The accompanying analysis considers the combined production of four underground mines, Lubin, Polkowice-Sieroszwice, Rudna and Deep Glogow, and the associated concentrators. Copper concentrate from these operations is refined to electrolytic copper at Legnica, Glogów I and Glogów II processing facilities. Mining is predominantly by room-and-pillar method, with minor amounts by cut-and-fill.
