Qualified comments: |
(Applies to: discovery and development) A group of 15 veins; worked by artisanal miners to extract the Cu oxides which contain traces of Au; the veins have a potential ranging from a few thousand to tens of thousand tonnes.
(Applies to: location and access) Locations was taken from the location of Atiquipa in Google Earth, and is very approximate. |
