Let's not disregard the potential value of tantalum either.
Tantalum generally being a by product of Lithium mining.
It is not a very well known metal but is a strategic, rare metal with some importance.
It is used in electric conductors and almost every electronic device you use contains Tantalum. It also is a key metal in superalloys.
Presently about half the world's supply of Tantalum comes from Africa and as a result there is a fair amount of sovereign risk, however australia, with a focus on Lithium mine development is looking to take a much greater share with the obvious minimal sovereign risk.
As fantastic as it is, Lithium isn't the only value add at Trigg Hill.
Tantalum currently is about $130 a pound. Food for thought!
