Rosebery is 100% owned by CMM Limited and has been operating continually for over 85 years, with operations starting in 1936.Zinc, copper and lead concentrates, as well as gold doré, are produced at Rosebery using mechanised underground mining method followed by crushing, grinding and floatation processes.
