Economic information

Geologic structures

Type of structure Regional
Structure description Thirty Nine Mile Volcanic Field, Currant Creek Basin
Type of structure Local
Structure description Echo Park Graben, Paleovalleys, Faults; Reverse Fault Strikes N18w, Dips 35ne

Ore body information

  • General form TABULAR, PODS, LENS-SHAPED
    Thickness 12.19M
    Depth to top 27.43M

Controls for ore emplacement

  • Deposition Controlled By Ground Water Flow Conditions And Carbonaceous Material With Associated Pyrite. Flow Was Impeded By The Fault On The Southern End Of The Echo Park Graben. Highest Grade Ore Near A Fault. Meanders May Have Helped To Localize Ore

Comments on the geologic information

  • DEPOSITS LOCALIZED AND PRESERVED BY SLUGGISH GROUNDWATER MOVEMENT IN AREA. THOSE CONDITIONS STILL PRESENT AS EVIDENCED BY ARTESIAN PRESSURE IN WELLS AND SPRINGS ISSUING FROM ECHO PARK FORMATION AND BY A PRESENT URANIUM CONTENT OF GROUNDWATER IN AREA AS HIGH AS 900 PPB.
