Bonterra Expands Mineralized Width and Grade at Gladiator Gold Deposit with

Significant Results on Multiple Zones; 18.5 g/t Au over 4.0 m Intersected in the South Zone

Vancouver, BC – December 5, 2017 : Bonterra Resources Inc. (TSX-V: BTR, US: BONXF,

FSE: 9BR1) (the “Company” or “Bonterra”) is pleased to announce continued success from its

ongoing Resource Development Program at the Gladiat or Gold Deposit. Drilling has further

increased the size of the high-grade core area of t he South Zone, with 18.5 g/t Au over 4.0 m

drilled in hole BA-17-42A, and significant width and grade was also encountered in the Footwall

Zone within drill hole BA-17-48, which yielded 10 g/t Au over 6.3 m. Additional drilling results

received also extended the North Zone down plunge and to the east. The Company is aggressively

completing its 2017 Resource Development Program, w ith four diamond drill rigs completing a

50,000 m program. Multiple holes are currently in t he lab awaiting completion with assays

pending.

Highlights and Observations:

• Drill holes BA-17-42A (18.5 g/t Au over 4.0 m) and BA-17-44 ( 11.9 g/t Au over 3.2 m)

in the South Zone increase and further define the size of the high-grade core area .

• Holes BA-17-42A and BA-17-48 improve the definition of the high-grade core of t he

Footwall Zone, with significant grade and width in hole BA-17-48, which intersected 10.1

g/t Au over 6.3 m .

• Holes BA-17-42 , BA-17-43B and BA-17-46 confirm the eastern continuity of the North

Zone, with BA-17-42 intersecting 9.6 g/t Au over 3.0 m. This recent drilling also extends

the North Zone down plunge to the east.

• Results from seven recent drill holes have expanded the size and demonstrate the continuity

of the North, Footwall and South Zones.

• To date, continuity of mineralization is now confir med over a total drilled strike

length on at least two horizons (Main and Footwall) of 1,200 m, as well as a drilled

depth of 1,200 m.

Dale Ginn, VP Exploration, stated, “Drill results from Gladiator continue to demonstra te

superior widths and grades in all five of our defin ed zones to date. These mineralized zones are

not only visible with sharp contacts, but are continuous and highly predictable. Stand alone high-

grade gold deposits in Canada, especially with exte nsive infrastructure and easy access, are

extremely rare and valuable and we look forward to demonstrating that Gladiator is among that

class.”

The Company plans to mobilize two additional drills (totaling six) to the property to support the

expanding Resource Development Program at Gladiator. The upcoming winter drilling campaign

will focus on further defining the Gladiator Gold Deposit to advance the completion of an updated

NI 43-101 Mineral Resource Estimate in 2018.
