Montage Gold Corp. Announces Government Approval of Mankono Exploration Permits

and Provides Corporate Updates

Vancouver, British Columbia — September 8, 2022 — Montage Gold Corp. (“Montage” or the

“Company”) (TSXV: MAU) (OTCQX: MAUTF) is pleased to announce that on September 6, 2022, the Ivorian

Council of Ministers approved the award of the Gbongogo and Siss éplé Exploration Permits to the

Mankono-Sissédougou Joint Venture (“Mankono”). Public disclosure of these awards can be viewed at

the following url: https://rti.info/politique/13686. This marks a critical step in the process towards closing

of the previously announced acquisition of Mankono by Montage (the “Transaction”, see press release

dated June 8, 2022, for more details). Montage expects to close the Transaction in the coming weeks,

following receipt of the signed Presidential decree in respect of the Gbongogo Exploration Permit. With

the granting of the Mankono permits now approved, Montage is pleased to provide disclosure of the

extensive historic database of results from Mankono for the first time, as well as details of the Company’s

exploration plans and strategy.

HIGHLIGHTS

• Mankono exploration permits approved by Government of CDI

o Transaction to close following receipt of signed Presidential decree; expected in coming

weeks

• 14 drill-ready targets; initial 25,000m of drilling planned

o Drill rig mobilization by end of September

o 65km strike length of soil anomalism

o US$20M in historic exploration with large database

• Transaction will expand Koné Gold Project (“KGP”)

o High-grade reserves delineated following further exploration could significantly improve KGP

o KGP economic study will be revised following aggressive exploration program

• Gbongogo prospect gives high-grade head start 30km from Koné deposit

o Numerous significant intercepts, including:

§ 135.2m at 2.63g/t from 1m

§ 92m at 2.99g/t from 33m

§ 77m at 2.48g/t from 61m

o Initial Inferred Mineral Resource of 5.2Mt at 2.1g/t for 351,000oz at 1.2g/t cut off

§ Open in all directions

• Other top priority targets with high-grade drill results, include:

o Sissédougou: 60m at 2.63g/t

o Bafretou South: 17m at 3.28g/t on strike 6km from Koné deposit

o Dokeka: 13m at 26.80g/t

o Lokolo South: 2m at 32.20g/t

Rick Clark, Montage CEO commented, “We are very pleased to have received notice of the approval of

the Mankono exploration permits and look forward to closing the Transaction with Barrick and Endeavour

upon receipt of the Presidential decree. We very much appreciate the support of the Government of Côte

d’Ivoire towards accomplishing this.

“With the addition of Mankono, our consolidated land position grows to more than 2,250km2 over one of

the most prolific gold belts in West Africa, all of which is within haulage distance of the expanded Koné

Gold Project. We intend to explore aggressively to prove up multiple satellite targets and the high-grade

Gbongogo deposit which remains open in all directions gives us an excellent head start. Based on our

evaluation of the historic data we believe that, in addition to the initial Inferred Mineral Resource at

Gbongogo, the Mankono package has real potential for further discoveries of 0.8Moz to 1.2Moz at a grade

of between 1.5g/t and 2.0g/t*. Given the average mineral reserve grade of the Koné deposit of 0.66g/t,

the addition of higher grade reserves from Mankono could significantly improve the economics of the KGP

going forward.”

*This potential quantity and grade are presently conceptual in nature, and there has been insufficient exploration to

define such a mineral resource and it is uncertain if further exploration will result in the target being delineated as a

mineral resource. The potential quantity and grade were developed based on a review of available historic data, grade,

intersected widths, and possible strike extent at the various prospects and the overall prospectivity of the land package.

DETAILS

Overview of Mankono-Sissédougou Joint Venture Project

Figure 1: Consolidated Land Position

Mankono consists of the Sissédougou Exploration Permit (PR842, 387km2) issued in 2019, the Gbongogo

Exploration Permit (400km2) and the Sisséplé Exploration Permit (106km2) which are all contiguous with

Montage’s Koné Gold Project as shown in Figure 1. Taken together with Montage’s existing land holdings

they form a block of 1,800km2 in exploration permits and a further 458km2 in exploration permit

applications for a total of 2,258km2.

The Gbongogo area has been explored by Randgold (Barrick) since 2013 and the Sissédougou and Sisséplé

areas by Endeavour and previously La Mancha Resources since 2010. The Mankono Joint Venture was

formed in 2017 and exploration has been managed by Barrick since that time.

The database of the historic work includes over 36,000 soil samples, 15,500m of trenching and 31,000m

of air core drilling. Notably only 6,000m of Reverse circulation (“RC”) drilling and 8,560m of diamond core

drilling has been completed most of which is on the Gbongogo prospect. Historic exploration spending on

the combined land package is approximately US$20 million. Figure 2 shows the consolidated land package

with target areas and highlighted results.

Gbongogo Prospect – Immediate High-Grade Impact

The Gbongogo prospect, which lies 30km north of Koné, hosts an initial Inferred Mineral Resource of

5.2Mt grading 2.1g/t for 351koz and is the primary target for resource expansion and upgrade. Montage

expects that this prospect can be expanded quickly and has an initial program of 4,000m planned in

pursuit of this objective.

Mineralization at Gbongogo is hosted within and on the margins of a plunging quartz diorite plug with a

surface expression of only 250m by 100m (see Figure 4). Table 1 shows intercepts from historic drilling

and trenching results. Complete results are presented in Appendix 1 to this release.

Note: True widths vary between 60 and 100% of downhole intercepts with exception of down plunge holes. Intercepts

for holes GBDDH002, GBDDH007 and GBDDH020 include un-assayed gaps, which have been assigned the average

intercept grade.

High grades are controlled by two distinct groups of quartz-tourmaline veins with scope to develop the

grade with well placed drilling. The plunging quartz diorite plug is also yet to be fully defined by drilling.

Furthermore, given the small surface expression there is the potential for other similar intrusive bodies

to be present within the north-south trend that hosts Gbongogo that could have been missed on widely

spaced first pass exploration and it will be a priority to follow up in this area.

Initial Inferred Mineral Resource Estimate

Montage commissioned a Mineral Resource Estimate (“MRE”) by MPR Geological Consultants of Perth,

Australia (“MPR”) based on the historic drill database. MPR estimated recoverable mineral resources

using Multiple Indicator Kriging (“MIK”) based on a dataset that includes 6,142.4m drilling (4,827.4m of

diamond core and 1,315m of RC).

The Inferred MRE is reported within an optimized pit shell based on a US$1,500/oz gold price and is shown

below at a range of cut-off grades. A cut-off grade of 1.2g/t is the base case scenario.

1.20 5.2 2.1 351

Notes

1. Inferred Mineral Resources are reported in accordance with NI 43-101 with an effective date of the 22nd of April

2022, for the Gbongogo deposit within the Koné Gold Project. The Inferred MRE was prepared by Mr. Jonathan

Abbott of MPR Geological Consultants of Perth, Australia who is a Qualified Person as defined by NI 43-101.

2. The inferred MRE is reported on a 100% basis and is constrained within an optimal pit shell generated at a gold

price of US$1,500/ounce.

3. The Mineral Resources are classified according to the “CIM” definition of Inferred Mineral Resources.

4. The estimates at 1.2g/t cut-off grade represent the base case or preferred scenario.

5. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

6. Also see “Mineral Resource Modeling and Estimation Assumptions – Gbongogo”.

Additional Target Areas

Soil sampling across the Mankono project area has defined more than 65km of soil anomalism (see Figure

2). Follow up exploration in the form of pitting, trenching and aircore drilling was widely spaced due to

the nature of the desired target size but has identified a total of twelve targets, in addition to Gbongogo,

where drilling has intersected mineralization with width and grade (see Table 3). These represent

immediate drill targets where Montage will move quickly to drilling.
