MINING PLAN <br />6.4.4 Mining Plan Exhibit <br />All areas to be mined are considered high and dry with no groundwater to be <br />encountered during mining. The deposit is deep, ranging from 12 feet deep to possibly <br />18 feet deep, along the upland deposit. <br />Excavation is to be an open pit with the use 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. <br />Mining will be conducted in such a way as to facilitate reclamation, such as pushing <br />slopes to a 3H: 1 V. Reclamation will follow in a timely manner once an area is deemed <br />mined -out. Seeding and final grading will be to a final reclamation use of rangeland, <br />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 correlations. <br />6.4.4 <br />(a) Like similar open -pit sand and gravel operations, this pit will be stripped of the <br />available topsoil (growth medium) by earthmoving scrapers and loaders, and will be <br />placed along the areas bounding the mining areas and left in place until needed for re- <br />topsoiling. All topsoil stockpiles that will remain in one location for longer than one <br />growing season will be seeded to reduce soil erosion. <br />
