Late Tourmaline breccia
Poorly sorted, subangular, matrix-supported, polimictic tourmaline breccia. All fragments show different grades of sericitic alteration supported by tourmaline-silica matrix and minor concentration of fine-grained pyrite mineralization.

Basic Cu-supergene profile
Copper mineralization distribution within Cu-oxide-secondary enrichment transition zone related to intense sericitic background. Notice replacement grade of secondary sulphides over primary imprint.

Limonites horizon
Classic profile of leached horizon over poorly mineralized primary zone with sericitic alteration scarcely developed.
