The Duotoushan Fe–Cu deposit is classified as a medium-sized iron deposit according to Chinese classification (0.1–1.0 Mt metal reserves), lacks defined reserves, but exhibits a grade of 45–53 % Fe and 0.7–1.0 % Cu. At Duotoushan, the exposed strata primarily comprise andesitic to dacitic tuff or lavas and brecciated tuff, with orebodies being predominantly hosted within andesitic tuff. In the Duotoushan deposit area, it comprises seven stratiform orebodies that range from 50 to 248 m in length and 4 to 70 m in width. At Duotoushan, iron mineralization occurs as massiveness and dissemination, whereas copper mineralization is sub-economic and can be recognized as disseminated and vein-type ores.
