July 15, 2010 Teck Provides Additional Update on Greenhills Incident VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 15, 2010) - Teck Resources Limited (TSX: TCK.A and TCK.B, NYSE: TCK) ("Teck") reported that work continues at the Greenhills mine's coal dryer building. The investigation into the cause of the accident that occurred on June 28 continues with review of the data and evidence although no conclusion has been reached yet. The building has now been made safe for entry, and the mechanical inspection of the building has concluded that most of the exhaust side of the dryer system will need to be replaced. An engineering firm has been contracted and is on site as project manager for the rebuild, and they are currently establishing a scope of work and timeline for the rebuild. The current plan is to activate the bypass system around the dryer which will allow the company to produce and ship wet coal for blending with dry coal from other mines. Power is currently being established to the bypass system so the mechanical integrity and operational control of this system can be determined. Greenhills has been shipping raw coal to Fording River since July 2, 2010. The combined impacts of shipping raw coal from Greenhills to Fording for processing and shipping wet coal from Greenhills will significantly reduce the impact on production. At this point Teck does not have an update on production guidance for the year until the timing associated with the various steps is better defined.
