Bonterra Further Increases the Width and Strike Length of the Gladiator Gold Deposit; 9.4 m of 8.2 g/t Au Intersected in the Main Zone

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 increased the width of the Main Zone and extended the strike length of multiple gold-bearing horizons. The results from the current drilling campaign continue to expand the size and further confirm the continuity of the Gladiator Gold Deposit. Noting the aggressive drill program at Gladiator, assays from multiple drill holes are pending in lab, and the Company anticipates additional drill results in the near future.

Highlights and Observations:

-Results from six (6) recent drill holes have increased the width of the Main Zone and have extended the strike length of the Footwall and North Zones.

-Hole BA-17-38 extends the North Zone down plunge to 700 m below surface with 4.0 m of 7.3 g/t Au including 24.8 g/t over 1.0 m.

-Hole BA-17-38 increases width and grade down plunge in the Main Zone with 9.4 m of 8.2 g/t Au at 800 m depth.

-Hole BA-17-37 confirms the eastern continuity of the South Zone with 1.5 m of 17.6 g/t Au at 500 m depth.

-Hole BA-17-39B extends the Footwall Zone to the east below surface with 5.0 m of 11.5 g/t Au at 500 m below surface.

-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.

Nav Dhaliwal, CEO and President, stated,”We continue to establish the Gladiator Gold Deposit as a very large gold system, with multiple parallel gold horizons that continue to be expanded along strike and also appear to show signs of increased width, as shown in hole BA-17-38, where 8.2 g/t Au over 9.4 m was intersected. Since 2011, approximately 88,500 m of drilling has been completed at the Gladiator Gold Deposit, which includes over 40,000 m so far in 2017. As we approach our winter drill program, we are looking to expand up to six drill rigs to ensure we continue our expansive resource development program. Because of our continued drilling success over the last two years at Gladiator, we have a high level of confidence that in 2018, we will be in a position to significantly upgrade the size of the geological model and complete a sizable mineral resource update.”

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.
