The leader of New Caledonia's Rheebu Nuu environmentalist group says its demand for a stop to the Goro Nickel project by September 24th still stands.

Mr Mapou says the construction of the plant is moving ahead too quickly because it will take another two years for the findings to be validated.
The project is to be completed next year and it is the largest enterprise in the region, currently employing about 2,000 people, among them hundreds of Filipinos.
In April, Rheebu Nuu activists vandalised the Goro site, causing 10 million US dollars worth of damage and stopping all work there for about three weeks.
The group says unless construction is suspended by September the 24th, there will further action.
