Osisko Metals Incorporated (the "Company" or "Osisko Metals") (TSX VENTURE:OM)(FRANKFURT:0B5) is pleased to announce that drilling at the Mount Fronsac project is underway. This maiden drill program is within the previously announced 50,000-metre program planned for the Bathurst Mining Camp ("BMC") that also includes the Gilmour South program (see news releases dated September 11 and October 19, 2017).

Mount Fronsac is one of the most recent discoveries in the BMC and the unclassified historical resource is listed in the New Brunswick Mineral Occurrence file ("NBMO") as hosting 1,260,000 tonnes grading 7.65% zinc, 2.18% lead and 40.3 g/t silver. The objective of the drill program is to increase and upgrade the historical resource to comply with NI43-101 standards. The first phase of drilling will include 25 holes with intercepts spaced at 50 to 100m apart for a total of 10,000m.

Jeff Hussey, President and CEO of Osisko Metals, commented: "The Mount Fronsac project remains largely unexplored. We strongly believe the property offers an excellent potential for resource expansion in the BMC. This is the second of three projects targeted for drilling this fall and will provide steady news flow into 2018."

About Mount Fronsac

The relatively high-grade Mount Fronsac deposit is hosted within 14 million tonnes of low-grade, pyritic semi-massive to massive sulfides that occur in an envelope of favorable alteration (quartz-sericite ± chlorite schist). The amount of lower grade sulphide mineralization is indicative of a significant mineralizing system which offers potential for additional high grade resources.

The higher-grade portion of the deposit has a north-south strike length of 525 metres and a down dip length of 600 metres. Thickness varies from 2 metres up to a maximum of 20 metres. The host rocks at Mount Fronsac North are contemporaneous and similar to the Brunswick Horizon in the BMC, which hosted the world-class former Brunswick No. 12 mine.

The Osisko Metals claim groups in the Mt. Fronsac area also contain several kilometres of favorably altered (variably sulphidic with quartz-sericite ± chlorite) Brunswick Horizon host rocks. There is potential for structural thickening in the area based on the regional interpretation of fold repetitions and faulting.
