The Gumyoshevsky mine (Russian: Гумёшевский рудник, romanized: Gumjoshevskij rudnik), also called Gumeshki, Gumeshevsky or Gumishevskoye mine is a copper mine located in the town of Polevskoy, in Sverdlovsk Oblast of Russia.
It has estimated reserves of 48.5 million tonnes of ore grading 1.02% copper.
In 1758 large deposits of oxidized copper were discovered there.
In the 18th century Gumyoshevsky mine represented the largest copper reserve of the Ural Mountains, and gained fame as the major supplier of malachite.
For a long time it supplied ore for Polevskoy Copper Smelting Plant (1724–1870).
