Atalaya fine tunes copper guidance on record Q3 output

Record third-quarter production from the Proyecto Riotinto mine, in Andalucía, Spain, has prompted Atalaya Mining to fine tune its copper production guidance for 2017. The mine boosted its September-quarter production by 18% to a record 10 679 t of copper in concentrate, as copper head grade and recovery rates exceeded expectations. The operation reported an average copper head grade of 0.58%, a throughput of 2.2-million tonnes of ore processed and a recovery rate of 85.95%.
