EXHIBIT D MINING PLAN AND TIMETABLE LOCATION This is an open pit mine located approximately 11 . 6 miles northwest of Walsenburg, Colorado on County Road 615 . From I-25 north of Walsenburg, Exit I-25 at Exit 56 - Red Rock Road, west 2 . 5 miles to SHWY 69 . Then northwest on SHWY 69 for 7 . 95 miles to CR 614 . 1 (intersection coordinates 37d43 ' 16 . 28" , 104d58 ' 36 . 41" ) . Then northeast 0 . 6 mile on CR 614 . 1 to CR 615 running east-west, then east about 0 . 5 mile to cattle guard & gate . The entrance to the mine is at 37d43147 . 1711 , 104d5812 . 83 " . Mining access will be via this existing road that is a owned by the landowner to access his property from CR 614 . 1 . It is currently 20 feet wide and the location is shown on the map exhibits supplied with this applica- tion. Periodic grading will be necessary to keep the road in its present condition. It will remain after mining is complete for landowner access . Please refer to EXHIBIT B -VICINITY MAP for the property configuration and the relationships to surrounding geological features . CURRENT CONDITIONS MapExhibitC shows the outline of the Affected Lands; the touching landowners; the 200 foot ownership; structures; current topography, and hydrologic features of the property. Surrounding property uses include rangeland on all sides . The land along the south side is used by the property owners as undeveloped open lands and to the north across the Huerfano River the property owners have irrigated grasslands . The Perrino' s have a ranch yard and house on the northwest side of the permit area and own a school house on the access road east of the house area. At this time both structures will remain so we plan to establish a mining setback of 200 feet from the main structures in those areas . Along the north side of the terrace is a near vertical face that exists along the transition area from the rangeland down to the river bottom. The area north of that is river bottom land. This face appears to have been created by past flood events on the Huerfano River. It is marked by erosion channels where water has run off the rangeland into the river bottom. The site is currently used as rangeland and consists of a gravel terrace paralleling the southern side of the Huerfano River valley. The usable materials on this site ranges from 5 to 50+ feet deep . 6
