Ivanhoe Mines announced 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.

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 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.

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%).
