2023
Gold occurring in various geological formations in Poland was a subject of a mining activity from at least the early Middle Ages. At present, gold is extracted only by copper-silver mines located in the area of the Fore-Sudetic Monocline, in Dolnośląskie Voivodeship. Gold occurs mainly in the oxidized facies sediments (in German Rote Fäule), mainly in rocks of the Weissliegendes Sandstone of the Rotliegend and in the lower parts of the Zechstein copper-bearing schists (Kupferschiefer). Gold is recovered in the course of a technological processing of sulfide ores and imported inputs. In 2023, 442 kilograms of Au were recovered from Polish sulfide Cu-Ag ores. Moreover, the Capital Group KGHM Polish Copper Combine S.A. produced 3,452.48 kg of TPM (Total Precious Metals – the sum of accompanying metals: gold, platinum and palladium) taking into account also imported inputs. Precious metals above mentioned constitute only minor part of the KGHM production, regarding the volumes, however they are of a significant economic importance when it comes to company’s profit. The KGHM Polish Copper S.A. – both from its own production and imported inputs – produced 5,735.50 kg of TPM, whereas the KGHM INTERNATIONAL LTD achieved the level of 1,262.80 kg of TPM – taking into account its own production and imported inputs. In the Sierra Gorda S.C.M there were 1,023.30 kg of TPM recovered in 2023 (own production and imported inputs).
The gold and arsenic mine at Złoty Stok, closed in 1960, was the biggest active gold mine in the Sudety Mts. Documented in 1954 gold resources of Złoty Stok deposit were estimated at 2,000 kilograms in the ore anticipated economic resources and 490 kilograms in the ore anticipated sub-economic ones. The mean content of gold in löllingite-arsenopyrite ore is 2.8 g/t of ore. This deposit was exploited after the Second World War in 1954-1960. During that period about 25% of documented resources were exploited.
In 2020, there was a geological documentation of a small deposit of gold ore in kaolin clays approved – the Mikołajowice deposit in Dolnośląskie Voivodeship. In the deposit there were anticipated economic resources in C category documented – they are equal 5,028.7 thousand tonnes of ore, 968.0 kilograms of metallic gold and 723.8 thousand tonnes of kaolinite; the anticipated sub-economic resources also documented in C category are equal 4,842.6 thousand tonnes of ore, 69.7 kilograms of metallic gold and 435.8 thousand tonnes of kaolinite. The deposit is formed by one bed of kaolin weathering loams with quartzitic debris – the result of quartz-micaceous schists and quartz-feldspar veins weathering processes. The average content of gold in the anticipated economic ore was geochemically determined at 172.4 ppb, whereas in anticipated sub-economic ore at 14.4 ppb. In 2023, the given deposit’s resources have not changed.
The prospective resources of gold in Poland are assessed to be equal 419.2-431.8 tonnes, whereas the prognostic resources to be equal 34.3 tonnes*.

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 exploited 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 2015, 431 kg of gold were recovered from Polish sulfide Cu-Ag ores and 2,703 kg of gold taking into account imported inputs.
The gold and arsenic mine at Złoty Stok, closed in 1960, was the latest active gold mine in the Sudety Mts. Proven gold resources of the Złoty Stok deposit were estimated in 1954 at 2,000 kg of anticipated economic resources of the ore and 490 kg of the anticipated subeconomic ones. The mean content of gold is 2.8 g/t of ore. Złoty Stok deposit was exploited in the years 1954-1960 which resulted in extraction of 25% of its resources. The resources remaining in the deposit are estimated at 537,000 tonnes of ores yielding 19,600 tonnes of arsenic and 1,500 kg of gold. The deposit has been abandoned because of a very limited demand and high toxicity of arsenic. At present the chance for reactivation of this mining operation is negligible. Gold was also extracted from hydrothermal gold-bearing quartz-sulphide veins at Radzimowice, Klecza-Radomice, Czarnów and Wądroże Wielkie. Besides, in Lower Silesia region placer gold was also a subject of extraction from Cenozoic sands and gravels. The gold-bearing sediments occurred in numerous river valleys (e.g. Bóbr, Kwisa, Kaczawa, Nysa Łużycka) in the vicinities of Złotoryja, Lwówek Śląski and Bolesławiec.
Prognostic and perspective resources of gold are estimated at almost 350 tonnes*.
