without constructing a new road. In accordance with Rules 2.02.2(2)(f) and 4.21.4(3)(a), <br />vehicular travel on other than established graded and surfaced roads will be limited to that <br />absolutely necessary to conduct the exploration. Travel will be confined to graded and <br />surfaced roads during periods when excessive damage to vegetation or rutting of the land <br />surface could result from such travel. <br />Site Development — Drill Pad Construction: The selected drill -sites are located on gentle <br />slopes or bench areas to minimize grading requirements. Maximum drill pad dimensions <br />will be 100 x 100 feet (see Figure 2, General Drill Site Layout). However, based on <br />observations by CDRMS representatives in August 2008, in many instances, it may be <br />appropriate to only disturb the immediate area surrounding the proposed drill hole and the <br />accompanying mud pits. <br />Construction will be conducted in accordance with Rule 2.02.2(2)(f) and 4.21.4(5). Prior to <br />earth- moving or excavations of any type, the A and B horizons will be salvaged and stored in <br />an area that will be undisturbed and not subject to excessive wind or water erosion. At sites <br />that have been previously disturbed by agricultural or mining activities, if there is no <br />distinction between the A and B horizons, the topsoil will be salvaged as a single unit (letter <br />from CDRMS to Mr. Scott Cowman, dated October 6, 2008). The underlying subsoil <br />materials will, if necessary, be salvaged and stored in an area separate from A and B horizon <br />materials. After stripping and stockpiling the topsoil /subsoil materials, minor grading will be <br />completed to establish the drill pad and accommodate the drilling and support equipment. <br />Runoff and sediment contributions from the soil material stockpiles will be controlled <br />through placement of straw wattles or soil berms (approximately one foot in height) down <br />gradient from the stockpile(s). <br />Mud pits will be constructed within the graded pad area. Generally two or three pits are <br />required, with typical pit dimensions of 10 feet x 5 feet and 6 feet deep. The size of the <br />required pits is dependent on the anticipated drilling depths and conditions. Materials <br />excavated from the pits will be stockpiled on the margins of the pad area and used to backfill <br />the pits after the drilling is completed. All drilling fluids will be contained within the mud <br />pits, and all drilling supplies will be contained within the area of the drill pad. Any runoff <br />and associated suspended sediment from the drill pad will be controlled and contained by a <br />perimeter soil berm or silt fence on the down gradient side(s) of the drill pad. <br />Drilling Operations: A rotary drill -rig, capable of rotary drilling and spot- coring, will be <br />utilized for general exploration work. The drill -rig will be a truck - mounted, rubber -tired <br />unit, capable of operating in rough terrain. Support equipment will include, but not be <br />PSCM2012 NOI 14 April 2012 <br />
