Montage Gold achieves first gold pour at its Koné mine on budget and ahead of schedule

HIGHLIGHTS:

• First gold pour at the Koné mine achieved on budget and ahead of the initial schedule of Q2-2027
• +14.1 million hours worked to date with a strong safety record
• Construction of the Koné mine has created approximately 3,600 jobs with over 95% national employment and will create approximately 1,500 permanent roles during operations
• Full ramp-up of the oxide circuit to commercial production expected to be achieved by year-end
• Hard-rock comminution circuit remains on-budget and on-schedule for completion in Q2-2027
• 130,000 meters of drilling is underway at the Koné mine for 2026, which will total 380,000 meters drilled since the 2024 Updated Feasibility Study was published

ABIDJAN, Côte d’Ivoire, Sept. 27, 2026 (GLOBE NEWSWIRE) — Montage Gold Corp. (“Montage” or the “Company”) (TSX: MAU, OTCQX: MAUTF) is pleased to report that it has achieved first gold pour at the Company’s flagship Koné mine, in Côte d’Ivoire, on-budget and ahead of schedule.

Construction began in December 2024, and the first gold pour was achieved on September 26, 2026, yielding approximately 1,140 ounces of gold. More than 400,000 tonnes of ore have been processed since ore was first introduced into the oxide circuit on September 8, 2026. The addition and early completion of the oxide circuit enabled gold production significantly ahead of the initial schedule. The oxide circuit is expected to reach commercial production in Q4-2026, while construction of the hard-rock comminution circuit remains on budget and on track for completion in Q2-2027.

Martino De Ciccio, CEO of Montage commented: “We are thrilled to have achieved first production at our Koné mine safely, on budget, and ahead of schedule. It marks a significant milestone in the rapid execution of our strategy of creating a premier multi-asset African gold producer.

Koné is now the ninth operating gold mine in Côte d’Ivoire and poised to deliver strong benefits for all stakeholders, with approximately 3,600 direct jobs created to date, over 95% of which are nationals, and many more indirectly created. We’d like to thank our employees for their strong dedication along with everyone who has contributed to reaching this important milestone, including our local stakeholders, financiers, suppliers and contractors.

We look forward to continuing to rapidly grow our business by advancing our development pipeline, with notably the Didievi project in Côte d’Ivoire which is poised to become our next development asset.”

Peder Olsen, President and Chief Development Officer of Montage commented: “We are extremely proud to be delivering the Koné project well ahead of schedule and on budget. Our ability to self-perform construction activities has significantly reduced capital cost requirements and allowed us to optimize the construction timeline. Ramp-up of the oxide circuit is progressing well with ore from the Koné deposit being directly fed into the mill, while we look forward to commencing mining activities at the higher-grade Gbongogo Main satellite deposit in late Q4-2026 and other recently discovered higher grade satellite deposits over the course of 2027.”

Construction of the Koné mine has created approximately 3,600 jobs, of which over 95% were nationals thanks to the training programmes initiated prior to launching construction. Montage’s owner-mining operating model has allowed construction employees to transition within the operating team, thanks to further training programmes and on-site truck-driving simulators. Once ramped up, the operation is expected to create approximately 1,500 permanent roles and many more indirect roles.

Mining activities at the Koné deposit are progressing well with low working capital requirements as the oxide circuit allows for minimal rehandling as the majority of the ore mined from surface is being fed directly into the plant. Mining of the higher grade Gbongogo Main deposit is expected to commence in late 2026, while mining at other recently discovered higher grade satellite deposits is expected to commence over the course of 2027.

The Probable Reserves for the Koné mine, as published along with the 2024 Updated Feasibility Study (“2024 Feasibility Study”), stood at 4.01Moz at a grade of 0.72 g/t Au, comprised of 3.52Moz at 0.67 g/t Au and 0.49Moz at 1.43 g/t Au for the Koné and Gbongogo Main deposits, respectively. Given the exploration success, 12 deposits have now been delineated while mineralization has been intercepted at 25 targets with over 20 targets yet to be drill tested. On June 15, 2026, the Company reported that Measured and Indicated (“M&I”) Resources for higher grade satellite deposits have increased by 1.14Moz to 1.66Moz at 1.51 g/t Au compared to 520koz at 1.48 g/t Au, which was used as a basis for the 2024 Feasibility Study whilst Inferred Resources for satellite deposits have increased from nil to 766koz at 1.34 g/t Au. The overall Koné mine M&I Resources have increased by 1.42Moz to 6.29Moz, with grade improving by 27% to 0.80 g/t Au, and Inferred Resources have increased by 1.62Moz to 2.03Moz, with grade increasing by 36% to 0.68 g/t Au, as compared to the basis used for the 2024 Feasibility Study¹.

An exploration programme consisting of over 130,000 meters of drilling is underway at the Koné mine for 2026, which once complete will total over 380,000 meters of drilling since the publication of the 2024 Feasibility Study, aimed at discovering higher-grade satellite deposits with the objective of boosting production from the onset. As previously announced, the Company expects to publish an updated life of mine plan for the Koné mine along with year-end reserves and resources, to incorporate new data for the Koné, Gbongogo Main and other higher-grade satellite deposits, as well as the initiatives undertaken to further unlock value including the oxide circuit, process plant design enhancements, and the shift to an owner-operated mining model.
