High-Flow, High-Grade Long-Term Pumping Test Results Continue

Galan Lithium Limited (ASX:GLN)LN) (Galan or the Company) is pleased to provide an update on the well pumping test and exploration programs for its 100%-owned Hombre Muerto West Lithium Project (HMW Project), located on the Western Basin of the Hombre Muerto salar in Catamarca Province, Argentina. The pumping tests are an integral part of the current DFS for the HMW Project.

Highlights:

• Long term pumping test at Pata Pila (PPB-01-21) successfully completed; pumping rates between 17 and 20 L/s, with extracted Li grade between 821 and 927 mg/L.
• These strong outcomes support potential higher production capacity parameters for Definitive Feasibility Study (DFS) inputs.
• First pumping well at Rana de Sal (PBRS-01-21) under hydraulic testing; 72-hour constant rate test executed at steady 20 L/s and average Li grade over 945 mg/L.
• Pumping test program ongoing with 30-day pumping test at PBRS-01-21 to commence shortly, plus hydraulic testing of second Pata Pila well (PPB-02-22).
• Two (2) diamond drilling exploration wells at Rana de Sal returned thick sedimentary intersections with high Li grades (942 – 1,035 mg/L).
• Casa del Inca exploration drillhole completed at 155 metres with intervals of high porosity potential sediments underlying surface lava flows.

“These 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. These outcomes provide further validation of the world-class nature of the HMW Project and its planned development.”

Well pump testing program delivering excellent results

Pata Pila

The 30-day long term pumping test at the first Pata Pila well (PPB-01-21) was successfully completed at the end of July. The sustained pumping rates were solid, ranging between 17 and 20 L/s. More than 150 brine samples were collected during this testing phase, with laboratory analysis returning an average Li grade of 874 mg/L (from a range of 821 to 927 mg /L).

The hydraulic testing of the second pumping well at Pata Pila (PPB-02-22) is set to commence shortly. This well is located approximately 800m upgradient in the Pata Pila alluvial fan (see Figure 1).
