Hi Lenno yes I think most of the regular posters are aware that Kachi is a huge resource with lower grades than others in the area but I dont think that anyone has questioned about the lower grades being non commercial. The process produces lithium at a high purity which would seem to offset the fact that the brine in situ is at a lower concentration. The return to aquifer is a technical problem but again I havent heard anyone express a concern that it cant be done for heavens sake the evaporation ponds are lined so that the brine doesnt leach back into the aquifer.
