The operations include the Pomorzany and Olkusz mines, the Olkusz mill. The mill produces a zinc concentrate, a lead concentrate and from May 1997, a high grade zinc "bulk" concentrate has been produced as feed to the ISF smelter Miasteczo Slaskie. The zinc concentrate goes to the integrated Boleslaw zinc smelter, a few kilometres away and the lead concentrate is exported.
