Comments

Comment (Economic Factors): DEVELOPMENT THE UNDERGROUND MINE REQUIRED 4 YEARS OF PREPRODUCTION. THIS INCLUDED THE SINKING OF THE NO.2 REC TANGULAR SHAFT AND THE NO.4 CIRCULAR SHAFT. DEVELOPMENT WORK WAS DONE IN A PRE-EXISTING MINE BELIEVED TO BE EITHER THE OLD CONTINENTAL"A"OR HANOVER MINE. ORE IS TRAMMED 3500 FT ON THE 1300 LEVEL FROM THE NO.2 MINE TO THE NO.3 MINE SHAFT FOR HOISTING.

Comment (Deposit): MILS: OPEN PIT MINE & ASSOC. MILL EVALUATED BY R.C.SMITH UNDERGROUND MINE & ASSOC. MILL EVALUATED J.D.LEWIS SEE OPEN PIT ENTRY FOR CURRENT LEASE. MINE BEGAN PRODUCING ORE IN JUNE 1993. REF PROPERTY VISITED BY LEWIS & SMITH DURING OCT.,1977 FILE UPDATED & REVISED JUNE, 1978. COMMODITY GEOLOGIST BILL WORTHINGTON TOLD US THAT GOLD VALUE HAS BEEN REPORTED TO BE WORTH $1MILLION IN SMELTER CREDITS PER YEAR. PROSPECTUS,REF.3. ASSAY-NO CURRENT ASSAYS FOR AU AND AG WERE AVAILABLE.

Comment (Reserve-Resource): IS RECOVERABLE ORE. DOES NOT CONSIDER DILUTION. IS TOTAL ORE RESERVE PLUS 15% BARREN ROCK DILUTION. AN 87% RECOVERY IS CONSIDERED IN THE MINING SECTION, WHICH WILL REDUCE RESERVES AND MINE LIFE BY 13%. UNDERGROUND RESERVES ASSUMED AS MEASURED FROM 1976 ANNUAL REPORT. P25 = P50 X 1.10 P10 = P25 X 1.10, R2 = M2C3.

Comment (Production): PRODUCT GOLD AND SILVER RECOVERED FROM CONCENTRATE AT THE ASARCO SMELTER IN EL PASO, TEXAS. THE CONCENTRATE IS SMELTED ON A TOLL BASIS. CU CONCENTRATE AVERAGES 26 TO 27 PERCENT CU, 10-15 PERCENT ZN. THERE IS NO SIGNIFICANT ZN IN THE NEWER OPEN PIT AND ITS RESPECTIVE CONCENTRATE FLOAT. CONCENTRATE FLOAT.
