Rubber Wheeled Excavator <br />During the summer, often a rubber wheeled excavator will be included in the facility <br />equipment. This machine is either a small tractor type back hoe with a front bucket or a <br />skid steer type loader. The type of machine utilized is dependent upon the needs during <br />the operational season. The excavator is used to load and unload underground <br />equipment, move supplies such as mine timber and to distribute waste rock as needed. <br />Trestle Type Rall Car Dumping Pocket <br />This structure is located along the rail path and provides a 10 foot open space under the <br />rail path. It is used to dump waste rock into and any rock that may be transported from <br />the mine site via small dump truck if the need ever arises. To date, the Poorman mine <br />has had no official production but a few small loads of rock were removed for mineral <br />processing type test. <br />Waste Rock disposal Area <br />All waste rock exits the adit portal in 20 cubic foot hand pushed rail cars and is removed <br />from the cars by either dumping them into the dump pocket near the south end of the <br />waste rock pile or by dumping them at the edge of the waste rock pile, at the very south <br />end of the rail path. If it is dumped into the pocket, it is then move via a rubber wheeled <br />loader to the edge of the waste rock pile, just east and south of the dumping pocket. <br />The dumped waste material rest at an angle of repose of 35 degrees. At this angle, <br />vegetation is aggressively growing naturally in the dumped material just west of the <br />current area being filled. Natural vegetation includes Aspen trees, Lodge Pole Pine trees <br />and grass. <br />• Dimensions of Significant Disturbances <br />See Exhibit E Map, Mining Plan <br />• Proposed Roads Used during the Mining Operation <br />There are no new roads that will be required to be constructed for this mining and exploration <br />project. A very short section of existing road will be used to access the portal of the mine and <br />facilities. Please see Exhibit E Map for the dimensions of the existing roads. <br />• Very little water is required to conduct exploration or excavate underground openings. <br />Currently required water is purchased form municaple water supplies in Idaho Springs or <br />evergreen, Colorado and is of drinking water standards and is hauled to the mine via 55 - <br />gallon plastic barrels in the back of a truck. The maximum amount of water required is <br />approximately 55 gallons per day. All water is used underground for drilling and dust control. <br />• Ground Water <br />No ground water has been encountered in the workings of the mine. All exploration and <br />possible mining activities are well above the water table. It is not anticipated that the activities <br />at the Poorman Mine Prospect will impact the ground water hydrologic system. <br />• Possible Acid Generating Rock (PAG) or Toxic Materials <br />5 <br />
