Think about this as well in regards to buying producing copper assets.

If Teck was a buyer in the market, they would want to buy good copper assets right?

Well, who will sell them is the question? Unless it's a takeover, producers would only want to sell their not so pretty producing mines to reduce their debt level. So it goes back to the question of are the assets out in the market place significant better than the assets Teck has in their own pipeline? Yes assets out there can be paying me back today but are the economics and jurisdiction matches with Teck's long term goal?

I don't think it's as easy to look into what Teck is going to do.
