<br /> <br />EXHIBIT D <br />Mining Plan <br />Mining will be accomplished in 7 phases as outlined below with stripping, <br />backfilling and removal of high calcium limestone of the Leadville <br />formation going on simultaneously. The overburden material consists <br />largely of light grey limestone with minor amounts of soil which is <br />relatively high in magnesium. This material will need be drilled and <br />blasted in order to remove the overburden to uncover the high calcium ' <br />limestone. This blasting and subsequent handling of the material will <br />generate fines which will aid in revegetation efforts. <br />The underlying bed is a dark grey dolomite limestone of the Dyer <br />Formation. The high content of magnesium in this formation makes this <br />bed unsaleable for our current market. <br />Conventional open pit quarring methods will be employed in the operation. <br />The Iow grade limestone will be drilled, blasted and removed using <br />pneumatic track drill equipment for drilling and dozers and front end <br />loaders for the removal of the material. The high calcium Leadville <br />limestone will then be drilled and blasted and then loaded into trucks <br />• for haulage to the stockpile area for crushing and sizing. Necessary <br />roads twill be constructed as required to provide access to the mining <br />operation. The roads will be constructed primarily with the over- <br />burden material and covered with 3 to 12 inches of 3/4 minus limestone. <br />Roadways will not need to be constructed outside the disturbed area. <br />Roads that are constructed will be graded, covered or scarified to <br />facilitate revegetation, <br />• <br />
