Montreal, October 10, 2017. Niobay Metals Inc. (“NioBay” or the “Company”) (TSX-V: NBY) is pleased to announce the commencement of a diamond drilling campaign on the La Peltrie gold property located in Québec, on which Niobay can earn an interest of up to 65%. The La Peltrie property is currently wholly-owned by Midland Exploration Inc. (“Midland”). See press release of September 6, 2017 for details of the option agreement with Midland. The La Peltrie property consists of 520 claims totalling approximately 288 square kilometres and covers, over more than 25 kilometres, a series of NW-SE-trending subsidiary faults to the south of the regional Lower Detour Fault.

This drilling campaign will include a minimum of six (6) drill holes totalling 1,500 metres. The program is mainly designed to test new structural, geological, and geophysical targets identified following compilation work and OreVision® IP geophysical surveys conducted in 2016 and 2017 by Midland. These new high-priority targets include a major interpreted structure trending NW-SE, cross-cutting at a shallow angle a gold-bearing iron formation where historical drilling yielded grades of 0.24 g/t Au over 19.50 metres (drill hole 11-493-01) and 0.35 g/t Au over 9.30 metres (drill hole 11-493-02). Midland will be the operator of the exploration program.

The La Peltrie property is located approximately 25 kilometres southeast of Zone 58N, a high-grade gold zone in the Lower Detour area held by Detour Gold Corp., about 25 kilometers northwest of the former Selbaie Mine, which historically produced 56.5 million tonnes grading 1.9% Zn, 0.9% Cu, 38.0 g/t Ag and 0.6 g/t Au, and next to the B26 deposit currently held by SOQUEM. (Niobay cautions that the mineralization at Zone 58N, at the former Selbaie Mine and at the B26 deposit may not be indicative of the mineralization that may be identified on the La Peltrie property.)
