“This extension represents an important milestone in our partnership with Greatland and reinforces the strategic importance of Telfer to our business and reflects our proven track record of operational performance on site for over a decade,” he said.

“We are proud of the contribution our people have made over this period and look forward to supporting Greatland as it advances Telfer’s next phase of growth and value creation.

“We remain focused on delivering safe, reliable and productive outcomes while strengthening our collaboration with Greatland.”
