Avocet Inata gold drilling results support further mine expansion

Avocet Mining PLC (“Avocet” or “the Company”) has received the latest results from its drilling programme at its flagship Inata gold mine in Burkina Faso. The drilling programme was conducted over the first half of 2011 within the Company’s existing mine license area. Highlights of these results are:

• Extensive drilling along the projected north-south trend of the Inata strike, continues to intersect significant gold mineralization at potentially economic depths
• High grade intercepts (3.4m at 10.6 g/t Au and 5.5m at 6.35 g/t Au) and wide intercepts of medium grade (45 m @ 3.26 g/t Au and 44.6 m @ 3.73 g/t Au) occur over six kilometres of strike
• Continuing trend of strong drill results supports plan for mine expansion in 2012 to apx. 245,000 oz. capacity for FY2013 production
• Sufficient drill results now received to complete Mineral Resource update, which will significantly contribute towards the Company’s intended target of doubling reserves at Inata to 1.8 M oz.
• Mineral Reserve update on track for release at the end of Q3 2011
