Comments on development

  • THE BUNCE PROPERTY WAS DISCOVERED IN THE 1930'S, BUT REMAINED UNDEVELOPED UNTIL THE ADVENT OF HEAP LEACH TECHNOLOGY. IN 1984, HILLSIDE ENERGY LEASED 80 ACRES OF PRIVATE LAND FROM THE BUNCE ESTATE AND JOINT VENTURED IT WITH NORAMEX MINERALS. ADDITIONAL LAND WAS ACQUIRED BY STAKING. ALSO IN 1984, TRENCHING EXPOSED GOLD MINERALIZATION OVER WIDTHS OF 30 AND 25 M, OPEN ON BOTH ENDS, IN 2 TRENCHES 120 M APART. IN APRIL 1987, CALVADA RESOURCES OPTIONED THE PROPERTY AND DRILLED 4970 FT. BEFORE DROPPING THE OPTION. IN LATE 1988, NORAMEX INCREASED ITS INTEREST FROM 56% TO 100% BY BUYING OUT THE HILLSIDE INTEREST. IN 1989, NORAMEX FINALIZED AGREEMENT WITH SANTA FE PACIFIC MINERALS INC. TO UNITIZE THE RESPECTIVE MINERAL LANDS IN THE AREA. IN MAY 1990, NORAMEX GRANTED ANNABEL GOLD MINES INC. THE RIGHT TO EARN 44% RELATIVE TO NORAMEX BY INCURRING $800,000 IN EXPLORATION EXPENDITURES. PRIOR TO THE SANTA FE AGREEMENT, 6420 FT. HAD BEEN DRILLED ON THE BUNCE LEASE PLUS 1600 FT. BY SANTA FE ON ITS
  • ADJOINING GROUND. THE BEST DRILL INTERCEPT WAS 70 FT./0.107 OPT AU. A 6090 FT. DRILLING PROGRAM WAS COMPLETED ON THE SANTA FE AND BUNCE LEASE GROUND IN 1990. A 15,000 FT. REVERSE CIRCULATION DRILLING PROGRAM WAS SCHEDULED FOR COMPLETION BY MID-1991, FOLLOWED BY METALLURGICAL AND FEASIBILITY STUDIES.

General comments

Subject category Comment text
Deposit THE GOLD OCCURS AS FINE PARTICLES DISSEMINATED IN RHYOLITE. EMPLACEMENT APPEARS TO BE RELATED TO SILICIFICATION AND HYDROTHERMAL ALTERATION IN A NEAR-SURFACE ENVIRONMENT CHARACTERIZED BY HYDROTHERMAL EXPLOSION BRECCIAS AND EXTENSIVE FOSSIL HOT SPRING SINTERS.; MODEL NAME COULD ALSO BE: HOT-SPRING AU-AG.
