Abidjan, Côte d’Ivoire — March 18, 2024 — Montage Gold Corp. (“Montage” or the “Company”) (TSXV: MAU, OTCQX: MAUTF)

is pleased to announce the strengthening of its leadership team with the appointment of Silvia Bottero to the position of Executive

Vice President of Exploration, effective July 1, 2024.

Silvia Bottero is an accomplished business-minded geologist, with a proven track record of making high quality brownfield and

greenfield discoveries with the goal of quickly attaining reserve status. Having been based in Abidjan, Côte d’Ivoire, since 2013

through her positions with La Mancha and subsequently with Endeavour Mining, she has developed a deep understanding of the

region’s geological setting and established strong relations with local stakeholders. She most recently held the position of Senior

Vice President of Exploration at Endeavour Mining, overseeing all its African exploration activities. Over the last decade, she has

been credited with the discovery of over 15Moz1 of Measured and Indicated (“M&I”) gold resources in Côte d’Ivoire, with notably

the discovery of over 8Moz1 M&I gold resources at the Ity mine which transformed the asset from a 50kozpa heap-leach operation

to a +300kozpa CIL operation, the discovery of over 3Moz1 of M&I gold resources at Lafigué which led to a construction decision,

and most recently the discovery of approximately 4.5Moz1 M&I gold resources at the Tanda-Iguela greenfield property which has

the potential to be a Tier 1 asset.

Martino De Ciccio, CEO commented, “I’ve had the pleasure of working with Silvia for over a decade and I am thrilled to welcome

her to Montage where her extensive experience in Africa, and most notably in Côte d'Ivoire, will be instrumental to delivering our

strategy of becoming a premier African gold mining company. Silvia’s ability to set an exploration strategy based on effectively

screening and ranking both near-mine and greenfield targets will be invaluable as we embark on our exploration efforts to

delineated more higher-grade deposits in proximity to Koné and to develop a greenfield exploration pipeline to fuel our future

growth.”

Silvia Bottero, incoming Executive Vice President of Exploration, commented: “I am thrilled to join Montage at this exciting stage

in the company’s growth. While the Koné project already ranks as one of the highest quality gold projects in Africa given its sizeable

low-cost production and long mine life, I am very excited with its exploration potential due to the many identified targets on its

extensive tenement holding. I’ve tracked closely the development of the Koné project, as some of its grounds were previously held

by the Endeavour Mining and Barrick joint-venture, and I look forward to working with the team to screen and rank the satellite

targets to prioritize those with higher grade. I am equally excited with the opportunity to build a greenfield development pipeline

in Africa with the goal of sourcing our next project through our exploration success.”

securities legislation (collectively, “Forward-looking Statements”). All statements, other than statements of historical fact,

constitute Forward-looking Statements. Words such as “will”, “intends”, “proposed” and “expects” or similar expressions are

intended to identify Forward-looking Statements. Forward looking Statements in this press release include statements related to

the use of proceeds from the Offering; the final acceptance of the TSX Venture Exchange; the Company’s mineral reserve and

assumptions. There can be no assurance that such statements will prove to be accurate, and actual results and future events could

differ materially from those anticipated in such statements. Important factors that could cause actual results to differ materially

from the Company's expectations include uncertainties inherent in the preparation of mineral reserve and resource estimates and

definitive feasibility studies such as the Mineral Reserve Estimate and the UFS, including but not limited to, assumptions underlying

the production estimates not being realized, incorrect cost assumptions, unexpected variations in quantity of mineralized material,

NON-GAAP MEASURES

This press release includes certain terms or performance measures commonly used in the mining industry that are not defined

under International Financial Reporting Standards (“IFRS”), including cash costs and AISC (or “all-in sustaining costs”) per payable

ounce of gold sold and per tonne processed and mining, processing and operating costs reported on a unit basis. Non-GAAP

measures do not have any standardized meaning prescribed under IFRS and, therefore, they may not be comparable to similar

measures employed by other companies. The Company discloses “cash costs” and “all-in sustaining costs” and other unit costs

because it understands that certain investors use this information to determine the Company’s ability to generate earnings and

cash flows for use in investing and other activities. The Company believes that conventional measures of performance prepared

in accordance with IFRS, do not fully illustrate the ability of mines to generate cash flows. The measures, as determined under

IFRS, are not necessarily indicative of operating profit or cash flows from operating activities. The measures cash costs and all-in

sustaining costs and unit costs are considered to be key indicators of a project’s ability to generate operating earnings and cash

flows. Non-GAAP financial measures should not be considered in isolation as a substitute for measures of performance prepared

in accordance with IFRS and are not necessarily indicative of operating costs, operating profit or cash flows presented under

IFRS. Readers should also refer to our management’s discussion and analysis, available under our corporate profile at

www.sedarplus.ca for a more detailed discussion of how we calculate such measures.
