MINING PLAN
1. General Mining Plan
EXHIBIT D
The access to the site will be via US Highway 50. See Map C -2 for the extents of mining. As
shown on this map, mining will occur in two stages, where the first stage take place in the main
eastern excavation area, and the second stage in the smaller, west excavation area. Table D -1
shows the quantities for each stage.

The material volumes described in Table D -1 are based on 12 inches of topsoil, an average of
four feet of overburden, and the remaining depth being sand and gravel. This was determined
during exploration drilling. Note that the areas above only include mining areas. The anticipated
total disturbed area for the operation consists of 72.70 acres. Only 60.56 acres of this is mining,
the rest is the sediment pond, berms, roads, and the office /scale area.
At the beginning of the operation topsoil and overburden will be stripped from the processing
area on the south side of the Stage 1 pit to build the processing berm (Map C -213). This material
will be used in reclamation when the processing area is mined. Topsoil and overburden will be
stripped in advance of mining. The topsoil stripped in the beginning of Stage 1 will be used to
build the Signal Peak berm and the Highway berm (Map C -213). These berms are permanent, and
therefore will be seeded upon completion with the permanent rangeland seed mix. Berm volume
requirements can be seen in Table D -3. Topsoil from initial mining will be used on the
processing area berms to improve vegetation on said berms.
Sand and gravel will be directly loaded into the crusher and screener. It will be excavated from
the pit highwall with a front -end loader. Once crushed and screened the sand and gravel will
either be sold as crushed rock, or used in the production of asphalt and concrete. Stockpiles of
