Mergers & Acquisitions Property Options & Staking

OSISKO METALS SIGNS PURCHASE AGREEMENT TO ACQUIRE THE KEY ANACON PROPERTY

IN THE BATHURST MINING CAMP

(Montreal – December 27, 2017 ) Osisko Metals Incorporated (the “ Company” or “ Osisko Metals ”)

(TSX-V: OM; FRANKFURT: OB5) 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 no t NI 43-101 compliant , n o

known current mineral resource estimate has been conducted and t he 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 n o 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.

Key Anacon was last explored in 2001 . The potential on the property as well as on the adjacent Osisko

Metals claims is considered to be excellent based on the presence of these significant deposits hosted

within the considerable strike length of the favorable Brunswick Horizon , with alteration and folding

typically associated to BMC deposits.

THE KEY ANACON TRANSACTION

Pursuant to Purchase Agreement between the Vendor and Osisko Metals, the Company will acquire a

100% undivided interest in the Key Anacon Claims and will have the exclusive rights to explore and

develop the Project in consideration of:

i. $1 million ($750,000 payable in cash and $250,000 payable in the equivalent of Osisko

Metals common shares valued at the 5-day VWAP preceding the day of the close of the

transaction);

3

ii. Additional $500,000 (payable in the equivalent of Osisko Metals common shares valued

at the 20-day VWAP, 24 months following the signature of a definitive agreement);

iii. Additional $500,000 in cash on commencement of commercial production.

The Transaction is subject to the TSX Venture Exchange approval.

Jeff Hussey, President and CEO of Osisko Metals, commented: “ We are very happy to announce the

purchase of the historical Key Anacon deposits as they will contribute significant resources and could

become the cornerstone of Osisko Metals central concentrator multi -deposit concept in the Eastern

portion of the BMC. Drilling is being planned and will consist of approximately 12,000 metres to explore

the area in an attempt to increase the global h istorical resources and upgrade them to NI43 -101

standards.”
