Nickel producers in New Caledonia have suffered setbacks amid this week's massive stock market decline in China.
New Caledonian media have collated figures, showing that the key stake holders lost up to 5.3 percent of their share value.
The companies, Eramet, Glencore and Vale, have huge investments in nickel plants but all operated at a loss last year estimated to total about one billion US dollars.
The price of nickel on the London market however has seen a modest rise after last year's huge slump.
