A.I.S. Resources Limited announced that drilling commenced at the Guayatayoc Mina cateo in Northern Argentina on January 20, 2019. The target depth is 400 metres. 143 metres has been drilled so far. Brine sampling using a handheld resistivity meter has provided the following encouraging results: Resistivity 182 ms (micro siemens) (three times the salt concentration of sea water which is 54 ms). Specific Gravity is 1.12 (fresh water is 1.0) (lithium brines are usually 1.2-1.25). Ph is 7.12 (slightly alkaline which is possibly due to the presence of bi-carbonates that combine with Li, Ca, Mg, and other elements). Brine samples from the packer test at 102 metres depth will be sent to the laboratory this week for detailed analysis. The next packer test for brines will be at 250 metres. The drill core is composed of black and green clays down to 102 metres.
