"considered, by virtue of his education, experience, and professional association, a Qualified Person under the terms of NI 43-101."

A Canadian regulatory standard that sets the rules for how mining and exploration companies must report mineral resources and reserves, requiring technical reports prepared or signed off by an independent, certified expert. It matters to investors because it creates a consistent, transparent “inspection report” for mining projects, making it easier to compare prospects, judge the reliability of claims, and assess geological and financial risk before investing.

qualified person regulatory

"considered, by virtue of his education, experience, and professional association, a Qualified Person under the terms of NI 43-101."

A qualified person is someone with specialized knowledge, experience, and training in a particular field, allowing them to accurately assess and verify information or work. Their expertise helps ensure that reports, evaluations, or decisions are trustworthy and meet required standards. For investors, a qualified person provides confidence that the information they rely on is credible and properly validated.

cash cost (C1) financial

"Cash cost (C1) guidance for 2026 will be provided with the 2025 full-year financial results"

Cash cost (C1) is a per‑unit measure commonly used by resource and mining companies that shows the direct, out‑of‑pocket expenses to produce one unit of output (for example, one ounce of metal). It typically covers immediate costs like extraction, processing and onsite operating expenses but excludes bigger or non‑cash items such as exploration, sustaining capital, and some taxes or royalties. Investors use C1 to gauge day‑to‑day operational efficiency and short‑term profitability — like knowing the grocery cost to make a single meal versus long‑term household expenses — and to compare how cheaply different producers can make the same product.

2026 copper sales expected to exceed production as surplus concentrate inventory at smelter is cleared; first feed is expected at the end of December

Medium-term annualized copper production target maintained at 550,000 tonnes

Kakula Mine Stage 2 dewatering progressing well at over 60% complete; high-capacity submersible pumps lowered to continue dewatering efforts

Johannesburg, South Africa--(Newsfile Corp. - December 3, 2025) - Ivanhoe Mines (TSX: IVN) (OTCQX: IVPAF) Executive Co-Chairman Robert Friedland and President and Chief Executive Officer Marna Cloete announce today Kamoa-Kakula's copper production guidance for 2026 and 2027, as well as an update on the Kakula Mine's dewatering activities.

Dewatering of the Kakula Mine is progressing well, with dewatering approximately 70% complete on the western side of the mine and 60% complete on the eastern side. To date, 13.4 kilometres of underground workings have been rehabilitated and made safe for resumption of operations, including 4.6 kilometres which were dewatered.

Positive progress to date on underground rehabilitation, along with ongoing mine planning, provides Kamoa-Kakula's management team with sufficient confidence to issue copper production guidance of 380,000 to 420,000 tonnes for 2026 and 500,000 to 540,000 tonnes for 2027. Kamoa-Kakula is still targeting medium-term production of approximately 550,000 tonnes. An updated life-of-mine plan for Kamoa-Kakula is on target for completion in late Q1 2026.

Following the commencement of the Kamoa-Kakula Copper Smelter as announced on December 1, 2025, copper sales in 2026 are expected to be higher than copper production as the on-site inventory of unsold copper concentrate is destocked by approximately 20,000 tonnes of copper.

Ivanhoe Mines Founder and Executive Co-Chairman Robert Friedland commented:

"The turnaround at Kamoa-Kakula is advancing with confidence. Even during the recovery years of 2025 and 2026, this remarkable copper complex is set to produce approximately 400,000 tonnes of copper … an extraordinary testament to the quality of Kamoa-Kakula's world-leading natural endowment. As we move through this transition and into the next phase of growth in the coming years, Kamoa-Kakula and the Western Forelands will become one of the largest, if not the largest, copper complexes in the world. Our stakeholders are blessed with a Tier-One mining complex that will operate for generations to come.

"We are also on the cusp of a transformational change for Kamoa-Kakula and the Democratic Republic of the Congo as we transition from producing copper in concentrate in huge volumes, to producing copper anodes for sale to consumers all over the world, at our own smelter complex, the largest in Africa."

Ivanhoe Mines President and Chief Executive Officer Marna Cloete commented:

"We extend our deepest gratitude to the entire team at Kamoa-Kakula for their unwavering dedication throughout the dewatering and rehabilitation of the Kakula Mine. They have worked under pressure, and done so with discipline, resilience, and an unshakable commitment to doing things the right way. Most importantly, they have carried out this demanding work with an outstanding focus on safety. Their dedication and professionalism are the foundation of our progress, and we are extremely proud of their achievements."

Kakula copper grades improving as dewatering activities re-open higher-grade mining areas

The revised Kakula mine design has been developed based on geotechnical expert guidance, including new pillar designs and extraction sequencing.

Mining rates on the western side of Kakula have increased to an average rate of 350,000 tonnes per month, equivalent to 4.2 million tonnes (Mt) annualized.

Mining activities have been focused on higher-elevation areas in the north and southwest, where copper grades are lower than those of the higher-grade centre section. As water levels on the western side recede, mining crews are advancing towards the high-grade centre section, where grades increase to between 3.5% and 4.0% from mid-December.

Mining rates at Kakula are expected to improve gradually through 2026. Selective mining within the existing workings on the eastern side of the Kakula Mine is expected to start in Q1 2026, augmenting rising production rates from higher-grade areas on Kakula's western side. This is expected to increase production rates to 450,000 tonnes per month, or 5.5 Mtpa annualized, by the end of the quarter. In addition, underground development towards a new mining area further to the east is expected to begin mining ore from mid-year 2026.

Approximately 6 Mt of ore is expected to be mined at Kakula during 2026, which is expected to increase to between 7 and 8 Mt during 2027. Grades are expected to range from 3.5% to 4.5% during this period. Approximately 70% of the ore will be sourced from the western side of the Kakula Mine during 2026, which will reduce during 2027 as new mining areas on the eastern side are opened up. All ore mined from the Kakula Mine will be processed by the Phase 1 and 2 concentrators.

Mining rate of the Kamoa mines targeted to increase to 10 million tonnes per annum in 2027, filling the Phase 3 concentrator and supporting the Phase 1 and 2 concentrators

The combined annualized mining rate of Kamoa 1, Kamoa 2 and Kansoko underground mines (the Kamoa mines) is targeted to increase from approximately 6.5 Mt currently, to approximately 8.5 Mt in 2026 and to over 10 Mt in 2027. Grades from the Kamoa mines are expected to average approximately 2.5% during this period.

Increased mining rates will be supported by a newly commissioned belt at Kamoa 1, new mine accesses at Kansoko Sud to improve efficiency and new mine accesses at Kamoa 2 to increase the number of underground crews. Mining efficiency is also expected to improve through increased end availability and redundancy, as well as other productivity enhancements.

The Kamoa mines are operating in accordance with similar geotechnical expert guidance, incorporating learnings from Kakula.

The increased mining rate will enable the Kamoa mine to feed the Phase 3 concentrator and provide supplementary feed to the Phase 1 and 2 concentrators, as shown in Figure 1.

Total processing capacity of Phase 1, 2 and 3 concentrators to reach 17 million tonnes per annum from 2027

The Phase 1 and 2 concentrators will continue to process ore from the western side of the Kakula Mine and surface stockpiles until Q1 2026 when the stockpiles are depleted. In addition, from Q1 2026, Phase 1 and 2 will be supplemented with an increasing quantity of ore from the eastern side of Kakula, as well as ore trammed from Kamoa.

In 2026, approximately 2 Mt of ore from Kamoa is expected to be processed by the Phase 1 and 2 concentrators. In 2027, this is expected to increase to 2.5 Mt.

The Phase 1 and 2 concentrators have demonstrated combined operating capacity of 10.5 Mtpa, or 5.25 Mtpa per line, since various de-bottlenecking activities were completed.

The Phase 3 concentrator will continue to process at a rate of 6.5 Mt per annum, which has also been demonstrated over many months of operations, fed by the Kamoa mines.

The recoveries of the Phase 1 and 2 concentrators are expected to improve following the completion of Project 95 in Q2 2026, after which recoveries are expected to increase to approximately 95% over time. A similar capital project to increase copper recoveries from Phase 3 to approximately 92% is under consideration but not included in the 2026 or 2027 production profile.

Updated life-of-mine integrated development plan on track for Q1 2026; targeting return of annualized copper production to approximately 550,000 tonnes

Work is advancing on track for the updated life-of-mine integrated development plan to be completed by end of Q1 2026. The plan includes a full review of both the Kakula and Kamoa life-of-mine plans, based on Phase 1, 2 and 3 at a processing rate of 17 million tonnes per annum, prior to the Phase 4 expansion. The study will also include an expansion scenario for Phase 4, intended to increasing processing capacity by 6.5 Mt per annum by constructing a duplicate of the Phase 3 concentrator.

Production rates are expected to steadily improve as the Kakula Mine recovery plan is completed, and annualized copper production expected to return to approximately 550,000 tonnes over the medium and long term.

Kakula Mine Stage 2 dewatering progressing well at over 60% complete; high-capacity submersible pumps lowered to continue dewatering efforts

As announced on September 18, 2025, Stage 2 dewatering activities have been underway since early September, when two pairs of high-capacity submersible pumps, with a combined capacity of 2,600 litres per second were installed and commissioned in under six weeks.

Dewatering activities successfully split the flooded areas into discrete western and eastern zones during the month of November. Dewatering from the western side of the mine is 70% complete (measured by total volume of water) as at the start of December and is expected to be fully completed by the end of January by Stage 3 (steady-state) dewatering.

Stage 3 dewatering consists of re-commissioning the existing, water-damaged underground horizontal pump stations which are used during steady-state operations. The rehabilitation work consists of fitting new pump motors, substations and electrical cabling. All the required equipment is on site, and the installation work will take place once access to the horizontal pump stations becomes available. To date, approximately 800 litres per second of Stage 3 pumping capacity has been re-established. Access to an additional 800 litres per second of pumping capacity is expected by year end, with access to a further 600 litres per second of pumping capacity expected in January 2026.

On the eastern side of the mine, Stage 2 dewatering is 60% complete. The first pair of pumps (Pumps 3 and 4) ran dry during the last week of November, as planned, with the water level declining by a total of 38 metres, or approximately 84% from the initial water level measurement. Following an underground survey, Pumps 3 and 4 were repositioned lower by up to 19 metres to enable pumping to continue for a further 3 weeks.

The second pair of pumps (Pumps 1 and 2), which were installed in a deeper section of the mine, as shown in Figure 2, have reduced the water level by 45 metres, or approximately 48% from the initial measurement. Pumps 1 and 2 are expected to continue operating into Q1 2026, as Stage 3 dewatering is ramped up.

Over 2,200 megalitres of water lie below the level of the Stage 2 dewatering pumps, which will be pumped out gradually using the Stage 3 dewatering infrastructure. This existing flooded mine area is not on the critical path for ramping up mining rates on the eastern side of the Kakula Mine, which will be focused on a new mining area on the east beyond a barrier pillar. Future mining will be de-risked by dewatering in advance of the working face, using similar technology to the Stage 2 dewatering system.

2026 & 2027 COPPER PRODUCTION GUIDANCE

Kamoa-Kakula Production Guidance
2026 contained copper (tonnes)	380,000 - 420,000
2027 contained copper (tonnes)	500,000 - 540,000

Guidance figures are on a 100% project basis.

Kamoa-Kakula's 2026 and 2027 production guidance is based on several assumptions and estimates. It involves estimates of known and unknown risks, uncertainties, and other factors that may cause the actual results to differ materially.

The 2025 production guidance was revised on June 11, 2025 following the seismic activity as reported on May 20, 2025, and associated interruptions in mining operations at the Kakula Mine. The Kamoa-Kakula Copper Complex produced 316,395 tonnes of copper in concentrate for the nine months ended September 30, 2025 and is on track to meet revised full-year guidance of 370,000 to 420,000 tonnes of copper.

Although mining on the western side of the Kakula Mine has restarted, risk factors remain, including the integrity of underground infrastructure once dewatering is complete, the ability to ramp up underground operations, the ability to complete dewatering activities, and the time required to access the new mining areas. The updated 2026 and 2027 production guidance ranges for Kamoa-Kakula are based on an assessment of these factors that management believes are reasonable at this time, given all available information.

Kamoa-Kakula's adjusted 2025 and 2026 capital expenditure guidance, as announced on October 29, 2025 remains unchanged. Cash cost (C1) guidance for 2026 will be provided with the 2025 full-year financial results in February 2026.
