Comments on the geologic information

  • TYPE OF WALLROCK ALTERATION IS MAINLY SERPENTINIZATION OF LIMESTONE. THE DEPTH TO MINERALIZATION FROM THE TOP OF THE HILL WITHIN WHICH THE OREBODY LIES IS ABOUT 235 METERS. ACCESS TO THE OREBODY, HOWEVER, IS BY AN ADIT DRIVEN INTO THE CANYON WALL JUST BELOW THE OREBODY. THE STRIKE AND DIP OF THE MINERALIZED ZONE VARY BECAUSE OF LOCAL FOLDING, BUT THE STRIKE IS GENERALLY NORTHWEST- SOUTHEAST WITH AN AVERAGE DIP OF 5 DEGREES NORTHEAST. THE OREBODY DIMENSIONS ARE APPROXIMATIONS GIVEN BY D.W. JAQUAYS. BECAUSE THESE DIMENSIONS ARE NOT EXACT, CALCULATIONS OF RESERVE TONNAGES BASED ON THESE DIMENSIONS ONLY APPROXIMATE THE Q-P75 RESERVE FIGURE. THE Q-P50, Q-P25, AND Q-P10 TONNAGES ARE NOT INCLUDED WITHIN THESE OREBODY DIMENSIONS.

Comments on the production information

  • PRODUCTION DATA SUPPLIED BY D.W. JAQUAYS. TONNAGES ROUNDED TO THE NEAREST METRIC TON. EXPLORATION HAS BEEN ALMOST NONEXISTENT EXCEPT FOR MINOR DRIFTING GENERALLY DONE WHEN ORE VEINS PINCHED OUT AT THE WORKING FACE. TEST RAISES HAVE OCCASIONALLY BEEN USED.
  • PA IS AAA GRADE FIBER (CASSIAR, B.C. CLASSIFICATION). PB, PC, AND PD ARE 3Z, 4T, AND 7MF GRADE FIBER, RESPECTIVELY (QUEBEC STANDARD CLASSIFICATION). ALTHOUGH GRADE AAA IS NOMINALLY EQUIVALENT TO QUEBEC STANDARD GROUP 3, THE MINE OWNER USES THE AAA GRADE TO DESIGNATE FIBER EQUIVALENT TO QUEBEC STANDARD GROUPS 1, 2, AND 3 CRUDES. THIS AAA FIBER IS GENERALLY 1 TO 2 INCHES (2.5 TO 5.1 CM) IN LENGTH AND IS A SPINNING GRADE. THIS AAA FIBER IS GENERALLY NOT FIBERIZED, THAT IS, IT IS NOT TREATED TO SEPARATE THE INDIVIDUAL FIBERS, BUT IS SOLD IN A CRUDE FORM. THE OTHER 3 PRODUCTS ARE FIBERIZED AND ARE USED IN A VARIETY OF APPLICATIONS. AT THE TIME OF THIS EVALUATION, THE DEPT. OF DEFENSE HAS A CRITICAL NEED FOR VERY LONG SPINNING FIBERS FOR USE IN A PROPOSED WEAPON SYSTEM. SINCE FIBERS UP TO ABOUT 9.5 CM IN LENGTH ARE KNOWN TO OCCUR IN THE EL DORADO DEPOSIT IN SMALL QUANTITIES, IT IS EXPECTED THAT FURTHER INVESTIGATION OF THE PROPERTY WILL BE FORTHCOMING. LONG FIBERS THAT ARE LOW IN IRON CONTENT ARE REQUIRED BY D.O.D. AND MIGHT POSSIBLY BE SUPPLIED BY THIS DEPOSIT. THIS COMBINATION OF ATTRIBUTES IS GEOLOGICALLY VERY RARE, AND THE ARIZONA DEPOSITS APPEAR TO BE THE ONLY POSSIBLE DOMESTIC SOURCE. THE MINE OWNER ESTIMATES THAT ALL AAA AND SOME OF THE 3Z FIBER RESERVES AT EL DORADO MIGHT MEET D.O.D. REQUIREMENTS.

MIN. RES. UNDER GRANT NO. GO254012. RECOVERABLE RESERVES ESTIMATED BY EVALUATOR TO BE 90% OF IN SITU RESERVES = 0.90 X 75600 MT = 68040 MT. OWNER STATES THAT THERE IS NO DILUTION. ALL TONNAGES SHOWN IN MATRICES 1 AND 9 ARE ROUNDED TO THE NEAREST 1000 MT.

Comments on other economic factors

  • THE LATITUDE AND LONGITUDE OF THE MILL ARE APPROXIMATE. THE DESIGN CAPACITY OF THE MILL IS BASED ON A ONE-SHIFT-PER- DAY OPERATION. THE MILLING PROCESS CONSISTS OF RELEASING THE FIBERS FROM THE ROCK THROUGH REPEATED SUCCESSIVE STAGES OF CRUSHING, SCREENING, FIBERIZING, AND AIR CLASSIFYING. MOST OF THE CRUDES (AAA GRADE) ARE EXTRACTED BEFORE FIBERIZING THROUGH REPEATED STAGES OF CRUSHING, SCREENING, AND AIR CLASSIFYING. THE REMAINING CRUDES ARE REMOVED FOLLOWING THE FIRST STAGE OF FIBERIZING. THE REMAINING 3Z, 4T, AND 7MF GRADES ARE REMOVED THROUGH FURTHER REPEATED STAGES OF FIBERIZING, SCREENING, AND AIR CLASSIFYING. THE INVESTMENT FIGURE REPRESENTS WORKING CAPITAL AND THE COST OF INSTALLING DUST CONTROL EQUIPMENT IN 1970. ALL OTHER CAP. COSTS RELATED TO THE MILL ARE DEPRECIATED.
