Osisko Intercepts 6.14 g/t Au Over 14.4 Metres At Black Dog
(Montréal, December 6, 2016). Osisko Mining Inc. (OSK:TSX, “Osisko” or the “Corporation”) is pleased to announce initial drill results from its 100% owned Black Dog gold project located in Barry Township, Québec. The project is situated 15 kilometres SW of its flagship Windfall Lake Gold Deposit. Drilling is targeting geophysical conductors identified with an airborne electromagnetic (EM) survey completed earlier in the year by Osisko that coincide with a 600 x 800 metre circular magnetic anomaly. The geophysical anomalies sit atop a zone of pervasive and/or brecciated quartz-tourmaline-sulfide alteration that has been the object of historical shallow drilling.
DDH OSK-BD-16-002 was collared 150 metres to the east of an outcropping alteration zone (dubbed “Tourmaline Hill”). This new hole intersected 6.14 g/t Au and 34.1 g/t Ag over 14.4 metres, including 15.6 g/t Au and 93.5 g/t Ag over 2.8 metres in a mineralized tourmaline breccia containing 2-15% coarse pyrite and 10% chalcopyrite. This intersection is part of a wider intercept that averaged 3.42 g/t Au and 23.2 g/t Ag over the entire intersected length of 32.1 metres. Significant results from the two drill holes are presented in the table below. DDH OSK-BD-16-001 was collared 600 metres to the SW of OSK-BD-16-002 and intersected 5.76 g/t Au and 34.8 g/t Ag over 0.9 metres in a tourmaline breccia.
Further drilling is currently in progress and is directed at determining the extent and continuity of the new mineralization discovered at Black Dog.

The scientific and technical content of this news 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 and the Black Dog Gold Project, who is a “Qualified Person” as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”).
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 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 Black Dog Project
The Black Dog Project is located approximately 90 kilometres east of Lebel sur Quevillon, 14 kilometres southwest of, and along the same geological trend as, Osiskos Windfall Lake project. Three zones have been defined by historical work on the property including the Nubar Zone (with estimated resources of 564,000 tonnes at 6.2 g/t Au, based on historical estimates that have not been prepared in accordance with NI 43-101, the Tourmaline Hill Zone, and the Barry-Souart Zone. These three zones are located along a 5 kilometre length of the same geological structure. See below under the heading “Disclosure of Historical Estimates”.
Disclosure of Historical Estimates
In 1950, Nubar Mines Ltd. sunk a 44 metre deep shaft and drove 135 metres of drifts and crosscuts. Several exploration surveys were then completed by other companies (Glenelm Developers Limited, Goldmaster Mines Ltd., Shell Canada Limited, Tut Explorations, Société de développement de la Baie-Jaimes (SDBG) and Oasis Resources Inc.). Between 1985 and 1990, Oasis Resources Inc. completed 152 drill holes, followed with an estimated resource calculation of 564,000 tonnes at 6.2 g/t Au. These resource estimates are of a historical nature and do not comply with NI 43-101. However, the resource estimate may be relevant because the Black Dog property encompasses the same geological trend that the Nubar Zone occupies and, to the best of the knowledge of Mr. Jean-Phillipe Desrochers, there has been no material change with respect to the metallic minerals within the original resource estimation area (and region) that would affect the estimation parameters since 1985. Further drilling would be required to upgrade or verity the historical resource estimate as current mineral resources or reserves. Osisko is unaware of the existence of any technical report prepared in connection with the scientific and technical information in this news release. A Qualified Person (within the meaning of NI 43-101) has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves. Osisko is not treating the historical estimate as current mineral resources or mineral reserves. Further, there have not been any mineral resources calculated on the Black Dog property recently.
