  • The Wellington Gold-Lead-Silver Mine was closed at the time of data entry with no known plans to re-open. Past operations took place from 1887 to 1966. Production size when active was considered to be small. The ore mined is composed of sphalerite, limonite and anglesite with waste material consisting primarily of fluorite, alabandite and topaz.

  • Sulfide (British English sulphide) is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to chemical compounds large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide.
