Vancouver, BC - August 11, 2011: BonTerra Resources Inc. (TSX.V: BTR; FSE: 9BR) (the "Company", "BonTerra") has retained Fugro Airborne Surveys to conduct an aeromagnetic survey over the entire Symphony Property ("the Property"). The Property is situated in the Omineca mining division approximately 29 kilometres southwest of Houston, British Columbia. The Symphony property is accessed by a well-maintained forestry road that is situated just east of Owen Lake. The Property comprises one contiguous block of claims totaling 2975 hectares. BonTerra recently staked additional claims to consolidate its land position situated in between the Silver Queen Mine to the south and the Silver Streak property to the north.

Directly bordering the Property to the south is the past producing Silver Queen Mine. Historical ore grades are 8.72 opt (299 grams / tonne) silver, 0.18 opt (6.17 g/t) gold, 6.73% zinc, 1.16% lead, and 0.47% copper.

The Silver Queen property is currently being advanced by New Nadina Explorations. New Nadina has intersected silver, gold and base metal mineralization on the property. They have completed an aeromagnetic and ZTEM survey, a titan geophysical survey and diamond drilling. Drilling revealed grades of up to 493.5 g/t silver, 5.06 g/t gold, 13.5% zinc, 6% lead and 2.88% copper. The mineralized trend has a general southeast to northwest trend, the direction towards which BonTerra's Symphony property is situated.

The Silver Streak property is situated to the north of the Symphony property. Trenching on the Silver Streak identified significant mineralization which included 1.99% Cu and 338 g/t Ag over 33 meters. An inclined diamond drill hole was drilled underneath this trench in 1991. A zone grading 8.8 meters of 0.49% copper and 258 g/t silver, within 21.1 meters averaging 0.27% copper and 127 g/t silver was discovered. Another trench excavated in 2002 graded 0.26% copper and 1.91 g/t Ag over 16.7 meters. The mineralized zone is believed to have a NW-SE strike, the general direction of BonTerra's Symphony property.

BonTerra's airborne survey will be flown in late August to early September. This survey will total 308 line kilometres of magnetic readings. The Company plans on using this survey to identify additional targets of interest on the property in its evaluation for silver and base metal mineralization potential on the Property.

Mitchell Adam, President, states, "With the Silver Queen Mine to the south and the Silver Streak property to the north, BonTerra has made the decision to fly the aeromagnetic survey on the Symphony property in BC. As silver is currently trading at around $40 an ounce, the strategic location of the Symphony property is of great interest to us. BonTerra also fully committed and continues to drill our Eastern Extension gold property in Quebec which hosts significant gold mineralization with grades up to 114 g/t. BonTerra has recently discovered a 169.70 metre intercept grading 0.73 g/t gold. Set within this are high grade intervals assaying up to 54 g/t. We are very excited to be working towards an inferred resource calculation. We firmly believe that BonTerra is extremely well positioned to take advantage of bullish markets in both gold and silver."
