Ore body information

  • General form IRREGULAR
    Strike N 60 E
    Dip NW
    Length 30.48M
    Width 15.24M

Controls for ore emplacement

  • The Main Productive Vein, Along A Contact Between Pioneer Formation And Diabase, Probably Represents An Old Fault Formed Before The Intrusion Of Diabase And Reopened By Slight Displacement After The Intrusion

Comments on the geologic information

  • THE BEST ORE WAS FORMED BY RESIDUAL CONCENTRATION AND DOWNWARD ENRICHMENT OF MANGANESE OXIDES AND DID NOT EXTEND BELOW A DEPTH OF ABOUT 20 FT FROM THE SURFACE

Workings at the site

  • Type of workings Surface/Underground
    Overall depth 2.44M
    Overall length 9.14M
    Overall width 2.44M

Comments on the workings information

  • SUPERIOR AND GLOBE PUT DOWN A 900 FT SHAFT WHILE EXPLORING FOR COPPER AND SILVER. THE MANGANESE ORE THAT WAS SHIPPED WAS SORTED FROM THE MATERIAL BROKEN IN AN OPEN CUT, 30X8X8 FT. SOME EXPLORATORY STRIPPING OF TALUS OVERBURDEN HAD BEEN DONE SOUTHWEST OF THE OPEN CUT

Comments on development

  • COPPER TRUST GROUP OF CLAIMS ORIGINALLY OWNED, ALONG WITH THE MAGNET AND KENO, BY THE SUPERIOR AND GLOBE COPPER MINING CO. WHO UNSUCCESSFULLY EXPLORED FOR COPPER UP TO 1910. IT WAS SOLD IN 1920'S OR 1930'S ALONG WITH THE MAGNET AND KENO TO F.A.BENNET, THEN RESOLD IN 1953 TO F.A. SITTON.
