There's been quite a bit of talk about grade factoring...... it's certainly a big factor in the Vic gold sphere.... Just on the metallurgy tests and what the famous Opaline has been talking about........ I think the company made it fairly clear what their results were from the first three large samples....... I'm not in front of the release but I recall they did tests over 4 different crush sizes.. (I think around 100 microns to around 350 or 400 microns)...... At 250 microns it was shown in all samples the 'free milling gold' (not a term i'm overly familiar with) was 88%.....I think at smaller crush size of 150 mic (IE finer) it was 93% and was higher again at 100 microns which makes sense..........This was all without any nasty chemical treatments.... just crushing and water.... not bad!!!!
