Bonterra Intersects 7.1 g/t Au over 7.6 m, Including 20.1 g/t over 1.4 m
and 13.2 g/t over 1.4 m, and Extends the Near Surface Mineralization by
200 m to the Northeast of the Barry Gold Deposit
Val-d’Or, QC – April 7, 2022 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE:
9BR2) ( “Bonterra” or the “ Company”) is pleased to announce re sults from the ongoing drilling
campaign at the Barry project. Recent drilling results expand upon the northeast sector of the Barry
deposit near surface and the southwest sector at depth. The latest results obtained from 43 diamond drill
holes are designed to increase the 2021 mineral resource estimate (“2021 MRE”) (see press release dated
June 23, 2021). Drilling highlights include 7.1 grams-per-ton gold (“g/t Au”) over 7.6 metres (“m”) in
the near-surface zone AB08, approximately 200 m northeast of the previously released intercept 8.0 g/t
Au over 7.6 m (see press release dated October 5, 2021).
The Company is currently drilling at a rate of approximately 7, 500 m per month, focused mainly on
expanding its Barry and Gladiator gold deposits highlighted within the recently released 2021 MREs.
Highlights include:
7.1 g/t Au over 7.6 m, including 20.1 g/t Au over 1.4 m and 13. 2 g/t Au over 1.4 m in hole MB-
21-417
1.3 g/t Au over 12.0 m, including 3.0 g/t Au over 4.8 m in hole MB-21-404
2.3 g/t Au over 9.0 m, including 6.8 g/t Au over 2.6 m in hole MB-21-409
17.4 g/t Au over 4.4 m, including 146.0 g/t Au over 0.5 m in hole MB-21-410
10.8 g/t Au over 5.1 m, including 23.1 g/t Au over 1.4 m in hole MB-22-416
12.1 g/t Au over 6.1 m, including 73.5 g/t Au over 0.5 m in hole MB-22-420
Marc André Pelletier, President and CEO commented: “These recent drill results confirm the extension
of the mineralization near surface and at depth at Barry, extending the existing mineral resource by over
200 m to the northeast from the resource pit shell, and up to 5 0 m to the southwest of the underground
resource. The continuation of the H12 zone and the discovery of new H series at depth demonstrate the
potential to add more ounces beyond the existing 2021 MRE.
Work is currently underway on a Preliminary Economic Assessment (“PEA”) based on the open pit
resources at Barry in the 2021 MRE. The PEA is projected to be completed in late Q2 2022 and is
expected to demonstrate the poten tial for restarting mining ope rations in the near term. The Company
will soon undertake infill and definition drilling on the under ground portion of the d eposit to better
understand the potential of an underground mining scenario.
At present, exploration activitie s a t B a r r y i n c l u d e o n e d r i l l rig drilling an additional 400 m to the
northeast of the existing open p it resources and a second drill on regional exploration targets,
approximately 5 kilometers to the northeast of the Barry deposit.
At the Bachelor Mine Complex, the permitting process for the mi ll and tailings management area
expansion is ongoing, and the Company expects to provide additi onal information by mid-year with a
COMEX permit expected by end of 2022 and provincial permits thereafter.”

The Barry drilling campaign is currently focused on the expansion of key gold mineralized northeast of
the 2021 MRE. Multiple diamond drill holes have been designed to confirm the open pit extension
potential to the northeast. Several drill holes have confirmed the extension of the mineralization near
surface with large intercepts grading above the open pit resource cut-off grade (1.0 g/t Au). Specifically,
hole MB-21-417 extended the near surface mineralization by 200 m with 7.1 g/t Au over 7.6 m, including
20.1 g/t Au over 1.4 m and 13.2 g/t Au over 1.4 m in the AB08 zone and 3.9 g/t Au over 6.3 m, including
10.1 g/t Au over 2.0 m in a new H series zone (figure 2).

Expansion drilling has also confir med the mineral continuity an d expansion of several known H-Type
zones, particularly the H12 zone with holes MB-22-420 and MB-22-416, which respectively intersected
12.1 g/t Au over 6.1 m, including 73.5 g/t Au over 0.5 m and 10.8 g/t Au over 5.1 m, including 23.1 g/t
Au over 1.4m, expanding the mineralization by 75 m at depth and 50 m to the southwest beyond the
2021 MRE (figure 3).

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 dippi ng 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 7 00 m vertical and
remains open for expansion.

Notes:
1) The meterage represents the length of the drilled lengths.
2) Mineralized host rock adjacent to vein material with anomalous values are included in reported intervals.
3) True widths are estimated to be greater than 70% of the drill intersection length.
4) The shown mineralized intervals listed are above 0.5 g/t Au.
5) Gold results obtained between 0.1 and 0.5 g/t Au are represented as anomalous values.
6) Gold results obtained below 0.1 g/t Au are represented as no significant values.
Quality Control and Reporting Protocols
The Barry project’s drill core gold analyses are performed at t he Company’s Bachelor Mine analytical
laboratory (the “Laboratory”). The Company employs a rigorous QA-QC analysis program that meets
industry standards. The analyses are conducted by fire assay (A .A.) with atomic absorption finish.
Blanks, duplicates, and certified reference standards are inser ted into the sample stream to monitor the
- 8 -
Laboratory’s performance. The C ompany'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
This press release contains “forward-looking information” that is based on Bonterra’s current expectations, estimates,
forecasts, and projections. This forward-looking information in cludes, among other things, statements with respect to
Bonterra’s exploration and development plans. The words “will”, “anticipated”, “plans” or other similar words and phrases
are intended to identify forward-looking information. This forw ard-looking information includes namely information with
respect to the planned exploration programs and the potential g rowth in mineral resources. Exploration results that include
drill results on wide spacings may not be indicative of the occ urrence 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 res ult
in the targets being delineated as mineral resources. Forward-l ooking 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 fo rward-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 market s, environmental and other judicial, regulatory, political,
and competitive developments; technological or operational diff iculties 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.
