SnapshotAfter announcing the positive results from the Copper Bay definitive feasibility study in January 2017, Central Asia Metals Pls (CAML) undertook some additional engineering studies with the intention of improving the economics of the Copper Bay project. While some capital expenditure savings were identified and there is the potential to optimise the project further in the future, the Board decided that these findings were not sufficiently material to warrant developing Copper Bay in the near term. In August 2017, the CAML Board therefore made the decision to sell the project.

The assets and liabilities of the Copper Bay entities continue to be presented as held for sale in the statement of financial position. The exploration assets and property, plant and equipment held in Copper Bay were fully written off in prior periods.

Summary:

Between 1938 and 1975 the Potrerillos and later the El Salvador copper mines, disposed of tailings from their respective mineral processing operations into the Rio Salado which outflows into ChaƱaral Bay. Over that period, it is believed that some 250Mt of tailings were discharged into the bay. These tailings now sit in the bay and on the beach at ChaƱaral, covering an area of 13km2.
