An alternative way to look at the met. results are 95% recovery is 10% better than 85% from low grade deposits so we should sit 10% higher than those nomographs put up.
The other thing is a grind to say 80% passing 106 microns (relative to finer grinds of P80 of 75um or less) could save say 20% of the total energy cost of the mine as well.
