Santa Rosa-Huantajaya District, Iquique Province, Tarapacá Region, Chile

Vein-type silver deposits, hosted by Middle to Late Jurassic limestone strata that are intruded by dioritic and andesitic dykes and sills with local skarn development.

The Santa Rosa-Huantajaya district is an old mining district, which has been exploited intermittently since colonial times. It was an important silver producer by the end of the 19th century and in the early 20th century, but has been abandoned since 1942.

The deposits were explored to a depth of around 500 m. The exploited ores came mainly from the oxidation zone, which extends to a depth of around 100 m, and from a well-developed supergene enrichment sulphide zone, extending from 100 m to 400 m depth. The hypogene sulphide ores occurring below were not extensively mined.
