Osisko Metals Signs Purchase Agreements to Acquire Strategic Claims Adjacent to the Mount Fronsac North Deposit

MONTREAL, QUEBEC--(Marketwired - Nov. 27, 2017) - Osisko Metals Incorporated (the "Company" or "Osisko Metals") (TSX VENTURE:OM)(FRANKFURT:0B5) is pleased to announce that it has signed a formal Purchase Agreement to acquire, from four vendors (The "Vendors"), a 100% interest in 4 claim groups (the "Properties") in the Mount Fronsac North area in the Bathurst Mining Camp ("BMC"). The Properties are comprised of a total of 39 claim units that have an approximate surface area of 850 hectares. Three of these claim groups host the northern extension and downdip potential of the Mount Fronsac North Deposit that was acquired by Osisko Metals in July 2017 (see NR dated July 6, 2017).

A previous drill hole (MF00-26) intersected several intervals Cu-Pb-Zn mineralization within a wide envelope of strongly altered and pyritized mineralization that is the north plunging extension of the Mount Fronsac North deposit. Hole MF00-26 intersected 7.0 metres grading 1.93% Zn (384.0-391.0 metres) as well as 7.0 metres grading 1.84% Cu (399.0-406.0 metres). The mineralized envelope is comprised of a 22.5-metre-wide zone (379.0-401.5 metres) of semi-massive to massive sulphides. Only limited wide spaced drilling was conducted to follow up on these results and the current Mount Fronsac North drill program will test this area again very soon.

The fourth claim group that was acquired is a separate block and it is located 5 km east of the Mount Fronsac North Deposit. This claim block hosts similar mineralized favourable stratigraphy that has had limited drilling. However, one hole in this area intersected 29.9 metres of 1.5% Zn and 0.5% Pb. Untested gravity anomalies and significant lead soil anomalies exist up-ice from this drilling. Osisko Metals also staked adjacent claims in the area to create a coherent land package covering similar stratigraphy.

Jeff Hussey, President and CEO of Osisko Metals, commented: "We are happy to announce another acquisition in the western half of the BMC. The Mount Fronsac North Deposit is a relatively large sulphide deposit that hosts high grade mineralization locally. The larger volume of sulphide mineralization is evidence of a significant volcanogenic system that we will evaluate and explore."
