They would need to have financing to actually build SC, not just buy us out.

Teck has classified this as a "cheaper rather than sooner" project. I suspect SC is likewise classified since that seems to be the Teck mantra.

They say they will be financing their share through a combination of cash balance, free cash flow over the four-year build period, and $2B of unused line of credit. That doesn't leave a lot of room around the edges.

Their first payment of around $880M is due at the beginning of 2015 (I think because they have already put some towards the project, not sure though.) Their total costs will be $2.94 billion over the four-year period. After 2017 though they start to have a good steady income.

It could be that Teck won't be buying us out after all, but that doesn't mean they won't improve the numbers of the project and help us find a buyer that they can live with.
