Comments on the geologic information

  • Lying wholly within the fragmental and intrusive rocks of the Cripple Creek volcanic complex, the mine is characterized by a pipe-like basaltic breccia mass known as the Cresson blowout. Ore occurs as broad zones of low-grade disseminated native gold with pyrite and potassium alteration, with hydrous iron and manganese oxides, or as gold-silver tellurides in narrow quartz-fluorite fractures.

Comments on the production information

  • Production began in 1995, and more than 2.6 million oz. of gold had been produced by the end of 2005.
  • PRODUCT RECORD A REFERS TO THE VICTOR PLANT THAT IS CURRENTLY OPERATING. PRODUCT RECORD B REFERS TO THE FUTURE RECOVERY PLANT FOR THE CRESSON DEPOSIT.
  • THE RECOVERY GIVEN IS AN AVERAGE. RECOVERIES RANGE FROM 50 TO 80%. SILVER IS RECOVERED AT ABOUT THE SAME RATE AS GOLD, BUT THE RECOVERY FOR SILVER IS NOT GENERALLY DETERMINED. THEREFORE THE SAME RECOVERY HAS BEEN ASSUMED FOR SILVER. THE DORE GRADES ARE ESTIMATES BUT VARY CONSIDERABLY. DORE GRADES RANGE FROM 60 TO 75% AU AND 25 TO 40% AG.

Comments on the reserve resource information

  • At the end of 2005, ore reserves were 119,100,000 metric tonnes containing 102.7 metric tonnes of gold (131,300,000 tons containing 3,300,000 tr. oz. of gold) at an average grade of 0.85 grams/metric tonne (0.029 tr. oz./ton).
  • At the end of 2004, ore reserves were estimated at 134,299,000 tons containing 3,877,815 tr. oz. of gold ( 2,374,467 tr. oz. recoverable) at an average grade of 0.029 tr. oz./ton.

Comments on other economic factors

  • DORE IS MAILED TO JOHNSON & MATHEY IN SALT LAKE CITY, UTAH.
  • THE GRADE GIVEN FOR SILVER IS AN ESTIMATE BASED ON 1992 PRODUCTION. SILVER IS NOT ASSAYED OR RECOVERY DETERMINED. THE GRADE GIVEN IS CONSISTENT WITH THE HISTORICAL AVERAGE.

Comments on development

  • The Cripple Creek & Victor Gold Mining Co. joint venture began design of the project in 1992 and commenced production in 1995. Expansion of operations has resulted in a surface mine (2006) moving 20 million tons of ore/yr., using shovels, loaders, and trucks, and a valley-heap cyanide-leach process to recover gold from ore grading about 1 g/ton.
