An environmental organisation in New Caledonia says it's scandalous that the Goro Nickel plant is just about complete while key surveys have not been done yet.
The head of the group Together For The Planet has told a local radio station that studies have to be completed into the chemical plant used to produce nickel and the storage of the plant waste.
But a spokesperson for Goro Nickel says it's not too late to modify aspects of the project which is estimated to cost about 3.2 billion US dollars.
The ICPE operating licence for Goro Nickel was cancelled by a Noumea court last year and a new permit is yet to be issued.
Together For The Planet says it regrets that the company is about to be given the go-ahead when an application is pending for the New Caledonian lagoon to be made a Unesco World Heritage site.
