EXHIBIT D <br />MINE PLAN <br />The Loloff Pit is an operational sand and gravel mine, with this application being for the expansion of the <br />existing reclamation boundaries to include 4.24 acres of additional mining area. The site is <br />approximately 55.17 acres with 42.7 acres of impacted area currently permitted under Permit M-1985- <br />112 on file with the Colorado Division of Reclamation Mining & Safety. The permit area of 55.17 acres <br />shall remain unchanged, however, the mine and reclamation limits are proposed to be increased with <br />this amendment. <br />Exhibit C shows the current permitted mining area and Exhibit D shows the proposed areas to be <br />affected under the amendment to the reclamation permit. The affected areas include Area 1 in the <br />northeast corner of the property that was identified as a shop and storage area in the original permit <br />application. The property ownership changed hands over the two years and it is the new owners desire <br />to mine this area as it contains approximately 450,000 tons of material with an average depth of 45 feet <br />in the northeast corner. The other area where the modified mine boundaries are being requested is in <br />the south west corner of the property identified on the map as Area 2. This area was disturbed by <br />previous operators and this amendment includes this disturbance. This amendment shall accommodate <br />the minimum offsets while maximizing the water storage volume for post reclamation use. This area is <br />not a mining area as much as it is an amendment to the reclamation plan. The modifications proposed <br />in Area 2 do not create any additional encroachment of existing structures. This area of impact is <br />approximately 0.25 acres and there is not any significant depth of material. <br />The current method of mining is a dry mining operation with de -watering occurring in the southeast <br />corner of the property. De -watering trenches have been excavated and the sand and gravel is <br />subsequently mined using an excavator to load haul trucks to haul material to a stockpile to feed the <br />crusher plant. The crusher plant is loaded with front end loaders and the final product of road base will <br />be loaded into trucks with front end loaders from a stockpile. The pit is currently mined in areas of 15- <br />20 acres at a time with 5-10 feet of depth of material. Stability analysis were performed with the Loloff <br />Pit Permit M-1985-112 Technical Revision No. 1 and revised with this amendment to include the slurry <br />wall. All mining techniques submitted with TR -01 will apply to the amended areas to be mined. The <br />results of the stability analysis have been attached for your review. There is no use of explosives on this <br />site and there are no explosives to be stored on site. <br />The material being mined currently is sand and gravel that is crushed and screened to create various <br />road base products or it is sold as pit run and used for construction materials. These construction <br />materials are being utilized in the oil and gas fields for pad site construction and with the current market <br />in new site development, the intended timeline for the completion of the reclamation of the pit is <br />2017/2018, but is subject to change as the market changes. It should be noted that the slopes are being
