Update on Inata

Avocet Mining PLC, ("Avocet" or "the Company"), the West African focused gold mining and exploration company, provides an update on the progress of the Tri-K transaction and an update on Inata.

Progress of Tri-K transaction with Managem

Avocet has received the Presidential Decree which ratifies the Mining Convention for Tri-K project as an Act of law. "First Closing", whereby the Company will receive $4 million from Managem for 40% of its interest in project is expected to happen on short notice. A further announcement will be made at this point.

Update on Inata

As announced earlier, in the past weeks, the new management has started discussions with the trade creditors, banks and government to stabilize SMB and with a view to restructure its debts. This will represent a considerable challenge, with compromises needed from all stakeholders.

It is against the background of these ongoing discussions that the mine is experiencing shortage of certain critical supplies, causing stoppages in parts of the mine's production processes. In order to lower its fixed costs during such stoppages and to provide the operational flexibility to react to the changing availability of supplies, the majority of its workers have been put in technical unemployment for a period of three months.
