Val-d'Or, Quebec--(Newsfile Corp. - December 4, 2023) -
Bonterra Resources Inc. (TSXV: BTR)
(OTCQX: BONXF) (FSE: 9BR2)
("
Bonterra
" or the "
Company
") is pleased to announce the first drill
results of its 15,000 meters ("
m
") drill program at its Desmaraisville South project. Three diamond drill
rigs have been mobilized on the project and are currently drill-testing several new geological and
geophysical targets along with historical near surface gold mineralization along the edges of the O'Brien
Syenite Intrusion ("
O'Brien Intrusive
").
Located within three kilometers ("
km
") of the Bachelor Mill Complex, three different areas were drill
tested for their near surface gold potential. These areas are located North, East, and South of the
O'Brien Intrusive (Figure 1).
At the Southern Area ("
South Area
"), several new drill targets were generated from the reinterpretation
of previously intersected gold bearing structures. This reinterpretation was done with the use of the
Bonterra drill hole database and the historical 3D models of high-grade gold intercepts drilled previously.
Bonterra has drilled to date a total of 17 diamond drill holes (4,332 m) at the South Area (Figure 2 and
Table 1).
Highlights include:
10.97 g/t Au over 10.1 m, including 16.36 g/t Au over 4.7 m in hole BRDS-23-018
4.79 g/t Au over 6.3 m, including 9.03 g/t Au over 1.5 m in hole BRDS-23-016
2.65 g/t Au over 4.2 m in hole BRDS-23-016
Marc-André Pelletier, President and CEO, commented: "After entering into an earn-in and joint venture
agreement with Osisko Mining Inc. in the Urban-Barry camp, our Company has redirected its exploration
efforts to focus on our 100%-owned Desmaraisville projects, which is close to where the Bachelor Mill
Complex is situated. The current 15,000 m drill program aims to explore new targets across our land
package and validate our improved geological interpretation. The recent discovery of mineralized zones
at Desmaraisville South supports our current understanding of the gold potential, indicating similarities to
the Bachelor and Moroy deposits on the western side of the O'Brien Intrusive, located about 3 km from
the Bachelor Mill. The ongoing drill program with three rigs, set to conclude this year, should provide
valuable insights that will guide our future exploration strategy. It is to be noted that the nearby Bachelor
Mine historically produced over 350,000 ounces of gold from two million tonnes at a grade of 5.0 g/t Au."
The drilling encountered several sub-parallel hematite and silica rich altered zones with trace to 8% fine
grained and disseminated pyrite which host the gold mineralization (Table 2 and Figure 2). From hole to
hole, these mineralized zones show various orientations and suggest that the gold mineralization is
related to a large complex with brittle zones of various orientations and plunges. Many assays are still
pending from the 3,955 submitted samples.
Bonterra's review of the historical database demonstrated a lack of systematic sampling. Several gold
mineralized intervals were not sampled above and below the mineralization. Bonterra will conduct a re-
sampling program in early 2024. When all analytical data is received, Bonterra will update its 3D model
including the geology, alteration, structures, and mineralization to better understand and evaluate the
near surface gold potential of the South Area.

Quality Control and Reporting Protocols
The Desmaraisville project's drill core gold analyses are performed at Activation Laboratories (Actlabs)
located in Ste-Germaine-Boulé and Val d'Or, Quebec and at the Agat Laboratory in Val d'Or. The
external laboratory 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 and with gravimetric finish for
assay above 10 g/t Au at both Actlabs and Agat. Blanks, duplicates, and certified reference standards
are inserted into the sample stream to monitor the Laboratory's performance. The Company's QA-QC
program requires that at least 5 to 10% of the 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. For the South Area, a total
of 3,955 drill core samples and 702 QA-QC samples, have been sent to Activation Laboratories Ltd and
Agat Laboratory.

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 classed 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

Bonterra's actual results, level of activity, performance, 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 markets, environmental and
other judicial, regulatory, political, and competitive developments; technological or operational difficulties
or inability to obtain permits encountered in connection with exploration activities; and labour relations
matters. This list is not exhaustive of the factors that may affect our forward-looking information. These
