Yeah, I know it's crazy but look at the evidence. Don't take my word for it.
The Witwatersrand was multiple, extensive, but thin parallel reefs.
BBX's mineralisation is massive, disseminated, with localised variation in the grades within a broad, pervasive, intense hydrothermal alteration zones that persist in dolerite and porphyry country rock. Every single result spread out across 1km of strike at Tres Estados returned high grade numbers. As the thread title sates, 100% ore. No barren fresh rock encountered yet. I'm sure at some stage we'll manage to find some low or waste grades, so maybe 60 or 80% of the rock mass is mineralised, so maybe we've only got 1.2Boz in that sq. km. Who knows. Time will tell.
I suggest you spend some time studying the evidence. It could be time well spent.
