Energy Resources Australia (ERA) has restarted processing operations at its Ranger mine today.
This signals the end of a suspension on plant processing operations at the mine as a precautionary measure to ensure levels in its tailings dam remained below the maximum limit during the wet seasons.
The miner extended its self imposed suspension on 12 April until late July to allow for process water levels to reduce.
ERA expects that it will take around a month for the processing plant to return to normal production levels.
It has revised its 2011 first half loss guidance to between $20 million and $30 million, up from a previous forecast of $30 million to $50 million.
