KOLWEZI, DEMOCRATIC REPUBLIC OF CONGO – Ivanhoe Mines (TSX: IVN; OTCQX: IVPAF) Co-Chairs Robert Friedland and Yufeng “Miles” Sun announced that Kamoa Copper has approved a de-bottlenecking plan for Kamoa-Kakula to increase the combined design processing capacity of the Phase 1 and Phase 2 concentrator plants by approximately 21%, to 9.2 million tonnes of ore per year (Mtpa), up from 7.6 Mtpa, once steady-state production is achieved at both concentrators.
The de-bottlenecking initiative is expected to increase Kamoa-Kakula’s Phase 1 and Phase 2 annual copper output to more than 450,000 tonnes by Q2 2023 ─ positioning Kamoa-Kakula as the world’s fourth largest copper producer.
Mark Farren, Kamoa Copper’s CEO, said: “Kamoa-Kakula is blessed with an incredible endowment of high-grade copper resources. Given that our underground mine development and ore production are both progressing well ahead of schedule, the plant expansion will allow the operations team to process significantly more high-grade copper ore directly from the Kakula Mine in the years ahead.
“Our orebody has a huge advantage in allowing us to adapt our mining cut-off to mine larger tonnages very efficiently, while maintaining grades above a desired level. The expansion also provides the team with the flexibility to utilize our surface stockpiles, for which the mining is already paid for, that totalled more than 4.4 million tonnes grading 4.61% copper at the end of January.”
Construction of Kamoa-Kakula’s Phase 2, 3.8-Mtpa concentrator plant almost is complete with early-stage commissioning activities now underway. Hot commissioning of the concentrator with first ore and initial copper concentrate production are both on track for April 2022.
Engineering and early works for the Phase 3 expansion, including a new box cut and twin declines to access new mining areas, is progressing quickly. A third, significantly larger concentrator is being designed and is expected to commissioned in Q4 2024. An updated pre-feasibility study, including the Phase 3 expansion, is expected in Q3 2022. Also underway are early works on a direct-to-blister flash smelter at Kamoa-Kakula that will incorporate leading-edge technology supplied by Metso Outotec of Finland, and have a nameplate capacity of 500,000 tonnes a year of approximately 99%-pure blister copper.
The Phase 1 concentrator currently is running at a throughput that is in excess of its 3.8-Mtpa design capacity by more than 22%, with 112% of design throughput achieved in January. Copper recoveries of above 87% also are consistently being achieved that are in excess of design recovery of 85.6%, depending on feed grade, with January’s recoveries approximately 2.7% higher.
Despite the Phase 1 concentrator incurring significant downtime for critical tie ins and changes required for the commissioning of the Phase 2 concentrator, the copper in concentrate produced in January totalled 18,824 tonnes ─ almost the same as December’s record production of 18,853 tonnes. January’s impressive operating performance of the Phase 1 concentrator is continuing in February. On February 7th, the concentrator set a new daily ore throughput record with13,498 tonnes milled.

Steve Amos, Ivanhoe Mines’ Head of Projects, DRC, commented: “After successfully operating the Phase 1 concentrator for more than eight months, we’ve identified a number of relatively minor modifications to the concentrator that should increase ore throughput from the current design of 475 tonnes per hour to 580 tonnes per hour. These modifications include increasing the diameter of a number of pipes, replacing a number of motors and pumps with larger ones and installing additionalflotation, concentrate-thickening, concentrate-filtration and tailings-disposal capacity.
“We expect the de-bottlenecking project to cost approximately US$50 million and take approximately 12 months to complete.These modifications will allow the team to consistently operate the concentrator plant at the increased throughput without compromising plant availability, copper recovery or copper concentrate grade. Engineering design is under way and procurement of long-lead items already has started. We expect to be in a position to increase Kamoa-Kakula’s combined processing capacity to 9.2 million tonnes of ore a year by Q2 2023.”
As announced earlier this year, the 2022 production guidance for the Kamoa-Kakula Copper Complex is between 290,000 to 340,000 tonnes of copper in concentrate. The figures are on a 100%-project basis and copper reported in concentrate is prior to refining losses or deductions associated with smelter terms.

About the Kamoa-Kakula Copper Complex
Kamoa-Kakula is the world’s fastest growing major copper mine. Kamoa-Kakula began operations in May 2021 and produced approximately 106,000 tonnes of copper in concentrate in 2021. Kamoa-Kakula’s 2022 production guidance is between 290,000 to 340,000 tonnes of copper in concentrate.
Based on independent benchmarking, the project’s phased expansion scenario to 19 Mtpa would position Kamoa-Kakula as the world’s second-largest copper mining complex, with peak annual copper production of more than 800,000 tonnes.
The Kamoa-Kakula Copper Project is a joint venture between Ivanhoe Mines (39.6%), Zijin Mining Group (39.6%), Crystal River Global Limited (0.8%) and the Government of the Democratic Republic of Congo (20%). A 2020 independent audit of Kamoa-Kakula's greenhouse gas intensity metrics performed by Hatch Ltd. of Mississauga, Canada, confirmed that the project will be among the world's lowest greenhouse gas emitters per unit of copper produced.

刚果民主共和国科卢韦齐 — 艾芬豪矿业 (TSX: IVN; OTCQX:IVPAF) 联席董事长罗伯特·弗里兰德 (Robert Friedland) 与孙玉峰 (Miles Sun) 欣然宣布，卡莫阿铜业已批准一项技改计划，旨在扩大卡莫阿-卡库拉 (Kamoa-Kakula) I期和II期选厂的设计产能。达到稳产后，总设计产能将从760万吨/年提升约21%至920万吨/年。
卡莫阿铜业首席执行官马克·法伦 (Mark Farren)表示﹕"卡莫阿-卡库拉蕴藏着无与伦比的高品位铜资源。地下开拓和采矿工程正超计划推进，选厂扩产将使运营团队直接处理来自卡库拉矿山的高品位矿石，大大提升选矿产能。矿体的巨大优势，使我们能够高效地调整采矿边界品位以增加采矿量，同时确保品位高于理想水平。选厂扩产带来的灵活性，使得我们能够充分利用地表矿堆。截至1月底，地表矿堆量累计已超过440万吨，铜品位4.61%。"
III期扩建的工程设计和前期工作进展迅速，其中包括兴建新采区进场通道的井口和双斜坡道。第三座选厂规模更为庞大，目前正进行设计工作，预计于2024年第四季度实现投产。更新版预可行性研究将涵盖III期扩建计划，预计于2022年第三季度发布。卡莫阿-卡库拉直接粗铜冶炼厂的前期工作正进行中，将融合芬兰美卓奥图泰 (Metso Outotec) 公司提供的尖端技术，设计产能达每年50万吨99%粗铜。
