Ann: High grade Niobium results from Equador - Brazil, page-226

TA and NB pretty hard to separate from columbite"? Not that easy to separate from phyroclor either! Considering columbite and phyroclor are both essentially crystals, and initial metallurgy from WA1 Luni deposit contains both I really do not see your point?

Or are you saying the columbite is too hard to separate from quartz/feldspar? But isn't that what a crusher circuit is for?

As for rock chip assays! Yes it's easy to be cynical but typically junior explorers use a low cost method to confirm mineralisation prior to drill planning. It's not unusual at all tbh

Pegmatite length is 1km with reports the pegmatite is stacked which usually indicates it's at depth. I would love to know actual depth but drilling the target is the best way to define an answer on that one.

Best of luck with WA1 mate! Bought early at 70c and made some good coin but no longer hold unfortunately
Hope Regal do not get too brutal on you guys but hey it's Regal being Regal huh.
