Bonterra Extends Multiple Gold Zones by Additional 300 Meter Along Strike and Depth at Gladiator Gold Deposit

VANCOUVER, Sept. 18, 2017 /PRNewswire/ - Bonterra Resources Inc. (TSX-V: BTR, US: BONXF, FSE: 9BR1) (the "Company" or "Bonterra") is pleased to announce that the ongoing resource development program in and around the Gladiator Gold Deposit has successfully further extended the Main, Footwall and North Zones by increasing the strike and depth by up to 300 m depth to the known mineralized horizons. Results from six recent drill holes significantly expand the size and confirm the continuity of the Gladiator Gold Deposit.

Highlights and Observations:

• Results from six recent drill holes significantly expand the size and confirm the continuity of the Gladiator Gold Deposit.
• Holes BA-17-20, BA-17-28, BA-17-31 and BA-17-32 collectively add 300 m depth and strike to the Main Zone. This extension occurs under plunge to the west below the Rivage Gap to a depth of over 650 m. A highlight of this significant extension is BA-17-20 which intersected 3.0 m of 10.4 g/t Au at 550 m below surface.
• Hole BA-17-23 extended the Footwall Zone to 400 m below surface under plunge with 3.0 meters of 10.1 g/t Au.
• Holes BA-17-30 and BA-17-31 extend the North Zone to depth by 100 m below BA-17-21: 21.5 g/t Au over 3 meters (see release dated July 20, 2017).
• Continuity of mineralization is now confirmed over a total drilled strike length (to date) on at least two horizons (Main and Footwall) of 1,200 m, as well as a drilled depth of 1,000 m.

Nav Dhaliwal, CEO and President, stated, "Our resource development program at the Gladiator Gold Deposit continues to successfully extend the western mineralized zones along strike and at depth. The predictability of our geological model is now considered to be dependable in projecting the on-strike and at-depth geometry of gold-bearing zones. In addition to once again expanding the size of the Gladiator Deposit, our geological model has demonstrated additional success up to 8 km westward, in the southern part of our Coliseum property (see press release of September 15, 2017)."

• Stated lengths are core width as drilled, true widths vary and average between 60 and 80 percent of drilled widths. Core axis angles of the intersection contacts and surrounding rock units average 55 to 70 degrees.
