Comment (Reserve-Resource): ANALYZED FOR COSTS BUT NOT INCLUDED IN AVAILABILITY CURVE FOR 1984 STUDY. AS OF 1988- PROPERTY IN DEVELOPMENT WITH EXPECT- ED STARTUP IN 1ST QTR.1989 AT 60,000 OZ.AU/YR LEVEL. 1989 PROD. WAS 39,500 OZ. FROM 880,000 MT ORE. 1989 RESERVE = 441,000 OZ.CONT.AU. PEFR SCHEDULED FOR DELIVERY MID-APRIL,1991. WILL BE INCLUDED IN 1992 AU AVAILABILITY STUDY. MINE SCHEDULED TO CLOSE LATE 1994.

Comment (Deposit): RECLAMATION OF THE MINE BEGAN 8-94, THE PROCESSING FACILITY WAS SOLD 1-95. THE RECLAMATION PROCESS WILL CONTINUE WITH THE THE MAJORITY OF SPENDING COMPLETED BY 1998.

Comment (Economic Factors): THERE IS PRESENTLY NO PROCESSING PLANT AND ONLY IF SUFFICIENT RESERVES ARE FOUND AND THE PROJECT IS ECONOMICALLY FEASIBLE WILL A MILL BE CONSTRUCTED. PRESENT PLANNING IS FOR A 1810 MT/DAY MILL TO BE COMPLETED IN LATE 1985 OR EARLY 1986. HISTORICALLY ORE FROM THIS SITE HAD AN APPROXIMATE GOLD-SILVER RATIO OF 4:1.

Comment (Reserve-Resource): IF A SHALLOW RESERVE OF AT LEAST 4,535,000 MT AT A GRADE OF 3.43 GM AU/MT OR BETTER IS FOUND IT IS ANTICIPATED THAT THE DEPOSIT WOULD BE EXPLOITED BY SURFACE MINING METHODS. IT IS ESTIMATED THAT MINE DILUTION WOULD BE AT LEAST 15 PERCENT, RESULTING IN A RECOVERABLE TONNAGE OF 5,215,000 MT AT A GRADE OF ABOUT 2.98 GM AU/MT.

Comment (Reserve-Resource): THE MINE SHUT DOWN IN JULY 1994 DUE TO THE DEPLETION OF THE ORE BODY.

Comment (Names): OTHER NAMES:LILLIAN;COLLAR&ELBOW LOAD

Comment (Workings): PROCESS CONSISTS OF FLOTATION AND CIL CIRCUIT. LOW-GRADE ORE IS STOCKPILED FOR FUTURE CONSIDERATION AND POSSIBLE HEAP LEACHING. AVERAGE GRADE OF ORE IS 0.06 OZ/T AU AND 0.10 OZ/T AG. THREE DISTINCT TYPES OF ORE EXIST.

Comment (Economic Factors): THE PLANNED CAPACITY OF THE ROYAL-MOUNTAIN KING PROJECT IS PRESENTLY 662,000 MT/YR.
