Hundreds of workers at the Solomon Islands gold miner, Gold Ridge Mining Limited, have been made redundant.
The Australian based company says in a statement more than 400 of its 570 strong Solomon Islands workforce have now lost their jobs.
The mine has not been operating since the beginning of April when flooding put it out of action.
The company has now also removed all its expatriate workers, citing security concerns.
It is the second time since the flooding that it has taken such action.
In a statement Gold Ridge says there have been a number of recent serious security incidents which have been growing in frequency and severity.
It says a strong police presence at the mine site is critical.
The company says it is in discussions with the Solomon Islands Government about the future of the mine and says it could sell out of the operation.
