Copper and nickel reserves and resources held by Brazil's Vale Base Metals (VBM) rose in 2025, after increased exploration drilling.
Vale's copper reserves and resources rose by 6pc to 53mn t, while nickel reserves and resources rose by 13pc to 14mn t in 2025.
The company aims to increase its reserves and resources by more than 20pc by the end of 2027, as it tries to convert known ore into supply rather than pursue harder-to-permit greenfields.
Vale added new reserves last year at Bacaba in Brazil's Carajas district and widened resources across Sequeirinho, Mata, Cristalino and Paulo Afonso, building on its mine life expansion programme announced in February 2025.
Carajas is Vale's easiest site to add new copper tonnes, because of established infrastructure.
Fresh tonnes at the long-running Sudbury underground hub in Ontario and at Voisey's bay in Canada extended mine life and backed new underground studies. Sudbury hit its highest ore production since 2016last year.
Vale plans to nearly double copper output by 2035, the company said last month.
