Yeah hagetaka I think they are all knocking themselves over to secure supply from current Miners / producers at the moment because they need it now.
Largo is going bigger again as evidenced in the linked article, and plowing ahead buying back debt and posting record profits.

Hopefully once that is all tied up there will be some foresight and the next move will be getting potential new Vanadium miners / producers to secure future supply ??
Current miners can only supply so much and the projected increases in demand accompanied by shortfalls in supply can't be met solely by them one would imagine ?
