Ann: Sandfire Resources Increase in Relevant Interest, page-67

A lot of professionals have been caught out here @sharman so it's not something about which you ought to be embarassed.
Rupice is unique. That is not hyperbole. I haven't done the research but nobody has come up with a comparable orebody that has standalone grades of Au, Ag & Zn and includes Pb, Cu & barite.
I'm not going to say there are repeats of Rupice nearby but management knows from old Yugoslav-era data that in the region there are other orebodies and in those days they weren't assaying for PMs.
Also, reading between the lines, some of the $25m just raised will be spent acquiring more land between Rupice and Veovaca, a distance of 15km I think. In Bosnia exploration permits cost USD500k per sqkm from memory.
So there's upside from exploration as well as from the market getting a better understanding of what is already "in the bag".
Apparently North American investors are still not fully appraised of ADT.
