PERMIT AMENDMENT <br /> PERMIT #M-77-219 <br /> DESCRIPTION OF AMENDMENT: <br /> A recent survey of the mine site was completed. This amendment is <br /> made to update maps and plans to more accurately reflect the <br /> current situation and amend the permit boundary. A revised cost of <br /> reclamation is also included. <br /> EXHIBIT A - LEGAL DESCRIPTION <br /> NW 1/4 SE 1/4 and SW 1/4 NE 1/4 Sec . 30 T22S R67W <br /> EXHIBIT B - INDEX MAP <br /> See attached EXHIBIT C <br /> EXHIBIT C - PRE-MINING & MINING PLAN MAPS <br /> See attached. <br /> EXHIBIT D - MINING PLAN <br /> All available top soil will be removed prior to disturbing any <br /> area. It will either be stored for future application or will be <br /> spread over areas previously graded to final slope. This will be <br /> accomplished using a dozer or scraper, depending on the distance <br /> that the soil is to be moved. <br /> The remaining overburden on the clay vein will be drilled and <br /> blasted. Removal will be by dozer. This material is primarily <br /> sandstone with minor amounts of sandy clay. <br /> The exposed clay is then removed using loader and truck. The <br /> stratum underlying the clay vein is very sandy clay and sandstone. <br /> Each cut or individual mining block is normally 1/4 to 1 acre in <br /> size. The overburden from each cut is placed in previously mined <br /> out areas . The entire sequence is in the Dakota sandstone <br /> formation. <br /> As mining is completed in each area and no further disturbance is <br /> planned, the area will be final graded and reseeded for reclamation <br /> purposes . mining is currently conducted in three areas designated <br /> as Pit Areas No. 1 (south) ; 2 (north) ; and 3 (east) . Each area <br /> contains different quality and type clays . Mining is conducted in <br /> each area based on the need for each type of clay. <br />
