Atalaya Mining said copper grades, recoveries and operating cash costs in the year-to-date were with in line forecast values.

The company also stuck to its estimated copper production guidance for 2018 of 37,000 to 40,000 tonnes.

An expansion project to add 15m tonnes of throughput per year was launched at the beginning of December 2017.

A process flow-sheet, basic design criteria and preliminary layouts had been established, Atalaya said.

Financing to initiate the expansion was raised through a £31m placing of new shares, allowing long-lead equipment to be identified and purchase orders issued according to schedule.

The expansion was on track to deliver the increased production by 2019, the company added.
