EXHIBIT D -MINING PLAN <br />' The entire affected area contains clean to silty sands extending <br />' from the existing ground surface to various depths be tow the surface. <br />Eight exploratory test holes drilled in the excavation area at the site <br />indicate masonry-type sand to depths ranging from 12 to 42 feet with <br />' clay strata appearing in the south and west portions of the excavation <br />area. Underlying the sand deposit is bedrock consisting of cLaystone <br />t and interbedded sandstone. The report on the exploratory borings by <br />t CTL/Thompson, Inc. is enclosed at the end of this exhibit to provide <br />' specific details concerning the soils encountered in the investigations. <br />Because the site is an open drainageway which receives periodic <br />' flooding and deposition of sand, the vegetation is sparse. Grubbing and <br />' removal of overburden will be minimal, and the operation will involve <br />merely the removal of the sand (along with the clay strata where it <br />' exists) with some washing and grading to provide a finished product. <br />' Extraction of the sands will be accomplished by open pit and/or <br />dredging methods. The excavation area will be divided into eight <br />' tracts, with extraction of materials being performed in one tract at a <br />' time (see Mining Plan Map in Exhibit C depicting the mined and <br />affected areas). <br />' The operation will commerce with the removal of topsoil, if any, <br />' to be stockpiled in the washing plant area which is above and removed <br />from the established flood plain. The raw sand will be extracted from <br />1 the ground by means of a front end Loader, scraper, or dragLine and <br /> <br /> <br />
