Johannesburg, South Africa--(Newsfile Corp. - October 7, 2025) - Ivanhoe Mines' (TSX: IVN) (OTCQX: IVPAF) Executive Co-Chair Robert Friedland and President and Chief Executive Officer Marna Cloete announced today the company's third-quarter production results and an update on operational and project activities.

During the third quarter, Kamoa-Kakula's Phase 1, 2, and 3 concentrators milled a total 3.46 million tonnes of ore, producing 71,226 tonnes of copper. Copper production year to date totaled 316,393 tonnes. Production guidance of 370,000 tonnes to 420,000 tonnes of copper in concentrate is maintained, with mining of higher-grade areas on the western side of the Kakula Mine expected from mid-November.

Stage Two dewatering activities are over 20% complete, with underground water levels on the eastern side of the Kakula Mine having declined by over 20 metres since the beginning of September. Stage Two dewatering is expected to be completed by the end of November.

Smelter start-up is scheduled to commence in early November, as the installation of a 60 MW uninterruptible power supply (UPS) unit nears completion. The UPS will safeguard the smelter complex from potential power interruptions during the ramp-up period.

Production rates from Kipushi notably improved during the quarter following the completion of the debottlenecking program in August. In the third quarter, the Kipushi concentrator milled a record 168,862 tonnes of ore at an average milled grade of 37.8%, producing a record 57,200 tonnes of zinc in concentrate. The record quarterly production represented a 37% increase compared to Q2 2025.

Phase 1 operations at the Platreef Mine are expected to commence shortly, with the first feed of ore into the concentrator expected in the coming weeks. Project development work on the Phase 2 expansion is already underway, with the appointment of the engineering, procurement and construction management (EPCM) contractor in the fourth quarter. First production from the Phase 2 concentrator is targeted for Q4 2027.

Founder and Co-Chairman Robert Friedland commented:

"Our recovery efforts at the Kakula Mine are advancing well due to exceptional execution from our operating teams under a decisive plan of action put in place by our management team and joint-venture employees. We are on track to restore Kamoa-Kakula towards its previous copper production levels as we rehabilitate the existing workings and develop new high-grade areas across this Tier-One ore body. Insights gathered during the dewatering efforts will be combined with input from our world-class team of independent experts to design an updated mine plan that will chart Kamoa-Kakula's bright future as a leading producer in the copper industry.

"This quarter should mark a turning point in operations, as we anticipate higher grades from Kakula's western side from next month, with selective mining of the existing workings on the eastern side of Kakula planned from Q1 2026. We're also on the cusp of starting operations at Africa's largest and greenest, direct-to-blister copper smelter, which is expected to drive lower cash costs as we complete its ramp-up.

"In addition, we're extremely excited for imminent first production at the Platreef Mine, which is on schedule for later this month. Given rising prices and interest in platinum-group metals, we are bringing the world's next great precious metals complex online at an exceptionally opportune moment. Platreef's major endowment of nickel, copper, and gold makes it one of the lowest-cost and scalable producers of platinum, palladium, nickel, gold, rhodium and copper on our planet ... and we are already at work on a Phase 2 expansion that will propel Platreef into a Top 10 producer globally."

In preparation for the heat-up of Kamoa-Kakula's state-of-the-art, 500,000-tonne-per-annum, direct-to-blister copper smelter, an operator oversees a training exercise on the slag cleaning furnace blister ladles.

Data in red denotes a quarterly record
*Phase 1 & 2 production was impacted in the second quarter by seismic activity at the Kakula Mine as announced on May 20, 2025.

Kakula head grades to improve in Q4 2025 as dewatering activities open up higher-grade mining areas

During the third quarter, the Phase 1, 2, and 3 concentrators milled 3.46 million tonnes of ore, producing 71,226 tonnes of copper. Total copper production year to date is 316,393 tonnes.

As announced on June 11, 2025, mining operations on the western side of the Kakula Mine restarted on June 7, 2025. Since mid-June, the mining rate has increased to an average rate of 350,000 tonnes per month (4.2 million tonnes on an annualized basis). To assist with the increase in the mining rates from the western side of the Kakula Mine, the cut-off grade has been lowered to 1.5% copper (previously 2.0%).

Mining on the western side of the Kakula Mine has been focused on higher-elevation areas in the north and southwest, where copper grades are lower than those of the higher-grade centre, which is currently submerged. From mid-November, mining crews plan to advance towards the centre of the western side of the Kakula Mine, improving head grades to between 3.5% and 4.5%.

The Phase 1 and 2 concentrators will continue to process ore from the western side of the Kakula Mine, as well as surface stockpiles, until Q1 2026, when the stockpiles are depleted. Thereafter, selective mining will commence within the existing workings on the eastern side of the Kakula Mine, which will augment rising production from higher-grade areas on Kakula's western side to underpin improved underground mining rates.

The Phase 3 concentrator milled 1.62 million tonnes of ore in the third quarter, producing 33,522 tonnes of copper. For a second consecutive quarter, the Phase 3 concentrator averaged a milling rate equivalent to 6.5 million tonnes annualized, which is 30% higher than design capacity of 5.0 million tonnes per annum. The average quarterly feed grade for the Phase 3 concentrator was 2.44% copper. The cut-off grade was also lowered to 1.5% copper at the Kamoa Mine to achieve higher mining rates, providing sufficient feed for the Phase 3 concentrator and supplementary feed for the Phase 1 and 2 concentrators. For the foreseeable future, it is expected that the feed grade into the Phase 3 concentrator will continue to average approximately 2.5% copper.

Stage Two dewatering of the Kakula Mine is advancing to plan at over 20% complete

The four Stage Two high-capacity submersible pumps were commissioned over the course of two weeks between the end of August and mid-September. The four pumps are operating at the total design rate of approximately 2,600 litres per second. Including the mobile Stage One pump stations located underground, the total pumping rate at the Kakula Mine, has the potential to pump up to 6,400 litres per second, or 550 megalitres per day, subject to available underground access.

Stage Two dewatering of the Kakula Mine is over 20% complete and is expected to be completed by the end of November 2025, at which point the underground water level is anticipated to be near the bottom of the Stage Two dewatering shafts.

To date, approximately 13 kilometres of lateral development has been rehabilitated. As the water level declines, the mining crews are primarily focused on rehabilitating the access drives required for repositioning the Stage One underground pumping infrastructure, as well as the access towards the Stage Three pump stations, which are currently submerged.

Stage Three pumping will complete the remaining dewatering below the water level accessible by the Stage Two high-capacity submersible pumps, as shown in Figure 1. The mining crews expect to start gaining access to the existing Stage Three pumping infrastructure from November. Each pump station will be refitted and recommissioned with new pump motors and associated electrical infrastructure. Stage Three pumping is expected to be complete in Q1 2026.

Mine planning and scheduling is well advanced to support the ramp-up of underground mining activities from both the Kakula and Kamoa mines, with a medium-term target of returning the milling rate to 17 million tonnes per year, and ultimately targeting annualized copper production of over 550,000 tonnes

Copper production guidance for 2026 and 2027 will be released once sufficient physical inspection of the newly dewatered areas of the Kakula Mine has been completed. The new life-of-mine plan is expected to be released in Q1 2026.

Smelter start-up scheduled for early November; installation nearing completion of 60-megawatt, battery-powered, uninterruptible power supply facility

Heat-up of Kamoa-Kakula's on-site, direct-to-blister copper smelter is expected to commence in early November 2025. Kamoa-Kakula's management team expects to prioritize the processing of all concentrates produced by the Phase 1, 2, and 3 concentrators through the on-site smelter, with any excess concentrate continuing to be toll-treated at the nearby Lualaba Copper Smelter (LCS), in Kolwezi.

The smelter start-up will commence as the installation of the uninterruptible power supply (UPS) facility nears completion later this month. The 60 MW UPS is designed to provide up to 2 hours of instantaneous back-up power to the smelter, protecting the operation from voltage fluctuations in the DRC grid. In addition to the UPS, there is a further 60 MW of dedicated diesel-powered, back-up generator capacity.

There is sufficient on-site copper concentrate inventory for the smelter start-up in early November. As of September 30, 2025, Kamoa-Kakula's unsold copper in concentrate inventory totaled 59,000 tonnes, which includes 7,300 tonnes located at LCS. The first feed of concentrate into the smelter is expected approximately four to six weeks after heat-up commences.

Members of the smelter team are inspecting the sulphuric acid plant ahead of the furnace heat-up. The smelter is expected to produce up to 700,000 tonnes per annum of high-strength sulphuric acid, which is in high demand across the Central African Copperbelt.

Kipushi concentrator produced record 52,700 tonnes of zinc in Q3 2025, following completion of the debottlenecking program, which was delivered under budget and ahead of schedule

Summary of quarterly production data from Kipushi

	Q3 2024	Q4 2024	Q1 2025	Q2 2025	Q3 2025
Kipushi Concentrator
Ore tonnes milled (tonnes)	108,065	119,619	151,403	153,342	168,862
Feed grade of ore processed (% zinc)	32.12	31.72	32.16	33.37	37.81
Zinc recovery (%)	75.78	85.07	87.93	85.22	89.36
Zinc in concentrate produced (tonnes)	18,946	32,490	42,736	41,788	52,700

 

Data in red denotes a quarterly record

Zinc production from the Kipushi concentrator notably improved during the second half of the third quarter, with multiple records achieved. The improvement in production rates was attributed to the completion of the debottlenecking program, as well as upgrades to the dense media separation (DMS) upstream of the concentrator. Both workstreams were completed in August.

Engineering work on the debottlenecking program commenced in September 2024 to boost the concentrator throughput rate by 20% from 800,000 to 960,000 tonnes of ore per annum. The debottlenecking program was completed in early August, both ahead of schedule and under budget. A seven-day planned shutdown of the concentrator to commission the newly installed debottlenecking equipment and upgrades to the DMS circuit was completed in mid-August.

Multiple concentrator records have since been achieved in the latter half of the third quarter. A record 6,064 tonnes of zinc in concentrate were produced over 7 days in late August, equivalent to an annual production rate of over 315,000 tonnes of zinc, after accounting for availability. Sustaining this production rate would make the Kipushi Mine the world's fourth-largest zinc mining operation.

Despite the improved production rates, operations continue to be impacted by grid instability. An additional six megawatts of back-up generator capacity is in the process of being installed and will be commissioned in the coming weeks. The new generators will increase the total onsite back-up power to 20 megawatts, sufficient to maintain operational continuity during periods of grid instability.

In addition to delivering the debottlenecking program ahead of schedule and under budget, the Kipushi project team has done so with an industry-leading safety record. Throughout construction of the Kipushi concentrator, which started in September 2022 and was completed in June 2024, as well as the recently completed debottlenecking program, the project team at Kipushi did not record a single lost time injury (LTI). This is an outstanding and incredibly rare industry achievement.

Total year-to-date production from the Kipushi concentrator is 137,224 tonnes of zinc in concentrate. Following improved production rates from the recently completed debottlenecking program, Kipushi's 2025 production guidance remains unchanged at between 180,000 and 240,000 tonnes of zinc.

First production from Platreef Mine's Phase 1 concentrator is expected in the coming weeks

The Ivanplats project team is almost operationally ready for the first feed of ore into the Platreef Mine's Phase 1 concentrator, which was completed on schedule in June 2024, and has been kept under a regular care and maintenance program. The first feed of platinum-palladium-nickel-gold-rhodium-copper ore into the Phase 1 concentrator is expected by the end of October.

As announced on May 8, 2025, underground development of the thick, high-grade Flatreef platinum-palladium-nickel-gold-rhodium-copper orebody, on the 850-metre level commenced on April 30, 2025. Since then, a total of 165 metres of reef development in ore has been completed, and of the total 17,125 tonnes of ore blasted, 10,215 tonnes of ore have been hoisted to surface. Reef development on the 750-metre level has also recently commenced. Development ore continues to be hoisted to surface via Shaft #1 and stored in surface stockpiles. The development ore stockpiles will feed the 0.8 Mtpa Phase 1 concentrator during the initial stages of ramp-up.

Equipping of Shaft #3 continues to progress well and is on schedule for completion in Q1 2026. Long hole stoping (production mining) is expected to commence in Q2 2026, once Shaft #3 is commissioned and is ready to hoist.

The underground delineation drilling program, which commenced last year ahead of developing the first long hole ore blocks, has progressed very well with a total of 16,110 meters drilled to date. All assays reconcile well with Ivanplats' geological models and mine plan.

Recruitment continues ahead of the ramp-up of Phase 1, with a total Ivanplats workforce now at over 2,200 employees and contractors, including more than 70% locally-based and 26% female. The workforce will continue to grow as the project team has recently started development work on Phase 2.

Project development on Phase 2 expansion underway, targeting completion in Q4 2027

The Ivanplats project engineering team has already commenced work on the development of Phase 2, with the concentrator expansion targeted for completion in Q4 2027. The EPCM contractor for the 3.3-million-tonne-per-annum Phase 2 concentrator is also expected to be appointed in Q4 2025, with earthworks on the site adjacent to the Phase 1 concentrator scheduled to commence shortly thereafter.

In addition, Shaft #2's concrete headgear is now completed, and the expansion of the shaft to a diameter of 10 metres will commence following the appointment of the contractor in Q1 2026. Raise boring of Shaft #2 to its initial diameter of 3.1 metres was completed in Q4 2024.
