La Compagnie de Traitement des Rejets de Kingamyambo SA (Metalkol SA), a subsidiary of Eurasian Resources Group (ERG), announced that its site was recently awarded the Copper Mark, making it the first tailings processing operator in history to achieve this rating.
This award confirms that Metalkol’s operations meet internationally recognized environmental, social and governance (ESG) standards for responsible copper production. Metalkol, one of the world’s largest single cobalt suppliers, also produces this important mineral under the same standards.
Copper Mark is a leading voluntary third-party assurance framework that verifies responsible production practices across the copper, molybdenum, nickel and zinc industries. It provides external verification of the site’s performance and complies with the United Nations Sustainable Development Goals, ILO Conventions, Global Industry Standards for Tailings Management (GISTM), OECD Minerals Guidance and ICMM Principles.
Metalkol SA, located in the Lualaba Department of the Democratic Republic of the Congo (DRC), is a leading copper and cobalt producer specializing in the processing of historic mine tailings. Its operations support the sustainable recovery of minerals from the Musonoi River Basin and Kingayambo, contributing to progressive environmental restoration and the economic and social development of local communities.
