EXHIBIT 27, ITEM 1 <br />I. INTRODUCTION <br />The Collom Haul Road and Facilities Geotechnical Drilling Program will consist of drilling 28 <br />drill holes (please see Figure Exh. 27, Item 1) in order obtain data for the Collom facilities haul <br />road design and construction. The area to be drilled occurs in the corridor to be disturbed by <br />construction of the access/haul road and Collom facilities area. Where possible, existing ranch <br />roads will be utilized to access as close as possible to the drill hole locations. Once equipment is <br />close to the drill hole locations a small dozer will be used to brush an access (approximately 15" <br />wide) to allow the small track mounted drill rig to access each location. Topsoil stripping will <br />not be necessary for this activity. Should any geotechnical drill hole and access road not be <br />disturbed during development of the Collom Mine those disturbance areas will be in accordance <br />with Volume 15, Table 2.05.9. <br />Four drill holes (CHR -1 through CHR -4) will be drilled adjacent to the Wilson Creek crossing <br />(please see Figure Exh. 27, Item 1). Borings will be advanced to obtain subsurface geological <br />and geotechnical information at these locations at hole depths of at least 70 feet or 20 feet <br />penetration into bedrock. When possible, bedrock samples will be collected and evaluated for <br />rock quality, rock type, weathering and hardness. <br />Two drill holes (CHR -5 and CHR -6) will be drilled using solid stem auger and air -coring <br />methods as appropriate to approximate depths of 30 to 50 feet for the culvert crossing at Jubb <br />Creek for culvert design input (please see Figure Exh. 27, Item 1). <br />Nine drill holes (CHR -7 through CHR -15), located along the Collom Access Road corridor <br />(please see Figure Exh. 27, Item 1), will be drilled using solid stem auger and air -coring methods <br />as appropriate. Borings will be advanced to obtain subsurface geological and geotechnical <br />information at these locations. Subsurface data in cut slope areas are necessary for use in <br />evaluating excavation conditions, cut slopes and the potential use as fill. <br />Eight drill holes (CHR -16 through CHR -23) will be drilled between Little Collom Gulch and the <br />West Fork of Jubb Creek (please see Figure Exh. 27, Item 1). Borings will be advanced to <br />obtain subsurface geological and geotechnical information at these locations. Hole depths will <br />range from 15 feet to 70 feet penetration which is determined by the final grade of the facilities. <br />When possible, bedrock samples will be collected and evaluated for rock quality, rock type, <br />weathering and hardness. <br />Exh. 27, Item 1-1 Revision Date: 01/04/16 <br />Revision No.: MR -150 <br />
