Structural Overprint Halo Model of the Predicted Blind
The structural overprint halo technique is applied to set up the model of the overprint halo in Baiyun gold deposit. The model was used as the guide to predict blind ore bodies at depth. 7 targets and 2 potential areas were located by the prediction. Drill operated at several targets hit ore bodies which are calculated to reserve about 10.6 t Au and the former medium sized Baiyun Au deposit becomes a large sized one now.
