6 <br />gamma and neutron density in order to delineate the ore body. <br />Resistivity logs were also run if ground water was encountered. <br />The geophysical logs from these numerous test holes were reviewed <br />to determine where and at what depth ground water was present. <br />Sufficient datra was available from 224 of the holes for use in our <br />study. Ground water levels were measured during this investigation in <br />twelve accessible holes by lowering an electrical sensing probe down <br />the hole until the ground water level was contacted and an electrical <br />circuit was completed, producing a reading on the instrument's gauge. <br />Based on the long term water levels measured in these selected holes, <br />we concluded that ground water levels were not significantly affected <br />by the drilling operation and that the levels measured at the tine of <br />drilling were an accurate representation of the static ground water <br />conditions. <br />REGIONAL GEOLOGY <br />The JD-5 uranium lease is located about 12 miles west of <br />Naturita, Colorado as shown on Fig. 1. The lease is located on the <br />southwestern side of the Paradox Valley. The valley has resulted from <br />collapse and erosion along the crest of a northwest trending <br />salt -cored anticline. The Paradox Valley anticline and adjacent <br />northwest trending salt anticlines are located in the Canyon Lands <br />section of the Colorado Plateau physiographic province, Fenneman <br />(1931). This section of the Colorado Plateau is characterized by <br />flat -lying to gently dipping sedimentary rocks which have deeply <br />incised canyons cut by the Colorado River and its principal <br />
