MGX MINERALS COMPLETES TRENCHING AT SALINITAS LITHIUM PROJECT, SALTA PROVINCE, ARGENTINA; DRILLS TARGETS IDENTIFIED

MGX Minerals Inc.'s joint venture partner A.I.S. Resources Ltd. has received the final TEM (transient electromagnetics) geophysics report from Quantec. The report includes a detailed analysis and interpretation of the TEM profiles. Two major aquifer structures based on low resistivity have been identified.

A.I.S. exploration director and chief executive officer Phil Thomas undertook a 20-trench sampling program using a 321C Caterpillar excavator to trench down to five metres at each point selected at the Salinitas JV project in the Salinas Grandes salar, Salta province, Argentina. The objective was to identify the types of sediments with a specific resistivity close to the surface and identify the porosity of this unit, that is, stratigraphic units of green-grey clays, sand, black volcanic sands or brown clays. The black sands have a porosity of 22 to 32 per cent plus/minus 3 per cent.

Preparations have commenced to start a drilling program in the next two weeks subject to drill rig availability. Some drill pad preparation and roads have been upgraded and drill rig fluid pits have been dug at trench site 12 and 18 in preparation for drill hole 1, and if successful, drill hole 2.

About the Salinitas lithium brine project

The Salinitas tenements are located in the lithium triangle at the Salar de Salinas Grandes, in the province of Salta. The 4,308-hectare contiguous land package resides in the Puna region of northwest Argentina near the border of Chile, an area renowned for its lithium- and potassium-rich brine resources. MGX has partnered with A.I.S. on the project and MGX is currently earning an undivided 80-per-cent interest by incurring total exploration expenditures of at least $1.2-million (U.S.) by May 31, 2020, and by making payments totalling $3.2-million (U.S.) which are primarily due at that time.

Rapid lithium brine extraction technology

MGX has developed a rapid lithium extraction technology eliminating or greatly reducing the physical footprint and investment in large, multiphase, lake-sized, lined evaporation ponds, as well as enhancing the quality of extraction and recovery across a complex range of brines as compared with traditional solar evaporation. This technology is applicable to petrolithium (oil and gas waste water), natural brine, and other brine sources such as lithium-rich mine and industrial plant waste water. The technology was recently chosen as winner of the Base and Specialty Metals Industry Leadership Award at the 2018 S&P Global Platts Global Metals Awards, held in London in May (see press release dated May 18, 2018).
