KOLWEZI, DEMOCRATIC REPUBLIC OF CONGO – Ivanhoe Mines (TSX: IVN; OTCQX: IVPAF) Co-Chairs Robert Friedland and Yufeng “Miles” Sun announced that Kamoa-Kakula’s Phase 1, 3.8 million-tonne-per-annum (Mtpa) concentrator plant has met, or exceeded, all design criteria and now is operating at steady-state. Optimization work is underway to further enhance the plant’s operating performance.
A total of 323,368 tonnes of ore was milled in October at an average feed grade of 5.89% copper, exceeding the monthly design run rate of 316,667 tonnes.
Production during the last 10 days of October averaged 611 tonnes of copper in concentrate per day. On October 25, a new daily production record of 729 tonnes of copper in concentrate was achieved.
A record 16,211 tonnes of copper in concentrate was produced (filtered product) in the reporting month ended October 20 – Kamoa Copper’s fifth full month of production –nearing the Phase 1 target output of 16,666 tonnes per month, or 200,000 tonnes per annum.
The average floated concentrate copper grade in October was 51.5%. A total of 62,974 tonnes of copper in concentrate had been produced year-to-date as of October 20, 2021, for delivery to either the Lualaba Copper Smelter near Kolwezi, or to international markets.
Copper flotation recoveries averaged 85.1% in October. The Phase 1, steady-state-design copper recovery is approximately 86%, depending on ore feed grade.
As the Phase 1 concentrator plant is operating at steady-state design capacity, further production updates will be provided only on a quarterly basis, but reporting on Phase 2 construction progress will continue. Ivanhoe Mines will report its Q3 2021 financial results before market open on Monday, November 15, 2021, which will include the inaugural quarterly financial results for Kamoa-Kakula.

Mark Farren, Kamoa Copper’s CEO, commented: “October was an important milestone month for us in many ways. The project team managed to commission the second concentrate filter press which we believe will create a lot of flexibility downstream. Concentrate volumes now can be increased to match the potential of the front end of the concentrator plant (milling), enabling recoveries to be tweaked by increasing the mass pull to the concentrate thickener. While it took a few weeks to fine tune the second filter press, the plant performance met steady-state expectations despite intermittent regional power outages during the first three weeks of October. The last 10 days of the month saw production average 611 tonnes of copper in concentrate, and a new daily production record of 729 tonnes of copper was achieved on October 25. This excellent achievement highlights the level of production we are targeting in future.
“Barring any major issues, the operational team is confident that we will reach the upper end of our production guidance of between 90,000 and 95,000 tonnes of copper in concentrate in 2021.
“Also during October, the Kakula mining team encountered a significant inflow of water at the northern perimeter drift. This water inflow was well managed and monthly underground production volumes were maintained at approximately 400,000 tonnes. Surface ore stockpiles have increased to more than 3.73 million tonnes. This trend is likely to continue into Q2 2022, when the Phase 2 concentrator is expected to begin operations. The Phase 2 concentrator construction remains ahead of schedule and on budget.”
Ivanhoe’s production guidance for contained copper in concentrate at Kamoa-Kakula in 2021 has been increased to 90,000 to 95,000 tonnes. 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 second concentrate filter press was commissioned during the month and now is fully operational. The second filter removes a bottleneck to allow Kamoa-Kakula’s Phase 1 concentrator to take advantage of the exceptionally high-grade copper ore being processed directly from Kakula’s underground mining operations and surface stockpiles, and produce copper concentrate above design parameters.
As a result of instability of the regional transmission network, intermittent power outages were observed during the first three weeks of October. This had a negative impact on October’s copper production and overall mine and mill performance. Kamoa Copper, together with the DRC state-owned company La Société Nationale d'Electricité (SNEL), have identified three critical areas in the regional transmission network that require urgent upgrading to significantly improve network reliability, which are expected to be completed in the next two months at an estimated capital cost of under US$0.5 million. In addition, Kamoa Copper is evaluating longer-term options for back-up power storage to maintain full operations during interruptions.

Phase 2 concentrator plant construction is approximately 60% complete, with current focus on structural steel, mechanical, piping and platework (SMPP); electrical installation now underway
On October 22, 2021, the project construction team reached 4.0 million lost-time-injury-free hours. This milestone underscores the strict safety culture of the Kamoa Copper construction team and contractors.
Construction of the second 3.8-Mtpa concentrator plant (Phase 2) is progressing well, with the overall project approximately 60% complete; engineering and procurement activities are effectively complete, with fabrication over 92% complete. The main construction focus remains on the erection of structural steel and the installation of platework and equipment. Both ball mills have been lifted into position and installation of the girth gears currently is underway. The mill installation is expected to be complete by the end of the year. All 14 flotation cells (eight rougher/scavengers and six cleaners) are in position. Electrical cable installation has commenced.
The bulk of the 2,193 tonnes of structural steel and 570 tonnes of platework is on site and the majority of the 18,644 metres of piping is en route to site. The last deliveries of structural steel, piping and platework are expected to arrive by the end of November. More than 550 truckloads of Phase 2 construction equipment and materials already have been delivered to site and another 31 truckloads are en route.

Mining continues ahead of schedule, adding to the surface ore stockpiles <
A total of 395,000 tonnes grading 5.73% copper was mined during the period from September 21 to October 20, including 174,000 tonnes grading 6.91% copper from the Kakula Mine’s high-grade centre and 35,000 tonnes grading 3.84% copper from the Kansoko Mine. The project’s surface stockpiles now contain approximately 3.73 million tonnes of high-grade and medium-grade ore at an estimated, blended average of 4.72% copper. Contained copper in the stockpiles at the end of August now totals more than 175,000 tonnes (the current copper price is approximately US$9,500 per tonne).
Since September, crews have been transporting high-grade ore from the surface stockpile near the Kakula southern decline directly to the Phase 1 concentrator plant or to the main surface stockpiles near the Kakula northern decline.
During October, a north-south, water-bearing structure was intersected at the Kakula Mine’s northern perimeter drift. This new structure produced a considerable water in-flow that caused some localized flooding in the surrounding workings in early October. The water inflow has been controlled and the flooded areas have been largely dewatered.The inflow caused the mine’s average dewatering rate to increase to a peak of approximately 1,300 litres per second (l/s).
The Kakula Mine has an installed water-pumping capacity to surface of 2,600 l/s, with plans to increase the mine’s installed pumping capacity to 5,700 l/s in 2022. Hydrological studies are ongoing, with models being updated to reflect the new findings and day-to-day hydrology monitoring, which will be used to plan in advance of mining operations.

The Kansoko decline and ore stockpiles containing a combined 556,000 tonnes grading 3.87% copper (consisting of 176,000 high-grade tonnes @ 5.78% copper and 380,000 medium-grade tonnes @ 2.99% copper).
Figure 1: Underground development completed at Kakula Mine to October 28, 2021 (in black).
Kamoa-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 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 approximately 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.
Initial scope of Phase 3 expansion project nearing completion, with study work advancing; geotechnical drilling work underway to determine exact location of a new box cut to open up Kansoko Central and Kamoa North mining footprint
The scope of Kamoa-Kakula’s Phase 3 expansion includes a third concentrator plant to be located adjacent to the Kansoko Mine (at the Kansoko Sud orebody), approximately 10 kilometres north of the Kakula Mine. The Phase 3 concentrator is being designed to have a larger nameplate milling capacity than the 3.8-Mtpa nameplate milling capacity of the Phase 1 and 2 concentrators.
The planned Phase 3 concentrator is expected to be fed from a combination of the established mine at Kansoko Sud together with opening the Kansoko Central orebody and the first of the Kamoa North mining areas.
Phase 3 also includes the upgrade of turbine 5 at the Inga II hydropower complex to provide an additional 162 megawatts (MW) of renewable hydropower, and the construction of a direct-to-blister smelter, with a production capacity of 500,000 tonnes per annum of blister copper.
Study work on all aspects of the Phase 3 expansion is underway, with expected completion during 2022, after which Kamoa Copper will advance into a more detailed phase of design and engineering work.
In parallel, a location for the new box cut, which will provide access to the Kansoko Central orebody and the first of the Kamoa North mining areas, has been identified and geotechnical drilling is underway to confirm the suitability of the location. Kamoa Copper is expected to break ground on the box cut early in 2022.

Basic engineering design for a Kamoa Copper smelter to be awarded shortly
A feasibility study for an on-site smelter complex at Kamoa-Kakula was completed in early 2021 by China Nerin Engineering Company Ltd. of Jiangxi, China.
Kamoa Copper recently completed a tender process for basic engineering and Engineering, Procurement and Construction Management (EPCM) services for a direct-to-blister smelter with a 500,000-tonne-per-annum production capacity of blister copper. The principal technology for the smelter will be supplied by Outotec Oyj of Helsinki, Finland. All tenders have been received, clarifications carried out and adjudicated. Kamoa Copper expects to award the basic engineering study to the preferred engineering company shortly.
Kamoa Copper’s green energy focus now on the Inga II hydropower plant as source of additional clean electricity to power Kamoa-Kakula expansions
In August 2021, Kamoa-Kakula’s energy company signed an extension of the existing financing agreement with SNEL to upgrade turbine 5 at the Inga II hydropower complex. Since June 2021, rehabilitation scoping works and technical visits have been conducted by Stucky Ltd. of Renens, Switzerland, and Voith Hydro of Heidenheim, Germany, a leading engineering group. Voith Hydro, the contractor for the turbine 5 upgrade, has successfully rehabilitated two turbine generators at the adjoining Inga I hydropower plant, a project that was financed by the World Bank.
Turbine 5 is expected to produce 162 MW of renewable hydropower, providing the Kamoa-Kakula Copper Complex and the planned, associated smelter with abundant, sustainable electricity for future expansions.
Early works related to the removal of sand from the area around turbine 5 is nearing completion, which will allow the engineering team to complete the scoping work. Dismantling of turbine 5, starting on the alternator level, has commenced. Basic engineering for the design of a new turbine wheel and runners is ongoing at Voith’s Heidenheim offices.
Ivanhoe Mines expects to soon provide an update on the expected upgrading costs for turbine 5, as well as the expected timeline for completion of the upgrading project.

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-卡库拉 (Kamoa-Kakula) I期年处理矿石380万吨选厂已达到或超越所有设计标准，现已实现稳产作业。目前正进行优化工作，将进一步提升选厂的作业产能。
截至10月20日止，即卡莫阿铜业的第5个完整报表月度，共生产精矿含铜金属16,211吨，即将达到 I 期目标产量16,666吨铜/月或20万吨铜/年。
由于 I 期选厂已达到设计稳态产能，公司日后将只发布季度的生产更新，但仍会继续报告 II 期的建设进度。艾芬豪矿业将于2021年11月15日周一开市前公布2021年第三季度财务报告，其中将包括卡莫阿-卡库拉项目的首个季度财务业绩。
卡莫阿铜业首席执行官马克·法伦 (Mark Farren) 评论说﹕“10月份对我们来说，在多方面有着重要的里程碑意义。项目团队成功实现第二台精矿压滤机的投产，这将为下游带来更大的灵活性。目前，我们可以增加精矿产量以适配选厂的前端生产潜力，通过提升精矿浓密机的产率以调整回收率。第二台压滤机投产后，我们花了数周时间进行微调。虽然10月份前三周出现了地区性的间歇停电，但是选厂仍能保持稳产作业。本月最后10天生产精矿含铜金属达到平均611吨，并于10月25日创下新纪录，单日生产729吨铜。团队的出色表现，更加加强了我们实现生产指导目标的信心。”
“此外，北部巷道10月份出现了大量涌水的问题。卡库拉采矿团队成功控制涌水量，维持地下产量在约40万吨/月的水平。地表矿石堆场现已储备超过373万吨矿石，预计 II 期选厂于2022年第二季度投产时，堆存矿石量将持续上升趋势。II 期选厂的建设工程进展顺利，在预算之内且建设进度超前。”
第二台精矿压滤机于本月启动投产，现已全负荷运行。第二台压滤机将有助于解决瓶颈问题，使卡莫阿-卡库拉 I 期选厂具有直接处理来自卡库拉地下开采和地表矿堆超高品位矿石的优势，并生产优于设计指标的铜精矿。
II 期380万吨/年选厂施工进展顺利，项目整体已完成约60%；工程设计和采购工作基本上已完工，且设备加工已完成92%以上。目前正重点推进钢结构以及钣金和设备的安装。两台球磨机已吊装就位，现正进行齿轮的安装，预计将于年底之前完成球磨机的安装。14台浮选机组 (8台粗选机/扫选机和6台精选机) 已全部安装完成。电缆的安装工作已经启动。
大部分钢结构 (共2,193吨) 和钣金 (共570吨) 已运达现场，而大部分管道 (共18,644米) 则在运送途中。预计最后一批钢结构、管道和钣金将于11月底运抵现场。超过550辆装载 II 期工程设备和材料的卡车已抵达现场，另外31辆卡车在运送途中。

预计卡莫阿-卡库拉将成为全球品位最高的大型铜矿山，初始年开采矿石380万吨，预计投产后前5年的平均入选品位超过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。根据独立研究机构排名，一旦项目扩大产能至处理1,900万吨/年矿石，卡莫阿-卡库拉将成为全球第二大铜矿山，最高年产80多万吨铜。
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。
卡莫阿-卡库拉 III 期扩建的工程范围包括第三座选厂，将建设在卡索科矿山 (卡索科南部矿体) 附近，距离卡库拉矿山以北约10公里处。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。
预计规划中的 III 期选厂将处理来自卡索科南部开采矿石以及即将开拓的卡索科中部矿体和卡莫阿首个采区提供的矿石。

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关于矿堆的其它技术数据。
本新闻稿所载的矿堆品位估算值是基于从地表矿堆供给选厂物料的大样以及从最近开展的垂直剖面刻槽取样。刻槽取样的样品大约每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。
