rock-handling system (tips, bins and conveyors) is progressing well and is targeted for completion in Q2-2020. Work on Kakula’s main decline dam and pumping station has been completed, and work on the main decline bottom dam is well advanced. By the end of September 2019, 571 m of develop- ment had been completed at the southern ventilation decline, which will facilitate the acceleration of criti- cal early mine development. Other engineering and construction activi- ties underway at Kamoa-Kakula include the refurbishment of six turbines at the Mwadingusha hydro-electric power plant and associated 220-kV infrastructure to supply the mine with clean hydro- power, construction of a permanent road between the mine site and the Kolwezi airport, construc- tion of the first phase of accommodation for 1 000 employees and contractors, and earthworks for the processing plant and other surface infrastructure. The scale of the Kakula project is considerable. On February 6, 2019, Ivanhoe announced the results from the Kakula 2019 PFS. The life-of-mine produc- tion scenario detailed in the study provides for

performed by mining crews operating large-capacity, semi-autonomous mining equipment, such as jumbo drilling rigs and 50-tonne trucks. More than 5 km of underground development was completed in the nine months ended September 30, 2019. Development ore is being stockpiled on surface near the site of the concentrator plant. This ore will be used for plant commissioning as well as sup- plying any gap in the production build-up once the concentrator is operational. Mine access drives 1 and 2 (interconnected, par- allel tunnels that will provide access to ore zones) continue to progress, with access drive 2 having reached the high-grade zone. The number of underground mining crews has increased from three at the start of the third quarter, to six now working at Kakula. The project will con- tinue to add additional crews over the next 12 months to further accelerate development. Ventilation shaft 1 has been fully commissioned and work on ventilation shafts 2 and 3 is well advanced, with underground access for both having been achieved and pilot drilling started.
