It has been operational since 1974 and produced more than 21Moz of silver in 2011. The mine exploits the copper and silver resources of the Rudna mineral deposit. It is an underground mining operation consisting of 11 shafts and 13 mining sections at a depth of 950m to 1,150m. It employs room-and-pillar method with hydraulic backfilling.

The reserves of Rudna and 50% of Deep Glogów, if combined, will be 587Moz, making it the third biggest silver mine in the world - "".
