Reference information

Comments Abandoned, past production: 80 Mt at 25 g/t Ag; 80 Mt at 0.5 g/t Au; 2.7 Mt at 0.3% Cu; 3.7 Mt at 1.5% Pb; and 3.5 Mt at 2% Zn. The largest andesitic volcano in the Central Slovakian Neogene Volcanic Field, Banská Štiavnica, has been a focus of mining of precious and base metals for a long time (Jelen and others, 2003). In the greater Banská Štiavnica intrusive complex, several types of mineral deposits have been recognized, including the Banská Štiavnica porphyry Cu-Mo-Au deposit and related occurrences. The porphyry deposit occurs in granodiorite-quartz-diorite porphyry dike clusters and in the rocks surrounding the granodiorite pluton (Jelen and others, 2003). West Carpathians.
