SYDNEY, Feb. 3 -- Zinc concentrate production has resumed at Australia's Century zinc mine after being suspended last week due to a tropical storm, the mine's owner, Minmetals said on Wednesday.

Ore mining was not interrupted but concentrate output stopped on Jan 26 as the storm threatened the port of Karumba where the material is loaded on ships for export to smelters.

The Century mine is the world's second largest of its kind and produces about 500,000 tonnes of zinc, a third of Australia's total production, from 1 million tonnes of concentrate annually.
