Development
Green Technology Metals is primarily focused on advancing the Seymour project, with a goal of starting production in 2026. The company is in the process of securing the final permits needed before beginning construction and is engaged in Indigenous consultation. The Project Development teams are completing a standalone optimized Preliminary Economic Assessment (PEA) and a Definitive Feasibility Study (DFS), while also concentrating on financing and making a final investment decision for the project.
Multiple workstreams underway include:
- Mineral Resource Estimate update incorporating the latest infill drilling from the Seymour project
- Mine geotechnical data interpretation and definition of rock strength parameters for pit design
- Metallurgical testwork focussed on orebody variability DMS testwork and ore sorting amenability
- Mining cost development
- Power supply identification and trade-off studies
- Site geotechnical programs supporting infrastructure and processing plant design
- Optimisation of site infrastructure, earthworks and water management design
- Project implementation planning
- Indigenous Consultation and Permitting
The company has successfully reached numerous critical milestones whilst they continue to advance the Seymour project towards construction readiness
Exploration
Thick, High-grade infill drill results returned up to 2.92% Li20 confirms strong continuity of lithium mineralisation at North Aubry
