The New Caledonian Goro Nickel company says it is pleased with a French court of appeal decision that has thrown out a court injunction on part of its project.
The French appeal court has overturned a ruling by a Paris court in November last year that imposed an injunction on building the company's waste storage site.
It was issued after the Kanak activist group, Rheebu Nuu, claimed it would damage the environment.
Goro Nickel's spokesperson, Catherine Guillaume, says the ruling is no surprise.
"We are pleased about this decision as we will be able from now on to re-start the work on this area of the project. And we were expecting this decision and it is a very important decision for us."
Ms Guillaume says the company has resumed work at its waste storage site.
She adds it is not clear how much money and time Goro Nickel lost because of the injunction.
