Montage Gold expands its exploration portfolio in Côte d’Ivoire along its Koné Project and is granted a new greenfield property

HIGHLIGHTS:

• Koné project land package increased by 381km² to 1,699km² following the grant of the Gbatosso permit which is situated along strike of two major mineralized trends on the property and within trucking distance to the Koné processing plant
• Koné is one of West Africa's largest gold projects by land area, which comprises 7 mineralised trends hosting over 50 identified targets with mineralization confirmed at all 23 targets drill-tested so far in 2024 and 2025
• Montage has also been granted the Wendé permit which is an advanced greenfield exploration property strategically located along a well-known major north-south mineralised trend with prior historical exploration activity
• Montage is well positioned to continue to unlock exploration value by advancing exploration at its Koné project, where construction continues to progress on-budget and on-schedule, while progressing its greenfield exploration strategy
  
  

ABIDJAN, Côte d'Ivoire , Dec. 16, 2025 -- Montage Gold Corp. ("Montage" or the "Company") (TSX: MAU, OTCQX: MAUTF) is pleased to announce that the Ministry of Mines, Petroleum and Energy, in conjunction with the Ministry of Finance and Budget and the Ministry of the Environment, Sustainable Development and Ecological Transition, of Côte d'Ivoire, has approved the grant of two exploration permits to Montage which strategically increases its Koné project land package and adds the highly prospective Wendé advanced greenfield exploration property.

The Koné project land package has increased by 381km² to 1,699km² following the grant of the Gbatosso exploration permit (PR0875), which is located in a highly prospective area along the continuity with the Lokolo and Yeré trends, within trucking distance to the Koné processing plant.

In addition, Montage has been granted the Wendé permit (PR1044), covering an area of approximately 107km², located along the Ouango-Fitini shear zone in close proximity to several other significant gold mining operations and deposits. Historical workings on the property highlight a significant 7km² gold-in-soil anomaly with assays grading over 100ppb. Exploration activities on the Wendé property are set to beginning in early 2026 with both geochemical and geophysical surveys, in addition to exploration drilling on prospective targets.

Martino De Ciccio, CEO of Montage, commented: "We are delighted to be granted additional exploration permits in Côte d'Ivoire which both strategically expands our land package along the Koné project and adds the highly prospective Wendé advanced greenfield exploration property. Moreover, it reflects the strong support we continue to receive from our local stakeholders as we strive to position Montage as the partner of choice through our win-win approach and strong focus on local content.

With construction at the Koné project rapidly advancing, remaining on-budget and well on-schedule, we are well positioned to unlock significant exploration value by leveraging our extensive technical expertise and established presence in the region. The recently announced acquisition of African Gold will add the high-quality resource-stage Didievi project, which is expected to provide near-term growth, while the recently granted Wendé property provides the potential to source the next project organically.

We are very pleased with the momentum generated across the business as we continue to execute on our strategy of creating a premier multi-asset African gold producer and delivering value for all our stakeholders."

Silvia Bottero, EVP Exploration of Montage commented: "We are very pleased to have secured the Gbatosso permit given its highly strategic positioning within the Koné project as the Lokolo trend and Yeré trend, which are both known to host significant gold mineralisation as demonstrated with our recent drilling campaigns, are known to extend into the Gbatosso permit. We continue to be very excited with the exploration potential at our Koné project and look forward to continuing to deliver strong resource growth next year, including a maiden resource for the recently announced Petit Yao discovery where drilling is now intensifying.

Additionally, the award of the highly prospective Wendé advanced greenfield exploration permit marks a milestone in Montage's exploration strategy as we embark to create a multi-asset exploration pipeline with the goal of sourcing the next project organically through our ability to stake and explore grounds. Wendé is located on a major gold mineralised and structurally important trend where historical exploration work on the property confirmed its prospectivity. As such, we look forward to commencing our exploration work at Wendé in early 2026."

KONÉ PROJECT LAND EXPANSION
The Koné project land package has increased by 381km² to 1,699km² following the grant of the Gbatosso exploration permit (PR0875), which is located in a highly prospective area along the continuity with the Lokolo and Yeré trends, within trucking distance to the Koné processing plant, as shown in Figure 1 below.

RECENTLY AWARDED WENDÉ GREENFIELD EXPLORATION PERMIT
As shown in Figure 2 below, the Wendé permit, located approximately 500km northeast of Abidjan, is situated along the Ouango-Fitini Shear Zone, a major regional north-south trending structure that stretches as far north as Endeavour Mining's Houndé and Mana mines in Burkina Faso and extending deep into Côte d'Ivoire. The structure and associated splays separate early Birimian granitoids from the Birimian greenstone belt, with a series of contrasting lithologies comprising volcanic and volcano-sedimentary units alongside late felsic plutons, typical of the regions known prospective greenstone belts.

As shown in Figure 3 below, historical workings on the property highlight a significant 7km² gold-in-soil anomaly with assays grading over 100ppb at a target previously known as the Bobosso prospect. The anomaly overlies a strong magnetic high, with perpendicular east-west structures cross-cutting the main NNE-SSW structures, whilst the permit more broadly has also historical soil sampling, geophysical surveying, Rotary Air Blast ("RAB"), Reverse Circulation ("RC") and Diamond Drilling ("DD"). Montage has identified the Wendé permit as highly prospective given the potential of the Bobosso target and widespread soil anomalies that have not been adequately followed up with drilling, suggesting a high potential for trend and target generation.
