KOLWEZI, DEMOCRATIC REPUBLIC OF CONGO – Ivanhoe Mines (TSX: IVN; OTCQX: IVPAF) Co-Chairs Robert Friedland and Yufeng “Miles” Sun are pleased to announce that underground development at the Kamoa-Kakula Copper Project in the Democratic Republic of Congo (DRC) produced a combined 250,000 tonnes of ore grading 4.85% copper in November from the Kakula and Kansoko mines. The tonnage was 29% higher than achieved in October, while the monthly copper grade increased from 4.01% to 4.85%.
The project’s pre-production surface stockpiles now contain approximately 1.25 million tonnes of high-grade and medium-grade ore at an estimated grade of 3.75% copper. Contained copper in the stockpiles increased by approximately 12,100 tonnes in November – a 55% increase over October’s production – to a cumulative total of more than 46,700 tonnes (the current copper price is approximately US$7,670 a tonne). The project is on track to have approximately three million tonnes of high-grade and medium-grade ore stockpiled on surface, containing more than 125,000 tonnes of copper, prior to the planned start of production in July 2021.
Mr. Friedland and Mr. Sun also noted that underground mine development totalled 2,163 metres in November – only 10 metres shy of establishing another new monthly record. A key milestone was achieved in early November with the joining of Kakula’s main northern and southern access tunnels, establishing access to begin mining Kakula’s high-grade ore in the centre of the orebody grading approximately +8% copper (see figures 1, 2 and 3). The holing event was advanced only from one end for the last few days as a standard safety precaution, which had a minor effect on the metres achieved.
The holing has allowed Kakula’s mining crews to enlarge the development drifts in the centre of the deposit to 7-metres wide by 7-metres high (approximately 23-feet wide by 23-feet high) to take advantage of the excellent copper grades across a thick ore zone – providing a substantial increase in tonnes per metre of development.
November’s development brings total underground development to more than 26.8 kilometres – approximately 9.0 kilometres ahead of schedule. The monthly total of 2,163 metres of underground development in November was comprised of 1,840 metres at the Kakula Mine and 323 metres at the Kansoko Mine, which is located at the Kamoa Deposit – approximately 10 kilometres north of the Kakula Mine.
Mark Farren, Kamoa Copper’s CEO, commented: “November was a great month for mine development. Not only did we join the Kakula’s main access tunnels that now provides a transportation and ventilation connection between the northern and southern declines – a distance of approximately four kilometres, we also achieved record ore production at significantly better copper grades. We expect this production trend to continue as additional mining crews begin working in the centre of the high-grade Kakula orebody. We also saw a sharp increase in copper grades at the Kansoko Mine in November, resulting from ongoing exposure of a rapidly thickening layer of copper-rich siltstone.”
“This month we expect to achieve three key construction milestones – energizing the newly installed 220-kilovolt power line feeding Kamoa-Kakula with hydro-generated electricity from the national grid; synchronization of the first of six turbines at the refurbished Mwadingusha hydropower plant onto the national grid; and commissioning the main surface rock-handling, by-pass conveyor system that will enable the delivery of ore from the Kakula Mine directly to the concentrator plant stockpiles,” Mr. Farren added.
Underground mining crews at Kakula are focused on developing the high grade, drift-and-fill mining blocks in the centre of the orebody. Opening up of the mining footprint for these high grade, drift-and-fill mining areas entails, by necessity, development work in areas of low-, medium- and high-grade ore, and is designed to coincide with the start-up of the processing plant next year. This will allow crews to deliver significant tonnage of high-grade ore directly from Kakula’s underground workings to the processing plant.
While most of the underground development at the Kansoko Mine is in medium-grade ore, in late November mining crews entered the deposit’s initial high-grade ore zone, with 2,100 tonnes of high-grade ore grading 6.66% copper mined by month’s end. Kansoko’s combined medium-grade and high-grade ore mined in November was approximately 33,000 tonnes at an average grade of 3.87% copper. Ongoing exposure of a rapidly thickening siltstone is the reason for a sharp increase in copper grades at Kansoko in November. Siltstone is a rock type with a strong influence on copper mineralization at Kamoa-Kakula.
Kansoko is being developed by training crews and will be a supplemental source of ore for Phase 2 of the project’s development when the Kakula concentrator processing capacity doubles to 7.6 million tonnes per annum (Mtpa) − currently planned to be commissioned in Q3 2022.
Phase 1 copper production from the Kakula Mine is scheduled to begin in July 2021. 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 average feed grade of more than 6.0% copper over the first five years of operation. 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.
An 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.

November’s ore production 29% higher than October, with monthly copper grade increasing from 4.01% to 4.85%; pre-production surface ore stockpiles now total approximately 1.25 million tonnes grading 3.75% copper
In November, mining crews at the Kakula and Kansoko mines mined and transported to surface approximately 250,000 tonnes of ore grading 4.85% copper. This brings the project’s total pre-production high- and medium-grade ore stockpiles to approximately 1.25 million tonnes at an estimated grade of 3.75% copper. An additional 622,000 tonnes of low-grade development ore also has been stockpiled on surface.
November’s ore production is approximately 29% higher than the 194,000 tonnes grading 3.47% copper mined in October, and approximately 89% higher than the 132,000 tonnes grading 3.31% mined in September. The project is well positioned for continued acceleration in the tonnage, as well as an increase in the grade, of ore added to the surface stockpiles as more mining crews commence mining in the higher-grade areas of the Kakula and Kansoko mines.

Construction of the initial 3.8-Mtpa concentrator plant and other surface infrastructure rapidly progressing; earthworks and civil works started, and EPCM contract awarded for the second 3.8-Mtpa concentrator plant
Overall progress of Kamoa-Kakula’s first-phase, 3.8 Mtpa mining and milling operation (covering mine infrastructure, concentrator plant and surface infrastructure) now is approximately 63% complete, up from 58% last month. Overall construction of the project’s first-phase 3.8 Mtpa concentrator plant and associated facilities is advancing rapidly and is approximately 35% complete, up from 28% last month. The concentrator plant is expected to be mechanically complete in Q2 2021, with first copper concentrate production scheduled for July 2021.
Civil works for the initial concentrator plant are more than 90% complete, with approximately 28,000 cubic metres of concrete poured to date. All major construction areas have handed over to the steel, mechanical, piping and platework (SMPP) contractor.
More than 2,000 truckloads of equipment have been delivered to site, including the final major pieces of equipment − two 80-MVA/220-kilovolt (kV) electrical transformers. The transformers have been placed into position at the main Kakula substation and construction of the project’s various electrical substations is progressing well.
All structural steel has been delivered to site, as well as the bulk of the platework and piping. Piping installation has started, as has electrical installation of cable racks and cable installation.
Over 3,000 tonnes of steel (of a total of 5,700 tonnes) has been installed. SMPP erection and installation has commenced in all areas of the concentrator plant and is well advanced. Electrical installation is underway in the milling, flotation and thickener areas.
A recent focus area was to install roof sheeting on the reagent storage building and the concentrate storage building to allow on-site fabrication work to continue during periods of rain.
Steel erection for Kakula’s first phase, backfill paste plant is well advanced with the bulk of the outer structure complete including the installation of the gantry crane, the installation of the two 2000t cement silos is underway. Structural steel erection is scheduled to be completed in early 2021.
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 dam is progressing well and is scheduled to be completed well ahead of the required date. Installation of the three tailings lines and the tailings return water line is nearing completion.
The long-lead items for the second 3.8-Mtpa concentrator plant have been ordered and the Phase 2 of the project’s development is underway. Contracts have placed for the earthworks, and civil works and bush clearing has started. The Engineering, Procurement and Construction Management (EPCM) contract also has been signed with ENFI Engineering Corporation, of Beijing, China.

Advanced, detailed discussions underway for the marketing of Kakula’s copper concentrates
Kamoa-Kakula is in advanced, detailed discussions with a number of parties with respect to the sale of its copper concentrates. Kakula is expected to produce an extremely high grade and clean copper concentrate (containing over 55% copper) that will be highly coveted by copper smelters around the world. Metallurgical test work indicates that the Kakula concentrates contain extremely low arsenic levels by world standards – approximately 0.01%.

Kamoa-Kakula’s COVID-19 prevention initiatives focused on risk mitigation
Kamoa-Kakula’s prevention measures remain strictly enforced. Rigorous testing, physical distancing, wearing face masks, frequent hand washing and contact-tracing measures are still in place to protect the safety and health of the workforce and community members.
The project has established a COVID-19 isolation facility at the Kamoa camp. Potential symptomatic patients are moved to this facility, where they will be isolated, tested and treated. Once patients have recovered and are deemed no longer infectious, they can return to work only after an additional quarantine period determined by the project’s medical staff.
As the pandemic evolves, the medical team at Kamoa-Kakula continues to review and update its risk mitigation protocols. The project’s preventative measures are at the highest international standards and should there be a case internally, the risk of spreading or cross-contamination is considered to be very low.
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 DRC government (20%).

The stockpile grade estimates contained in this release are based upon bulk ore sampling from earlier underground headings, and vertical channel sample profiles from recent development. Bulk ore sampling was done on each heading every second blast and three 5-kilogram samples were taken. Since the beginning of October 2020, channel sample profiles are the primary data informing the stockpile grade estimates. These are cut approximately 15 metres apart in 1-metre vertical increments across the full vertical exposure using a handheld grinder, with a 100-to-150-gram sample collected. The samples are pulverized at the project’s onsite laboratory and analyzed using a portable XRF (pXRF) instrument. Kamoa Copper has routinely analyzed its exploration drill core for copper using pXRF, in addition to analysis at a commercial laboratory using four acid digest and ICP-OES. This data has demonstrated that pXRF results can be relied upon for grade control and run-of-mine sampling.

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，其位于刚果民主共和国 (以下简称“刚果(金)”) 的卡莫阿-卡库拉铜矿项目的地下开发持续推进，11月份在卡库拉和卡索科矿山共采掘了250,000吨矿石，铜品位4.85%，矿石量相比10月份高出29%，月度铜品位从4.01%提升至4.85%。
项目的投产前地表堆场，目前已储备了约125万吨高品位和中品位矿石，铜品位约3.75%。矿堆的含铜量于11月份提升至约12,100吨 — 相比10月份高出55%，累计含铜量达46,700吨以上 (目前的铜价约每吨铜7,460美元)。项目将按计划于2021年7月实现投产前，在地表堆场储备约300万吨高品位和中品位矿石，含有超过125,000吨铜金属。
弗里兰德先生和孙先生表示，采掘班组于11月份共掘进2,163米，与项目的月度最高记录仅仅相差10米。卡库拉南北两条主要运输通道已于11月初完成贯通，实现了项目的一个重要里程碑，并到达高品位的矿床中心，该矿段的铜品位约8%以上 (见图1、2和3 )。根据标准的安全预防措施，贯通工程在过去几天只是从一端推进，但对整体的掘进距离影响不大。
卡莫阿铜业首席执行官马克·法伦(Mark Farren) 说﹕“11月份的矿山开发进展理想。卡库拉主要运输通道已完成连接，为南北两面的斜坡道(相距约4公里)提供运输通道并改善通风情况。此外，我们还创下了采掘矿石量的纪录，且铜品位显著增加。随着更多采掘班组在卡库拉矿床中心的高品位矿段开始作业，我们预计这个增长势头将会持续下去。11月份，卡索科矿山录得的铜品位急剧上升，主要是由于接触到的富铜粉砂岩层不断加厚。”
法伦先生补充说﹕“我们预计将于本月实现三项关键的建设里程碑，包括﹕新安装的220千伏电力线将会通电，从国家电网为卡莫阿-卡库拉项目提供水电能源；翻新后的 Mwadingusha 水电厂6台涡轮机中的第1台将与国家电网同步；以及主要的地表岩石分支输送系统将开始运行，直接从卡库拉矿山运送矿石至选矿厂的堆场。”
从左至右﹕生产经理 Magloire Kashiba、业务主管 Jan Strydom、艾芬豪矿业总裁兼首席财务官玛娜·科洛特 (Marna Cloete) 和部门经理 Pontien Kalala 共同庆祝卡库拉的主要通道于11月初完成贯通，为南北两面的斜坡道提供运输通道并改善通风情况。
11月份开采的矿石量较10月份 (194,000吨，铜品位3.47%) 高出约29%，较9月份 (132,000吨，铜品位3.31%) 则高出约89%。随着更多采掘班组在卡库拉和卡索科矿山的高品位矿段开始作业，项目将继续大大提升地表堆场的矿石量，且矿石品位将会有所增加。
此外，项目还有两个额外的投产前矿堆，分别位于卡库拉南面斜坡道 (约107,000 吨高品位矿石，铜品位6.11%以及224,000吨中品位矿石，铜品位2.64%) 和卡索科斜坡道 (约2,100 吨高品位矿石，铜品位6.66%以及151,000吨中品位矿石，铜品位2.82%)。
卡莫阿-卡库拉第一序列的年处理矿量380万吨开采选矿作业 (包括矿山基础设施、选矿厂和地表基础设施) 整体施工进度理想，目前已完成约63%，上月则完成了58%。项目第一座380万吨/年选矿厂和相关基础设施的整体施工正在快速推进，目前已完成约35%，上月则完成了28%。选矿厂预计于2021年第二季度完工，并计划于2021年7月实现首批铜精矿生产。
超过2,000辆卡车的设备 (包括最后的主要设备 — 两台80兆伏安/220千伏的变压器) 已抵达矿场。变压器已放到卡库拉变电站内的指定位置，项目多个变电站的施工进度理想。
目前，超过3,000吨 (总共5,700吨) 的钢结构已完成安装。选矿厂所有厂房区域已经开始进行SMPP的搭建和安装且进展顺利。选矿、浮选和浓密区的电器安装也正在进行中。

卡莫阿-卡库拉预计将于本月晚些时候，与位于科卢韦齐的西部调度 (Western Dispatch) 变电站通过一条35公里长的220千伏电力线相连通，从国家电网为项目提供可靠和清洁的水电能源。
艾芬豪矿业刚果(金)能源公司 (Ivanhoe Mines Energy DRC) 公布，Mwadingusha水电站3台涡轮机的第一台已于11月26日进行最终调试，并将于今年内全面组装。这台涡轮机将于12月10日与国家电网同步，为水电厂余下5台发电机日后的调试做准备，确保卡莫阿-卡库拉在选矿厂投产前获得充足的电能供应。全面翻新后的水电厂预计将向国家电网提供72 兆瓦的电力。
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(金)政府 (占股20%) 的合资项目。

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块矿石取样以及从最近开发的垂直剖面刻槽取样。每个巷道进行第二次爆破时取样，并收集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研磨机按1米垂直增量进行采样，收集100-150克重的样品。样品在项目现场实验室粉碎后，使用便携式XRF (pXRF) 仪器进行分析。除了在商业实验室利用4种酸分解液和ICP-OES进行分析之外，卡莫阿铜业也经常使用pXRF分析其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采矿井取样。
