The trench exploration was carried out on the quartz veins of the Tanggung area of Java, Indonesia. The chemical values of quartz vein samples for hydrothermal alteration zones in this area are defined such as over values of Ag : 2~190 ppm(Celak); 2~41 ppm(Cilangkap), Au : 21~17,400 ppb(Celak); 24~91,100 ppb(cilangkap), Cu : 9~3,340 ppm(Celak); 2~1,600 ppm(Cilangkap), Pb : 60~52,900 ppm(Celak); 16~2,960 ppm(Cilangkap), Zn : 12~13,950 ppm(Celak); 14~1,520 ppm(Cilangkap), respectively. Two drilling areas, Mt. Subang area(Celak area) and Mt. Cilangkap area(Cilangkap area), have been chosen based on the factors such as, geologic settings associated with gold mineralizations, highly anomalous areas revealed by geochemical survey such as chenmical anaysis of ore and soil, trench exploration, statistical processing of the chemical analysis, and petrographic studies of igneous rocks related to its mineralization, and graphic presentation of anmalous areas.
Keywords trench exploration, hydrotermal alteration, gold mineralization, drilling, Indonesia
