Kym Winter-Dewhirst

[4] Kym Winter-Dewhirst has had a long professional association with the Olympic Dam copper, gold and uranium mine near Roxby Downs in South Australia.

[5][6] In 2012, following the dismissal of Arabunna elder Kevin Buzzacott's legal challenge of the Olympic Dam mine expansion's environmental approval, Winter-Dewhirst told the ABC that the company had always been confident and welcomed the result.

[5] In his role as Vice-President External Affairs he briefed the Minister of BHP Billiton's intention to undertake heap leaching mineral processing trials at Olympic Dam.

Winter-Dewhirst told staff that a new Executive Committee (ExCo) would meet in February "with a focus on business planning, delivery measurement and reporting, as well as embedding our values.

[14] In 2016 Winter-Dewhirst told in Daily "I always felt that in this job time is my enemy… And so I decided I would make some significant changes and I would start at the top, and I would create opportunities for others to step up and seize a new agenda."

Winter-Dewhirst was also the Minerals Council of Australia's appointed representative on the Lake Eyre Basin Agreement's Community Advisory Committee.
