But in 2013, the Xstrata-owned Brunswick and Perseverance mines in Canada will run dry, removing about half a million tonnes of zinc from the global system.

"We are trying to make that up with expansion in ore mines," Emilio Tamargo, general manager for business development and research at Xstrata's zinc unit, told Reuters on the sidelines of a conference organised by Metal Bulletin.

"I think total capacity we are working on is about half a million tonnes which more or less will compensate what we are losing," Tamargo said.

Xstrata expects to complete expansion of its Mount Isa mining operations and start up Lady Loretta mine in Australia next year, he said.

Lady Loretta is expected to have an annual production of 126,000 tonnes, according to Xstrata website.
