Mining Methods <br />The deposit will be dry mined, and a slurry wall will be constructed around the perimeter <br />of the mining area between year two and year three of the mining. Design specifications <br />for the slurry wall and quality control procedures used during construction will ensure <br />that the reclaimed reservoir meets State Engineer's Office (SEO) performance <br />standards. Dewatering trenches will be excavated around the perimeter of each mining <br />area in Phases 2-7 prior to mining operations commencing. <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 <br />equipment. (The plant will be a portable setup.) <br />Earth Moving Equipment <br />Dozers, loaders, scrapers, excavators, and compactors will be used for mining and <br />earth 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 with scrapers to expose <br />the aggregate product below. All soil and overburden material will be used on-site for <br />reclamation; so long-term stockpiling of these materials is not anticipated. Overburden <br />stockpiles will be located within the proposed mining area and placed so that they do <br />not impede potential floodwaters. The stockpiles will be placed outside the floodplain <br />where possible. <br />Mining of the aggregate will progress down to the underlying bedrock. Since <br />reclamation will occur concurrently with mining, it is not anticipated that bedrock <br />material will be stockpiled long-term prior to use if it is used in the reclamation slopes. <br />During mining and at the completion of reclamation, the mining face will have a 3H:1 V <br />slope. The aggregate material will be temporarily stockpiled near the portable plant site <br />outside the floodplain where possible until mining has progressed where stockpiles as <br />well as the portable plant site can be placed below the existing grade within the mining <br />boundary. <br />Mine Phasing <br />Broken Arrow Investments, LLC anticipates mining and reclaiming the Derr Pit Project <br />site in approximately 15 - 18 years. It is anticipated that Broken Arrow Investments, LLC <br />would mine to a depth of 3 - 6 feet in Phase 1 of the mining plan encompassing roughly <br />27.98 acres of the mining limits and groundwater would not be exposed. Phases 2 - 7 <br />would be mined to a depth of 70 - 90 feet with each phase being 4.84 - 6.00 acres. <br />- Derr Pit Project <br />R J&T Consulting, Inc. DRMS 112 Permit
