Bonterra Discovers New Gold Zone Near Surface within

Two Kilometres of the Bachelor Mill

Val-d’Or, QC – March 22, 2021 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF,

FSE: 9BR2) (“Bonterra” or the “Company”) is pleased to announce the discovery of a new near

surface zone of gold mineralization found within the Company’s Bachelor-Desmaraisville land

package. Drilling encountered a broad zone of mineralization t hat is located close to surface and

within two kilometres of the Company’s 100% owned Bachelor Mill. The newly discovered zone

of mineralization is proximal to the syenite intrusion shown in Figure 2. Results to date indicate

that the mineralized zone is open in all directions. The Company plans to mobilize a drill crew as

soon as possible to begin follow-up work.

Highlights:

 24.85 metres (“m”) of 1.4 grams-per-tonne gold (“g/t Au”); including 4.25 m of 3.6 g/t Au

(EB20-008);

 18.3 m of 0.9 g/t Au; including 10.5 m of 1.3 g/t Au (EB21-021); and

 Both results occur within 50 m of surface and the mineralization is open in all directions.

Pascal Hamelin, CEO commented: “This newly discovered near-surf ace mineralized target is

extremely exciting for Bonterra. The new gold target has the potential to rapidly grow due to the

widths and ease in which short holes from surface can be used to define the target boundaries. To

find something this close to the Bachelor mill demonstrates the untapped potential of this mining

camp. We continue to believe this camp is largely underexplore d and that there will be several

new discoveries in the region in the near future. In addition, the discovery’s proximity to our

existing mill infrastructure is also important as it lowers the hurdle to becoming a potential source

of mill feed. As a result of this success, we plan on mobilizing a drill crew as soon as possible to

do immediate follow-up work on near-surface targets.”

Notes:

1) The meterage represents the length of the drilled lengths.

2) True widths are estimated to be greater than 50% of the dril l intersection length.

3) The mineralized intervals s hown above use a 0.5 g/t Au cut-off grade.

4) Gold results obtained between 0.1 and 0.5 g/t Au are represented as anomalous values

5) Gold results obtained below <0 .1 g/t Au are represented as no significant values

Exploration drilling results are c onfirming the existence of go ld mineralization within sheared

meta-volcanoclastic and meta-se dimentary rocks hosting quartz ( +/- carbonate-ankerite-pyrite)

veining and related vein stockworks. Results from the recent d rilling fence across the east flank

of the O’Brien intrusive stock of syenitic composition is supporting the existence of a broad gold

mineralized vein system at shallow depths proximal to the mine area.

Drilling of the other regional ex ploration targets: Clone, Sigmoid and Deer have so far, returned

anomalous gold values. These early, first pass drilling result s are key for exploring the potential

for gold mineralization of the relatively untested targets within the mining camp (See Figure 1).

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 metres 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 Desmaraisville area’s drill core gold analyses are performed at the 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.

Qualified person

Francis Lefebvre, P.Geo and Project Manager at Moroy supervises all exploration activities on the

Moroy project. Mr. Lefebvre is a Qualified Person as defined by National Instrument 43-101

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

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
