RE:POSCO Partnership
Very briefly, the way I see it, is that the POSCO partnership is very good for LAC. The decline in the SP has more to do with the fact that LAC has not been much, if at all, in the news since then (sometimes feels like a secret company, but for some, it's just management not wanting to push th stock more than necessary) The recent news of the pilot plant shipping to Argentina has boosted interest in the stock. For more on why the the stock has not performed as good as expected this year, you could take a look at some of the posts here. For a detailed overview of the company's prospects, take a look at this article : https://www.discoveryinvesting.com/blog/2014/9/12/as-lithium-nears-an-inflection-point-lithium-americas-poised-to-capitalize-on-the-growth
