Site overview
Pezinok — Kolársky vrch is a former antimony-pyrite mining locality in the Malé Karpaty mountains above Pezinok, Bratislavský kraj. The deposit is identified as one of Slovakia’s largest hydrothermal antimony deposits, hosted in phyllites and black slates of the Pezinok–Pernek crystalline belt. Mining around Pezinok is documented from the medieval period, first for gold and later for pyrite and antimonite.
Small-scale antimony mining at Kolársky vrch began in 1790 and, after interruptions and modern state-enterprise working, ended in 1991 for economic reasons. The record should be treated as the Kolársky vrch deposit area unless a specific adit or shaft can be identified from field evidence.

History
The mining district around Pezinok in the Malé Karpaty has a long and varied history. Several forms of ore mineralisation occur around Pezinok, and mining is documented from the beginning of the fourteenth century, when gold was worked in the area. From the end of the eighteenth century, pyrite and antimonite became increasingly important. Pyrite from the Pezinok and Pernek districts supplied early chemical production, while antimony became the defining mineral of the Kolársky vrch deposit.
Kolársky vrch is one of the principal deposits of the Pezinok district. It forms part of the Pezinok–Pernek mineralised belt and is recognised as one of Slovakia’s largest hydrothermal antimony deposits. The vein system is hosted in older metamorphic rocks, and the deposit is known for stibnite and secondary antimony minerals, including kermesite. It has also been the subject of environmental research because antimony and arsenic occur in mine drainage and ochre deposits from the abandoned workings.
Small-scale mining of antimony ore at Kolársky vrch began in 1790. Mining continued with interruptions into the twentieth century and passed through the state mining enterprise system after nationalisation. The Pezinok branch of Rudné bane worked antimony, pyrite and gold-bearing mineralisation in the Kolársky vrch area until extraction became uneconomic. Mining finally stopped in 1991. The site is best recorded as Pezinok — Kolársky vrch, rather than by the generic enterprise name Rudné bane.
