Critical Mineral Resources PLC (CMRS.L) is a United Kingdom-based exploration and development company focused on critical minerals projects in Morocco, including copper, silver, and other metals essential for the global economy, electrification, and clean energy transition; its core assets comprise the flagship sedimentary copper and silver project in Agadir Melloul featuring a joint venture and plans for a 1,000 tonnes per day mine, the high-grade Igli Silver and Copper project in the Anti-Atlas with silver grades up to 912 grams per tonne and copper up to 2.97%, and additional exploration licenses such as Meseta, Ighrem, and Ifri for copper-gold and critical minerals including manganese, lithium, cobalt, zinc, neodymium, and terbium. Founded in 2017 and headquartered at 25 Eccleston Place, London, the company operates exclusively in Morocco's mining-friendly jurisdiction through its 80% subsidiary Atlantic Research Minerals SARL, acquired in 2023 to leverage local geological expertise for project identification and advancement. Recent developments include the August 2024 acquisition of three additional permits in Agadir Melloul via a special purpose vehicle AgaMel Minerals SARL, transitioning the company from exploration to project development; an exclusive July 2024 option for 90% of the basalt-hosted Igli Silver-Copper project; a November 2025 announcement of positive drilling results confirming mineralization; and ongoing efforts to fast-track mine development while expanding its portfolio of critical minerals opportunities.
