From the late 80’s and through the 90’s, lead and zinc were exported through the Port and there are still some areas of marsh adjacent to the Port area where elevated levels of these metals are detected during the routine monitoring undertaken by CGLtd.

The export of nickel from the Port to China commenced in 2004. A process of continuous review of storage and loading procedures has resulted in significant improvements in the environmental performance of the operation.

The shed that which was originally used for nickel concentrate storage was constructed for cotton storage and was also used for storage of lead and zinc, was inadequate in its design and construction for the storage of ore concentrate. A new purpose built was constructed by Panoramic Resources on CGL's adjacent freehold property and export of concentrate commenced from this facility in July 2012.

This was an important aspect of the transition from the port's original concentrate storage and loading operation to a system that is arguably the most environmentally responsible and cost effective arrangement of any port in Australia.

The old nickel shed has been cleaned and remeidated and is now used for the sorage and plant and equipment. In consultation with the Department of Environmental Regulation a process has been initiated to idnetify any contamination issues within the Port and adjacent marsh land and develop an appropriate remediation strategy to address these.
