I'm not confident these pegs will have the scale/grade to make bank either, but the met work looks simple enough... Cheap gravity separation of columbite-tantalite from the pegs should produce a high-grade con without the need for float tanks of reagents. Question remains about the grade and scale of these 'stacked pegmatites' for bulk mining, because it will only make sense on the scale of bulk mining.
How about SUM actually do some costean samples across the pegmatites like geo's have done for ever in this style of deposit to give us an idea of the width and grade of the pegs? Too easy, yet nada...
