Some numbers for the interested, copper-rich minerals seen in mineralised core:
Native Copper (Cu): 100% Cu content Chalcocite (Cu2S): 79.8% Cu content Covellite (CuS): 66.4% Cu content Bornite (Cu5FeS4): 63.5% Cu content Chalcopyrite (CuFeS2): 34.8% Cu content
The deposit is known for its skarn mineralisation containing chalcocite and bornite through the marbles. The more Bornite, the more purple-blue is seen (the tarnished colour of bornite). The more chalcocite, the more dark grey to black colour is seen through the core. Decent intersections will be a range of blues and dark blues with black spotting, and less whitish-grey of marble (diluting the Cu grade).
It's unlikely that native copper will be intersected, but if it is get your party hats ready.
