DIVISION OF MINERALS & GEOLOGY BOARD PERMIT AMENDMENT APPLICATION <br />REGULAR OPERATION (112) <br />PERMIT # M-1992-066 <br />ROGUE RIVER PIT <br />EXHIBIT D Mining Plan <br />overburden removal. Very little, if any, of this material should require stockpiling <br />prior to backfilling in the pit excavations. <br />Gravel reserves will be mined with an excavator and loaded on haul units to be <br />transported to the processing area. Exploratory tests have indicated that varying <br />sizes of gravel will be encountered during mining operations. This material will <br />be separated accordingly and transported to the proper processing area and <br />stockpiled. If unsuitable material is encountered during mining operations, the <br />material will be separated at the excavation and will be used as backfill in the pit <br />excavation. The mining operations is benched to make full utilization of the <br />existing gravel reserves. Benching requirements ate determined by the depth of <br />the gravel reserves and safety considerations <br />5. The excavated interior pit slope will be a minimum of 3:1 slope from existing <br />ground to ten feet below water and 2:1 gradient from there to the bottom of the <br />excavation. Perimeters of the pond area at or near water level maybe "flattened" <br />to create additional wetland areas. <br />6. There will be one processing operation on site. This will consist of a crushing and <br />screening operation that will include a commercial crusher set up with <br />miscellaneous conveyors and screens and a wash plant with conveyors. <br />Materials to be processed on site will include the following: <br />a. Pit Run <br />b. Road Base <br />c. Screened Rock <br />d. Washed Rock <br />e. Cobble <br />f. Crusher Rejects <br />g. Sand <br />h. Miscellaneous Gravels <br />In addition, other materials may be processed on site and/or utilized as required <br />for local markets. Some of these materials may include: <br />
