Magellan Mines has been given the greenlight to recommence lead shipments from its Wiluna mine.
Wiluna came under increased scrutiny following a series of lead contamination scares along its rail line and port berth, after traces of lead were found in dried mud on the outside of the shipping containers holding the sealed bags and lead was transported along undeclared rail lines.
Ivernia, the owner of Magellan, welcomed the approvals, and will also undertake its own review and assessment to "fully understand their impact on its mining, processing, transportation, and export activities".
The approvals will allow Magellan to ship lead carbonate concentrate from its Wiluna mine for a five year period.
However, before it can do so it must complete an environmental management program; a third party evaluation of the company's sampling and analysis methodologies; and an environmental risk assessment.
Magellan chairman Wayne Richardson said "while a number of factors still need to be considered before making a decision to restart, we do not anticipate re-commencing any shipments prior to the second quarter of 2013.
"It is important to emphasise again that during the past 18 months multiple internal and external reviews into all aspects of our operations have made it clear that there has been no risk to the general public or our employees from the production and transport of our concentrate since the commencement of shipments in bags and sealed containers in 2009," he added.
