New World Resources (NWR) has failed to find a buyer for the Dul Paskov mine in northern Moravia and is considering closing the mine if no buyer is found. On the other hand, there are several potential buyers who are interested in OKK Koksovny coking plant, NWR spokesman Vladislav Sobol said. The sale of both plants is part of extensive austerity measures and system changes that NWR announced in May due to its bad economic situation.
