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.'
