Appointment of Exploration Manager

First Development Resources plc (AIM: FDR), the UK-based, Australia-focused exploration company with mineral interests in the Northern Territory and Western Australia, is pleased to announce the appointment of highly experienced geologist Dr David Rawlings as Exploration Manager.

Dr Rawlings brings more than 30 years of geological and exploration experience across government, major mining companies, junior explorers and consulting roles and possesses significant experience across Australia, particularly in the Northern Territory.

His appointment further strengthens the Company's technical capabilities as preparations continue for the fully funded maiden Phase I Reverse Circulation ("RC") drilling programme at the Lander West gold target, with drilling activities expected to commence during July 2026. Dr Rawlings has already commenced work with the Company and is assisting with final preparations ahead of mobilisation.

Tristan Pottas, Chief Executive Officer of FDR, commented:

"I am delighted to welcome David to FDR. Over more than three decades he has built an exceptional breadth and depth of geological knowledge across Australia and, in particular, the Northern Territory, where he has spent much of his career and developed a deep understanding of the region and its prospectivity.

David has been involved in numerous exploration successes and project developments throughout his career and brings a wealth of technical expertise and practical insight to the Company. We are very fortunate to have secured someone of his calibre and I have no doubt he will make a significant contribution as we continue to advance the business.

He has already hit the ground running and is working closely with the team and our operational partners as preparations continue ahead of maiden drilling at Lander West in July. His knowledge of the Territory and hands-on approach make him ideally suited to oversee this important stage in the evolution of the project, and I very much look forward to working with him as we continue to build First Development Resources."
