Galan’s lithium brine pumping test results progress DFS at Hombre Muerto West

Galan Lithium says strong outcomes from pumping tests at the Hombre Muerto West Lithium Brine Project in Argentina support potential higher production capacity parameters for Definitive Feasibility Study (DFS) inputs.
The long-term pumping test at Pata Pila (PPB-01-21) showed pumping rates between 17 and 20 L/s, with extracted Li grade between 821 and 927 mg/L.
And a 72-hour constant rate test at Rana de Sal was executed at steady 20L/s and average Li grade over 945mg/L – and two diamond drilling exploration wells returned thick sedimentary intersections with high Li grades of 942 – 1,035mg/L.
Galan Lithium (ASX:GLN) exploration manager Alvaro Henriquez said the results are great news from both an underlying geological, and resource confidence, point of view.
“We have demonstrated a high production capacity with the completion of the first long-term pumping test at Pata Pila, as well as extending the reservoir quality throughout the main alluvial deposits on our tenements with the latest exploration well intercepts,” Henriquez said.
“These outcomes provide further validation of the world-class nature of the HMW Project and its planned development.”
The pumping test program is ongoing with a 30-day pumping test at PBRS-01-21 to commence shortly, plus hydraulic testing of a second Pata Pila well (PPB-02-22).
The pumping tests are expected to conclude in early October 2022, with all data obtained being analysed as part of the development of the Resource and Reserve model for the Project.
Exploration drilling is continuing at the HMW Project with the next drillhole (CI-01-22) located at Casa del Inca.
This drillhole is designed to validate the potential hydrogeological extension of the brine reservoir between the Pata Pila alluvial fan and salar margin below recent lava flows in Casa del Inca, as suggested by surface resistivity surveys.
Drilling at CI-01-22 shows a fractured basalt unit overlying unconsolidated sands and gravels. The drillhole was completed to a depth of 155m.
Following the finalization of CI-01-22, drilling will commence in del Condor, with the aim of improving certainty in the area connecting Rana de Sal and Pata Pila for the updated resource.
