Goro Nickel's director general, Ron Renton, says Rheebu Nuu and Caugern are not above the law and have to obey the rules of the country.
This comes after a court in New Caledonia has ruled against them and has ordered them to pay 10 000 US dollars for damage caused during a protest against the company in 2004.
This comes in an ongoing dispute between the two sides over environmental aspects of the project.
Mr Renton says it is not OK for people to burn equipment.
"If people burn our equipment then we believe that they should be resp for those actions. Clearly our believe is that we are committed to respecting all the laws of the country. And we would anticipate that if we are op in a country where there is a rule of law then other people would that as well. And we would believe if people don't do that then there would be legal consequences for their illegal actions."
Goro Nickel's Ron Renton says he hopes the court ruling will not damage the current negotiations with Rheebu Nuu and Caugern.
Roundtable talks between the Southern Province, Rheebu Nuu, Caugern and Goro Nickel are under way and are expected to continue.
