RIYADH, SAUDI ARABIA – Ivanhoe Mines (TSX: IVN; OTCQX: IVPAF) Executive Co-Chair Robert Friedland announced today, ahead of the inaugural Future Minerals Forum, that the 2022 annual production guidance for the Kamoa-Kakula Copper Complex in the Democratic Republic of Congo (DRC) is between 290,000 and 340,000 tonnes of copper in concentrate.
The figures are on a 100%-project basis and metal reported in concentrate is prior to refining losses or deductions associated with smelter terms.
The guidance range for cash costs (C1) per pound of payable copper in 2022 is between $1.20 and $1.40 per pound of payable copper. Cash costs (C1) per pound of payable copper for Q3 2021 totaled $1.37/lb, while cost of sales per pound of payable copper sold for Q3 2021 was $1.08/lb. "Cash costs (C1) per pound" is a non-GAAP financial performance measure. Additional information is provided in the Non-GAAP Financial Performance Measures section of this news release.
Kamoa Copper’s copper-in-concentrate production for the year ended December 31, 2021, totalled 105,884 tonnes, exceeding the upper end of the increased guidance range of 92,500 to 100,000 tonnes. The year-end total was boosted by record monthly production of 18,853 tonnes achieved in December.
2021 guidance had been raised from an initial range of 80,000 to 95,000 tonnes, during the course of the successful ramp-up of Kamoa Copper’s Phase 1 concentrator plant, which began operations in late May 2021 and reached commercial operations on July 1, 2021.
During the month of December, a record 372,000 tonnes of ore were milled at an average feed grade of 5.98% copper, exceeding the monthly design run rate of 316,667 tonnes by more than 17%.
Copper flotation recoveries also achieved a record 88.5% in December. The Phase 1, steady-state design copper recovery is approximately 86%, depending on ore feed grade.
Kamoa Copper expects to begin operations at the Phase 2concentrator plant in Q2 2022. The Phase 2 concentrator plant is identical to the Phase 1 concentrator, with a nameplate milling capacity of 3.8 million tonnes per annum (Mtpa), and a similar ramp-up profile for the new concentrator is targeted, with the benefit of additional knowledge gained during the commissioning of Phase 1.
The Phase 3 expansion also is advancing, with work ongoing on new box cut to open up the Kamoa Mine. An updated pre-feasibility study (PFS), including the Phase 3 expansion, is expected in Q3 2022.

2022 Guidance for Kamoa-Kakula
Guidance is based on a number of assumptions and estimates as of December 31, 2021, including among other things, assumptions about the timing of the Phase 2 expansion and anticipated costs and expenditures. Production and cost guidance assumes the Phase 2 concentrator plant will commence copper production in Q2 2022 and that ramp-up will be in line with what was achieved with Phase 1. Guidance involves estimates of known and unknown risks, uncertainties and other factors which may cause the actual results to be materially different.
Kamoa-Kakula 2022 Guidance
Contained copper in concentrate (tonnes)
290,000 - 340,000
Cash cost (C1) ($ per pound)
1.20 - 1.40
Cash costs (C1) per pound of payable copper for Q3 2021 of $1.37/lb reflected the measured ramp-up of production at Kamoa-Kakula to steady-state, and are expected to trend downward as the Phase 2 concentrator plant is commissioned and the mine’s fixed operating costs are spread over increased copper production.
C1 cash cost is a non-GAAP measure used by management to evaluate operating performance and include all direct mining, processing, and general and administrative costs. Smelter charges and freight deductions on sales to final port of destination (typically China), which are recognized as a component of sales revenues, are added to C1 cash cost to arrive at an approximate cost of delivered finished metal.
Cost of sales per pound of payable copper sold for Q3 2021 was $1.08/lb. For historical comparatives see the Non-GAAP Financial Performance Measures section of this news release. Please also see the Management’s Discussion and Analysis for the three and nine months ended September 30, 2021, for discussion of non-GAAP measures. All figures in the above table are on a 100%-project basis.
“Kamoa Copper’s outstanding operational success in 2021 is a product of the culture and values promoted throughout the organization,” said Mr. Friedland. “We are focused on training and empowering our young, talented Congolese workforce to operate this globally significant copper mining and smelting complex for generations to come. We invest deeply in our people and we celebrate their diversity, as diversity is a core value and a key to our strength. Collectively we are determined to create long-term stakeholder and shareholder value through continued investment in discovering and developing world-class orebodies, technological innovation, strong corporate governance, environmental stewardship, empowering our host communities and intense focus on health and safety.
“The Phase 2 expansion remains significantly ahead of schedule, and we are well on the way to doubling our annualized copper production to more than 400,000 tonnes starting early in Q2 2022, vaulting Kamoa Copper into the ranks of the world’s ten largest copper mines.
“Our outstanding team of geologists are confident that the Kamoa and Kakula mines are just the initial discoveries of a major new mining district, which extends the storied African Copperbelt in a southwesterly direction all the way to the Zambian border. We will be conducting an extensive drilling campaign on our majority-owned Western Foreland exploration licences this year to unlock the potential of this highly-prospective ground.”

Phase 2 expansion now 80% complete, expected to start operations in Q2 2022
Construction of the second 3.8-Mtpa concentrator plant (Phase 2) continues to progress ahead of schedule with hot commissioning expected to start in Q2 2022. Engineering, procurement and fabrication activities all are effectively complete, with construction activities well advanced. As of the end of December, the overall project was approximately 80% complete. Some pre-commissioning activities have started.
The main construction focus now has shifted from structural steel erection and installation of platework, equipment and piping (SMPP) to electrical, control and instrumentation (EC&I) installation. Most areas have been handed over from the SMPP contractor to the EC&I contractor.All of the Phase 2 surface piping has been installed. Installation of cable racking is nearing completion and cable pulling and instrument installation is well advanced.
More than 675 truckloads of Phase 2 plant construction equipment and materials already have been delivered to site.
Updated PFS study, including Phase 3 expansion, expected in Q3 2022; work on new box cut to open up the Kamoa Mine advancing
Kamoa Copper also is advancing the Phase 3 expansion, with operations at the first stream of the Phase 3 concentrator expected by the end of 2024. The Phase 3 concentrator will be located adjacent to the Kansoko Mine (at the Kansoko Sud orebody) and is being designed as two identical streams with a common dry front end, the same as the Phase 1 and 2 concentrators, but at a larger nameplate milling capacity per stream than the 3.8-Mtpa capacity of the Phase 1 and 2 concentrators.
The Phase 3 concentrator is expected to be supplied with ore from the established mine at Kansoko, as well as from two new planned mines, named Kamoa 1 and Kamoa 2. The Kamoa 1 and Kamoa 2 mining areas will be accessed via a twin-decline system (the Kamoa Mine decline), and the box cut for the declines is under construction.
Phase 3 also includes the construction of a direct-to-blister smelter, with a production capacity of 500,000 tonnes per annum of blister copper. Basic engineering, led by China Nerin Engineering Co., Ltd. of Jiangxi, China, is ongoing and expected to be completed in Q2 2022.
The planned smelter is to be built adjacent to the Phase 1 and 2 concentrator plants, and is designed to meet the International Finance Corporation’s emissions standards. The smelter has been sized to process the majority of the copper concentrate forecast to be produced by Kamoa-Kakula’s Phase 1, Phase 2 and Phase 3 concentrators. With a nameplate capacity of 500,000 tonnes per annum of blister copper, it is projected to be one of the largest, single-line blister-copper flash smelters in the world, and the largest in Africa.
Power for the Phase 3 expansion will be supplied by the upgrading of turbine 5 at the Inga II hydropower complex to provide an additional 162 megawatts (MW) of renewable hydropower. Basic engineering for the design of a new turbine wheel and runners is ongoing at the Heidenheim offices of contractor Voith Hydro, and the contractor’s team is preparing to mobilize on site.
Study work on all aspects of the Phase 3 expansion is progressing well, with further information to be provided in Q2 2022 as estimates are completed, and an updated PFS expected to be released in Q3 2022.
Mining crews produce 756,000 tonnes grading 5.25% copper from the Kakula and Kansoko mines in December
Underground mine production from the Kakula and Kansoko mines was 756,000 tonnes grading 5.25% copper from November 21st to December 31st, including 272,000 tonnes grading 6.53% copper from the Kakula Mine’s high-grade centre and 77,600 tonnes grading 4.15% copper from the Kansoko Mine. The production measuring month was longer than normal in order to close out the year.
Production levels from the mine are well above target, and will be boosted by three additional underground ore trucks commissioned on December 28, 2021.
The project’s surface stockpiles now contain approximately 4.19 million tonnes of high-grade and medium-grade ore at an estimated, blended average of 4.63% copper. Contained copper in the stockpiles at the end of December now totals more than 194,000 tonnes (the current copper price is approximately $9,600 per tonne).

About the Kamoa-Kakula Copper Complex
Kamoa-Kakula is projected to be the world’s highest-grade major copper complex, with an initial mining rate of 3.8 Mtpa at an estimated, average feed grade of more than 6.0% copper over the first five years of operations, and 5.9% copper over the initial 10 years of operations. Phase 1 is expected to produce approximately 200,000 tonnes of copper per year, while the Phase 2 expansion is forecast to increase production to more than 400,000 tonnes of copper annually.
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.

沙特阿拉伯利雅得 — 艾芬豪矿业 (TSX: IVN; OTCQX: IVPAF) 执行联席董事长罗伯特·弗里兰德 (Robert Friedland) 今天在首届未来矿业论坛 (Future Minerals Forum) 开幕前宣布，公司位于刚果民主共和国 (以下简称“刚果(金)”) 的卡莫阿-卡库拉铜2022年的生产指导目标为290,000至340,000吨铜金属。
2022年每磅铜的C1现金成本的指导目标为1.20 ~ 1.40美元/磅。2021年第三季度的C1现金成本为1.37美元/磅，按会计准则计算的销售成本则为1.08美元/磅。“每磅现金成本 (C1) ”为非公认会计准则 (non-GAAP) 的财务指标。详细说明，请参阅本新闻稿中 “非公认会计准则财务指标” 的部分。
截至2021年12月31日止年度，卡莫阿铜矿共生产精矿含铜金属量达105,884 吨，超越上调后的生产指导目标 (92,500至100,000吨) 的上限。12月份铜产量破纪录达18,853吨，显著提升了年终总产量。
III期扩建工程进展顺利，新斜坡道入口的建设施工顺利，将拓展卡莫阿 (Kamoa) 矿山的采矿范围；预可行性研究更新版将涵盖III期扩建计划，预计于2022年第三季度发布。
290,000 - 340,000
1.20 - 1.40
“我们杰出的地质师团队相信，卡莫阿和卡库拉 (Kakula) 矿山只是早期发现，大型矿集区将扩大中非铜矿带的范围，向西南一直延伸至赞比亚边境。今年，我们将在公司持有多数股权的西部前沿 (Western Foreland) 探矿权內进行广泛的钻探活动，全面释放这遍土地的巨大勘探潜力。”
主要施工重点已从钢结构以及钣金、设备和管道 (SMPP) 的安装转移至电器、控制和仪表 (EC&I) 的安装。多个厂区已由SMPP承包商移交给EC&I承包商。II期的所有地表管道已安装完成。电缆的安装工作快将完成，且布线和仪表的安装正顺利进行。
超过675辆装载 II 期工程设备和材料的卡车已抵达现场。
同时，卡莫阿铜矿正在推进III 期扩建工程，预计III期选厂的第一流程将于2024年底开展作业。III 期选厂将建设在卡索科 (Kansoko) 矿山，设计与I 期和II 期选厂相同，设有两条相同的流程和前端工艺。III 期选厂的设计产能，将会高于 I 期和 II 期选厂的380万吨/年。
预计 III 期选厂将处理采自卡索科的矿石以及规划中的两座矿山 — 卡莫阿一区和卡莫阿二区的矿石。施工中的卡莫阿矿山双斜坡道系统将用于卡莫阿一区和卡莫阿二区的采区进场通道，现正进行斜坡道井口的建设工程。
规划中的冶炼厂将建设在I期和II期选厂附近，按照国际金融公司 (IFC) 制定的排放标准建造。冶炼厂的规模设计适合处理卡莫阿-卡库拉I期、II期和III期选厂生产的大部分铜精矿，预计将会成为全球规模最大的单系列直接粗铜闪速冶炼厂之一以及非洲最大型的铜冶炼厂。
英加二期水电站5号涡轮机组升级改造后，将为III期扩建提供额外的162兆瓦可再生水电。承包商福伊特水电 (Voith Hydro) 在海登海姆办事处的人员正进行新涡轮和转轮的基础工程设计，工作团队正准备前往现场。
预计卡莫阿-卡库拉将成为全球品位最高的大型铜矿山，初始年处理矿石380万吨，预计投产后前5年的平均入选铜品位超过6.0%，投产后前10年超过5.9%。I 期投产后预计每年将生产约20万吨铜，II 期扩建投产后每年将累计生产高达40万吨铜。
卡莫阿-卡库拉铜矿项目是艾芬豪矿业 (占股39.6%)、紫金矿业集团 (占股39.6%)、晶河全球 (占股0.8%) 及刚果民主共和国政府 (占股20%) 的合资项目。 2020年，加拿大Hatch有限公司对卡莫阿-卡库拉的温室气体强度指标进行了独立审核，确认项目将会成为全球单位铜温室气体排放最低的矿山之一。
C1现金成本及每磅C1现金成本为非公认会计准则的财务指标。这些披露使投资者更清楚了解卡莫阿-卡库拉项目的表现，与其他铜生产商按照类似指标公布的业绩作比较。C1 现金成本的计算基准与伍德曼肯兹成本指南制定的行业标准定义一致，但并非国际财务报告准则 (IFRS) 认可的计量。
