VANCOUVER, April 9, 2018/CNW/ -Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR1) (the "Company" or "Bonterra")is pleased to announce the first significant intersections of a new "sixth parallel" gold zone at the Gladiator Gold Deposit. This newly discovered gold zone, located approximately 50 msouth of the Barbeau Zone, is parallel to and geologically similar to the other five mineralized zones currently modelled at the expanding deposit. Additional drilling is now underway to test further to the south to intercept and expand this new zone. The ongoing drilling campaign, which will total ~70,000 m in 2018, includes infill and expansion drilling at the Gladiator Gold Deposit. Multiple drill holes are in the lab with assays pending.

Highlights and Observations:

A new gold zone was recently discoveredin Hole BA-18-09, at the Gladiator Gold Deposit, with 11.8 g/t Au over 2.6 mintercepted south of the Barbeau Zone, increasingthe number distinct mineralized gold zones to six.

Infill drill results continue to demonstrate the continuityof the deposit, highlighting the predictability of the mineralized zones.

Hole BA-18-12 intersected 16.3 g/t Au over 3.4 mat the South Zone at 266 mdepth. This intersection continues to confirm the continuity of the South Zone on the western side of the Gladiator Deposit.

Hole BA-18-11 intersected high-grade gold in five mineralized zones, including 10.1 g/t Au over 2.4 min the Barbeau Zone. This highlights the predictability of multiple mineralized zones and validates the geological model.

Hole BA-18-10A intersected 16.5 g/t Au over 2.2 min the Main Zone and confirms the continuous nature of the modelled mineralized 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.
