MANAGEMENT CHANGES

Resolute Mining ("Resolute" or "the Company") (ASX/LSE: RSG) advises that it has appointed Mr Gavin Harris as Chief Operating Officer ("COO") from 1 July 2025 following the decision by Mr Geoff Montgomery to step down as COO. Geoff will remain with Resolute as a senior technical adviser and will continue to provide his expertise and guidance across the Company's portfolio of operations and projects.

Gavin is a Chartered Mining Engineer (CEng) with over 20 years of experience in surface and underground mining, having previously worked in West Africa, Australia, Middle East and the United Kingdom across gold, nickel and copper operations.

He has worked on both development projects and producing operations, having worked for companies such as Barrick, BHP, and Teranga Gold. His most recent role was at the Tier-1 Sukari Gold Mine in Egypt for AngloGold Ashanti (formerly Centamin Plc) where he spent six years in senior management roles, most recently as the General Manager.

Whilst at the Sukari Gold Mine Gavin was instrumental in delivering the highest gold production for six years in 2024 (481 koz Au) at lower than budgeted costs and with record safety performance. Additionally, he was responsible for developing and executing several projects at Sukari including the transition from contract mining to owner operated mining in the underground mine and increasing efficiencies in the open pit mining operations both of which led to major cost reductions.

Furthermore, Gavin has been involved in the development of the satellite mines in Senegal at Teranga Gold as the Project Manager of Mine Development as well as development of Cliffs Nickel Project in Western Australia. Gavin has also held senior operational roles at the Leinster Nickel Operations, Western Australia and Henty Gold Mine in Tasmania.

Chris Eger, Chief Executive Officer, commented:

"Over the past three years, Geoff has played an important role in improving operational performance across our mines. We thank Geoff for his work as COO and look forward to his continued technical support as a senior advisor.

We are excited to welcome Gavin to the Resolute team. In Gavin, we have the operational expertise and experience to continue to realize the full potential at Syama and Mako as well as bring Doropo into production, a project with which he is already familiar from his time at Centamin. At the world-class Sukari mine Gavin consistently hit production targets and delivered key projects that improved operational efficiency and reduced costs. This combined with his focus on safety performance makes Gavin ideally suited to lead Resolute's operations as we grow and evolve in this exciting new chapter."
