Ancient and modern 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.
No mines actually exist in Roşia Montanã (Verespatak. The Roşia Montană Area has been mined for Gold since the Copper Age (5300 to 1700 BC). During this age mining was entirely alluvial. This form of mining continued into the Bronze Age (3500 to 1200 BC) and then into the Early Iron Age (1200 to 550 BC). Roşia Montană Quartz vein lode Gold mining is speculated, in literature, to have begun in the late Bronze Age using trench/pit techniques. In the Dacian Age (1st Century AD) lode Gold mining began in earnest in Romania. Roşia Montană is the oldest permanent Roman mining settlement in Romania (about 1880 years old) then called “Alburmus Maior.” More accurately, according to Roman Wax Tablets found in the Cătălina Monuleşt gallery in the Coş Mine, the exact founding date was February 6, 131! Numerous major Mines have existed over the ages in the Roşia Montană area. Cârnic, Cetate, Cârnicel, Carpeni, Găuri, Zeus, Coş, Orlea, Ţarina, Piatra Corbului, Igre, Lety, Jig-Văidoaia, and Roşia Poieni (discovered in 1978) are all major Mines within an area less than 5 Km of the village of Roşia Montanã. It is rare to see anything but Roşia Montanã (Verespatak) on any older label. That is the reason why everyone assumes that Roşia Montanã (Verespatak) is a Mine and all specimens labeled Roşia Montanã (Verespatak) come from that Mine. Major corrections are needed for Alba and Hunedoara Counties.

Important note: This table is based only on rock and mineral ages recorded below and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.

1000 - 1600 Ma
|Mesoproterozoic intrusive and metamorphic terranes|
Age: Mesoproterozoic (1000 - 1600 Ma)
Comments: Mixtures of metamorphic and intrusive or plutonic rocks, tracts known as crystalline, migmatitic terranes, moderately to highly metamorphosed rocks of unknown origin with or without intrusions. This classification is inherently prone to variable interpretation, as other compilers might distinguish some packages by their metamorphic or gneissic protoliths, and the associated age ranges may be more variable.
