6.4.5 Exhibit E Reclamation Plan The reclamation plan for the Headley Mine, permit number M- 1980 -135 owned by Pinneo Feedlot, LLC has been developed in accordance to the requirements of 6.3.4 Exhibit "E" Reclamation Plan in the Mineral Rules and Regulations of the Colorado Mined Land Reclamation Board for the Extraction of Construction Materials, August 2006. A complete document search of the Colorado Division of Reclamation, Mining and Safety web link was completed and a written reclamation plan was not found with the original documents. This reclamation plan is to supplement the original Exhibit "F" Reclamation Plan and prepared in accordance to Construction Materials Rule 3. The mining permit was transferred to Pinneo Feedlot, LLC in an approved Succession of Operators from Western Cleanup Corporation in April 2004. The site contains four gravel pits. The site has not been mined since the permit was transferred in 2004 and no mining will occur in the future. Rule 3.1.3 states that all reclamation must be completed within five (5) years from the date that mining ceases. Reclamation will commence upon approval of this plan. Final Grading Final grading will be such that the topography is appropriate to the reclaimed use of the property, i.e. rangeland. As required the maximum gradient will not exceed 2:1. As required by Rule 6.4.5(2)(a), earthmoving will be simple and typical of this type of material. The use of a back hoe and bulldozer will be used to reduce the vertical walls to a final grade of 2H:1 V. The overburden and waste material shall be replaced according to Best Management Practices (BMP) to ensure adequate compaction when backfilling. The concrete rubble pile is located approximately 400 feet north of Pit No. 2. The approximate volume of the inert concrete material to be back filled in Pit No. 2 is 1067 cubic yards. The concrete rubble will be placed in Pit No. 2 from the edge of the exposed water in alternating layers with concrete and dirt, the water will allow for settlement of the fine material over the large rubble. Pit No. 2 will be backfilled to a depth of two feet above water level. The proposed reclamation activity will commence in March 2011 and end in September 2011, weather permitting. The backfilled site will result in a re- vegetated land area compatible with the proposed post- mining use of rangeland for cattle grazing. Pit No. 3 reclamation is complete. The pit and groundwater pond support the post- mining land use as a recharge pond, currently known as Headley Recharge Pond 2, for an existing augmentation plan operated by the Owner. The original Reclamation Plan Map shows that Pit No. 1 and Pit No. 2 will be reclaimed into a single pit; however, these pits will be reclaimed as separate pits due to the extent of mining completed prior to the mine closure.
