Bonterra Resources Inc. (TSX-V:BTR) (US:BONXF) (FSE:9BR1) is pleased to announce that the ongoing resource development program at the Gladiator Gold Deposit has extended the North, Footwall and Main Zones by 200 m down plunge to the east. High-grade intersections identified in step-out drilling east of the known mineralization demonstrates the potential for further expansion of the Gladiator Deposit, which remains open in all directions.

Bonterra continues to advance the development of the Gladiator Gold Deposit through definition drilling across all mineralized horizons. Follow up on previous step-out drilling has led to significant results at multiple zones, including 26.7 g/t Au over 3.1 m at the North Zone and 15.8 g/t Au over 3.3 m at the Main Zone.

Dale Ginn, VP Exploration, stated, “Bonterra once again delivers strong results from its resource development program at the Gladiator Gold Deposit. To that effect, we currently have four drills at the deposit to continue with step-out and definition drilling. Recent drill results highlight both the predictability of the mineralized zones and the potential for further expansion of high grade ore shoots at depth. The current step-out drilling demonstrates the potential to expand the Gladiator Deposit, which remains open in all directions.”

Highlights and Observations:

• Hole BA-17-53B extends the North, Footwall and Main Zones by 200 m down-plunge to the east with 6.2 g/t Au over 1.9 m, 4.8 g/t Au over 3.5 m and 4.9 g/t Au over 1.8 m.
• Hole BA-17-45B intersected the Main and South Zones 650 m below surface with 15.8 g/t Au over 3.3 m adding further definition to the high-grade core of the Main Zone.
   
• Hole BA-17-46 intersected the North Zone with 26.7 g/t Au over 3.1 m and the Main Zone with 8.8 g/t Au over 3 m, demonstrating the continuity of these zones.
   
• Results from six recent drill holes expand the size and demonstrate the continuity of the North, Footwall, Main and South Zones.
   
• 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 1,200 m, as well as a drilled depth of 1,000 m.
