Bonterra Highlights Initial Drill Results from

Gladiator SW Target; Announces 2025

Exploration Program at Phoenix JV with Gold

Fields

Val-d'Or, Quebec--(Newsfile Corp. - March 19, 2025) -

Bonterra Resources Inc. (TSXV: BTR)

(OTCQX: BONXF) (FSE: 9BR2)

("

Bonterra

" or the "

Company

") is pleased to report the first assay

results from the Gladiator Southwest ("

Gladiator SW

") target and announce details of the 2025

exploration program being led by a 100% indirect subsidiary of Gold Fields Ltd ("

Gold Fields

" or the

"

Operator

") at the Phoenix JV (the "

Project

"). The Project is under a definitive earn-in and joint venture

agreement (the "

JV Agreement

") with Gold Fields (previously, Osisko Mining Inc.). Under the JV

Agreement, Gold Fields has the right to acquire a 70% interest in the Project by spending C$30 million

in work expenditures, with a minimum spending commitment of C$10 million per year over a three-year

period (see press release dated November 28, 2023, for more details).

Marc-André Pelletier, President and CEO commented: "Gold Fields has achieved significant progress

in exploration near their high-grade Windfall project, identifying multiple promising targets for further

drilling. With over half of the planned joint venture expenditures already completed in the first year, we

look forward to continued collaboration to advance Quebec's newest emerging gold camp."

First Assay Results from the Gladiator SW Target

To date, over 65,000 meters ("

m

") have been drilled, with approximately C$18 million invested in the

Project under the JV Agreement. This includes 5,700 m (13 drill holes) completed at the Gladiator SW

Target along the Barry Shear Zone by the end of 2024 (see Figure 1 – Plan View of Gladiator SW

Target). Additionally, a detailed review of core samples from both the Barry and Gladiator deposits was

conducted to improve geological understanding. These deposits contain a combined 1.08 million

ounces of Measured and Indicated Mineral resources and 1.68 million ounces of Inferred Mineral

resources, as reported in the 2021 mineral resource estimate ("

2021 MRE

").

2025 Phoenix JV Exploration Program Updates by Gold Fields

Gold Fields is currently preparing a potential 15,000 m drill program, with final target selection subject to

internal review and prioritization. Several promising targets have already been identified, based on

historical gold showings, previous drill results, and geophysical survey data (see Figure 2 – Plan View of

Target Areas on the Phoenix JV).

Gold Fields intends to deploy three to four drill rigs, primarily focused along the Barry Shear Zone at the

Gladiator NE and Titan targets. The program will also explore additional areas such as Duke NE,

Chanceux, the Tourmaline Ridge extension, and Rouleau Till. Diamond drilling is expected to commence

later this year upon approval. Additionally, a gravity airborne survey and associated fieldwork are being

planned for the upcoming summer.

Quality Control and Reporting Protocols (adopted by Gold Fields)

NQ core assays were obtained by either 1-kilogram screen fire assay or standard 50-gram fire-

assaying-AA finish or gravimetric finish at ALS Laboratories in Val-d'Or, Québec, or Vancouver, British

Colombia. The 1-kilogram screen assay method is selected by the geologist when samples contain

coarse gold or present a higher percentage of pyrite than surrounding intervals. All samples are also

analyzed for multi-elements, including silver, using Four Acid Digestion-ICP-MS method at ALS

Laboratories. Drill program design, Quality Assurance/Quality Control ("

QA/QC

") and interpretation of

results is performed by qualified persons employing a QA/QC program consistent with NI 43-101 and

industry best practices. Standards and blanks are included with every 20 samples for QA/QC purposes

by Gold Fields as well as the lab.

Qualified Person

M. Donald Trudel, P.Geo. (OGQ # 813), Director Geology for the Company, has reviewed and approved

the technical information contained in this press release. Mr. Trudel is a qualified person as defined by

National Instrument 43-101 on standards of disclosure for mineral projects.
