AURORA MINING
English Version
The Santa Barbara, Santa Barbara 1 and Santa Barbara 2 properties are considered to be related with the San Francisco de Los Andes mining project. They are located on the eastern margin of the geologic province of Cordillera Frontal, in the department of Calingasta. These mining concessions are located 150 km northwest of the city of San Juan.
The historic San Francisco de Los Andes mine initiatedproduction in the 1940s as a bismuth mine.In the 1970s, work was focused on production of copper and bismuth. In the ’90s, Minera Aguilar drilled the area with promising results.In 2019, Aurora Mining conducted exploration work that confirmed previous results indicating continuity of mineralizationand identified new prospective targets.
The Santa Barbara project is associated with tourmaline-quartz breccia bodies and quartz veins preferentially intruding Carboniferous sedimentary host rocks. The genesis of these breccia bodies is linked to granite-granodiorite intrusions that are part of the Permian-agedTocota batholith. The target metallic elements include gold, silver, copper and base metals, while the pathfinder elements are arsenic, bismuth and antimony.
