Working for one of the biggest public companies in the world, headcount and allocating ressources is a big issue.  Teck's focus was QB2 for years and after that, they allocated a team for Schaft Creek.  That's great news in my opinion.

After, in order to move projects ahead, you need to build a solid business case to justify the investment to shareholders.  With a NPV (8%) of 513M, you don't go very far.  It's my understanding that fine tunning takes a long time, but if they are putting this effort now and for me, that's also great news.

Resource/Copper sector has been awfull for the last decade.  To move a projet ahead, you need money.  Teck now has money to invest, so that's again great news.

Finally, look at what happened with Rosemont.  They didn't make things right the first time and now got put on hold by a judge.
