Bonterra Resources Inc. (TSX-V: BTR) (US: BONXF) (FSE: 9BR1) is pleased to announce the latest drilling results from the ongoing resource development program at the Gladiator Gold Deposit, including an intersection of 29.6 g/t Au over 3.0 m at the South Zone. This indicates the presence of a new high-grade chute and is open at depth. Recent infill drilling results demonstrate the continuity of mineralization and increase the thickness of all defined zones. Step out drilling revealed new areas of high-grade mineralization and has expanded the known extents of mineralization along multiple zones.

Highlights and Observations:

• Infill and extension drill results continue to validate the Gladiator model.
• BA-18-53A intersected multiple high-grade gold zones including 29.6 g/t Au over 3.0 m at the South Zone, indicating the presence of a new high-grade chute, expanding the known extents of mineralization and opening the South Zone at depth.
• BA-18-53A intersected multiple structures in the North Zone with 6.5 g/t Au over 2.0 m and 4.0 g/t Au over 3.0 m.
• BA-18-53A also intersected with Footwall Zone with 4.5 g/t Au over 3.0 m, increasing the thickness of the zone at 600 m below surface.
• BA-18-54 further defines the North Zone with 9.4 g/t Au over 3.0 m. This intersection increases the grade and indicates the continuity of the North Zone in the eastern part of the deposit.
• BA-18-58 intersected the South Zone at 600 m below surface with 12.3 g/t Au over 1.5 m, connecting the mineralization at the Rivage area to a high-grade chute at depth.
• BA-18-58 intersected the Main Zone, expanding the extents of known mineralization up-plunge with 4.1 g/t Au over 1.5 m.
• BA-18-62 intersected the Main Zone, increasing the size of the high-grade chute 400 m below surface with 17.7 g/t Au over 2.0 m.
• BA-18-62 intersected two structures in the South Zone with 9.8 g/t Au over 2.0 m and 5.8 g/t Au over 2.0 m, proving continuity.
• To date, continuity of mineralization is now confirmed over a total drilled strike length on at least four horizons (North, Footwall, Main and South) of 1,300 m, as well as a drilled depth of over 1,000 m.

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.
