Stratmin plots course for global graphite status, page-36

I think you are right about the KNL opex costs being a concern for investors. The other thing that worries me is the much higher basket price as well.

SYR are already connected to the grid. They included diesel power generation into their FS because it is high risk that grid power has black outs and other reliability problems. I don't know what ratio of grid v generator power the consultant used for opex costs, but the whole capex cost would have been included.

Besides having ore from surface, SYR have a low strip ratio because they have a cut off for the Resource Statement of 3% TGC. However, their Reserve Statement has a cut off of 9%. All that stuff that is dug from the blocks or levels below the 9% cutoff is being stock piled and called "low economic value". That explains the low strip ratio.

Can't comment much about the difference in rock types, ore hardness, weathering, softness of digging etc as can't remember those details from the top of my head.

Cheers
