Data Metallogenica is the global encyclopaedia of ore deposits. It is the world’s largest mineral deposit database, a unique technical information system made possible through the support of over one hundred international Foundation Sponsors from industry, government and professional societies. DM is a self-funding but not-for-profit enterprise, owned and operated by AMIRA International on behalf of the global minerals industry and associated institutions. Data Metallogenica will continue to develop as a major reference, training and educational resource for all, as well as being a key repository of much transient and valuable information on ore deposits.
