Dashui gold deposit boasts its superlarge size. Based on the previous geological research, the quantitative regulation of resource growth has been revealed by studying the multifractals and grade-tonnage relation from geological data of ore-bodies. The ore-body lengths are subjected to single fractal distribution, while tonnages vs grades relation can be better fitted to the exponential function or linear function. With the multifractal characteristics of double-logarithmic chart of tonnages vs grades and tonnage vs orebody resources, all the above show that, in the fractal metallogenic structure space, the growth of mineral resources in specific metallogenic phase was a nonlinear proliferation process related to self-organized optimization and its random makes the relation of tonnage vs grades tend to be exponential function, and the whole metallogenic process was the linear addition of multi-phase ore-body resources.
