Under the deal, Accenture will offer end-to-end sourcing and procurement services, in addition to bringing category expertise, cloud-based sourcing, category-management and procure-to-pay tools.

The contract is said to deliver cost savings of around $300m over the next six years to Glencore.

Glencore Mount Isa Mines central services general manager Trevor Gray said: "We are continuously reviewing opportunities to improve our global competitiveness and long-term sustainability."

The company will also provide market sourcing insights and analytics to help Glencore to increase its procurement and sourcing benefits.

Accenture resources managing director Joost Van De Meent said: "Mining clients continue to grapple with cost pressure in the ongoing environment of low commodity prices."

"Our solution will extend Glencore’s existing procurement capability to improve spend management and reduce transaction costs, while improving visibility across Glencore’s businesses."
