The large Late Triassic Erdaokan silver deposit is discovered in Duobaoshan ore concentration area of Duobaoshan island arc in Nenjiang-Heihe area, and the exploration in the deep part of Tongshan deposit also makes a great breakthrough. The Late Triassic Mengdehe gold deposit is found in Keluo-Xinkailing tectonic melange belt, and the gold mineralization in the deep of Sanhetun goldfield periphery as well. The small Early Cretaceous Baoquan copper deposit is discovered in Taxi magmatic arc. These deposits are consistent with regionally delineated geochemical anomalies with obvious ore-forming regularity. Based on the new discoveries of copper and gold deposits, the paper summarizes the latest prospecting progress in Nenjiang-Heihe area in recent years, pointing out the next exploration direction and suggestions for future prospecting and providing reference for the upcoming strategic prospecting deployment.
