Coarse Spodumene Concentrate Produced At Seymour With Lithium Recovery Exceeding 72%

Green Technology Metals Limited (ASX: GT1) (GT1 or the Company), a Canadian-focused multi-asset lithium business, is pleased to announce very high spodumene concentrate recoveries from its 100%-owned Seymour Project, located approximately 250km north of Thunder Bay in Ontario, Canada. The spodumene concentrate represents a critical milestone for the business and future off-take partners.

HIGHLIGHTS

  • Flagship Seymour concentrate recovery exceeds 72% using heavy liquid separation
  • Confirms simple 2 stage DMS flowsheet potential
  • Critical milestone for the PEA and future off-take partners
  • Test work based on 1000kg of representative composites as per preliminary mine plan
  • Very high recovery due to large spodumene crystal size
  • Concentrates now being sent for conversion work to Lithium Hydroxide

“The next few months will be an exciting time for the team at GT1 as we focus on increasing the value of our Flagship Seymour Project through metallurgical test work. These results will culminate part of our Preliminary Economic Assessment (PEA) and marks another important step closer to building a vertically integrated lithium business in Ontario, Canada.” - GT1 Chief Executive Officer, Luke Cox

Four composite samples totalling approximately 1000kg of recent and historic diamond core, derived from the Seymour pegmatite was selected, and shipped for testing. The samples represent the different mineralisation phases seen in the pegmatite within, what GT1 expect to be, the final open pit mine shell at Seymour.

Heavy liquid separation (HLS) test work was undertaken at SGS Canada’s facilities in Lakefield, Ontario. SGS compiled a master composite, based on the four samples selected, to provide a preliminary indication of the lithium beneficiation performance by utilising dense media separation (DMS).

Table 1 presents a summary table of the 8 mm HLS test results to achieve an HLS concentrate grade of 6.0% Li2O and 1.2 % Fe2O3. The resulting global HLS recovery, post magnetic separation including losses to HLS fines bypass, is 72%. This recovery has been reduced to align the laboratory magnetic separator with the industrial-scale equipment. The HLS result shows a strong potential to use DMS as the primary recovery method. Further work will continue to be completed for an optimised flowsheet that will ensure both maximised lithium unit recovery, and mass yield will be achieved for the Seymour deposit.

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.
