Promising signs for Galan at Candelas
Field measurements released by Galan Lithium Ltd (ASX:GLN) indicate that the upper levels of a brine bearing aquifer have been encountered in the fifth drillhole (C-05-19) at the Candelas Lithium Brine Project on the Hombre Muerto salar in Argentina.
Galan is exploring for lithium brines in highly prospective territory of South America, an area known as the Lithium Triangle.
Hombre Muerto is proven to host the highest grade and lowest impurity levels within Argentina and is home to Livent Corporation’s El Fenix operation and Galaxy Resources and POSCO’s Sal de Vida projects.
The fifth drillhole is approximately 2.4 kilometres south-west of the maiden drillhole which returned excellent metrics of 192 metres at 802 mg/l lithium.
Further, it is only 1.8 kilometres west of the third drillhole (C-03-19) which featured 143 metres at 784 mg/l lithium with low impurities.
Positive implications for broader Candelas project
Importantly, the geological sequence largely replicates that observed in the other drillholes.
The hole encountered a sequence of sands and clays hosting salty waters which then turned to brines hosted within a permeable breccia-conglomerate.
Conductivity measurements from brine samples taken from packer testing an interval from 280 metres to 320 metres exceeded the 200 millisiemens/cm limits of the field recording instrument whilst high specific gravity was recorded at 1.195 grams per cubic centimetre.
Highlighting the significance of these results in terms of the broader project, Galan’s managing director, Juan Pablo Vargas de la Vega said, “The discovery of further brines confirms that there is consistent brine coverage over a large area in this northern part of the Candelas channel.
“The result reinforces our view that the project has the potential to host a significant lithium resource on one of the world’s premium salars at Hombre Muerto.
“We look forward to finalising the hole and confirming that grades and impurity levels are consistent with those already observed in this area”.
Drilling is currently at 330 metres, and the fact that it is still in brine is encouraging in terms of ongoing exploration updates.
Consequently, there could be a run of newsflow similar to that which prompted a three-fold increase in the company’s share price between December 2018 and March.
Once complete, downhole geophysical logging will be conducted, and further packer tests performed to collect samples for analyses.
