Turquoise Hill Resources Ltd. (“Turquoise Hill”) today announced the appointment of Jo-Anne Dudley as Chief Operating Officer, effective June 3rd, 2019.
Ms. Dudley has 25 years of experience in the mining industry. For the past nine years she has been a key member of the
Oyu Tolgoi technical team that manages the development of the world-scale Oyu Tolgoi copper-gold mine in Mongolia in
consultation with Turquoise Hill. Most recently she led Oyu Tolgoi’s 30-person Strategic Mine and Resources Planning
unit.
“Jo-Anne’s extensive experience in underground mine development, at Oyu Tolgoi and elsewhere, will be of great value to Turquoise Hill and its shareholders,” said Ulf Quellmann, Chief Executive Officer. “She will be an excellent addition to our executive team as Oyu Tolgoi grows into one of the world’s largest copper mines.”
Prior to commencing her work on Oyu Tolgoi, Ms. Dudley spent five years working with Rio Tinto’s technical group on
mines in South Africa and the USA. Before that she worked in underground mines across Australia as an Underground
contractor and spent nearly ten years in Operations and Studies roles at the Northparkes copper and gold mine in central New South Wales, Australia. During her time at Northparkes, it developed from an open pit operation to an underground mine using block caving, similar to the development path at Oyu Tolgoi.
Ms. Dudley graduated from the University of New South Wales as a mining engineer in 1994. She holds a New South
Wales Below Ground Mine Manager’s Certificate of Competency, and a Graduate Certificate in Technology Management.
A Chartered Professional engineer, Ms. Dudley was awarded Fellow membership in 2016 from the Australasian Institute
of Mining and Metallurgy, was selected as the 2018 Exceptional Woman in Queensland Resources, and was also honoured to be named as one of the WIM 2018 Global 100 Inspirational Women in Mining.
