| Abstract: | The application of ground high-precision magnetic measurement to the reconnaissance of one gold mine in eastern Shandong is briefed. After the large scale ground high-precision magnetic measurement and preliminary engineering testing,more than 20 shear structures were identified, 4 prospects for gold prospecting were outlined, and ore bodies over pay grade were met in 6 out of 8 drill holes. The ground high-precision magnetic measurement is an effective and feasible means for exploration. |
| Keywords: | high precision magnetic measurement deformation str ucture gold prospecting and prediction |
