Green Technology Metals Limited (ASX:GT1) explores and develops hard-rock lithium projects in northwestern Ontario, including Seymour, Root, Junior and Wisa. Its September 2026 report placed Seymour’s completed environmental assessment within a wider permitting programme that still requires consultation, studies and project financing.

Environmental Assessment Completed

The Ontario Ministry of Natural Resources issued a Statement of Completion on 10 September 2026 for the Seymour Environmental Assessment. ASX:GT1 said this enables forest-resource removal permits to be issued, but does not mean that every approval needed for development has been secured.

The Mine Closure Plan was nearing completion and remained under review with Indigenous partners. Technical completion with Qualified Person certification was targeted for December 2026, followed by filing within calendar 2026. The company linked potential shovel-ready status to filing and the relevant First Nation approvals for timber removal. Consultation had been affected by wildfires and evacuations in July 2026.

Feasibility Study and Investment Timing

ASX:GT1 moved the Seymour Definitive Feasibility Study completion target to the first quarter of 2027 to align with the permitting process. A Final Investment Decision is targeted for mid-2027, but depends on Impact Benefit Agreements and financing. Neither milestone is a completed decision or a guarantee of construction.

The distinction between completing an environmental assessment and securing a construction funding package remains important. The quarterly report did not identify finalised financing for the targeted investment decision.

Resource and Technical Work

The company cited a combined resource of 30.4 million tonnes at 1.17% Li2O across its projects. Seymour accounted for 10.3 million tonnes at 1.07% Li2O and 0.27% Rb2O. These were previously disclosed resource figures repeated in the 2026 quarterly update, not newly reported estimates. ASX:GT1 also described tantalum test work aimed at a saleable concentrate near 25% Ta2O5.

Root saw no substantial work during the quarter, while group exploration expenditure was A$477,000. The company also reported an Ontario Critical Minerals Innovation Fund grant of up to C$500,000 for eligible costs, with C$200,000 received.

Funding Position at September End

Cash was A$7.788 million at 30 September 2026, compared with A$9.245 million three months earlier. ASX:GT1 recorded operating cash outflow of A$965,000 and investing outflow of A$481,000, including A$477,000 for exploration and evaluation. Financing outflow was A$8,000 in lease repayments.

The company estimated available funding at approximately 5.4 quarters and reported no unused facilities. It also stated that additional financing would be required to reach a Final Investment Decision. In August 2026, it joined the US Defense Industrial Base Consortium with a focus on lithium, tantalum and rubidium.

Key Insights

Seymour completed an identified environmental assessment stage in September 2026, but the closure plan, Indigenous consultation, feasibility study and financing remained distinct outstanding steps. For ASX:GT1, the announced schedule centres on planned December 2026 documentation, a first-quarter 2027 feasibility study and a conditional mid-2027 investment decision.
