<br />(,~ EXHIBIT D <br />MINING PLAN <br />Mining will be accomplialied in 6 phases as outlined below with stripping, <br />~backfilling, and quarrying going on simultaneously. The overburden <br />material consists of sandstone rock containing SOY, Si02 and SOY (:AC03. <br />This material does breakup and will generate considerable fines which <br />will aid in subsequent revegetation. The underlaying bed is aga:Ln sand- <br />stone rock with the same chemical composition as that of the overburden. <br />The parting plan between the limestone and the underlying sandst~~ne is <br />clearly defined, which results in a smooth hard floor after the .Limestone <br />is removed, Thie would be very close to the existing tertian which ie <br />rock outcropping. <br />• Conventional open pit quarrying methods will be used in this operation.. <br />i _ 1 <br />Both the sandstone overburden and limestone will be drilled and blasted. <br />The shot rock will then be loaded and hauled Co the crushing, screening, <br />and stockpiling area. Necessary roads will be constructed as required <br />to provide access to the mining operations. The roads will be constructed <br />primarily with the overburden material and covered with 3" to 12" of <br />3/4 minus limestone. Roadways will not need to be constructed outside <br />the disturbed area and will be graded, covered or scarified to facilitate <br />revegetation. <br />~~ <br />
