KOLWEZI, DEMOCRATIC REPUBLIC OF CONGO – Ivanhoe Mines (TSX: IVN; OTCQX: IVPAF) Co-Chairs Robert Friedland and Yufeng “Miles” Sun are pleased to announce accelerated construction and commissioning progress at the Phase 1 Kamoa-Kakula concentrator plant. The target date for C4 commissioning (milling of ore and first copper concentrate production) has been advanced to the end May or early June –several months ahead of schedule.
Overall construction of the project’s first phase 3.8-Mtpa concentrator plant is essentially complete, with the majority of the C1 (construction complete) certificates signed off. The plant is energized with permanent power and C2 commissioning, which involves electrical, control and instrumentation checks, is well advanced. Water is being circulated in certain areas of the plant, marking the beginning of C3 commissioning. C3 commissioning involves checking for leaks, certain instrument calibration, control loop checks, and is the precursor to C4 commissioning (hot commissioning), which involves processing ore through the plant to produce a copper concentrate.
Overall plant commissioning is running well ahead of schedule, with the first ore expected to be added to the mill by the end of May 2021. Lower-grade ore will be fed into the plant during the C4 commissioning phase, to ensure plant performance and copper recovery are satisfactory before increasing the head grade.
The 409,000 tonnes mined in April comprised 357,000 tonnes grading 5.70% copper from the Kakula Mine, including 121,000 tonnes grading 8.40% copper from the mine’s high-grade centre, and 51,000 tonnes grading 5.85% copper from the Kansoko Mine.
The project’s pre-production surface stockpiles now contain approximately 3.0 million tonnes of high-grade and medium-grade ore at an estimated blended average of 4.74% copper. Kamoa-Kakula now has reached the 3.0-million-tonne target of mined high-grade and medium-grade ore, several months ahead of the timeline estimated in the 2020 pre-feasibility study.
Contained copper in the stockpiles increased by approximately 23,000 tonnes in April – to a cumulative total of more than 140,000 tonnes (the current copper price is approximately US$9,950 a tonne).
Some of the approximately 7,000 employees and contractors who helped to build the Phase 1, 3.8-Mtpa concentrator plant ahead of schedule and within budget.
April’s underground mine development shatters all previous records with advancement of more than 3,625 metres
Kamoa-Kakula also set another monthly mine development record in April, with an advancement of more than 3,625 metres, bringing total underground development to approximately 42.2 kilometres – more than 15 kilometres ahead of schedule.
Drift-and-fill stoping operations are progressing well at the Kakula Mine, with the majority of the ore production coming from stoping operations and the remainder coming from mine development activities. Drift-and-fill stoping is a highly-productive mining method of extracting underground ore, where a single tunnel, known as a stope, is extracted leaving an open void that is subsequently backfilled to allow for the extraction of the neighbouring stope in sequence. The backfill plant, which will mix tailings from the processing plant with cement to produce paste backfill, will begin pumping backfill to the underground operations in July.
Mark Farren, Kamoa Copper’s CEO, remarked: “April was another month of great performance by our mining teams, who continue to produce well above plan. We now have reached our 3.0-million-tonne pre-production stockpile target. This stockpile likely is to grow further as our monthly mining rate currently exceeds the Phase 1 milling rate, and only should be drawn down once the Phase 2 concentrator begins operation in mid-2022.
“Even more exciting is the fact that we have been able to significantly bring forward the Phase 1 concentrator commissioning. We now expect to produce our first copper concentrate by the end of May or early June, months ahead of the original schedule.
“We have fantastic people on site, who continue to achieve very tough milestones. We expect to see the same kind of progress during our next challenge of ramping up the plant to nameplate capacity and design recovery. Many of the key contractors have been retained for Phase 2 to ensure continuity and to carry over learnings from Phase 1. Phase 2 construction is moving along nicely and is tracking slightly ahead of plan.”
Mr. Friedland added: “We are proud of the entire Kamoa-Kakula team for their remarkable dedication and accomplishments to deliver our Phase 1 production ahead of schedule and on budget, despite the challenges presented by the COVID-19 pandemic. We would especially like to extend our deepest gratitude to the Kamoa-Kakula leadership team. Their unwavering passion, vision and commitment to excellence is critical to the ongoing transformation and growth of our business.
“The start of production at Kakula marks the beginning of a multi-generational copper mining district, consisting of numerous high-grade mines. We now turn our focus to scaling up this expansive copper region in a manner that is ethically- and socially-responsible, and setting a new global benchmark for the elimination of greenhouse gases in the production of copper that the world urgently needs.”
Robert Friedland to participate in a virtual fireside chat at the 2021 Goldman Sachs Copper Day on May 5 at 11:45 AM ET
Mr. Friedland will discuss Kamoa-Kakula’s expansion plans, the company’s Western Foreland exploration plans, his views on the global copper market and copper’s role in the green energy transition. He also will provide his thoughts on the inevitable differential pricing for all commodities based on their ESG production characteristics as blockchain technology is integrated and smarter markets are established. The Goldman Sachs Copper Day conference is by invitation only for institutional clients.
“Given that Goldman Sachs’ metals strategists recently called copper the “new oil” and predicted copper prices could reach US$15,000 a tonne by 2025, I expect it to be a lively discussion,” said Mr. Friedland.

Kakula is projected to be the world’s highest-grade major copper mine, with an initial mining rate of 3.8 Mtpa at an estimated early average feed grade of more than 6.0% copper, ramping up to 7.6 Mtpa in Q3 2022.
Phase 1 is expected to produce approximately 200,000 tonnes of copper per year, and Phases 1 and 2 combined are forecast to produce approximately 400,000 tonnes of copper per year. 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.
Given the current copper price environment, Ivanhoe and its partner Zijin are exploring the acceleration of the Kamoa-Kakula Phase 3 concentrator expansion from 7.6 Mtpa to 11.4 Mtpa, which may be fed from expanded mining operations at Kansoko, or new mining areas at Kamoa North (including the Bonanza Zone) and Kakula West.
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.
Kamoa-Kakula is connected to one of the world’s greenest power grids, including power supplied from the newly upgraded Mwadingusha hydropower plant.

The main mine 220-kilovolt (kV) Kamoa Consumer Substation (KCS) has been energized on grid power, as has the 33kV KCS substation. The main plant 33kV substation and all the plant medium-voltage and low-voltage substations also have been energized, and the plant now is electrically live.
Construction complete (C1) sign off is nearing completion with approximately 75% of the certificates signed off and handed over from construction to commissioning. C2 (pre commissioning) commissioning is well underway with some areas (crushing and screening, milling) more than 90% complete. Early C3 activities (checking for leaks, certain instrument calibration, control-loop checks) have started with water being circulated around certain areas in the plant.
Electrical installation at the backfill plant is ongoing and the backfill plant is scheduled to be completed in July, well before paste backfill is required for mining operations.
The backfill plant will be used to mix tailings from the processing plant with cement to produce paste backfill. The backfill will be pumped back into the mine and used to help support mined-out areas. Approximately one half of the mine’s tailings will be sent back underground, significantly reducing the surface tailings storage. Construction of the tailings storage facility is progressing well and is scheduled to be completed on time to receive tailings from the processing plant.

In December 2020, the 35-kilometre-long double circuit 220-kilovolt (kV) power line to Kamoa-Kakula was connected to the national electrical grid through theNew Western Dispatch substation in Kolwezi. Kamoa-Kakula’s main 220-kV substation was energized with 220-kV power from the national power grid on March 25 and the first of two 33-kV transformers on March 29.
Three of the six new turbines at the Mwadingusha hydropower plant now have been synchronized to the national electrical grid, with each generating unit producing approximately 13 megawatts of power. The completion and commissioning of the hydropower plant’s remaining generating units, in sequence, is in progress.
In April, Kamoa-Kakula’s energy company signed an agreement with the DRC’s state-owned power company to upgrade Turbine 5 at the Inga II hydropower complex. Turbine 5 is expected to produce 162 megawatts of renewable hydropower, providing the Kamoa-Kakula Copper Complex and associated smelter with abundant, sustainable electricity for future expansions.
The Mwadingusha hydropower plant soon is expected to deliver 78 megawatts of clean power to the national electrical grid.
Turbine 5 (penstock circled in red) at the Inga II hydropower complex is expected to generate an additional 162 megawatts of clean power after upgrading.
COVID-19 prevention and treatment initiatives successfully maintained, with focus on personnel staying vigilant about COVID safety protocols
Kamoa-Kakula has successfully focused on prevention, preparation and mitigation in managing the risks associated with COVID-19. Large-scale testing, combined with focused preventative measures, ensured that positive cases were quickly identified, isolated and treated, with cross contamination kept to a minimum. Maintaining this high standard of risk management remains a daily focus, to prevent future cases.
The Kamoa COVID-19 hospital continues to treat patients when required, as construction progresses for the expansion and upgrade of the primary healthcare wing of the hospital. Kamoa-Kakula’s highly experienced doctors and nurses apply the latest medical treatments, supported by a world-leading emergency response and paramedic team.

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) 今天欣然宣布，卡莫阿-卡库拉 (Kamoa-Kakula) 第一序列选厂的建设和试车正在快速推进且进展顺利，第四阶段试车 (C4) (选矿和首批铜精矿生产) 的目标日期将提前至5月底或6月初，比原计划提前数月。
项目第一序列380万吨/年选厂的整体施工将近完成，第一阶段 (建设完成) 的C1证书大多数已获签字。选厂已获得长期电力供应，并正进行第二阶段试车 (C2) 且进度顺利，涉及电器、控制和仪表的检查。目前已开展第三阶段 (C3) 试车，在部分厂区加水运行，检查有否泄漏、校准部分仪器及检查控制环，并为第四阶段试车 (加料试车) 作好准备，选厂开始生产铜精矿。
4月份采出的40.9万吨矿石中，包括在卡库拉矿山采出的35.7万吨矿石，铜品位5.70% (其中包含在矿床高品位中心采出的12.1万吨矿石，铜品位高达8.40%) ，以及在卡索科 (Kansoko) 矿山采出的51,000吨矿石，铜品位5.85%。
卡库拉矿区的进路充填采矿作业进展顺利，开采的矿石大部分来自回采作业，其余来自掘进。进路充填是一种高效的地下采矿方法，完成一条单一的巷道 (称为采场) 的采矿后，进行采空区回填，进而可以依次开采相邻的采场。回填厂将尾矿与水泥混合制造回填膏体，并将于7月开始将回填料泵回井下作业。
卡莫阿铜业首席执行官马克·法伦 (Mark Farren) 说﹕“采掘班组于4月份的表现保持理想，持续超计划推进采掘工作，投产前堆矿量现已达到300万吨的目标。月度采矿速率已超越第一序列的选矿速率，预计堆矿量将会继续增加，并且仅在第二序列选厂于2022年中投产时才会逐渐减少。”
弗里兰德先生将讨论卡莫阿-卡库拉的扩建方案、公司西部前沿 (Western Foreland) 项目的勘探方案，并对于全球铜市场以及铜金属在绿色能源转型中扮演的角色发表意见。随着区块链技术的整合和更高效的市场发展，大宗商品的定价因ESG (环境、社会和公司管冶) 的生产特性而出现差异，弗里兰德先生将分享他在这方面的想法。高盛铜业日大会仅限受邀的机构客户参加。

本新闻稿中关于矿堆的其它科学或技术性披露已经由乔治·吉尔克里斯特 (George Gilchrist) 审查和批准，他凭借其教育、经验和专业协会会籍被认为是NI 43-101 条款下的合资格人。由于吉尔克里斯特先生是艾芬豪矿业资源部副总裁，因此他并不符合NI 43-101 对独立人士的界定。吉尔克里斯特先生已核实本新闻稿所披露的其它技术数据。
本新闻稿所载的矿堆品位估算值是基于早前从地下巷道的大样以及从最近开展的垂直剖面刻槽取样。每个巷道进行第二次爆破时取样，并采集3个5公斤重的样品。从2020年10月起使用刻槽取样的样品作为矿堆品位估算的主要数据，大约每15米在整个垂直剖面上使用手持式切割机按1米垂直间隔进行采样，收集100-150克重的样品。在项目现场实验室磨样加工后，使用便携式XRF (pXRF) 仪器进行分析。除了在商业实验室利用4酸消解和ICP-OES进行分析之外，卡莫阿铜业也经常使用pXRF分析钻孔岩芯中的铜含量。该数据表明，pXRF结果可用于品位控制和原矿取样。由于四舍五入，本新闻稿所载数字的相加可能与总和不符。
