EXHIBIT D <br />MINING PLAN <br />Mining will be accomplished in 7 phases as outlined below with <br />stripping, backfilling, and quarrying going on simultaneously. <br />The overburden material consists of sandstone rock containing <br />SO% Si02 and 50% CAC03. This material does breadup and will <br />generate considerable fines which will aid in subsequent revege- <br />tation. The underlaying bed is again sandstone rock with the <br />same chemical composition as that of the overburden, The parting <br />plan between the limestone and the underlying sandstone is clearly <br />defined, which results in a smooth hard floor after the limestone <br />is removed. This would be very close to the existing terrian <br />which is rock outcropping. <br />Conventional open pit quarrying methods will be used in this <br />! operation. Both the sandstone overburden and limestone will be <br />i drilled and blasted. The shot rock will then be loaded and hauled <br />e~~ <br />to the crushing, screening and stockpiling area, Necessary roads <br />will be constructed as required to provide access to the mining <br />operations. The roads will be constructed primarily with the <br />overburden material and covered with 3" to 12" of 3/4 minus lime- <br />stone. Roadways will not need to be constructed outside the <br />disturbed area and will be graded, covered or scarified to <br />facilitate revegetation. <br />•/ <br />
