6.4.4 Exhibit D <br />Mining Plan <br />The ]&] Stone Pit #1 target sandstone deposit lies within the Travesilla-Rock <br />outcrop complex. The primary and only commodity is landscape sandstone. The Soil <br />Conservation Survey report states little to no topsoil, overburden or vegetation is <br />present and the land is steep and rocky. The target deposit is an approximate four- <br />acre outcrop approximately 20 feet deep. The mine will be developed in phases not <br />to exceed five acres at any one time but may be smaller based on sandstone <br />integrity. In the event sandstone quality is consistent, vertical mining will continue <br />constructing eight foot benches every ten vertical feet. Upon exhaustion of quality <br />sandstone within the four acre delineated area, mining may move east if sandstone <br />quality warrants. Sandstone rubble will be harvested from the surface for <br />approximately two to three years before deposit extraction will be necessary. This <br />will be a dry mining operation and mining operation will be consistent throughout the <br />life of the mine. <br />The proposed mine will operate Monday through Friday from sunrise to sunset <br />when a KrauthCo Inc client requires the sandstone. Based on business history, the <br />site has the potential to operate approximately eight months of the year. The mine <br />will operate on an on-demand basis with maximum extraction less than 70,000 tons <br />per year. The projected life of the mine is approximately 30 years. The initial 4.1 <br />acres has a projected life of approximately five years including surface rubble <br />harvesting. Subsequent mine acreage will be dependent upon the exposed <br />sandstone character but will be within the 35 acre permitted boundary. <br />Using a rubber-tired -skidsteer or rubber-tired excavator, sandstone slabs will <br />be lifted from the deposit and loaded onto five ton truckers for hauling to either the <br />client address or KrauthCo Inc equipment storage yard at 1068 Red Canyon Road, <br />Canon City, Colorado. In the event topsoil or overburden is encountered, the <br />material will be stockpiled for use during reclamation. <br />The initial mine phase will be limited to 4.1 acres as delineated on Exhibit C. <br />Subsequent mine phases will be limited to up to five total acres and will follow <br />sandstone integrity to the north and east. This area contains the extraction sites <br />previously mined. Mine development will occur as 10 feet high 8 feet wide benches <br />along the developing east wall of mine. The mine will daylight to the south and <br />west, the ravine facing side of the deposit. <br />Stormwater berms will be either straw bales, waddles or constructed of <br />overburden if available as required by Colorado Department of Public Health and <br />Environment's Water Quality Control Division. No mining activity will occur within <br />the ravine. Historic drainage will be maintained during mining. All diversionary <br />structures would be temporary and will be removed during reclamation. Stormwater <br />will be directed into the natural ravine along the west side of the target deposit. <br />Explosives will not be used during mining. <br />Page 5 of 25 <br />Revised 3/14/2011
