Bonterra Commences 2024 Drilling Campaign

at its 100% Owned Desmaraisville South

Project

Val-d'Or, Quebec--(Newsfile Corp. - August 27, 2024) -

Bonterra Resources Inc. (TSXV: BTR)

(OTCQX: BONXF) (FSE: 9BR2) (

"

Bonterra

" or the "

Company

"

)

announces the start of a diamond

drilling program at its 100% owned Desmaraisville South project. Several prospective geological,

geophysical and drill targets have been identified throughout the year and have been prioritized following

last summer's field work carried out by Bonterra's geology team (see Figure 1 for the location of the drill

targets). A drill rig has been mobilized to site and the Company plans to drill from 4,000 to 6,000 meters

("

m

") before the end of the year. Please refer to the press releases dated May 16, 2024, February 27,

2024, February 5, 2024, December 14, 2023, and December 4, 2023, for exploration updates on the

Desmaraisville North and South projects and the surrounding area.

Marc-André Pelletier, President and CEO commented: "The commencement of exploration at our 100%

owned Desmaraisville South project follows the diligent efforts of our geologists to design an optimal

drilling program targeting several promising areas. Our primary goal for this campaign is to discover

new mineralized lenses within 15 kilometers of the Bachelor Mill Complex. Concurrently, the Company is

considering an update to the 2021 mineral resource estimate (the "

2021 MRE

") for the Barry and

Gladiator deposits (see press release dated June 23, 2021). Since the 2021 MRE, Bonterra has

completed over 100,000 m of diamond drilling in and around the Barry and Gladiator deposits. This

exploration comes amid a favorable increase in the price of gold, which was assumed at US$1,600 per

ounce in the 2021 MRE.

At our Phoenix JV, the compilation work continues following the 60,000 m drill campaign that was

completed in July. Drilling activities are expected to continue later this year with Gold Fields as the

operator of the Phoenix JV."

This press release contains "forward-looking information" that is based on Bonterra's current

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

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

announced on November 28, 2023, and the acquisition of Osisko Mining by Gold Fields announced on

August 12, 2024. 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 spacing 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.
