Plan Map, and the Slope Stability Report for the mining limit configuration and information on <br />setbacks and their locations. <br />Products <br />Sand and gravel will be the primary product produced from the Journey Ventures Pit site. The <br />principal intended use for the sand and gravel is for road base and construction aggregates. <br />Subsurface drilling and testing has verified that the Journey Ventures Pit property contains a <br />significant commercial deposit of sand and gravel. The depth of the overburden ranges from 2 <br />to 5 feet. The thickness of the aggregate material ranges from 55 to 80 feet. The overall depth <br />to bedrock ranges from 51 to 107 feet. <br />Mining Methods <br />The deposit will be dry mined and a slurry wall will be constructed around the perimeter of the <br />mining area either prior to Phase 3 or at some point between Phases 3 and 11 of the mining. <br />Design specifications for the slurry wall and quality control procedures used during construction <br />will ensure that the reclaimed reservoir meets State Engineer's Office (SEO) performance <br />standards. Dewatering trenches will be excavated around the perimeter of each mining area in <br />Phases 3-11 prior to mining operations commencing. The depth of the ditches will vary as the <br />mining progresses deeper into the alluvium in order to maintain the groundwater level below the <br />active mining bottom surface, and therefore minimize the exposed groundwater surface area. <br />The dewatering ditches will flow to a collection pond, from which the water will be pumped into <br />an irrigation lateral, which traverses the site and eventually discharged into the South Platte <br />River. <br />The equipment and facilities may include, but are not limited to the following: <br />Processing Equipment <br />Screens, crusher, conveyors, stackers, and other miscellaneous processing equipment. <br />Earth Moving Equipment <br />Dozers, loaders, scrapers, excavators, and compactors will be used for mining and earth <br />moving operations. <br />Miscellaneous Equipment <br />Dewatering pumps, electrical trailer, generator trailer, small portable generators and <br />watering trucks will be used as needed. <br />As mining progresses, topsoil and overburden will be stripped to expose the aggregate product <br />below. All soil and overburden material will be used on-site for reclamation; so long-term <br />stockpiling of these materials is not anticipated. Overburden stockpiles will be located within the <br />proposed mining area. The stockpiles will be placed outside the floodplain. <br />Mining of the aggregate will progress down to the underlying bedrock. Since reclamation will <br />occur concurrently with mining, it is not anticipated that overburden or bedrock material will be <br />stockpiled long-term prior to use in the reclamation slopes and in production of road base. <br />During mining the mining face will have a 3H:1V slope for the top 13 feet starting at an elevation <br />of 4594 in most cases, and then transition to a 2H:1 V slope to bedrock or the bottom of the <br />future reclaimed reservoir. A 3H:1 V slope will be used at all locations above the anticipated <br />normal water surface elevation of 4591 once the pit is reclaimed as a water storage reservoir. <br />Journey UT Consulting, Inc.
