Q4 2015 Inata Production

Avocet Mining PLC ("Avocet" or "the Company") today announces production and cash costs for the fourth quarter of 2015 at the Inata Gold Mine.

· Gold production for Q4 was 17,380 ounces at a cash cost of US$1,094 per ounce, compared with 17,517 ounces produced in Q3 at a cash cost of US$1,107 per ounce

· Full year gold production for 2015 was 74,755 ounces at a cash cost of US$1,058 per ounce, compared with 86,037 ounces in 2014 at a cash cost of US$1,186 per ounce

In spite of production challenges and cash constraints, safety continues to be a key result area for management. At year end, the mine had achieved 823 days (approximately 6.8 million man hours) since the last Lost Time Injury (LTI).

Mining and processing in the quarter focussed on lower grade, softer oxide ores, with head grades of 1.22 g/t and average recovery levels of 89%, compared with 1.50 g/t at 72% in Q3. Throughput increased to 508k tonnes from 448k tonnes in Q3, in spite of disruption caused by supply issues in the wake of the September attempted military coup.

Average mining costs of US$318 per ounce in 2015 were lower than the 2014 level of US$422 per ounce, despite the stripping ratio more than doubling from 4.5 to 9.8. This has been achieved principally as a result of the waste from the final North Pit pushback being dumped within worked out adjacent pits. The high grade carbonaceous ore from North pit is planned to be mined later in 2016.

The mine continues to seek further areas for cost reductions, and during the quarter all management salaries were reduced by 10%. In spite of a decrease in cash costs in the quarter, margins remain tight in the context of gold spot rates and particularly diesel prices, which have been held at March 2015 levels. The Company continues to work with the Chamber of Mines to lobby the Burkina Faso government to reduce the price of fuel to reflect the fall in global oil prices.

Further details of Q4 2015 production are set out at Appendix I.
