   Gold Hill Prospect: Soil geochemistry surveys (1,063 samples) by Mindoro in 1997 defined strong, northeasttrending copper anomalies (greater than 200 ppm copper and up to 1,700 ppm) semi-continuously over an area of 1.5 km by 1.0 km, termed the Gold Hill Prospect. There are two coincident gold anomalies (greater than 50 ppb and up to 10,100 ppb), extending over 1.0 km by 0.4 km, and 0.4 km by 0.4 km. Systematic rock sampling of abundant old gold mines and workings in the area has not yet been undertaken. However 54 rock samples, mostly grabs of float and outcrop varied from 0.01 to 16.2 g/t gold (average 0.4 g/t). Copper mineralization was visually and petrologically identified in numerous locations, however, copper analyses were not performed.

    Structural Controls of Boyongan and Tapian San Francisco: Mineralization in the District is controlled by the intersection of northeast-southwest trending crossfaults with splays of the northerly Philippine Fault System. A major northeast-southwest trending fault bounds the Boyongan/Bayugo discoveries along their northern side and extends directly into the Tapian San Francisco Project, where it controls alteration and mineralization.
