It has previously been used for non-geological problems, but here we demonstrate its use in ore prediction. Our example is from our work on known Cu deposits distributed in the Panzihua-Xichang region of Sichuan Province to set up a Grey prediction model for an unknown deposit in a similar type of environment. The following steps were carried out: (1) a sift selection was first made by logical information processing of the initial data from the known deposits, (2) data on seven deposits belonging to the same general rock type were obtained, and (3) a Grey prediction model was set up and used to make predictions about an unknown deposit in the same type of environment.
