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 Kakula Copper Mine totalled 1,842 metres in August, bringing the cumulative total underground development completed to date to more than 20.6 kilometres – approximately 6.0 kilometres ahead of schedule.

The majority of the underground development headings at the Kakula Mine currently are traversing medium-grade sections of the orebody, with average grades ranging between 3% and 5% copper. A concentrated effort was made in August to complete the ledging development in the room-and-pillar section of the mine to accommodate critical infrastructure, such as piping and electrical cabling, for the mine’s permanent water-handling system.

The ledging development work will be completed early this month and will allow the mining teams to begin highly-productive stoping operations; however, the development work was in lower-grade ore and resulted in a temporary, modest decrease in overall stockpile grade in August and early September.

The stockpile grade is expected to improve, as planned, beginning this month as the majority of the working areas will transition to the higher-grade ore zones near the centre of the deposit that have copper grades approximately +5% to +8%.

The beneficial handover of the high-capacity ore conveyor system at the Kakula North declines was achieved at the end of July. All of the ore being mined in the northern portion of the Kakula Mine now is transported to surface via the conveyor system and placed on a blended, run-of-mine surface stockpile. The blended stockpile contains 483,000 tonnes grading an estimated 3.76% copper; comprised of 116,000 tonnes of high-grade ore grading 6.08% copper and 367,000 tonnes of medium-grade ore grading 3.02% copper.

Two additional, pre-production ore stockpiles are located at the Kakula South decline (approximately 121,000 tonnes grading 2.36% copper) and the Kansoko decline (approximately 68,000 tonnes grading 2.21% copper). More than 109,000 tonnes of ore was added to the project’s pre-production stockpiles in August.

Surface conveyor systems to transport the ore from the Kakula North stockpile to the processing plant are under construction.

First copper production expected in less than a year

Initial production at the Kakula Mine is scheduled for Q3 2021. Kakula is projected to be the world’s highest-grade major copper mine, with an initial mining rate of 3.8 million tonnes per annum (Mtpa) at an estimated average feed grade well in excess of 6% copper over the first five years of operation.

The Kakula Mine will have one of the most favourable environmental footprints of any tier-one copper mine anywhere in the world. The mine will be powered by clean, renewable hydroelectricity and be among the world's lowest greenhouse gas emitters per unit of copper produced. Kakula also will have a relatively small surface footprint as approximately 55% of the mine’s tailings will be pumped back into underground workings.

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%).

“Together with our joint-venture partners, we look forward to sharing the independently verified engineering and economic studies on September 8th that will showcase why Kamoa-Kakula is, without question, the world’s best new copper project,” said Mr. Friedland. “Kamoa-Kakula is unique as it combines ultra-high-copper grades with thick, shallow, flat-lying ore zones, providing the economies of scale and low mining costs of large, open-pit mining operations, but without the visual environmental impact associated with open-pit mining.”

“We also plan to soon announce the appointment of a leading environmental consulting firm to audit Kamoa-Kakula’s greenhouse gas intensity metrics, providing Environmental, Social and Governance investors with independent and transparent verification of the project’s achievements towards our goal of producing the world’s greenest copper,” Mr. Friedland added.

Kakula Mine development progressing towards zone of +8% copper in centre of deposit

Underground development of the Kakula Mine – the first of multiple, near-surface copper deposits that are planned to be put into production on the 400-square-kilometre Kamoa-Kakula mining licence – is now significantly ahead of schedule. Mine access drives 1 and 2 (interconnected, parallel tunnels that will provide access to ore zones) being driven from the Kakula northern declines continue to advance towards the southern portion of the orebody.

Development of the eastern perimeter drives also is well advanced as are the access drives to the room-and-pillar mining area. Development of twin access drives being driven from Kakula’s southern portal has reached the +5% copper mining zone, with mining crews working to establish the connection of these drives with mine access drives 1 and 2 from the northern side of the orebody. The northern and southern access drives are expected to join in November 2020, which will be a major milestone in the development of the Kakula orebody.

Once the northern and southern access drives are connected, the majority of mining activities will focus on the initial drift-and-fill mining blocks in the centre of the Kakula deposit, where the average grade is higher than 8% copper. Drift-and-fill stoping is a highly-efficient form of underground mechanized mining and will allow the operation to efficiently recover significantly more tonnes from the orebody.

Underground mining with two mining crews also is taking place at the Kansoko Mine, located at the Kamoa deposit, approximately 10 kilometres north of the Kakula Mine.

The construction of Kakula’s second permanent underground water-handling system is nearing completion with the first of four pump trains commissioned in early August; the second pump train was commissioned in the last week of August. The new system adds 800 litres per second of underground pumping capacity, bringing the total installed capacity to 1,400 litres per second. Two additional underground water dams are under construction; one at bottom of the southern declines, and one along the north eastern perimeter drifts.

Ivanhoe plans to issue the independent definitive feasibility study for the development of the 6 Mtpa Kakula Mine on September 8, 2020. The company also will issue a pre-feasibility study, including mining 1.6 Mtpa from the Kansoko Mine, to take full advantage of an expanded plant capacity of 7.6 Mtpa at Kakula. In addition, the company will issue an updated, expanded preliminary economic assessment for the overall development plan of up to 19 Mtpa for all of the copper discoveries made to date at the Kamoa-Kakula Project.

Construction on the processing plant and other surface infrastructure rapidly progressing

Construction of Kakula’s initial, 3.8-Mtpa concentrator plant is progressing well, with approximately 20,000 cubic metres of concrete being poured to date. Concrete bases for the ball mills, flotation plant and the concentrate thickener have been partially handed over to the mechanical contractor to commence installation work, and mechanical erection and installation is underway in most of the plant areas. Structural steel fabrication is complete with more than half of the approximately 6,000 tonnes of structural steel already delivered to site. Fabrication of platework and piping is progressing according to schedule with the first deliveries already on site; platework installation has started.

Total steel prefabricated or installed is approximately 2,000 tonnes. All floor and sidewall plates for the concentrate thickener now are in position, and welding is 40% complete.

Installation of the tailings thickener has commenced, with the centre column being placed in position and welding of the floor plates underway. Pre-assembly of the high-pressure grinding rolls feed bin #1 conveyor has started. Both secondary crushers have been assembled and placed in position. Installation of the first ball mill shell has been completed.

All 21 oversized truck loads of equipment for the processing plant’s primary ball mill ? measuring 9.75 metres (32 feet) long and 6.1 metres (20 feet) in diameter – have arrived on site. The final shipments of the ball mill components are scheduled to arrive at site this month, which will be the final deliveries of long-lead plant equipment.

Beijing-based CITIC Construction is building Kakula’s first-phase, backfill paste plant. The backfill plant will be used to blend 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 55% of the mine’s tailings will be sent back underground, significantly reducing the surface tailings storage.

Construction of the tailings dam has commenced and is progressing well; with the aim to complete most of the earthworks before the rainy season starts in November.

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 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%.

Clean, sustainable hydro-electric power for Kamoa-Kakula

Construction activities at the Mwadingusha hydro-electric power plant, where all six turbines are being replaced, is progressing well; as is the associated 220-kilovolt (kV) infrastructure to supply Kamoa-Kakula with clean hydro-power. The mine is scheduled to be energized with permanent 220kV hydro-generated power in early 2021, well in time for first copper production.

The temporary construction power supply for the Kakula Mine was recently upgraded, including the commissioning of six 2-megawatt (MW) generators to provide back-up power, and the installation of an 18 MW/120-kilovolt (kV) mobile substation to increase the capacity of grid power available at the mine. This will provide sufficient power until the main 220kV power supply is energized. An additional six new 2MW generators have arrived at the port of Durban from China, and are en route to site. The twelve generators will supply the full back-up power requirements for the mine.

Construction of the 220kV supply infrastructure is in progress, including a new 220kV distribution sub-station for the power utility (SNEL); a new 35-kilometre, 220kV power line; and a consumer substation at Kakula with two 80 MW/220kV transformers.

Installing a new alternator in the Mwadingusha hydro-electric power plant. Mwadingusha will soon be delivering 72 MW of clean, sustainable hydroelectricity to the national grid.

Kamoa-Kakula’s COVID-19 readiness initiatives focused on risk mitigation

In accordance with new health guidelines from the DRC government, and in line with the country’s lifting of restrictions, Kamoa-Kakula lowered its quarantine and lockdown measures from level 3 to level 2 on July 27th. The mine’s Congolese workforce have gone back to normal rotation. 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. Any potential symptomatic patients are moved to this facility, where they will be isolated, tested and treated. Once the patient has recovered and is deemed no longer infectious, they can return to work only after an additional quarantine period determined by the project’s medical staff in dedicated quarantine.

As the pandemic evolves, the medical team at Kamoa-Kakula is purposefully reviewing and updating 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 very low.

剛果民主共和國科盧韋齊 — 艾芬豪礦業 (TSX: IVN; OTCQX:IVPAF) 聯席董事長羅伯特·弗里蘭德 (Robert Friedland) 與孫玉峰 (Miles Sun) 今天宣布,卡庫拉銅礦的地下開發持續快速推進,于8月份共掘進1,842米,迄今為止已經完成了20.6公里以上的地下開拓工程,超過既定目標約6.0公里。

目前,卡庫拉礦山的大多數開拓巷道橫貫中品位的礦段,其平均銅品位在3%5%之間。項目于8月份著重在礦山房柱式采礦區建設壁架,以容納礦山永久水處理系統的管道和電纜等重要基礎設施。

壁架工程將于本月初完成,使采掘班組可以盡快展開高效的采礦作業。然而,工程位置的礦石品位較低,因此8月份至9月初的礦堆品位將會暫時稍為下跌。

大多數工作區將于本月過渡到礦床中心附近的高品位礦區,銅品位約為+5%至+8%。因此,礦堆的品位將按計劃進度而有所提升。

卡庫拉北部斜坡道的高負載礦石輸送系統,已于7月底正式運行。目前,所有在卡庫拉礦山北部開采的礦石將經由輸送系統運送到地表的混合礦堆?;旌隙褕瞿壳耙褍涞V石量約483,000噸,銅品位約3.76%,其中包括116,000噸的高品位礦石 (銅品位6.08%) 以及367,000噸的中品位礦石 (銅品位3.02%)。

此外,項目還有兩個額外的投產前礦堆位于卡庫拉南部斜坡道 (121,000噸礦石,銅品位2.36%) Kansoko斜坡道 (68,000噸礦石,銅品位2.21%)。于8月份,項目的投產前礦堆已增加超過109,000噸礦石。

地表輸送系統的施工正在進行中,將從卡庫拉北部的礦堆的礦石運送到選礦廠。

首批銅精礦生產將于一年內實現

卡庫拉礦山計劃于2021年第三季度實現首批精礦生產,預期將會成為全球品位最高的大型銅礦,初始年處理礦量為380萬噸,估計投產后頭5年的平均給礦銅品位達6%以上。

相比任何頂級銅礦,卡庫拉將會是具有最佳環境足跡的礦山之一。它將使用清潔、可再生的水電,并將成為全球每單位銅的溫室氣體排放量最低的礦山之一。礦山約55%的尾礦將被泵送回地下,卡庫拉的地表足跡因此相對較小。

卡莫阿-卡庫拉銅礦項目是艾芬豪礦業(占股39.6%)、紫金礦業集團(占股39.6%)、晶河全球(占股0.8%) 及剛果政府(占股20%) 的合資項目。

弗里蘭德先生說﹕我們期待于98日與我們的合資伙伴一起向外界公布卡莫阿-卡庫拉項目的獨立核實的工程和經濟研究報告,幫助大家了解卡莫阿-卡庫拉為何會是全球最為優秀的新建銅礦項目???/strong>-卡庫拉是獨一無二的,擁有厚大、接近地表和平伏的礦體和超高的銅品位,適合進行大型的露天采礦作業,易于實現規模效益和低采礦成本,且不會造成像露天采礦一樣的、可見的環境影響。

弗里蘭德先生補充說﹕我們還計劃馬上宣布聘請一家領先環保顧問公司的消息,該公司將負責審查卡莫阿-卡庫拉將會產生的溫室氣體強度指標,向關切環境、社會責任和企業治理的投資者提供獨立和透明的調研結論,以證明我們為達到生產世界上最環保銅金屬之一目標所做出的成績。

卡庫拉南面斜坡道的中品位堆礦,目前儲備礦石量約121,000噸,銅品位2.36%。

Kansoko斜坡道的中品位堆礦,目前儲備礦石量約68,000噸,銅品位2.21%。

卡庫拉礦山持續推進開發,將到達礦床中心銅品位8%以上的礦段

卡庫拉礦山是卡莫阿-卡庫拉項目涵蓋的400平方公里開采許可范圍內多個近地表銅礦的首產礦山,地下開采工程持續超計劃高效推進。礦山的1號和2號運輸通道正從卡庫拉北面斜坡道朝著礦體的南部掘進,施工進展順利。兩條運輸通道是相互連接的平行通道,將連通至開采礦段。

同時,東部外圍通道和房柱式采礦區的工程的進展也十分理想。兩條運輸通道已從卡庫拉南部礦坑口到達銅品位高于5%的開采礦段,采掘班組正在將這兩條通道與礦體北部的1號和2號運輸通道連接。南北運輸通道預計于202011月連接完成,將會是卡庫拉礦體開拓工程的重要里程碑。

南北運輸通道連接后,大多數的采礦活動將會集中在卡庫拉礦床中心的首個分層充填采礦區,該礦區的平均銅品位達8%以上。分層充填采礦是一種高效的機械式地下采礦法,可有效地大大提升從礦體采掘的礦石量。

位于卡庫拉礦山以北約10公里,卡莫阿礦區范圍內的Kansoko礦山,目前正有兩隊采掘班組在進行地下采礦工程。

卡庫拉第二永久地下水處理系統的施工將近完成。系統設有4個泵組,第1個泵組已于8月初運行,而第2個泵組也于8月最后一個星期開始運行。新系統將地下泵流量提升每秒800公升,使總裝置容量達到每秒1,400公升。目前正在加建兩個地下水壩,一個位于南面斜坡道的底部,另一個則沿著東北面的周邊平巷建造。

艾芬豪計劃于202098日發布卡庫拉礦山年處理礦量600萬噸開發工程的獨立最終可行性研究報告。同時,公司將會發布包含Kansoko礦山 (年開采礦量160萬噸) 的預可行性研究報告,以充分利用卡庫拉礦區將擴建至年處理礦量760萬噸的選廠產能。此外,公司還將發布卡莫阿-卡庫拉項目至今所有銅礦資源的整體開發計劃(年處理礦量可達1,900萬噸) 的更新和擴充的初步經濟評估報告。

輸送帶工Martin Nkulu正在監控高品位銅礦石經卡庫拉北面斜坡道的輸送系統運送到地表,該輸送系統每小時可輸送2,000噸礦石。

一臺裝載著銅礦石的卡車駛向卡庫拉南面的斜坡道。其中一條南部運輸通道已進入銅品位高于5%的開采礦段,另一條也快將到達。南北運輸通道預計于11月連接完成。
