    Seafloor massive sulfide deposits - Wikipedia

    Seafloor massive sulfide deposits or SMS deposits, are modern equivalents of ancient volcanogenic massive sulfide ore deposits or VMS deposits. The term has been coined by mineral explorers to differentiate the modern deposit from the ancient. SMS deposits were first recognized during the exploration of the deep oceans and the mid ocean ridge spreading centers in the early 1960s.

    But the gold found encased in these sulfides is often present in its purest form. With our Tuscarora Nevada based mine we are dealing with sulfide rich tailings that have been exposed to an additional water and air chemical reaction during the early mining processes of the 19th and 20th centuries, this chemical reaction has created a sulfuric acid base – basically a pool of dried battery acid.
