Exhibit D-2 displays the mining plan overview for 2025 through 2028. These area will be mined to <br /> depths that allow drainage but will not exceed 25' below the pervious pit floor. The dry screening <br /> plant and stockpiles will be moved as the mining progresses. Product stockpiles will mostly remain <br /> in the pit. Ramps and service roads will be kept convenient for trucking and mine equipment. <br /> Exhibit D-3 displays the forecast mining plan for the North Pit in 2029-2030. The North Pit's SW <br /> side is open and overlooks the Arkansas River. Drainage will be directed towards the river with <br /> cutoff ditches for seepage and floor slopes for sheet runoff. <br /> The North Pit is currently used for stockpiles of stripped overburden and crushed road base. Access <br /> is through the Buffer Area to the east of the MRA. The roadway is at-20 feet from original surface <br /> elevation. Alternatively, the North Pit can be accessed by ramps up and over the MRA. <br /> .- 7 'C' <br /> 4/ `^ t^� s aaia sera acre.a <br /> � 1 <br /> is <br /> � h 150 <br /> � s ^ <br /> 1 Butala Gravel Pit—Salida, CO - <br /> EXH.

The deposit is very clean without any clays or silts. Minor <br /> amounts of calcite, stone dust and weathered sand are the only fraction less that#200 and no soluble <br /> clays are present. Commercial production is mainly for screened cobble to be used for landscape <br />
