Six personnel of the Mines and Geosciences Bureau IV-CALABARZON conducted geological verification and assessment of a proposed Minahang Bayan (small-scale mining area) in Brgy. Mapulot, Tagkawayan, Quezon on June 15-29, 2021 to determine if the area is technically and economically viable for small-scale mining operations.

The said activity aims to determine areas where the minerals present can provide sustainable livelihood to interested small-scale miners in the nearby community and develop a cooperative that practices safe and environmentally compliant mining in the area.

It was conducted under the supervision of Fidel Zepeda, Senior Geologist, and other technical personnel from Mine Management Division and Geosciences Division, namely: Luigi Pernia, Engineer II, Ronn Christian Castillo, Engineer II, Michael Angelo Escober, Geologist, Neil John Tadeo, Chemist, and Allan Rivera, Cartographer.

Geological mapping and random sampling were conducted within and in the vicinity of the proposed area, specifically at sites where gold mineralization was reportedly present. Samples collected were subjected to laboratory analyses with pending results, however, the presence of excavations and reported panning activities suggests that the area has potential for gold mineralization.
