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.
