    As soon as you start picking out nuggets, black minerals or whatever else the sample becomes bias and represents nothing more than the presence of the minerals assayed for. As soon as a sample has a bias the grade become irrelevant and should not be reported as such. For internal company purposes as a targeting tool then fine, but to report as grade in the highlights of an ASX announcement then I am sorry it just doesn't pass muster for me.
