Update on Selta Project

First Development Resources plc (AIM: FDR), the UK-based, Australia-focused exploration company, is pleased to announce that it has received formal Notice of Authority to Commence Mining Activities at the Lander West gold target, part of its 100%-owned Selta Project in the Northern Territory, Australia.

The notice has been issued by the Northern Territory Government following the Company's successful application for an Environmental (Mining) Licence ("EML") (Exploration Licence No: EL32755), and the lodgement and acceptance of the required security bond.

This approval represents a key regulatory milestone and enables the Company to proceed with the commencement of mining activities, specifically Reverse Circulation ("RC") drilling at the Lander West gold Target in accordance with the approved environmental and operational conditions.

With all necessary approvals now secured, FDR can proceed with drilling at Lander West - a critical step in advancing the Selta Project and unlocking its gold potential. The commencement of drilling will mark the Company's first material move into active exploration on the ground at Selta, with results expected to drive news flow and project momentum.

The Company will provide further updates as pre-mobilisation and operational activities progress.
