Molybdenum creates various genetic ores types which usually occur separately. Considering the economic value, the most important are molybdenum deposits of a porphyry type (the Mo and Cu-Mo sub-type) with the skarn, greisen, hydrothermal, vein, weathering and so-called “molybdenum sedimentary rocks” deposits of a much less importance.
The deposit of molybdenum-tungsten ores with copper in Myszków is located at the north-eastern margin of the Upper Silesian Coal Basin (map), in the contact zone of the Małopolska Block with the Upper Silesian Block along the regional Hamburg-Cracow tectonic zone. The deposit is of the Mo-W-Cu porphyry type. Its ore mineralization is of the stockwork type (a system of quartz veins) containing the impregnating-vein metasomatic-hydrothermal sulfide-oxide mineralization related to the Variscan sour igneous and dacitic (about 300±5 million years of age) activities. The Myszków deposit was documented by the Polish Geological Institute in 1993 as a result of an intensive drilling program in the 1975-1992 period. The program made possible the detailed exploration of Myszków deposit in the area of 0.5 km2 and down to the depth of 1,300 m. The exploration allowed to estimate primarily documented resources of anticipated economic ore occurring at the depth down to 1,000 m at about 380 million tonnes, with 0.23 million tonnes of Mo, 0.18 million tonnes of W and 0.55 million tonnes of Cu and a mean content of Mo and W equal 0.049% and 0.041%, respectively. As a result of the verification carried out in 2007, the anticipated economic resources of the Myszków deposit in C2 category are actually estimated at 551 million tonnes of molybdenum-tungsten ore with copper and the anticipated sub-economic resources at 750 million tonnes. The anticipated economic resources of molybdenum are equal about 0.295 million tonnes, tungsten 0.238 million tonnes and copper 0.8 million tonnes and the anticipated sub-economic resources are equal: 0.298 million tonnes of Mo, 0.212 million tonnes of W and 0.771 million tonnes of Cu (Table 1). The ores from the Myszków deposit have not been exploited so far. It should be added that according to the available data there are high chances for a discovery of other deposits of Mo-Cu porphyry ores with tungsten in the zone of the sour Variscan intrusions occurring along the tectonic Cracow-Lubliniec zone separating the Małopolska Block from the Upper Silesian Block.
Except for the porphyry type ores, molybdenum occurs also in copper and silver ores deposits located in the Fore-Sudetic Monocline and in hard coal deposits within the Upper Silesian Coal Basin area. Nevertheless, molybdenum is not being recovered during technological processes. Numerous occurrences of the Mo-Cu(-W) mineralization have been also found in the zones of Late Carboniferous granitoid intrusions in the Sudety Mts, but no concentrations of an economic importance were found so far in this area.

Anticipated economic resources of the deposit were estimated at about 0.295 million tonnes of Mo, 0.238 million tonnes of W and 0.8 million tonnes of Cu, and anticipated subeconomic resources – at 0.298 million tonnes of Mo, 0.212 million tonnes of W and 0.771 million tonnes of Cu. The Myszków ores have not been exploited so far. It should be added that according to the available data there are high chances for discovery of other deposits of Mo-Cu porphyry ores with wolfram in the contact zone of the Małopolska Block and Upper Silesian Block.
Numerous occurrences of Mo-W mineralization have been found in zones of Late Carboniferous granitoid intrusions in the Sudety Mts, but no concentrations of economic importance were found so far in this area. Molibdenium forms different genetic types of deposits which usually occur separately. Most important are porphyry type deposits (Mo-, and Cu-Mo- subtypes) and less important are skarns, greysens, hydrothermal veins, weathered and Mo-bearing sediments.

Molybdenium co-occurs with other metals in the above mentioned ores of the porphyry type as well as in the atratabound copper deposits in the Fore-Sudetic Monocline and coal deposits in the Upper Silesian Coal Basin. However, the applied technological processes are not aimed at separation of this metal.
The Myszków deposit of molybdenium-wolfram ores with copper is situated at north-eastern margin of the Upper Silesian Coal Basin (map), in the contact zone of the Małopolska Block and Upper Silesian Block separated by the Hamburg-Cracow tectonic zone. The deposit is of the Mo-W-Cu porphyry type. Its ore mineralization is of the stockwork type, forming a system of quartz veins with ore minerals sulfide and oxide related to Variscan igneous activities. Intensive drilling program from the years 1975-1992 made it possible detailed exploration of the Myszków deposit in area of 0.5 km2 and down to the depth of 1,300 m. The exploration carried out in 1993 allowed to estimate inferred resources of the Myszków in the Polish C2 resources category. Anticipated economic resources of ores occurring at depths down to 1,000 m were estimated at about 380 million tonnes, with 0.23 million tonnes of Mo, 0.18 million tonnes of W and 0.55 million tonnes of Cu and mean content of Mo and W equal 0.049% and 0.041%, respectively.
In the last years the economic resources of the Myszków deposit were re-evaluated to find that they are markedly larger than previously estimated, exceeding 550 million tonnes of Mo-W-Cu ores. Anticipated economic resources of the deposit were estimated at about 0.295 million tonnes of Mo, 0.238 million tonnes of W and 0.8 million tonnes of Cu, and anticipated subeconomic resources – at 0.298 million tonnes of Mo, 0.212 million tonnes of W and 0.771 million tonnes of Cu. The Myszków ores have not benn exploited so far. It should be added that according to the available data there are high chances for discovery of other deposits of Mo-Cu porphyry ores with wolfram in the contact zone of the Małopolska Block and Upper Silesian Block.
