Bonterra Provides Exploration Update and

Engages Dr. Michel Jebrak to Provide

Technical Advice

Val-d'Or, Quebec--(Newsfile Corp. - May 16, 2024) -

Bonterra Resources Inc. (TSXV: BTR)

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

"

Bonterra

" or the "

Company

"

)

is pleased to provide an update at its

100% owned Desmaraisville project. The Company has now completed the compilation and

interpretation of the results from the 2023 15,000 meters ("

m

") drill program and as well the analysis of

the two geophysical surveys completed in November and December 2023. Several prospective

geological, geophysical and drill targets have been identified and will be subject of field work in the

coming weeks. The purpose of the field work is to prioritize drill targets in preparation for a 9,000 m

diamond drill program scheduled later this year. Please refer to the press releases dated December 4,

2023, December 14, 2023, February 5, 2024, and February 27, 2024, for exploration updates on the

Desmaraisville North and South projects and the surrounding area.

The Company is pleased to announce that it has retained the services of Dr. Michel Jébrak for technical

support on the upcoming drilling campaign. Dr. Jébrak is a well-known professional geologist with a

deep understanding of the Desmaraisville camp geology, gained from prior work in the region. He is an

emeritus professor at University of Quebec's Department of Earth and Atmospheric Sciences. He is a

former Vice-President for Research and Creation at UQAM and holder of the UQAT-UQAM Mining

Entrepreneurship Chair.

Marc-André Pelletier, President and CEO commented: "We are excited to commence field work at our

100% owned Desmaraisville project under the guidance of Dr. Michel Jébrak. Over the next few weeks,

our focus will be on investigating multiple high-grade gold values and new types of mineralization, all

within four kilometers from the Bachelor Mill. Importantly, Dr. Jébrak's expertise promises to offer

insights into the exploration potential of the property.

"At our Phoenix JV, operated by Osisko Mining Inc. ("

Osisko Mining

"), exploration efforts are

progressing well, with approximately 35,000 m drilled to date. Currently, two drill rigs are focused on

regional targets, while five are dedicated to the Moss target, bringing the total of operational rigs on the

Phoenix JV to seven."

Highlights of the Field Work

At the Desmaraisville South and North Properties, the field work is scheduled to commence late May

2024. The field programs will consist to: 1) evaluate several gold showings located within or at vicinity of

the Opawica-Guercheville and the Wedding-Lamarck corridor of deformation where previous exploration

works have returned very high-grade gold intersections in drilling and

channel sample with values of

234.0 g/t over 0.4 m and 582.0 g/t Au over 0.53 m respectively,

2) map and sample outcropping areas with potential near surface gold bearing structures on both

properties, 3) assess low-density circular features (Bouguer anomalies possibly corresponding to late

felsic intrusions like the O'Brien Syenite Intrusion) interpreted from the high-resolution airborne gravity

survey, 4) evaluate OreVision® 2D IP conductors and resistivity anomalies at the Desmaraisville South

Property and 5) map and re-sample old gold bearing trenches to better assess their gold potential

(Figure 1). Any positive results from these programs will help the Company to better focus and prioritize

its diamond drill targets. The proposed 9,000 m drill program will commence later this year.

Caution regarding forward-looking statements

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 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.
