Bonterra Expands Multiple Gold Mineralized Zones at Barry; Highlighted
by 7.4 g/t over 14.7 metres, Including 20.6 g/t over 4.9 metres
Val-d’Or, QC – March 31, 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. Recent drilling was de signed to expand the Barry “H-Series”
gold mineralized zones at depth ( S e e F i g u r e s 1 a n d 2 ) . T h e l a test drilling resu lts encompass
11 expansion diamond drill holes (4,794 metres (“ m”)), including six drill holes that were deepened to
test for potential extensions o f “H-Series” subparallel zones. Drilling was highlighted by a wide zone
of mineralization in drill hole MB-21-340 that intercepted 7.4 grams-per-tonne gold (“g/t Au”) over 14.7
m. 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 (the “ 2021 Resource Update”), which is expected to incorporate
approximately 130,000 m of new dr illing information, including results presented today. In addition,
work on the the Preliminary Economic Assessment (“PEA”) is ongoing and is expected to be completed
in the fall of 2021 (See press release dated March 1, 2021).
Highlights:
7.4 g/t Au over 14.7 m and 1.4 g/t Au over 6.8 m in hole MB-21-340
3.8 g/t Au over 6.8 m and 2.1 g/t Au over 6.6 m in hole MB-21-339
3.5 g/t Au over 6.3 m in hole MB-20-255
3.9 g/t Au over 2.7 m in hole MB-20-278
Pascal Hamelin, CEO commented: “The ongoing drilling results at Barry are very encouraging and
support our view that tremendous exploration potential remains within the camp near existing
infrastructure. Several histori cal intercepts suggest the pote ntial for higher-grade material to the west
and drill hole MB-21-340 is no exception. There are currently two diamond drill rigs operating at Barry.
Importantly, having several para llel gold-bearing structures al lows for drilling to pierce several zones
with each hole. The Company continues to test extensions of the deposits at all three of the Company’s
flagship assets in preparation of the upcoming resource update expected in Q2/21.”

The Company has drilled 70 holes and deepened six existing hole s representing a total of 28,658 m at
Barry since July 23, 2020. Results from eight drill holes have been received since the press release dated
March 1, 2021. Results from the remaining three holes are still pending (See Table 1 and Figures 1 and
2).
The Barry gold deposit is characterized as multiple sub-parallel, sub-vertical, shear zones and a second
set of subparallel “H-Series” v eins dipping 50 to 60 degrees to the south hosted within intermediate to
mafic volcanics and tuffs with loc al felsic intrusions. Gold m ineralization consists of disseminated
sulfides within the shear zones and the veins with local visibl e gold. The Barry deposit has been
delineated over 1.4 kilometres 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 w ithin the 2021 Resource Update. Pending assays of samples awaiting
analysis from drilling beyond the project models not included i n 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.
Six existing drill holes (MB -18-189, MB-18-191, MB-18-198, MB-2 0-246, MB-20-255 and MB-20-
278) were deepened and five new holes (MB-21-336 to 340) target ed the expansion of key areas
confirming mineral continuity with in the inferred resource from the 2019 Barry mineral resource
estimate. Drilling results confirm the expansion of multiple “H-Series” subparallel zones open at depth
in the central and west areas of the Barry deposit.
The following holes have returned significant grades in this se ctor; MB-20-255: 3.5 g/t Au over 6.3 m
in the H15 Zone; MB-20-278: 3.9 g/t Au over 2.7 m in the H15 Zo ne; MB-21-339: 3.8 g/t Au over 6.8
m in the H12 zone and 2.1 g/t Au over 6.6 m in the H15 zone; MB -21-340: 7.4 g/t Au over 14.7 m in
the H8 Zone and 1.4 g/t Au over 6.8 m in the H15 Zone. Hole MB -21-336 intersected the 1000 zone
returning 2.0 g/t Au over 2.0 m confirming that mineralization along this Barry zone remains open
towards the east and at depth (See Table 1 and Figures 1 and 2).
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. Pending assays of samples awaiting analys is from drilling beyond the project
models not included in the 2021 Resource Update are to be processed at Actlabs, based in northwestern
Quebec.
