With the core in the pictures, a lot has happened to that rock, there is definite veining to be seen. In the core cutting pic there is a bit sticking up that looks very much like sulphides. (I am restricted to my phone so can't post pictures). That white rock has been smashed by fluids to get like that, unless it is a primary limestone which i doubt. The stuff beneath that looks black in patches, especially on the fractured bits. As I said looks very much like chalcocite to me that is a secondary copper mineral formed by oxidising fluids. The driest core looks to be around 273m and that's the best image unfortunately. Considering where we are and what we are following up in C3 I see no reason to doubt good numbers here. All IMO. DYOR.
