One thing Don Lindsay always says is that he looks at projects that are in the lower half or better on the cost curve.

SC has a cash cost of about $1.15 per pound inclusive of by-product credits.

Teck's cash costs are expected to be between $1.70 and $1.90 this year for copper.

The industry median price is $1.58 for 2013.

Schaft Creek is way under the median price and would probably be even better if you take into account the falling Canadian dollar and if any significant amount of that waste rock could be converted to reserves.

I think our biggest problem in terms of cash costs is the opex seems very high. I'm not sure what Teck could do to improve those costs.
