We used the same numbers as Galore.....from Teck AIF:

Galore Creek
Teck has a 50% interest in Galore Creek. The year-end 2018 resource statement presents a
conceptual change to the project. Only mineral resources are reported in 2018 and are estimated
based on commodity prices of US$3.00/lb copper, US$1,200/oz gold and US$20/oz silver.

Schaft Creek
Schaft Creek resources are based on a 2018 Resource Model Update. Open pit mineral
resources are reported at an NSR cut-off of US$4.31/t and constrained by a conceptual open pit
shape. The resource estimate categorizes 10% of the mineral resources as Measured, 70% as
Indicated and 20% as Inferred.
