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

• Deposit type: Vulcanosedimentary-exhalative
  • stratiform pyrite mineralisation with high grade Cu (Tennantite-Tetrahedrite series)
• Ore-bearing structures: Elongated, low-thickness lenticular ore bodies and enrichments
• Mineralogy:
  • Primary: Pyrite, chalcopyrite, magnetite, chlorite
  • Associated: Pyrrhotite, hematite and traces of bornite, galenite, fahlore (i.e., grey copper ore) and arsenopyrite
• Host rock: Metavolcanites (Tuffs and tuffites)
• Copper reserves/resources* (Status of 1975; metal content in t):
  • A + B + C Vorräte (Austrian resource standard): (1,0 %) 1,000 t Cu
  • Potential resources: (1,0 %) 5,000 t Cu
• Special feature: Quartz veins in the green schists sometimes carry epigenetic bornite mineralisation rich in free gold

Priority exploration targets and historical data*

• Karteis:
  • Hosts 3-4 adits, which are still accessible through tunnels
  • Presence of abundant and coarse-grained chalcopyrite
  • Quartz-pyrite bank with 3-4% Cu and about 35% S
  • Average Cu-value of >2 % from pyrite and Cu-enriched samples
  • 8 % Cu in chalcopyrite sample
  • Length of the deposit is about 2 km and was mined to a depth of 60m
  • Presumption of another parallel deposit

• Kreeberg:
  • Represents a straight continuation of the Karteis deposit
  • Individual samples taken from outcrops in 1918 showed a Cu-content of 2.4% to 7.5% in the chemical analysis.
  • Ores were mined continuously from the surface to a depth of 200 m and a thickness of 24 m
  • In addition, the Kreeberg deposit should contain coarse nickel ores

• Tofern (Alt- and Astentofern):
  • Tofern is separated by the Tofernbach into two deposit parts, namely "Alttofern" and "Astentofern". The latter is said to be particularly rich in copper minerals.
  • Soil material from the valley floor yielded 9000 ppm Cu (After a soil survey from the Environmental Protection Department of the Salzburg Provincial Government)
  • Total length of mineralised zone is 7 km
  • Astentofern contains the longest gallery of the Großarl mining area, which is about 1000-1100 m long

* Data collected from historical reports from 1937/38, as well as from a governmental soil survey from 1998

Current work program

• License area expansion by >100% to cover the entire known copper producing district.
• Systematic field sampling and mapping of all historic targets.
• 3D spatial modeling of all historic data and records.
• Drone aeromagnetic survey to investigate extension zones to known deposits.
• Submission of drill permit applications to test historic deposits for compliant Cu-Au-Ag grades.
