| Result | GEOCHEMICAL SURVEY OF 75 HECTARES CONSISTING OF 890 SOIL, 525 ALLUVIUM, 916 ALTERED ROCK, AND 12 WATER SAMPLES INDICATED CU AND MO DISPERSION HALO VALUES WERE 50-100 PPM MO AND 300-600 PPM CU. GEOPHYSICAL SURVEY (RESISTIVITY AND IP) INDICATED ABOUT 10-30 VOLUME % OF DISSEMINATED SULFIDES AT DEPTH OF 16M. SIX HOLES DRILLED TOTALLING 509 M INDICATED 3 TYPES OF SULFIDE DEPOSITS: DISSEMINATED PYRITE, MASSIVE PYRITE, AND DISSEMINATED CHALCOPYRITE |
