Bonanza Grade Intercept of 421 g/t Au over 3.7 Metres in Lynx 2
(Montréal, May 10, 2017) Osisko Mining Inc. (OSK:TSX, “Osisko” or the “Corporation”) is pleased to announce 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 (“Red Dog”), 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. Significant new analytical results from five drill holes focused on infill and expansion drilling in the Lynx Corridor are reported in the table below.
Highlights from the new results include: 421 g/t Au over 3.7 metres, including 3.74 kilograms/t Au over 0.4 metres containing spectacular visible gold (27.8 g/t Au over 3.7 metres cut to 100g/t) in DDH OSK-W-17-834; 11.7 g/t Au over 7.7 metres in Lynx 4 discovery DDH OSK-17-816; and 10.4 g/t Au over 4.9 metres in DDH OSK-17-802. Maps showing drill hole locations and full analytical results are available at www.osiskomining.com.
|Hole No.||From (m)||To (m)||Interval
Notes: True widths are estimated at 65 – 80% of the reported core length interval. See “Quality Control” below.

OSK-W-17-802 returned 10.4 g/t Au over 4.9 metres including 37.5 g/t Au over 1.0 metre from crustiform veins cross-cutting the Lynx 2 Zone. Mineralization is composed of up to 5% disseminated pyrite, 3% pyrite stringers and up to 2% sphalerite associated to strong grey silica alteration. Visible gold is hosted in a quartz tourmaline vein in the felsic volcanic package. This hole is a 25 metre step-out eastward of drill holes OSK-W-17-825 and OSK-W-17-834 described below.
OSK-W-17-806 intersected Lynx 2 in a strongly sericitized and silicified felsic volcanic. The intercept averaged 3.13 g/t Au over 3.9 metres (including 8.24 g/t Au over 0.9 metres). Mineralization is composed of 3% pyrite stringers. This intercept is located 60 metres under drill hole OSK-W-16-755, which returned 8.12 g/t Au over 2.0 metres (previously released January 11, 2017).
OSK-W-17-816 intersected a new zone averaging 11.7 g/t Au over 7.7 metres including 85.9 g/t Au over 0.3 metres (the “Lynx 4” Zone). Lynx 4 is 170 metres south of Lynx 1. Mineralization consists of up to 15% pyrite, disseminated and stringers, with visible gold grains associated with pyrite clusters.
OSK-W-17-825 intersected 6.71 g/t Au over 2.8 metres (including 21.6 g/t Au over 0.7 metres) in Lynx 1. Mineralization is composed of 8% pyrite at the contact between a fragmental porphyry dike and a strongly silicified rhyolite. This hole is an infill between OSK-W-16-760 (93.3 g/t Au over 9.0 metres uncut) and OSK-W-17-788 (17.0 g/t Au over 12.3 metres) previously released January 11 and April 5, 2017 respectively.
OSK-W-17-834 returned of 421 g/t Au over 3.7 metres (27.8 g/t Au over 3.7 metres cut), including 3.74 kilograms/t Au over 0.4 metres (uncut) in Lynx 2. The intercept contains local spectacular visible gold as patches and fracture fillings in smoky quartz-tourmaline veins hosted in a strongly sericitized and grey silicified rhyolite. This intercept is located 50 metres under OSK-16-760 which returned 95.3 g/t Au over 9.0 metres (previously released January 11, 2017).
The scientific and technical content of this news release has been reviewed, prepared and approved by Mr. Louis Grenier, M.Sc.A., P.Geo. (OGQ 800), 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”).
Quality Control and Reporting Protocols
True width determinations are estimated at 65 – 80% true core lengths. Assay are uncut except where indicated, and calculated intervals are reported over a minimum length of 2 metres using a lower cutoff of 3 g/t Au. All NQ core assays reported were obtained by either 1 kilogram whole rock metallic screen/fire assay or standard 50 gram fire-assaying with AA or gravimetric finish at ALS Laboratories in Val dOr, Québec or Sudbury, Ontario. The 1 kilogram metallic screen assay method is selected by the geologist when samples contain coarse gold or present a higher percentage of pyrite than surrounding intervals. All samples are also analyzed for multi-elements, including silver, using an Aqua Regia-ICP-AES method at ALS laboratories. Drill program design, Quality Assurance/Quality Control and interpretation of results is performed by qualified persons employing a Quality Assurance/Quality Control program consistent with NI 43-101 and industry best practices. Standards and blanks are included with every 20 samples for Quality Assurance/Quality Control purposes by the Corporation as well as the lab. Approximately 5% of sample pulps are sent to secondary laboratories for check assays.
About the Windfall Lake Gold Deposit
The Windfall Lake gold deposit is located between Val-dOr and Chibougamau in the Abitibi region of Québec, Canada. The current mineral resource comprises 2,762,000 tonnes at 8.42 g/t Au (748,000 ounces) in the indicated category and 3,512,000 tonnes at 7.62 g/t Au (860,000 ounces) in the inferred category (sourced from a technical report dated June 10, 2015 entitled “Preliminary Economic Assessment of the Windfall Lake Gold Property, Québec, Canada” with an effective date of April 28, 2015, prepared in accordance with NI 43-101). The Windfall Lake gold deposit is currently one of the highest grade resource-stage gold projects in Canada. The bulk of the mineralization occurs in the Main Zone, a southwest/northeast trending zone of stacked mineralized lenses, measuring approximately 600 metres wide and at least 1,400 metres long. The deposit is well defined from surface to a depth of 500 metres, and 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, with significant potential to extend mineralization up and down-plunge and at depth.
