About

Chris Muller has over 25 years mining and exploration experience in underground, open cut and surface operations in multiple nations. Chris commenced his already highly rewarding career with Ivanhoe Mines (formerly Indochina Goldfields) in Indonesian Borneo, before working at the Wassa Gold Mine, Ghana with Glencar Mining. He then spent a number of years in Mongolia, with Ivanhoe Mines, in the vicinity of Oyu Tolgoi. For the past 20 years, Chris has been committed to Papua New Guinea, being a leader in key mine (re)starts and resource development, prior to joining Tolu. He was directly involved in the discovery of multiple new porphyries with the Morobe Mining Joint Venture (a 50:50 partnership between Harmony Gold and Newcrest), resulting in the world class status of the Wafi/Golpu Au/Cu/Mo deposit. With K92, he was a co-recipient of the prestigious Thayer Lindsley Award for the discovery of Kora North, now one of the world's highest grade gold operations. During his time with K92, the company defined three major resources at Kora/Judd deposit, Blue Lake Porphyry and the imminent resource at Arakompa. Chris has first class honours in economic geology from the University of Tasmania (Centre for Ore Deposit Research) and a PhD from Macquarie University.
