During the Trading session on 20 October 2026, Green Technology Metals Ltd (ASX:GT1) shares were priced at $0.014, a gain of 16.67%. The company's most recent announcement covered in this article is dated 10 September 2026 and is titled "Seymour Project Granted Environmental Assessment Completion". It reported that the company had received formal notice from the Ontario Ministry of Natural Resources confirming that the Environmental Assessment process for the permit to remove forest resources at the Seymour Lithium Project is complete.

Company Background

Green Technology Metals Limited describes itself as a North America-focused lithium exploration and development business, with its head office in Subiaco, Western Australia. Its main 100 per cent owned projects are in Ontario, Canada, and comprise hard rock spodumene Assets at Seymour, Root, Junior and Wisa, together with lithium exploration claims on Archean greenstone tenure in the north-west of the province. The company says all sites are accessible by road and close to hydro power infrastructure and rail.

The company reports a global Mineral Resource estimate of 30.4 million tonnes at 1.17 per cent lithium oxide (Li2O). Of this, the Seymour Project accounts for 10.3 million tonnes at 1.07 per cent Li2O across the North Aubry and South Aubry deposits. The Root Project accounts for 20.1 million tonnes at 1.24 per cent Li2O. Seymour also hosts a rubidium resource of 10.3 million tonnes at 0.27 per cent rubidium oxide (Rb2O).

Environmental Assessment Completion

The company said the Ontario Ministry of Natural Resources has issued a Statement of Completion, which allows permits to be issued for the removal of forest resources across the applied area covering Seymour. GT1 first submitted its project description in November 2022 and was notified on 14 September 2023 that the project was classified as Category B under the ministry's guidelines.

Category B is the second lowest category for assessing impact on the environment and surroundings. The company said the classification indicates potential for low to medium environmental impacts or public concern. GT1 linked the category to the Seymour process design, which it said uses no chemicals and relies on gravity-based separation and processing to produce a concentrate. The assessment required public and Indigenous groups potentially affected by the project to review the project description and provide feedback.

Managing Director and CEO Cameron Henry described Seymour as a small to medium sized operation whose processing, which sorts and washes the mined material and uses gravity to separate spodumene, is comparable with quarrying for road base materials.

Mine Closure Plan and Remaining Permits

The company said it is working through environmental reviews and consultation with Indigenous partners on the proposed Seymour mine closure plan. The final amended draft reflects a reduced footprint, water storage containment and a proposed hybrid open pit and underground strategy, and is under review with all groups. GT1 said it is targeting completion and submission to the ministry this calendar year.

Once filed, the closure plan together with the Environmental Assessment will allow several permits to be issued: including a Permit to Remove Timber, an Air and Sewage Environmental Compliance Approval, water infrastructure approvals for holding dams, a permit to take water and ancillary operating permits. The company said all applications are being prepared and will be submitted to the relevant ministries as they are completed.

Sector Backdrop

Benchmark Minerals Intelligence reported in an article dated 11 August 2026 that lithium carbonate (minimum 99.5 per cent, CIF Asia) stood at US$18,160 a tonne on 10 August 2026, down 5.7 per cent from US$19,250 a tonne at the end of July 2026. Over the same period, 6 per cent spodumene concentrate (FOB Australia) fell 3.3 per cent to US$2,000 a tonne from US$2,069 a tonne.

In the same announcement, the company referred to a lithium market downturn followed by what it called a new cycle for the commodity.

Risks Shareholders Should Weigh

The announcement states that completing the Environmental Assessment is one step in a longer permitting pathway. A mine closure plan must still be filed, and the permits listed above depend on that filing. The company noted that consultation with Indigenous groups and other Stakeholders is continuing and that it is assessing any additional concerns raised.

The forward-looking statements notice says there is no assurance that the company's plans for its projects will proceed as expected and that actual results may differ from those described. Lithium developers are also generally exposed to Commodity prices and project funding requirements, and the announcement does not include financing details for Seymour.

What's Next

The company's stated next permitting milestone is a filed mine closure plan, which it references for the first quarter of 2027. In the same announcement it said it is targeting completion and submission of the plan to the ministry this calendar year, as forecast. Consultation with Indigenous partners on the closure plan and its contents is continuing, and the permit applications listed above will be submitted to the relevant ministerial departments as each is completed.
