Porphyry copper-(molybdenum) deposit, hosted in monzonite porphyry and diorite porphyry. Most copper mineralization is in the monzonitic porphyry, which has a peralkaline chemistry with a porphyritic texture and massive structure. No significant mineralization is present in the volcanic country rocks of the Qi’eshan Formation. The deposit is relatively unexposed, but widens with depth. The mineralized orebodies have elongated geometries that parallel their monzonitic porphyry host stock. Drilling has identified mineralization to depths of 600–700 m, remaining open at depth. The Tuwu and Yandong deposits lie just 8 km apart, and drilling between them has confirmed additional mineralization.
