I am not a great fan of this rns, the data is great, but why not leave it until the end of the week and the hole is at 500m?
Anyway, there was a good article in nature about PCD creation, how they tend to be heavy on gold or copper but never both as the creation method s for gold and copper are at different ends of the spectrum, i.e lower pressure v higher - lower temp v higher. Obviously near the middle you can get both.
It looks like the top section of the core is heavy in magnetite and quartz but lighter in chalco imo. But we know there is multiple creation waves here, hence the multiple stockwork.
So we have a quartz zone sat on top of the heavy chalco zone, with alteration in abundence, the quartz zone is likely imo to be lower copper but higher gold?
Maybe they release the the to emphasise the high gold content, then the next rns will be copper focused?
