Lake Resources is the company using Lilac's ion exchange lithium brine extraction technology.  Apparently they have several claims in Northern Argentina.  The Kachi project is still early in development and not near as far along as is Cauchari-Olaroz for LAC, also in Northern Argentia.

Well, it is, after all, still a lithium brine extraction technique so maybe or maybe not would it be a possible solution for LAC's Thacker Pass situation... after all, Thacker Pass is a lithium clay situation.
