Ann: High grade Niobium results from Equador - Brazil, page-1026

Excavator marks !!! Hey that is the very key for me. In fact almost as good as a good drill intercept.

i.e. The local 'miners' found an outcrop of ore worth mining and took the best part away in a truck. Its pretty clear that pegmatite will have other rich spots, and even other pegmatites stacked below. I reckon the certainty level would be 60% to 80% of finding more with geophys overfly and close spaced drilling.

But then, everywhere they look they find these artisanal mines. So now what are the chances.
And rock chip grades are so high as to be nuts - to get a relative sample they would need to gather over a distance, crush and divide. That's time consuming and IMO better to go straight for RC drilling.

IMO SUM is absolutely crazy value - dont talk about WA1, it will be pedestrian by comparison.

DYOR.
