Jáchymov (St Joachimsthal), Jáchymov (St Joachimsthal) District, Krušné Hory Mts (Erzgebirge), Karlovy Vary Region, Bohemia (Böhmen; Boehmen), Czech Republic

A classic, rich vein-type Ag-Co-Ni-Bi-U deposit.

Jáchymov was founded by count Štěpán Šlik in 1516 in the place of former settlement Konradsgrün. The first known prospecting was done in 1510, the first mentioned mine was started in 1512 (mine of three wise men - Tří králů) - its opening still visible behind the house No. 496. The first find of silver was done after striking the Fundgrubner vein.
Abundant silver deposits lead to fast expansion of mining industry and whole town of Jáchymov ("silver rush") - after four years in 1520 - 4 963 inhabitants, in 1533 - 18 000 inhabitants - the second most populated town in Bohemia after Prague (compared to current 3 333 residents in 2010). In 1524 there were 613 mines and shafts operated. The mined silver was minced to famous coins named after the town (Joachimsthal) as Thaler (Talero, Tolar) later giving name to Dollar. Between 1527 and 1531 worked in Jáchymov Georgius Agricola as a town physician. In the time of greatest prosperity of silver mines (1516-1600) app. 350 tons of Ag were mined.

NOTE: A fine collection of Jachymov minerals was assembled in recent decades by Mr. Josef Vajdak of Massapequa, New York. This private collection was disbursed starting in January, 2009.
