I was just about to post that link, Bob.  You beat me to it.  It is full of information about their efforts in South America and it really promotes their relationship with Ganfeng and their minimal processing in order to produce a commercially viable Lithium Chloride.  From that June 2021, Corporate Presentation is the following highlight regarding the advantage of producing Lithium Chloride:

"Fast Track to Production by producing high purity LiCl on site vs lithium carbonate ►Arena has developed a proprietary brine processing technology producing >30% LiCl directly from evaporation ponds ►LiCl can be sold and transported to chemical plants worldwide ►This approach reduces capital requirements, operational risk while producing a higher quality product."

The presentation spares nothing in promoting Eduardo Morales as its Executive Chairman.

Quote an interesting read overall.
