Comments on the geologic information

  • GENERAL SIZE OF ORE BODY IS LARGE. THE PROJECT IS PRIMARILY LOCATED IN THE MILLTOWN ANDESITE PIT AREA GEOLOGY UNAVAILABLE, DATA DESCRIBES AREA OF DIST. AND THE OVERLYING DACITE, WHICH ARE MORE OR LESS CONCENTRI- CALLY SURROUNDED BY ASHFLOW TUFFS AND LACUSTRINE TUFFACEOUS BEDS. BOTH THE MILLTOWN AND OVERLYING DACITE ARE HIGHLY BLEACHED AND ALTERED. THE BLEACHED ROCKS HAVE BEEN ARGIL- LIZED, ALUNITIZED, AND SILICIFIED, AND BOTH ARE HOST FOR ORE DEPOSITS. THE ORE DEPOSITS ARE CLOSELY ALLIED TO FISSURE VEINS. STRUCTURALLY THE DEPOSITS ARE IRREGULAR MASSES OF ALTERED AND MINERALIZED ROCK TRAVERSED BY IRREGULAR INTER- SECTING FRACTURES, WITH THE FRACTURES PASSING INTO PLACES OF THOROUGH BECCIATION. TYPICALLY, THE ORE MASSES ARE CALLED LEDGES. WITHIN THE ZONE OF OXIDATION THE LEDGES ARE SILICIFIED INTO FRACTURED AND POROUS JASPERIOD. BELOW THIS ZONE, THE LEDGES BECOME LESS SILILEOUS AND LESS POROUS. THE MINERALIZED LEDGES RANGE FROM A FEW FEET TO HUNDREDS OF FEET IN LENGTH. THE ORE BODIES WITHIN THE LEDGES VARY IN SHAPE FROM PIPES TO EQUIDIMENSIONAL BODIES. THE DIPS VARY BUT ARE GENERALLY GREATER THAN 49 DEGREES TO THE EAST AND APPEAR TO ALIGN THEMSELVES DOWNDIP. THE OVERALL DIMENSIONS OF THE GOLD -FIELD ORE BODY IS ESTIMATED TO BE 30 METERS DEEP, 460 METERS IN LENGTH, AND NEARLY 45 METERS WIDE.

Comments on the reserve resource information

  • IN-SITU GEOLOGIC RESERVES ARE STATED TO BE 1.587,000 MT AT A GRADE OF 2.47 GM AU/MT. ASSUMING A 20 PERCENT DILUTION AT NEAR ZERO DILUTION GRADE AND TOTAL RESOURCE RECOVERY, THE OPEN PIT MINEABLE RECOVERABLE RESOURCE IS 1.904,000 MT AT A GRADE OF 2.06 GM GOLD/MT BASED UPON THE HISTORIC 3:1 GOLD: SILVER RATIO FOR THE DISTRICT, SILVER RECOVERABLE RESOURCE GRADES CAN BE EXPECTED TO BE ABOUT 0.69 GM SILVER/MT. IN ADDITIOON TO THE ABOVE UMNIMED RESOURCE, APPROXIMATELY 279,000 MT OF COMMERCIALLY EXPLOITABLE OLD DUMP MATERIAL EXISTS ON THE PROPERTY. THIS MATERIAL IS SAID TO HAVE A GRADE SIMILAR TO THE RECOVERABLE RESOURCE.
