KOLWEZI, DEMOCRATIC REPUBLIC OF CONGO – Ivanhoe Mines (TSX: IVN; OTCQX: IVPAF) Co-Chairs Robert Friedland and Yufeng “Miles” Sun announced today that underground development at the Kamoa-Kakula Copper Project in the Democratic Republic of Congo (DRC) totalled 2,172 metres in October. This marks another new monthly record and brings total underground development to more than 24.7 kilometres – approximately 7.9 kilometres ahead of schedule.
Mr. Friedland and Mr. Sun also noted that mining crews produced a combined 194,000 tonnes of ore in October from the Kakula and Kansoko mines, which was 48% higher than achieved in September. The project’s pre-production surface stockpiles now contain approximately one million tonnes of high-grade and medium-grade ore at an estimated grade of 3.47% copper.
The enormous amount of pre-production development completed to date at both the Kakula and Kansoko mines has positioned the project for a significant acceleration in the tonnage, as well as a marked increase in the grade, of ore added to the project’s surface stockpiles beginning this month.
The monthly total of 2,172 metres of underground development in October was comprised of 1,809 metres at the Kakula Mine and 363 metres at the Kansoko Mine, which is located at the Kamoa Deposit – approximately 10 kilometres north of the Kakula Mine.
At Kakula, both main access tunnels (drives) being advanced from the southern decline, and the spiral access drive being advanced from the northern decline, have recently accessed the high-grade zone near the centre of the deposit grading approximately +8% copper (see figures 1 and 2).
Kakula’s main access drives between the northern and southern declines have less than 100 metres remaining before they are connected (holed) in the high-grade centre of the deposit. The holing will significantly increase ventilation to the centre of the orebody, allowing for additional mining crews to begin highly-productive mining operations in Kakula’s high-grade ore zones.
Mark Farren, CEO of Kamoa Copper said: “We are encouraged with the current development performance. We remain on track to open up sufficient high-grade reserves in time to feed our phase 1 and 2 concentrator plants with high-grade copper ore.”
“The imminent joining of Kakula’s northern and southern main access drives will be a major milestone in the mine’s development. Once this is achieved, the opening up and ledging of the drift-and-fill blocks can commence in the high-grade core of the deposit, where the average grade is projected to exceed 8% copper,” Mr. Farren added.
In addition to advancing the main connecting access drives, underground mining crews at Kakula are focused on preparation work for 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 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 mining crews to deliver significant tonnage of high-grade ore directly from Kakula’s underground workings to the processing plant.
Kakula’s second underground ore bin (the west tip bin) is undergoing commissioning. Installation of Kakula’s ventilation shaft #2 also is progressing well, with the first of three high-capacity surface fans installed by the contractor.

The gabion wall for the surface bulk reclaim tip system that is located near Kakula’s main northern decline has been constructed and preparation has started for the civil works required at the top of the wall. The bulk reclaim tip system will be used to feed ore from Kakula’s surface stockpiles (and ore from the Kansoko Mine when second-phase operations begin) to the processing circuit.
Underground development at the Kansoko Mine currently is in low-to-medium-grade ore zones, grading approximately 3% copper. In October, mine development work intersected the first exposure of siltstone, marking the transition to higher copper grades at Kansoko. 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 Q2 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.
A recent, 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.

October’s ore production 48% higher than September; pre-production surface ore stockpiles now total approximately one million tonnes
In October, mining crews at the Kakula and Kansoko mines mined and transported to surface approximately 194,000 tonnes of ore grading 4.01% copper. This brings the project’s total pre-production high- and medium-grade ore stockpiles to approximately 1,000,000 tonnes at an estimated grade of 3.47% copper. An additional 622,000 tonnes of low-grade development ore also has been stockpiled on surface.
October’s ore production is approximately 48% higher than the 132,000 tonnes grading 3.31% copper mined in September, and approximately 78% higher than the 109,000 tonnes grading 2.96% copper mined in August. The project is positioned for a significant acceleration in the tonnage, as well as a marked increase in the grade, of ore added to the surface stockpiles as more mining crews soon will begin working in the higher-grade areas of the Kakula and Kansoko mines.

Civil works for the initial concentrator plant are nearing completion, with approximately 26,000 cubic metres of concrete poured to date. All major construction areas will be handed over to the steel, mechanical, piping and platework (SMPP) contractor imminently.
The final major pieces of equipment ? two 80-MVA/220kV electrical transformers ? are in transit and expected on site shortly. Construction of the various electrical substations is progressing well.
Structural steel and platework fabrication for the concentrator plant is complete, with the bulk of the material already delivered to site. Piping is progressing according to schedule, with more than 60 kilometres (of a total of 83 kilometres) of piping already delivered. Limited electrical, controls and instrumentation (EC&I) work has started with the installation of cable racking.
Over 2,000 tonnes of steel (of a total of 5,700 tonnes) has been installed. The main focus areas are the conveyor gantries, mill building, reagent storage area, flotation area, and concentrate storage building. Construction has commenced for the plant stores, workshop and water services.

Beijing-based CITIC Construction is building Kakula’s first phase, backfill paste plant. 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 backfill plant civil works is well advanced and steel erection has started.
Construction of the tailings dam is progressing well, with the aim to complete most of the earthworks before the rainy season begins later this month. Installation is well advanced for the three tailings lines and the tailings return water line.
The long-lead items for the second 3.8 Mtpa concentrator plant have been ordered and the second phase of the project’s development is officially underway. Requests for tenders for the second-phase earthworks and civil works also have been issued.

Discussions underway for the marketing of Kakula’s copper concentrates
Kamoa-Kakula is in detailed discussions with a number of parties with respect to the marketing and smelting 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 expected to be connected to the national power grid in December, providing clean, renewable 220-kV hydropower
In December 2020, Kamoa-Kakula is expected to tie in the 35-kilometre, 220-kilovolt (kV) power line connecting theWestern Dispatch substation in Kolwezi to Kamoa-Kakula, and supply the project with reliable and clean hydro-generated electricity from the national grid.
The upgrading work at the 72-megawatt Mwadingusha hydropower plant is nearing completion and electricity from all of Mwadingusha’s six turbines is expected to be integrated into the national power grid in the first quarter of 2021. The work is being conducted by engineering firm Stucky, of Lausanne, Switzerland, under the direction of Ivanhoe Mines and Zijin Mining Group, in conjunction with the DRC’s state-owned power company, La Société Nationale d’Electricité (SNEL).

Kamoa-Kakula’s COVID-19 prevention initiatives focused on risk mitigation
In accordance with health guidelines from the DRC government, and in line with the country’s lifting of restrictions, Kamoa-Kakula’s Congolese workforce has gone back to normal work rotations. 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. All expatriate employees are still required to quarantine for two weeks upon arrival at Kamoa-Kakula.
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, if there was 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.

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。
