Roşia Montanã (Verespatak; Vöröspatak; Goldbach), Alba Co., Romania

Gold mines. A project by open-pit mining (by the Canadian investor Gabriel Resources) was abandoned in around 2007.
Breccia pipe/brecciated dyke, discordant veins in clusters.
Host rock: Dacite.

Alteration: adularization, sericitization, chloritization, argillization, silicification and pyritization.

The ore deposition at the Rosia Montana deposit evolved from an early Au-(Ag) low-sulfidation character to a late Ag-Te-(Ge-Au) intermediate-sulfidation character, and may be correlated with late magmatic pulses (Tamas et al., 2006).

Ancient gold mines on Mt. Kirnik, with well-preserved Roman galleries. The mining has started here about 2000 years ago.
Located about 4 km SW of Rosia Poieni.
