Exploration geophysics as applied in the Philippines yield favorable results.

Aeromagnetic survey done by Hunting Geophysics, Ltd. defined several areas for probable iron occurrences. Subsequent prospecting efforts, including ground magnetic work in suggested areas revealed the presence of iron bodies. Elsewhere, ground magnetic work in iron properties helped evaluate the potential and promises of the areas. Several blind ore bodies were pinpointed.

Electrical method played a major part in discovering a sulfide ore body in Balabac Island. Airborne radiometry done by Hunting established several anomalies. One anomaly in Larap was proved to be caused by uranium mineralization. Lately a U.P. geophysicist demonstrated the use of seismic refraction method in probing the extension of chromite bodies. Gravity survey conducted on the Masinloc chromite deposits disclosed a few million tons of ore.
