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, BC – June 4, 2018: 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 dril l 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 m at 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 a rea 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 1,2 00 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 dri ll 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 activ e drills, four focused on the definition and expansion of the

Gladiator Gold Deposit, and one drill focused on exploration ta rgets 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.
