      NATIVE SILVER CRYSTAL

      COBAR-NSW AUSTRALIA

      RARE SILVER SPECIMEN

      artistic and aesthetic silver specimens

      A fine miniature specimen consisting a of a thin sliver

      outstanding specimen of silver crystal wire,

      Native Silver Crystal Cobar.  A specimen of natural crystalised Silver from Cobar, NSW, Australia. Hard to come by.  Good branching and looks outstanding under magnification. 

      A silver-lead-zinc-copper deposit discovered in 1974 was originally worked as the Elura mine but presently (2005) is worked as the Endeavor mine.
      Located in Booroondarra Parish near Cobar.

      Coordinates: 371700mE, 6551350mN.
      A lenticular massive sulphide deposit.

      The Endeavor zinc-lead-silver mine is located 43km NNW of Cobar. The mine contains two styles of mineralisation: above about 900m depth an irregular sub-vertical sheet is hosted by a turbidite sequence and broadly coincides with an anticline axial plane; at the bottom of this sheet mineralisation bifurcates into grossly concordant zones. These concordant zones are hosted by a shale-rich sequence and underlying limestone.

      The Electrolytic Zinc Company of Australasia Ltd discovered the orebody in 1973. Initially a bullseye anomaly was identified in an aeromagnetic survey, with diamond drilling intersecting ore in 1974 (Schmidt 1989). Mine production from what was initially known as the Elura orebody began in 1983. In 1998 drilling beneath the mine at over 1000m below the surface intersected mineralisation close to the contact with limestone, which until that time, was not recognised as occurring in the mine area.
