Comments on the workings information

  • 1962 CDM REPORT CITES 400-FT-DEEP SHAFT WITH LEVEL AT 200 FT. 1969 CDM REPORT CITES 220-FT-DEEP SHAFT WITH LEVELS AT 90 FT AND 200 FT. LATER REPORT CITES 200-FT-DEEP VERTICAL SHAFT WITH 4 LEVELS (LEVEL 1 AT 50 FT, LEVEL 3 AT 180 FT). NELSON AND RIESMEYER'S MAP SHOWS TWO SHAFTS.

Comments on development

  • EARLY HISTORY OF MINE IS UNKNOWN. AT LEAST ONE OF THE SHAFTS WAS SUNK IN 1900 BUT ABANDONED SHORTLY THEREATER, MINE WAS OPERATED IN 1920 BY ANACONDA MINING CO. BUT DID NOT PRODUCE ORE. MINE OPERATED IN 1950 BY HERBERT H. AND MARGARET C. LUCE BUT PRODUCED NO ORE. EXPLORATION CONDUCTED BY SMOKEY WARD MINING CO. IN 1962. EXPLORATION AND DEVELOPMENT FOR CU ORE WAS DONE IN 1969 BY SOVEREIGN RESOURCES. AT SOME TIME, ADJACENT PATENTED CLAIMS (INCLUDING HEADLIGHT MINE) WERE CONSOLIDATED INTO ANACONDA PROPERTY, HENCE THEIR INCLUSION AS PATENTED CLAIMS LISTED ABOVE (EXACT LOCATIONS OF UNPATENTED CLAIMS LISTED ARE UNKNOWN).

General comments

Subject category Comment text
Deposit NELSON AND RIESMEYER (1983) DESCRIBE DEPOSIT AS PYRITIC CHERT LAYER TRENDING GENERALLY N 63 W, WITH FOLIATION IN ENCLOSING BASALT TRENDING PARALLEL IN STRIKE AND DIPPING 75 TO 90 NE. LENTICULAR MASSIVE SULFIDE LENS OCCURS WITHIN SEQUENCE OF UNALTERED BASALT; CONTAINS ANGULAR TO ROUNDED FRAGMENTS, COBBLES, AND PEBBLES OF PYRITIC CHERT; AND DISPLAYS NO CHEMICAL ZONATION NOR LAYERING. LENS IS INTERPRETED TO REPRESENT DEPOSITION AS DEBRIS FLOW.
