Comments on the geologic information

  • ADDITIONAL MINERALS NOT CODED FORTHIS MINE ARE HYDROZINCITE.
  • LABOR RECORD DATA BASE ON MINE AND RECOVERY PLANT AT FULL CAPACITY AND AT 240 OP DAYS/YR THE APEX ORE BODY IS AN IRREGULAR-SHAPED CHIMNEY-LIKE DEPOSIT CONTAINED WITHIN A SOLUTION COLLASPE BRECCIA THAT FORMED BY THE COLLASPE OF OVERLYING SEDIMENTARY ROCKS INTO SOLUTION CAVERNS WITHIN THE MISSISSIPIAN REDWALL LIMESTONE. THE GA & GE METALS ARE CONTAINED IN THE JAROSITE AND GOETHITE RESPECTIVELY. THE BRECCIA ZONE CONTAINS NUMEROUS OXIDE, SULFATE AND CARBONATE MINERALS FORMED BY OXIDATION AND SUPERGENE ENRICHMENT.

Comments on the reserve resource information

  • M1C1=R1. M2C1=R2. M3C1=R3. M9C4=M1C1. M9C5=M2C1. M9C6=M3C1. THIS QUANT MATRIX REPRESENTS ORE RESERVES BELOW THE 5434-FT LEVEL. THIS QUANT MATRIX REPRESENTS STOCKPILED DUMP ORE THAT IS BEING BLENDED WITH MINED ORE AT RECOVERY PLANT. THIS QUANT MATRIX REPRESENTS LOW-GRADE ORE RESERVES LOCATED ABOVE 5434-FT LEVEL. REPORTED IN 1986 ANN REPT AS IND. BUT MINE MGR STATED RESERVE AS ACTUALLY PROVEN. THIS RESERVE TOO LOW GRADE AND TOO DIFFICULT TO MINE AT PRESENT
