BonTerra Assays 73.82 g/t Gold Over 3.0 Metres at the New Rivage Zone on the Eastern Extension Property, Quebec

VANCOUVER, BRITISH COLUMBIA -- (Marketwire - May 10, 2012) - BonTerra Resources Inc. (TSX VENTURE:BTR) (FRANKFURT:9BR) (the "Company" or "BonTerra") has received exciting high grade gold assays for hole BA-12-10 ("Hole 10"), the first drill hole BonTerra drilled into the Rivage Zone ("Rivage") on its Eastern Extension property (the "Property") which is located approximately 170 km northeast of Val d'Or, Quebec. Hole 10 has surpassed BonTerra's expectations and assayed 73.82 g/t gold over 3.00 metres. The highest grade sample received from this drill hole was 220.00 g/t gold (6.41 Ounces per short ton) in a one metre long drill core sample. This is the highest grade drill core sample BonTerra has received since commencing work on the Property in the fall of 2010. Significant drill results are shown in table 1 with the collar details shown in table 2.

Hole 10 was collared approximately 120 metres from the Rivage outcrop and assayed 204 g/t gold in a chip sample. BonTerra also intercepted bonanza gold grades in a smoked, altered and mineralized quartz-carbonate vein. To view a photograph of this mineralized high grade gold vein taken by Robert Gagnon on March 21, 2012, click on the following link: http://www.bonterraresources.com/i/photos/BA-12-10-Long-View.jpg. Management believes this demonstrates a potential continuity of the Rivage. This potential continuity, on top of hitting the target at depth, led BonTerra to drill an additional four (4) holes into the Rivage.

Thomas Clarke, Director states "BonTerra is encouraged by the Rivage Zone drill results, the assay of 220 g/t gold and the interception of a new vein on the Property. The discovery of somewhat coarse visible gold at depth was the strongest factor motivating us to drill four additional holes averaging 420 metres in depth into the target before receiving assays for BA-12-10. The area from the Rivage northeast across Lac Barry to the primary drilling area and eastwards further still appears to be one large target. BonTerra has confidence in the high caliber of the Urban-Barry gold camp."


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. Sample preparation and analysis is discussed below.

These sample results disclosed aboved are taken from mineralized intervals of the drill holes. Depths and lengths are core lengths and are not true widths and possibly down dip at times or otherwise non perpendicular. The gold intercepts disclosed in this news release are significant gold intercepts and not all the samples were submitted for fire assay. Samples were submitted to AGAT Laboratories ("AGAT") in Sudbury, Ontario for crushing, and pulverizing. AGAT is independent of the Company and is certified by the Standards Council of Canada (Accredited laboratory 665). The samples crushed to 75% passing 2 mm and split to 250 grams. The crushed sample is then pulverized to 85% passing 75 um. Once the sample preparation is complete they are shipped to AGAT's head office in Mississauga, Ontario for analysis. Fifty gram samples are fire assayed with ICP finish. All samples assaying greater than 10 g/t gold are then re-assayed with a gravimetric finish and by metallic screen with a fire assay finish. Assay samples are taken from drill core, sawed in half along the core axis. One half is sent to AGAT and the other half retained by the Company for future reference. BonTerra retains coarse rejects and pulps in a secure facility. The Company applies a full quality assurance and quality control program (QAQC) system for every batch of samples submitted to the lab (gold standard, field sample duplicate and blank).
