exposure for the infiltration pond will be limited to a maximum of 32230 square feet (.74 acres). <br />This gives a total surface water exposure of 1.37 acres. <br />Section 2.0 General Geology of Site <br />The geology of the site is best described as the upper reach of the South Platte River in <br />Pliestocene glacial moraine gravels mixed with some Quaternary gravels of recent age. Sand beds <br />and clay beds are also interspersed with the alluvium. Depths of this material range from 30' to <br />100' within the permit area. These gravels overlay a bedrock of pre - Cambrian schist, gneiss and <br />intrusive granite, which are also present in the mountains on both sides of the permit area. Only <br />minor stratification has been seen in the gravels since boulders of 10 " -15" size are found in some <br />sand beds, probably from glacial meltwater. The gold veins in igneous rock on the south side of <br />Hoosier Pass and in the upper basin of the South Platte drainage are the origin of the placers <br />through thousands of years of glacial activity during the last ice age and subsequent erosion . Due <br />to the fineness of the gold at the site (0.833 fine), the gold placer has been traced to gold from <br />North Star Mountain in the Montgomery Deadwood area in the upper reach of the basin. <br />Section 3.0 Gold and Gravel Mine Facilities <br />The gold and gravel mine operation will consist of the following facilities: <br />- portable gold processing plant (may be sluice, jigs, bowls, cyclones or other equipment) <br />- truck scale with small portable scale office <br />- assorted power poles delivering power to the camp area <br />- 2 portable trailers for employee temporary housing 1 -8' x 40', 1 -14' x 70' on metal skids <br />- 1 office trailer on metal skids 14' x 38' <br />- 2 porto- potties for employees and visiting personnel <br />- equipment and material storage on skids or palettes for easy removal <br />Gloria Z Mine 2013 Amendment 8 <br />
