Abstract
The Mavres Petres mine, operated by Hellas Gold, and the Piavitsa prospect are both located along the Stratoni fault in the Kassandra mining district, northern Greece. These Tertiary deposits are brecciated, carbonate replacement Pb-Zn-Ag-(Au) mineralisations and the Piavitsa deposit is also associated with Au-rich epithermal veins. Both mineralisations were variably overprinted by later fluids as well as ductile and brittle deformation affecting ore mineralogy and trace element distribution. Galena is the main Ag-carrier, contains significant concentrations of Sb and Bi and is locally associated with a suite of Sb-As-Bi phases. Sphalerite is either massive or occurs as a later cockade-textured type. Both varieties are variably enriched in Mn and can exhibit elevated concentrations of In and Ga. In Piavitsa, alabandite is present as small euhedral crystals or in veins in fractured sphalerite. Pyrite is ubiquitous and is either present as disseminations, massive to skeletal aggregates or as a matrix in breccias. It is often arsenic-bearing and even more so towards the later stages. Arsenopyrite appears to be a late phase and occurs interstitial to pyrite and as euhedral crystals. While both arsenopyrite and arsenian pyrite can be enriched in Au, As-minerals are not necessarily associated with Au.
