I don't understand a thing about geology (which might have to be a correspondence course for me soon).
I did see a report from Cannacord Genuity (perhaps a French investment outfit) regarding tin which showed the YTC grades to be not as high as the best but around the middle, whereas the quantity from memory was fairly high. I can no longer access the report and it was up on a listed tin miner's website which is how I read it, then it was taken down. As YTC has been acquiring other tin explorers nearby I think they will in time be able to make a case for some viable production.
This reply is inept, but is in place of any other responses to date.
