Announcement of Chief Executive Officer Succession

Avocet Mining PLC ("Avocet" or "the Company") announces that Jonathan Henry has tendered his resignation as Chief Executive Officer and from the Board of the Company effective 31 May 2010, in order to pursue other interests.

Jonathan has been with the Company since 1994, in a variety of senior management capacities including Finance Director and has been the Chief Executive Officer of the Company since 2006. He will remain with the Company to facilitate an effective hand over of the management of the business and will provide on-going support to the Board.

Effective 1 June 2010, Brett Richards will be appointed the Interim Chief Executive Officer of the Company, and will work with Jonathan on a hand over of day to day business activities of the Company during May. Thereafter Jonathan will provide consultancy services to the Company to ensure a smooth transition of the business and the successful completion of the listing application to admit the Company's shares to trading on the Oslo Stock Exchange.

Brett has been working with Avocet in the capacity of Executive Vice President, Corporate Affairs since June 2009, and has held various senior management positions in a variety of mining and metals companies over a 25 year career. Most recently Brett was a senior vice-president of Katanga Mining Limited from 2005 to 2009, and prior to that was in senior management roles at Kinross Gold and Co-Steel Inc., both in Toronto. Brett is a graduate in Mechanical Engineering Technology and has an Executive MBA from the Johnson School of Business at Cornell University, New York.

The Board of Avocet is reviewing a number of candidates for the Chief Executive Officer role and will be making an announcement in the forthcoming months confirming the permanent replacement for Jonathan.

Jonathan Henry, outgoing Chief Executive Officer commented:

"Avocet has entered its next phase of growth and development with the integration of its newly acquired assets in West Africa. The commissioning and ramp up at the Inata gold mine in Burkina Faso continues to progress ahead of schedule. I feel it is time to step aside and allow a new leadership to build on the recent successes, and facilitate the corporate strategy to grow Avocet into a mid tier gold mining and exploration company."

Nigel McNair Scott, Chairman, commented:

"Jonathan has led Avocet through a significant stage of growth since being appointed Chief Executive Officer in 2006 with the successful disposal of our Tajikistan interests in 2007; the expansion of our Indonesian interests; the move into Africa through the acquisition of Wega Mining in 2009; and successful merger integration, construction, commissioning and ramp up at Inata. He has established a quality executive leadership team, and the business is well positioned for his succession at this time. On behalf of the Board of Directors of Avocet, I would like to thank Jonathan for his long dedicated service and commitment to the Company, and for his leadership that has Avocet well positioned to execute its strategic growth plan.
