West Australian gold exploration and development company Rox Resources Limited (“Rox” or “the Company”) (ASX: RXL), in conjunction with its joint venture partner Venus Metals Corporation (ASX: VMC), is pleased to report further significant assay results from the ongoing resource development program at the 3.2Moz Youanmi Gold Project (OYG JV), located near Mt Magnet in WA.
- Further assays received from Youanmi resource development drilling at Link. Results include:
- RXDD090: 5.86m @ 2.87g/t Au from 393.83m, incl: 2.87m @ 4.80g/t Au from 394.70m, and: 5.12m @ 4.46g/t Au from 479.33m, incl: 2.72m @ 6.81g/t Au from 480.12m
- RXDD094: 1.12m @ 13.07g/t Au from 434.88m
- RXDD090: 5.86m @ 2.87g/t Au from 393.83m, incl: 2.87m @ 4.80g/t Au from 394.70m, and: 5.12m @ 4.46g/t Au from 479.33m, incl: 2.72m @ 6.81g/t Au from 480.12m
- Drilling at Link has been targeting an upgrade in Resource category over a 460m strike length between 230m and 475m below surface. The consistency of the high-grade results received to date bodes well for future Resource updates as well as for potential depth extensions.
- Further drilling results received from near-mine exploration at Midway, including:
- RXDD073: 0.54m @ 16.17g/t Au from 290.65m
- RXDD074: 7.00m @ 5.95g/t Au from 87.00m
- RXDD085: 1.37m @ 21.89g/t Au from 354.69m
- RXRC462: 2.00m @ 7.93g/t Au from 142.00m
- Drilling completed at Midway has returned several high- grade results which continue to define the developing high-grade lode structure.
- Initial RC drilling to test potential supergene mineralisation and up-dip extensions at the Paddy’s Lode discovery has returned the following assays:
- RXRC481: 16.00m @ 1.38g/t Au from 56.00m
- RXRC483: 4.00m @ 5.33g/t from 202m
- Targeted geophysical survey (IP) has commenced at the Youanmi South area and Midway to identify potential high grade, dilatational zones along the mineralised structural corridor to be targeted in the next phase of drilling.
The assays are from a recently completed 28,507m (increased from 23,000m) resource development and near- mine exploration drilling program. Resource development drilling, which was focused on the high-priority Link and Kathleen areas of the project, was designed to convert Inferred Resources to the higher confidence Indicated Resource classification.
Drilling at Link was designed to target an upgrade of the Inferred Resource over a strike length of 460m and between 230m and 475m below surface. Assays received to date at Link have provided confidence in the geological interpretation and bode well for improving resource confidence as part of future resource updates, while also highlighting the down-dip potential of the ore zone.
Near-mine exploration drilling was focused on further evaluating the Midway exploration target identified in 2021, as well as the more recent Paddy’s Lode discovery in the Youanmi South Project area identified in early 2023.
Both prospects continue to demonstrate significant upside potential for the Youanmi Gold Project which will be an important focus for ongoing exploration. A geophysical survey has commenced recently to help further define the high-grade dilatational zones for the next phase of drill targeting.
Managing Director Comments
Rox Resources’ Managing Director, Mr Robert Ryan, said the latest drilling results continued to improve confidence in the Resource at Link while also reinforcing the exciting upside potential at both Midway and Paddy’s Lode.
“The latest two holes from Link continue to confirm the current geological interpretations and will improve the confidence in the Inferred Mineral Resources. Assays are outstanding for the four remaining diamond holes, which we expect will further increase confidence in the Resource and set the foundation for the Mineral Resource update targeted for later this year.
“Results from the near-mine discovery at Midway also continue to impress with high-grade results returned at excellent underground mining widths. The high-grade zone at Midway has been intersected over a 150m strike and 200m vertical extent and is still open along strike and down plunge.
“Meanwhile RC drilling at Paddy’s Lode targeting the potential for shallow high-grade material up-dip of the discovery holes has returned a broad zone of lower grade mineralisation close to the east-west offsetting fault.
“Our interpretation is that high-grade mineralisation appears to be constrained within 80m to 100m of the E-W fault, but remains open down-plunge. Similar to the Youanmi Main Lode and Link, further dilatations of the mineralised structure will yield further high-grade exploration targets and the geophysical survey currently underway will provide valuable information to target these high-grade zones both to the north, and stepping along strike to the south.
“We are still a long way from unravelling the potential of this emerging Paddy’s Lode area and we remain confident in the potential of this area to host a significant zone of high-grade mineralisation. With the help of the current geophysical survey, we look forward to getting rigs back on the ground for the next phase of exploration.”

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.

Galan Lithium
Overview
Argentina is no stranger to lithium mining. The South American nation is one of three encompassed in the prolific Lithium Triangle, a region that holds more than half of the world’s lithium deposits. Argentina ranks third in the world in terms of lithium reserves at 2.7 million metric tons (MT), concentrating lithium operations in the provinces of Jujuy, Salta and Catamarca.
Amidst electrification and decarbonization, analysts have forecasted a global supply deficit of 89,000 tons of lithium carbonate equivalent (LCE) in 2023 and the Argentinian government aims to double down on lithium to meet the increasing demand. Argentina has committed to $7 billion worth of investment for lithium production with strong growth projected for exports at $1.1 billion in 2023.
Galan Lithium (ASX:GLN,FSX:9CH) is an Australia-based international mining development company focused on its high-quality lithium brine projects in Argentina – Hombre Muerto West and Candelas. The company also holds a highly prospective lithium project in Australia – Greenbushes South.
The company’s flagship Hombre Muerto West (HMW) project hosts some of Argentina’s highest grade and lowest impurity levels with an inventory of 8.6 million tons (Mt) contained LCE @ 859 mg/L lithium, with 4.7 Mt contained LCE @ 866 mg/L Li in the measured category. The 100-percent-owned property also leverages close proximity to Livent Corporation’s El Fenix operation and Allkem’s Sal de Vida projects.
Galan has signed a commercial agreement with the Catamarca Government supporting the grant of permits to enable the commercialisation of lithium chloride concentrate from HMW to be sold locally or exported internationally.
Catamarca Governor Raúl Jalil and Galan Lithium Managing Director Juan Pablo Vargas de la Vega in Catamarca.
Galan’s secondary Candelas project comprises a sizable valley-filled channel with a potential indicated presence of substantially high-volume brine characteristics. The project’s maiden resource estimates stand upwards of 685 kilotons (kt) LCE, based on surveying from October 2019, and demonstrate exceptional discovery opportunities across this underexplored asset. Candelas has been rolled into Phase 4 of Galan’s targeted expansion plans, towards 60 ktpa LCE production by 2030.
Galan’s 100-percent-owned Greenbushes South Project is located in Western Australia and boasts advantageous positioning 3 kilometers south of the prolific Greenbushes lithium mine owned by Talison, Tianqi, IGO and Albermarle. Drilling of the first target was completed in July 2023. Galan is currently developing land access agreements for future drilling campaigns at Greenbushes South. An exploration license has been granted to the company for an additional key tenement, E70/4629 targeting lithium-bearing pegmatites for five years to February 2029. The tenement is approximately 260 kilometres south of Perth, the capital of Western Australia, and less than 30 kilometres south of the Greenbushes pegmatite at the Greenbushes Mine.
In 2023, Galan entered into an exclusive binding agreement with Redstone Resources to acquire 100 percent of the Camaro-Taiga-Hellcat property blocks from Infinity Stone Ventures (CSE:GEMS,GEMSF,FSE:B2I). The assets are located in the world-class James Bay Lithium Province in Quebec, collectively covering 5,187 hectares. The joint venture also includes an option to acquire 100 percent of the PAK East and PAK Southeast Lithium Project, spanning 1,415 hectares in Ontario’s Electric Avenue near Frontier Lithium’s PAK Lithium Project.

Key Projects
Hombre Muerto West Project
The 100-percent-owned Hombre Muerto West project is a large land property that sits on the west coast of the Hombre Muerto salar in Argentina, the second-best salar in the world for the production of lithium from brines. The property also leverages strategic positioning adjacent to notable competitors like Livent to the east.
Galan has increased HMW’s mineral resource to 8.6 Mt contained LCE @ 859 mg/L lithium (previously 7.3 Mt LCE @852 mg/L lithium), one of the highest grade resource estimates declared in Argentina. HMW’s measured resource is now at 4.7 Mt contained LCE @ 866mg/L lithium. Inclusion of the Catalina tenure adds ~1.3 Mt LCE to the HMW resource.
The pilot plant at HMW has validated the production of lithium chlorine concentrate, adding reagents to eliminate impurities, and generating a concentrate at 6 percent lithium. The plant comprises pre-concentration ponds, a lime plant, a filter press and concentration ponds.
Pilot Plant at HMW
Construction for Phase I has already commenced for 5.4 ktpa LCE production at HMW, and aims to deliver lithium chloride production in H1 2025. The fourth long-term pumping test (PBRS-03-23) results at HMW record an outstanding lithium mean grade of 981 mg/L - the highest reported grade from a production well in the Hombre Muerto Salar.
In April 2024, Galan announced 33 percent project completion with pond construction at 45 percent and project execution is advancing as planned.
A definitive feasibility study (DFS) for phase 2 shows a 20.85 ktpa LCE operation at HMW, targeting high-quality, 6 percent concentrated lithium chloride product (equivalent to 12.9 percent lithium oxide or 31.9 percent LCE) in 2026. The DFS also indicated phase 2 will deliver a post-tax NPV (8 percent) of US$2 billion, IRR of 43 percent and free cash flow of US$236 million per year. Phase 2 provides an exceptional foundation for significant economic upside in phases 3 and 4, targeting 60 ktpa LCE production by 2030.
The company has signed a binding term sheet with a wholly owned subsidiary of Glencore for offtake of up to 100 percent of its premium lithium chloride concentrate from HMW, and the offer to provide or facilitate a secured financing prepayment facility for US$70 to US$100 million, subject to conditions precedent being met.
Galan is targeting first-phase HMW lithium concentrate production in H1 2025
Galan now has 100 percent full ownership of the Catalina tenement that borders the Catamarca and Salta Provinces in Argentina. The newly secured Catalina tenure has a strong potential to significantly add to the existing HMW resource. The tenure also covers the Catalina, Rana de Sal II, Rana de Sal III, Pucara del Salar, Deseo I and Deceo II tenements.
Greenbushes South Lithium Project
The 100-percent-owned Greenbushes South lithium project is located near Perth, Western Australia, and is three kilometers south of the world-class Greenbushes lithium mine, managed by Talison Lithium. The Greenbushes South tenements can be found along the Donnybrook-Bridgetown Shear Zone geologic structure, which hosts the lithium-bearing pegmatites at the Greenbushes Lithium Mine.
Greenbushes South covers nearly 315 square kilometers, and hosts elevated pathfinder elements with well-defined anomalies adjacent to the property.
