Comments on the geologic information

  • THE URANIUM MINERALS ARE PRESENT IN A ALTERED AND SILICIFIED FRACTURE ZONE IN CRETACEOUS QUARTZ MONZONITE. A MOLYBENUM PROSPECT IS NEAR BY. THE SOURCE OF THE URANIUM MINERALIZATION COULD HAVE BEEN THE OVER LYING ASH FLOW TUFFS IN THE URANIUM BEING CONCENTRATED IN THE FRACTURE ZONE BY CIRCULATING GROUND WATER. (PERSONAL CONJECTURE)
