Prediction models for mineral resources provide an analytical foundation and method to express the results of resource evaluations. The project "China National Mineral Resources Assessment Initiative" was conducted during 2006-2013, with the aim to determine the location, quantity, and quality of 25 important mineral resources occurring at depths of < 1 km. There are currently 80 integrated prediction models on the scale of III-level metallogenic belts in use across China. The Huangshaping Pb-Zn polymetallic deposit, Hunan province, China, is used as a case study to establish methods and processes for developing a mineral resource prediction model that would be used for exploration targeting. The construction of prediction models requires the development of a classification scheme for the proposed prediction method appropriate for the prediction area. An initial metallogenic model is quantitatively transformed to a prospecting model, and then a prediction model. The incorporation of additional methodology, analysis of a comprehensive geological database, and correlation of asymmetric information between the well-explored typical deposit area and regional prediction area, yield an integrated prediction model. This paper also discusses the prediction modeling theory, and presents 12 models used for mineral assessments.
