Frenštát is located in the northeast of the Czech Republic. The two shafts at Frenštát were built in the 1980s but were never brought into operation. Under the Czech Mining Act, NWR is obliged to maintain and look after the mine in order to prevent degradation, in particular of the technical conditions, water conditions and safety.
Frenštát is currently in exploration phase. The deposit is estimated to hold approximately 1.6 billion tonnes of hard coal resources.
