Cleveland was an underground tin and copper mine operated by Aberfoyle Limited between 1968 and 1986. During the life of the Cleveland operation, Aberfoyle mined and processed from the semi-massive sulphide orebody 5.7M tonnes of ore and produced approximately 24,000 tonnes of tin and 10,000 tonnes of copper in concentrate. The mine closed in 1986 due to a rapid decline in tin prices caused by the collapse of the International Tin Council. At the time, Aberfoyle was a major operator in the tin and tungsten mining industry with four operating mines in Australia.
Elementos has over 6.6Mt of Mineral Resources defined today. In addition, Elementos has defined, in a separate deposit, accessible from the same underground infrastructure, approximately 4Mt of porphyry hosted tungsten (WO3).
