Attendance at Industry Conferences

Strategic Minerals plc (AIM: SML; USOTC: SMCDF), an international mineral exploration and production company, is pleased to announce that it will attend the following industry events as part of London Mining Week 2025.

Critical Minerals Association (UK) Annual Conference

The Company, along with Dennis Rowland, Managing Director of Strategic Minerals' wholly owned subsidiary, Cornwall Resources Limited ("CRL"), will attend the Critical Minerals Association's (UK) ("CMA UK") fifth Annual Conference in London on 1 December 2025. As part of the conference's events, the Company will co-host, with Cornish Metals plc, a tin-tungsten roundtable meeting with a select group of invitees.

CRL was one of the founding members of the CMA, and Dennis Rowland is currently the co-chair of the CMA's UK Domestic Mining Working Group. Through its membership, the Company has gained support for its activities and submitted evidence against key government initiatives and fact-finding calls for evidence. Through the CMA, Dennis Rowland was also able to contribute towards responses to the UK Critical Minerals List and the newly released Critical Minerals Strategy.

The CMA UK is a key interlocutor between the UK Government and the critical minerals industry, seeking to support the development of socially and environmentally responsible critical mineral supply chains for the UK's security of supply. The CMA UK unites industry, academia, and other stakeholders to address risks in critical mineral supply chains.
