Battery and critical metals explorer and developer Pan Asia Metals Limited (ASX: PAM) (‘PAM’ or ‘the Company’) is pleased to provide an update for new drill holes (BTDD022-025) completed at the Bang I Tum prospect. Drilling results continue to support the geological model applied to the Exploration Target estimate with lithium mineralisation hosted in mica (lepidolite and/or muscovite) rich pegmatite dykes-veins and adjacent metasediments. The prospective zone is currently defined over a strike length of over 1km and remains open along strike and at depth on many sections.
HIGHLIGHTS
- Visual results for holes (BTDD022-025) continue to demonstrate substantial extensions of the pegmatite dyke swarm at Bang I Tum.
- Results indicate pegmatite dyke-vein swarm is over 300m wide in the northern portion.
- Drilling confirms discovery of new pegmatite zones to the west of the main zone with pegmatites intersected down-dip of elevated lithium in rock-chips and soils at surface.
- Drilling confirms further northern extensions of the Main zone in association elevated lithium in rock-chips and soils at surface.
- Pegmatite geometries are consistent with geological interpretation for the current Exploration Target of 8-14Mt @ 0.5-0.8% Li2O1.
- Updated Exploration Target estimate is currently being prepared and will include new Western Zone.
- Drilling is ongoing with the aim of reporting a Mineral Resource Estimate for the Bang I Tum Lithium Prospect later in 2023.
- Metallurgical testwork samples from Bang I Tum are being prepared.
Pan Asia Metals Managing Director said: “Visual observations in the drilling to date show substantial extensions to the mineralised zone, with the pegmatite dyke swarm over 300m in width in certain areas. In comparison, Reung Kiet has a dyke swarm width of about 100m at the southern end of that Prospect. Assay results to date are very encouraging, as are visual observations. Drilling continues and we are currently considering a third rig, a decision will be made with a 3rd Quarter start in mind. Overall we are very pleased with the results at Bang I Tum, the prospect is shaping up well.”
1The potential quantity and grade of the Exploration Target are conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
The Reung Kiet Lithium Project (‘RKLP’), inclusive of the Bang I Tum prospect is one of PAM’s key assets. RKLP is a hard rock lithium project with lithium hosted in lepidolite/muscovite rich pegmatites chiefly composed of quartz, feldspar, lepidolite and muscovite, both lithium bearing micas, with minor cassiterite and tantalite as well as other accessory minerals. Previous open pit mining extracting tin from the weathered pegmatites was conducted into the early 1970’s.
Bang I Tum Lithium Prospect
The Bang I Tum Lithium Prospect (Bang I Tum or BIT), is located about 8km north of the Reung Kiet Lithium Prospect in southern Thailand. At Bang I Tum PAM has estimated a drill supported Exploration Target of 8 to 14 Million tonnes at a grade ranging between 0.5% to 0.8% Li2O (see PAM ASX announcement “Reung Kiet Lithium Project Exploration Target” dated 27 July, 2022). Grades were also estimated for Sn, Ta2O5, Rb, Cs and K, see Table 1.
Table 1. RKLP – Bang I Tum Prospect - Exploration Target, 27 July, 2022
The BIT prospect hosts a significant historic tin mine that extends for almost 2km along strike. Mining was undertaken by open cut hydraulic methods to about 40m below surface and ceased when hard rock was intersected.
Further mapping and soil and rock-chip sampling has significantly increased the exploration potential at Bang I Tum immediately west of the existing Exploration Target. This new Western zone, approximately 800m long and 200m wide, is characterized by numerous mica rich alpo-pegmatite dykes and veins that are interpreted to be a westerly extension of the dyke swarm and the existing Exploration Target (see PAM ASX announcement “Bang I Tum – High Grade Lithium Results” dated 24 October, 2022. Recent drilling has provided additional support for this zone. Pan Asia is currently preparing an updated Exploration Target estimate that will include the new Western zone.
The BIT prospect is separate to the Reung Kiet Prospect where PAM has reported an inaugural Inferred Mineral Resource (see PAM ASX announcement “Inaugural Mineral Resource Estimate Reung Kiet Lithium Project” dated 28 June, 2022) as shown in Table 2. PAM retains a 100% interest in both prospects.

Nevada Lithium Significantly Increases the Size and Grade of Lower Zone Inferred Mineral Resources at Bonnie Claire to 25.634 Mt LCE at 3,085 ppm Li. Reports Maiden Indicated Resources of 5.167 Mt LCE at 3,519 ppm Li and 2.318 Mt B at 8,404 ppm Boron
Nevada Lithium Resources Inc. (CSE: NVLH; OTCQB: NVLHF; FSE: 87K) (“Nevada Lithium” or the “Company”) is pleased to provide an updated mineral resource estimate (“Mineral Resource Estimate”) at its 100% owned Bonnie Claire Lithium Project (the “Project” or “Bonnie Claire”), located in Nye County, Nevada. The Mineral Resource Estimate was prepared by Global Resource Engineering (“GRE”) in accordance with Canadian Institute of Mining and Metallurgy and Petroleum (“CIM”) definitions, as required under National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”) and has an effective date of September 24, 2024. Most notably, the Lower Zone (as defined below) gives an indicated resource of 275.85 million tonnes (“Mt”) at 3,519 parts per million (“ppm”) lithium (“Li”) (5.167 Mt lithium carbonate equivalent (“LCE”)) and 275.85 Mt at 8,404 ppm boron (“B”) (2.318 Mt B), together with an inferred resource of 1,561.06 Mt at 3,085ppm lithium (25.634 Mt LCE).
Nevada Lithium’s CEO, Stephen Rentschler, comments:
“We are excited to announce the impact of the new drilling in the Lower Zone of mineralized lithium and boron at Bonnie Claire. With the significantly increased tonnage and higher grades, Bonnie Claire is potentially unrivaled by other sediment hosted lithium projects in Nevada and is now amongst the largest lithium resources in the world and amongst the highest-grade in Nevada.
Compared to Bonnie Claire’s previous resource report, the new drilling in the Lower Zone has led to a 68% increase in LCE tonnage, at an average grade that has tripled from 1,000 ppm to over 3,000 ppm. It includes intervals where grades exceed 6,000ppm. These increases have occurred using a cut-off grade that has more than doubled to 1,800 ppm. For the first time, we are also able to report a significant high-grade boron resource that we believe further enhances the Project’s value.
The Lower Zone remains open to the NW, NE and SE, for future resource expansion. Furthermore, the new infill drilling has resulted in an indicated resource classification. We are confident that the continuity of the mineralization will allow us to easily upgrade additional resources from the inferred classification into indicated resources and add new inferred resources.
The results from this report will feed directly into ongoing work on an updated Preliminary Economic Assessment (“PEA”) that we are targeting for completion at the end of Q1 2025. This PEA will reflect the increased tonnages and grades reported today. The PEA will also include the metallurgical processes currently being developed by Fluor Enterprises Inc., as reported in our news release dated October 23, 2024.
I would like to offer my congratulations and thanks to Nevada Lithium’s technical team for this tremendous success. Their dedication and vision has led to results that are of global significance and, in my opinion, will lead to future increases in shareholder value.”
Highlights:
- Resources for the deposit have been separated into two zones; a Lower Zone (i.e., mineralization hosted by Lower Claystone and Lower Sandstone units) (the “Lower Zone”) and an Upper Zone (i.e., mineralization hosted by an Upper Claystone unit) (the “Upper Zone”).
- The updated Mineral Resource Estimate includes assays from eleven (11) additional exploration and infill drill holes completed since the 2021 maiden resource estimate. 2023 & 2024 drilling intersected the lower claystone which hosts the high grade (up to 7,160ppm) lithium, and which remains open in three directions. It is reasonably expected that the bulk of inferred resources can be upgraded to indicated through additional infill drilling.
- The Lower Zone gives an indicated resource of 275.85 Mt at 3,519 ppm lithium (5.167 Mt LCE) and 275.85 Mt at 8,404 ppm Boron (2.318 Mt B), together with an inferred resource of 1,561.06 Mt at 3,085ppm lithium (25.634 Mt LCE). This base-case resource is based on a 1,800ppm lithium cutoff, constrained by hydraulic borehole mining (“HBHM”) parameters, and an assumed 60% recovery of the host strata.
- The Upper Zone gives an indicated resource of 188.08 Mt at 1,074 ppm lithium (1.075 Mt LCE) and 152.11 Mt at 1,519 ppm boron (0.231 Mt B), together with an inferred resource of 451.10 Mt at 1,106 ppm lithium (2.655 Mt LCE) and 270.53 Mt at 1,505 ppm boron (0.407 Mt B). This resource is calculated at a 900 ppm lithium cut-off, within a constraining pit shell, and would be mined by conventional open-pit methods
- The 60% HBHM recovery is based purely on a cylindrical cavity and does not account for any improved recoveries from the expected plastic deformation of the deep zone material.
- The updated Mineral Resource Estimate will be included into ongoing work on an updated PEA expected for completion at the end of Q1 2025.

Results and Interpretation
Bonnie Claire consists of a sedimentary package of volcaniclastic origin, laid down in a NW-SE basin striking basin. Lithium and boron mineralization are located within an Upper Zone, hosted within an upper claystone unit encountered by drilling from surface to about 425 ft (130m), and a Lower Zone, hosted within lower claystone and lower sandstone units intersected from 1,500-2,850ft (457-853m). Lithium mineralization appears to be hosted within non-swelling clay phases such as illite, or as lithium carbonate or salt within the sedimentary matrix. Boron mineralization appears to be associated with searlesite, a sodium borosilicate mineral.
While the Upper Zone and Lower Zones exhibit lithium and boron mineralization, they are separated spatially, and exhibit differences in metallurgical behaviour, leading the Company to treat them as two distinct deposits with different mining methods.
Lower Zone
While early exploration concentrated on mineralization in the Upper Zone, the Company has shifted its focus to mineralization in the Lower Zone, hosted in the lower claystone and sandstone units and containing the bulk of lithium and boron. This Lower Zone remains open to the NW, NE and SE. The current plan is to use an underground HBHM method, with a higher 1,800ppm cut-off. The Mineral Resource Estimate for the Lower Zone is presented in Table 1-1 and the sensitivity of the Lower Zone to cutoff grade is presented in Table 1-2.

Cautionary Statements Regarding Mineral Resource Estimates:
Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources will be converted into mineral reserves. Inferred mineral resources are that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. It is reasonably expected that the majority of inferred mineral resources could be upgraded to indicated mineral resources with continued exploration.
Resource Estimation Parameters
The updated Mineral Resource Estimate for Bonnie Claire was performed using Leapfrog® Geo and Leapfrog® Edge software. Leapfrog® Geo was used to update the geologic model, and Leapfrog® Edge was used for geostatistical analysis and grade modeling in the block model. An oblique view of the block model at Bonnie Claire is illustrated by Figure 1.1
Figure 1.1: Oblique view from southwest of block model for Bonnie Claire generated by Leapfrog® Edge software. Lithium ppm legend to right.
The drill hole database used for the estimation included:
- 21 exploration drill holes, including 8 reverse circulation holes and 11 vertical diamond core holes
- 9,159.54 meters of drilling in exploration drill holes
- 1,898 assay intervals in exploration drill holes
- Minimum grade of 18 ppm Li in exploration drill holes
- Maximum grade of 7,160 ppm Li in exploration drill holes
Cumulative probability plots of lithium and boron assay values did not exhibit grade breaks that would indicate the presence of outlier data, so the data were not capped or clipped. A specific gravity of 1.7 grams per cubic centimeter (g/cm3) for all lithological units, comparable to other similar lithium deposits. Drill hole assay values were composited to intervals of equal length to ensure that the samples used in statistical analysis and estimations were equally weighted. The majority of samples were collected at 6.096-meter (20-foot) intervals, with some samples collected at other intervals up to a maximum of 12.192 meters (40 feet). Down-the-hole composites were created from the Li and B assays within upper claystone, lower claystone, and lower sandstone mineralized domains, with the following specifications: 6.096-meter (20-foot) intervals, with anything less than 3.048 meters (10 feet) added to the previous interval. This resulted in 1,313 Li composite intervals with Li grades from 40.37 ppm to 5,764.48 ppm and 857 B composite intervals with B grades from 10 ppm to 14,658.8 ppm.
Qualified Person Terre Lane estimated Li and B grades into the block model using inverse distance to the second power (“ID2”) and for each method, a single pass was conducted at the ellipsoid ranges (1,600 meters x 900 meters x 150 meters). All blocks with modeled grade were coded as inferred resources. The search was restricted to a minimum of four samples and a maximum of 12 samples per block and a maximum of three samples per drill hole, thereby requiring data from a minimum of two drill holes to populate a block. For statistical comparison, nearest neighbor (“NN”) and ordinary kriging (“OK”) models were run to serve as comparisons with the estimated results from the ID2 method. The estimate means for the global population as well as the means for the estimation domains are similar, suggesting the ID2 estimate is not biased or overestimating the grades. The reduction in mean, coefficient of variation, and maximum from composites to the ID2 estimate shows an appropriate amount of smoothing. Swath plots and visual comparison of composites versus block model values by section and plan show good correlation.
Mining Methods
Hydraulic Borehole Mining of Lower Zone
As disclosed in their April 16, 2024, news release, Nevada Lithium contracted Kinley Exploration LLC (“Kinley”) to provide a preliminary evaluation of HBHM for Bonnie Claire.
Kinley was asked to establish a reasonable and economic mining strategy utilizing HBHM within the Bonnie Claire Lithium resource deposit to extract lithium in a continuous, efficient, cost effective and safe manner in the targeted higher grade zone from 1,500-2,800ft (457-853m) deep.
Kinley’s analysis took into consideration that the mineralization is highly plastic and with the assistance of jetting and pumping would likely flow. With this information, coupled with the significant cost of backfilling and then the consideration of subsidence, Kinley evaluated HBHM without backfilling and using directional drilling from a stable position.
The Kinley model assumed the highly mobile mineralization within the target section would behave plastically and flow in a fluid state or caving condition to the mining system intake. This relies on flow of the mobilized mineralization, accelerated by high pressure jetting to a centralized well, then pumped back to surface. GRE assumes a more conservative recovery of 60% because of potential mass flow issues that need to be evaluated during test mining.
Open Pit Mining of Upper Zone
Open pit mining of the Upper Zone at Bonnie Claire would likely use conventional mining equipment of hydraulic shovels and mining haul trucks but could possibly use scrapers. The soil is extremely soft and typically saturated. As a result, pit wall slopes would need to be relatively shallow; for the Lerchs-Grossman pit exercise in Section 14, the GRE Qualified Person used 18° side wall slopes. Additional geotechnical testing would need to be completed to determine stable side wall slope angles, bench heights, and catch bench widths. Dewatering portions of the pit, freezing, or other forms of stabilizing pit slopes and bottom may be required.
Mineral Processing and Metallurgical Testing
The mineral assemblage changes with depth. The Upper Zone generally shows lower grade lithium and boron and higher calcite content, while the Lower Zone tends to be significantly higher-grade lithium and boron and lower calcite content. The final mine design has not been completed, and the project may have several options: mine the upper portion, mine the lower portion, or mine the entire deposit. As a result, two distinct treatment options have been evaluated.
For the Upper Zone, a thermal treatment was developed that involved a sulfate calcination followed by a hot water leach. This process had the advantage of not solubilizing as many impurities, particularly iron. High lithium extractions (up to 80%) were achieved.
New drill samples from the Lower Zone were tested, and the calcination process was not effective due to the low melting point of the boron minerals (searlesite). Subsequently, sulfuric acid leaching was evaluated to treat the deeper deposit material. The acid treatment demonstrated that the lithium host is readily soluble in a strong sulfuric acid solution, achieving extractions of approximately 85%. The conventional downstream purification of the acid liquor had challenges for the upper sections of the deposit due to high iron solubilization.
Boron concentrations in the Lower Zone warrant a separate boron recovery circuit. Boron is recovered from the leach liquor after primary impurity removal via ion exchange to produce a boric acid product.
Quality Assurance / Quality Control
A quality assurance / quality control protocol following industry best practice was incorporated into the drill program by Nevada Lithium. Drilling was conducted by Major Drilling Group International Inc. (“Major Drilling”). Core was transported by Major Drilling from the collar location and received by Nevada Lithium staff at the Company storage facility in Beatty, Nevada. The facility is only accessible to Nevada Lithium staff and remains otherwise locked. Received core was logged and cut at the facility by Nevada Lithium staff. Logging and sampling included the systematic insertion of blanks, duplicates and certified reference material (“CRM”) MEG Li.10.12 and OREAS 750 into sample batches at an insertion rate of approximately 10%. All core samples collected were transported by Company staff to ALS USA Inc.’s laboratory in Reno, Nevada. for sample preparation. Sample preparation comprises initial weighing (Code WEI-21), crushing quality control test (CRU-QC), pulverizing quality control test (PUL-QC), fine crushing at 70% <2mm (CRU-31), sample split using Boyd rotary splitter ((SPL-22Y), pulverizing up to 250g 85% <75 µm (PUL-31), crush entire sample (CRU-21), pulp login (LOG-24) and a crusher wash (final crusher wash between samples (WSH-21). Samples were shipped to ALS USA Inc.’s Vancouver laboratory in Burnaby British Columbia, where the samples were analyzed using 48-element four-acid inductively coupled plasma mass spectrometry (ME-MS61) and B/Li N₂O₂ fusion inductively coupled plasma atomic emission spectroscopy high-grade (ME-ICP82b) procedures.
Data verification by GRE staff included: an on-site inspection of the Project site and core, reverse circulation and chip tray storage facilities, check sampling, geologic maps and reports, and manual auditing of the Project drill hole database. GRE’s Qualified Persons have been involved with the project since 2018. They visited the site in 2018 after drilling, during drilling in 2020 and 2022. The results from the site inspection, visual sample inspection and check sampling for each drilling campaign are given below. Based on the results of GRE’s Qualified Persons check of the sampling practices, verification of drill hole collars in the field, results of the check assay analysis, visual examination of selected core intervals, and the results of both manual and mechanical database audit efforts, GRE considers the collar, lithology, and assay data contained in the project database to be reasonably accurate and suitable for use in estimating mineral resources.
The data verification of the drilling campaigns shows that data from the rotary mud drilling was suspect and not used in the resource estimate. Open pit mining and processing methods, costs and infrastructure needs were verified by Ms. Lane in comparison to other similar sized open pit mines operating in the western USA. Borehole mining costs were developed by Kinley with coordination with GRE. Other cost data used in the report was sourced from the most recent infomine cost data report. All costs used to determine reasonable prospects for economic extraction were verified and reviewed by GRE and were assessed to be current and appropriate for use.
Metallurgical testing was completed for Bonnie Claire by a well-known commercial metallurgical laboratory. GRE reviewed all available metallurgical reports. GRE confirmed that the mineralization found at the Project is similar to another project where GRE has performed other consulting work and finds that the test work for Bonnie Claire shows that the material behaves in a similar manner, specifically in lithium extraction and recovery and reagent consumption. Given the similarities of the Bonnie Claire material to other similar projects, this provides a good basis for benchmarking the metallurgical test. The work appears to be professionally completed and is well documented and is suitable for estimation of lithium extraction and recovery calculations in the Mineral Resource Estimate.

Warrego East Drilling Permitted as Takeover Action Underlines Prospectivity of Tennant Creek Mineral Field
- The $82M takeover of Tennant Creek Mining Group Pty Ltd (TCMG) by London-listed Pan African Resources PLC (AIM: PAF) has reignited interest in the underexplored Tennant Creek Mineral Field (TCMF)1
- The corporate activity comes as Metal Australia finalises plans for a substantial exploration program at its Warrego East copper-gold project2 after the Northern Territory Government authorised the Company’s Mine Management Plan. Warrego East is adjacent to, and immediately east of, the high- grade Warrego mine and Mineral Resource held by TCMG and its Joint Venture partner, Emmerson Resources (ASX: ERM)3
- The program will test a series of priority gravity and magnetics defined ironstone hosted copper- gold targets within a corridor which links the Warrego mine with the Gecko and Orlando copper- gold deposits4,5. The Warrego mine historically produced 4.95Mt @ 2.0% Cu and 8g/t Au6
- Weather permitting, the field exploration program will commence as soon as land holder access agreements are finalised.
Metals Australia CEO Paul Ferguson commented:
“We welcome the clear show of confidence Pan African Resources has demonstrated in the Tennant Creek Mineral Field via its $82 million takeover of TCMG, which is Emmerson Resources’ JV partner in the tenements hosting the Warrego copper-gold mine and various mineral resources. This comes as Metals Australia finalises plans for a substantial field exploration program at its Warrego East copper-gold project, located immediately adjacent to and east of those JV tenements.
The takeover of TCMG by Pan African Resources demonstrates the potential now being seen by bigger overseas players in the Tennant Creek Mineral Field. With a market cap of more than $1 billion, South African- based Pan African Resources has recognised the potential of this underexplored region to host significant mineral resources where less than 10% of drilling has extended beyond 150m in depth and where almost all significant deposits to date have been discovered under shallow cover.
The Warrego mine was identified undercover as a magnetic anomaly during an airborne survey conducted in 1956. Similar magnetic anomalies occur within a corridor through our Warrego East lease, with the Gekko and Orlando deposits discovered further to the east, within the same corridor.
Warrego went on to produce consistently between the early 1970s up until 1989 – averaging around 2% copper and 8gpt of gold during its production life.
We are working diligently to finalise the remaining requirements for our upcoming exploration program at Warrego East.
The planned program is a further illustration of Metals Australia’s status as one of the most active exploration companies, with field exploration programs recently completed at three projects and two more in the pipeline as we seek to unlock the true value of our portfolio in known mining districts in Australia and Canada.”
Figure 1: Metals Australia’s Tenements, TCMG tenements (acquired by PAF), Warrego Production6 in the TCMF.
This comes as the prospectivity of the Tennant Creek Mineral Field is further underlined by the $82 million takeover of TCMG announced on 5 November. Metals Australia’s Warrego East project is adjacent to, and immediately east of, the tenements hosting the Warrego mine and mineral resources held by TCMG and its JV partner Emmerson Resources.
The Tennant Creek Mineral Field has produced 25Mt @ 6.9 g/t gold (Au) & 2.8% copper (Cu)4, with historical production coming from deposits in outcropping areas – or undercover - such as the Warrego mine. Metals Australia’s tenements are located on Cu-Au trends in areas of shallow soil cover which have not been tested with modern exploration (see Figure 2 below). The tenements include EL32725 (granted) and EL32837, EL32937 and EL32410 (all under application), which were acquired by the Company as part of its 80% acquisition of Payne Gully Gold7 in 2022.

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.

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.

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.
