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 17 kilometres now complete, which is 5.1 kilometres ahead of schedule. In June, the mining team achieved 1,729 metres of underground development 575 metres ahead of plan for the month.

Kakula’s 2,000-tonne-per-hour ore conveyor system began operations in June, which will further increase the mine’s pace of underground development.

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 continuing in high-grade zones grading more than 8% copper, and this ore is being placed on a dedicated, high-grade surface stockpile at Kakula North that now totals approximately 68,000 tonnes grading an estimated 5.90% copper. The medium-grade surface stockpiles at Kakula North, Kakula South and Kansoko together contain an additional 394,000 tonnes grading an estimated 2.71% copper.

As Kakula’s underground development progresses over the next few months, the majority of the headings are expected to transition into the high-grade ore zones.

More than 200 truck loads, consisting mainly of structural steel and equipment for Kakula’s initial 3.8-million-tonne-per-annum processing plant, were received on site in June and construction of the plant is progressing rapidly. 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 shipping of the components is underway.

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’s high-capacity ore conveyor system begins operation

Kakula’s decline conveyor system that will transport ore from underground to surface now is operational. Final commissioning of the full system (including the fire suppression system and all safety components) is underway and is scheduled to be completed around mid-July. The conveyor system has the capacity to transport 2,000 tonnes of ore per hour from underground to surface.

The conveyor system substantially shortens the haulage distance for the mine’s truck fleet; significantly increasing productivity, and lowering mining and maintenance costs.

Construction of the surface conveyor system has commenced and the first steel has been delivered to site. The surface conveyor system will transport ore from the decline conveyor system to the main processing plant stockpile. Forecast completion date is scheduled for Q1 2021.

Development of the Kakula Mine, the first deposit to be placed 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 progress well 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 scheduled to be joined by the end of October 2020.

Underground mining also is occurring at the Kansoko Mine, located at the Kamoa deposit approximately 10 kilometres north of the Kakula Mine. Kansoko is development ready and currently is being used to train young Congolese mining crews.

The main surface exhaust ventilation fans (VS#2) are progressing well with fan fabrication on schedule and the ventilation shaft raise boring complete. The NE#1 fan station pilot hole has commenced with fabrication of the fans scheduled to start this month. The third underground water pumping train at Kakula’s main decline pumping chamber has been commissioned, increasing the mine’s pumping capacity to 600 litres per second.

In parallel with the construction of Kamoa-Kakula’s phase 1 Kakula Mine, work is progressing on the independent Kakula definitive feasibility study (DFS) and an updated Integrated Development Plan for the entire Kamoa-Kakula mining complex, which is expected to be finalized this month. 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.

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

Construction of Kamoa’s 3.8-million tonne-per-annum (Mtpa) concentrator plant is progressing well, with more than15,000 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 from China by end of June.

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 during the dry season before the rainy season starts in November.

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 (kVA) infrastructure to supply the mine 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. The transformers are presently being factory tested and prepared for shipment to site.

A new access road from the city of Kolwezi to the Kansoko and Kakula mines was recently completed and is now open to traffic.

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

More than 3,500 employees and contractors currently are working on site, of which approximately 90% are Congolese nationals. To date, Kamoa-Kakula has had no confirmed COVID-19 cases.

As part of Kamoa-Kakula’s COVID-19 readiness initiatives, the project has procured a polymerize chain reaction (PCR) device from German-based Bosch (similar device to the GeneXpert). The device is scheduled to arrive this week, 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 an antigen, 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 will 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 suspected or symptomatic cases are moved to this facility, where they are isolated, treated and tested. 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.

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 standard and if there was a case internally, the risk of spreading or cross contamination is very low.

卡莫阿-卡库拉项目的COVID-19应对举措以减低风险为重点

目前,超过3,500名员工和承包商在矿场工作,其中约90%为刚果国民。至今为止,卡莫阿-卡库拉项目尚未出现任何 COVID-19确诊病例。

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)。该设备预计于本周送达矿场,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 (在抗体形成或出現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。项目的医疗团队将可透过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。

矿山已在卡莫阿营地建设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隔离点,进行隔离、治疗和检测。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。

卡莫阿-卡库拉项目附近的Mumba养鱼场和蔬菜种植场。矿山在当地实施的社会经济援助项目很大部分针对粮食安全、教育和技能发展。卡莫阿-卡库拉的生计计划已发展成为大规模的援助项目,帮助数百名居民从事养鱼、种植玉米和蔬菜,以及出售家禽和蜂蜜。
