Deposit status: prospect; Size category: small
Geologic province: Miocene-Pleistocene Andean Arc
Geologic subprovince: Puna Plateau
Geologic district: Arizaro Basin
Commodities: Cu; Au; Fe
Mineralization styles: breccia-fillings; veins and associated disseminations
Geological ages: Miocene (host rocks)
Miocene (mineralization)
Tectonic setting: continental arc-inter-arc; convergent; Formal name: Miocene-Pleistocene Andean Arc (host rocks)
Coincident features: intrusive core (Lindero intrusion is located 3 km NW of Arizaro intrusion; a NE-tending valley separates them); Coincident feature name: Arizaro Volcanic Complex
Regional tectonic structure: plateau uplift due to subduction-related crustal thickening (rapid uplift and continental volcanism continued to Pleistocene) Tectonic structure name: Miocene Andean Arc
Metallogenic signatures: Fe-Cu-Au
Radiometric ages: Object dated: Host Rocks; Age - Ma: 16.75; +0.35; -0.35; Dating method: Ar-Ar; Concentrate: whole rock; Source rock: porphyritic intermediate intrusion; Formal name: intrusive event; Event dated: host rock; Interpretive comment: age of relatively unaltered intrusive rocks indicates the time of emplacement ; Reference: Dow, R. J.; Hitzman, M. H., 2002: Geology of the Arizaro and Lindero Prospects, Salta Province, Northwest Argentina: Mid-Miocene Hydrothermal Fe-Ox Copper-Gold Mineralisation; Section The Americas, in Hydrothermal Iron Oxide Copper-Gold and Related Deposits: A Global Perspective, Volume 2, Edited by Porter, T.

Object dated: Mineralization Style; Age - Ma: 15.21; +0.11; -0.11; Dating method: Ar-Ar; Concentrate: biotite; Source rock: potassic alteration zone; Formal name: alteration zone ; Event dated: alteration; Interpretive comment: age is close to that of the host rock and of biotite in the Arizaro prospect 3 km to the southeast; Reference: Dow, R. J.; Hitzman, M. H., 2002: Geology of the Arizaro and Lindero Prospects, Salta Province, Northwest Argentina: Mid-Miocene Hydrothermal Fe-Ox Copper-Gold Mineralisation; Section The Americas, in Hydrothermal Iron Oxide Copper-Gold and Related Deposits: A Global Perspective, Volume 2, Edited by Porter, T.

Qualified comments: (Applies to: discovery and development) Discovered in 2000 during gelogical mapping of the area of Arizaro prospect found in 1999; 1100 m of trenching returned an average grade of 0.66 g/t Au and 0.13 % Cu, in a semicircular zone 900 x 70 m.
