TECK COMINCO LIMITED (Registrant) Date: October 5, 2004 By: /s/ Karen L. Dunfee ------------------------ Karen L. Dunfee Corporate Secretary [GRAPHIC OMITTED] [LOGO - TECKCOMINCO] ------------------------------------------ For Immediate Release: October 4, 2004 TECK COMINCO LIMITED ANNOUNCES DRILLING RESULTS FROM ZAFRANAL COPPER PROPERTY IN SOUTHERN PERU Vancouver, B.C. -- Teck Cominco Limited announces drilling results at its 100% owned Zafranal copper exploration project in southern Peru. The Zafranal property is located in the Paleocene Copper Belt of southern Peru, roughly 100 kilometers northwest of the city of Arequipa. The elevation of the property ranges from approximately 2500 to 2900 meters. The Zafranal property was staked as part of a 2003 reconnaissance program targeted at porphyry copper deposits in southern Peru. Through a wholly-owned subsidiary, Teck Cominco holds or is being granted mining concessions covering approximately 39,000 hectares in the area of interest. Initial prospecting, mapping, and sampling in 2003 and 2004 outlined an area of approximately 2.5 kilometers by 1.0 kilometers of surface mineralization and alteration typical of a porphyry copper system. The main zone, untested by previous exploration, shows copper oxide mineralization on surface, a phyllic alteration zone, a hematite-rich "leached cap" and quartz-limonite stockwork development. Final analytical results have now been received for a 12 hole reverse circulation drill program totalling 3,689 meters. A map showing drill hole locations and a table of assay results for mineralized intersections are attached . Highlights include the results for holes 7, 8, 9, and 10: an east-west alignment of holes, all drilled at minus 65 degrees to the south, which cover more than one kilometer in strike length of the mineralized trend.

Drill results are consistent with a mineralized blanket, 150 to 250 meters thick which dips parallel to the current slope orientation. Mineralization remains open along trend and down dip. Initial microscopic analysis of drill chips indicates the main copper minerals to be chalcopyrite rimmed by chalcocite and minor covellite. Ore characterization and metallurgical testwork, including soluble copper and flotation tests, will continue with ongoing exploration. Holes 007-010 represent only one line of drilling. A second drill program is in progress on the property, which involves an additional 3200 meters of reverse circulation and 1600 meters of diamond core drilling. Drilling will test areas along trend from holes 007-010 as well as down dip and at depth from the higher grade holes. Additional project information will be released as drilling is completed and analyses have been received. Chips from the reverse circulation drilling are split at the drill site for each 2 meter interval. A 2 to 3 kilogram sample intended to be representative of each 2 meter interval is sent to ALS Chemex facilities in Lima where a 250 gram sub-sample is prepared. A portion of the sub-samples are shipped to ALS Chemex in Vancouver for analyses. Gold analysis is by 30 gram fire assay with an atomic absorption finish. Copper analysis is by aqua regia acid digestion and ICP-AES. Total copper analyses by multi-acid digestion and atomic absorption finish was completed by Teck Cominco's Global Discovery Labs in Vancouver on the same samples prepared and shipped by ALS Chemex. QA/QC, including the use of sample standards, blanks and duplicates as well as chain of custody is monitored by Teck Cominco. Mr. Steve Jensen P. Geo, Teck Cominco's Manager of Exploration for Peru, is the Qualified Person as defined by NI 43-101 for the project, and has verified the information contained in this release. The Zafranal property is located in Peru. Mineral exploration and mining activities in Peru may be affected by changes in political or national economic conditions beyond the control of Teck Cominco. Further exploration and possible development of Zafranal will require various environmental and other permits and government authorizations. Permitting requirements or environmental regulations could have a material adverse impact on further exploration or development of the Zafranal property. There is no assurance that further exploration of the Zafranal property will result in the discovery of minerals in sufficient quantity or with adequate grade to justify development of the property. -3- Teck Cominco is a diversified mining company, headquartered in Vancouver, Canada with assets totalling approximately $5.5 billion.
