Here are some questions I think Teck tries to answer in regards to SC.

Is SC profitable?

Are the profit margins of SC satisfactory in comparison to Teck's other assets?

How long will it take to build the mine?

How long will the payback be?

How long will the EA take?

Do we have a mine friendly government?

When is the next election?

Does Teck have enough cash and liquidity to put it into production?

Does Teck foresee higher copper demand in the future?

Depending on what Teck see in SC, their schedule is not that long. 2017 is provincial election. I would use this date as a guideline to how Teck wants to get a pemit asap. Which relates to the 99% problem. I don't think Teck has that much time to work with unless they want to risk going through permitting process with a different goverment say NDP?
