El Aguilar Mine: An Ordovician Sediment-Hosted Stratiform Lead-Zinc Deposit in the Central Andes

摘要: El Aguilar mine is located along the eastern slope of north-south range in Humahuaca department Jujuy province, Argentina, at approximately 23° 12′S latitude, 65°42′W longitude, an elevation 4450 m above sea level. 1900 km from Buenos Aires by rail, and 900 La Paz, Bolivia. At present leading Argentinian producer nonferrous ores, generating 2000 to 2200 t/day crude ore containing 5.5% Pb, 6.2% Zn, 60 110 g/t Ag. The main parameters show 2 volume 30 × 106 t (production + reserves), average combined grade 18% (Pb Zn+Cu). This deposit represents largest Paleozoic lead-zinc mineral concentration South America.
