Bonterra Improves Mineralized Continuity and Expands Gold
Bearing Structure to the East at Barry
Val-d’Or, QC – March 1, 2021 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF,
FSE: 9BR2) (“Bonterra” or the “ Company”) is pleased to announce an update on results from
the ongoing drilling campaign at the Barry project. These resu lts encompass 16 diamond drill
holes for 6,322 metres (“m”), of which seven holes were infill and nine holes were expansion. The
Company is currently drilling at a rate of approximately 10,000 m per month and plans a mineral
resource estimate update for Q2/21 (“2021 Resource Update”), which is expected to incorporate
approximately 130,000 m of new dr illing information. In additi on, work on the the Preliminary
Economic Assessment (“PEA”) is currently underway and is expected to be completed in the fall
of 2021.
Highlights:
Expansion Drilling:
6.1 g/t Au over 4.3 m and 3.2 g/t Au over 6.9 m in hole MB-21-330
6.7 g/t Au over 0.5 m in hole MB-20-321
6.1 g/t Au over 1.0 m in hole MB-20-328
Infill Drilling:
5.5 g/t Au over 3.6 m and 5.8 g/t Au over 0.6 m in hole MB-20-318
5.1 g/t Au over 4.8 m and 1.8 g/t Au over 6.0 m in hole MB-20-323
15.1 g/t Au over 1.0 m in hole MB-20-326
Pascal Hamelin, CEO commented: “The results from infill drillin g on the northern upper portion
of the Barry deposit and expansi on drilling at the eastern exte nsion are very promising.
Specifically, the infill drilling confirms mineralized continui ty of the existing inferred resources
closer to surface and drilling of the eastern extension is expe cted to add new resources at depth.
Drilling data from the Company’s three main deposits totaling a pproximately 130,000 m will be
incorporated into the upcoming 2021 Resource Update expected in Q2/21. The 2021 Resource
Update will in turn provide the foundation of a PEA planned for the fall of 2021. Additionally,
the Company is about two-thirds of the way through the permitting process to expand the milling
rate at the Company’s 100% owned Bachelor Mill from 800 to 2,400 tonnes per day.”
The Company has drilled 66 holes representing a total of 23,830 m at Barry since July 23, 2020.
Results from 16 holes have been received since the press release dated December 21, 2020. Results
from the remaining 17 drilled holes are pending. (See Table 1 and Figures 1 and 2).
SLR Consulting (Canada) Ltd. has been contracted to prepare the 2021 Resource Update and a
PEA currently underway in collaboration with Bonterra’s geological team on the Moroy, Gladiator
and Barry projects scheduled to be completed in the fall of 202 1. SGS Geological Services has
been selected to undertake a peer review of the 2021 Resource U pdate and PEA preparation
process. The Company expects thes e initiatives to help demonstr ate the value of the Company’s
assets.

The Barry gold deposit is characterized as multiple sub-paralle l, sub-vertical, shear zones and a
second set of veins dipping 50 to 60 degrees to the south hoste d within intermediate to mafic
volcanics and tuffs with local felsic intrusions. Gold mineral ization consists of disseminated
sulfides within the shear zones and the veins with local visibl e gold. The Barry deposit has been
delineated over 1 kilometer along strike and 600 m vertical and remains open for expansion.
Due to an accumulated backlog at the Company’s laboratory, assaying priority has been assigned
to drill hole samples directly affected within the 2021 Resource Update. Pending assays of samples
awaiting analysis from drilling beyond the project models not i ncluded in the 2021 Resource
Update are to be processed by Activation Laboratories Ltd. (" Actlabs"), based in northwestern
Quebec.

Notes:
1) The meterage represents the length of the drilled lengths.
2) True widths are estimated to be greater than 85% of the dril l intersection length.
3) The mineralized intervals s hown above use a 0.5 g/t Au cut-off grade.
Twelve infill-holes were dril led (MB-20-314 to 319; MB-20-324 t o 328 and MB-20-330) and
confirm mineral continuity within the 2019 Barry inferred resource, seven of which have returned

significant values. Eight holes were drilled along the east ex tension of the current 2019 Barry
resource.
The following holes have returned significant grades in this se ctor; MB-20-330: 3.2 g/t Au over
6.9 m in the 850 Zone and 6.1 g/t Au over 4.3 m in the 1000 Zon e; MB-20-323: 5.1 g/t Au over
4.8 m in the 850 Zone and 1.8 g/t Au over 6.0 m in the H13 zone ; MB-20-331: 6.1 g/t Au over
0.5 m in the 850 Zone. (See Table 1 and Figures 1 and 2).

About Bonterra Resources Inc.
Bonterra is a Canadian gold exploration company with a large po rtfolio of advanced exploration
assets anchored by a central milling facility in Quebec, Canada . The Company has three main
assets, Gladiator, Barry, and Moroy, that collectively have a t otal of 698 thousand ounces in
measured & indicated categories, and 1.4 million ounces in infe rred category. Approximately
130,000 m of drilling will be used to update this resource shortly. Importantly, the Company owns
the only permitted and operational gold mill in the region that is currently two-thirds the way
through the permitting process to expand from 800 to 2,400 tonn es-per-day. Bonterra is focused
on graduating from advanced exploration to a development company over the next 18-months to
deliver shareholder value.
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 sta ndards. The analyses are carrie d out by fire assay (A.A.) with
atomic absorption finish. Blanks, duplicates, and certified reference standards are inserted into the
sample stream to monitor the Laboratory’s performance. The Com pany'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 V a l - d ' O r , Q u e b e c . T h e
verifications show a high degree of correlation with the Labora tory’s results. Pending assays of
samples awaiting analysis from drilling beyond the project mode ls not included in the 2021
Resource Update are to be processed at Actlabs, based in northwestern Quebec.

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 includes, among other things, statements with respect to
Bonterra’s exploration and develo pment plans. The words “will”, “anticipated”, “plans” or other similar words and
phrases are intended to identify forward-looking information. T his forward-looking information includes namely,
information with respect to the planned exploration programs an d 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 clas sed 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, perform ance 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 market s, environmental and other judicial, regulatory,
political and competitive developments; technological or operat ional difficulties or inability to obtain permits
encountered in connection with exploration activities; and labo ur 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.
