"Given how many companies have dropped Lilac...." this is the old high school argument she dropped him, no he dropped her. The company you speak of was working with Lilac and was working with Alex Grant, but now are not. Why? We don't know, if you know, please tell. Every lithium deposit has its own issues. You raised the issue of altitude, but then said you used altitude to convey remoteness. Hint if you think Kachi is remote say remote because we have had a poster complaining for years about altitude it's a well-worn non issue. Argentina on the brink of economic collapse is about as accurate as saying that the USA is on the brink of political collapse.
Good luck with your investments I think that it will be pretty hard to lose money in the lithium sector, but some will manage it.
