In addition to visual identification, streak tests & hardness tests, MBMG Bulletin 84 (Earll 1972) describes the Cable Mine, only a few miles from the Spain Mine, where ore consists of “coarse calcite with quartz, pyrite, pyrrhotite, arsenopyrite, magnetite, & gold,” provides a direct analog for the arsenopyrite-pyrite-calcite-quartz association.Identified by Bill Hamel: Visual Identification |
