Comments on the reserve resource information

  • ADDITIONAL RESERVES OF 10-15 MILLION ST OF SIMILAR GRADE RESERVES ARE POSSIBLE.

Comments on the workings information

  • UNDERGROUND OPERATION IN 1941. LATER DEVELOPMENT FOR HEAP LEACH.

Comments on development

  • PREVIOUS OPERATORS INCLUDED: WILLIAM THOMPSON, C.O. HEWINS. THE VAN DEEMEN MINE EXPLORATION DRILLING TOTALED 13 REVERSE CIRCULATION HOLES FOR A TOTAL OF 5000 FT. AMSELCO EXPLORATION USED GEOLOGIC MAPPING AND INTERPRETATION TO DETERMINE THAT THE MINERALIZED ZONE WAS A LOW-ANGLE BRECCIA. VAN DEEMEN HAS BEEN SUBLEASED TO FRISCO MINING FOR AN AIRTRACK DRILLING PROGRAM AND ARIZONA STAR RESOURCE HAS CONDUCTED SURFACE DRILLING OVER 4 DETACHMENT BRECCIA TARGETS (FALL, 1986) WITH FURTHER DRILLING TO BE DONE IN 1987. IN 1987, ARIZONA STAR RESOURCE CO. STARTED DEVELOPING THE EXTENSIVE HEAP-LEACH GOLD RESERVES.
