From Pilgangoora to Kathleen Valley: Understanding Lithium Stocks ASX Investors Follow
The Australian lithium sector sits at an important point in the global battery supply chain.
Western Australia is one of the world’s leading sources of hard-rock lithium, particularly spodumene concentrate. This material is shipped to chemical processing centres, mainly in China and South Korea, where it is converted into lithium hydroxide or lithium carbonate for use in electric vehicle batteries and energy storage systems.
After the sharp lithium price increases seen during 2022 and 2023, the market went through a difficult period. Temporary oversupply, slower electric vehicle adoption and high processing costs placed pressure on producers and developers.
That has made the discussion around the best lithium stocks ASX investors can follow more complicated. Production scale is important, but it is not the only factor. Costs, cash reserves, project quality, processing arrangements and customer agreements also matter.
This article looks at several major lithium stocks ASX investors regularly monitor, including PLS Group, IGO, Mineral Resources and Liontown Resources.
How the Australian lithium sector works
Most Australian lithium production comes from hard-rock mining rather than brine extraction.
In a hard-rock operation, lithium-bearing ore is mined, crushed and processed to produce spodumene concentrate. The concentrate is usually graded at around 6% lithium oxide, which is why it is often referred to as SC6.
The concentrate is then exported to chemical conversion plants. These facilities produce battery-grade lithium chemicals, which are used in electric vehicles, grid-scale batteries and other energy storage products.
China remains a major part of this supply chain. It processes more than 60% of the world’s lithium, meaning prices for lithium carbonate and lithium hydroxide in China can have a direct impact on the prices Australian producers receive for exported spodumene.
This is one reason ASX lithium stocks can be affected by global developments even when their mines are located in Western Australia.
The market is also changing because of the growth of energy storage systems. Electric vehicles remain an important source of lithium demand, but utility-scale storage projects are becoming more significant. Many of these systems use lithium iron phosphate, or LFP, battery cells.
The increase in LFP storage demand could provide another source of long-term demand for lithium chemicals.
PLS Group Limited (ASX: PLS)
PLS Group, formerly known as Pilbara Minerals, operates the Pilgangoora project in Western Australia’s Pilbara region.
Pilgangoora is a large hard-rock spodumene operation and is the main asset behind the company’s position in the lithium market.
The company’s expansion plans include the P680 project and the longer-term P1000 target. The P1000 expansion is designed to support production of up to approximately one million tonnes of spodumene concentrate each year.
Production scale is one of the main features of PLS. A larger operation can spread some costs across greater volumes, although it also requires significant infrastructure and capital investment.
The company has also maintained a net cash position, according to the supplied sector information. A strong cash position can give a producer more flexibility during periods of weaker lithium prices and may reduce the need for highly dilutive capital raisings.
Another important part of the PLS story is its partnership with POSCO. The joint venture provides exposure to lithium hydroxide refining in South Korea, giving PLS a connection to the downstream part of the battery supply chain.
For people researching best lithium stocks, PLS is often included in the discussion because it combines a large resource, established production and downstream exposure.
That does not remove the risks. Revenue is still linked to lithium prices, while expansion projects can face higher construction costs, delays and changing market conditions.
IGO Limited (ASX: IGO)
IGO provides exposure to the Greenbushes lithium mine through the Tianqi Lithium Energy Australia joint venture.
Greenbushes is widely recognised as one of the highest-grade and lowest-cost hard-rock lithium deposits in the world. The joint venture structure includes IGO and Tianqi Lithium.
The mine supplies spodumene feedstock, while the broader arrangement also includes the Kwinana lithium hydroxide refinery in Western Australia.
Cost position is an important factor when comparing lithium stocks ASX investors are researching. A low-cost operation may be better placed to continue producing when commodity prices fall, although no producer is completely protected from a long downturn.
Greenbushes has historically been known for its cost advantages. This gives IGO exposure to a mine that sits near the lower end of the industry cost curve.
The Kwinana refinery adds another layer to the company’s operations. Refining lithium hydroxide in Australia allows the business to participate further along the supply chain instead of focusing only on mining and exporting concentrate.
However, downstream processing can also be more complex. Refinery performance, operating costs and production consistency all affect the overall result.
IGO therefore represents a different type of lithium exposure from an early-stage explorer. Its position is connected to an established mine, a joint venture arrangement and a refining operation.
Mineral Resources Limited (ASX: MIN)
Mineral Resources has exposure to lithium through its interests in the Mt Marion and Wodgina operations in Western Australia.
Unlike a company focused only on lithium, Mineral Resources also operates across iron ore and mining services. This creates a more diversified business structure.
Diversification can change the way a company responds to commodity cycles. If lithium prices weaken, earnings from iron ore or mining services may influence the overall financial result. At the same time, investors need to understand that exposure to several industries can make the business more difficult to assess.
Mt Marion and Wodgina provide Mineral Resources with a position in hard-rock spodumene production. The company’s mining services operations also give it experience in extracting and moving materials at a large scale.
For anyone comparing the best lithium stocks ASX companies, Mineral Resources is an example of a diversified mining group rather than a pure lithium producer.
Its performance can be influenced by lithium prices, iron ore prices, production levels, project costs and conditions in the mining services market.
Liontown Resources Limited (ASX: LTR)
Liontown Resources has recently moved from developer to producer through its Kathleen Valley project in Western Australia.
Kathleen Valley is a large underground hard-rock lithium operation. The transition from construction and development into production is an important stage for any mining company.
Developing a mine is very different from operating one. Once production begins, investors and the market can assess actual mining rates, processing performance, costs and shipment volumes.
The project is also supported by multi-year offtake agreements with automotive and battery technology companies. Offtake agreements can provide a level of customer visibility, although the details of pricing, volumes and contract conditions still need to be considered.
Liontown’s underground mining approach gives the project a different operating profile from open-pit lithium mines. Underground mining can involve different development requirements, equipment needs and cost pressures.
The next stage will involve understanding how Kathleen Valley performs as production becomes more established.
This is why ASX lithium stocks should not be compared only by resource size. A company moving into production faces different questions from one still completing exploration or feasibility studies.
What to examine when comparing lithium stocks
The phrase best lithium stocks can mean different things to different investors. Some people focus on production growth, while others look at costs, balance sheets or exposure to downstream processing.
Several measures can help provide a clearer picture.
C1 cash cost
C1 cash cost measures the direct cost of producing and transporting a tonne of concentrate. It usually includes mining, processing, transport and site administration.
The supplied information identifies a C1 cash cost below US$600 per tonne as a useful long-term reference point. This should not be treated as a fixed rule for every operation, but lower costs generally provide more protection when prices soften.
All-in sustaining cost
All-in sustaining cost includes a wider range of expenses, such as royalties, sustaining capital expenditure and freight.
Comparing AISC with the prevailing spodumene price can help show whether a project is generating enough cash to maintain its operations.
Grade and recovery
The lithium oxide grade shows how much lithium is contained in the ore. Higher grades can reduce the amount of material that needs to be processed.
The brief identifies grades above 1.3% lithium oxide and recovery rates above 65% to 70% as useful reference points. Actual results vary from project to project.
Balance sheet and liquidity
Lithium prices can remain weak for longer than expected, so cash reserves matter.
When reviewing lithium stocks ASX companies, it is worth looking at debt levels, upcoming capital commitments, undrawn facilities and the company’s liquidity runway.
A company with large expansion plans may need additional funding even if it has a valuable resource.
Infrastructure and offtake arrangements
A mine’s location is only one part of the story. Access to roads, railways, ports and processing facilities can have a major impact on freight costs.
For Western Australian producers, access to infrastructure around ports such as Port Hedland or Geraldton can be relevant.
Offtake agreements also deserve attention. Investors can examine who the counterparty is, whether the agreement is based on spot prices, and whether it includes floor or ceiling pricing arrangements.
