming month. These new intercepts demonstrate the high potential for significant new mineralization near the known Windfall mineral inventory through continued definition and exploratory drilling.
Highlights from additional new drill holes also include: 8.89 g/t Au over 6.9 metres in DDH OBM 16- 701, 18.4 g/t Au over 2.3 metres in DDH OBM-16-703, 16.2 g/t Au over 2.3 metres in DDH OSK-W- 16-710, 16.0 g/t Au over 2.0 metres in DDH OBM-16-697; 11.33 g/t Au over 2.2 metres in DDH OSK-W-16-707, and 8.06 g/t Au over 2.5 metres in DDH OBM-16-698. The new results continue to demonstrate lateral and vertical continuity of high grade gold mineralization in Zone 27 and the Caribou Zone, and also highlight new zones developing between those two major mineralized corridors. Details of the significant new results are outlined in the table below:
(1) For complete drilling results please see http://www.osiskomining.com/.
(2) True widths are estimated at 65-80% of the reported core length interval. See "Quality Control" below.
(3) High grade values cut to 100 g/t Au.
Drill Hole Collar Coordinates and Information:
DDH OBM-16-697 intersected 16.0 g/t Au over 2.0 metres, including 63.5 g/t Au over 0.5 metres in a quartz-tourmaline vein at the contact between a porphyry dyke and felsic volcanics.
DDH OBM-16-698 intersected 8.06 g/t Au over 2.5 metres, including 19.0 g/t Au over 1.0 metre at the upper contact of a porphyry dyke. This interval is located 140 metres to the SE of the Caribou Zone in a sparsely drilled sector. The hanging wall of the Caribou Zone returned 3.62 g/t Au over 2.9 metres. This hole also intersected gold mineralization in the eastern extension of the Caribou N2 Zone 110 metres further east than the known zone, returning 4.49 g/t Au over 3.5 metres.
DDH OBM-16-699 discovered new gold mineralization 90 metres to the NW of the FW3 Zone (below Red Dog) returning 6.63 g/t Au over 2.5 metres (including 21.6 g/t Au over 0.5 metres). Further drilling will follow up in this sparsely drill sector.
DDH OBM-16-701 is located 140 metres to the ENE of the previously interpreted Caribou Zone. The hole intersected a new zone to the SW of Caribou, returning 5.14 g/t Au over 6.1 metres. This hole also intersected the Caribou hanging wall, returning 4.82 g/t Au over 7.0 metres (including 22.4 g/t Au over 1.0 metre) in an altered andesite with a crustiform vein. The hole also intersected the eastern extension of the Caribou N2 zone, returning 8.86 g/t Au over 6.9 metres (including 47.7 g/t Au over 1.0 metre). The hole also intersected 6.68 g/t Au over 2.1 metres at the contact of a porphyry dyke in the eastern extension of Zone 27.
DDH OBM-16-702 tested the shallow portion of the Caribou Zone and returned 3.81 g/t Au over 1.8 metres (including 9.69 g/t Au over 0.7 metres).
DDH OBM-16-703 intersected the interpreted western extension of the FW1 Zone (below Red Dog) and returned 18.4 g/t Au over 2.3 metres (including 38.23 g/t Au over 1.1 m) in a felsic volcanic rock containing pyrite and traces of chalcopyrite.
DDH OBM-16-704 intersected Zone 27 returning 3.55 g/t Au over 4.2 metres. This intercept is located 33 metres below OBM-16-685 (which returned 9.63 g/t Au over 3.3 metres) and confirms continuity of gold mineralization in this zone.
DDH OSK-W-16-705 intersected the new Wolf Zone (also intersected in DDH OSK-W-16-710), returning 4.04 g/t Au over 2.0 metres in an altered mafic volcanic rock.
DDH OSK-W-16-707 intersected the Caribou S2 Zone 190 metres below surface, returning 11.33 g/t Au over 2.2 metres (including 58.6 g/t Au over 0.4 metres) in a porphyry dyke.
DDH OSK-W-16-709 intersected the extension of the Caribou S1 Zone, returning 4.90 g/t Au over 3.7 metres in a sparsely drilled sector.
DDH OSK-W-16-710 confirmed the new Wolf Zone, returning 11.8 g/t Au over 6.7 metres. The Wolf Zone is located between the Caribou S3 and the Caribou N2 Zones. The Wolf Zone correlates with OBM-16-658 which returned 8.90 g/t Au over 8.0 metres, now re-interpreted to be part of this new zone. Additional new mineralization was also discovered in the hanging wall and footwall of the Wolf Zone, returning 8.32 g/t over 3.0 metres and 16.2 g/t Au over 2.3 metres respectively. The Wolf Zone remains undefined by drilling to the east.
