    VMS. Deposits. Volcanogenic Massive Sulphide ("VMS") deposits are base metalrich mineral deposits, which can also contain lesser amounts of precious metals. Their ores can be major sources of zinc, copper, and lead, with gold and silver byproducts. VMS deposits are found worldwide, and often form in clusters, or camps.
