Porphyry copper-molybdenum-gold deposits in alkali-rich porphyries of the Machangqing multi-phase composite pluton. The ore bodies are structurally controlled and consist of veins and fine veinlets in syenites, porphyroid alkali granites, Lower Ordovician hornstones and skarns. Altered rock type and karst-hosted laterite type gold mineralizations occur outside of the contact zone.

The ore field straddles the border between Midu and Xiangyun counties. Deposits in Xiangyun County, in the northeastern part of the ore field, are mainly worked for gold.
