All your ASX lithium news for Wednesday, August 10


Researchers have found a way to trace the origins of lithium to make sure producers are only using ethical sources for the metal.

We all know lithium is in high demand but so too is solid ESG credentials from the end consumers who buy electric vehicles.

Lithium has a less problematic supply chain than cobalt for example, but when vast quantities of water are used to extract lithium from ores it can lower groundwater levels and face the ire of indigenous communities – like when major producer Sociedad Química y Minera de Chile SA’s (NYSE:SQM) application to expand its operations was blocked by a Chilean court in 2019 after Indigenous groups protested that the company was overdrawing brine and affecting water reserves.

“It’s important to know the origin of lithium because, depending on where the lithium comes from, its exploitation can generate environmental or societal problems,” French Geological Survey researcher and study author Anne-Marie Desaulty told New Scientist.

“Water scarcity and human rights violations are major issues.”


Tracing lithium’s atomic signature

Lithium has two stable isotopes, and each source of lithium has unique ratios of these isotopes which act like a signature.

Desaulty and her team looked at studies of isotopic ratios of lithium collected from different mines and found that lithium obtained from brine deposits has a different isotopic signature from the lithium sourced from hard rock.

While the researchers couldn’t link the lithium in the batteries to specific locations without the reference samples, they think this could be done in future.

Car manufacturers like BMW, Tesla, and Volvo have already said they plan to increase the transparency of their supply chains for EV batteries.

And Desaulty says paper trails are easy to fake, so a reference database with comprehensive up-to-date data on available [lithium] products must be developed.

“Traded materials can be analysed to provide additional credibility to document-based traceability systems with due-diligence concepts for raw material supply chains,” the researchers said.

“Implementation of a certification system for lithium will boost the development of a responsible, sustainable and stable supply of raw materials for batteries.”

The company has flagged the largest single interval to date at its Manna project in WA of 24m at 1.03% lithium – including 11m at 1.37% Li2O from 164m and 6m at 1.27% Li2O from 177m.

The RC drilling also returned results which extend the northern strike by 220m from the existing assay results.

The RC drilling program is currently focused to drill out this extended area so that results can be included in the updated Mineral Resource Estimate (MRE), which the company plans to release in Q4 2022.

An additional Program of Works (POW) has been submitted to the Mines Department to cover off the expanded exploration program.

Breaker Resources (ASX:BRB) also welcomed the results, since Manna sits within their 1.7Moz Lake Roe Gold Project, and the company retains a 20% free-carried interest in the project – with Global Lithium carrying all costs and expenditure to completion of a positive bankable feasibility study (BFS).


At the company’s Cancet project in Canada, surface stripping and mapping of the main pegmatite duke has started, with new drill targets for the upcoming autumn/winter campaign expected to be generated soon.

“Exposing sections of the main pegmatite dyke and carrying out channel sampling will help us build a clearer understanding of the highly prospective area,” MD Chris Evans said.

Plus, Winsome has nabbed a heli-portable reverse circulation (RC) and diamond drill rigs for its autumn exploration programs at Cancet and Adina.



Phase II RC drilling program at the Niobe rubidium-lithium project with multiple 50 meter+ pegmatite intervals intersected.

The target of the drilling is a possible extension of the Breakaway pegmatite towards Niobe flats, as well as infill drilling at the Niobe Main pegmatite to assess the high-level resource potential of the contained lithium and rubidium within the Q1 completed drilling envelope at Niobe.
