Lennard Shelf Operation Ceases Production

VANCOUVER, BRITISH COLUMBIA AND MADRID, SPAIN--(Marketwire - July 14, 2008) - Teck Cominco Limited (TSX: TCK.A and TCK.B, NYSE:TCK) and Xstrata Zinc today announce the closure of the joint venture Lennard Shelf Pillara mine in Western Australia. Operations are expected to cease by early August.

The Pillara mine has become uneconomic, primarily due to the sharp decline in zinc and lead prices compounded by the appreciation in the Australian dollar. Higher energy and labour costs and lower than planned production have also contributed to rendering the project uneconomic. The decision to start Lennard Shelf was made in 2006 and production commenced in early 2007. In the period to 31 December 2007, the operation produced 42,100 tonnes of zinc metal and 12,400 tonnes of lead metal.

Orderly mining of drilled and broken ore stocks will be undertaken from today until the cessation of milling operations. Mine development and exploration work has been suspended. All existing contracts will be terminated and employees will be provided with appropriate support.

Dewatering of the Pillara mine will be discontinued following de-commissioning and the plant and surface facilities will be placed on care and maintenance until a decision on the long term future of the assets and tenements is taken.

The closure is not expected to have a material impact on earnings for either company.
