PROJECT CONSTRUCTION UPDATE

EPCM award
The Company has awarded the engineering, procurement and construction management (“EPCM”) contract to Lycopodium Minerals Pty Ltd (“Lycopodium”). Lycopodium’s involvement in the project commenced in 2018 and were the engineers for Montage’s Definitive Feasibility Study (“DFS”) and Updated Feasibility Study (“UFS”). In addition, Lycopodium has a strong track record in West Africa and in particular in Côte d’Ivoire, having recently completed construction of Fortuna Mining Corp’s Séguéla project in 2023 and Endeavour Mining Plc’s Lafigue mine in 2024, both on time and on budget. Other projects in Côte d’Ivoire completed by Lycopodium include the Yaouré project for Perseus Mining Ltd, and Endeavour Mining Plc’s Ity CIL and Agbaou projects. Integrating fully into the owner’s team, Lycopodium is responsible for providing Montage with support on the engineering, design, procurement, construction management and commissioning of the processing plant and process related infrastructure.

Order of long-lead items
A significant number of long lead item orders have been committed to by Montage, securing pricing for equipment and services on initial capital of over US$150 million, with key orders placed including:

• Ball mill, high-pressure grinding rolls (“HPGR”) and crushers (primary and secondary)

• Thickeners and CIL tanks

• Key earthworks mobile equipment leases

• Early camp facilities are complete while construction of the permanent camp is underway which will also accommodate construction personnel

Early works
Early works were launched in Q4-2024 and are progressing well with the following key highlights:

• No lost time incidents (“LTIs”), with over 138,890 workhours completed since the commencement of early works

• In line with its commitment to local content, Montage has partnered with the government-accredited Lycée Technique de Mankono to deliver practical vocational training programs tailored to the needs of the Koné project for an initial 80 individuals. The first group of participants, drawn from impacted local communities, has successfully completed its training and is now commencing employment with Montage. This first group includes steel fixers, building electricians, masons, carpenters and plumbers. The second group of trainees began its practical training on October 21, 2024

• In addition, Montage is pleased to be using local contractors for buildings, earthworks and camp electricals

• Montage has initiated a literacy and numeracy program for individuals in nearby affected villages. Currently over 500 participants are attending the programme which aims to empower local communities with essential skills to pursue employment and improve access to economic opportunities and enhance long-term socio-economic resilience

• Land compensation and resettlement activities have begun with access secured to all major early works areas including the plant, camp, water storage facility and the tailings storage facility (“TSF”)

• The resettlement site for the relocation of the Village of Dolourougokaha has been agreed between affected and host communities with housing construction set to commence in late Q1-2025

• With Koné located in a low water stress area, project water will be sourced from the nearby Marahoué river into a water storage facility (“WSF”) and from pit dewatering with a supplementary borefield. The Ministry of Water and Forests granted the required water abstraction authorizations in Q3-2024 and compensation for access clearing for the pipeline is commencing

• Earthworks are underway for the access road construction, clearing of major work areas, and stockpiling of topsoil is ongoing

• Permanent camp construction has begun with the construction of the first 40-man blocks well advanced

• Montage is also focusing on developing an Ivorian supply chain utilising local supply for project and camp consumables, and is advancing major contracts to procure fuel, cement, aggregates and explosive supplies, as well as sustainable food sources

• 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. Natural gas and hydro-electric generation account for approximately 70% and 20% of Côte d’Ivoire’s electricity generation¹ with expansions projects underway to install an additional 1,448MW of natural gas and 297MW of hydro-electric generation capacity. 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, without additional support measures.

Engineering optimizations
Further to Montage’s Updated Feasibility Study (“UFS”) published on January 16, 2024, Lycopodium and Montage have undertaken a comprehensive Front-End Engineering and Design process which has resulted in the optimization of several key design parameters to enhance the crushing and milling circuit and improve the efficiency of the overall operation.

The plant nominal throughput as per the UFS is 11.0 Mtpa, based on a primary crushing, secondary crushing and HPGR, milling and carbon-in-leach (“CIL”) availability of 75%, 88% and 91% respectively. The following engineering improvements have subsequently been made:

• The primary crusher has been upgraded with 33% extra power capacity (from 450kW to 600kW) and the eccentric speed has been increased, which generates the potential to increase the throughput.

• The secondary crushers have been upsized by 50% from (from 600kW to 930kW) to ensure that the secondary crushing circuit, which typically has an availability of 75%, can match the full availability of the HPGR.

• The two HPGR's have been replaced with a single larger unit for ease of maintenance, as well as the ability to accept a coarser feed size.

• The HPGR circuit includes a stockpile in lieu of a surge bin which is expected to provide significantly greater operating flexibility.

• Ball mill installed power has increased by 10% with a single ball mill of 22MW which compared to the two 10MW ball mills previously considered. This single larger mill will be simpler to operate given that the addition of low-speed synchronous motors has eliminated the need for gearboxes in the drive train, reducing components that need auxiliary cooling systems, maintenance and spares.

• The twin seven tank CIL trains provide a combined slurry residence time of 36 hours for the 10% oxide / 90% fresh ore blend. Should Montage decide to further increase the mill throughput, provisions have been made to add an extra tank to each train to either improve residence time or maintain it with the potential to increase throughput.

• Montage continues to engineer the potential addition of an oxide circuit consisting of a sizer and conveyor to directly feed the mill with oxide and transitional material, bypassing the hard rock comminution and HPGR. The current design limits oxide material to 10% of total feed, and requires 18.8Mt of pre-stripping, stockpiling, and gradual reintroduction of oxide material into the feed over the first eight years of production. An oxide circuit would enable an earlier first gold pour while the hard rock comminution is being commissioned, reduce rehandling costs for oxide ore mined in pre-production, provide significant operational flexibility to continue production during maintenance of the crushing circuit and would improve blending optionality. While oxide feed is limited within the Koné deposit, Montage’s ability to discovery more oxide material across new and existing targets will be a determining factor in forming an investment decision for the oxide circuit.
  

Based on these optimization modifications, the treatment plant design now incorporates crushing, screening, HPGR, grinding and classification, pre-leach and tailings thickening, CIL circuit, carbon recovery and acid wash, carbon elution, electrowinning trains and smelting, as further detailed below:

• Primary crushing using a gyratory crusher Metso 54/75 and 600kW drive

• Coarse ore stockpile with 24 hours live capacity (34,200 tonnes) complete with three 50% capacity reclaim apron feeders

• Closed-circuit secondary crushing and screening with nominally duty stand-by cone crushers, Metso MP1250 and 930kW drives, and double deck multi-slope screens, Schenck 4397, to produce a crushed product size P80 of approximately 32mm

• HPGR, Metso HRC2400e with dual 3.0MW drives to produce a nominal P80 of 6mm

• Covered HPGR product stockpile with a live capacity of 4 hours (4,800 tonnes) complete with two reclaim belt feeders

• HPGR product wet sizing/re-pulping screens, Schenck 4397, with undersize slurry reporting to the milling circuit via the cyclone feed hopper

• HPGR screen oversize stockpile complete with three 50% capacity vibrating reclaim feeders

• Primary ball mill, Metso Φ8.53 metre diameter 14 metre long 22MW dual pinion, in closed circuit with 2 clusters of 14 each 500mm diameter hydrocyclones to produce a grind size with a P80 of 75µm

• Pre-leach thickening (44 metre diameter high rate) to increase the slurry density feeding the carbon in leach, CIL, circuit to minimise tankage and reduce overall reagent consumption

• Leach circuit incorporating 14 leach tanks, arranged in two parallel trains of seven each in series, to provide 36 hours leach residence time, and equipped with external oxygen contactors, while provisions have been made to add an extra tank in the future if required

• Twin 17 tonne split AARL elution circuits, electrowinning and gold smelting to recover gold from the loaded carbon to produce a gold/silver doré

• Tailings thickening (44 metre diameter high rate) to recover cyanide and recycle process water from the CIL tailings

• Tailings pumping to the TSF complete with a supernatant reclaim and return system

• River water abstraction system from the Marahoué river and 32km pipeline

Based on the above-described optimization modifications, the total process plant capital cost has increased by US$33 million, or approximately 10%. Based upon a comprehensive review of total project costs accounting for scope changes, realized tender prices, more conservative working capital assumptions (to account for greater volumes of spares and reagents), inclusion of a livelihood restoration programme, and a higher contingency. Consequently, the total capital cost estimate has increased by approximately 12%, from US$742 million to US$835 million, compared to the UFS, as shown in Table 1 below. The UFS assumed US$30 million of vendor financing, mainly related to the mining contractor mobilization, which reduced the upfront capital to US$712 million, whereas given the strong liquidity sources secured by Montage, vendor financing is currently no longer being contemplated for contract mining.

Exploration Update
Montage remains on track to achieve its previously published target of discovering more than 1 million ounces of Measured and Indicated resources, at a grade 50% higher than the Koné deposit, to be achieved before the commencement of production.

2024’s first drill campaign was completed at the end of July, totalling 30,170 metres, with the goal of prioritizing key targets for the next drill programme. This first programme successfully confirmed mineralisation at all 14 targets tested. A second 2024 drilling campaign, totalling 60,000 metres, commenced in mid-September and to date has achieved 45,000 meters. Montage remains on track to incorporate the 2024 drilling data into its year-end resource statement, with a maiden mineral resource expected to be published in Q1-2025.

In line with Montage’s goal of unlocking exploration value, the Company expects to conduct similar exploration efforts in 2025, while construction activities are ongoing.

Grant of stock incentives
Given the recent hires, the Company has granted a total of 347,124 Restricted Share Units (“RSUs”) to non-executive team members. The RSUs are granted in accordance with the Company’s 2024 Omnibus Equity Incentive Plan. The RSUs are subject to vesting provisions.
