Directorate Change

Appointment of Chris Gibbs as Independent Non-Executive Director

ECR Minerals plc (LON: ECR), the exploration and development company focused on gold in Australia, is pleased to announce that, further to the Company's announcement of 8 September 2025, Chris Gibbs has been appointed to the board of ECR Minerals (the "Board") with effect from 26 November 2025 as an Independent Non-Executive Director.  Chris has been a consultant to ECR since September 2025 and his appointment to the Board forms part of his consultancy arrangements with the Company.

Chris brings over 25 years of international mining executive experience, spanning North America, Australia, Europe, Africa and South America. His career includes executive positions with a number of large international mining companies, including Centerra Gold, Placer Dome, Argonaut Gold and Barrick Gold.

Chris was the former CEO of ASX-listed American Rare Earths, when it advanced its 2.63 billion tonne Halleck Creek rare earth project and substantially grew its market capitalisation. At American Rare Earths, he was instrumental in its transformation into a development-ready US rare earths company, which substantially increased its market value. At Argonaut Gold, he oversaw the Magino Gold Project from feasibility through to construction and operations readiness. Earlier roles with Centerra Gold, Barrick Gold and Placer Dome involved large-scale mine development, operational turnarounds and cost transformation initiatives across multiple jurisdictions.

Chris currently serves as a Non-Executive Director of ASX-listed Godolphin Resources Limited and is a Director of the Critical Minerals Institute.  He resides in Queensland, Australia, the state in which ECR's core Blue Mountain and Lolworth Projects are located.

Chris will continue to take half of his remuneration in ECR ordinary shares, in line with the rest of the Board in being partly remunerated through equity and aligning their interests closely with those of ECR shareholders.

ECR Chairman Nick Tulloch commented: "I am very pleased to welcome Chris Gibbs to our board of directors.  As I said when Chris began working with us in September, his experience in developing multi-million-dollar mining projects is self-evident.  ECR is changing.  Through our proposed acquisition of the Raglan Project and our ongoing project at Blue Mountain, our strategy for the next stage in our development is gold production and we believe that Chris' expertise will guide us in the execution of these opportunities."
