A.I.S. Resources Limited announced that brine sampling commenced at the Guayatayoc Mina in Northern Argentina on January 29, 2019 at 295 metres depth. The target depth is 400 metres. Brine sampling using a handheld resistivity meter has provided the following encouraging results and confirms the previous results at 200m: Resistivity 188.5 ms (micro siemens) (three times the salt concentration of sea water which is 54 ms); Specific Gravity is 1.15 (fresh water is 1.0) (lithium brines are usually 1.2-1.25); Ph is 6.85 (slightly acid which is possibly due to the presence of chlorides that combine with Li, Ca, Mg, and other elements). Brine samples will be sent to SGS in Buenos Aires for testing and to Geoanalytics in Tucson to measure porosity and brine release characteristics. SGS will take about 10-14 days to process the samples after they receive them. The next packer test for brines will be at 325 metres where the maximum resistivity contrast occurred.
