Orvana Minerals said its Bolivian subsidiary Empresa Minera Paitití S.A. has produced its first copper cathodes from oxide stockpiles at the Don Mario site. The milestone follows the first gold-silver doré bar announced on September 8 and means both recovery circuits of the Oxides Stockpile Project are now producing finished metal. Orvana said ramp-up has been slower than anticipated and withdrew EMIPA’s fiscal 2026 production guidance. Management is focusing on mechanical reliability, operational stability, higher throughput and cost control, targeting an average processing rate of approximately 1,700 tonnes per day and planning another operational update for mid-October 2026.
