The authors have studied the statistical characteristics of China's molybdenum deposits to establish the grade‐tonnage model based on the data updated to the end of 2010. The results showed that each type of China's molybdenum deposits complied with Lasky's law approximately and the characteristics of grade‐tonnage model obey the lognormal distribution. However, there are poor correlations between grade and tonnage respectively. Ultimately, we aimed to fit the grade‐tonnage model through the known distribution function, draw the cumulative probability curves, and evaluated undiscovered mineral resources of China's molybdenum deposits by means of Monte Carlo simulation integrated in MRAS.
