Revised: BonTerra Extends Western Extension of the Gladiator Deposit by 150 m to 600 m with 2.5 m of 137.4 g/t Gold

Vancouver, BC / TheNewswire / May 18, 2016: BonTerra Resources Inc. (TSX-V: BTR, US: BONXF, FSE: 9BR1) (the "Company" or "BonTerra") is pleased to announce that it has successfully extended the length of its Gladiator gold zones by an additional 150 m to a total strike length of 600 m to date. Assays from an additional eight (8) holes from its 2016 Exploration and Drill Program on its 100% owned Gladiator Gold Project located north of Val d'Or, Quebec have been received from the western extension and are reported below. To date, all of the 19 holes completed in 2016 have been reported from the winter drilling program designed to extend the western limits of the deposits.

Drill hole #19, targeting the lower and westernmost extents of the Gladiator zones, generated a high-grade intersection of 137.4 g/t over 2.5 m with coarse visible gold having been observed in the core. All of the drill holes reported in this press release are located at or within 50 meters of the known western extents of the Gladiator Deposits.

Nav Dhaliwal, President and CEO of BonTerra, commented: "Once again our team has pushed the limits of these deposits along strike and to depth in a significant manner. With only the western extension tested to-date, I look forward to beginning our push along strike to the east this summer."

2016 Drilling Program Update and Highlights:

• -2.5 m of 137.4 g/t Au in Hole BA-16-19 at westernmost and deepest limits of drilling to date in Main Zone, coarse visible gold was observed over a 0.5 m section of the core;

  -Intersection of 3.5 m of 12.0 g/t Au in Main Zone drilled less than 100 m below surface in Hole BA-16-14;

  -Extends Main Zone further to the west with intersection of 3.0 m of 15.0 g/t Au, at nearly 200 m below surface in Hole BA-16-17;

  -Hole BA-16-15 extends Footwall Zone further to the west with intersection of 2.6 m of 8.6 g/t Au at 100 m below surface;

  -The Gladiator Deposits, to-date, are outlined over a strike length of 600 m long by 450 m deep, where 23 new drill holes (2015 and 2016) have extended the main deposits and discovered 3 new parallel zones;

  -New drill information demonstrates that three zones (Footwall, Main and Intrusive) continue along strike, while three new zones (North Shear 1, North Shear 2 and South) have been identified both to the north and south of the previously known zones.

  -8,300 m drilled during 2016 in 19 holes on the western extension of Gladiator Deposit;

  -Visible gold was identified in 16 of the 19 holes.

*Stated lengths are core width as drilled, true widths have not yet been determined.

Dale Ginn, Vice President of Exploration of BonTerra, added: "While many gold deposits of the Archean shear hosted type are characterized by numerous plunging bodies of relatively short length along a fault structure, Gladiator is demonstrating remarkable continuity along strike and to depth while the presence of mineralized felsic intrusive along the structures is also indicative strength in the system. Our experience and knowledge of the system was greatly enhanced by our 2016 Winter Drill Program and we look forward to applying our knowledge towards the east."

Upcoming Program and Next Steps

The western extension of the Gladiator Deposit was targeted based on interpretation of recent geophysical programs and extension of known data from the existing Gladiator zones. With the ice drilling program now complete for the winter season, the project will now focus on the eastern and depth extensions from land-based drill sites. This program is expected to continue with drilling the main zones, following up on the recent discoveries, applying drilling in order to extend the deposits to the east, and following up on targets identified on the Coliseum Property to the west.

BonTerra Resources Quick Facts:

• -7,563-hectare (Gladiator Project) in the Urban-Barry Camp in Quebec containing:

  • -Using a 4 g/t Au cut-off grade, the project currently contains an inferred resource of 905,000 tonnes, grading 9.37 g/t Au for 273,000 ounces of gold. Of note, ~90% of the worlds operating mines have an average gold grade less than 8 g/t. Mineral Resource Estimate and technical report filed July 27, 2012, Snowden Mining Consultants.

    -2016 Exploration Program underway - up to 25,000 meters utilizing minimum of two drill rigs at its 100% owned Gladiator Gold Project to expand current gold resource.

  -2,165-hectare (Larder Lake Property) in the Cadillac-Larder Break Camp in Ontario (refer to March 17, 2016 news release highlighting historical gold resource).
