Comments on the analytical data

  • 1 channel, 5 chip samples [RME-1061, p. 11]:
    channel 0.10% U3O8, 0.28% V2O5,
    2 chip samples: 0.07% U3O8, 0.15% V2O5 and 0.29% U3O8, 0.32% V2O5.
    2 chip samples yielded just "trace" of both U and V, one chip sample had none of each.

General Moved coordinates from SW4 of Sec. 19 to C of E edge to mines shown but not labeled on topo.
Deposit UP TO .29% U OXIDE and 0.32% V2O5.
Deposit "This depoist is low in the Fall River formation and on the west flank of a small anticline. The host rock is a massive, gray-to-buff, fine-grained, limonite-stained sandstone containing abundant carbon. Carnotite type minerals are found as interstitial fillings and as coatings on sand grains. High radioactivity is found across a 6-foot thickness and extends for approximately 75 feet along the outcrop." [RME-1061, p. 9] "Another area of high radioactivity, several hundred feet southeast of this deposit, shows sparse uranium mineralization in a 2-foot thick sandstone bed of the Fall River formation" [RME-1061, p. 11].
