Comments on other economic factors

  • THE OWNER OF THE MINING PROPERTY IS BRUSH WELLMAN, INC., 1200 HANNA BUILDING, CLEVELAND, OHIO 44115 QUANT GRADE MATRIX BASED ON RESERVES GIVEN IN BRUSH WELLMAN 1991 ANNUAL REPORT, P. 29. THIS QUANT-GRADE MATRIX DEFINES THE 1992 STOCKPILED ORE M9C4=M1C1, M9C5=M2C1,M3C1=R2; COMBINED PROVEN AND PROBABLE RESERVES GIVEN IN BRUSH-WELLMAN 1992 ANN REPT, P. 20. THE WHOLE MINING OPERATION AT THE TOPAZ MT MINE CONSISTS OF VARIOUS PITS THAT CONTAIN AN AVERAGE OF 450,000 MTS OF ORE. EACH PIT IS INITIALLY DEVELOPED BY STRIPPING AN AVERAGE AMOUNT OF 7,645,000 CU-M OF OVERBURDEN IN A ONE YEAR PERIOD BY A CONTRACTOR. THE CONTRACTOR REMOVES THE OVERLYING RHYOLITE, AND A PORTION OF THE UNDERLYING TUFF, BY DRILLING AND AND BLASTING THE RHYOLITE, EXCAVATING THE BROKEN ROCK USING A FRONT-END LOADER, AND HAULING AND DRUMPING THE ROCK, AS BACKFILL, IN AN ADJACENT MINED-OUT PIT. APPROXIMATELY 2.1-M OF ALTERED TUFF IS LEFT OVERLYING THE ALTERED TUFF CONTAINING THE BERTRANDITE ORE, AFTER THIS INITIAL STRIPPING PHASE. THIS OVERLYING TUFF IS REMOVED DURING THE MINING PHASE. THIS WASTE AND ORE ARE MINED USING A SCRAPER AND DOZER. THE ORE IS TRANSPORTED BY THE SCRAPER LOCATED ADJACENT TO THE PIT TO EITHER A LOW-GRADE STOCKPILE (LESS THAN 0.65% BEO), OR A HIGH-GRADE STOCKPILE (GREATER THAN 0.65% BEO). THESE TWO STOCKPILES ALLOW THE ORE TO BE BLENDED BY THE TRUCKS TRANSPORTING THE ORE TO THE PROCESSING PLANT, LOCATED AT LYNNDYL, UT, (NEAR DELTA, UT). THE AVERAGE MINE LIFE FOR THESE PITS IS 5 YEARS. PRESENTLY (1992), THE ROADSIDE III AND SECTION 16 PITS ARE BEING MINED. IN 1994, STRIPPING WILL COMMENCE AT THE MONITOR PIT. THE ORE IS DILUTED BY 7% WHEN MINED
  • BERYLLIUM MINERAL IS BERTRANDITE. THE FEED GRADE IS A DILUTED BY 7% FROM THE IN-SITU ORE.
