(BLM ~ COC-076-96-N-01). <br />The Liberty Claims prospect, originally approved for eight (8) <br />surface drill holes was completed (drilling and reclamation) on <br />7/8/96. Physical drilling was completed on 6/5/96. <br />Holes Drilled <br />Of the eight (8) holes approved for drilling, one hole (reference <br />#1) was not drilled thereby reducing the total holes drilled to <br />seven (7). <br />Water Encountered <br />Of the holes drilled, one (1} reference #3 (JB-96-1) encountered <br />water in the Burro Canyon (Kbc) formation with the remainder of <br />holes encountering water in the Brushy Basin Mbr. of the Morrison <br />Formation (Jmb). Because the holes were not cased during <br />drilling, occurrences of ground water beneath the initial <br />intercept could not be determined and water samples taken from <br />the Salt Wash ore horizon will reflect a co-mingling of water <br />possibly produced from that horizon and those occurrences from <br />higher in the geologic column. <br />Hole Abandonment <br />All of the holes were abandoned utilizing 'cuttings to backfill <br />the non water bearing horizons and sodium bentonite pellets to <br />' seal the actual or suspected aquifers in the Saltwash and Brushy <br />Basin Members of the Morrison Formation. One bag of sodium <br />bentonite pellets or its equivalent in cuttings was utilized for <br />five vertical feet of drill hole. <br />
