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.

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 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.

本新聞稿中關于礦堆的其它科學或技術性披露已經由喬治·吉爾克里斯特 (George Gilchrist) 審查和批準，他憑借其教育、經驗和專業協會會籍被認為是NI 43-101 條款下的合資格人士。由于吉爾克里斯特先生是艾芬豪礦業資源部副總裁，因此他并不符合NI 43-101 對獨立人士的界定。吉爾克里斯特先生已核實本新聞稿所披露的其它技術數據。
本新聞稿所載的礦堆品位估算值是基于早前從地下巷道的大塊礦石取樣以及從最近開發的垂直剖面刻槽取樣。每個巷道進行第二次爆破時取樣，并收集3個5公斤重的樣品。從2020年10月起使用刻槽取樣的樣品作為礦堆品位估算的主要數據，大約每15米在整個垂直剖面上使用手持式研磨機按1米垂直增量進行采樣，收集100-150克重的樣品。樣品在項目現場實驗室粉碎后，使用便攜式XRF (pXRF) 儀器進行分析。除了在商業實驗室利用4種酸分解液和ICP-OES進行分析之外，卡莫阿銅業也經常使用pXRF分析其鉆孔巖芯中的銅含量。該數據表明，pXRF結果可用于品位控制和采礦井取樣。
