Not an expert but do have chem background !
As I understand it (and may be wrong ) more oxidised ore would tend to knock some of the cyanide out of solution when extracting gold but from what I'm reading this seems to be sulphide ore so maybe Co may not be a problem here when extracting gold .
Just how ameanable the gold is to treatment is yet to be established .
