Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copper-zinc which are associated with and produced by volcanic -associated hydrothermal events in submarine environments. [2] [3] [4] These deposits are also sometimes called volcanic-hosted massive sulfide (VHMS) deposits.

Abstract The 14.4-Mt Lalor copper-zinc-gold deposit situated in the Flin Flon Greenstone Belt of north-central Manitoba is large but deeply buried and was discovered using deep penetrating ground fixed-loop time-domain electromagnetic (EM). Results from three different airborne EM surveys over a five-year span permit comparisons of the system

Structure. Ore veins occur as large branching networks of a filler rock, paired with high concentrations of an associated ore type. Copper veins generate above Y=0 and contain copper ore and raw copper, with granite as the filler material. Iron veins generate below Y=0 and contain iron ore and raw iron, with tuff as the filler material.
