The Antas mine is an iron-oxide-copper-gold (IOCG) style deposit located in the Carajas region of Para State in northern Brazil. The deposit was discovered by Avanco Resources in 2011, construction commenced in 2015 and was completed in under 12 months. In July 2018, Oz Minerals closed a deal to takeover Avanco Resources in a A$418 million (US$320 million) deal comprised of cash and Oz Minerals shares. In 2019, Oz Minerals announced plans for the Antas process facilities to form the hub for the Carajas region, with production from the Pedra Branca underground mine to be processed through the Antas mill. In May 2023, BHP completed the acquisition of OZ Minerals, thereby gaining ownership of the Antas operation.
