Vancouver, BC - June 2, 2011: BonTerra Resources Inc. (TSX.V: BTR; FSE:
9BR)
(the 'Company', 'BonTerra') is in receipt of gold assays for an additional
four
(4) drill holes on the Eastern Extension Gold Project ('the Property').
Hole BA-
11-23 assayed 8.95 grams/tonne ('g/t') gold (0.26 Oz/ton) over 6.2 metres
(20.46
Feet). Gold is concentrated in mineralized and altered quartz veins.
Visible
gold was observed in two samples in BA-11-23. The highest grade sample in
this
hole assayed 42.6 g/t and corresponded to a sample with fifteen (15)
visible
gold specks. Significant gold values are shown in table 1 below.

Mitchell Adam, President, states, 'BonTerra is pleased to see the gold
zones be
proven larger with additional drilling. Intercepting veins bearing visible
gold
is rewarding and a result of the hard work by our geological team.
BonTerra
continues drilling with the intent of conducting the first ever NI
43-101
compliant resource calculation on the property.'

The Company has drilled 32 holes on this property to date and is awaiting
assays
from three (3) additional holes drilled to expand the peninsula zone
to the
west. This zone assayed 14.00 metres of 8.01 g/t gold (0.23 Oz/ton)
including
3.33 metres of 27.60 g/t (0.81 Oz/ton) in BA-11-05 as reported on
February
17, 2011.

Qualified Person
This press release has been reviewed by Thomas Clarke, Pr.Sci.Nat., and a
Director of BonTerra. Mr. Clarke is a Qualified Person under NI 43-101.

The drill program and sampling is being supervised on behalf of the Company
by
Geologica Inc. of Val d'Or, Quebec. These are sample results, taken from
mineralized zones of the drill hole. Depths and lengths are core lengths
and not
true widths. Samples were submitted to ALS Chemex of Val d'Or, Quebec for
crushing, pulverizing and fire-assay for gold. Samples fire-assaying
greater
than 10 grams per tonne gold are then fire-assayed with a gravimetric
finish.
Assay samples are taken from drill core, sawed in half along the core axis;
one
half is sent to ALS Chemex Laboratories and the other half retained for
future
reference. The Company applies a full quality assurance and quality control
(QAQC) system for every batch of samples submitted to the lab. The QAQC
samples
include a standard, duplicate and blank.
