Ore body information

  • General form PODS
    Strike N 35 E
    Dip 45 NW
    Length 30.48M
    Width 1.83M

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 FEET FROM THE SURFACE

Comments on the workings information

  • WORKINGS CONSIST OF ADIT AND INCLINED SHAFT, AND A FEW SHALLOW CUTS

Comments on development

  • KENO, A FRACTIONAL CLAIM, ORIGINALLY BELONGED TO THE SUPERIOR AND GLOBE MINING CO., ALONG WITH THE COPPER TRUST AND MAGNET GROUPS. IT ADJOINS THE NORTHEAST END OF THE MAGNET GROUP. THE KENO, ALONG WITH THE COPPER TRUST AND MAGNET, WAS SOLD IN THE 1920'S OR 1930'S TO F.A. BENNET AND THEN IN 1953 TO F.A.SITTON. CLAIM WAS FIRST MINED IN 1940'S BUT DID NOT SHIP UNTIL 1953
