BonTerra Awaits Assays for Three Holes from the Eastern Extension Property, Quebec

VANCOUVER, BRITISH COLUMBIA--(Marketwired - June 12, 2013) - BonTerra Resources Inc. (TSX VENTURE:BTR)(FRANKFURT:9BR) (the "Company" or "BonTerra") has submitted samples from three drill holes to ALS Laboratories ("ALS") in Val d'Or, Quebec from the Company's flagship Eastern Extension Property (the "Property"). Two of these three holes were drilled into the Peninsula Zone to test continuity of veins hosting high grade nearby while the final hole was drilled at the Rivage Zone.

When examining the core, particularly for holes BA-12-07 ("Hole 7") and BA-12-09 ("Hole 9"), mineralized quartz-tourmaline veins were observed and sampled. Hole 7 is the westernmost hole BonTerra has drilled on the Peninsula Zone to date. It must be noted that the veins seen in holes 7 and 9 appear to line up with nearby veins which have been discovered in previous drill holes by BonTerra. One of the key targets for both Holes 7 and 9 is a vein regularly returning high grade gold values. This vein has been intercepted in four previously completed drill holes: 42.60 g/t over 1.30 metres (BA-11-23); 10.19 g/t over 2.60 metres (BA-11-26); 25.40 g/t over 1.00 metre (BA-11-31) and 10.00 g/t over 0.90 metres (BA-11-36W).

Nav Dhaliwal, President & Director states, "It is BonTerra's goal in 2013 to focus the Company's work on growing BonTerra's gold resource as well as the overall footprint of the deposit. Strategically placed drill holes will aid the Company in doing just this. The veins, sulphide mineralization and alteration observed in these drill holes were very encouraging and we look forward to receiving the assay results."

The sample results disclosed above 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. Samples of these mineralized intervals were clearly marked, normally one metre in length. Assay samples are taken from drill core, sawed in half along the core axis. One half is sent to ALS 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). Samples were sawed in the field at the Bonterra exploration camp, labeled and put in clearly marked sample bags. Once this was complete the samples were submitted to ALS for crushing, and pulverizing. ALS is independent of the Company and is certified by the Standards Council of Canada. The samples crushed to 70% passing 2 mm and split to 1 kg. The crushed sample is then pulverized to 85% passing 75 mm. Fifty gram samples are fire assayed with an AAS 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.
