Perenti Limited says its underground mining subsidiary, Barminco, has signed a new contract to continue underground mining operations at the Agnew gold mine, in Western Australia, for Gold Fields Limited.

Agnew is near Leinster, and includes multiple underground operations. It has a life-of-mine of five years, according to Gold Fields’ website.
Barminco has been providing underground mining services at Agnew since 2010 and employs over 300 people across the site.
As part of this renewal, development and production undertaken by Barminco has been agreed for another three years (starting January 1, 2025), plus a one-year extension option. The contract value is around A$500 million ($321 million), with Barminco set to carry out underground development, production and related mining services.
Mark Norwell, Managing Director & Chief Executive Officer of Perenti, said: “We are very pleased to be extending our relationship with Gold Fields at the Agnew gold mine. Gold Fields is one of our most long-standing and valued clients, with a history of more than 30 years working alongside the various Perenti businesses. Our Australian operations are important for Barminco to deliver enduring value and certainty for our clients and shareholders.
“Maintaining long-term contracts with high-calibre clients such as Gold Fields supports continued delivery of reliable earnings for the business.”
Gabrielle Iwanow, President of Contract Mining at Perenti, added: “Barminco has successfully ramped up development and production at Agnew in recent years. We very much value the relationship with Gold Fields and we look forward to continuing to deliver safe and productive underground services through our highly capable team in Australia.”
