MONTREAL, QUEBEC--(Marketwired - Nov. 23, 2016) - Osisko Mining Inc. (TSX:OSK) ("Osisko" or the "Corporation") is pleased to announce new results from the Fox discovery, located 3.7 kilometres NW of the Windfall Lake Gold Deposit. The exploration drill program at Fox is part of the ongoing 150,000 metre drill program at Osisko's 100% owned Windfall Lake gold project.
Significant new results from the exploration drilling at Fox include: 27.6 g/t Au over 3.1 metres in DDH OSK-U-16-734; 8.04 g/t Au over 3.0 metres in DDH OSK-U-16-732; 6.78 g/t Au over 2.0 metres in DDH OSK-U-16-731; and 5.14 g/t Au over 2.1 metres in DDH OSK-U-16-736.
The Fox discovery was made with DDH OSX-W-16-717 (which returned 3.22 g/t Au over 11.6 metres, see Osisko press release dated August 29, 2016). The discovery underscores the strong potential that exists for new gold mineralization on the Urban-Barry property, particularly in areas proximal to the expanding Windfall gold deposit. Additional drilling is planned to follow up on these new results and to test lateral extensions of the mineralization. Significant results from four new exploration holes are presented in the table below.

Drill Hole Collar Coordinates and Information
The Fox Zone mineralization occurs within a zone of strong texturally-destructive sericite and silica alteration in bleached andesitic volcanics containing pyrite stringers. In the area of the discovery, the gold mineralization is cross-cut by a post-mineral porphyry dyke and mineralization occurs both in the hanging wall and the footwall of the dyke. The mineralized zones at Fox are very similar to those seen peripheral to high grade gold zones at the nearby Windfall gold deposit.
DDH OSK-U-16-732 intersected shallow mineralization 100 metres to the southeast of the Fox discovery hole OSX-W-16-717, returning 8.04 g/t Au over 3.0 metres in altered andesite containing minor pyrite.
DDH OSK-U-16-734 intersected 27.6 g/t Au over 3.1 metres in a series of laminated quartz-tourmaline veins containing visible gold located 180 metres to the northwest of the Fox Zone.
DDH OSK-U-16-736 intersected the Fox Zone 100 metres to the southwest and 100 metres deeper than the discovery intersection in DDH OSX-W-16-717. The intersection returned 5.14 g/t Au over 2.1 metres in a strongly sericitized andesite with pyrite stringers.
DDH OSK-U-16-738 returned 2.58 g/t Au over 3.9 metres from the hanging wall of a porphyry dyke, in a moderately bleached andesite with pyrite stringers.
Exploration DDH's OSX-W-16-716, -721, -723, -725; and OSK-U-16-729, -730, -733 returned no significant results.

The scientific and technical content of this press release has been reviewed, prepared and approved by Mr. Jean-Philippe Desrochers, Ph.D., P.Geo. 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").
True widths of the new exploration intercepts reported in this press release have yet to be determined. Additional drilling is planned for the immediate area which will enable the true width determination. Assays are uncut except where indicated. All NQ core assays reported were obtained by either 1 kg whole rock metallic screen/fire assay or standard 50 gram fire-assaying with AA or gravimetric finish at ALS Laboratories in Val d'Or, Québec or Sudbury, Ontario. The 1 kg 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 analysed 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 QA/QC program consistent with NI 43-101 and industry best practices. Standards and blanks are included with every 20 samples for QA/QC 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-d'Or 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.
