Gold occurs in a few geological formations in Poland. The gold deposits were actively prospected and exploited at least since early Middle Ages. At present gold is extracted only from copper-silver deposits mined in the area of the Fore-Sudetic Monocline. Gold occurs mainly in sediments of the oxidized facies, mainly in rocks of the Weissliegendes Sandstone of the Rotliegend and lower parts of the Zechstein copper-bearing shales. Gold is recovered in the course of technological processing of sulfide ores. In 2016, 402 kg of gold were recovered from Polish sulfide Cu-Ag ores and 3,539 kg of gold taking into account imported inputs.
The gold and arsenic mine at Złoty Stok, closed in 1960, was the last active gold mine in the Sudety Mts. Proven gold resources of the Złoty Stok deposit were estimated in 1954 at 2,000 kg in anticipated economic resources of the ore and 490 kg in the anticipated subeconomic ones. The mean content of gold is 2.8 g/t of ore.
Prognostic and perspective resources of gold are estimated at almost 350 tonnes*.
