Inata Production Update

Inata Production Update

Avocet Mining PLC ('Avocet' or the 'Company') today announces updated full year 2013 guidance for the Inata Gold Mine of 125,000 to 130,000 ounces, reduced from previous guidance of 135,000 ounces.

This update follows production during the third quarter of 30,987 ounces, which was below expectations due to lower than planned grades and mill availability. The lower grades in the third quarter partly reflected reduced availability of the mobile fleet, which caused delays in waste stripping to access higher grade ore. The updated guidance for the year also takes into account the impact of these issues on the fourth quarter. The reduced production means that cash costs per ounce in the second half of 2013 are likely to be similar to those in the first half of the year.

The Company will provide a Tri-K feasibility study update on 11 October 2013, and will release its full operational and financial results for the third quarter on 31 October 2013.
