This mineralization takes place as breccia matrix fill, disseminations and veinlets in altered andesites. |
The highly fractured felsite is cemented by veinlets of chrysocolla and malachite with minor amounts of cuprite. |
Some of the material contained micaceous masses of specular hematite associated with quartz, epidote, and numerous veinlets of calcite. |
The gold is associated with pyrite, pyrrhotite, quartz in veinlets, amphiboles and garnets. |
Weak to moderate quartz and quartz-ankerite veinlets were observed in the drill holes along with locally weak to moderate argillic alteration. |
The ore zone is a combination of veinlets, lenses, and nests of pyrite and quartz. |
