Capital expenditure included decline and mine level development, ventilation infrastructure and various minor works in the processing plant.
The September-December 2012 quarter was the first full quarter of production at the Outokumpu project.
Looking ahead to the March 2013 quarter, the company expects the expenditure to remain in the $3-4m region, towards continued decline and level development for the mine.
Altona clarified that the A$7.7m item in the earlier released Quarterly Report was made in accordance to the Australian Accounting Standards to match the disclosure required by the Australian Stock Exchange.
