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.
