Mine Life9 years (as of Jan 1, 2015)
After 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.

June 30, 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.

Deposit Type

  • Tailings


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 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.


Mining Methods

  • Dredging


Summary:

Currently, it is envisaged that the resource will be mined using dredging operations feeding the tailings product to the process plant.
