Deposit COLOSSAL MINING IS MANAGED BY LEPANTO CONSOLIDATED MINING, PHILIPPINES. IN 1975, THE COMPANY COMPLETED DRILLING FOUR ADDITIONAL TEST HOLES, BRINGING THE TOTAL NUMBER DRILLED TO 11 IN THE LUM- BAY COPPER PROJECT. A PROSPECTIVE OREBODY 600 METERS LONG, 400 METERS WIDE AND 400 METERS DEEP HAS BEEN DELIN- EATED. EXPLORATION HAS REVEALED OTHER COPPER DEPOSITS WITHIN A FEW KILOMETERS OF THE CENTRAL LUMBAY DEPOSIT. 1975 - THE 24 KILOMETER ACCESS ROAD IS ALMOST COMPLETED. WHEN COMPLETED THE ROAD WILL ACCELERATE DEVELOPMENT OF THE OPERATION. PREVIOUSLY, MATERIALS HAVE BEEN AIRLIFTED IN AT TREMENDOUS EXPENSE. BESIDES DRILLING, THE COMPANY IS CARRYING OUT GEOCHEMICAL EXPLORATION AND GEOLOGIC MAPPING.
