Bonterra intersects 11.3 g/t Au over 2.2 metres from the ongoing
expansion drilling campaign at Barry
Val-d’Or, QC – August 16, 2021 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF,
FSE: 9BR2) ( “Bonterra” or the “ Company”) is pleased to announce the results from the ongoing
drilling campaign at the Barry project. Recent drilling contin ues to expand the H series at depth in the
SW sector and up-dip to the NW (Figure 1). The latest results encompass nine diamond drill holes
designed to expand the 2021 mineral resource estimate (“ MRE”) released in June (see press release
dated June 23, 2021), and one hole (MB-21-353) that was include d in the MRE. Drilling highlights
include 11.3 grams-per-tonne gold (“g/t Au”) over 2.2 metres (“m”) in the H15 zone.
The Company is currently drilling at a rate of approximately 10,000 m per month at its three main gold
deposits to expand upon the recently released MREs. In addition, work on the preliminary economic
assessment (“PEA”), which would utilize the existing Bachelor Mill as a central processing facility is
ongoing and is expected to be completed in Q4 2021.
Highlights include:
11.3 g/t Au over 2.2 m in hole MB-21-361
3.0 g/t Au over 7.0 m, including 6.5 g/t Au over 3.1 m in hole MB-21-353
3.0 g/t Au over 6.8 m, including 6.2 g/t Au over 2.0 m in hole MB-21-372
14.8 g/t over 0.4 m in hole MB-21-352
Pascal Hamelin, CEO commented: “Today’s drill results of the H series reinforce the expansion potential
we see across the entire Barry project. More assay results are expected from Barry in the coming months
as a backlog of pending results are returned from the laboratory and from the ongoing drilling campaign
of expansion targets, which remain open in all directions.”

Figure 2 – Barry H15 Zone Longitudinal Section
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.
The Barry drilling campaign is currently focused on the expansion of key gold mineralized zones around
the MRE. Drilling results presented here targeted the expansio n of “H-Series” and “Contact” zones in
the west sector at depth and up-dip in the footwall of the D2 intrusive. These results confirm the potential
to continue expanding these zones, with success along the H15 a nd D2 HW zones (Table 1; Figures 1
and 2). These zones remain open across the Barry deposit. Two new H series zones were also identified
in the NW sector nearer to surf ace in the FW of the D2 intrusiv e in hole MB-21-352, outlining the
remaining potential within the deposit’s footprint (Table 1; Fi gure 1). Drilling also targeted the NE of
the deposit but assays are still pending (Table 1; Figure 1).

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.
