Below is a link to another article and a video about the situation at Cauchari-Olaroz.  Again, keep in mind the bias of the reporting source when reading and viewing, but it doesn't appear to be favorable in the least to Minera Exar and, thus to the Ganfeng-LAC Joint Venture in Argentina.  Translation required for those who do not speak Spanish.
