Some of the new extraction technologies claim to be able to be able to profitably extract lithium from brines with as little as 20 ppm lithium (see for example Pure Energy’s (TSXV:PE) 43-101 from last year). So I guess if this is true anything above 20 ppm would be a winner – but I remain somewhat skeptical.
$NWGC I agree RB! Theres gold AND lithium in our Rock Creek Claim! Definitely undervalued and I wonder if we do in fact here of the Nevada location....get ready for a very fast and aggressive rebound this week.
