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) mined and stockpiled 300,000 tonnes of ore grading 5.45% copper from the Kakula and Kansoko mines in January. The tonnage was 11.5% higher than December, while the copper grade was 1.6% higher.
The 300,000 tonnes mined in January included 231,000 tonnes at an average grade of 6.20% copper, including 82,000 tonnes grading 8.80% copper from the high-grade centre of the Kakula Mine.
The project’s pre-production surface stockpiles now contain approximately 1.82 million tonnes of high-grade and medium-grade ore at an estimated blended grade of 4.23% copper. Contained copper in the stockpiles increased by approximately 16,000 tonnes in January – a 25.9% increase over December’s production reflecting increased mining activity in the ultra-high-grade centre of the Kakula Deposit – to a cumulative total of more than 76,000 tonnes (the current copper price is approximately US$7,940 a tonne).
Kamoa-Kakula is on track to have approximately three million tonnes of high-grade and medium-grade ore stockpiled on surface, holding more than 125,000 tonnes of contained copper, prior to the planned start of processing in July 2021.
“In the mining business, grade is king,” said Mr. Friedland. “And the remarkable grade of the ore coming from Kakula is unprecedented for a major mechanized copper mine of this scale. We are just five months away from scheduled first production, which will mark the next step in the evolution of Ivanhoe Mines into a leading, diversified mining company with a development and exploration portfolio of high-value, critical green metals.”
Mr. Friedland and Mr. Sun also congratulated the project team for establishing yet another new monthly record for underground mine development in January with a total of 2,869 metres of advancement.
“A very strong operational and safety performance by our mining teams in January, and overall a terrific start to 2021,” said Mr. Friedland. “We are immensely proud of the more than 6,000 colleagues on site who are delivering this exceptional project on time and on budget. As we rapidly approach initial production, the project is busy recruiting and training the team that will operate the brand new concentrator plant, creating hundreds of additional permanent, well-paying jobs for local Congolese women and men.”
Underground mine development remains well ahead of schedule, providing the confidence to push forward with Kamoa-Kakula’s Phase 2 construction
January’s record-setting advancement brings total underground development to approximately 32.7 kilometres – around 11.6 kilometres ahead of schedule. The monthly underground development in January was comprised of 2,544 metres at the Kakula Mine and 325 metres at the Kansoko Mine.
Drift-and-fill stoping operations recently commenced at the Kakula Mine, with more than 66% of January’s ore production coming from stoping operations and the remaining coming from mine development activities. Stoping is a highly-productive mining method of extracting underground ore, leaving behind an open space known as a stope.
Mark Farren, Kamoa Copper’s CEO, commented: “The achievement of 300,000 tonnes mined in January is significant as Kamoa-Kakula is fast approaching the mining rate needed to sustain the project’s Phase 1 concentrator plant.”
“It will be important to balance mining volumes and surface stockpiles to meet the requirements of both the Phase 1 and Phase 2 concentrators. We now have nearly two million tonnes of medium- and high-grade ore on surface stockpiles, which should grow to approximately three million tonnes ahead of the scheduled start-up of the concentrator in July, significantly minimizing the ramp-up risk as well as streamlining the commissioning phase,” he continued.
“The large surface ore stockpiles will allow Kamoa-Kakula to maximize throughput once the Phase 1 concentrator is commissioned. Based on our projected mining rates over the next year and a half, we are confident that we also will have more than sufficient stockpiles ahead of the Phase 2 concentrator commissioning,” Mr. Farren added.
Kakula’s combined medium-grade and high-grade ore mined in January was approximately 274,000 tonnes at an average grade of 5.56% copper, including 82,000 tonnes grading 8.80% copper from the +8% copper zone in the centre of the orebody. Mining crews at Kakula are primarily focused on developing the drift-and-fill mining blocks in this high-grade centre. Opening up of the mining footprint for these high grade, drift-and-fill mining areas requires development work in areas of low-, medium- and high-grade ore, and is designed to coincide with the start-up of the processing plant in July. This will allow crews to deliver significant tonnage of high-grade ore directly from Kakula’s underground workings to the processing plant.
Kansoko’s combined medium-grade and high-grade ore mined in January was approximately 26,000 tonnes at an average grade of 4.31% copper. Kansoko’s ore grade increased by 73% in January, compared to December. 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 at first, ramping up to 7.6 Mtpa in Q3 2020. 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.
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.
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%).
January’s ore production was 11.5% higher than December, with monthly copper grade increasing from 5.36% to 5.45%; pre-production surface ore stockpiles now total approximately 1.82 million tonnes grading 4.23% copper

Civil works for the first concentrator plant effectively is complete and the civil contractor now is focusing on the Phase 2 concentrator plant, the high-pressure-grinding-rolls (HPGR) stockpile and milling areas.
Delivery of equipment for the first concentrator plant is nearing completion with more than 2,260 truckloads of equipment – including all structural steel, platework, piping and electrical cable – now on site. The sand filter plant and the last shipments of switchgear are scheduled to arrive in February and March 2021, respectively.
Structural steel erection and platework installation for the first concentrator plant is nearing completion, with only 172 tonnes of structural steel still to be erected (of a total of 4,882 tonnes) and 121 tonnes of platework (of a total of 863 tonnes). Mechanical installation is 68% complete. Piping fabrication and delivery is complete and installation is nearing 50% completion. A total of 83 kilometres of piping will be installed.
All plant areas for the first concentrator have been handed over to the electrical, control and instrumentation (EC&I) contractor for electrical installation. EC&I installation is the last activity before construction completion and subsequent commissioning. Installation of cable racking is complete in most areas and cable installation is well advanced with more than 105,000 metres of copper cable installed out of a total of 207,000 metres (207 kilometres). The installation of instrumentation has started and the energizing of the concentrator plant with medium-voltage power is scheduled for the end of March 2021.

Advanced, detailed discussions 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 now connected to 220-kV national electrical grid; the first of six turbines at the refurbished Mwadingusha hydropower plant now synchronized to the national electrical grid, providing clean, renewable hydropower
In December 2020, the 35-kilometre-long double circuit 220-kilovolt (kV) power line feeding into Kamoa-Kakula was connected to the national electrical grid through theNew Western Dispatch (NRO) substation in Kolwezi. Kamoa-Kakula’s main 220-kV substation is nearing completion and is expected to be energized by the end of March.

COVID-19 prevention initiatives continue to focus on risk mitigation
Kamoa-Kakula’s prevention measures remain strictly enforced, with further prevention being the focus while the world responds to the latest COVID-19 strains. Rigorous testing, physical distancing, wearing of face masks, frequent hand washing and contact-tracing measures still are in place to protect the safety and health of the workforce and community members.
The project has a well-established COVID-19 isolation facility at the Kamoa Camp. Suspected cases and symptomatic patients are moved to this facility, where they are 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.
Kamoa-Kakula has successfully sourced the latest COVID-19 rapid diagnostic tests (RDT) that test for antigens (the presence of viral particles). The tests are being used by the medical team at Kamoa-Kakula to screen all site arrivals and travellers. Test results are received within an average of 20 minutes, which further enhances the preventative measures already in place.
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 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.

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。
