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 continues to exceed expectations with more than 18.7 kilometres now complete, which is 5.5 kilometres ahead of schedule. In July, the mining team achieved 1,638 metres of underground development 257 metres ahead of plan for the month.

The majority of the development headings at the Kakula Mine currently are traversing medium-grade sections of the orebody, with average grades ranging between 3% and 5% copper. Several development headings are in higher-grade zones averaging between 5% and 8% copper, and this ore is being placed on a dedicated, high-grade surface stockpile at Kakula North that currently totals approximately 116,000 tonnes grading an estimated 6.08% copper. The lower-grade surface stockpiles at Kakula North, Kakula South and Kansoko together contain an additional 446,000 tonnes grading an estimated 2.73% copper.

As Kakula’s underground development progresses over the next few months, the majority of the working areas are expected to transition into the higher-grade ore zones near the centre of the deposit that have copper grades approximately 5% to 8%.

The high-capacity ore conveyor system at the Kakula North declines, which has a capacity of 2,000 tonnes per hour, is undergoing final commissioning and is expected to begin continuous operations shortly. Once this happens, the ore mined in the northern portion of the Kakula Mine will be combined and be placed on a blended surface stockpile. The Kakula South and Kansoko declines are not equipped with conveyor systems; as such, the ore mined from these deposits will continue to be placed on separate surface stockpiles, based on copper grades.

First copper production at Kakula approximately one year away

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 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. It will be powered by clean, renewable hydroelectricity and be among the world's lowest greenhouse gas emitters per unit of copper produced. It also will have a relatively tiny surface footprint as approximately 55% of the mine’s tailings will be pumped back into underground workings.

The Kamoa-Kakula Project is unique as it combines ultra-high copper grades in thick, shallow and relatively flat-lying deposits – allowing for large-scale, highly-productive, mechanized underground mining operations.

More than 300 truckloads, consisting mainly of structural steel and equipment for Kakula’s initial 3.8-million-tonne-per-annum processing plant, are expected to arrive at the mine site before the end of August. Fabrication of the plant’s largest components – two ball mills, each measuring 9.75 metres (32 feet) long and 6.1 metres (20 feet) in diameter – has been completed at CITIC Heavy Industries’ factory in Luoyang, China, and the third and final shipment of ball mill components is expected to be on-site by the end of September.

“The construction team at Kakula, led by Mark Farren, Kamoa Copper’s CEO, has done a fantastic job of keeping the project moving ahead at a rapid pace despite the logistical challenges posed by COVID-19,” said Mr. Friedland. “With each passing month, we are getting increasingly confident that we could be producing copper at Kakula ahead of schedule.”

“We're in a good place at the moment, with the vast majority of the major equipment needed to build the mine and processing plant already fabricated, and either at site, or en route to site. Full credit goes to our entire team for implementing and adhering to early and extraordinary measures to safeguard our workforce and mitigate the impact of COVID-19 on the mine development and construction operations,” Mr. Friedland added.

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%).

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 well ahead of schedule. Mine access drives 1 and 2 (interconnected, parallel tunnels that will provide access to ore zones) continue to advance towards the southern portion of the orebody.

Development also is well advanced on the eastern perimeter drives and the room-and-pillar mining area. Development from the southern portal has reached south access drives 1 and 2, with mining crews working to establish the connection of these drives with mine access drives 1 and 2 from the north side of the orebody. The northern and southern access drives are expected to be joined in Q4 2020.

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 recover significantly more tonnes from the orebody.

Underground mining also is taking place at the Kansoko Mine, located at the Kamoa deposit, approximately 10 kilometres north of the Kakula Mine. More than 220 metres of advancement was achieved at Kansoko during July by a young Congolese mining crew undergoing training. A second mining crew will be added at Kansoko in August 2020 as the project increases the pace of training new Congolese miners.

The construction of Kakula’s second permanent underground water-handling system is progressing well and commissioning is expected this month. The new system will add 800 litres per second of underground pumping capacity, bringing the total installed capacity to 1,400 litres per second. As mine development progresses, additional underground water dams are planned for the northern and southern perimeter drifts.

The independent Kakula definitive feasibility study (DFS) and an updated Integrated Development Plan for the entire Kamoa-Kakula mining complex is expected to be finalized shortly. The Integrated Development Plan will include details on the planned expansion phases for the greater Kamoa-Kakula mining complex, incorporating updates for mineral resources, production rates and economic analysis.

Basic engineering design and costing for Kamoa-Kakula’s planned Phase 2 expansion, taking production from 3.8 Mtpa to 7.6 Mtpa, also is complete. The scope of facilities for Phase 2 includes underground expansion at the Kakula Mine to reach an annual production rate of 6 Mtpa, the expansion of mining operations at the Kansoko Mine to a steady state 1.6 Mtpa, a second 3.8-Mtpa concentrator plant at Kakula, as well as associated surface infrastructure to support the expansion at the various sites.

Construction on the processing plant and other surface infrastructure remains on track for initial production in Q3 2021

Construction of Kamoa’s 3.8-million Mtpa concentrator plant is progressing well, with more than 16,000 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 steel erection is currently underway in the flotation and thickener areas. Approximately 3,600 tonnes of structural steel had been shipped by the end of July.

Beijing-based CITIC Construction has been awarded the construction contract for Kakula’s phase 1 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.

The Electrical & Instrumentation contract was recently awarded to T3 Construction, a leading South African construction company. This is the final major construction contract required for Kakula’s processing and backfill plants.

Construction of the tailings dam has commenced and is progressing well. The aim is 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%.

“In roughly one year, the Kakula Mine will be producing extremely high-grade concentrate containing over 55% copper with essentially zero arsenic − it will be the ‘beluga caviar’ of copper concentrates,” Mr. Friedland commented. “We expect that there will be intense competition amongst copper traders and smelters to acquire the product before our joint-venture with Zijin Mining builds our state-of-the-art, direct-to-blister smelter.”

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 five new 2MW generators to provide back-up power, and the installation of an 18MW/120kV 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.

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

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. This means that 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.

In July, the Kamoa-Kakula Project donated 10,000 Covid-19 rapid test kits to local community health clinics and placed an order for 15,000 fabric face masks for donation to local communities.

As part of Kamoa-Kakula’s COVID-19 readiness initiatives, the project has procured a polymerize chain reaction (PCR) device from German-based Bosch (a similar device to the GeneXpert). The device arrived on-site at the beginning of July, with an initial supply of 500 tests. The device’s capacity is 15 tests per 24-hour period.

PCR tests are used to directly detect the presence of the genomic material of SARS-COV-2, rather than the presence of the body’s immune response, or antibodies. By detecting viral RNA, which will be present in the body before antibodies form or symptoms of the disease are present, the tests can tell whether or not someone has the virus very early on.

Early detection of potential cases based on symptoms and contact tracing is imperative.

PCR tests give the project’s medical team a good indication of who is infected. This allows for fast isolation, and contact tracing of potential additional cases for quarantine.

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.

刚果民主共和国科卢韦齐— 艾芬豪矿业(TSX: IVN; OTCQX:IVPAF) 联席董事长罗伯特·弗里兰德(Robert Friedland) 与孙玉峰(Miles Sun) 今天宣布,卡库拉铜矿的地下开发持续快速推进,目前已经完成了18.7公里以上的地下开拓工程,超过既定目标5.5公里。采矿团队7月份共掘进1,638米,比月度计划领先257米。

目前,卡库拉矿山的大多数开拓巷道横贯中品位的矿段,其平均铜品位在3%5%之间。部分开拓巷道继续延伸至较高品位矿段,平均铜品位在5%8%之间。这些矿石已运送到位于卡库拉北部的专设的高品位地表堆场,该堆场目前已储备矿石量约116,000吨,铜品位约6.08%。此外,卡库拉北部、卡库拉南部和Kansoko的较低品位地表堆场合共储备矿石量446,000吨,铜品位约2.73%

在接下来的几个月,卡库拉将继续推进地下开发,预计大多数巷道将会到达矿床中心附近的较高品位矿段,铜品位约在5%8%之间。

卡库拉北部斜坡道的高负载矿石输送系统,每小时可输送2,000吨矿石,现正进行最终调试,预计很快将开始平稳运行。系统运行后,在卡库拉矿山北部开采的矿石将被混合并放置在地表混合矿堆。卡库拉南部和Kansoko斜坡道目前没有输送系统,因此在这些矿床开采的矿石将会根据铜品位被堆放在单独的地表堆场。

卡库拉矿山将于一年内实现首批铜生产

卡库拉矿山计划于2021年第三季度实现首批生产,预期将会成为全球最高品位的主要铜矿。卡库拉的初始年处理量为380万吨,估计于首5年运营期间平均原矿铜品位达6%以上。

相比任何顶级铜矿,卡库拉将会是最有利于环境足迹的矿山。它将使用清洁、可再生的水电,并将成为全球每单位铜温室气体排放量最低的矿山之一。矿山约55%的尾矿将被泵送回地下,地表足迹因此相对较小。

卡莫阿-卡库拉项目是独一无二的,拥有矿体厚大、接近地表和相对平伏的矿床及超高的铜品位,适合进行大规模和高效的机械化地下采矿作业。

装载着大部分钢结构和设备的300多辆卡车预计于8月底前将会运抵卡库拉年处理量380万吨的初始选矿厂。选矿厂内最大设备 — 两台球磨机 (直径分别为9.75/32英尺和6.1/20英尺),由中信重工在中国洛阳的工厂铸造完成,球磨机组件的第三批(也是最后一批)预计于9月底运抵矿场。

弗里兰德先生说﹕“尽管COVID-19疫情造成了物流方面的困难,但卡库拉施工团队在卡莫阿铜业首席执行官马克·法伦(Mark Farren)的领导下表现出色,使项目得以快速推进。随着矿山每个月的开发进展,我们更有信心卡库拉将会领先计划提早实现铜生产。”

弗里兰德先生补充说﹕“目前,我们已经准备就绪,建设矿山和选矿厂的大部份主要设备已制造完成,并已运抵矿场或正在运送途中。这全部归功于我们的全体员工上下一心、第一时间实施和遵守严格的防疫措施,以保护员工并减轻COVID-19 对矿山开发和施工作业的影响。”

卡莫阿-卡库拉铜矿项目是艾芬豪矿业(占股39.6%)、紫金矿业集团(占股39.6%)、晶河全球(占股0.8%) 及刚果政府(占股20%)的合资项目。

最近抵达矿场的部分卡车装载着卡库拉矿山所需设备。另有300辆卡车定于8月底前抵达矿场。

卡库拉矿山的鸟瞰图,显示投产前的堆矿量和品位。目前,高品位矿堆储备矿石量约116,000吨,铜品位6.08%。中品位矿堆储备矿石量约325,000吨,铜品位2.94%

在接下来的几个月,卡库拉和Kansoko矿山将继续推进地下开发,预计项目的中品位矿堆将会提升铜品位至3%5%之间。

卡库拉南部斜坡道及中品位矿石堆场,目前已储备矿石量约75,000吨,铜品位2.18%

Kansoko斜坡道及中品位矿石堆场,目前已储备矿石量约46,000吨,铜品位2.17%

卡库拉矿山持续推进开发,将到达矿床中心铜品位8%以上的矿段

卡库拉矿山是卡莫阿-卡库拉项目涵盖的400平方公里开采许可范围内多个近地表铜矿的首产矿山,地下开采工程持续超计划高效推进。矿山的一号和二号运输通道正朝着矿体的南部掘进,施工进展顺利。两条通道是相互连接的平行通道,将连通至开采矿段。

同时,东部外围通道和房柱式开采范围的工程也进展理想。南部矿坑口的工程已经到达南部一号和二号运输通道,采矿团队正努力将这两条通道和矿体北部的一号和二号运输通道连接。南北运输通道预计于2020年第四季度连接完成。

南北运输通道连接后,大多数的采矿活动将会集中在卡库拉矿床中心的首个分层充填采矿区,该矿区的平均铜品位达8%以上。分层充填采矿是一种高效的地下机械采矿法,大大提升从矿体采掘的矿石量。

位于卡库拉矿山以北约10公里,卡莫阿矿床范围内的Kansoko矿山也在开展地下采矿工程。一支由刚果青年矿工组成的采矿队伍在Kansoko矿进行培训,并于7已掘进超过220米。随着项目加快步伐新晋的刚果矿工,第二支队伍将于20208月加入Kansoko矿。

卡库拉第二永久地下水处理系统的施工进展顺利,预计于本月开始运行。新系统将地下泵流量提升每秒800公升,使总装置容量达到每秒1,400公升。随着矿山开发的进展,将计划在北部和南部的周边平巷加建地下水坝。

卡库拉矿山的独立最终可行性研究 (DFS) 和卡莫阿-卡库拉矿群的综合开发计划更新版将尽快完成。综合开发计划将包括卡莫阿-卡库拉矿群后续扩产的计划细节,并将纳入最新的矿产资源、生产规模和经济分析数据。

卡莫阿-卡库拉计划从年处理量380万吨提升到760万吨的第二序列扩建,基本工程设计和成本估算已经完成。第二序列的工程设施范围包括卡库拉矿山的地下扩建以​​达到600万吨年产率、将Kansoko的采矿作业提升至年处理量1,600万吨的稳态生产、在卡库拉矿山建设第二座年处理量380万吨的选矿厂,以及支持各个矿场实施扩建的相关地表基础设施。

选矿厂和其他地表基础设施的施工进度顺利

将按计划于2021年第三季度实现投产

卡莫阿年处理量 380 万吨选矿厂的施工进展顺利,至今已灌入16,000立方米以上的混凝土。球磨机、浮选厂和精矿浓密机的混凝土底座部分已交给机械承包商开始进行安装,且浮选厂和浓密机区域正在搭建钢架。截至7月底,已运抵约3,600吨的钢结构。

卡库拉项目第一序列回填厂的建设合同已授予总部位于北京的中信建设。回填厂将选矿厂的尾矿与水泥混合制造回填浆。回填浆将会泵回矿山用作填充采空区。矿山约55%的尾矿将被泵送回地下,大大减少地表的尾矿量。

电气和仪表器合同最近已授予南非领先的建筑公司T3 Construction。这是卡库拉选矿厂和回填厂所需的最后一份主要建设合同。

尾矿坝已开始施工且进展顺利,目标是要在11月雨季开始前完成大部分的土方工程。

关于卡库拉铜精矿销售方案的讨论正在进行中

目前,卡莫阿-卡库拉正与多方就铜精矿的销售和冶炼方案进行详细讨论。卡库拉将会生产极高品位的清洁铜精矿,将会是世界各地铜冶炼厂渴求的高质量产品。冶金测试结果显示,按全球标准,卡库拉精矿的含砷量极低,约为0.01%

弗里兰德先生说:“大约一年后,卡库拉矿山将会生产出极高品位的精矿,铜品位达55%以上且砷含量接近零,可以说是铜精矿中的'极品鱼子酱'。我们预期,在我们与紫金矿业的合资企业兴建先进的直接粗铜冶炼厂之前,铜金属贸易商和冶炼厂早就会争相采购我们的精矿。”

卡莫阿-卡库拉项目的清洁、可持续水电

Mwadingusha 水电厂的施工进度可观,当前正在进行全部6台涡轮机的更换。同时,220千伏的相关基础设施工程进展顺利,将为卡莫阿-卡库拉矿山提供清洁的水电能源供给。计划于2021年初达到220千伏永久性水力发电能力,其时间表预计将与矿山的首批铜精矿生产进度完美匹配。

卡库拉矿山的临时建设电源最近已进行升级,包括调试了五台全新的2兆瓦发电机以提供后备电源,并已安装18兆瓦/ 120千伏的移动变电站,以增加矿山可用的电网容量。这将在220千伏主要电力投入使用前提供足够的电源。

220千伏供电基础设施的建设正在进行中,包括﹕用于电力公司 (SNEL) 220千伏新配电变电站、一条35公里长的220千伏新输电线,以及一座位于卡库拉的用户变电站 (设有两个80兆瓦 / 220千伏的变压器)

卡莫阿-卡库拉项目的COVID-19应对举措以减低风险为重点

根据刚果政府的新卫生指引,并配合该国解除的部分限制,卡莫阿-卡库拉于727日将其检疫和封锁隔离措施从第3级降低到第2级,即表示矿山的刚果员工已经恢复正常的换班安排。矿山继续实施防疫措施如严格测试、保持距离、常戴口罩、经常洗手和接触者追踪调查等,以保护员工和社区成员的安全和健康。所有外籍员工抵达卡莫阿-卡库拉后仍需进行检疫隔离两个星期。

卡莫阿-卡库拉项目于7月向当地社区诊所捐赠了10,000Covid-19快速检测试剂盒,并已订购了15,000个布口罩,将会捐赠给当地社区。

作为卡莫阿-卡库拉的COVID-19应对举措的一部分,矿山已从德国博世公司采购了一台聚合酶链式反应技术 (简称PCR) 设备(类似于GeneXpert的设备)。该核酸检测设备已于7月初运抵矿场,初步可做500次检测,每24小时可进行15次检测。

PCR检测可直接检出抗原的存在,而并非人体免疫反应或抗体的存在。通过检测体内的病毒核酸 (在抗体形成或出现病症之前已存在体内)PCR检测可判断患者是否早已感染病毒。

目前最重要的是及早测试出现病症和曾与患者接触的潜在感染者。项目的医疗团队可透过PCR检测得知相关人士是否感染。这样可以尽快将其隔离,同时追查其他潜在感染者且实施检疫。

项目已在卡莫阿营地设有COVID-19隔离设施。任何疑似或出现病症的人员都将会安排到该设施,进行隔离、检测和治疗。患者康复且不再具传染性后,只能在项目医务人员订立的额外隔离观察期后才可返回工作岗位。

随着疫情的变化,卡莫阿-卡库拉的医疗队伍正积极审阅和更新其疫情防控方案。项目的防疫措施符合最高国际标准,即使内部出现感染病例,传播或交叉感染的风险也非常低。
