RE: Hydro costsBased on recent past power usage I can approximate the power cost as follows:
Power Cost (MM$/period) = 5.3 X copper production(MMLbs) X Power Costs($/KWH)
For example for the most recent quarter: 5.3*13.3*0.17= $12MM.
Just a ballpark calc. using historical power usage of 5.3 KWH/ LB Cu.
