(“
Bonterra

is pleased to announce
more
results from the
now
completed
infill
and expansion drilling
campaign at the Barry
underground
project
,
which holds
0.5 million ounces of Measured and
Indicated Mineral resources and 0.7 million ounces of Inferred
Mineral resources according to the last mineral resources estimate (the “
2021 MRE
”, see press
release dated June 23, 2021)
.
The primary goal of this
campaign was to convert mineral resources
to
a higher confidence category and enhance the interpretation and grade continuity of the
mineralization
, primarily
in the upper section of the deposit.
In total,
31
,
349
metres (“

(
91
holes) of infill drilling
has been completed from surface
since
August
2022

The infill drill program
at
the Barry underground
project
was designed to convert the Inferred
resources from the 2021 MRE into Indicated resources by decreasing the drill spacing to 25 m and
to expand the mineralization in the sub

one at depth. The results presented in this
release demonstrate the
predictability of the 800 Zone geology model and highlight that the
mineralization remains open at depth, following the well

eology
The Barry gold deposit is characterized by three dominant sets of structures, all dipping to the
southeast. The sub
-
vertical shear zones and the H
-
Series shear zones dipping 25 to 40 degrees are
hosted within intermediate to
mafic volcanics and tuffs with local felsic intrusions. Contact zones
dip
from
50
to
65 degrees along the lower and upper contacts of the D1, D2 and D3 felsic intrusions
with mafic volcanics. Gold mineralization is associated with disseminated sul
ph
ides w
ithin shear
zones and veins with local visible gold. The Barry deposit has been delineated over 1.4 k
m
along
strike and 700 m
below surface
and remains open for expansion.

Quality Control and Reporting Protocols
The Barry project’s drill core gold analyses are performed at Bachelor Mine
Lab
ora
t
ory
, Actlabs
(Ste
-
Germaine
-
Boulé)
and at AGAT Laboratories
located in
Val d’Or
, Quebec
. The Company
’s
laboratory
and
external
laboratories
employ a rigorous QA
-
QC analysis program that meets
industry standards. The analyses are carried out by fire
assay (A.A.) with atomic absorption finish
at Bachelor Mine Laboratory and with gravimetric finish for assay above 10 g/t Au at
Actlabs
and
AGAT
laboratories. Blanks, duplicates, and certified reference standards are inserted into the
sample stream to mon
itor the Laboratory’s performance. The Company's QA
-
QC program
requires that at least
5
% of samples be analyzed by an independent laboratory. These verification
samples are sent to ALS Minerals laboratory facility located in Val
-
d'Or, Quebec. The
verifi
cations show a high degree of correlation with the Laboratory’s results.

This press release contains “forward

forecasts,
and projections. This forward

looking information includes, among other things, statements with respect to
Bonterra’s exploration and development plans
and placing the

care and

. The words “will”, “anticip

“plans” or other similar words and phrases are intended to identify
forward
-
looking information. This forward
-
looking information
includes namely
information with respect to the
planned exploration programs and the potential growth in mineral resour
ces. Exploration results that include drill
results on wide spacings may not be indicative of the occurrence of a mineral deposit and such results do not provide
assurance that further work will establish sufficient grade, continuity, metallurgical
charact
eristics,
and economic
potential to be classed as a category of mineral resource. The potential quantities and grades of drilling targets are
conceptual in nature and, there has been insufficient exploration to define a mineral resource, and it is uncertai
n if
further exploration will result in the targets being delineated as mineral resources. Forward
-
looking information is
subject to known and unknown risks, uncertainties and other factors that may cause Bonterra’s actual results, level of
activity,
perfo
rmance,
or achievements to be materially different from those expressed or implied by such forward

the ability to raise sufficient capital
to fund exploration and development; changes in economic conditions or financial
markets, environmental and other judicial, regulatory,
political,
and competitive developments; technological or
operational difficulties or inability to obtain permits encoun
