Bonterra Continues to Expand Gladiator Gold Deposit West to Rivage Gap

and Intersects Additional New North Zone

Vancouver, BC – May 16, 2017 : Bonterra Resources Inc. (TSX-V: BTR, US: BONXF, FSE :

9BR1) (the “ Company ” or “ Bonterra ”) is pleased to announce that ongoing drilling to the west

of the main Gladiator Deposit within the “Rivage Ga p” has encountered multiple high grade

intersections as well as a major strike length extension of the new North horizon.

Quick Highlights of Recent Drill Results:

• Multiple high grade intersections encountered in the Rivage Gap and extends the new

North zone to the west.

• Four distinct zones intersected in the “Rivage Gap” area, confirming the existence of the

Main and Footwall zones, plus extending to the west the North and Mid zones.

• Main and Footwall zones extended to the west , connecting them with the Rivage Gap

area.

• Results confirm the strike length of over 1 km for each of the Main and Footwall Zones.

• Drilling intersects deepest mineralization to-date in Rivage Gap area , at 330m below

surface.

• Continuity of mineralization demonstrated in multiple horizons between the Gladiator

Deposit and the Rivage Zone.

• Drilled dimensions of the Gladiator Deposit now outlined to a depth of 850 meters below

surface, and a strike length of 1,200 meters (1.2 km) .

• Gladiator remains open in all directions with drilling currently focused on the Deep East

Zone, the Rivage Gap western side, and within large gaps or voids with currently little drill

information.

Nav Dhaliwal, CEO and President of Bonterra, stated : “Results from the Rivage Gap, or the

western area of the Gladiator Gold Deposit, continu e to add positive value to the understanding

of the geological model and the potential addition of significant new resources. A recent

interpretation has determined that the Rivage Gap is part of the main mineralized system, and our

technical team is currently confirming the impact o f what the most recent results clearly

demonstrate. We are excited with the continued positive results from within the Rivage Gap area,

and look forward to further extending these zones, similar to our success within the main Gladiator

area.”

Highlights and Observations:

• Hole BA-17-04 encountered multiple high grade inter sections in the “Rivage Gap”,

especially extending the new North zone to the west, giving the following results:

o 4.2 m grading 9.5 g/t Au (North Zone) at ~50 meters below surface.

o 4.0 m grading 10.0 g/t Au (Footwall Zone) at ~200 meters below surface.

• Holes BA-17-08 and BA-17-10 each intersected four d istinct zones in the “Rivage Gap”

area, confirming the existence of the Main and Footwall zones, plus extending to the west

the North and Mid zones, highlighting the following results:

o 3.5 m grading 8.4 g/t Au (Footwall Zone) at ~150 meters below surface.

o 1.0 m grading 8.0 g/t Au (Mid Zone) at ~200 meters below surface.

• Holes BA-17-07 and BA-17-09 extended the Main and F ootwall zones to the west,

effectively joing them with the Rivage area, confir ming the strike length of over 1 km for

each. BA-17-07 was also the deepest intersection y et recorded in the Rivage Gap area to

date.

o 3.0 m grading 12.0 g/t Au (Main Zone) at ~300 meters below surface.

o 1.8 m grading 9.0 g/t Au (Footwall Zone) at ~50 meters below surface.

• Drilling at the “Rivage Gap”, a 600 meter long stre tch of the Gladiator Deposit to the west

that contains very little drill information, is cle arly demonstrating continuity in multiple

horizons between the Gladiator Deposit and the Rivage Zone. This continuity is providing

a total drilled strike length to date on at least t wo horizons (Main and Footwall) of 1.2

kilometers.

• Stated lengths are core width as drilled, true widths vary and average between 60 and 80 percent of drilled

widths. Core axis angles of the intersection contacts and surrounding rock units average 55 to 70 degrees .

All intersections from the above table are located within a length or gap of drill information

between the westernmost Rivage area and the known p ortion of the Gladiator Deposit. The high

grade Main, Footwall and North Zones are in or near the sheared contact between mafic volcanic

units and a mineralized felsic porphyritic intrusive.
