The <br />gravel and overburden volumes are based on computer grid files of the current topography and <br />the mined out topography. The distribution of gravel and overburden is based on the current <br />operation which produces 1 cubic yard of overburden for every 2 cubic yards of gravel. <br />The table above uses tons for gravel and cubic yards for overburden, and topsoil as units of <br />measurement since they are industry standards. <br />Highway trucks will haul sellable material to market from the processing site. Truck traffic will <br />utilize Clear Fork Road and Highway 92. <br />The gravel is estimated to have a flat bottom at 6948'. This was estimated from the current pit <br />floor in the existing Mining Area 1. It is expected that the bottom will slope slightly to the north <br />2. Mining Timetable <br />The following table (Table C-2) is a best estimate of the sequence of operations for the life of <br />the mine and is based on producing 12,000 tons per year. This may change due to the <br />inconsistent demand in the area. It is projected the majority of the material will be sold for <br />highway construction and local use. Mining is planned to be completed by 2017. <br />Mott pit, March 2009 C-2
