The Baiyin copper deposit is located in Gansu Province in northern China.   Copper was first mined here during the Ming Dynasty (1368-1644), although the deposit was not re-discovered until the 1950's.   It is a volcanic hosted massive sulphide deposit (or group of deposits) occurring as ironstone capped supergene mineralisation.

The country rocks comprises a 2000 m thick Silurian - Devonian succession of greywacke and shallow marine eruptives of calc-alkalic, keratophyre-spilite, with intrusions of sodium rich acid to basic rocks.   The immediate host sequence comprises quartz keratophyre tuff and quartz keratophyre, with strong silicification, sericitisation and potash feldspar alteration accompanying the ore.

The primary ore minerals are mostly pyrite and chalcopyrite with minor spalerite, galena, pyrrhotite and cassiterite.

A new deposit 80 km from Baiyin has proven reserves + indicated resources of 10 Mt at an un-specified grade.
