@Tcb007 - They come on like bees around the honey pot - I cannot understand them myself. I characterise them as 'sad sacks'

And I strongly agree with you, we are here on HC to discuss our stocks including their strong points - (my aim is always to help others to understand so they can make a more informed assessment - I long ago realised that some of my gains come from the general appreciation in the value of the tickers I hold, but some comes from other peoples losses, and I would always hope that spreading what little knowledge I have would minimize that)

So anyway here is some info on the minerals tantalite, the source of tantalum, and columbite, the source of niobium. From Wikipedia

The mineral in Sandro's vid. as posted by @THE Archetect could be Tantalite - the ore for Tantalum. Ta is even more valuable than Nb (with which it is often associated). If SUM has a deposit then we could say 'Move over WA1 we are on a bigger rocket ship'

Only the assays will tell us which it is - or some of both - but THANK-YOU SANDRO, we all love you for sharing your finds with us.
