Ore body information

  • General form LENTICULAR BODIES
    Strike N 45 E
    Dip 65 NW
    Length 822.96M
    Width 3.66M
    Depth to top 0M
    Depth to bottom 30.48M

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
