Notes To Editors

Critical Mineral Resources (CMR) PLC is an exploration and development company focused on developing assets that produce critical minerals for the global economy, including those essential for electrification and the clean energy revolution. Many of these commodities are widely recognised as being at the start of a supply and demand super cycle.

CMR's flagship asset is the Agadir Melloul copper-silver project in the Western Anti-Atlas of Morocco. It lies approximately 250km south-west of Marrakech and 240km from the deep-water port and industrial zone of Agadir. In August 2025, CMR signed a definitive joint venture agreement with Coppernicus Mining Company SARL AU to earn a 60% interest in six permits covering approximately 65km². CMR currently holds a 50% contractual interest in three of these permits and 20% in the remaining three. A mining licence and an environmental permit for extraction were awarded in Q1 2026. A maiden JORC Mineral Resource Estimate is expected in Q4 2026. It will cover only around 5–6% of the current permit area, and CMR also holds exclusivity over additional ground for future acquisitions.

CMR is building a diversified portfolio of high-quality metals exploration and development projects in Morocco, focusing on copper, silver and potentially other critical minerals and metals. CMR identified Morocco as an ideal mining-friendly jurisdiction that meets its acquisition and operational criteria. The country is perfectly located to supply raw materials to Europe and possesses excellent prospective geology, good infrastructure and attractive permitting, tax and royalty conditions. In 2023, the Company acquired an 80% stake in leading Moroccan exploration and geological services company Atlantic Research Minerals SARL.

The Company is listed on the London Stock Exchange (LON:CMRS). More information regarding the Company can be found at www.cmrplc.com
