Gravity, Magnetic & Gpr Surveys For Massive Gold Deposits At A Philippine Treasure Site
Ralph Pollister Soule · 20th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems · 2007
Beginning in December 2002 GeoPotential Philippines, Inc. (GPI) in conjunction with the International Recovery Group Philippines, Inc. (IRGPI) conducted a series of geophysical surveys over several potential treasure sites in the Philippines. The purpose of the geophysical surveys was to locate massive gold deposits that had been buried by the Japanese military during the occupation of the Philippines in World War II. This paper discusses the geophysical surveys conducted at one of the treasure sites (Figure 1 INDEX MAP) called the “Waterfall Site”. At the Waterfall site Gravity, Magnetic and Ground Penetrating Radar (GPR) Surveys were conducted to search for 250 metric tons of Gold buried at a depth of 10 to 15 meters. An initial Gravity Profile indicated a possible massive Gold deposit. The GPR Survey produced an anomaly indicative of a buried chamber. However subsequent excavation of the feature indicated a hoax. The follow up Gravity Survey produced a Gravity Anomaly consistent with a massive deposit of gold. Excavation at the Site is currently suspended due to environmental and political concerns.
