Abstract:

Through research of deep prospecting in Chaihulanzi gold deposit，starting with raw data collecting from the field，focused on the ore body characteristics，summary its occurrence law，and then complete a position prediction of the deep ore bodies.The prediction had been verified by drilling confirmed was a deep prospecting breakthrough.The position of the deep orebody was judged mainly according to the geological conditions of the fault structure and the ore body characteristics analysis，the results showed that the lateral trending of center of the knob tectonic，the intersection of orebodies with different trends，is the lateral trending of the orebodies，the orebody developed to the deep along the direction of the intersection.Thus，we determined the predicted target：Firstly，a 315° trend orebody with key forecast positions below the elevation of 700 m，between south of 18 lines to 33 lines；secondly，a nearly EW trend orebody with the key predict positions below the elevation of 700 m between east 5350 line to 5950 lines.Drilling results verified that mineralization within the target range was good，obtaining a total of 4 511.39 kg of gold metal （333），1.436 million tons of ore.The 1# orebody had 713.84 kg of metal content，196 400 t of ore；4# and 8# orebody had a metal content of 797.55 kg，1.2395 million tons of ore，respectively.

Key words: Orebody occurrence characteristics, Deep metallogenic prediction, Chaihulanzi gold deposit, Inner Mongolia
