EXHIBIT "D" <br />Mining Plan <br />6.4.4 Exhibit (D) Mining Plan <br />All areas to be mined are considered high and dry with no groundwater to be encountered <br />during mining. The deposit is fairly deep, ranging from 0.5' deep to possibly 45' deep, <br />along the upland deposit. <br />Excavation is to be an open pit with the Gse of standard mining equipment used for such <br />operations, eg. Scraper, dozer, wheel loaders, excavators and draglines. However, due <br />to the life of this mine, other types of equipment not yet economical for gravel may be <br />employed in the future. <br />Processing will take place on site in order to size by crushing and screening, and some <br />reject material will be used for final reclamation. Also a concrete and/or asphalt batch <br />plants will be erected on site as needed for projects in this part of the state of Colorado. <br />If the demand is sufficient to warrant they may become permanent for the life of the mine. <br />As much as possible, mining will be conducted in such a way as to facilitate reclamation, <br />such as pushing slopes to a 3H:1V when practical. Reclamation will follow in a timely <br />manner once an area is deemed mined-out. Seeding and final grading will be to a final <br />reclamation use of rangeland, which the landowner has prescribed. <br />The following will address the items listed under Rule 6.4.4 - Exhibit D - in order of <br />appearance: <br />Please see Mining Plan Map for more information and correlation's. <br />6.4:4(a) <br />Like similar open-pit sand and gravel operations, this pit will be stripped of the available <br />topsoil (growth medium) by earthmoving scrapers and loaders, and will be placed along the <br />areas bounding the mining areas and left in place until needed for re-topsoiling. These <br />topsoil stockpiles will be seeded to reduce soil erosion. <br />(b) All earthmoving will be done by mining equipment suitable for this type operation, <br />including the following types: crawler dozer, wheel loaders, earthmoving scrapers, <br />excavator, draglines, and haul trucks of various sizes up to and including haul units with <br />a 50-ton capacity. Over-land conveyors may also be employed during the I'rfe of this mine <br />to transport material to the processing areas. <br />(c) The only water diversions would be for stormwater management to keep all stormwater <br />from running into or off site, and for erosion control. <br />
