mineral reserve and mineral resource estimates for Teck Cominco Limited's
material properties, other than Antamina, Elkview, Fording River, Greenhills,
Coal Mountain, Line Creek and Cardinal River (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
