Reference information

Comments Polish Geological Institute identified mineralization in the area in the 1960s; drilling confirmed the presence of a Mo-Cu-W deposit (Strzelecki Metals Limited, 2010). Myszkow is one of several porphyry copper-type deposits in central Europe that occur within the buried Paleozoic Cracow-Silesian orogenic belt, a zone where continental or island arc volcanic activity probably occurred in the vicinity of convergent plate boundaries (Chaffee and others, 1994). The deposit is located on a major northwest-southeast-trending fault system in the Malopolska Block, a major geological unit of Southern Poland (Strzelecki Metals Limited, 2010). These host rocks are a complex of metasedimentary rocks that have been intruded by a Late Carboniferous predominantly granodioritic pluton. Geochemical characteristics, mineralogy, and vein morphology at Myszkow are typical of calc-alkaline porphyry copper deposits elsewhere (Strzelecki Metals Limited, 2010). Myszkow is enriched in copper and molybdenum but contains little gold ; 0.041% W in ore.
