Porphyry Cu-Mo-Au deposits, related to the Late Mesozoic adakitic porphyries of Fujiawu, Tongchang and Zhushahong that intruded Mesoproterozoic slate and phyllite. Only the Tongchang deposit is mined at a larger scale. A small scale operation is centered at the Fujiawu deposit, whereas the Zhushahong deposit is not presently worked. The Guanmaoshan gold deposit, located between the Tongchang and Fujiawu deposits, does also belong to the ore field.
The Dexing ore field is the largest porphyry copper ore field in China, with estimated reserves of 1.5 billion tonnes of ore grading at 0.43% Cu, 0.02% Mo, 0.16 g/t Au, and 1.9 g/t Ag.
Located southeast of Jingdezhen.
