Aeromagnetic, gravimetric and electromagnetic surveys could help you discover a new deposit and characterize its potential extension.

Abra is a large, low-grade, stratabound Pb-Zn-(Cu-Au) SEDEX deposit, located in Western Australia. The deposit lies at a depth of 270 m.

An aeromagnetic high, superimposed on a gravity high was key to the discovery of this deposit. The source was found to be disseminated and vein hosted sulphides.

A Borehole TDEM survey was undertaken to search for highly conductive zones within or peripheral to the main body which may indicate zones of higher-grade mineralization.

The stratabound ore body and underlying stringer zone are weakly and uniformly conductive. The conductivity anomaly is explained by the known source and no additional mineralization was detected.
