Bonterra Intersects Near-Surface
Mineralization Near Its Bachelor Mill Complex
at Its 100% Owned Desmaraisville South
Project
Val-d'Or, Quebec--(Newsfile Corp. - December 17, 2024) -
Bonterra Resources Inc. (TSXV: BTR)
(OTCQX: BONXF) (FSE: 9BR2) (
"
Bonterra
" or the "
Company
"
)
is pleased to announce initial assay
results from its 4,761 meters ("
m
") diamond drilling campaign at its 100% owned Desmaraisville South
Project ("
the
Project
"). The campaign aimed to test several new targets, focusing on: (1) observations
from the 2024 fieldwork campaign, (2) follow-up on promising gold-mineralized environments identified
in the 16,000 m fall 2023 drill campaign, (3) newly identified geophysical IP targets within the Opawica-
Guercheville regional deformation corridor, and (4) the near-surface extension of the Hewfran gold
mineralized zone.
All drill holes are located within 5 kilometers ("
km
") of the Bachelor Mill Complex, ranging from near
surface to a depth of less than 300 m. One drill hole, BRDS-24-072, was drilled on the Nelligan joint
venture ("
Nelligan JV
") in partnership with O3 Mining Inc. (now Agnico Eagle Mines Ltd or "
Agnico
")
where Bonterra holds a 70% interest in the Nelligan JV (see O3 Mining press release dated December
12, 2024, for more details on the acquisition by Agnico). The Nelligan JV covers an area equivalent to
approximately 15% of the Project.
Marc-André Pelletier, President and CEO commented: "This year's exploration efforts have led to the
discovery of four new mineralized zones within 5 km of our 100% owned Bachelor Mill Complex on the
Desmaraisville property. These zones are near surface, exhibit extensive widths of mineralized material
suitable for mining, and will be prioritized for future follow-up work. With significant potential for additional
discoveries, we remain committed to actively exploring the property, leveraging the benefits of innovative
technologies like VRIFY's AI-assisted mineral discovery platform. Furthermore, we are excited to
welcome Agnico Eagle as a partner following the transaction with O3 Mining, and we look forward to
collaborating on the Nelligan JV with our new partner."
The campaign consisted of 16 diamond drill holes completed between August to November 2024.
A
total of 2,500 diamond drill core (NQ) samples, along with 408 Quality Assurance and Quality Control
("
QA/QC
") samples, were submitted to various laboratories. To date, 682 analytical results remain
pending.
Highlights Include:
1.13 g/t Au over 16.0 m, including 2.02 g/t Au over 6.0 m in hole BRDS-24-063
5.30 g/t Au over 1.4 m, including 18.39 g/t Au over 0.4 m in hole BRDS-24-060
2.58 g/t Au over 6.0 m, including 4.50 g/t Au over 3.2 m in hole BRDS-24-065
0.59 g/t Au over 22.3 m, including 3.17 g/t Au over 2.4 m in hole BRDS-24-066
Highlights of the Diamond Drilling Results
The diamond drilling campaign at the Project was performed on four different areas based on results
from the fall 2023 drill campaign, compilation work and a fieldwork campaign conducted during the
spring and summer of 2024 (Figure 1).

At the East Area, new drill holes were positioned to better intersect Northeast trending gold-bearing
geological structures reinterpreted from the 2024 mapping campaign. Drill hole BRDS-24-060
intersected a hydrothermal breccia with 4-6 % fine grained pyrite. Further to the south, two drill holes,
BRDS-24-061 and BRDS-24-066, were drilled at a similar azimuth and intersected highly fractured and
sheared horizons with pyrite mineralization (Figure 2 and Tables 1 and 2).

West of the Bachelor Lake Intrusion, new drill holes were drilled to test the extensions of the gold
intercept in drill hole BRDS-23-013 (0.80 g/t Au over 11.7 m, including 2.84 g/t Au over 1.4 m (see press
release dated February 5, 2024). Drill hole BRDS-24-063 was drilled as an overcut of BRDS-23-013
and intersected a mineralized shear zone with abundant sericite, silicification and pyrite. Drill hole
BRDS-24-065 was drilled as a bracket hole and also intersected a shear zone with abundant sericite,
silicification, carbonate and from 2 to 5% pyrite. It remains to be determined if the gold mineralization is
related to a specific geological structure or late intrusion (see Figure 3, Tables 1 and 2).

New IP targets located in the Opawica-Guercheville regional deformation corridor were evaluated during
this drilling campaign. Three holes, BRDS-24-067, BRDS-24-068 and BRDS-24-072, were drilled at
different locations along the corridor of deformation and intersected moderately to strongly deformed
volcano-sedimentary units crosscut by quartz-carbonate veins with hydrothermal alteration and sulphide
mineralization. Some iron formations and graphitic mudstones horizons were also intersected (Figure 1
and Table 1). Assay results are pending.
The near surface extension of the Hewfran Orebody was also drill-tested. This drilling was designed
following the results of the mapping and sampling program carried out in the summer of 2024. A series
of new channel samples from an old trench returned a graded interval of 2.79 g/t Au over 5.9 m. Four
shallow drill holes were completed to evaluate near-surface projections of new gold mineralized zones,
possibly located up-dip of the Hewfran orebody. Drill hole BRDS-24-057 intersected near surface
strongly silicified and hematized horizon with pyrite mineralization (Figure 2 and Tables 1 and 2).

Quality Control and Reporting Protocols
The Desmaraisville South Project's drill core gold analyses were performed at Activation Laboratories
("
Actlabs
") located in Ste-Germaine-Boulé, Québec, and at the Agat Laboratory ("
Agat
") located in Val-
d'Or, Québec. These 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. Other core samples gold analysis was performed at MSALabs of Val d'Or, Québec. The
samples were crushed to a particle size of 70% passing through a two-millimeter sieve, and then a 500-
gram portion was taken for gold analysis by gamma ray (PhotonAssay
TM
). As per MSALABS' internal
procedure, blank samples, and certified reference materials are systematically inserted into the analysis
sequence. MSALABS operates several laboratories worldwide and holds ISO-17025 accreditation for
numerous metal determination methods, including the photon assay method.
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, Québec. The verifications show a high degree of correlation with the laboratory's results.
