Bonterra Further Extends the Gladiator Gold Deposit to the West Intersects 34.3 g/t Au over 2.8 m in the North Zone

VANCOUVER, June 4, 2018 /CNW/ - Bonterra Resources Inc. (TSX-V: BTR, US: BONXF, FSE: 9BR1) (the "Company" or "Bonterra") is pleased to announce the latest drilling results from the ongoing resource development program at the Gladiator Gold Deposit, including an intersection of 34.3 g/t Au over 2.8 m, which further extended the South Zone to the west by approximately 50 m. Positive assay results from ten recent drill holes have extended the known dimensions of the mineralization in multiple zones westward and to surface at the Rivage Gap area.

"Our winter drill campaign has been completed and was successful in expanding and defining the Gladiator Gold Deposit. We are now excited to commence our spring and summer drill program, which will focus on further definition of the deposit for the upcoming resource update in the latter part of 2018, but to also test regional priority targets to the south west and north east,"commented Nav Dhaliwal, President and CEO of Bonterra.

Highlights and Observations:

• Hole BA-18-25 intersected 34.3 g/t Au over 2.8 mat the North Zone, extending the deposit westward by approximately 50 m in the Rivage area.
  
  
• Infill drill holes BA-18-14 and BA-18-22A confirm continuity of the South Zone at depth and the extend the South Zone under plunge with 19.8 g/t Au over 1.2 m in BA-18-22A.
  
  
• Hole BA-18-15 extends the Main Zone to surface at the Rivage Gap with 13.9 g/t Au over 2.0 m.
  
  
• Hole BA-18-19 extends the Footwall down plunge with 13.4 g/t Au over 1.0 m at 550 m below surface.
  
  
• Hole BA-18-20 extends North Zone to surface at the Rivage Gap area with 14.2 g/t Au over 1.0 m.
  
  
• Infill drill results continue to demonstrate the continuity of the deposit, highlighting the predictability of the 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 over 1,000 m.

Winter Drilling Completed – Spring/Summer Drill Program Initiated

Bonterra has completed the winter drilling campaign, which was focused on step-out and definition drilling at the deposit. The campaign successfully extended the deposit westward, opening multiple zones for further expansion from surface to depth. Multiple drill holes from the winter drilling campaign are in the lab with assays pending.

The 2018 resource development program, comprised of 70,000 m of drilling at the Gladiator Gold Project continues with five active drills, four focused on the definition and expansion of the Gladiator Gold Deposit, and one drill focused on exploration targets west of the deposit. The Company is currently mobilizing a sixth drill to the St. Cyr Gold Prospect to follow up on drilling that was completed as part of the winter drilling campaign.
