BONTERRA EXTENDS NEW SOUTH ZONE TO 600 M BELOW SURFACE DRILLING INTERSECTS 3.8M OF 12.0 G/T AU

Bonterra Resources Inc.'s current resource development program in and around the Gladiator gold deposit has successfully further extended the newly discovered South gold zone (see release dated June 6, 2017) by over 300 metres to depth. Drill hole BA-17-22, the first hole collared from the south island location (hangingwall), intersected 3.8 metres of 12 grams per tonne at 600 m below surface. Additional results have also been received which also considerably extend to depth the Main and North zones.

Nav Dhaliwal, chief executive officer and president, stated: "Results continue to significantly increase the overall dimensions of the Gladiator gold deposit in all directions. We are currently focused on our aggressive resource development program and remain in a strong financial position, having raised $40-million in the first half of 2017. The addition of significant strategic partners and shareholders validates not only the Gladiator gold deposit but management's focus and strategy going forward."

Highlights and observations

• Hole BA-17-22 extends to depth by over 300 m the new South zone with 3.8 m of 12.0 g/t at 600 m below surface. This is the first intersection from the south island location series of holes that allow for deeper drilling from a southern hangingwall location. This hole is also anticipated to cut through the other known Gladiator zones at depth and assays are pending for these remaining zones.
• Hole BA-17-15 extends the Main zone to depth from previous drilling with 4.0 m of 9.1 g/t at 700 m below surface.
• Hole BA-17-21 has deepened the North zone to nearly 500 m or greater for below surface with 3.0 m of 21.5 g/t.
• Continuity of mineralization is now confirmed over a total drilled strike length (to date) on at least two horizons (Main and footwall) of 1.2 kilometres as well as a drilled depth of one km.
• New results provide drilled continuity to depths of 500 to 700 m for additional zones (North and South).

Dale Ginn, vice-president of exploration, added: "The extension of the new South zone to depth is significant, noting it is the first result from our southern island location. This location provides access to drill the Rivage Gap area to depth from the hangingwall side of the Gladiator deposit and enables us to extend the under plunge areas of the other four zones as well."

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.
