BONTERRA QUEBEC EASTERN EXTENSION GOLD ASSAYS

Vancouver, BC - September 7, 2011: BonTerra Resources Inc. (TSX.V: BTR; FSE: 9BR) (the "Company", "BonTerra") continues to receive thick widths of high grade gold on its Eastern Extension property (the "Property") which is situated 170km northeast of Val d'Or, Quebec. Assays have been received for four of the eight drill holes with assays pending at this time. The highlight of these four holes was BA-11-29. This is arguably the best drill hole BonTerra has drilled to date. Within this drill hole are two distinct veins with numerous specks of visible gold observed in the geological log. These samples assayed 114.0 and 129.0 g/t gold. Descriptions of the continued success of BonTerra's ongoing drill program are outlined below and in table 1. Table 2 details the locations of the four drill holes disclosed in this news release.

Primary Drill Intercepts of BA-11-29

  * 15.30 metres assaying 14.85 g/t gold
  * INCLUDING: 11.30 metres assaying 20.10 g/t gold
  * INCLUDING: 5.3 metres assaying 41.55 g/t gold
  * INCLUDING: 2.5 metres assaying 88.10 g/t gold
  * INCLUDING: 0.70 metres assaying 129.00 g/t gold
  * INCLUDING: 0.70 metres assaying 114.00 g/t gold

Primary Drill Intercepts of BA-11-26

  * 25.50 metres assaying 1.19 g/t gold
  * INCLUDING: 5.30 metres assaying 5.43 g/t gold
  * INCLUDING: 2.60 metres assaying 10.19 g/t gold
  * INCLUDING: 0.60 metres assaying 38.80 g/t gold

Primary Drill Intercepts of BA-11-25

  * Several samples from the mineralized vein systems were drilled and
    are shown in table 1 below.

BA-11-10A

  * This  drill hole  was abandoned  at 99.61 metres  due to  difficult
    drilling conditions.  The drill hole was re-drilled  approximately four
    metres to the northeast  and  named  BA-11-10. BA-11-10 hit  multiple
    high grade zones at depth as disclosed in a news release dated
    August 8, 2011.

Mitchell Adam, President states, "We have intercepted numerous high grade zones with two samples assaying over 100 grams/tonne gold. It is becoming clear that with a greater understanding of the property our geological team continues hitting the targets. Once all of these holes are completed and assays received BonTerra intends to release our gold resource calculation for the Property."

Geological Characteristics ofthe Gold Bearing Veins on the Eastern Extension

The target for all drilling on the Eastern Extension property is smoky quartz veins mineralized with sulphides (pyrite, pyrrhotite, chalcopyrite, sphalerite ± visible gold). Sulphides commonly compose 1-10% of the mineralized zones and can be as high as 50% locally. Alteration is most commonly silica, carbonate, chlorite, tourmaline and sericite. The combination of quartz veins, tourmaline, alteration types and sulphides is ideal for gold mineralization in the area. Sphalerite present in the quartz veins appears to be associated with the highest grade gold zones on the property to date.

Qualified Person

This technical content of this press release has been reviewed and accepted by Thomas Clarke, Pr.Sci.Nat., a Director of BonTerra. Mr. Clarke is a Qualified Person under NI 43-101.

The drill program and sampling is being supervised on behalf of the Company by Geologica Inc. of Val d'Or, Quebec. These are sample results, taken from mineralized intervals of the drill holes. Depths and lengths are core lengths and not true widths. Gold intercepts disclosed in this news release are significant gold intercepts and not all the samples submitted for fire assay. Samples were submitted to ALS Chemex of Val d'Or, Quebec for crushing, pulverizing and fire- assay for gold. Samples fire-assaying greater than 10 grams per tonne gold are then fire-assayed with a gravimetric finish. Assay samples are taken from drill core, sawed in half along the core axis. One half is sent to ALS Chemex Laboratories and the other half retained by the Company for future reference. The Company applies a full quality assurance and quality control program (QAQC) system for every batch of samples submitted to the lab (gold standard, sample duplicate and blank).
