some basics - sdl vs. fmg, page-23

In addition to the CAPEX per tonne per year, i don't think the "per year" part is necessary as this cost has nothing to do with a per year basis.

I am still quite confused what this figure actually does, why is it in the graph? Of what importance is it to the project?

Does it simply show for each input of CAPEX dollars ($96 in this case) it will give the ability to produce 1 tonne a year.

Where as FMG had a lower figure as their CAPEX was lower and tpa was higher.

So to make that figure clear the CAPEX per tonne per year is actually:
Amount of CAPEX associated for the ability to produce 1 tonne every year. Every $94 of CAPEX SDL spend will allow it to produce 1tpa.

That makes more sense, i actually came up with the explanation while typing but im now satisfied with what the figure means.
