Bonterra Discovers New South Zone West of Main Gladiator Gold Deposit

VANCOUVER, June 6, 2017 /PRNewswire/ - Bonterra Resources Inc. (TSX-V: BTR, US: BONXF, FSE: 9BR1) (the "Company" or "Bonterra") is pleased to announce that drilling from its ongoing resource development program discovered an additional parallel gold zone to the south and west of the main Gladiator Gold Deposit. The new zone lies within the "Rivage Gap" and was intersected by four (4) drill holes to date, with BA-17-12 which intersected 3.0 m of 8.8 g/t, being the most predominant and westerly hole to date.

Quick Highlights of Recent Drill Results:

• Emergence of new South Zone, intersected by four holes to date, and has been identified over a 500 m strike length to date.
• Multiple gold zones continue to be intersected in the "Rivage Gap" area, which confirms the existence of the Main and Footwall Gold Zones, and extends the North, Mid and South zones further to the west.
• Main and Footwall zones extended to the west, connecting them with the Rivage Gap area and confirming a strike length of over 1 km for each.
• Continuity of mineralization demonstrated in multiple horizons between the Gladiator Deposit and the Rivage Zone.
• Drilled dimensions of the Gladiator Deposit now outlined to a depth of 850 meters below surface, and a strike length of 1,200 meters (1.2 km).
• Gladiator remains open in all directions with drilling currently focused on the Deep East Zone, the Rivage Gap western side, and within large gaps or voids with currently little drill information.

Highlights and Observations:

• Hole BA-17-12 encountered multiple high grade intersections in the "Rivage Gap", and confirms and extends the new South Zone to the west, indicating an ~500 m strike length to date with the following result:
• 3.0 m grading 8.8 g/t Au (new South Zone) at ~275 m below surface.
• Hole BA-17-12 also intersected the main zone near surface in the "Rivage Gap" with:
• 2.0 m grading 11.1 g/t Au (Main Zone) at ~25 m below surface.
• Drilling at the "Rivage Gap", a 600 m long stretch of the Gladiator Deposit to the west that contains very little drill information to date, is clearly demonstrating continuity in multiple horizons between the Gladiator Deposit and the Rivage Zone.
• Continuity is providing a total drilled strike length to date on at least two horizons (Main and Footwall) of 1.2 km.

All intersections from the above table are located within a length or gap of drill information between the westernmost Rivage area and the known portion of the Gladiator Deposit. The high grade Main, Footwall and North Zones are in or near the sheared contact between mafic volcanic units and a mineralized felsic porphyritic intrusive.
