Development

Seymour Project: Advancing Towards Production

Green Technology Metals is focused on developing the Seymour Lithium Project, targeting first production in 2026. The company is actively securing the final permits required for construction while maintaining a strong commitment to Indigenous consultation and stakeholder engagement.

Our Project Development team has recently completed an optimized standalone Preliminary Economic Assessment (PEA) and is now progressing towards the completion of the Definitive Feasibility Study (DFS). Concurrently, efforts are underway to secure project financing and reach a Final Investment Decision (FID).

The company has successfully reached numerous critical milestones whilst they continue to advance the Seymour project towards construction readiness
