Volcanic-hosted massive sulphide (VHMS) deposit. The mineralization occurs within an ultramafic volcanic breccia, or between the breccia and overlying Mg-rich carbonate rocks and volcanic sedimentary rocks. The volcanic rocks that host the deposit are among the most basic host rocks known for VHMS deposits, and the Derni deposit represents the most basic member in the VHMS deposit spectrum world-wide.
