Ore production has commenced ahead of schedule at Xstrata Zinc's A$303m (US$296m) Lady Loretta mine in north-west Queensland, Australia. The early production, which accompanies ongoing development of the underground zinc-lead silver mine, is ahead of the original scheduled start date in mid-2013. Xstrata's decision to develop the upper ore bodies independently of the deeper underground resources will increase annual ore production at Lady Loretta from 1Mt to 1.2Mt. Ore from the mine will go through primary crushing on site before being transported to the Xstrata Zinc Mount Isa complex for processing.
