The key infrastructure elements are in place.
- Production of copper concentrates have been successfully completed and commissioned.
- The pre-stripping process at the mine pit was completed in April 2014, with a total of 192 million tons of material removed.
- At the plant site the key processes such as crushing, grinding and flotation plants were successfully launched.
- A 143-kilometre coastal pipeline is operational that fills a pond with 750,000 metres of seawater.
The mine’s opening ceremony is planned this autumn.
