The Region of the so-called Old Belt despite limited production becomes one of the regions where considerable part of the mining staff gain experience and take part in construction of Polska Miedź. Here also, fully successful, reactivation of mines created favourable conditions to undertake geological search of copper ore deposits, on the full scale in the region of Lubin and Głogów, which was at those times a blank spot on geological maps. Apart from mining works, exploratory drillings were conducted around Złotoryja. The results of this research allowed expansion of such mine as 'Lena' and construction of the new 'Nowy Kościół' in the town of the same name. Mining was performed first in April 1955, and extracted ore was processed in the Enrichment Plant of Konrad mining site in Iwiny.

On 1953, first mechanical metallurgical plant buildings were operational and their construction started in 1951 -these were the beginnings of the steel industry in Lower Silesia. On 24 December 1953, the first casting of copper from the furnace reverberator was performed, which was the beginning of smelter operations. In 1954, more than 5 000 Mg of cathode copper were produced. In subsequent years, the program of the plant construction was implemented which in January 1959 influenced technological launch of particular facilities, and in July that year the smelter was commissioned.

Initially, drilling program prepared by Jan Wyżykowski gained many negative opinions. The main argument which was not in favour of works was the claim that German geologists' works did not confirm deposits around the area. Government Resolution helped Jan Wyżykowski in his goal, the Resolution appointed Polish Geological Institute to discover deposits of copper to support national economy. As a result, drillings were continued and their consequence was discovery of the first Lubin-Sieroszowice deposit on 23 March 1957.

The basic problem for builders of the Copper Belt was related to the sinking of shafts. Up to 1960 shaft works under such difficult conditions of strongly hydrated rock mass were not conducted in Poland. Availability of copper ores deposit required freezing of the rock mass, which at those times was extremely difficult. Construction of shafts, from the perspective of LGOM mining undertakings includes a number of developmental stages. The first falls on the years 1960-70 and includes construction of 'Lubin' and 'Polkowice' mining shafts. Experiences gained during sinking of these two shafts allowed construction of monitoring apparatus for the freezing process and unfreezing of the freezing mantle which was beneficial during construction of other shafts.

Management of Legnica-Głogów Copper Belt involves establishment in 1960 in Lubin state-owned company under the name the Zakłady Górnicze 'Lubin w budowie'('Lubin under construction' Mining Plants). These plants were transformed on 1 May 1961 into Kombinat Górniczo-Hutniczy Miedzi in Lubin, whose task was to construct mines, ore enrichment plants, copper smelter and construction of auxiliary and social facilities.

Construction project of 'Rudna' mine initially, assumed target mining capacity at the level of 7.5 million Mg of ore annually. In order to construct 'Rudna' ZG mine knowledge and experience gained during construction of previous shafts were used, which resulted in the shortest period of production capacity. 'Rudna' is the largest LGOM mine with preferably the best designed mining structure which is suitable for deposit conditions and adequately technically equipped, which enables to obtain the highest mining capacity. In July 1974 'Rudna' Mining Plants obtained 25% of designed mining capacity, which was the basis for transformation of these Mining Plants into mining units. In the same year technical-economic expansion assumptions were prepared with target mining capacity at the level of 12 million Mg of ore annually.

Copper industry definitely and favourably performed the restructuring process and adapted to the conditions of the market economy. In place of the previous Kombinat Górniczo-Hutniczy-Polska Miedź in September 1991 one-person Company of State Treasury - KGHM Polska Miedź S.A and the Company's authorities - Management Board and Supervisory Board were established. It implies privatisation, as well as preparation for independent sales transactions. Launching an office in London.

To launch Precious Metals Plant and processing of anodic sludges according to Swedish technology was one of the most important technological achievements of 'Głogów' HM. The decision on construction of the Plant was made in 1990 and in 1993 technological start-up was conducted. Full operation began in February 1994. The Plant produces refined silver, gold, platinum-palladium sludge and selenium.

'Polkowice-Sieroszowice' Mining Plant is a branch which includes two former mines: 'Polkowice' and 'Sieroszowice'. Up to 1995 these mines formed separated branches of KGHM Polska Miedź S.A On 1 January 1996 under restructuring activities their merger took place. These transformations improved management, rationalization of resources management, use of the production capacity of Ore Enrichment Plants as well as allowed the effective implementation of thin deposit mining and reasonably conduct the investment works.

In June 1997 public offer of KGHM Polska Miedź S.A shares was conducted, under which the State Treasury sold 32. 8% (65 732 200) of the Company's shares.

Individual investors purchased shares at the price of PLN 19 and under the tranche for institutional investors shares were sold for PLN 21.

30 000 000 shares (15%) were free of charge for the Company's employees with 2 year-long sales freeze.

Regarding complex geological and mining conditions as well as the scope and diversity of works, this is one of the most complicated undertakings.  Costs of this investment was estimated to reach more than 80 mln dollars.

The SW-4 shaft is necessary to start exploitation of deposits of copper ore in the area called Głogów Głęboki Przemysłowy (Deep Industrial Głogów). It was planned as an air conditioning shaft, 1260 m deep, which will allow to use maximum performance of the main fans station in the Polkowice-Sieroszowice mine.

At the end of 2006, within the scope of expanding the assortment of products and meeting the customers’ expectations, a new line for production of wire from oxygen-free copper, 8 mm in diameter, with the Upcast technology, was started up in the Cedynia Copper Smelter. Therefore, the manufacturing performance increased by 15 thousand tons per year. The Upcast process assumes production of high-quality wire characterized with even structure in its cross-section.

Global Depository Receipts (GDR) were listed on the London Stock Exchange (LSE) since July 1997. On 22 Decemebr 2009, upon the company’s request, the GDRs were removed from the list of securities admitted to trading in LSE, and the GDR program in the KGHM Polska Miedź S.A. Was terminated.

The Company under the name KGHM Ajax Mining Incorporated is supposed to implement the mining project of copper ores and gold exploitation from Afton - Ajax deposit in Canada.

This year was rich in jubilee events. During the jubilee session the last fifty years of the company were summed up and discussions about prospects were held. State awards and honorary badges were awarded. On the occasion of the jubilee, KGHM issued a special CD with Polish hits of the last 50 years.

One of the key events in the history of KGHM Polska Miedź S.A. in the area of resource base development the Canadian company Quadra FNX Mining Ltd was friendly acquired. (today KGHM INTERNATIONAL LTD), with its registered office in Vancouver. KGHM purchased 100% of company's shares quoted on the stock exchange in Toronto. This transaction was at that moment the largest foreign investment in the history of Poland

On 19 March 2013 IN Mining Plant in Rudna, in section G-3 of Main Rudna mine, at a depth of 960 meters there was a quakes of a rock mass. A quake as 1,6 x108J.  It was one of the strongest shocks in the Polska  Miedź. There were 19 employees trapped underground, there was no contact with them. For more than seven hours, five teams of Mining and Metallurgical Rescue Unit tried to get into the cut off miners. Rescuers managed to reach miners from the mine Polkowice - Sieroszowice.  No employee suffered serious injuries then.

The Sierra Gorda mine, one of the largest and the most rapidly developing projects in the world, was officially opened. The opening ceremony was attended by many personalities, including the president of Chile: Michelle Bachelet.

At the opening the mine was named after Ignacy Domeyko. He was the Polish geologist who most of his life spent in Chile and contributed to the development of the country from both an industrial and socio-cultural perspective.

The processing of copper ore in the Sierra Gorda processing plant started in July 2014. The first transport with ca. 6,000 tonnes of concentrate left the mine in November of this year.
