Taronga Tin Project Advances Towards Development Approval Following Lodgement of Response to Submissions Report

First Tin PLC, a tin development company focused on advancing low-capex projects in Australia and Germany, is pleased to announce that its wholly owned subsidiary, Taronga Mines Pty Ltd ("TMPL"), has formally lodged its Response to Submissions ("RTS") report for the Taronga Tin Project in New South Wales, Australia.

The RTS provides thorough clarifications to Submissions received from key NSW Government departments and agencies following the public exhibition phase of the Environmental Impact Statement ("EIS"). It also incorporates feedback relating to biodiversity, air quality, groundwater management, and cultural heritage to further optimise the Taronga project design. The lodgement of the RTS report represents a further key milestone in the permitting process and moves the Company closer towards securing Development Approval for its flagship Taronga Tin Project.

Importantly, as previously announced, only four objections were received during the public exhibition period for the EIS. Consequently, the project continues through the standard NSW Government departmental assessment pathway and will not be referred to the Independent Planning Commission ("IPC"), materially reducing anticipated approval timelines, execution risk and permitting costs. 

Key Highlights

· Major permitting milestone achieved with formal lodgement of the Taronga Tin Project's RTS report to the Department of Planning, Housing and Infrastructure ("DPHI"), the regulatory authority.

· Streamlined approval pathway maintained following the receipt of only four objections during the EIS public exhibition period, removing the requirement for an IPC review.

· The RTS provides detailed clarifications to submissions from key NSW Government departments and agencies, including the Environment Protection Authority ("EPA"), Department of Climate Change, Energy, the Environment and Water ("DCCEEW"), Heritage NSW and the Department of Primary Industries and Regional Development ("DPIRD"), and incorporates submission feedback to optimise the Taronga project design.

Next Steps

The remaining approvals process is expected to involve:

1. Final NSW Government departments and agency consultation on the RTS, coordinated by DPHI;

2. Completion of the departmental assessment and preparation of draft approval conditions, to then be reviewed by TMPL ahead of formal Development Approval determination.

First Tin CEO, Bill Scotting, commented:

"The lodgement of the RTS report represents another major milestone for the Taronga Tin Project and further de-risks the pathway to development.

"The very low number of objections received during the EIS process highlights the strong foundations of the project and the extensive engagement undertaken by our team and consultants.

"We now look forward to progressing through the final stages of the approvals process and securing formal Development Approval in due course."

Notes to Editors

First Tin PLC is an ethical, reliable, and sustainable tin production company led by a team of renowned tin specialists. The Company is focused on becoming a tin supplier in conflict-free, low political risk jurisdictions through the rapid development of high value, low capex tin assets in Germany and Australia, which have been de-risked significantly, with extensive work undertaken to date.

Tin is a critical metal, vital in any plan to decarbonise and electrify the world, yet Europe and North America have very little supply. Rising demand, together with shortages, is expected to lead tin to experience sustained deficit markets for the foreseeable future.

First Tin's goal is to use best-in-class environmental standards to bring two tin mines into production in three years, providing provenance of supply to support the current global clean energy and technological revolution.
