Whirlwind Mine Groundwater Characterization Report <br /> seepage points maintained a thin film of free water on the rock surfaces that resulted in drips in <br /> places, but no distinct running rills were observed. <br /> 4.2.1.3 Cotter Exploration Drill Holes <br /> Cotter conducted an exploratory drilling project on their Liberty Claims prospect in the summer <br /> of 1996. The Liberty claims are located between the west-trending drift at the bottom of the <br /> Whirlwind Decline, and the western-most workings of the Packrat Mine, on top of the mesa just <br /> west of the Whirlwind Decline portal (see Figure 2). This area is also the same general location <br /> of Borehole BM00-1 (Lots 3 and 4, Section 35, T. 51 N., R.20W., N.M.P.M.). Of the seven holes <br /> drilled, one (JB-96-1) encountered groundwater in the Burro Canyon. The other six holes <br /> encountered groundwater in the Brushy Basin. Recognition of this groundwater was based on <br /> the depth the water was first encountered. This is because exploration holes were not cased <br /> and groundwater encountered at deeper depths frequently cannot easily be distinguished from <br /> the initial shallow groundwater. Groundwater encountered at deeper depths will commingle with <br /> the shallower groundwater. The results of the drill hole groundwater observations are <br /> summarized in Table 1 (Cotter, 1996). <br /> Cotter collected one groundwater sample from drill hole JB-96-2. These data are discussed in <br /> Section 5.0 (Water Chemistry) of this report. <br /> 4.2.1.4 Umetco Test Hole BM00-1 <br /> In September of 2000, Umetco drilled Boring BM00-1 to a depth of 560 ft to investigate <br /> groundwater occurrence and quality in the Burro Canyon Formation and the Brushy Basin and <br /> Salt Wash Members of the Morrison Formation (see Figure 2). The boring location was located <br /> on Beaver Mesa near the Utah state line (SW1/4 Section 35, Township 51 North, Range 20 <br /> West, 6th Principal Meridian). This location was selected because of reports of groundwater in a <br /> Cotter exploration hole JB-96-2, located 10 ft. to the north of BM00-1. In particular, the <br /> background radiologic parameters of the Salt Wash groundwater were of interest in the <br /> investigation. Umetco's report of this investigation is included in Appendix C of both the DRMS <br /> mine permit and BLM plan of operation. <br /> Western Water S Land, Inc. 17 <br />
