Western Henan is an important base area of China's gold, silver, molybdenum, lead, zinc and polymetallic resources. In recent years, new ore deposits have been discovered in succession. Geologists' estimations of resources quantities in this area are quite different from each other. On the basis of geochemical blocks theory and through regional geochemical data processing and calculation, the authors delimited the boundaries of western Henan gold geochemical blocks and calculated their areas, amounts of metals available and mineralization rates according to different levels of gold, molybdenum content. Using calculating method to predict the amount of gold resources in western Henan, the authors obtained 2 445 t for total gold amount and 11.1 million tons for molybdenum. At present, proved reserves account for a very small proportion in forecast resources. Compared with anomaly ore-concentrated areas of the same level in the world, the proved resources of this area are obviously low. Therefore, it has considerable resource potential. Source
