Pursuit Minerals
Overview
Pursuit Minerals Ltd. (ASX:PUR) is a top-tier lithium exploration and development company. The company is focused on its flagship Rio Grande Sur lithium project in the Salta Province of Argentina. The project is strategically located in an area known as the Lithium Triangle which hosts 50 percent of the global lithium resources and 40 percent of the current global lithium production. Argentina is the world’s third largest producer of lithium, behind Australia and Chile.
The project spans an area of 9,260 hectares on the Rio Grande Salar and is adjacent to several operating lithium mines and development operations, including Acradium Lithium’s Fenix lithium mine and the Olaroz lithium mine. The Rio Grande Salar holds a historical Ni 43-101 resource declared by LSC Lithium, formerly listed on the TSX prior to being acquired by Plus Petrol of 2.1 million tons (Mt) of lithium carbonate equivalent (LCE) with an average grade of 370 milligrams per litre (mg/L). This resource was mostly obtained from shallow drilling to 100 metres.
Pursuit delivered a maiden JORC Inferred Mineral Resource Estimate (MRE) of 251.3 kt LCE at 351 mg/L at the Rio Grande Sur project. The inferred resource relies on recent geophysical surveys and historical drilling, encompassing only a small portion of the known mineralization. Notably, excluding the highly promising Mito tenement from the current MRE highlights the unexplored potential for further resource expansion.
Pursuit has commenced its Stage 1 maiden drill program focused on upgrading the inferred resource. The drilling is anticipated to reach depths of 500 to 600 metres below surface, significantly deeper than the existing defined JORC mineral resource depth. Other companies in the region have obtained impressive results and grades of 900 mg/Li+ at depths of 500 metres, some of the highest known grades in Argentina. Pursuit expects a material resource upgrade in the second half of 2024 which will build on the inferred maiden resource.

In addition to having an attractive lithium resource, Pursuit is focused on the production of lithium carbonate to meet the supply side response to growing lithium demand. Recently, the company announced the first phase of operations of its 250 tons per annum (tpa) pilot plant to produce lithium carbonate. The plant will generate both technical and battery grade lithium carbonate at a purity of 99.95 percent, employing a conventional evaporation process.
Pursuit has submitted advanced environmental permits for the construction of the 250 tpa evaporation ponds and Stage 2 drill program at the northern tenement of the Rio Grande Sur project.
The establishment of the ponds is expected to take place in the latter part of 2024, pending environmental approvals. The ponds and the plant are planned to be situated on the Sal Rio 02 tenement enabling the possibility of initiating the first production of lithium carbonate on-site in 2025.
Pursuit is targeting continuous production at Rio Grande Salar and expects the current setup to be scalable to produce 15,000 to 20,000tpa of technical and battery grade lithium carbonate.
250-ton lithium carbonate pilot plant
The company’s focus on Argentina has several advantages. The new government, led by its president Javier Milei has signaled a market-friendly and pro-business policy shift. This should be a positive development for lithium miners given that Argentina has one of the largest lithium reserves in the world. Argentina holds 21 percent of the world’s 105 million tons of lithium resources, second only to Bolivia, according to the United States Geological Survey’s Lithium Statistics and Information 2024 report.
Lithium is in great demand driven by the growth in electric vehicles (EVs). Bloomberg NEF estimates lithium demand to jump by 225 percent to 2.6 Mt of LCE by 2030, translating into a CAGR of 16 percent. In a net-zero scenario, Bloomberg pegs the demand at 3.6 Mt of LCE by 2030, a CAGR of 19 percent.
The company remains focused on project execution that will deliver long-term shareholder value, including the completion of stage 1 drilling, JORC resource upgrade, first production of lithium carbonate and increasing production capacity to 250 tpa, and receipt of environmental permits, all within the first half of 2024.
In addition, Pursuit has identified the following catalysts over the next 12 months:
- Q3/Q4 2024: start of evaporation pond construction at Rio Grande, off-take agreement, relocation of 250 tpa pilot plant to Rio Grande.
- Q4 2024/Q1 2025: Detailed mineral resource study for commercial scale lithium carbonate operation; stage 2 drilling and JORC resource upgrade; first production from 250 tpa plant could commence as early as Q4 of 2025.
Company Highlights
- Pursuit Minerals is an ASX-listed company focused on advancing a pre-production lithium brine operation in Argentina.
- The company’s flagship Rio Grande Sur project covers 9,233 hectares on the Rio Grande Salar, in the Salta Province of Argentina located in the Lithium Triangle. The region is home to 50 percent of global lithium resources and 40 percent of world production.
- The acreage owned by Pursuit is situated within an Ni 43-101 inferred resource of 2.1 million metric tons of lithium carbonate equivalent (LCE), with an average grade of 370 milligrams per litre (mg/L) extending to a depth of 100 metres.
- Pursuit delivered a maiden JORC Inferred Mineral Resource Estimate (MRE) of 251.3 kt LCE at 351 mg/L at the Rio Grande Sur Project. With its current Stage 1 drilling program currently underway, Pursuit is targeting a material resource upgrade in the second quarter of 2024, which will build on the recent inferred maiden resource.
- The company has commenced the first phase of operations to produce lithium carbonate at its recently commissioned pilot plant, which is expected to achieve an operational capacity of 250 tons per annum (tpa). This is a significant milestone in the journey to advance toward the first production at Rio Grande Sur.
- Despite temporary fluctuations in lithium carbonate prices, the market continues to demonstrate resilience, with long-term projections indicating a significant 225 percent surge to reach 2.6 million tons of LCE worldwide by 2030.
Key Project
Rio Grande Sur Lithium Project
The Rio Grande Sur is the company’s flagship lithium project. The project comprises five tenements that span 9,233 hectares and are located in Rio Grande Salar in Salta province, Argentina. The region has benefited from historical exploration that yielded an NI 43-101 resource of 2.19 Mt LCE @ 374 mg/L, at inferred category.
During Q4 2023, Pursuit announced a maiden JORC inferred mineral resource estimate of 251.3 kt LCE at 351 mg/L at the Rio Grande Sur project. Following this, Pursuit is currently undertaking a maiden drill program to upgrade the inferred resource. Stage 1 of the drill program will comprise four diamond drill holes on the southern tenements. The first two holes will be drilled at the Sal Rio II and Maria Magdelena tenements.
The drilling is anticipated to reach depths of 500 to 600 metres below surface, significantly deeper than the existing defined JORC mineral resource depth. The drilling commenced in Q1 2024, and Pursuit is targeting a material resource upgrade in the second quarter of 2024. Further drilling is expected following the completion of the Stage 1 program. The Stage 2 drilling program is anticipated to occur in the second half of 2024, after which Pursuit is targeting a feasibility study.

Where Does Tesla Get its Lithium? (Updated 2024)
In a mid-2023 Tesla earnings call, Musk seemed relieved to see prices for the battery metal had declined. “Lithium prices went absolutely insane there for a while,” he said. Lower battery prices will bring EVs closer to cost parity with internal combustion engines vehicles, leading to wider adoption and increased demand.
During the 2024 US presidential election, Musk threw his support behind Republican candidate and former president Donald Trump, who has been historically critical on electric vehicles and subsidies. Following Trump's election win on November 5, AP News reported that these stances could support Tesla as they would be more likely to harm smaller competitors who were less established than the EV giant. Tesla's share price shot upwards in response to the election outcome.
This spring, Musk invited Argentine President Javier Milei to the Tesla factory in Austin, Texas, where the two reportedly discussed the investment opportunities in Argentina's lithium sector. As a prominent member of the prolific Lithium Triangle, the South American nation is the fourth leading lithium producer by country.
Australia's hard-rock deposits and Chile's brines are also top sources for the world's lithium supply. But lithium refining is dominated by China, which accounted for 72 percent of global lithium processing capacity in 2022.
With the limelight on Musk and Tesla in 2024, investors should know where the electric car company sources its lithium.
Read on to learn more about where Tesla gets its lithium, how much lithium is in a Tesla battery and what the EV maker is doing to better secure its lithium supply chain.
In this article
Which lithium companies supply Tesla?
Tesla has deals with multiple lithium suppliers, some that are already producers and some that are juniors developing lithium projects.
At the end of 2021, Tesla inked a three-year lithium supply deal with top lithium producer Ganfeng Lithium (OTC Pink:GNENF,SZSE:002460), and the Chinese company began providing products to Tesla starting in 2022. Major miner Arcadium Lithium (NYSE:ALTM,ASX:LTM), which is set to be acquired by Rio Tinto (ASX:RIO,NYSE:RIO,LSE:RIO) also has supply contracts in place with the EV maker.
China’s Sichuan Yahua Industrial Group (SZSE:002497) agreed to supply battery-grade lithium hydroxide to Tesla through 2030. Under a new, separate agreement finalized in June 2024, Yahua is set to supply Tesla with an unspecified amount of lithium carbonate between 2025 and 2027, with the option to extend the contract by another year.
Tesla also holds deals with junior miners for production that is yet to come on stream. Liontown Resources (ASX:LTR,OTC Pink:LINRF) is set to supply Tesla with lithium spodumene concentrate from its AU$473 million Kathleen Valley project. The deal is for an initial five year period set to begin this year, and production began in July 2024.The company expects to reach nameplate capacity in calendar Q1 2025.
In January 2023, Tesla amended its agreement with Piedmont Lithium (ASX:PLL,NASDAQ:PLL), which now supplies the US automaker with spodumene concentrate from its North American Lithium operation, a joint venture with Sayona Mining (ASX:SYA,OTCQB:SYAXF). The deal is in place through the end of 2025.
Even though Tesla has secured lithium from all these companies, the EV supply chain is a bit more complex than just buying lithium directly from miners. Tesla also works with battery makers, such as Panasonic (OTC Pink:PCRFF,TSE:6752) and CATL (SZSE:300750), which themselves work with other chemical companies that secure their own lithium deals.
What are Tesla batteries made of?
Tesla vehicles use several different battery cathodes, including nickel-cobalt-aluminum (NCA) cathodes and lithium-iron-phosphate (LFP) cathodes.
Tesla is known for using NCA cathodes developed by Japanese company Panasonic. This type of cathode has higher energy density and is a low-cobalt option, but has been less adopted by the industry compared to the widely used nickel-cobalt-manganese (NCM) cathodes. Aside from that, South Korea's LG Energy Solutions (KRX:373220) supplies Tesla with batteries using nickel-cobalt-manganese-aluminum (NCMA) cathodes.
As mentioned, it wasn’t just lithium that saw prices climb in 2021 — cobalt doubled in price that same year, and although it has declined since then, the battery metal remains essential for many EV batteries. Most cobalt mining takes place in the Democratic Republic of Congo, which is often associated with child labor and human rights abuses, fueling concerns over long-term supply.
That said, not all Tesla’s batteries contain cobalt. In 2021, Tesla said that for its standard-range vehicles it would be changing to lithium-iron-phosphate (LFP) cathodes, which are cobalt- and nickel-free. At the time, the company was already making vehicles with LFP chemistry at its factory in Shanghai, which supplies markets in China, the Asia-Pacific region and Europe.
In April 2023, Tesla announced that it planned to use this type of cathode chemistry for its short-range heavy electric trucks, which it calls "semi light." The company is also looking to use LFP batteries in its mid-sized vehicles.
At the top of this year, Tesla made moves to produce LFP batteries at its Sparks, Nevada, battery facility in reaction to the Biden Administration's new regulations on battery materials sourcing, especially on those sourced from China. Reuters reports Tesla battery supplier CATL will sell idle equipment to the car maker for use at the plant, which will have an initial capacity of about 10 gigawatt hours.
What company makes Tesla’s batteries?
Tesla works with multiple battery suppliers, including Panasonic, its longtime partner, as well as LG Energy Solutions, the second largest battery supplier in the world. They supply the EV maker with cells containing nickel and cobalt.
China's CATL has been supplying LFP batteries to Tesla for cars made at its Shanghai plant since 2020. It’s also been reported that BYD Company (OTC Pink:BYDDF,SZSE:002594) is supplying Tesla with the Blade battery — a less bulky LFP battery — which the car manufacturer has used in some of its models in Europe. Additionally, BYD is set to work with Tesla on its battery energy storage systems (BESS) in China, with a plan to supply 20 percent of Tesla's anticipated BESS manufacturing capacity, with CATL expected to cover 80 percent. The factory will use the companies' LFP batteries.
How much lithium is in a Tesla battery?
How much lithium do Tesla batteries actually contain? That question is tricky because many factors are at play. Typically, it depends on battery chemistry, as demonstrated by the chart below, as well as battery size.
For example, the standard Tesla Model S contains about 138 pounds, or 62.6 kilograms, of lithium. It is powered by a NCA battery, which has a weight of 1,200 pounds or 544 kilograms.
The amount of lithium in a Tesla battery can also vary based on model and year as the battery chemistries and weights are often changing with each new iteration.
Back in 2016, Musk said batteries don't require as much lithium as they do nickel or graphite — he described lithium as "the salt in your salad." As the chart below shows, the metal only makes up about a 10th of the materials in each battery.
Metal content of battery chemistries by weight.
Chart via BloombergNEF.
But a key factor to remember is volume — given the amount of batteries Tesla needs to meet its ambitious goals, it could hit a bottleneck if it can’t secure a steady supply of raw materials. Of course, this is true not just for Tesla, but for every carmaker producing EVs today and setting targets for decades to come.
For that reason, demand for lithium-ion batteries is expected to soar in the coming years. By 2030, Benchmark Mineral Intelligence forecasts that demand will grow by 400 percent to reach 3.9 terawatt-hours. Over the same forecast period, the firm sees the current surplus in the lithium supply coming to end.
Will Tesla buy a lithium mine?
For carmakers, securing lithium supply to meet their electrification goals is becoming a challenge, which is why the question of whether they will become miners in the future continues to come up.
But mining lithium is not easy, and despite speculation, it's hard to imagine an automaker being involved in it, SQM’s (NYSE:SQM) Felipe Smith said. “You have to build a learning curve — the resources are all different, there are many challenges in terms of technology — to reach a consistent quality at a reasonable cost,” he noted. “So it's difficult to see that an original equipment manufacturer (OEM), which has a completely different focus, will really engage into these challenges of producing.”
Even so, OEMs are coming to the realization that they might need to build up EV supply chains from scratch after the capital markets' failure to step up, Benchmark Mineral Intelligence’s Simon Moores believes. Furthermore, automotive OEMs that are making EVs will in effect have to become miners.
“I don't mean actual miners, but they are going to have to start buying 25 percent of these mines if they want to guarantee supply — paper contracts won't be enough,” he said.
However, last year Musk made it clear to investors that Tesla is more focused on developing its lithium refining capabilities, rather than getting into the mining game.
Where is Tesla's lithium refinery?
Tesla broke ground on its in-house Texas lithium refinery in the greater Corpos Christi area of the state last year. Tesla's lithium refinery capacity is expected to produce 50 GWh of battery-grade lithium per year. Musk said in late 2023 that construction of the lithium refinery would be completed in 2024, followed by full production in 2025.

Laguna Verde Operational Update
CleanTech Lithium PLC (AIM: CTL, Frankfurt:T2N, OTCQX:CTLHF), an exploration and development company advancing sustainable lithium projects in Chile, provides an operational update on progress with the Laguna Verde pre-feasibility study ("PFS"), the 2024 exploration programme and Direct Lithium Extraction ("DLE") pilot plant process work to produce battery-grade lithium carbonate.
Highlights:
Laguna Verde PFS Update
- Location of preferred sites for carbonation plant in Copiapó and port facilities for export of final lithium carbonate product have been selected
- Power supply study completed evaluating options for onsite renewables which provides a competitive alternative to the base case of a transmission line and grid connection
- Option to utilise electric truck transport identified, lowers emissions and noise pollution, and by hauling from high to low altitude regenerative charging reduces power consumption
- Decision to configure project based on locating DLE plant at Laguna Verde and carbonation plant in Copiapó has numerous advantages contributing to a more robust PFS
- Engineering for this configuration has extended the expected PFS delivery to Q1 2025
Exploration Programme and Pilot Plant Updates
- Results from two completed wells and pump tests for the 2024 field programme have been received increasing knowledge of the resource and providing additional information for the hydrogeological model
- Downstream processing work from our pilot plant is progressing well with lithium carbonate production expected in November
Investor webinar
- CTL to host investor webinar on Tuesday 5th November at 17:00 GMT. Register here: https://www.investormeetcompany.com/cleantech-lithium-plc/register
Steve Kesler, Executive Chairman and Interim Chief Executive Officer, CleanTech Lithium PLC, said:
"With the recent announcement by the Chilean Government to prioritise six salt flats, including Laguna Verde, to start the process of awarding Special Operating Lithium Contracts (CEOLs), we are focused on the key aspects to advance the project, being permitting, completion of the PFS and production of battery grade lithium carbonate from our pilot plant.
Progress has continued on central elements of the PFS with evaluation of plant location, power supply and transport options. As a leader in developing DLE based projects in Chile, we aim to enter production in 2027 when the lithium market is expected to rebalance, providing a strong long term growth outlook."
Further Information
Sites Selected for Carbonation Plant and Port for Export of Final Product
As part of the ongoing PFS for the Laguna Verde project, a trade-off analysis was completed which determined the DLE plant and eluate concentration stages should be located at the Laguna Verde site, and the carbonation plant at the nearby mining centre of Copiapó. This was reported to the market on July 2, 2024. The re-configuration required a change in pre-engineering design provided by Lanshen Technology, the Company selected to provide the lithium processing plant design and equipment. This has extended the expected PFS completion, which was originally targeted for Q4 2024, into Q1 2025.
The Company has since undertaken studies to determine the ideal location of the carbonation plant in Copiapó and selected a site. After evaluating several options, a site in an industrial zone which by-passes to the south-east of Copiapó was chosen, as shown in Figure 1. This location has existing power and water supply options and provides a direct route to port.
Figure 1: Carbonation Plant Location Map
Figure 2: Carbonation Plant Design Layout
A trade-off analysis was undertaken to evaluate transport corridors and port facilities providing four different options for export of final lithium product. The study indicated that the nearby Caldera Port provides the most suitable option either utilising existing infrastructure which is currently utilised for seasonal shipment of agricultural products, shown in Figure 3. Other port options are also available and may come into consideration however Caldera Port is the current preference.
Figure 3: Caldera Port Existing Facilities
Power Supply Alternative of Onsite Renewable Generation
The Company engaged Chilean consultant Clean Power Hunters to undertake a power supply study to evaluate the option of using renewable power generated at the project site as an alternative to the base case of a transmission line and grid connection. Laguna Verde is located in the region with the highest solar irradiance in the world, as shown in Figure 4. Analysis of estimated Capex and Opex was provided based on different configurations of onsite renewables, either solar plus a battery energy storage system (BESS) or solar plus wind plus BESS. Figure 5 shows the lowest Capex corresponds to combining solar with three wind turbines plus BESS.
Figure 4: Solar Irradiance Map
Figure. 5: Solar + Wind + BESS Scenarios Capex Split
The Company has received proposals including from major global solar plus BESS suppliers, consistent with the costs estimated in the study and competitive with the grid connection option. The financing model for both the grid connection model or the alternative of onsite renewables is expected to be based on a power purchase agreement and a build own operate basis by established suppliers. These proposals will be built into the PFS and the commercial analysis of the project.
Truck Transport Study
Based on the outcome of the plant location study the Company will transport 6% Li in solution post the DLE and concentration stages at Laguna Verde to the carbonation plant. Use of standard and electric trucks is being compared with the latter providing several potential benefits in addition to cutting CO2 emissions. Electric trucks are well suited to hauling loads from high to low altitudes by taking advantage of regenerative charging to reduce power consumption and required battery capacity. Minimal noise and elimination of tailpipe emissions is particularly attractive considering the transport route traverses an indigenous community settlement approximately 100km from the project site, a community the company has been working with closely.
The Company has gathered insight from several potential suppliers. Chinese company XCMG is a leader in electric trucks and is actively expanding its offering in Chile, with its E7-49T model which has a haulage load of 49 tonnes potentially providing a suitable option. The technology is evolving rapidly and is expected to provide a strongly cost competitive option in line with the project development timeline.

2024 Exploration Programme Update
CleanTech Lithium´s 2024 drilling programme anticipated to drill five new resource wells, as shown in Figure 8, with the aim of upgrading the existing Measured and Indicated resource into maiden Reserves for the Laguna Verde project. The existing JORC compliant resource estimate of 1.8 million tonnes of lithium carbonate equivalent (LCE) is based on six wells completed in 2022 and 2023. The Company engaged Montgomery & Associates Consultores Limitada ("Montgomery" or "M&A"), a leading hydrogeological consultant, for the programme. During 1H 2024, two of the five resource wells were completed being LV07 and LV11, along with three observation wells drilled to support observations during pumping tests, before winter conditions curtailed the programme in June 2024. The full 2024 programme is paused until further funding is available following the Company´s planned ASX fund raising and as a result Montgomery has produced an interim report on work completed.
Figure 8: Laguna Verde Drilling Wells Map - Show original figure
Drilling activities for exploration borehole LV07 reached a final depth of 650m below land surface. This well was drilled with PQ3 diameter from land surface to 300m, and with HQ3 diameter from 300m to 650m. Packer samples were obtained during drilling for 2-meter packer intervals and the volume of the well was purged at least one time before obtaining the sample. Assuming a lithium cut-off grade of 100 mg/L, the average lithium grade of the packer samples corresponds to 139 mg/L with the well encountering lower density water in the upper 150m.
In contrast to LV07, drilling at LV11 did not reach the anticipated depth due to the presence of hydrothermal waters (under pressure) which were encountered during drilling, with a final depth of 412.8m below land surface. Assuming a lithium cut-off grade of 100 mg/L, the average lithium grade of the packer results would correspond to 131 mg/L. In general, it is believed that lithium grades decrease below 220m at LV11 due to the presence of dilute hydrothermal waters which were encountered during drilling. The presence of hydrothermal waters in the eastern portion of the Project are more dilute than the average lithium grade measured in other exploration wells.
Figure 9: Drilling at LV07 in 1H 2024
Lithology and Drainable Porosity
Based on core retrieved from drilling, the most predominant lithology encountered corresponds to a volcanic tuff with variable levels of consolidation and welding based on the depth and location. As determined by relative brine release testing at Geosystems Analysis (GSA) laboratory in Tuscon, USA, drainable porosity values of collected core samples from LV07 and LV11 range from 0.3% to 9.2%, with an arithmetic average of approximately 4%; this is considered by Montgomery to be reasonable for the encountered lithologic units based on visual inspection of the core.
Figure 10: Example of Drill Core from Exploration Borehole LV11 (132 to 136m)
Hydrogeological Evaluation
In addition to resource drilling, the 2024 campaign aimed to complete pump tests to evaluate the feasibility of lithium brine extraction for the Project and to also estimate aquifer parameters. Prior to the winter break, three observation wells were completed and initial variable rate step tests and a constant rate flow test undertaken. The intended long duration pump tests at well LV05 was not able to be completed, however a 7-day pumping test was successfully completed at LV06. With data obtained to date, Montgomery is able to continue refining the hydrogeological modelling that will feed into the design of the extraction and reinjection well fields for the PFS. A key aspect is to ensure no impact on surface water bodies.
Recommendations and Next Steps
Based on the obtained results from the 2024 exploration programme, recommended priorities for continued exploration include additional drilling and testing in the western portion of the Project concessions. A long-term pump test at LV05 (as part of the planned reinjection test) will also aid in demonstrating feasible extraction and reinjection to the west of the basin. A long-term test at LV05 will also allow for a better understanding of the hydraulic connection between the deep and shallow aquifers in that area.
On the completion of the 5 well programme as originally planned for 2024, the existing JORC compliant resource estimate of 1.8 million tonnes will be updated and a Reserve estimate will be calculated for the project. The Reserve calculation is the economically mineable part of the Measured and/or Indicated resource and this will be defined by the PFS data demonstrating that extraction could reasonably be justified. Progress continues on the PFS and the remaining planned wells will be completed as funds are available following completion of the planned ASX capital raising.
Pilot Plant Update
Downstream conversion of concentrated eluate from the Company´s pilot plant into battery grade lithium commenced last week at the facilities of Conductive Energy in Chicago, USA. The initial volume of 88m3 of concentrated eluate from Laguna Verde, equal to approximately one tonne of lithium carbonate equivalent ("LCE"), will be processed in four batches with the first batch expected to produce a volume of battery-grade sample product in November. With this product, the Company plans to engage with strategic partners for product qualification.
