<br />EXHIBIT D <br />M[NING PLAN <br /> <br />Mining will be accomplished in 6 phases as outlined below with stripping, backfilling, and <br />quarrying going on simultaneously. The overburden material consists of sandstone rock <br />containing SO~Yo Si02 and 504'o CAC03' This material does breakup and will genera[~~ <br />considerable fines which will aid in subsequent revegeta[ion. The underlaying bed is again <br />sandstone rock with the same chemical composition as that of the overburden. The parting plan <br />between the limestone and [he underlying sandstone is clearly defined, which results in a <br />smooth hard floor after the limestone is removed. This would be very close to [he existing <br />[errian which is rock outcropping. <br />Conventional open pi[ quarrying methods will be used in [his operation. Both the sandstone <br />overburden and limestone will be drilled and blasted. The shot rock will then be loaded and <br />hauled to the crushing, screening, and stockpiling area. Necessary roads will be constructed as <br />required [o provide access to the mining operations. The roads will be constructed primarily <br />with the overburden material and covered with 3" to 12" of 3/~ minus limestone. F:oadways <br />will not need [o be constructed outside the disturbed area and will be graded, covered or <br />scarified [o facilitate revege[ation. <br />
