With all due respect Golf, I think you need to read the entire section 21.2 Operating Cost Estimate from the January 23, 2014 feasibility study on Schaft Creek. The $231M figure that you use to arrive at your conclusion that it represents 43% of total operating costs is incorrect. $231M is the average mill (mineral processing) operating cost. Nothing to do with the mining costs. Mill opex is 36% of total opex while mining opex is 50%. The remaining 14% is made up of misc. costs. Using these numbers we can arrive at total annual operating cost of about $642M. If fuel costs are $101M the fuel would represent about 16% of total operating costs. Still a very significant cost. I stand to be corrected but that's my take.
