Lake Johnston Project Update

Charger Metals NL (ASX: CHR, “Charger” or the “Company”) is pleased to announce further high- grade lithium intersections from the final assays of its maiden drill programme at the Medcalf Prospect of the Lake Johnston Lithium Project, Western Australia.


  • All assays have been received for the maiden reverse circulation (RC) programme completed earlier this year at the Medcalf Prospect of the Lake Johnston Project, WA
  • Further high-grade lithium results returned from spodumene-bearing pegmatites, with new significant intersections including:
    • 4m @ 1.21% Li2O from 208m (23CRC017)
    • 3m @ 1.33% Li2O from 110m (23CRC018)
    • 3m @ 1.35% Li2O from 136m (23CRC018)
    • 3m @ 1.44% Li2O from 168m (23CRC018)
    • 3m @ 1.24% Li2O from 101m (23CRC022) 1
  • The drilling at Medcalf has delineated a swarm of stacked spodumene-bearing pegmatites up to 13m thick (down-hole) within a 100m wide corridor along 700m of strike and 250m down-dip 2
  • The results from the maiden drill programme will be modelled to define priority targets for follow-up drilling to test for extensions to the high-grade lithium mineralisation
  • An Aboriginal Heritage survey will commence this week at the Medcalf Prospect to prepare for the upcoming extensional drill programme
Charger’s Managing Director, Aidan Platel, commented:

“The maiden drill programme at Medcalf was a great success, with significant high-grade lithium within logged spodumene-bearing pegmatites intersected on nearly every drill section. The potential for further high-grade lithium mineralisation at Medcalf remains open, and our team is now busy modelling the drilling results in order to define extensional targets for the next phase of drilling.

We will commence an Aboriginal Heritage survey later this week over the area immediately surrounding the Medcalf Prospect in order to be ready for the next phase of drilling. In parallel to this our technical team is busy defining exploration programmes for several other prospective target areas of the Lake Johnston Project, including the exciting Mt Day Prospect, and we’re looking forward to drill-testing these high priority prospects.”

Assays have now been received for all forty-one drill-holes of the maiden RC drill programme completed earlier this year at the Medcalf Prospect. Importantly, high-grade lithium was intersected on nearly every drill section (see Figure 1), correlating well with the logged intervals of spodumene-bearing pegmatites. Significant intersections from the drill programme include: 3

  • 4m @ 1.21% Li2O from 208m (23CRC017)
  • 3m @ 1.44% Li2O from 168m (23CRC018)
  • 4m @ 2.06% Li2O from 145m (23CRC013)
  • 6m @ 1.56% Li2O from 19m (23CRC006)
  • 5m @ 1.41% Li2O from 83m (23CRC007)
  • 6m @ 1.34% Li2O from 24m (23CRC003)
  • 6m @ 1.06% Li2O from 47m (23CRC002)
  • 5m @ 2.55% Li2O from 68m (22CRC002)
  • 6m @ 1.52% Li2O from 26m (22CRC005)
  • 5m @ 1.86% Li2O from 24m (22CRC007) and
  • 4m @ 1.83% Li2O from 56m (22CRC007). 4

The lithium mineralisation at the Medcalf Prospect is hosted within a swarm of anastomosing to tabular stacked pegmatites hosted within sheared amphibolite. The pegmatites are members of the lithium-caesium-tantalum (LCT) pegmatite family (albite-spodumene type) and spodumene has been logged in both the drill chips and in many outcrops. Spodumene is the preferred mineral for the commercial production of lithium, which is one component of modern lithium batteries.

The spodumene-bearing pegmatites are up to 13m in width (allowing up to 2m of contiguous internal waste) and have been delineated on a northwest – southeast strike over 700m long. The pegmatites dip at approximately 40° towards the southwest and currently remain open at depth (Figures 1 and 2).

Upon receipt of the final assays the Company has initiated modelling of the spodumene-bearing pegmatites and the high-grade lithium mineralisation in order to plan follow-up drilling to target extensions of the mineralisation. As part of the preparations for the next phase of drilling, an Aboriginal Heritage survey will commence this week over the area immediately surrounding the Medcalf Prospect. Company geologists will accompany Traditional Owners of the Ngadju people to conduct the survey, which is expected to take several days.

Livium and Mineral Resources Form Joint Venture to Advance LieNA Technology

Livium (ASX:LIT) and Mineral Resources (ASX:MIN,OTC Pink:MALRF) said on Monday (August 11) that they have agreed to a 50/50 joint venture regarding the LieNA lithium-processing technology.

LieNA, the joint venture entity, was formerly a subsidiary of Livium, the owner of the intellectual property for the LieNA technology — an innovative process designed to recover lithium from spodumene.

The joint venture's formation comes after the completion of Stage 1A activities under a joint development deal. The companies first began working together in August 2023, and agreed to additional Stage 1A work in January.

Lithium Prices Surge After CATL Halts Major Mine in China

Lithium prices and mining stocks around the world soared this week after Chinese battery giant Contemporary Amperex Technology (CATL) (SZSE:300750,HKEX:3750) suspended operations at one of the world’s largest lithium mines.

The halt at the Jianxiawo lepidolite mine in Jiangxi province’s Yichun city, a hub for China’s lithium production, came after the mine’s permit expired on August 9.

New Study Highlights Western Australia's Lithium Leadership and Future Potential

Western Australia has a strong lithium history, and a recent study could help inform future exploration.

Put together by researchers from the Geological Survey of Western Australia (GSWA), Curtin University and the University of Western Australia, the report focuses on the formation of high-grade lithium deposits.

It states that Western Australia supplies around 35 percent of the world's lithium, with much of that coming from pegmatite, a coarse-grained rock commonly found in the state's Archean terrains.

AI Uncovers Five Potential Lithium Alternatives for Next-generation Batteries

Generative artificial intelligence (AI) has helped a group of scientists identify five new materials that could power the next wave of batteries without relying on lithium.

The study, published on June 26 in Cell Reports Physical Science, focuses on materials that could enable multivalent-ion batteries — a technology long touted for its potential, but hindered by practical challenges.

Top 9 Global Lithium Stocks of 2025

Lithium prices continued their downward trajectory in 2025's second quarter, with battery-grade lithium carbonate hitting a four year low of US$8,329 per metric ton in late June.

Lithium hydroxide followed suit as oversupply and bearish sentiment weighed on the market.

Despite strong electric vehicle (EV) demand, mine supply — driven largely by China, Australia, Argentina and emerging African producers — has outpaced consumption, with Fastmarkets forecasting a 260,000 metric ton surplus for 2025.

5 Best-performing ASX Lithium Stocks of 2025

Global demand for lithium presents a significant opportunity for Australia.

Australia remains the world’s largest lithium miner, supplying nearly 30 percent of global production in 2024, though its dominance is waning as other lithium-producing countries like Zimbabwe, Argentina and Brazil scale up output.

This influx of supply has pushed lithium prices to multiyear lows, with battery-grade spodumene trading under US$800/tonne — pressuring even efficient Australian producers to trim output or delay projects.
