AmerAlia, Inc. <br />LITHOLOGY <br />AM2 Drilling and Completion Report <br />Table 2 details the lithologic chazacteristics of the drill hole cuttings from AM2. The colluvium <br />and alluvium from the surface to 82 feet consists of sand and gravel composed mainly of light- <br />brown, fine- to medium-grained sandstone (20 to 90 percent of the cuttings) and light-brown, <br />fine-grained siltstone (10 to 80 percent of the cuttings). Cuttings from the Uinta Formation <br />(82 to 90 feet) consisted entirely oflight-brown, very fine- to medium-grained sandstone. <br />GROUNDWATER HYDROLOGY <br />After noting damp cuttings at a depth of about 37 feet, the first groundwater dischazge occurred <br />at approximately 48 feet (Table 1). Discharge was estimated at 20 gallons per minute (gpm). <br />Geochemical analyses (discharge flow rate, pH, temperature, conductivity, and total dissolved <br />solids [TDS]) of dischazge water from drill depths of 48, 70, and 80 feet were conducted on site; <br />results are provided in Table 3. Temperature values ranged from 9.0 °C to 12.0 °C, with an <br />average of 10.6 °C, and pH values ranged from 7.95 to 8.06, with an average of 8.00. <br />Conductivity values ranged from 780 to 1,160 microsiemens per centimeter (µS/cm), with an <br />average of 917 µS/cm, and TDS values ranged from 200 to 400 parts-per-million (ppm), with an <br />average of 300 ppm. <br />One static water-level measurement was taken on January 29, 2000, shortly after the unconfined <br />water table was penetrated at 48 feet. The depth to the water table was measured at 31.56 feet <br />below ground level. <br />Daub & Associates, Inc. <br />
