.Stage 2 Expansion from 200,000 tpa to 400,000 tpa continues to progress well.
•Key equipment received in late-2019, including new production long hole drill, 17t-bucket underground LHD loader, twin boom autodrill development jumbo and integrated emulsion charging unit.
•Arrival of the production long hole drill marks the beginning of Kainantu’s transition from an exclusively cut and fill mine to a high-productivity, lower-cost, long hole open stoping extraction method.
•Primary ventilation system and underground electrical reticulation upgrade completed in December 2019, for a ~3x increase in ventilation fan power, resulting in a more than 100% increase in flow rates and immediate improvement to the mining cycle and operational flexibility.
•Record material movements (mill feed and waste rock) of 120,000 tonnes in Q4 2019 achieved from under 60,000 tonnes in Q1 2019. A key focus has been on waste development for the expansion and there are now seven sublevels established – previously three operating sublevels in 2018.
•Preparation for development of Kainantu Twin Incline has commenced with earthworks underway.
•Final stages of process plant expansion progressing with crusher upgrade, including installation of new secondary crusher largely completed. Additional flotation tank foundations and tank installation is complete, with piping and electricals underway.
