The Establishment of Geological Model and Totalresources Estimate of the Zaozigou Gold Deposit, Hezuo, Gansu Province

The Zaozigou gold mine is located in the transition zone between north fault-fold belt and central rift of western Qinling fold belt. This article analyzes the gold deposit geological features, the geological characteristics of the orebody and the orebody grade variation characteristics to establish the deposit descriptive model, variogram model and gold grade fractal distribution model. Finally, the direction of deep mine exploration is discussed and the total of mine resources is also estimated.
