BonTerra Completes Drilling the First 10,000 Metres & 40 Drill Holes on the Eastern Extension Property, Quebec

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 4, 2011) - BonTerra Resources Inc. (TSX VENTURE:BTR) (FRANKFURT:9BR) (the "Company", "BonTerra") has completed drilling forty (40) diamond drill holes on the Eastern Extension (the "Property") totaling 10,112 metres. This drill program commenced in October 2010 and has continued into July of this year. Over the past year, BonTerra has submitted a total of approximately 4,300 samples to ALS Chemex of Val d'Or, Quebec to be assayed for gold. BonTerra currently awaits gold assays for approximately 1,450 of these samples. An updated drill map can be accessed by clicking on the link near the base of this news release.

Of great interest to the Company is BA-11-29. This hole was deepened after intersecting a mineralized vein zone at the base of the hole assaying 8.1 metres of 14.17 grams/tonne ("g/t") gold including a high grade zone of 3.50 metres grading 32.74 g/t and the highest grade sample BonTerra has received to date, 0.70 metres at 114.0 g/t gold. The gold values in this paragraph were disclosed in a news release dated July 12, 2011. This intercept is open at depth and additional mineralized veins have been identified in the deepened part of this drill hole with assays pending. The Company also recently discovered a vein over 10 metres in width for the first time on the Property.

BonTerra is currently awaiting assays for eight (8) drill holes at this time as shown by both table 1 and by clinking on the link to the drill map below. All these drill holes intersected smoky quartz veins mineralized with sulphides. Visible gold present in smoky quartz veins has also been noted in the geological drill logs for five (5) of these drill holes. One of the eight (8) drill holes with assays pending has visible gold noted in six (6) distinct smoky quartz veins. These smoky quartz veins are the primary exploration target and host the vast majority of the high grade gold zones. The Company is currently prospecting using a beep mat to aid in finding near surface additional subcropping veins and drill targets on the Property.

Mitchell Adam, President, states, "Drilling approximately 10,000 metres is a significant milestone for BonTerra. In addition, the Company has sent over 4,000 samples to be assayed for gold. It demonstrates the high caliber of the Eastern Extension Property and the Urban-Barry belt. It also exhibits BonTerra's strong commitment to advancing this exciting gold property. We look forward to receiving additional assays and announcing our resource calculation for the Property later this year."
