Here are some details of Red Chris connecting to the line. Imperial Metals could pay up to $80M for constructing the connection line to their mine. Plus a "special tariff" will be required by BC Hydro. So all eyes on Hydro this year.

B.C. finalized the terms -- see the terms here -- of the Iskut extension in late March: the owners of the Red Chris mine, Vancouver-based Imperial Metals, will build the Iskut extension itself and sell the completed line back to BC Hydro. The terms call for Imperial to pay any costs over $52 million, which means the miners should pay at least $80 million to get grid power for their mine. (Imperial Metals Exploration Manager Steve Robertson confirmed that Imperial will be on the hook for any cost overruns.)

Whether Imperial Metals will be able to raise the estimated $500 million needed to build Red Chris -- in a jittery global economic climate where long-term debt financing has all but dried up -- remains to be seen. Robertson says the company is confident it can complete its financing by June of this year.
