The Yinzishan Au deposit is hosted by the Silurian–Devonian Da'aozi Formation, which is comprised andesitic–dacitic volcaniclastic tuff, volcanic breccia, and less dacite. Middle Triassic clastic rocks and massive limestone, as well as Jurassic continental siltstone, are also exposed in the Yinzishan deposit. The Yinzishan deposit has a total reserve of ≥ 20 tonnes (t) Au. The individual orebodies are generally 0.35 to 17.51 m thick and 175 to 210 m long, extend up to 300 m down-dip (35–80° NW), and have grades ranging from ∼ 1.44 to 32.44 g/t, Au (avg ∼ 8.90 g/t). Four alteration/mineralization stages were recognized: the quartz–pyrite stage (S1), quartz–sulfide stage (S2), quartz–pyrite–telluride stage (S3), and quartz–carbonate stage (S4).
