A dense layered mix (from top to bottom) of dark red bubbly #goethite, silver crystalline #arsenopyrite, golden yellow #chalcopyrite and lighter red country rock with minor clusters of green #chlorite throughout. Fossicked from #minewaste at Wheal Fortune (Great Consolidated Mines), Gwennap, #Cornwall.

This is a typical mix of Cornish mining minerals. You don't want to drop this one on your toe, it's really heavy for it's size.
