Val-d'Or, Quebec--(Newsfile Corp. - December 12, 2022) -
Bonterra Resources Inc. (TSXV: BTR)
(OTCQX: BONXF) (FSE: 9BR2)
("
Bonterra
" or the "
Company
") is pleased to announce more results
from the ongoing infill drilling campaign at the Barry underground project. The Company commenced a
125,000 metres ("
m
") drill program at the Barry underground deposit last August, which contains 0.5
million ounces of Measured and Indicated Mineral resources and 0.7 million ounces of Inferred Mineral
resources, as stated in the last mineral resource estimate (the "
2021 MRE
", see press release dated
June 23, 2021).
To date, 21,800 m (51 holes) of infill drilling has been completed from the surface,
mainly in the upper half of the Barry underground deposit. Since the previous release dated November
15, 2022, assays from 11 holes have been received. Highlights from these assays are presented in the
present release.
Highlights include:
21.9 g/t Au over 4.4 m, including 158.5 g/t Au over 0.5 m in hole MB-22-541
7.5 g/t Au over 2.8 m, including 30.3 g/t Au over 0.6 m in hole MB-22-542
13.0 g/t Au over 3.7 m, including 49.7 g/t Au over 0.5 m and 6.7 g/t Au over 3.9 m, including 27.2
g/t Au over 0.7 m and 4.3 g/t Au over 5.8 m, including 24.2 g/t Au over 0.5 m in hole MB-22-547A
8.1 g/t Au over 4.0 m, including 44.5 g/t Au over 0.7 m in hole MB-22-548
Marc André Pelletier, President and CEO, commented: "The ongoing infill drill program at Barry is
focused on the upper half of the underground deposit and continues to deliver high-grade results. It is
common to intercept more than one lens of mineralization in a single drill hole at Barry. For example,
numerous high-grade intercepts are reported across six different lenses in drill hole MB 22-547A;
highlighted by 13.0 g/t Au over 3.7 m in lens AB17; 6.7 g/t Au over 3.9 m in lens 800; and 4.3 g/t Au over
and 5.8 m in lens H11. The Company intends to continue infill drilling the Barry deposit next year with two
diamond drills on surface at a rate of approximately 6,000 m per month."

The ongoing infill drill program of the Barry underground project is designed to convert the Inferred
resources from the 2021 MRE into Indicated resources by decreasing the drill spacing to 25 m. The
program especially aims to delineate and expand high-grade mineralized shoots identified in the 2021
MRE. Results from recent assays, including those in this press release, underscore the economic
potential of the underground mineralization with high-grade intersections between 100 m and 300 m
below surface in well know mineralized lenses. For example, MB-22-541 reported 21.9 g/t Au over 4.4
m, including 158.5 g/t Au over 0.5 m in H8 Zone, 200 m below surface; MB-22-548 returned 8.1 g/t Au
over 4.0 m, including 44.5 g/t Au over 0.7 m from the H3 Zone, 300 m below the surface; MB-22-547A
returned 4.3 g/t Au over 5.8 m, including 24.2 g/t Au over 0.5 m from H11 Zone, 350 m below surface;
13.0 g/t over 3.7 m, including 49.7 g/t Au over 0.5 m 100 m below the surface from AB 17 Zone; and
lastly MB-542 reported 7.5 g/t Au over 2.8 m, 100 m below the surface from the AB 01 Zone. These
strong intercepts as well as certain intercepts highlighted in press releases throughout 2022 are shown
on Figure 2.

The sub-vertical 800 Zone and its surrounding H-series zones continue to provide high-grade drilling
results as highlighted by hole MB-22-547A returning 6.7 g/t Au over 3.9 m, including 27.2 g/t Au over 0.7
m and hole MB-22-542 returning 2.6 g/t Au over 4.2, including 14.5 g/t Au over 0.5 m (Figures 3 and 4).

Barry Deposit Geology
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 at 50-65 degrees
along the lower and upper contacts of the D1, D2 and D3 felsic intrusions with mafic volcanics. Gold
mineralization is associated with disseminated sulfides within shear zones and veins with local visible
gold. The Barry deposit has been delineated over 1.4 kilometres 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 the Company's Bachelor Mine analytical
laboratory (the "
Laboratory
") and at AGAT Laboratories in Val d'Or.
The Company employs 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 AGAT laboratories.
Blanks, duplicates, and certified reference standards are
inserted into the sample stream to monitor the Laboratory's performance.
The Company's QA-QC
program requires that at least 10% 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
verifications show a high degree of correlation with the Laboratory's results.

Cautionary and Forward-Looking Statements
Caution regarding forward-looking statements
This press release contains "forward-looking information" that is based on Bonterra's current expectations, estimates, forecasts and projections.
This forward-looking information includes, among other things, statements with respect to Bonterra's exploration and development plans and placing
the Bachelor-Moroy deposit under long-term care and maintenance. The words "will", "anticipated", "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 resources. 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
characteristics 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 uncertain 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, performance or achievements to be materially different from those expressed or
implied by such forward-looking information. Such factors include but are not limited to: uncertainties related exploration and development; 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 encountered in connection with
exploration activities; and labour relations matters. This list is not exhaustive of the factors that may affect our forward-looking information. These
and other factors should be considered carefully, and readers should not place undue reliance on such forward-looking information.
