The results outline a path to low-cost lithium extraction at Agua Fria with no expensive reagents or roasting required.
Mineralogy suggests there is potential to significantly beneficiate the mineralisation at Agua Fria and testing shows that most lithium was liberated rapidly at ambient temperature.
Adrian Griffin, managing director, commented: “These results are a great start to our metallurgical evaluation program and clearly show the potential to produce a valuable concentrate from the host volcanogenic sediments.
“The acid solubility of the lithium is of greater importance.
“The ability to leach the lithium in very short periods of time, at ambient temperature, and without the requirement of pre-treatment may have profound effects on the economics of Agua Fria, the next major lithium clay deposit.”
The Agua Fria prospect is focused on volcanogenic sediments which host widespread lithium mineralisation.
The sediments occur within the same geological sequence as Bacanora Minerals’ (CVE:BCN) La Ventana deposit which is currently being evaluated for production.
La Ventana is the largest documented lithium clay deposit and Agua Fria has a similar footprint.
Early indications are very promising with significant drill intervals having average values exceeding 1000 ppm lithium.
During early April, a 3,000 metre drilling program commenced at the Agua Fria prospect within the Electra Project.
The drilling program is being undertaken by local drilling contractors utilising a track mounted reverse circulation drill rig that provides good mobility.
The planned duration of the drilling campaign is 44 days.
