The reason I didn’t give the answers that Aurifice did is that those two methods will not be used nor approved at the MStar site. Better to no put such ideas into lay peoples minds. Mercury no longer allowed and it is still high in the ricer and A1 had a leach plant and its dam burst into the river so no more of that allowed hence the nice paste backfill system (the big tanks) at MStar plant. I assume you noted the comment in a recent AUL release about the good relations with EPA on water treatment and release for instance. Ask yourselves why add that small comment - just another small tick for the site guys on a large potential issue managed.
(I might start calling myself The K2, you put in the $ and I will build the sentiment hey K) sorry guys private joke.
