Montage Gold Corp: Montage Gold Achieves Key Construction Milestone at Its Koné Project as Process Plant Concrete Works Commenced

ABIDJAN, Côte d'Ivoire, March 24, 2025 (GLOBE NEWSWIRE) -- Montage Gold Corp. ("Montage" or the "Company") (TSXV: MAU, OTCQX: MAUTF) is pleased to announce that rapid construction progress is being achieved at its Koné project in Côte d'Ivoire, where process plant concrete works, including the ahead-of-schedule pouring of Carbon-in-Leach tank foundations, have commenced, marking an important milestone.

Since the mid-December 2024 groundbreaking ceremony, construction activities at the Koné project have significantly ramped up, with the on-site workforce increasing from approximately 350 to 1,700 employees and contractors. Strong progress has been made to take advantage of the dry season, with process plant earthworks and foundations preparation, water storage facility preparation, camp construction and process plant engineering, all advancing at a rapid pace. The project remains on track to pour gold in Q2-2027 and on budget with approximately 25% of the US$835 million capital spend committed thus far, with prices in line with expectations.

Martino De Ciccio, Chief Executive Officer of Montage, commented: "We are very pleased with the rapid construction progress being made at our Koné project in Côte d'Ivoire which builds on the momentum generated over recent quarters to progress our strategy of creating a premier African gold producer and delivering value for all our stakeholders.

We are equally pleased with our ongoing exploration success and look forward to publishing maiden resources in the coming weeks as we deliver against our previously published target of discovering at least 1 million ounces of Measured and Indicated Resources at a grade which is 50% higher compared to the current Koné deposit grade, to be achieved before the commencement of production¹."

Peder Olsen, President and Chief Development Officer of Montage, commented: "We are extremely pleased with the ramp-up of our construction activities as it positions us to take full advantage of the dry season. We are benefiting from last year's rapid success achieved in securing our mining permit and financing, while commencing training programmes, conducting land compensation, and ordering long-lead items.

Given this planning, we now have more than 100 machines on-site and our construction team has grown from 350 to 1,700 people over the last three months, resulting in 730,000 hours worked without a lost-time injury, reflecting our strong focus on health and safety. We are equally pleased with the advancement of the fabrication of long lead time items and in particular the mill.

I would like to thank our team for their strong efforts and dedication thus far, which places us in a strong position as construction progresses."

KONÉ PROJECT CONSTRUCTION UPDATE
Construction is progressing on-budget and on-schedule for first gold pour in Q2-2027, with key highlights summarized below:

• On-site workforce now comprises approximately 1,200 Montage employees and 500 contractors, both of which comprise over 90% Ivorian nationals. Demonstrating its commitment to local content, Montage partnered with the government-accredited Lycée Technique de Mankono to provide practical vocational training programs tailored to the Koné project. Training encompasses steel fixing, building, electricity, masonry, carpentry, plumbing, firefighting, working at heights, environmental management, and heavy equipment operation.
• Strong continued safety record with no Lost Time Injury ("LTI") with more than 730,000 man-hours worked.
• Treatment plant earthworks are more than 30% complete and progressing well as the concrete pouring for the ring beams of the Carbon-in-Leach tanks commenced 3-weeks ahead of schedule, as shown in Figure 1 below.

• Engineering, design, and procurement is being conducted by Lycopodium Minerals Pty Ltd ("Lycopodium"), along with Montage's in-house construction team, following the award of the engineering, procurement and construction management ("EPCM") contract given their involvement in the project since 2018 and their strong track record in West Africa. Infrastructure detailed design is scheduled to be completed in Q2-2025, and process plant engineering and procurement is 30% complete compared to the 17% target within the baseline schedule. Key civil design areas such as that for the CIL ring beams, the mill raft, and the reagent foundation have been issued for construction. Detailed design of the steel work for the CIL trains, main pipe racks, thickeners and the elution building are nearing completion, while the steel and platework fabrication contracts have been awarded.
• Earthworks equipment has been received, comprising 35 dump trucks, eight 20-tonne vibrating compactors, 10 excavators, 4 bulldozers, 3 graders, 8 concrete trucks, 5 telehandlers, 2 container loaders, and 4 90-tonne rough terrain cranes, as shown in Figure 3 below.

• Access roads and laydown yard is more than 60% complete, with key drainage infrastructure installed.
• Tailings Storage Facility ("TSF") key equipment is on schedule to be delivered in Q3-2025, while the TSF haul road is more than 35% complete.
• Power will be drawn from the national grid operator, Compagnie Ivoirienne d'Electricite ("CIE"), via a new 225kV transmission line connecting to existing power lines located approximately 20km from the processing plant area. The CIE has confirmed capacity to meet the demand requirements for the Koné project and Montage has conducted a power system study with CIE which supports the delivery of high-quality power. A project management agreement has been executed with CIE and works commenced on-site with clearing for the sub-station.
  
• Permanent camp construction is well advanced with 80 rooms now complete, with a further 160 prefabricated rooms under assembly, as shown in Figure 5 below.

• Livelihood Restoration Plan is underway with projects launched focusing on agricultural development and financial literacy programs. A total of 130 individuals from affected villages were also trained in civil construction works at accredited institutions, enhancing employability and aligning with our local employment policy. In addition, over 450 individuals from impacted communities received free literacy training providing empowerment and employment opportunities.
  

Timeline to first gold pour
The Company remains on track for first gold pour in Q2-2027, based on a 27-month construction period for the process plant, with key upcoming milestones presented in Table 1 below. As noted above, major construction works for the water storage dam, site infrastructure, and earth and concrete works are well underway. Approximately 25% of the US$835 million capital has been committed thus far, with prices in line with expectations.

Exploration activities
Montage remains on track to achieving its short-term exploration target, as published on October 7, 2024, of discovering more than 1Moz of Measured and Indicated Resources, at a grade 50% higher than the Koné deposit, to be achieved before the commencement of production. Achieving the set exploration target would represent a significant return on the exploration investment and aligns with the Company's strategic objective of boosting production from the commencement of production while maintaining an annual production of at least 300koz for more than 10 years¹.

The 2024 drilling campaign comprised a total of over 81,000 meters across the Koné project for a total expenditure of approximately US$13 million. Given the success of the drill programme, Montage expects to publish maiden resources in the coming weeks for notably the new discoveries made.

The 2025 drilling campaign is well underway, comprising 90,000 meters of drilling at an approximate cost of US$14 million, focused on both resource delineation of existing deposits and testing new targets.
