Exploration Update for the Bynoe Lithium Project

Charger Metals NL (ASX: CHR, ‘Charger’ or ‘the Company’) is pleased to provide an update on its exploration activities at the Enterprise Prospect of the Bynoe Lithium Project, Northern Territory.


  • Ambient Noise Tomography (ANT) survey has commenced over the northeast area of the Bynoe tenement which remains relatively underexplored
  • Ground gravity survey has also commenced over a large area in the northeast of the Bynoe tenure
  • The results from the two geophysical surveys will be used to detect any potentially large “blind” pegmatite systems that do not outcrop at surface
  • Infill surface geochemical sampling and mapping is underway over prospective areas to the east and northeast of the tenure
  • Nearly 12,000m of drilling has been completed to-date at Bynoe across 7 prospective target areas. Results will be released in batches when received, and are expected from mid-September
The Company has commenced an ANT geophysical survey in the northeastern portion of the Bynoe tenure (Figure 1). ANT is a form of passive seismic surveying that uses ambient sound waves to detect contrasting rock units, and has been used to successfully detect “blind” pegmatite systems that cannot be seen at surface. This is a particularly useful exploration tool at Bynoe to “see” below the strong weathering profile at surface to potentially detect large pegmatite systems that do not outcrop.

Simultaneously the Company has initiated a ground gravity survey over the northeastern portion of the Bynoe Project (Figure 1). Petrophysical testwork completed on drill core from the Company’s diamond drilling has shown a significant density contrast between the pegmatites and the metasedimentary country rock. As such, ground gravity has the potential to detect significant pegmatite systems at Bynoe, particularly when modelled in conjunction with the ANT survey results.

Concurrent to the geophysical surveys Charger has commenced infill surface geochemical surveys over key prospective areas at Bynoe (Figure 1). Areas of no previous sampling or wide-spaced (400m) sampling are being infilled to 200m line spacing. This is important given that the known lithium-bearing pegmatites in the region typically have a strike length of 300m or less.

All three surveys will be completed in the next four to six weeks, with modelling and target generation completed in October.

Reverse-circulation and diamond drilling has continued at the Bynoe Lithium Project. Sixty-three RC holes for 10,009m and six diamond drill-holes for 1,915.16m have been completed over seven prospect areas (Figure 2). Assay turnaround times have increased due to a number of factors such as sampling processing time and an influx of samples at the laboratory. The Company intends to release the assays results in batches when they are received, with the first significant batch of results expected in mid-September.

Charger’s Managing Director, Aidan Platel, commented:

“The Company has completed a significant amount of drilling to-date at Bynoe across several key prospect areas, and we look forward to receiving the assay results for each of the target areas that have been drill-tested so far.

In addition to systematically drill-testing seven of the numerous (>20) prospects already identified, the Company has initiated simultaneous ANT, gravity and surface sampling surveys in key areas of the Bynoe Project that are currently considered prospective yet underexplored. The surveys have the ability to delineate new high priority drill targets, including targets that are not apparent at surface, and we look forward to seeing the results and modelling of these surveys in October.”

Top 5 Canadian Lithium Stocks of 2025

The lithium market continued to battle headwinds during the first quarter of 2025 as residual oversupply weighed on prices, pushing them to a four year low.

Weaker-than-expected demand to start the year also added pressure to the oversupplied market, resulting in the lithium carbonate CIF North Asia price to fall below US$9,550 per metric ton, its lowest point since 2021.

Analysts have suggested the persistent downturn is the signaling of a market bottom. This theory is further supported by a projected production reduction that will help absorb market oversupply.

Funding the Energy Transition: The Role of Public and Private Finance in Building Supply Chains

The energy transition demands substantial funding as participants look to build out infrastructure and supply chains, but experts say new solutions are emerging to help navigate this landscape.

During the "Financing the Energy Transition" panel at the Benchmark Summit, participants discussed the role of government and public sector investment, as well as the outlook for Canada's electric vehicle (EV) supply chain.

Moderated by Adam Webb, head of battery raw materials at Benchmark Mineral Intelligence, the discussion at the Toronto-based event opened with a snapshot of Canada’s EV battery supply chain buildout.

Top 4 Largest Lithium Reserves by Country

Those interested in the lithium sector and investing in lithium stocks are often curious about which countries are the top producers of the battery metal, but they may not stop to consider the top lithium reserves by country.

Major lithium-producing countries are, of course, home to a large number of lithium companies. Many of the world’s top lithium producers also hold significant reserves, and their reserves can give an idea of how much room those countries have to grow. At the same time, nations with high reserves may become more significant lithium players in the future.

Looking forward, lithium demand is expected to continue increasing. That’s because, together with metals such as cobalt, lithium is a key raw material in the lithium-ion batteries used to power electric vehicles, and it is also essential for the energy storage sector.
