On December 28, 1959 by the decision of the Ministry of Heavy Industry, Zakłady Górnicze Lubin was established as a state owned company and in 1961, transformed into Kombinat Górniczo-Hutniczy Miedzi (KGHM), which was supposed to deal with the extraction and processing of copper extracted from the newly discovered fields. At the same time, KGHM incorporated two copper mines in the area of the piedmont of the Sudetes from the old copper-bearing basin (closed in 1973 - Lena and in 1987 - Konrad).
