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.

Decrmber 31, 2022 - The Group continues to report the results of the Copper Bay entities within Discontinued Operations. These assets were fully written off in prior years.


Central Asia Metals PLC 75 % Indirect
Copper Bay Ltd. 100 % Direct
The Central Asia Metals owns a 76% stake in Copper Bay Limited, which is currently for sale. Copper Bay Limited owns 100% of the project at Chañaral Bay.

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.

  • Tailings


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 Chañaral 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 Chañaral, covering an area of 13km2.
