Abstract: Based on field geological and mineral survey, and geological data collected from the western Negros, Philippines, it is analyzed the regional geological backgrounds, geological condition of mineralization and mineralization controlling factors of the copper and gold deposits in this area. The result shows that the?porphyry?copper deposits and hydrothermal gold deposits?are related to?Negros arc magmatic belt, mainly controlled by regional faulted structural fracture zones, diorites and Cretaceous volcanic clastic rocks, and the similar positions or nearby areas are favorable locations for prospecting copper-gold deposits, which having important significance for further prospecting for porphyry copper deposits and hydrothermal gold deposits in the future
