URAVAN-BECK PROJECT DRILL SITE P-2 Page 4 of 6 <br />NOTICE OF INTENT TO COMMENCE PROSPECTING <br />APPENDICES To NOI APPLICATION <br />NRCS data from Soil Survey C0675 - Parts of Montrose, Dolores, and San Miguel <br />Counties, 2008 lists the drill site as being in the Gladel-Bond-Rock outcrop complex (Map <br />Unit 45), 1 to 50 percent slopes. The NRCS data does not list any plant species for this map <br />unit, although vegetative production (dry weight) is estimated to be 50-300 pounds per acre <br />for Gladel soils and 200-600 pounds per acre for Bond soils. <br />Section IV. 3. <br />Soil depth ranges from 0-8 inches on the Gladel soils (sandy loam), and 0 to 16 inches on <br />the Bond soils (fine sandy loam to clay loam). Below the soil material is unweathered <br />bedrock derived from sandstone residuum. <br />Soil will be stripped to a 6 in. depth from a 20 ft. diameter area around each drill hole. Total <br />volume of topsoil stored per drill hole will be approximately 7.4 CY. Soil will be stored in one <br />pile for each drill fence, close to the drill holes. <br />Upon reclamation, any cuttings that do not fit back in the hole will be spread in an area up to <br />20 ft. in diameter around each drill hole with the backhoe. Topsoil will then be re-spread to <br />an average depth of 6 inches over the 20-ft. diameter area around each drill hole using the <br />backhoe. <br />Section IV. 4. <br />After geophysical logging, all holes will be backfilled with cuttings, concrete-plugged at 7 to <br />2 ft. below ground surface (bgs), and dirt-filled from 2 to 0 ft. bgs to meet Colorado <br />abandonment regulations as described in Chapter 5.4 of the DRMS hard rock regulations. <br />Any drill holes that have evidence of artesian flow will be plugged with a neat cement grout <br />or similar material to prevent any flow to the surface. Any hole that encounters an aquifer <br />will be sealed to prevent contamination of this aquifer using high quality sodium bentonite <br />gel specifically designed for use as an abandonment fluid. All dry holes will be backfilled <br />with cuttings, and plugged from 7 to 2 ft. bgs with a cement plug. The final two ft. to the <br />surface will be filled with remaining cuttings or dirt.
