cn <br />to Deposits to be extracted are a thoroughly indurated, hard, fine-grained sandstone bed of the lower <br />Cretaceous Period Dakota sandstone with a varying thickness of from 30 to 75 feet thick. The <br />sedimentary deposit is slightly undulated from uplifting of the region and lies with an <br />approximate dip of up to 5'/z degrees to the north within the permit area. Mining will most likely not <br />reach the bottom of the sandstone bed. <br />~, Underlying material below the Dakota sandstone is a soft gay Cretaceous Period mudstone. <br />mi <br />The primary commodity to be mined, produced, and marketed is crushed and sized rock products. <br />"Oversized' shot rock that is too large to fit into the crusher jaw shall be segregated, sorted, and stockpiled, <br />to be sold as rtp rap of various specification dimensions. Rock products are to be sold off-site on the open <br />market for road and other construction materials. <br />m~ <br />There is no secondary product. <br />in <br />Explosives are to be used in each successive extraction `shot' of the in-place sandstone deposits, but <br />explosives will not be stored on-site. <br />(END] <br />-t5- <br />I/S2QD6 DMCII2 AppL PEEKINS SANDSTONE <br />
