As a result of the impact on underground pumping and electrical infrastructure, to date, there has been an increase in water inflow levels into the Kakula underground mine. Kamoa Copper, with support from Ivanhoe and Zijin Mining, is currently preparing detailed dewatering plans, including the acquisition of additional pumping equipment to increase pumping capacity and allow for dewatering from surface. Ivanhoe would like to thank its Chinese partners Zijin and CITIC Metal for their assistance in procuring additional equipment for the dewatering efforts. Ivanhoe Mines' President and Chief Executive Officer, Marna Cloete commented: \"I would like to extend my profound thanks to our dedicated workforce, who have shown exceptional resilience and commitment while working under challenging conditions during the recent seismic ac...
