Dear Sirs:

            Re: Teck Cominco Limited Registration Statement

            Consent of Expert

            In connection  with the offer by Teck Cominco Limited of its Class
B Subordinate  Voting Shares (the "Offer"),  I hereby consent to the use of my
name in connection with references to my involvement in the preparation of the
mineral reserve and mineral resource  estimates for Antamina (the "Estimates")
and to the  use  of the  Estimates,  or  portions  thereof,  in the  following
instances,  each of which is incorporated  by reference into the  registration
statement  on Form F-10 of Teck  Cominco  Limited  relating  to the Offer (the
"Registration Statement"):

            (a) In Teck Cominco Limited's Annual  Information Form dated March
1, 2006 (the "AIF") under the heading "MINERAL RESERVES AND RESOURCES--Mineral
Reserves at December 31, 2005";

            (b)  In  the  AIF  under  the  heading   "MINERAL   RESERVES   AND
RESOURCES--Mineral Resources at December 31, 2005"; and

            (c) In the Offer to Purchase and Circular  dated May 23, 2006,  as
amended by the Notices of Variation and Extension  dated July 24 and August 3,
2006 (the "Offer to Purchase").

            I have read the Offer to Purchase and the  Registration  Statement
of Teck  Cominco  Limited  and have no reason to  believe  that  there are any
misrepresentations  in the information contained therein that are derived from
the  Estimates or that are within my knowledge as a result of the  preparation
of the Estimates.

                                        Yours truly,


                                        /s/ Dan Gurtler
