Bonterra intersects 16.5 g/t Au over 2.7 m, including 29.5 g/t over 1.0 m
in a New Zone northeast of the Barry Gold Deposit
Val-d’Or, QC – September 08, 2021 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF,
FSE: 9BR2) (“Bonterra” or the “Company”) is pleased to announce results from the ongoing drilling
campaign at the Barry project. Recent drilling results expand upon the northeast sector of the Barry
deposit near surface and at depth (Figures 1 and 2). The latest results encompass 13 diamond drill holes
designed to expand the 2021 mineral resource estimate (“2021 MRE”) released in June (see press release
dated June 23, 2021). Drilling highlights include 16.5 g/t gra ms-per-tonne gold (“ g/t Au”) over 2.7
metres (“m”) in a new zone named H16, immediately northeast of the 2021 MRE.
The Company is currently drilling at a rate of approximately 6, 000 m per month, focused on its main
gold deposits to expand upon the recently released 2021 MREs. In addition, work on the preliminary
economic assessment (“PEA”), which would utilize the exis ting Bachelor Mill as a central processing
facility is ongoing and is expected to be completed in Q4 2021.
Highlights include:
16.5 g/t Au over 2.7 m, including 29.5 g/t over 1.0 m and 4.5 g/t over 2.0 m in MB-21-355
0.7 g/t Au over 55.0 m, including 7.5 g/t Au over 1.5 m and 3.6 g/t Au over 3.9 m in MB-21-359
16.0 g/t over 0.6 m and 12.6 g/t over 0.5 m in MB-21-368
5.9 g/t Au over 5.3 m, including 22.0 g/t over 0.9 m in MB-21-369
4.8 g/t over 2.0 m, including 18.4 g/t over 0.4 m in MB-21-376
Pascal Hamelin, CEO commented: “The results released today supp ort our view that substantial near
surface exploration potential exists at Barry. Recent explorat ion drilling hit both thick, continuous
mineralization at open pit depth and high-grade intervals withi n 200 m depth immediately adjacent of
the 2021 MRE. We look forward to receiving more diamond drill results from this area soon.”

The Barry drilling campaign is currently focused on the expansion of key gold mineralized zones around
the 2021 MRE. Multiple diamond drill holes tested open pit pot ential to the northeast of the open pit
resource shell in the 2021 MRE and followed up on deeper interc epts in hole MB-20-323 in the same
sector (see press release dated March 1, 2021). Near-surface mineralization above open pit cut-off grade
was intercepted up to 100 m north east of the existing pit shell (Table 1, Figures 2, 3 and 4).
Mineralization remains open to t he east. Drilling also confirm ed the presence of several H-type zones
north of the 1000 zone, returning high-grade intercepts at less than 200 m depth and laterally within 50
to 250 m of the existing resource along the 1000 zone (Table 1, Figures 2, 3 and 4). Follow-up drilling
on these very promising targets is expected to begin soon in or der to better define their geometries.
Several drill holes also continued to test extensions of the H series structures to the southwest, with
success along the H3 zone, outlining continued potential at depth (Table 1 and Figure 1).

Barry Deposit Geology
The Barry gold deposit is characterized by three dominant sets of structures, all dipping to the south-
east. The sub-vertical shear zone s and the H-Series shear zone s 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 wi thin shear zones and veins with local
visible gold. The Barry deposit has been delineated over 1.4 kilometres along strike and 700 m vertical
and remains open for expansion.

Notes:
1) The length represents the interval of the drilled core.
2) True widths are estimated to be greater than 55% of the drill intersection length.
3) The shown mineralized intervals listed are above 0.5 g/t Au.
4) 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 carried out 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
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 Val-d'Or, Quebec. The verifications show a high degree of correlation with the
Laboratory’s results.
