Bonterra Resources Inc. (TSX-V: BTR) (OTCQX: BONXF) (FSE: 9BR1) is pleased to announce the latest drilling results from the ongoing resource development program at the Gladiator Deposit, including and intersections of 37.5 g/t Au over 3.3 m at the South Zone. Step out drilling continues to reveal new areas of high-grade mineralization and expand known extents of mineralization. Recent definition drilling results demonstrate the continuity of mineralization in multiple zones.

Highlights and Observations:

• BA-18-63 intersected the South Zone with 37.5 g/t Au over 3.3 m, proving continuity of the high-grade trend within the zone.
• BA-18-63 also intersected multiple structures at the Main Zone with 9.1 g/t Au over 1.0 m and 8.9 g/t Au over 1.0 m.
• BA-18-64 intersected the Footwall, Main and South Zones demonstrating the continuity of gold bearing quartz veins across multiple zones.
• BA-18-65 intersected the North Zone with 11.9 g/t Au over 2.0 m and extended the Main Zone down plunge with 11.3 g/t Au over 1.6 m.
• BA-18-65 also expanded the South Zone, extending the zone towards surface at 700 m depth with 9.8 g/t Au over 2.0 m.
• BA-18-67A further defines Main Zone with 8.5 g/t Au over 2.0 m, proving the continuity of the zone at 400 m below surface.
• BA-18-69 extended the Main Zone in the Rivage area with 9.0 g/t Au over 2.0 m. This intersection expands the zone down plunge and opens up the Rivage area for further extension at depth.

The ongoing resource development program continues to expand and define the Gladiator Gold Deposit ahead of the updated mineral resource estimate scheduled for Q4 2018. Drilling to be included in the upcoming mineral resource estimate has now been completed. Drilling continues with three drills at the deposit focused on extension drilling along strike to the northeast and southwest.

*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.
