Bonterra Announces Start of Exploration

Drilling as Part of the Option Agreement with

Osisko Mining

Val-d'Or, Quebec--(Newsfile Corp. - January 18, 2024) -

Bonterra Resources Inc. (TSXV: BTR)

(OTCQX: BONXF) (FSE: 9BR2)

("

Bonterra

" or the "

Company

") is pleased to announce that

exploration drilling has started on the newly named Phoenix JV (formerly known as the Urban-Barry

Property) (the "

Project

") as part of the definitive earn-in and joint venture agreement (the "

Agreement

")

with Osisko Mining Inc. ("

Osisko

" or the "

Operator

"). Under the Agreement, Osisko has the right to

acquire up to a 70% interest in the Project by spending $30 million in work expenditures, with a minimum

spending commitment of $10 million per year over a three-year period (see press release dated

November 28, 2023).

Osisko plans to drill over 35,000 meters ("

m

") on the Project in 2024, which Osisko expects will meet its

minimum spending commitment of $10 million per year under the Agreement. The Operator has

identified multiple targets on the Project, including the Moss target, which is located only five kilometres

south-west from the Windfall Gold deposit and shows a similar geological character to the Lynx Zone.

The Moss target will be tested along the Mazères Fault that runs across both the Lynx Zone and the

Moss target.

Osisko plans to mobilize up to five drill rigs during the year, primarily along the Mazères Fault on the east

and west sides of the Gladiator and Barry deposits and the Moss target (see Figure 1).

Marc-André Pelletier, Chief Executive Officer, and President of the Company commented "The start of

exploration drilling by Osisko represents an important milestone in the development of the Project. With

a $10 million exploration budget in 2024 and leveraging Osisko's expertise in this exciting new gold

camp, we believe we are well positioned for significant exploration success. In addition, the Company

intends to continue exploring its 100%-owned Desmaraisville Property near the Bachelor Mill Complex in

2024. Compilation work from the 15,000 m drill program carried out in 2023 is ongoing and drilling

results are expected to be released throughout Q1 2024. Last year's exploration drilling combined with

two geophysical surveys, also conducted in 2023, are expected to generate additional and promising

drill targets to be tested later this year."

expectations, estimates, forecasts, and projections. This forward-looking information includes, among

other things, statements with respect to the earn-in and joint venture agreement with Osisko Mining

announced on November 28, 2023. The words "will," "anticipated," "plans" or other similar words and

phrases are intended to identify forward-looking information. This forward-looking information includes

namely information with respect to the planned exploration programs and the potential growth in mineral

resources. Exploration results that include drill results on wide spacings may not be indicative of the

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

information is subject to known and unknown risks, uncertainties and other factors that may cause

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

and other factors should be considered carefully, and readers should not place undue reliance on such

forward-looking information.
