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 Pliestocene <br />glacial moraine gravels mixed with some Quaternary gravels of recent age. Sand beds and claybeds are <br />also interspersed with the alluvium. Depths of this material range from 30' to 100' within the permit area. <br />These gravels overlay a bedrock of pre - Cambrian schist, gneiss and intrusive granite, which are also <br />present in the mountains on both sides of the permit area. Only minor stratification has been seen in the <br />gravels since boulders of 10 " -15" size are found in some sand beds, probably from glacial meltwater. <br />The gold veins in igneous rock on the south side of Hoosier Pass and in the upper basin of the South <br />Platte drainage are the origin of the placers through thousands of years of glacial activity during the last <br />ice age and subsequent erosion. Due to the fineness of the gold at the site (0.833 fine), the gold placer <br />has been traced to gold from North Star Mountain in the Montgomery Deadwood area in the upper reach <br />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 sluice plant <br />• trommel and screens <br />• existing office with well and facilities <br />• 1 office trailer <br />• equipment and material storage of skid for easy removal <br />• various plastic water lines delivering water from the pumps to wash plant <br />• front end loader Komatsu 320 <br />• Cat 315 excavator <br />• Haul trucks of 25 -ton capacity <br />• Water surge pond <br />o Water holding pond <br />• Settling pond <br />Sullivan Aggregate Pit March 2015 D -4 <br />
