EXHIBIT 27, ITEM 1 <br />I. INTRODUCTION <br />The Collom Haul Road and Facilities Geotechnical Drilling Program, will also include areas <br />along the existing paved haul road, will consist of drilling 45 drill holes (please see Figure Exh. <br />27, Item 1) in order to obtain subsurface geological and geotechnical information for these areas. <br />When possible, bedrock samples will be collected and evaluated for rock quality, rock type, <br />weathering and hardness. Subsurface data in cut slope areas are necessary for use in evaluating <br />excavation conditions, cut slopes and the potential use as fill. <br />The areas to be drilled for Collom will be within the corridor to be disturbed by construction of <br />the Collom haul road and Collom facilities area. The data needed along the existing haul road <br />will support design criteria to relocate equipment from the South Taylor Pit to the Collom <br />operation. <br />Where possible, existing ranch roads will be utilized to access as close as possible to the drill <br />hole locations. Once equipment is close to the location, a small dozer will be used to brush an <br />access (approximately 15" wide) to allow the small track mounted drill rig to access each site. <br />Topsoil stripping will not be necessary for this activity. Should any geotechnical drill holes not <br />be disturbed by future disturbance areas, they will be in accordance with Volume 15, Table <br />2.05.9. <br />All borings will be logged by a geologist or geotechnical engineer and recorded on a field -boring <br />log. <br />II. DRILL HOLE SPECIFICS <br />Four drill holes (CHR -1 through CHR -4) are located adjacent to the Wilson Creek crossing <br />(please see Figure Exh. 27, Item 1). Drill hole depths will consist of 20 to 70 feet of penetration <br />into bedrock for culvert design input. <br />Two drill holes (CHR -5 and CHR -6) will be drilled to an approximate depth of 30 to 50 feet for <br />the culvert crossing at Jubb Creek for culvert design input (please see Figure Exh. 27, Item 1). <br />Ten drill holes (CHR -7 through CHR -15 and CHR -45), are located along the Collom haul road <br />corridor (please see Figure Exh. 27, Item 1). Drill hole depths will range from 15 feet to 70 feet <br />of penetration which is determined by the final grade of the haul road. <br />Exh. 27, Item 1-1 Revision Date: 5/20/16 <br />Revision No.: MR -150 <br />
