  Rezumat:  At the beginning of the 2ndcentury A.D. a new economic space opened in the northeastern extremity of the Roman Empire. Rome acquired Dacia after the Trajanus''s victorious campaign in 106 A.D. against Dacian king Decebal. The assets of this new territory were based on the presence of important metalliferous resources among which, gold and silver were the most important ones. Located within the Apuseni Mountains, the Roşia Montană gold-silver ore district is one of the richest in Europe. The mining perimeter has about 6 km and still remains extremely rich. In the ancient site of Alburnus Maior, located along the Roşia Valley, the mining activity developed mainly after the 2ndcentury A.D. According to some estimation, initially about 1000 t of gold and 3000 t of silver were concentrated within this ore deposit. After twenty centuries of almost continuous exploitation of the Roşia Montană epithermal ore deposit centred on a phreatomagmatic breccia pipe structure (the Cetate breccia), the reserves would still be of more than 300 t of gold. These reserves were recently pointed out by S.C. Roşia Montană Gold Corporation S.A., a Romanian-Canadian mining company which is preparing an exploitation in a large open pit. This mining project comprises the exploitation of the ore bodies hosted by the Cetate and Crnic massifs, which surround the actual village. These two massifs, as well as other areas of the mining perimeter, contain important archaeological vestiges of the pre-Roman, Roman and medieval times. This is the reason why very important archaeological rescue diggings and studies were started before the initiation of the exploitation activity. ...
