Before agreeing to allow CUU to proceed with the PEA both parties would have reviewed the consequences of a range of outcomes. Right now Teck lists SC as having the least amount of investment return potential among the 5 satellite projects. A substantial improvement in the NPV/IRR means they have to decide how to characterize the SC project publically. It's not just an awkward situation for Teck, they would need to look at revising both future spending and where the project fits in the Long Range Plan. None of this is a problem for Copper Fox, who need the updated economics to put out the for sale sign. Their risk is spending the money on the PEA and the results are still not good enough for Teck to change their view of the project, which currently stands as early stage,small budgets and no development plan. Once the results are released then we can compare to the Zafranal and San Nicolas IRR/NPV numbers to see where SC ranks now. The 2013 FS numbers were post tax 8% and $ 67 million CDN.
