The Deep Głogów copper ore deposit is located in the Lower Silesia region of Poland. The project is wholly owned by KGHM. The mineral resources are estimated at over 300 million tonnes with average copper content of 2.5%. They constitute one-fourth of KGHM's copper resources and around one-third of its silver resources in all of the areas concessioned by the company in Poland. Infrastructure from the Rudna and Polkowice-Sieroszowice mines is used to access the deposit.
„Głogów Głęboki-Przemysłowy” deposit is characterized by the biggest depth of orebody occurrence from all deposits operated by KGHM. The orebody layers are located deeper than neighboring Rudna and Sieroszowice deposits, the maximum deepness of deposit reach around 1385 m in depth. Geological works, that were done so far in deposit area, shows less frequent orebody faulting, but with depth increase much more common and intensive thermal and gas events than in other deposits. In “Głogów Głęboki-Przemysłowy” balance mineralization is presented in all three main lithological types of ore: sandstone amount to 60% of resources, shale – 13% and dolomites – around 27% of industrial resources of this deposit.
The first preparatory and exploration work in the Deep Głogów area started in June 2005.
The project encompassed construction of the GG-1 ventilation shaft, the expansion of the central air conditioning system, and construction and outfitting with basic technical infrastructure.
Construction of the new shaft has been divided into stages with completion planned in 2020. This shaft will be the deepest of KGHM’s 31 shafts in the Copper Belt with a targeted depth of 1340 m and diameter of 7.5 m. Preparations for the opening of a mining section in mine field 28/1 took two years. In April 2014, the first bucket of ore was extracted at the depth of 1200m from the Deep Głogów area. Work currently underway involves the sinking shaft, construction of the surface - based ventilation station at the R-11 shaft and of drifts to access subsequent areas of the deposit.
According to estimates, in the years 2028-2035 – the peak period of mining of the Deep Głogów deposit – output from this area will be 10-11 million tonnes of ore and 200-220 thousand tonnes of electrolytic copper annually.
