| Abstract: | The deposit was discovered in a 1: 200,000 scale aerial survey as a small-scaled weak magnetic anomaly. Later on, a gossan was discovered, under which copper mineralized basic rocks were found through drilling, but without productive ore body. A magnetic anomaly was found to the southeast of the gossan about 200m away by surface magnetic survey.After drilling exploration.compact massive copper and nickel ore was discovered.
According to main rocks and properties of the ore, methods of gravity survey, magnetic survey, induced polarization and chemical soil survey were selected to be used in the detailed prospecting within the ore field. The effect of geophysical and geochemical exploration is as follows:
1. Basic rock bodies overlain by the Quaternary system were discovered and prominent complex anomaly was gained. Based on the complex anomaly the shape in 2 and 3 dimensions were studied to direct correct planning of drilling.
2. Two small anomalies among a complex anomaly group of gravity, magnetism, electricity and geochmistry led to, discovery of productive ore bodies were found.
3. In section with prominent anomalies of gravity and chargeability and weaker anomalies of magnetism, but without prominent anomaly of geochemical soil survey, basic rock bodies with poor mineralization were found and proved in the depth of 200m by drilling according to apparent chargeability anomalies; and through further drilling work, productive ore bodies were found.
4. In the section with prominent gravity and chargeability anomalies, weak anomalies of magnetism, but without anomalies of chemical soil survey, ore-bearing rock bodies at the depth of 216.9m were found by drilling according to gravity anomaly.
Herein, the anomaly machinism of the ore deposit and the combination of pro-specting methods are also studied. |
