KOLWEZI, DEMOCRATIC REPUBLIC OF CONGO – Ivanhoe Mines (TSX: IVN; OTCQX: IVPAF) Co-Chairs Robert Friedland and Yufeng “Miles” Sun announced that ramp-up of Kamoa-Kakula’s Phase 1, 3.8 million-tonne-per-annum (Mtpa) concentrator plant continues to advance ahead of schedule, with 319,795 tonnes of ore milled in September, exceeding the monthly design run rate of 316,667 tonnes at an average feed grade of 6.0% copper.
A total of 16,010 tonnes of copper in concentrate were produced (filtered product) and a total of 16,503 tonnes floated in the reporting month ended September 20th – Kamoa Copper’s fourth full month of production – establishing a new monthly record and nearing the Phase 1 target output of 16,666 tonnes per month, or 200,000 tonnes per annum. The difference between filtered and floated copper is approximately 500 tonnes in inventory in the concentrate thickener and the filter feed tank.
The average floated concentrate copper grade in September improved to 55.7%, up from approximately 48% in August. A total of 46,764 tonnes of copper in concentrate had been produced year-to-date as of September 20, 2021, for delivery to either the Lualaba Copper Smelter near Kolwezi, or to international markets.
Copper flotation recoveries improved to an average of 85.1% during September, up from an average of 83% during August. The Phase 1, steady-state-design copper recovery is approximately 86%, depending on ore feed grade.
A daily record copper recovery of 88.3% was achieved on September 12th and a daily floated copper production of 721 tonnes was achieved on September 15th. Subsequent to the reporting period, a daily milling record of 12,596 tonnes and a daily crushing record of 14,778 tonnes were achieved on September 27th.
Chart 1: Cumulative tonnes of copper produced May 2021 to September 20, 2021.The August total has been adjusted to reflect cumulative copper produced to August 20, 2021 (the new monthly reporting cut-off date).
Mark Farren, Kamoa Copper’s CEO, commented on September’s operating performance: “The Kamoa-Kakula team has worked tirelessly to bring the Phase 1 concentrator to steady-state performance. We are very pleased with the September results, where we exceeded steady-state design parameters for ore throughput and were close to achieving steady-state design copper recovery and monthly copper production.
“There are a number of additional adjustments being incorporated into the Phase 1 processing circuit, which will enable the concentrator to achieve better results in the next quarter. These adjustments, which also will be incorporated into the Phase 2 processing circuit, should position us to achieve 2021 copper production in the upper end of our previous guidance of 80,000 to 95,000 tonnes. This gives us the confidence to raise the range to 85,000 to 95,000 tonnes.
“Mining production was steady at 384,000 tonnes produced from the Kakula and Kansoko mines. The mining teams now are well established and are able to consistently outperform our internal budget. We have established a solid base of skilled and motivated Congolese workers, who no doubt will carry us through the ramp-up of Phase 2 and subsequent expansions of our mining footprint. It also is encouraging to note that the Phase 2 concentrator construction remains solidly ahead of schedule and on budget.”
Ivanhoe’s production guidance for contained copper in concentrate at Kamoa-Kakula in 2021 has been raised to 85,000 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 guidance assumes ramp-up continues in line with published technical disclosures.
Performance guarantee tests were successfully completed on the Phase 1 concentrator plant during the first three days of September. The performance tests involved a 72-hour continuous run at steady-state design, or above, ore throughput and grind.
Kamoa-Kakula is fast tracking the commissioning of an additional concentrate filter, which has been installed alongside the Phase 1 filter, to be able to take advantage of copper feed grades and milling rates in excess of design parameters. The additional concentrate filter is expected to be fully operational in early October 2021, enabling the Phase 1 concentrator to produce more copper than its design capacity of approximately 200,000 tonnes per year.

Phase 2 concentrator plant overall construction more than 50% complete, with the current focus on structural steel, mechanical, piping and platework (SMPP) erection and installation
Construction of the second 3.8-Mtpa concentrator plant (Phase 2) is progressing well, with the overall project more than 50% complete; engineering and procurement activities are effectively complete with fabrication at 86% complete. Civil construction works also are effectively complete, with the focus now on erection of structural steel and the installation of platework and equipment. A 400-tonne crane (the largest in the DRC) has arrived on site and has been used to lift the tailings thickener rake into position. The crane also will shortly be used to install the ball mills, the ball mill shells, girth gear and ball mill ends, all of which are on site.
The bulk of the 2,193 tonnes of structural steel and the 570 tonnes of platework is on site and the bulk of the 18,644 metres of piping is en route to site. The six-kilometre tailings return water piping has been delivered to site and installation is nearing completion. More than 418 truckloads of Phase 2 construction equipment and materials already have been delivered to site and another 49 truckloads are en-route. The Phase 2 concentrator remains on track for completion in Q3 2022.
Commissioning of the Phase 1 backfill is advancing well with C4 (hot commissioning) activities. More than 7,250 cubic metres of paste backfill have been pumped to an underground trial stope in the Kakula Mine.

Mining continues ahead of schedule, adding to the surface ore stockpiles
A total of 384,000 tonnes grading 5.58% copper was mined during the period from August 21 to September 20, including 141,000 tonnes grading 7.32% copper from the Kakula Mine’s high-grade centre and 36,000 tonnes grading 4.89% copper from the Kansoko Mine.
The project’s surface stockpiles now contain approximately 3.66 million tonnes of high-grade and medium-grade ore at an estimated, blended average of 4.73% copper. Contained copper in the stockpiles at the end of August now totals more than 173,000 tonnes (the current copper price is approximately US$9,200 per tonne).
In September, crews began 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.
The Kakula Mine, concentrator plants and main ore stockpiles at Kakula’s northern declines (in red circle). The blended stockpiles currently contain approximately 1.80 million tonnes grading 5.04% copper.
The Kakula southern decline and ore stockpiles containing a combined 1.33 million tonnes grading 4.65% copper (consisting of 602,000 high-grade tonnes @ 6.19% copper and 732,000 medium-grade tonnes @ 3.39% copper).
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. The project is on track to complete the Phase 2 expansion in Q3 2022. 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.
Study work advancing to accelerate Phase 3 mine and concentrator expansion
Study work for the Phase 3 mine and concentrator expansion is underway, which includes optimization work to determine mining production capacity and costs at the various mining areas on the Kamoa-Kakula complex, including expanded facilities at the Kansoko Mine, Kamoa North (including the Bonanza Zone) and Kakula West.
This work also will determine the optimal sizing of the Phase 3 concentrator, which was outlined as a further expansion of 3.8 Mtpa in the Kamoa-Kakula Integrated Development Plan announced in September 2020. In addition, the studies will take into consideration the expected timeline for the upgrade of turbine 5 at the Inga II hydropower complex to provide 162 megawatts of renewable hydropower, as well as the construction of a direct-to-blister smelter.
Once the optimization work is completed, Kamoa Copper will advance into a more detailed phase of design and engineering work with its objective to accelerate the Phase 3 concentrator expansion.

In early 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, 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.
Early works related to the removal of sand from area around turbine 5 is in progress, which will allow the engineering team to complete the scoping work. Ivanhoe expects to soon be in a position to provide an update on the expected upgrading costs for turbine 5 as well as the expected timeline for completion of the upgrading project.
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.

本新闻稿中关于卡莫阿-卡库拉项目开发方案的科学或技术性披露已经由史蒂夫·阿莫斯 (Steve Amos) 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 标准下的合资格人。由于阿莫斯先生是卡莫阿铜业的项目负责人，因此他并不符合NI 43-101 对独立人士的界定。阿莫斯先生已核实本新闻稿所披露的技术数据。
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。
