Mining Plan <br />EXHIBIT D <br />General <br />This is an application for a 112 Reclamation Permit for the Iverson Mine. The Iverson Mine is <br />located in Section 34, Township 6 North, Range 66 West of the 6 PM and includes a total of 66.5 <br />acres. The site is north of F Street and directly south of the Cache La Poudre River. The property <br />contains a significant commercial deposit of sand and gravel from the River. <br />Within the 66.5 acre permit boundary, 65.9 acres of land could potentially be disturbed; the only <br />permitted area that won't be disturbed from its current state is the access driveway into the property. <br />Within the 65.9 acres that could potentially be disturbed, only 39.8 acres of the property will be <br />mined. Other unmined acreage that may be disturbed will be used for overburden and topsoil <br />stockpiles, offsets from existing structures, internal roads, and conveyors. All of the mining <br />activities will occur on land owned by Tim and Jeanne Iverson. A strip of land owned by the City <br />of Greeley is also included in the permit boundary and will be disturbed; it will be used for a <br />conveyor that will carry material from the Iverson Mine to the 35 Avenue Mine (M- 1977 -036) for <br />processing. <br />Existing mining activities are occurring northeast of the Iverson Mine by Lafarge (35 Avenue <br />Mine) and a quarter of a mile east by Aggregate Industries. Otherwise, riparian vegetation and <br />agricultural uses surround the property. <br />The site was drilled in December 2003 and again in December 2008 and testing was performed to <br />verify the sand and gravel deposits are commercially marketable. The topsoil is approximately six <br />to twelve inches deep and there is three to six feet of overburden across the site. Based on this, it is <br />estimated that the topsoil will amount to approximately 40,000 cubic yards and overburden will <br />amount to approximately 230,200 cubic yards. All overburden needed for the construction of the <br />final reclamation slopes will remain on -site. The sand and gravel is 14' -29' deep across the site and <br />mining at the site is intended to progress down to claystone or sandstone. It is estimated that there <br />are approximately 1,500,000 tons of sand and gravel to be mined from the site. <br />The groundwater level lies approximately 5 to 10 feet below natural ground level, on average. The <br />deposit is therefore classified as a wet alluvial deposit. However, mining operations will be carried <br />out following dewatering. <br />As described above, the site is owned by Timothy and Jeanne Iverson and the City of Greeley. <br />Lafarge has a lease to mine the Iverson property and a conveyor access agreement with the City of <br />Greeley on their property. <br />Methods of Mining <br />The typical mining procedure will be as follows. Any areas slated for protection will be identified <br />in the field to assure that mining operations will be set back as appropriate. When mining begins, <br />the southeast corner of the mine cell will be stripped and the topsoil and overburden will be <br />Iverson Mine <br />DRMS 112 Reclamation Permit Application <br />Page D1 of D4 <br />
