The four-year work program on the mineral resources development of Samar and Leyte Islands was completed and the project was successful in assessing and evaluating the mineral potential of both islands, as well as in providing basic geological data needed for any infra-structure development of both islands.

Among the highlights of the project are the discovery of bauxite deposit and the delineation of copper prospects in Lawaan, Wright, Samar where the United Nations entered into contract with the Philippine Government to finance and undertake jointly with the Bureau of Mines and Geo-Sciences the exploration work in the area. Other mineral prospects of interest were the manganese deposit in San Jose de Buan, the copper prospect at Midway-Lunoy-Bunot, the coal deposit in Giporlos, the gold prospect at Pana-on Island, the phosphate rock and asphalt
deposit in northwestern Leyte and the copper prospect at Curajo-Palo in Leyte. Several other metallic and nonmetallic prospects were also investigated but due to unfavorable result of geological finding no further studies were recommended on these prospects.

The activities undertaken during the four-year program were reconnaissance geological survey of Samar and Leyte Islands, reassessment of all known prospects in both islands, detailed geological, geochemical and geophysical surveys of promising deposits and diamond drilling of two copper prospects, one in Samar and one in Leyte, and drilling of the
phosphate deposit in Bo. Bantique, Isabel, Leyte.
