Expiry of the Standstill Agreement

Avocet Mining PLC, ('the Company') announces today that the standstill agreement between its subsidiary Société des Mines de Bélahouro SA ('SMB') that operates the Inata gold mine in Burkina Faso and certain of SMB's financial and trade creditors (the 'Major Creditors') has expired.

The Major Creditors amongst themselves could not agree on an extension of the standstill agreement to further concrete strategic options at hand.

Given the current status of discussions, it is unclear whether agreement on a restructuring of the balance sheet can be reached before SMB has exhausted all available sources of financing.

In light of the current circumstances, the boards of both Avocet and SMB will convene on 8 September 2017 to assess the status of the discussions with the Major Creditors, SMB's current liquidity position and its imminent liabilities. The boards will consider all available options, including the potential filing of an insolvency petition by SMB. No decision regarding whether or not to file for insolvency has been made at this time.
