The Huzagaitu porphyrytype molybdenum deposit was found by verifying the geophysicalgeochemical anomalies, and the ore bodies mainly occur near the contact zone between the early Yanshanian finegrained granite and the middle Ordovician Hanwula rhyolite. In the mining area, the geophysical and geochemical anomalies have a good combination and a clear hierarchical structure around the granite body. The center of the anomaly is a positive high magnetic field, and outwards there are in succession negative low magnetic field and soil anomaly area, positive low magnetic field and IP anomaly area, and negative normal magnetic field. The geophysical and geochemical anomalies exhibit a good indication of rocks and ore bodies. The magnetic anomalies reflect the distribution of the orebearing granite rocks and the mineralization alteration zones, the soil anomalies indicate the positions of the molybdenum ore bodies, and the IP anomalies indicate the locations of the molybdenum ore bodies and the rhyolite rocks with strong pyritization near the contact zone. Some anomalies were verified with trenching and drilling, 3 molybdenum mineralization belts were discovered, and 5 ore bodies and 3 mineralized bodies were found. The controlled molybdenum reserves have already reached the medium size, and the ore deposit is likely to become a largesize ore deposit.
