<br />EXHIBIT D <br />MINING PLAN <br />Mining will be accomplished in 6 phases as outlined below with stripping, <br />backfilling, and quarrying going on simultaneously. The overburden <br />material consists of sandstone rock containing 50% 5102 and SO% CAC03. <br />This material does breakup and will generate considerable fines which <br />will aid in subsequent revegetation. The underlaying bed is again sand- <br />stone rock with the same chemical composition as that of the overburden. <br />The parting plan between the limestone and the underlying sandstone is <br />clearly defined, which results in a smooth hard floor after the limestone <br />ie removed. This would be very close to the existing terrian which is <br />rock outcropping. <br />~ Conventional open pit quarrying methods will be used in this operation. <br />Both the sandstone overburden and limestone will be drilled ;ind blasted. <br />The shot rock will then be loaded and hauled to the crushing, screening, <br />and stockpiling area. Necessary roads will be constructed a:: required <br />to provide access to the mining operations. The roads will tie constructed <br />primarily with the overburden material and covered with 3" to 12" of <br />3j4 minus limestone. Roadways will not need to be constructed outside <br />the disturbed area and will be graded, covered or scarified t:o facilitate <br />revegetation. <br />i <br />~~ i <br />
