I think KLA are finding the "bonanza" grades @ 300-400 metres and the deeper they go the better it gets
If you look at what SIR did a few years ago - they found a motherload in the Fraser Range (Bollinger and Nova) and the SP rocketed from 5c to $5 in a matter of months.
Can this happen again?
Absolutely.
Just have to find a motherload.
