Bonterra Continues to Expand Gladiator Gold Deposit West to Rivage Gap and Intersects Additional New North Zone

VANCOUVER, 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 Gap" 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, continue 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 of 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 intersections in the Rivage Gap, especially extending the new North zone to the west, giving the following results: 4.2 metres grading 9.5 grams per tonne gold (North zone) at about 50 m below surface and 4.0 m grading 10.0 g/t Au (Footwall zone) at about 200 m below surface.
  • Holes BA-17-08 and BA-17-10 each intersected four distinct 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: 3.5 m grading 8.4 g/t Au (Footwall zone) at about 150 m below surface and 1.0 m grading 8.0 g/t Au (Mid zone) at about 200 m below surface.
  • Holes BA-17-07 and BA-17-09 extended the Main and Footwall zones to the west, effectively joining them with the Rivage area, confirming the strike length of over one km for each. BA-17-07 was also the deepest intersection yet recorded in the Rivage Gap area to date: 3.0 m grading 12.0 g/t Au (Main zone) at about 300 m below surface and 1.8 m grading 9.0 g/t Au (Footwall zone) at about 50 m below surface.
  • Drilling at the Rivage Gap, a 600 m long stretch of the Gladiator deposit to the west that contains very little drill information, is clearly 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 two horizons (Main and Footwall) of 1.2 km.

* Stated lengths are core width as drilled, true widths 
vary and average between 60 and 80 per cent of drilled 
widths. Core axis angles of the intersection contacts and 
surrounding rock units average 55 to 70 degrees.


All intersections from the table are located within a length or gap of drill information between the westernmost Rivage area and the known portion 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.
