INTRODUCTION



Geophysical survey as a tool in modern day mineral exploration have found useful applicability all over the world. The Philippines, aware of the usefulness of geophysics in mineral exploration and because it abounds in mineral resources still unexplored and untouched inspite the operation of several low-grade porphyry copper mines decided to accelerate the discoveries of more mineral deposits. The acquisition of the Philippine Bureau of Mines of geophysical equipment, particularly Induced Polarization (IP) which was found most suitable
for the determination of low-grade sulfide deposits including those of copper will greatly help the country’s search for more commodity to enhance the growth of its economy.

This paper presents the progress and status of mineral exploration projects covering mainly geophysical and airborne surveys conducted by the Philippine Bureau of Mines during the past five years. These projects are herein classified as: (1) land geophysical survey (mainly Induced Polarization and related technique) and (2) the airborne magnetic survey. An insight into the field methodology is presented for the different areas covered by the survey including instrumentation and data acquisition. A summary on the results for each area is given and
their corresponding significance.
