Galan Lithium Limited (ASX:GLN) (Galan or the Company) is pleased to provide a further update on the progress of construction activities at its 100% owned Hombre Muerto West (HMW) Phase 1 lithium brine project, with lithium chloride production expected in H1 2025. Galan continues its steady progress in advancing its low cost, high grade HMW project to production in a timely manner.
- Pond 1 earthworks and liner installation (2.4kms in length) now completed;
- Filling of the remainder of pond 1 is currently underway; evaporation process commenced, being the first major step of Galan’s long-term production schedule
- Pond 2 earthworks construction progressing well (65% completed), liner installation to commence next week
- 9 production wells constructed offering operational flexibility; Phase 1 production only requires 6 wells
- HMW Project is a tier one project that will produce a premium high grade lithium chloride (LiCl) concentrate of 6% Li, comparable to 13% Li2O or 32% Lithium Carbonate Equivalent (LCE) in H1 2025
- Low all-in sustaining costs; HMW is in the 1st quartile of lithium industry’s cost curve with an initial reserve estimate of 40 years
- Operating cost of $US3,510/t LCE equates to a low Li2O equivalent operating cost of SC6 $US310/t-$US350/t; equates to solid production margins at current spot prices
- Glencore due diligence continues
As previously announced, the HMW project was separated into four production phases. The initial Phase 1 Definitive Feasibility Study (DFS) focused on the production of 5.4ktpa LCE of a lithium chloride concentrate by H1 2025, as governed by the approved production permits. The Phase 2 DFS targets 21ktpa LCE of a lithium chloride concentrate in 2026, followed by Phase 3 production of 40ktpa LCE by 2028 and finally a Phase 4 production target of 60ktpa LCE by 2030. Phase 4 will include lithium brine sourced from both HMW and Galan’s other 100% owned project in Argentina, Candelas. The very positive Phase 2 DFS results were announced on 3 October 2023 (https://wcsecure.weblink.com.au/pdf/GLN/02720109.pdf).
Galan’s Managing Director, Juan Pablo (JP) Vargas de la Vega, commented:
“The completion of earthworks and the installation of liners for Pond 1 represents a significant milestone for the HMW Phase 1 construction team. Evaporation has now commenced which is the first step of the Company’s long-term production schedule for its low-cost, low-risk lithium chloride development strategy, as Galan looks to become the next lithium producer in Argentina in H1 2025.”
Construction progress at HMW (February 2024)
The brine well field is located in the same area as the HMW ponds system. The well field for Phases 1 and 2 are exclusively located in the Rana de Sal, Del Condor, Deceo III, Pata Pila, Casa del Inca III & IV, and Santa Barbara XXIV mining tenements. The HMW Project also has several tenements (including Catalina) with potential to further increase the quantity and quality of the brine resources, which may result in additional production.

New Drilling and Exploration Programs Launched for Critical Minerals and Gold Targets in World-Class Australian Mineral Provinces
- A series of new drilling and exploration programs have been launched, testing Critical Minerals and gold targets across three key project areas. These projects all lie along strike from major deposits in world-class mineral provinces in Western Australia and the Northern Territory (see locations, Figure 1).
- The exploration programs at these highly prospective projects, acquired through the purchase of an 80% interest in Payne Gully Gold Pty Ltd1, include:
- Initial drilling of un-tested key copper-gold target corridor at the Warrego East Copper-Gold Project within the Tennant Creek Mineral Field (TCMF) in the NT (see Figure 1), which has historically produced 25Mt @ 6.9 g/t Au and 2.8% Cu2. The granted Warrego East EL32725 lies directly east of Warrego, the largest historical mine at Tennant Creek, which produced 6.75Mt @ 1.9% Cu, 6.6 g/t Au2, and covers a fault corridor interpreted from detailed magnetics and the Company’s gravity survey that connects Warrego with the Gecko and Orlando copper-gold deposits (past production and resources 11Mt @ 2.3% Cu, 1.8 g/t Au2,3 – see Figure 2). A Mine Management Plan (MMP) has been submitted to the NT Government for approval for an extensive aircore drilling program and follow-up RC/diamond drilling across ironstone hosted copper-gold targets which have not been previously tested. The Company also has four EL applications in the TCMF, all of which sit on key mineralised corridors (see Figures 2 & 3).
- Initial drilling of lithium-pegmatite targets on the Warrambie Critical Minerals (Li, Ni-Cu-Co) Project in WA’s northwest Pilbara (see Figure 1). Warrambie is located just 10km east of the major Andover lithium discovery which has produced drilling intersections of up to 209m @ 1.42% Li2O4. Targets have been defined by detailed gravity and reprocessed magnetics imagery5 which are analogous to the Andover geophysical signature but have not previously been tested due to the presence of shallow soil cover. A Program of Work (PoW) has been submitted to the WA Department of Energy, Mines, Industry Regulation and Safety (DEMIRS) for approval to drill a series of aircore drilling traverses and follow-up with RC or diamond drilling across identified lithium pegmatite targets (see Figures 4 & 5). This program is expected to commence during H2 2024.
- An aeromagnetic (fixed wing) survey is underway across the granted gold tenements located along strike to the northeast of the 5Moz Big Bell gold deposit in WA’s Murchison Gold Province. (see Figures 1 & 6). The tenements cover a 50km strike length of the regional scale Chunderloo Shear Zone and regional magnetics show potential for greenstone and potentially gold-mineralised splay structures which have not been tested in areas of cover1. The detailed aeromagnetics will define these targets prior to planned aircore drilling to test bedrock targets.
Metals Australia CEO Paul Ferguson commented:
“These new exploration programs are important steps in advancing our extensive and highly prospective Critical Minerals and gold projects in WA and the NT, which are all located along strike from major deposits in world-class mineralised terranes.
High-quality drilling targets have been identified by our geological team at the Tennant Creek project, east of the high-grade Warrego copper-gold mine, and at our Warrambie project in the northwest Pilbara, which is only 10km east of the major Andover lithium discovery. We have also commenced a detailed aeromagnetic survey across a large project area located directly along strike from the 5-million-ounce Big Bell mine in WA’s Murchison district.
With exploration programs across five key projects in Australia and Canada, the second half of 2024 will be an extremely exciting period for the Company as we look to unlock the value of our portfolio.”
The target areas being tested are all located along strike from major mineral deposits (see Figure 1, below).

Warrego East Copper-Gold Targets, Tennant Creek, NT
The Company’s Tennant Creek Project includes granted EL32725 at Warrego East and four EL applications, EL32397, EL32837, EL32410 and the more recent EL33853, located in the Tennant Creek Mineral Field (TCMF) (see Figure 2 below).
The TCMF has produced 25Mt @ 6.9 g/t gold (Au) & 2.8% copper (Cu) historically2, the equivalent of more than 8.5Moz or $20 billion worth of gold at current prices, with all production coming from deposits in outcropping areas.

PFS Plant Location Study Results in Decision to Locate Carbonation Plant in Mining Centre of Copiapó
Highlights:
- A plant location study was completed by Worley, which evaluated the optimal plant location configuration for the Laguna Verde project, based on a capacity of 20,000 tonnes per annum of battery grade lithium carbonate equivalent (LCE)
- This provided a trade-off analysis between locating the entire plant at Laguna Verde versus splitting plant facilities between Laguna Verde and the nearby mining centre of Copiapó
- The option of locating the DLE plant and eluate concentration stages at the Laguna Verde site, and the carbonation plant at Copiapó is highly favourable, resulting in the decision to proceed with this option
- A concentrated eluate with 6% lithium, the maximum concentration before lithium salts begin to precipitate, will be transported to Copiapó for impurity removal and carbonation stages
- This configuration results in a minor increase in volumes transported while taking advantage of Copiapó's well-developed infrastructure and better access to a skilled workforce
- According to the Lanshen plant design, approximately 70% of the operational workforce will be employed at the carbonation plant, locating it in Copiapó provides major advantages in hiring a local work force including diversity outcomes such as greater female participation, while contributing to the local economy
- The footprint at the project site, which is at 4300m above sea level, will be greatly reduced, from power supply, storage, camp and plant facilities, construction phase impacts, and environmental impacts
- The carbonation plant in Copiapó would eventually be expanded to also treat concentrated eluate from the Viento Andino project
- The PFS, now due for completion before the end of Q4 this year, will include updated capex and opex estimates and will further determine the optimal production development strategy
Steve Kesler, Executive Chairman and Interim Chief Executive Officer, CleanTech Lithium PLC, said:
"We undertook a plant location study as part of our ongoing PFS for the Laguna Verde project resulting in the decision to locate the DLE and eluate concentration stages at the project site, and the carbonation plant in Copiapó. This will have various benefits such as reducing the footprint and impacts at Laguna Verde, and taking advantage of existing infrastructure, power supply and skilled workforce in Copiapó. The plant at Copiapó can then be expanded to treat material from our Viento Andino project and potentially others. The decision on plant configuration will feed directly into the wider PFS which is due to be completed later this year."
Further Information
The Company engaged Worley, utilising its local Santiago based office, to undertake the PFS for the Laguna Verde project, and selected Lanshen as designer and supplier of the entire DLE processing plant. Worley recently performed various trade-off or options studies to consider the most favourable configuration of the project and a plant location option study which assessed three scenarios for location of the plant, of which two of the scenarios, labelled Scenario 1 and Scenario 3 in the report, provided the relevant trade-off comparison:
- Scenario 1: Locating the entire plant based at the Laguna Verde project site
- Scenario 3: Locating DLE and eluate concentration stages at the project site, and the impurity removal and carbonation (downstream plant) at Copiapó
Laguna Verde is connected to Copiapó via a 270km paved international highway, as shown in Figure 1. Copiapó is a major regional mining centre in Chile with a population of 175,000, having well established infrastructure, a skilled workforce, and existing supply hubs for reagents and other materials. While basing the entire plant at the project site is feasible and most lithium projects in the lithium triangle are proceeding on such a basis, the good transport link and relative proximity to Copiapó made a trade-off study valuable.
Figure 1: Regional Map
An analysis of the difference in transport volumes was undertaken showing a minimal overall difference between the two scenarios. For Scenario 3 where impurity removal and carbonation stages are in Copiapó, there will be no transport of reagents or bulk chemicals to Laguna Verde which has a positive environmental and community impact.
A qualitative assessment was then undertaken by the Company across the range of metrics as shown in Figure 2. There are only two metrics in which Scenario 1 where the entire plant is located at site has a significantly positive comparison. The first one is storage during the construction phase, in that it will require a single storage facility rather than storage at both locations for tools, materials and spare parts. The second is disposal of solids, which is largely Sodium Chloride (NaCl or table salt) that is dissolved in the eluate and removed in the impurity removal stage before carbonation. In Scenario 1, these would be re-dissolved in the spent brine and re-injected. In Scenario 3, the report assumed NaCl would need to be disposed in Copiapó at a cost. However there should be a ready market for NaCl and further evaluation of this is required.
Figure 2: Qualitative Comparison- All on site (1) and split plants (3)
Across a range of other metrics the Scenario 3 of locating the downstream plant at Copiapó has major advantages. According to Lanshen, approximately 70% of the operational labour force will work at the downstream plant, which provides a far superior option for skilled workforce based in Copiapó. The footprint at the project site will be greatly reduced, from power supply, storage, camp and plant facilities, construction phase impacts, and environmental impacts. The Board has accepted the study and the decision to split the plant facilities between the project site and Copiapó will be the basis for the PFS.
