About Daye District
Daye District in Hubei is one of the oldest copper-producing regions in China, with mining records dating from the Three Kingdoms period (~220 CE). The Tang Dynasty expanded copper production here, and modern operations now extract iron, copper, and zinc-lead ore. For collectors, Daye produces excellent galena, pyrite, and combination specimens with calcite and sphalerite.
Mining History
Mining at Daye began under the Three Kingdoms (~220 CE) and grew under Tang Dynasty copper coinage. The district was central to the early Industrial Revolution in China, supplying the Hanyang ironworks. Modern operations are run by Daye Iron-Steel Group and adjacent Pb-Zn mines; specimen recovery favors the upper oxidation zones.
Signature Specimens
Galena cubes 2-6 cm with mirror-bright faces, often with sphalerite and calcite. Pyrite cubes and pyritohedra. Less famous but consistent: rhodochrosite scalenohedra and rare supergene phosphates from upper-level ore.
