Examples
-
The exposed mineralization exhibits characteristics that are typical of productive high-sulphidation epithermal gold deposits, including vuggy silica, multi-stage episodic hydrothermal breccias, colloform and crustiform banded quartz, and deposition of native sulphur, alunite, barite, copper sulphates, sulphides and sulphosalts, limonite and boxworks after sulphides.
-
The western half is dominated by banded quartz - calcite veins with colloform-crustiform textures.
-
Veins are typically banded quartz-chalcedony colloform - crustiform banded with quartz - carbonate infill.
-
A high level of preservation of the epithermal system is indicated by colloform vein textures and wallrock alteration characterized by low temperature carbonate minerals and illite-smectite clays.
-
Bladed quartz after calcite, adularia and colloform banded silica veins along the trend are indicative of boiling within the hydrothermal system creating conditions conducive to gold and silver mineralization.
