Bonterra Intersects 2.23 g/t Au over 8.2 m,
Including 9.26 g/t Au over 1.7 m on its 100%
owned Desmaraisville South Project
Val-d'Or, Quebec--(Newsfile Corp. - February 5, 2024) -
Bonterra Resources Inc. (TSXV: BTR)
(OTCQX: BONXF) (FSE: 9BR2) (
"
Bonterra
" or the "
Company
"
)
is pleased to announce the latest
results from its 15,000 meters ("
m
") drill program at its 100% owned Desmaraisville South project. The
purpose of the program was to test 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
")
and to identify the location of two regional corridors of deformation located further to the North of the
project.
The diamond drilling was conducted within seven kilometers ("
km
") of the Bachelor Mill Complex. To
date, Bonterra has received the assay results from 10,631 samples including QA-QC samples from the
57 diamond drill holes completed between August 23 and December 22, 2023. Assay results from
3,708 drill core samples are still pending. Please refer to press releases dated December 4 and
December 14, 2023, for exploration updates on the Desmaraisville South project and the surrounding
area.
Highlights Include:
2.23 g/t Au over 8.2 m, including 9.26 g/t Au over 1.7 m in hole BRDS-23-021
15.30 g/t Au over 1.0 m in hole BRDS-23-030
0.80 g/t Au over 11.7 m, including 2.84 g/t Au over 1.4 m in hole BRDS-23-013
3.66 g/t Au over 1.5 m in hole BRDS-23-004A
Marc-André Pelletier, President and CEO commented: "With the launch of the $10 million in exploration
drilling as part of the Option Agreement with Osisko Mining on the Phoenix JV and positive results from
the 2023 campaign at our 100%-owned Desmaraisville property, this year holds transformative potential
for Bonterra. Notably, all drill hole mineralized intersections at Desmaraisville fall within 4 km of the
Bachelor Mill Complex. The discovery of a new mineralization type on the east side of the O'Brien
Intrusive in hole BRDS 23-021, distinct from the mineralization typically found at the Bachelor-Moroy
deposits, underscores the possibility of new findings on the Desmaraisville property. Compilation work
is ongoing, and the final interpretation of the 2023 geophysical surveys are expected soon. These
findings will contribute to generating highly prospective drill targets for exploration later this year."
Highlights of the Diamond Drilling Results:
The diamond drilling program at the Desmaraisville South project had several objectives. The main
objectives were to intersect gold mineralization; (1) on the eastern side of the O'Brien Intrusive ("
East
Area
"), (2) along the extensions of various gold zones discovered in 2015 south of the O'Brien Intrusive
("
South Area
"), (3) related to geophysical targets on the west of the Bachelor Lake felsic intrusion
("
Bachelor Lake Intrusive
") enhanced by the presence of gold showings at surface and finally, (4) to
test the deep southwest plunge of a zinc, lead, and silver mineralized body of the former Coniagas Mine
(Figures 1 and 2).
In addition, drill holes were positioned to improve the understanding of the stratigraphy on the property
and to better position the boundaries of the various formations within it. The Company is also seeking to
better locate two major structures that affect these formations: the Opawica-Guercheville deformation
corridor, which hosts numerous gold showings and deposits that have been the subject of historical
resource calculations, and the Lamarck-Wedding Fault, host to the former Shortt Lake Gold Mine.
Recent geophysical surveys on the Desmaraisville property should help Bonterra to properly position
these two major structures.

The gold mineralized zone containing 2.23 g/t Au over 8.2 m, including 9.26 g/t Au over 1.7 m in hole
BRDS-23-021 (Figures 2 and 3) is located at the contact between a tuff and a massive basalt rock unit.
The contact zone is moderately silicified and contains 2-3% pyrite in clusters. This type of gold-bearing
environment is different from the Bachelor and Moroy gold-bearing environment. This new mineralized
zone appears to be related to a structural lineament trending N080 to N070 and this lineament is more
than one km in length. Borehole BRDS-23-030 (Figure 2) is more than 275 m deep and has intersected
an atypical gold mineralization characterized by a strong epidote alteration with a low sulphide content.
The best mineralized interval returned a value of 15.30 g/t Au over 1.0m.

Drill hole BRDS-23-013 (Figure 4) intersected a gold enriched zone (0.80 g/t Au over 11.7 m, including
2.84 g/t Au over 1.4 m) associated with a strongly altered felsic dike west of the Bachelor Lake Intrusive.
The host rocks directly in contact with the dike are strongly silicified. It remains to be determined whether
the IP geophysical anomaly is related to this mineralized zone and if so, the mineralized zone could
extend for several hundred metres.

Quality Control and Reporting Protocols
The Desmaraisville project's drill core gold analyses are performed at Activation Laboratories
("
Actlabs
") located in Ste-Germaine-Boulé, Quebec, and at the Agat Laboratory ("
Agat
") located in Val
d'Or, Quebec. The external laboratories employ 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 drilling program a total of 12,179 drill core samples and 2,160 QA-QC samples, have been sent to
Actlabs and Agat.

other judicial, regulatory, political, and competitive developments; technological or operational difficulties
