Avocet Mining PLC ("Avocet" or the "Company") announces that the Company received and accepted the resignation of Brett Richards, Chief Executive Officer on 18 July 2012. Brett will stand down as Chief Executive Officer and as a director of the Company with immediate effect.

David Cather, who joined the Company as Chief Operating Officer in May 2012, has been appointed Chief Executive Officer and it is the intention of the Board to appoint David as an Executive Director at its next meeting.

David is an experienced mining engineer with over 30 years of experience in building and developing mines, most recently in his role as the Chief Operating Officer of European Goldfields.

His career has included senior roles at Anglo American where he was Technical Director for its Industrial Minerals Division, Redland Aggregates Ltd. (now Lafarge SA) and De Beers.

Avocet remains committed to the development of its Inata Gold Mine in Burkina Faso and to maximising value from its gold projects in Guinea. To this end the Board considers that David's experience will be invaluable in realising the considerable potential of the Inata mine and the surrounding Bélahouro area. Overall these management changes will enable Avocet to further its objective of becoming a leading West African gold mining and exploration company.

Russell Edey, Avocet's Chairman, commented:

"Over the last two years Brett has played a central role in transforming Avocet from a South East Asian mining company to an established West African gold mining and exploration company. The Board would like to thank him for these contributions and wish him every success going forward. As the Company enters its next phase of development, ensuring operational success at Inata will be critical to underpinning Avocet's continued growth. David's strong operational focus will lead the experienced on-site management team to ensure delivery on this growth strategy."
