MINING PLAN <br />1. General Mining Plan <br />EXHIBIT D <br />The permit area will be surveyed and marked prior to any new site disturbance. Map C-2A <br />shows the site as of July 2008 and Map C-2B shows the full mining plan for the life of the <br />operation. <br />General Setting <br />The gravel zone is approximately 30 feet thick in an alluvial deposit and is overlain by <br />approximately 20 feet of overburden and topsoil 0-6 inches thick. The gravel deposit will be <br />mined to the shale bedrock layer or to the water table. Mining will stop before groundwater is <br />encountered, and all accidentally exposed groundwater will be promptly buried using overburden <br />or excess fines from processing. The gravels are Florida gravels of the Pleistocene age underlain <br />by shales and sandstones of the Eocene Age. <br />Status as of July 2008 <br />The mining in the northern portion of the pit is complete under the existing permit and the active <br />mining face is in the southern portion of the pit. The approximate contours of the current site are <br />shown on map C-2A. The Valley Fill #1 is complete along with the grass lined channel and the <br />grouted channel that go along with the Valley fill #1. The crushing and screening equipment is <br />brought to the site for a few months out of the year to crush the product for the entire year. A <br />dozer and a loader load the hopper which feeds the processing equipment. The crushed product is <br />taken to the stockpiles by a truck or a loader. There are several large overburden stockpiles in <br />the northern portion of the pit that will be used in backfilling the side slopes. Topsoil is stored in <br />stockpiles to the west of the pit and also on the pit floor. All existing stockpiles are shown on <br />Map C-2A. No groundwater has been encountered in the mining to this point. <br />Cugnini Pit, November 2009 D-1
