THROUGH A STRATEGIC PARTNERSHIP WITH AURUM RESOURCES

HIGHLIGHTS:

› Montage to obtain a 9.9% ownership stake in Aurum through the issuance of 2.89 million common shares of Montage

for deemed aggregate consideration of approximately C$10.4 million

› Montage will be investing alongside Zhaojin and the Lundin Family who will also each obtain a 9.9% interest in Aurum

› Aurum owns the Boundiali and Napié gold projects in Côte d’Ivoire

─ The Boundiali gold project is located immediately north of Montage’s Koné project, where a 100,000-meter drill

programme is currently underway; Aurum expects to publish an updated resource estimate and PFS by year-end

─ The Napié gold project was obtained through the recent acquisition of Mako Gold, for which Aurum has planned a

30,000-meters drill programme for 2025 with the goal of delineating further resources

Vancouver, Canada — May 6, 2025 — Montage Gold Corp. (“Montage” or the “Company”) (TSX: MAU, OTCQX: MAUTF) is

pleased to announce that it has strengthened its position along the Boundiali greenstone belt in Côte d’Ivoire , which hosts

Montage’s Koné gold project, by entering into a strategic partnership with Aurum Resources Limited (“Aurum”)(ASX:AUE), given

its highly attractive exploration portfolio adjacent to that of Montage.

Montage will obtain a 9.9% interest in Aurum through the issuance of 2.89 million common shares of Mont age representing a

deemed consideration of approximately C$10.4 million. Montage will be investing alongside other strategic investors by

participating in a non -brokered private placement (the “Offering”) , including Zhaojin Mining Industry Company Limited

(“Zhaojin”) who will increase their interest in Aurum to 9.9%, and the Lun din Family and their associates (“Lundin Family”) who

will also obtain a 9.9% interest in Aurum. Through the Offering, Aurum will obtain aggregate gross proceeds of approximately

A$35.6 million based on a share issuance price of A$0.356. Montage management and certain insiders will also participate in the

Offering. Aurum had a market capitalization of approximately A$82.7 million (US$53.3 million) prior to the Offering.

Aurum owns the Boundiali and Napié gold projects in Côte d’Ivoire. The Boundiali gold project is located immediately north of

Montage’s Koné project and already hosts an Inferred Resource of 50.0Mt at 1.0 g/t Au containing 1.59 million ounces of gold

as published by Aurum1. A 100,000-meter drill programme is currently underway at the Boundiali gold project, with a particular

focus on the higher grade Nyangboue gold deposit, which is the target located closest to Montage’s exploration grounds. Aurum

expects to publish an updated resource estimate and a Preliminary Feasibility Study (“PFS”) by year-end.

Martino De Ciccio, CEO of Montage, commented: “We are pleased to enter into a strategic partnership with Aurum, further

strengthening our presence along the Boundiali greenstone belt in Côte d’Ivoire, which is emerging as one of West Africa’s most

prospective areas. With our Koné project located immediately south of Aurum’s Boundiali gold project, both companies see

significant opportunity for collaboration to enhance value creation for all our stakeholders. As construction at Koné continues to

rapidly advance on budget with first gold pour well on track for Q2-2027, we remain focused on executing our strategy of creating

a leading African gold producer. This ambition is underpinned by strong partnerships with our host country, local communities,

financiers, strategic shareholders—and now, neighbouring companies such as Aurum.”

1 The estimate was prepared by Aurum and not Montage. Aurum prepared and reported the estimate in accordance with the recommendations of the 2012 Australasian Code for

Reporting of Mineral Resources and Ore Reserves (JORC 2012). See the press release titled “Aurum delivers 1.59Moz Maiden JORC Resource at Boundiali Gold Project” released to the

Australian Securities Exchange on 30 December 2024 and amended on 31 December 2024 and available to view on www.asx.com.au.

Caigen Wang, Managing Director of Aurum, commented: “We are delighted to obtain the endorsement of Montage, along with

the strategic investments from the Lundin Family and Zhaojin, as it is a true endorsement of the quality of our two gold projects

in Côte d’Ivoire. Moreover, we look forward to collaborating with Montage to drive mutual value creation given our proximity

to the Koné project and the track record of both management teams. On completion of this placement, we will have liquidity

sources in excess of A$45 million which will enable Aurum to accelerate growth of gold resources at both Boundiali and Napié.

These funds will be sufficient to complete the Boundiali pre-feasibility study, ESIA study and approval, mining exploitation licence

application and approval as well as the definitive feasibility study, all prior to H2-2026.”

Key terms of the investment

Montage has entered into binding documentation with respect to a transaction (the “Share Exchange Transaction”) with the

following key terms:

› Equity Swap: Montage will obtain a 9.9% ownership in Aurum, through the Share Exchange Transaction, which will result in

the issuance of 32,887,521 Aurum ordinary shares to Montage, and the issuance of up to 2, 887,496 common shares of

Montage (“Montage Shares”) to Aurum equating to an 0. 8% ownership in Montage, for a total implied transaction

consideration of C$10.4 million. The Share Exchange Transaction is based on a Montage share price of C$3.61 and an Aurum

share price of A$0.356, each representing the 5-day VWAP as at May 2, 2025. Montage Shares will be issued to Aurum under

an exemption from the prospectus requirements of applicable Canadian securities laws and will be subject to a hold period

of four months and one day. Any A urum sale of Montage shares will be subject to certain notice rights to enable Montage

Gold to designate a suitable purchaser(s).

› Timing and Approvals: The Share Exchange Transaction and the Offering are subject to the approval of Aurum shareholders

at an Extraordinary General Meeting scheduled for mid-June 2025, and the issuance of the Montage Shares is subject to the

approval of the TSX, and is otherwise expected to close in late June 2025.

Aurum will use the proceeds of the Offering to accelerate resource definition drilling at the Boundiali gold project and exploration

drilling at its Napié gold project, in Côte d’Ivoire, including the purchase of an additional two diamond drill rigs . The proceeds

will also be used to progress technical studies and permit applications.

ABOUT AURUM RESOURCES

Aurum owns the Boundiali and Napié gold projects in Côte d’Ivoire, as summarized below.

Boundiali Gold Project

As shown in Figure 1 below, Aurum owns the Boundiali gold project in northern Côte d’Ivoire, a 1,037km2 exploration property

located along the same greenstone belt as Montage ’s Koné project. The Boundiali gold project demonstrates many geological

similarities to the Koné project and covers a largely underexplored southern extension of the belt where a highly deformed

synclinal greenstone horizon traverses finer grained basin sediments , with sporadic emplacements of granitic bodies along the

margins of the belt.

In December 2024, Aurum announced a JORC-compliant mineral resource estimate (the “Boundiali MRE”) of 1.59Moz at 1.0g/t

Au derived from the BST (Nyangboue), BD Target 1 and 2, and BM Target 1 and 3 deposits.

A 100,000-meter drill programme is currently underway at the Boundiali gold project, with a particular focus on the higher grade

Nyangboue gold deposit, which is the target located closest to Montage’s exploration grounds. Aurum expects to publish an

updated resource estimate and a Preliminary Feasibility Study (“PFS”) by year -end.

Napié Gold Project

Aurum owns the Napié gold project in north central Côte d’Ivoire. The Napié gold project is located 30km southeast of the city

of Korhogo and covers a strike length of 30km . The Napié gold project straddles a land package of 224km 2 and is considered

prospective for gold.

In June 2022, t he Napié gold project had a JORC-2012-compliant mineral resource estimate of 868koz at 1.20g/t Au, based on

the Tchaga and Gogbala deposits, two of four prospects located on the 30km-long Napié Shear. Only 13% of the Napié Shear has

been tested to date.

Aurum is planning 30,000 meters of drilling at Napié in 2025 to expand the current mineral resource estimate.
