OF 0.99 GPT AU AND 16.6 GPT AG AND 78 METERS OF 0.93 GPT AU AND 21.5 GPT AG, RESPECTIVELY. EACH OF THESE HOLES CONTAINED 1.5 METER THICK INTERCEPTS OF 161 GPT AU AND 44.5 GPT AU, RESPECTIVELY. 105 ADDITIONAL HOLES WERE DRILLED IN 1988. AN OREBODY CONTAINING 13.7 MILLION METRIC TONS GRADING 0.72 GPT AU AND 11.4 GPT AG WAS DEFINED BY JUNE 1988, AND THE DECISION TO DEVELOP THE MINE WAS MADE. IN 1989, 188 DRILL HOLES TOTALLING 20,591 METERS WERE COMPLETED. MINE CONSTRUCTION WAS DELAYED TO JANUARY 1989, PENDING COMPLETION OF AN ARCHEOLOGICAL MITIGATION SURVEY. ; ECON.COM: CASH OPERATING COSTS WERE $265/OZ AU IN 1989 AND Comment (Development): $197/OZ AU IN 1990. TOTAL OPERATING COSTS (INCLUDING DEPRECIATION AND AMORTIZATION) WERE $372/OZ AU IN 1989 AND $310/OZ AU IN 1990. THE PRECIPITATE PRODUCT FROM HEAP LEACHING IS TRANSPORTED TO THE SLEEPER MINE FOR PROCESSING INTO DORE. Comment (Development): THE EARLIEST PROSPECTORS WERE PROBABLY PREHISTORIC INDIANS WHO COLLECTED SILICA CHIPS FOR TOOLMAKING. THE FIRST MINING CLAIMS WERE STAKED IN THE AREA AROUND 1900. OLD PROSPECT PITS INDICATE NATIVE SULFUR, CINNABAR, AND OPAL WERE OF PRINCIPAL INTEREST. MINOR QUANTITIES OF AU AND AG WERE DISCOVERED IN THE 1930'S AND SEVERAL ADITS AND PROSPECTS WERE EXCAVATED IN A SMALL AREA 1 KM SSE OF WIND MOUNTAIN. PROSPECTING ACTIVITIES FOR SULFUR, CINNABAR, GOLD, SILVER, AND MONTMORILLONITE CONTINUED THROUGH THE 1970'S. IN 1979, TMB ASSOCIATES STAKED THE CORE CLAIM BLOCK. AMAX EXPLORATION, INC., LEASED THE PROPERTY IN 1980 AND DRILLED 10 HOLES. HOLES A-3 AND A-4 INTERSECTED A ZONE 76 METERS THICK THAT AVERAGED 0.79 GPT AU AND 25 GPT AG. AMAX RELINQUISHED THE PROPERTY IN 1982 DUE TO THE OVERALL LOW GOLD VALUES AND APPARENT SMALL SIZE OF THE MINERALIZED AREA. SANTA FE PACIFIC MINING CO. AND CHEVRON RESOURCES CO. HELD PARTS OF THE PROPERTY FROM 1983 TO 1986, AND DRILLED 31 AND 7 HOLES, Comment (Commodity): AG:AU RATIO APPROX. 15:1 METALLURGICAL TESTING INDICATES GOLD OCCURS ON MICROFRACTURE SURFACES AND IS NOT ENCAPSULATED BY SILICA, SUGGESTING GOLD DEPOSITION POSTDATES MOST OF THE SILICIFICATION. THE CLAY USED TO CONSTRUCT HEAP LEACH PADS, ETC.
