Earlier this week the company confirmed that its fifth drill hole at the Candelas Lithium Brine Project on the Hombre Muerto salar in Argentina had returned 160 metres of lithium brine.
Initial field testing indicated a brine section with specific gravity up to 1.13 and conductivity of more than 200 mS/cm.
The hole, C-05-19, is about 2.5 kilometres south of maiden drill hole C-01-19 which provided strong results, including an intersection of 192 metres at 802 mg/I lithium with low impurities.
Following geophysical logging several packer tests were performed, and samples collected and sent for analyses.
In mid-May Galan received required permits for a stage II drilling program of six holes at Candelas.
These holes will focus on the northern section of the property with the aim of defining a maiden JORC resource during the September quarter 2019.
