摘要

The silver and copper mines of Rudabanya (Hungary) are known frommedieval times. Iron ore mines operated from the 19th century until 1985,based on limonitic and siderite iron ore, including several open pits andunderground workings. The mines after the suspension of operation still had.identified lead, copper ore resources. Since the abandonment a short lived exploration aimed to assess the goldpotential producing low gold values but promiseful enrichments of base metalsand silver. A joint HGS-USGS research project has ranked Rudabanya ofhaving high potential for carbonate hosted gold ore enrichment in Hungary. Recently started explorations led to reevaluation of the old archive records(more than 2400 drillholes), and have allowed considering alternativemineralization models. Instead of looking the base metals as possible iron-oreby-products, the data were evaluated to find stand-alone base-metalenrichment zones. The lead ores were chosen first as prime target due to theirhigh silver grades. In the pits both folded stratabound and epigenetic vein-typePb-mineralization were recognized in the footwall zone and penetrating faultsof the siderite ore-bodies. The visually barren dolomites were found holdinghigh zinc values, and the limonite ores hold highly anomalous base metal andsilver values. The results of the first drillholes have supported the model drawn from thesurface mapping, and opened the door for substantial follow-up in base metalexplorations.
