Osisko Metals Signs Purchase Agreement to Acquire the Key Anacon Property in the Bathurst Mining Camp

MONTREAL, QUEBEC--(Marketwired - Dec. 27, 2017) - Osisko Metals Incorporated (the "Company" or "Osisko Metals") (TSX VENTURE:OM)(FRANKFURT:0B5) is pleased to announce that it has signed a Definitive Purchase Agreement to acquire a 100% undivided interest in the Key Anacon claims and surrounding area ("Key Anacon") from Hunter Brook Holdings Limited (the "Vendor").

Key Anacon is located within the Bathurst Mining Camp ("BMC") and is roughly 19 km due south of the town of Bathurst, New Brunswick and 16 km southeast of the former Brunswick #12 Mine. Key Anacon is comprised of 45 claim units with a total surface area of 981 hectares and hosts approximately 12 kilometres of the Brunswick Horizon, which extends onto adjacent and surrounding claims held by Osisko Metals.

Project Highlights

Key Anacon contains two (2) significant Bathurst-type volcanogenic massive sulphide deposits. Both the Main and East Deposits are hosted within the Brunswick Horizon stratigraphy that is similar to the former Brunswick No. 12 Mine host rocks. Key Anacon's historical resources are not NI43-101 compliant, no known current mineral resource estimate has been conducted and the drill data available pre-dates current regulations and quality control standards.

The New Brunswick Ministry of Energy, Mines and Petroleum Mineral Occurrence Database reports that the Main deposit contains historical resources that total 1.87 million tonnes grading 6.93% Zn, 2.63% Pb, 0.16% Cu, and 84g/t Ag in multiple, folded lenses (Source: 2003, Economic Geology, Monograph 11). Key Anacon has been drilled from both surface and underground. Although no production is known, historical pre-production development includes a 460-metre shaft, a vent raise, eight development levels and three sub-levels. Exploration potential is considerable below the deposit at 400 metres, and along strike.

The Key Anacon East Deposit is located 1.5 km along strike to the northeast from the Main Deposit and it has been intersected by several holes. The best intersection was reported in a press release dated August 16, 1993 by Rio Algom on drill hole DDH 93-42 that intersected 19.9 metres grading 7.86% Zn, 3.58 % Pb, 0.33% Cu and 78 g/t Ag within a mineralized interval grading 3.38% Zn, 1.35% Pb, 0.75% Cu and 40.94 g/t Ag over 82.3 metres.
