Osisko Metals Intersects 13.16% Zinc + Lead Over 8.0 Metres in the Titan Zone of the Key Anacon Project in Bathurst

MONTREAL, Nov. 13, 2018 - Osisko Metals Inc. (the “Company” or “Osisko Metals”) (TSX-V: OM; FRANKFURT: OB5) is pleased to announce results from 16 drill holes from the Titan Zone on its wholly owned Key Anacon project located 20 km south of the city of Bathurst, New Brunswick. The Titan Zone deposit is separate from the Main Zone deposit, located 1,500 metres to the northeast, and not included in the historical resource estimate.

Drill hole KAT-18-08 cut 8.0 metres of massive sulfides grading 9.53% zinc, 3.63% lead, 0.20% copper and 68.62 g/t silver in an area 140 metres up plunge from drill hole KA-18-01 (see news release of June 28, 2018 and the attached Titan Zone Longitudinal map. Furthermore, this intersection is located 60 metres northwest of historical drill hole KA-01-09 that cut 6.8 metres of 5.78% zinc, 2.07% lead, 0.52% copper and 53.3 g/t silver. KAT-18-08 also intersected a separate copper-rich zone grading 1.18% copper, 0.82% zinc, 0.12% lead and 8.9 g/t silver over 16.2 metres, located below the zinc-lead zone, as seen in the Titan Zone Copper Longitudinal map. Additionally, drill hole KAT-18-13 intersected the same near-surface high grade mineralized zone 75 metres below KAT-18-08 and cut 6.5 metres grading 5.34% zinc, 2.81% lead, 0.62% copper and 24.4g/t silver. This intersection occurs within an overlapping polymetallic zone of 26.6 metres grading 0.93% copper, 1.79% zinc, 0.88% lead and 19.08 g/t silver.

Finally, drill hole KAT-18-10 intersected 6.1 metres of 4.3% zinc, 2.82% lead and 44.07 g/t silver at a vertical depth of 170 metres. This hole extends the deposit boundary towards the southeast and is open along strike at that depth.

Jeff Hussey, President and CEO of Osisko Metals, commented: “The drilling on this project is quickly reinforcing our belief that Key Anacon is the best exploration and development asset in the Bathurst Camp. As with our last results, which increased the size of the Main Zone, these results at the Titan Zone are revealing significant new mineralization. Drilling is now targeting near surface, high grade mineralization in the Titan Zone that overlaps with copper-rich mineralization. Copper grades in this zone can be up to five times grades typically seen across the Bathurst Camp. This copper zone extends for a kilometer to the northwest where it is roughly outlined by only three 400-metre spaced drill holes.

We have now defined within the Titan Zone a Zinc + Lead rich deposit that steeply plunges to over 1,100m depth towards the southeast where KA01-15B encountered a 75-metre-thick interval of massive sulphides containing 3 separate zones: 5.1% Zinc + Lead over 9.3 metres, 9.25 % Zinc + Lead over 13.0 metres and 5.55% Zinc + Lead over 24.3 metres. The Titan Zone is now at least twice as long vertically when compared to the nearby Main Zone.”

The near-term exploration focus on the Titan Zone is to outline the size of the higher-grade zinc and lead mineralization and delineate the adjacent and overlapping copper-rich zone. The 2018 drill program has grown the size of both the Titan Zone and the Main Zone, upgrading the significance of this project.

It is worth noting that the Key Anacon Horizon is the contemporaneous equivalent of the Brunswick Horizon (“BH”). More recent geological interpretations connect the BH between Key Anacon and the former Brunswick No.12 and No. 6 Mines (~150Mt @ 12% Zinc + Lead). Continuing south of the No.6 Mine, the BH runs through the Gilmour South Deposit and continues for 30 kilometres along the Portage River Anticline before reaching the Key Anacon Project. (See BH along the Portage River Anticline - Plan View Section).

The strike length between Gilmour South and Key Anacon has barely been explored. As work continues, other areas of interest are also emerging on the BH, which is one of the most prolific base metal horizons in the world.

About Key Anacon

The Key Anacon project is located approximately 20 km south of the town of Bathurst, New Brunswick and 16 km southeast of the former Brunswick No.12 mine. It is accessible by paved roads. The property contains two known Bathurst-type volcanogenic massive sulphide deposits containing zinc, lead, copper and silver. The Key Anacon Main Zone and Titan Zone deposits are situated at the same stratigraphic horizon that hosted the Brunswick No. 12 & No. 6 mines. The property covers approximately 12 kilometres of favorable Nepisiguit Falls stratigraphy that also extends onto the surrounding claims held 100% by Osisko Metals.

No mineral resource estimates have been calculated under NI43-101 guidelines. Except for exploration programs conducted in 1992-1993 and 2000, almost all of the drilling was completed in the 1950’s and 60’s, prior to currently required standards for quality assurance and quality control. The earlier drilling led to the establishment of a 460 metre-deep shaft, a vent raise, eight levels and three sub-levels at the Main Zone. The Government of New Brunswick, Department of Energy and Resource Development, Energy and Mines Division reports the Main Zone deposit as having a historical resource (Non-NI 43-101 compliant) of 1.87 million tonnes grading 6.93% Zn, 2.63% Pb, 0.16% Cu, and 84 g/t Ag in multiple folded lenses. The deposit is open at depth and along strike.

Exploration potential at Key Anacon and the Company’s adjacent properties is considered to be excellent on the basis of the presence of the Brunswick Horizon stratigraphy and the expansive zones of mineralization and alteration. Both the Titan Zone and Main Zone are open at depth and along strike. Exploration and development in the 1950’s and 1960’s was terminated due to the pullback of the zinc commodity price at that time. Since then, only two minor exploration programs were conducted by major mining companies.
