Bonterra Expands Mineralized Width and Grade at Gladiator Gold Deposit with Significant Results on Multiple Zones; 18.5 g/t Au over 4.0 m Intersected in the South Zone

VANCOUVER, Dec. 5, 2017 /PRNewswire/ - Bonterra Resources Inc. (TSX-V: BTR, US: BONXF, FSE: 9BR1) (the "Company" or "Bonterra") is pleased to announce continued success from its ongoing Resource Development Program at the Gladiator Gold Deposit. Drilling has further increased the size of the high-grade core area of the South Zone, with 18.5 g/t Au over 4.0 m drilled in hole BA-17-42A, and significant width and grade was also encountered in the Footwall Zone within drill hole BA-17-48, which yielded 10 g/t Au over 6.3 m. Additional drilling results received also extended the North Zone down plunge and to the east.  The Company is aggressively completing its 2017 Resource Development Program, with four diamond drill rigs completing a 50,000 m program. Multiple holes are currently in the lab awaiting completion with assays pending.

Highlights and Observations:

• Drill holes BA-17-42A (18.5 g/t Au over 4.0 m) and BA-17-44 (11.9 g/t Au over 3.2 m) in the South Zone increase and further define the size of the high-grade core area.
• Holes BA-17-42A and BA-17-48 improve the definition of the high-grade core of the Footwall Zone, with significant grade and width in hole BA-17-48, which intersected 10.1 g/t Au over 6.3 m.
• Holes BA-17-42, BA-17-43B and BA-17-46 confirm the eastern continuity of the North Zone, with BA-17-42 intersecting 9.6 g/t Au over 3.0 m.  This recent drilling also extends the North Zone down plunge to the east.
• Results from seven recent drill holes have expanded the size and demonstrate the continuity of the North, Footwall and South Zones.
• To date, continuity of mineralization is now confirmed over a total drilled strike length on at least two horizons (Main and Footwall) of 1,200 m, as well as a drilled depth of 1,200 m.

Dale Ginn, VP Exploration, stated, "Drill results from Gladiator continue to demonstrate superior widths and grades in all five of our defined zones to date. These mineralized zones are not only visible with sharp contacts, but are continuous and highly predictable. Stand alone high-grade gold deposits in Canada, especially with extensive infrastructure and easy access, are extremely rare and valuable and we look forward to demonstrating that Gladiator is among that class."

The Company plans to mobilize two additional drills (totaling six) to the property to support the expanding Resource Development Program at Gladiator. The upcoming winter drilling campaign will focus on further defining the Gladiator Gold Deposit to advance the completion of an updated NI 43-101 Mineral Resource Estimate in 2018.
