Deposit Type

  • Porphyry
  • Vein / narrow vein


Summary:

The Carmen de Andacollo orebody is a porphyry copper deposit consisting of disseminated and fracture-controlled copper mineralization contained within a gently dipping sequence of andesitic to trachytic volcanic rocks and sub volcanic intrusions. The mineralization is spatially related to a feldspar porphyry intrusion and a series of deeply-rooted fault structures. A primary copper-gold sulphide deposit (the “hypogene deposit”) containing principally disseminated and quartz veinhosted chalcopyrite mineralization lies beneath the supergene deposit. The hypogene deposit was subjected to surface weathering processes resulting in the formation of a barren leached zone 10 to 60 metres thick. The original copper sulphides leached from this zone were re-deposited below the barren leached zone as a copper-rich zone comprised of copper silicates (chrysocolla) and supergene copper sulphides (chalcocite with lesser covellite). Carmen de Andacollo deposit has “hybrid” features with elements of Porphyry Copper and Stratabound deposits. The structural domain model consists of the following main faults, sorted by relative age from the oldest to the youngest: 1) Syn-Mineralization: Carmen Fault and Hermosa-Twila-Andacollo Set. 2) PostMineralization: NS and NE Faults. Six big configurable lithology groups were identified: Lower Volcanic Unit, Upper Volcanic Unit, Intrusive Rocks Unit, Breccia Unit, Undifferentiated Rocks, and gravels. Nine mineralization events associated with nine alterati ........
