MONTAGE GOLD CONTINUES TO RAPIDLY ADVANCE ITS KONÉ

PROJECT WITH FIRST GOLD POUR EXPECTED IN LATE Q4-2026

On-budget with 63% of capital committed • Ball mill shell delivered to site • Continued strong exploration focus

HIGHLIGHTS:

› Rapid progress achieved with over 7.2 million hours worked and more than 3,000 employees and contractors on-site

› Key process plant achievements include the erection of all 14 CIL tanks, completion of the oxide sizer, and delivery of

the ball mill shell to site with all preparatory works completed in time for installation, marking a significant milestone

› Other key workstreams completed include site water storage infrastructure and the resettlement village, whilst other

key workstreams such as the HDPE lining of the TSF and grid connection are well advanced

› Construction remains on-budget with more than $545m of capital committed, representing approximately 63% of the

total upfront capital expenditure, with prices in-line with expectations

› Given the strong advancement, the first gold pour is anticipated in late Q4-2026 through the oxide circuit, whilst the

hard-rock comminution circuit remains well on schedule for completion in Q2-2027

› Exploration remains a strong focus at Koné with another initial 90,000-meter drill programme launched for 2026, in

addition to 9,000 meters of drilling planned for the recently awarded Wendé advanced greenfield property

Abidjan, Côte d'Ivoire — January 19, 2026 — Montage Gold Corp. (“Montage” or the “Company”) (TSX: MAU, OTCQX: MAUTF)

is pleased to announce that rapid construction progress continues to be made at its Koné project, in Côte d’Ivoire, where the

first gold pour through the oxide circuit is anticipated in late Q4-2026.

A total of over 7.2 million construction hours ha ve been worked since the commencement of the project with key milestones

achieved including the erection of all 14 CIL tanks, piperack and grid mesh walkway s, completion of the oxide sizer and the

delivery of the ball mill to site. Given the strong advancement, the first gold pour is anticipated in late Q4-2026 through an oxide

circuit startup, whilst the hard -rock comminution circuit remains well on track for completion in Q2 -2027. A total of

approximately $545 million of capital has been committed to date, representing approximately 63% of the total upfront capital

expenditure, with prices in-line with expectations.

In parallel, the Company continues to be focused on unlocking value through its exploration programme with approximately

115,000 meters drilled in 2025, compared to its initial budget of 90,000 meters, in addition to 56,000 meters of pre-production

drilling conducted at the Koné and Gbongogo Main deposits. Based on the drilling completed last year, the Company expects to

publish updated Mineral Resource Estimate s in Q1-2026 for several satellite targets, in addition to updated resources for the

Koné and Gbongogo Main deposits along with the results of the pre-production drilling programme which confirmed both the

grade and continuity of the mineralized envelopes and identified high -grade zones. Following on from last year’s success, t he

Company recently launched an initial $16 million drill programme for 2026, comprising 90,000 meters of drilling at the Kon é

project and 9,000 meters for the recently awarded Wendé advanced greenfield property.

Martino De Ciccio, Chief Executive Officer of Montage, commented: “We are very pleased with the momentum generated thus

far to advance our strategy of creating a premier multi-asset African gold producer and delivering value for all our stakeholders.

Construction at our flagship Koné project in Côte d’Ivoire continues to progress at a rapid pace with a number of key milestones

achieved including completion of the oxide sizer and delivery of the ball mill shell on site, which positions us to target a first gold

pour through an oxide circuit start -up in late Q4-2026. Moreover, we are continuing to enjoy significant exploration success at

the Koné project given the discovery of higher-grade satellites, with notably the Petit Yao discovery announced late last year.

Looking ahead, we are also pleased to be consolidating a project pipeline through the acquisition of African Gold, where recently

published drill results continue to confirm the prospectivity of the Didievi project in Côte d’Ivoire. We are also excited to commence

drilling this year at our newly awarded Wendé advanced greenfield property i n Côte d’Ivoire with the goal of sourcing the next

project through our ability to stake prospective grounds and explore.

I’d like to take this opportunity to thank our employees, contractors, financiers, local stakeholders, and wider partners for their

strong dedication and support as we continue to deliver on our collective goals.”

Peder Olsen, President and Chief Development Officer of Montage, commented: “Construction activities at our Kon é project

continue to progress at a rapid pace , with more than 7.2 million hours worked to date and number of key milestones achieved

several months early. Notable progress includes the completion of the oxide sizer, erection of 14 CIL tanks and significant progress

on the installation of s tructural steel and piperacks , the commencement of pipework installation , as well as significant progress

on the TSF, with the dam wall completed 3 months ahead of schedule , construction and internal fit out of the 225kV substation

and assembly of transmission line towers.

The delivery of the ball mill shell on site marks a critical milestone on our journey and together with our construction achievements,

positions us to target first gold pour through an oxide circuit start-up in late Q4-2026. Concurrently, we continue to make rapid

progress on the hard-rock comminution circuit which remains on-budget and well on-schedule for completion in Q2-2027.

The resettlement village has been successfully completed and is now fully occupied following the opening ceremony for the village,

which was attended by more than 1,000 people and is a reflection of our strong partnerships with our local stakeholders given

our win-win partnership approach.

In parallel to our construction efforts, we are making good progress on executing our operational readiness plan, with the

mobilisation of high calibre operating teams and mining equipment scheduled to occur over the coming quarters.

Looking ahead, we are excited with the ongoing efforts to build a project pipeline with the goal of leveraging our in -house

construction expertise to unlock further value for our stakeholders.”

EXPLORATION PROGRAMME

In 2025, a total of approximately 115,000 meters were drilled at the Koné project with efforts focused on delineating higher-

grade satellite resources. The programme resulted in the publication of increased resources at Koban North, Gbongogo South

and ANV, with further resource update s expected to be published in the coming months , along with maiden resources other

targets such as Soman 1 & 2 and Petit Yao. In addition, a resource update is also expected to be published for the Koné and

Gbongogo Main deposits along with the results of the 56,000 meters of pre-production drilling which confirmed both the grade

and continuity of the mineralized envelopes and identified high-grade zones.

Following on from last year’s success, the Company recently launched an initial $16 million drill programme for 2026, comprising

90,000 meters of drilling amounting to $14 million for the Koné project and 9,000 meters amounting to $2 million for the recently

awarded Wendé advanced greenfield property, with details by area detailed in Table 2 below.

The 2026 exploration programme is focused on three parallel tracks:

› Infill and extension drilling of previously delineated starter deposits, including the more advanced Gbongogo South, Koban

North and ANV deposits, as well as other previously delineated deposits;

› Advancing pre-resource targets toward maiden resource definition , including the Petit Yao target which has the potential

to be delineated into a high-grade satellite of scale; and
