位于斯洛伐克Banská Štiavnica矿区的Banská Belá、Kopanice、Treiboltz和Rabenstein的中世纪采矿场是低温热液银金矿点。迄今为止，已开采矿石的矿物学基本上是未知的，因为这些矿山最富有的部分已经在三个世纪前耗尽。然而，对旧矿山和最近完成的钻孔样品的研究使我们能够收集新的矿物学数据。在Banská Belá，银矿物包括棘银矿、多碱-珠光体矿、硫银矿、千金藤、稀有的绿硫银矿和自由硫银矿，主要以包裹体形式存在于黄铁矿中。在Kopanice，主要的银矿物是棘铜矿，唯一的贱金属硫化物是黄铁矿。这两种矿物通常都被未命名的AgFe（Ni）或AgSe（Te）硫化物镶边。在Treiboltz，占主导地位的银载体是hessite和benleonardite，都与方铅矿。拉本斯坦的主要银矿物是银银矿和银银矿。银和uytenbogaardtite存在于所有网站除了Treiboltz。此外，贱金属硫化物（黄铁矿、黄铜矿、方铅矿、闪锌矿）可能也很丰富。贱金属硫化物是最古老的矿石矿物组合，其次是后来的热液脉冲沉淀的金银矿物。一些贵金属硫化物可归因于晚期次生富集，这些次生富集很可能使Au和Ag的开采持续了几个世纪。
The Medieval mining sites at Banská Belá, Kopanice, Treiboltz and Rabenstein in the Banská Štiavnica ore district (Slovakia) are epithermal Ag-Au occurrences. The mineralogy of the exploited ores has largely been unknown up to date because the richest parts of those mines were exhausted already three centuries ago. However, studies of samples from old mines and recently completed drillholes allowed us to gather new mineralogical data. In Banská Belá, the Ag minerals include acanthite, polybasite-pearceite, pyrargyrite, stephanite, rare proustite and freibergite and occur mostly as inclusions in pyrite. In Kopanice, the main Ag mineral is acanthite and the only base-metal sulfide is pyrite. Both minerals are often rimmed by unnamed AgFe (Ni) or AgSe (Te) sulfides. At Treiboltz, the dominant Ag carriers are hessite and benleonardite, both associated with galena. In Rabenstein, pyrargyrite and freibergite are the main Ag minerals. Electrum and uytenbogaardtite are present in all sites except Treiboltz. In addition, base-metal sulfides (pyrite, chalcopyrite, galena, sphalerite) may be also abundant. Base-metal sulfides are the oldest ore minerals assemblage, followed by a later hydrothermal pulse which precipitated Au-Ag minerals. Some of the precious-metal sulfides can be assigned to late secondary enrichment that most likely sustained the mining of Au and Ag for centuries.
