Ivanhoe Mines Founder and Executive Co-Chair Robert Friedland commented:
"Kamoa-Kakula continues to set records and outperform our expectations, with continued strong performance in terms of throughput, grade and recovery at the Phase 1 and Phase 2 plants. This has all been achieved despite ongoing challenges presented by electrical grid instability, where we now have a plan in place with the Congolese national utility to materially improve reliability across the network for all users over the next year. Meanwhile, the successful connection of the Kamoa 1 and Kansoko underground declines marks a major milestone for the Phase 3 expansion. This achievement demonstrates our commitment to operational excellence and is a testament to our strong partnership with Zijin Mining and the DRC Government. Construction remains on budget and schedule for commissioning by the fourth quarter of 2024, further solidifying our track record of success.
"Ivanhoe Mines is on the cusp of a major turning point in the company's journey, with the conclusion of the Phase 3 expansion expected to mark the commencement of major cash flow and profit for the company. This is an extremely exciting time for Ivanhoe's stakeholders and shareholders as we move forward with our vision of building the world's next major, diversified mining company. We would like to again commend Kamoa Copper's team for continuing to deliver industry-leading results across the operation."

Ball mill components for Kamoa-Kakula's Phase 3 concentrator delivered to site; concentrator execution is now
Kamoa-Kakula's Phase 3 expansion, consisting of two new underground mines known as Kamoa 1 and Kamoa 2 and a new, 5-Mtpa concentrator plant, is well on track for first production in the fourth quarter of 2024. The expansion also includes the integration of Africa's largest direct-to-blister flash smelter, which will have a capacity of 500,000 tonnes of copper per annum and will be constructed on-site at Kakula, adjacent to the existing Phase 1 and Phase 2 concentrator plants.
Associated power and surface infrastructure constructed for Phase 3 expansion will be designed to support future expansions of the Kamoa-Kakula Copper Complex. Underground mining activities are expected to commence at Kamoa 1 in late 2023 and Kamoa 2 in 2025. Both new underground mines will use the same mechanized mining methods employed at the current Kakula mine. In addition, the Phase 3 concentrator will use the same, upscaled process design as that used by the Phase 1 and 2 concentrators.
Installation of the first of the two ball mills has commenced at the Phase 3 concentrator site, which is on track for commissioning in Q4 2024.

Smelter project over
The smelter project is now approximately
Civil construction work is well advanced, with all major foundations for equipment and buildings completed. Most of the structural steel and equipment are now being manufactured. The main mechanical and electrical construction contractors are mobilized. Mechanical erection has started for the direct-to-blister flash furnace and electric slag-cleaning furnace and gas cleaning system. Approximately, 2,000 construction workers are now working at the smelter site and this is expected to peak at 3,000 in December this year.
The Kamoa-Kakula smelter is designed to utilize direct-to-blister flash smelting technology supplied by Metso Outotec of Espoo, Finland, and to meet the world-leading International Finance Corporation's (IFC) emissions standards.
Kamoa-Kakula's Phase 3 expansion includes the refurbishment of turbine #5 at the Inga 2 hydroelectric power station. The turbine will supply an additional 178 megawatts of clean hydroelectric power to the national grid, which is sufficient to meet the power requirements of the Phase 3 concentrator, the DBF flash smelter, as well as provide spare capacity for future expansions. The
