There's a lot more that needs to be done before Teck can sanction the project. The FEED must be done(probably a year), all environmental permits must be in place and contracts signed for power and roads. Then they go through project sanction where the Teck BOD must approve the $ 3 billion capital, sustaining contingency etc. budgets. With the stroke of a pen Teck gets 75% of the reserves wiithout essentially spending a penny, only a committment to spend $ 340 million. This apparent low cost to acquire actual reserves will look very good on their books and at bonus time. They will be motivated to close this deal.
