what about tomorrow, page-30

re: the lineaments of croupier Vasco,
at this depth they want copper sulphides-chalco and bornite. Cuprite is an oxide and chalcocite,whilst technically a sulphide ,is more of a transitional ore which is only found in traditionally narrow bands.
Both the sulphides stand out visually and any half decent geo can give a broad grade range based on my personal experience-chalco looks like fools gold whereas bornite is 'peacock ore'.
In other words, the diamond core at this depth should give you a very good visual indicator for copper.
Looking at what has been posted by this company 12 months ago-it looks very suspiciously similar.
It is off my watch list for the time being.
Cheers,TAS
