Deposit characteristics (according to Weber, 1997 “Handbuch der Lagerstätten“)

  • Deposit type: Polymetallic, stratiform complex massive sulphide deposits (volcanogenic-sedimentary)
  • Ore-bearing structures: Elongated ore bodies and lenses
  • Host rock: Early palaeozoic sedimentary to volcanogenic-sedimentary sequences of quartz phyllite, chlorite schist, and black shale
  • Length & thickness: The individual deposits can be traced for several hundred meters and are up to 3.5 m thick
  • Mineralogy:
    • Primary: Pyrite, pyrrhotite, and chalcopyrite
    • Associated: Galena, Fe-rich sphalerite, arsenopyrite
  • Copper reserves of the Panzendorf and Tessenberg deposits (as of 1975; metal content in t):
    • Austrian resource standard: A + B + C Vorräte: (0,8 %) 3000t Cu
    • Potential reserves: (0,7 %) 14000t Cu
  • Estimation of additional Lead & Zinc reserves:
    • In Panzendorf: 0,4 Mt Pb + Zn
    • In Villgraten: 0,1 Mt Pb + Zn
  • Special feature: High-temperature chalcopyrite in granular (mobilized and recrystallized) form, often associated with pure gold & electrum (but never assayed or mined for Au/Ag)

Current work program

  • Systematic field sampling and mapping of all historic targets.
  • D spatial modeling of all historic data and records.
