OSISKO METALS INTERSECTS 12.4 METRES ASSAYING 9.3% ZINC + 2.8% LEAD

AT THE MOUNT FRONSAC NORTH PROJECT

(Montreal – December 6 , 2017) Osisko Metals Incorporated (the “ Company” or “ Osisko Metals ”)

(TSX-V: OM; FRANKFURT: 0 B5) is pleased to announce the initial results from its maiden drilling

program on the Mount Fronsac North Project located 60 k ilometres west of Bathurst, New Brunswick. Drill

hole MF00-31-Wedge intersected 12.4 metres of 9.29% Zn and 2.84% Pb , and 45.1 grams per tonne

Ag.

Drill hole MF00-31-Wedge and another wedge cut from historical drill hole MF00-29, that is located 100m

south of MF00 -31-Wedge, were both drilled to confirm historical assays to comply with NI43-101

regulations that require using an accredited laboratory , and secondly to measure the variability of the

mineralization.

Additional drill holes MF17-43 & 44 were both drilled between MF00-29 and MF00-31 in order to test the

high-grade mineralization at different elevations. Assay results are pending.

An additional d rill hole located 100 metres north of MF00 -31-Wedge, MF17 -46, was drilled to test

mineralization located 80 metres up dip from historical drill hole MF00-22 that intersected 2.3 metres of

1.44% Cu, 2.37% Zn, 1.07% Pb, 37.6 g/t Ag and 0.4 g/ t Au . MF17 -46 encountered 21.6 metres of

predominantly massive sulphide s from 363.8 to 385.4 meters (19.0m true thickness ) hosted in a broader

zone of semi massive and disseminated sulphides and stringer sulphides. Assay results are pending.

The next holes that are planned will test a 250-metre down dip gap between two mineralized historical

drill holes located 1 10 metres north of drill hole MF17-46. The lower and upper holes contained 4.87

metres of 1.27% Zn, 0.46% Pb and 7.9 g/ t Ag and 1.94 metres o f 2.12% Zn, 0.59% Pb, and 7.8 g/ t Ag

respectively.

The recently announced acquisition of the mineral claims to the north (see news release dated November

27,2017) that hosts the historical drill hole MF00 -26 contains 7.0 metres of 1.84% Cu and a separate

zone of 7.0 metres of 1.93 % Zn that is situated within a broader halo of 22.5 metres of semi-massive to

massive sulphide s. This drill hole is located approximately 180 metres north of the next holes planned

and almost 300 metres north of drill hole MF00-46.

Jeff Hussey, President and CEO of Osisko Metals, commented: “The Mount Fronsac North deposit is a

large sulphide zone that is currently defined by w idely spaced drill holes. Our objective is to extend the

boundaries of the high grade zones within the broader envelope of sulphide mineralization . Confirming

the grades of historical drill holes is an important first step in this process , and so far we ha ve been

successful in replicating significant intersections”.

Quality Assurance / Quality Control

Osisko Metals adheres to a strict Quality Assurance and Quality Control program with regard to core

handling, sampling, transportation of samples and lab analyses. Drill core samples from Osisko Metals

were securely transported to its core facility in Bathurst New Brunswick where they were logged and

sampled. Samples selected for assay were shipped via secure transportation to Activation Laboratories

preparation facility in Fredericton New Brunswick. Pulps were analyzed at Activation Laboratories facility

in Ancaster, Ontario. Zinc, lead and copper were analyzed by assay grade peroxide fusion (total

digestion) with ICP -AES finish. Silver was analyzed by gravimetric fire assay and gold b y fire assay -

atomic absorption.

About Mount Fronsac North

The Mount Fronsac North deposit contains a historical, non-NI43-101 compliant, unclassified resource of

1.26 million tonnes grading 7.65 % Zn, 2.18 % Pb, 0.14% Cu, 40.3 g/t Ag, and 0.40 g/t Au. This high-

grade zone is hosted within approximately 14 million tonnes of low-grade, semi-massive (>60%) to locally

massive sulfides that occur in an envelope of quartz-sericite ± chlorite schist.

The high-grade deposit has a north -south strike length of 525 metres and a down dip length of 600

metres. Thick ness varies between 2 to 20 metres. The alteration and disseminated mineralization halo

has a maximum thickness of 140 metres and contains up to 50 percent fine to coarse -grained

disseminated pyrite. The pyritic envelope is 900 metres long and extends down dip over 1,000 metres.

Massive sulfides are found throughout this alteration envelope, but preferentially occur at or near the

upper contact.

About Osisko Metals

space with an emphasis on zinc. In 2017, the Company acquired over 50,000 hectares in t he Bathurst

Mining Camp (“BMC”) . The objective is to develop a multi -deposit asset base that could feed a central

concentrator. In parallel, Osisko Metals is monitoring several base metal oriented peers for acquisition

opportunities. In Québec, the Company acquired 42,000 hectares that cover 12 grass -root zinc targets

that will be selectively advanced through exploration . Osisko Gold Royalties Ltd. (TSX/N YSE: OR) and
