Teck also now expects the unit mining cost of product sold to be in the range of $71/mt to $76/mt for the year primarily as a result of one-time costs related to labor settlements and higher than expected costs for items such as external mining contractors and diesel. Unit mining cost of product sold is expected to be higher than this range in the second quarter at approximately $80/mt to $84/mt and then trend downwards in the third and fourth quarters as coal volumes increase.

Teck expects average selling prices for the second quarter of 2011 to be approximately $270/mt compared to its existing guidance of $280/mt to $290/mt. This is due to changes in the sales mix related to the deferred shipments to Japan.
