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 269,000 tonnes of ore grading 5.36% copper in December from the Kakula and Kansoko mines. The tonnage was 7.6% higher than November, while the copper grade was 10.5% higher.
The project’s pre-production surface stockpiles now contain approximately 1.52 million tonnes of high-grade and medium-grade ore at an estimated blended grade of 4.03% copper. Contained copper in the stockpiles increased by approximately 14,400 tonnes in December – a 30.9% increase over November’s production reflecting the increased mining in the ultra-high-grade centre of the Kakula Deposit – to a cumulative total of more than 61,000 tonnes (the current copper price is approximately US$7,900 a tonne).
The project 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.
Mr. Friedland and Mr. Sun also noted that the project team established another new monthly record for underground mine development in December with a total of 2,792 metres of advancement – 620 metres more than the previous monthly high achieved in October 2020. Another important development milestone was achieved in late December with the second holing of Kakula’s northern and southern access tunnels, establishing additional access to mine Kakula’s high-grade ore in the centre of the orebody grading +8% copper.
“After more than 26 years of continuous efforts, Ivanhoe Mines and its joint-venture partners are less than six months away from initial production at Kamoa-Kakula – the first world-scale copper discovery on the African continent in generations. This year’s transformation marks the beginning of the next chapter of our journey that began in 1994 and has involved thousands of dedicated and talented people,” said Mr. Friedland. “Underground development at the Kakula Mine is well ahead of schedule and construction of the first phase processing plant is on schedule to produce exceptionally high-grade and clean copper concentrates beginning this July. The performance of Kamoa Copper’s multinational management team in successfully navigating the profound logistical challenges posed by the global COVID-19 pandemic has been absolutely outstanding.”
“Our expectations are for continued rising copper prices through 2021 and beyond; as such, the timing of Kamoa Copper’s first production is fortuitous given that the project is scheduled to have ore stockpiles containing more than 125,000 tonnes of contained copper available for processing by July 1st. A rising copper price directly impacts the realizable value of the contained copper in the stockpiles, the cost of which is capitalized,” Mr. Friedland added.
December’s record-setting advancement brings total underground development to approximately 29.8 kilometres – approximately 10.5 kilometres ahead of schedule. The monthly underground development in December was comprised of 2,521 metres at the Kakula Mine and 271 metres at the Kansoko Mine.
Mark Farren, Kamoa Copper’s CEO, commented: “A terrific performance by our mining teams in December and an exceptional way to end 2020. To achieve a record-setting month in the midst of the holiday season is a testament to the commitment and professionalism of our people. The start of 2021 brings with it a sense of excitement and opportunity as we begin to shift our focus from mine development to production.”
“Mining crews recently entered a remarkably thick zone of high-grade ore grading +8% copper in the centre of the Kakula Mine, which has allowed us to enlarge the development drifts in this area to 10 metres high by 7.5 metres wide (75 square metres), and the increase in ore tonnes per metre of development has been substantial,” Mr. Farren added.
Kakula’s combined medium-grade and high-grade ore mined in December was approximately 245,000 tonnes at an average grade of 5.64% copper, including approximately 55,000 tonnes grading 8.75% 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 the high-grade 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 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 December was approximately 24,000 tonnes at an average grade of 2.49% copper. Priorities at Kansoko during December were to develop and support major ventilation airways towards the mine’s No. 1 ventilation shaft. 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.

Miners operating a jumbo drill at the face of a high-grade development drift near the centre of the Kakula Mine. Due to the thickness of the copper ore in this area, the drifts are 10 metres high by 7.5 metres wide (32.8 feet high by 24.6 feet wide), or 75 square metres. For perspective, the height of the drift is close to the height of a standard telephone pole. The average grade of ore in this area is 8.75% copper and the tonnage per blast is approximately 1,000 tonnes, more than double the tonnage per blast in a normal drift.
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.
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%).
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.
December’s ore production was 7.6% higher than November, with monthly copper grade increasing from 4.85% to 5.36%; pre-production surface ore stockpiles now total approximately 1.52 million tonnes grading 4.03% copper
In December, mining crews at Kakula and Kansoko mined and transported to surface stockpiles approximately 269,000 tonnes of ore grading 5.36% copper. This brings the project’s total pre-production high- and medium-grade ore stockpiles to approximately 1.52 million tonnes at an estimated blended grade of 4.03% copper. An additional 622,000 tonnes of low-grade development ore also has been stockpiled on surface.
December’s ore production was approximately 7.6% higher than the 250,000 tonnes grading 4.85% copper mined in November, and approximately 38% higher than the 194,000 tonnes grading 4.01% mined in October.

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 the national power grid, providing clean, renewable 220-kV hydropower; first of six turbines at the refurbished Mwadingusha hydropower plant now synchronized to the national grid
In December, Kamoa-Kakula was connected to the national power grid with the energizing of the 35-kilometre, 220-kilovolt (kV) power line connecting theWestern Dispatch substation in Kolwezi to Kamoa-Kakula, supplying the project with reliable and clean hydro-generated electricity.

Ivanhoe Mines Energy DRC is pleased to announce that the first of six new turbines at the Mwadingusha hydropower plant was synchronized to the national electrical grid in December. Commissioning of the plant’s remaining five generating units, in sequence, soon will begin to ensure that Kamoa-Kakula’s power requirements are met ahead of the commissioning of the concentrator plant. The fully-refurbished hydropower plant is expected to deliver approximately 72 megawatts of power to the national grid.
Ivanhoe Mines Energy DRC achieved a significant milestone in December when the first of six turbines at the Mwadingusha hydropower plant began delivering clean, hydropower to the national electrical grid.
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 strain. Rigorous testing, physical distancing, wearing of 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 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。
