The application and significance of IP sounding to the blind-ore forecast ——Taking F40 fault mineral prediction of Xiahaoping gold deposit for example
Abstract：Reasonable geological interpretation is the premise and the key to blind orebody forecast by IP sounding. The prediction of Xiahaoping gold deposit is a good instance. The gold deposit has low resource reserves, 80 - 200 m fault throw, weak outcrop mineralization and significant differences of ore and rock properties. This paper chooses symmetric four-stimulated electrical sounding as a main prediction method. The point distance is 50 - 100 m and 25 m partly. By treating the power reflection coefficient and resistivity ratio, it concluded that there is blind orebody in the depth of 400 m below 700th point. The polarization is obviously ab- normal and close to the tectonic zone. It is considered that it is the reason why the mine leads to the abnormality by comparing with identical deposits in the region. And it is judged that there is blind orebody that exists in the depth of 400 m below 700 points according to the result of geophysical prospection. The gold orebody may be 0.8 m thick, and the grade is 3.24 × 10^（-6）. The forecast has been confirmed by the drilling hole.
