Deposit DEPOSIT LIES IN AN FE ORE HORIZON AND HAS BEEN A MAJOR CU PRODUCER IN EUROPE FOR CENTURIES. THE OREBODIES ARE RICHER IN CU TOWARDS THE MARGINS. EAST AND WEST OF THE CENTRAL BODY ARE ZONES OF DISSEMINATED ORE WITH CHALCOPYRITE, PYRITE, PYRRHOTITE, SPHALERITE, MAGNETITE, AND GAHNITE. IN THESE AREAS NATIVE AU IS FOUND WITH WEIBULLITE (PB-BI-SE MINERAL).
Deposit Discovery Year: 11TH CENTURY
