• <br />EXHIBIT D <br />Mining Plan <br />F~chibit D map displays the phasing of mining and reclamation for the Camilletti Pit. <br />Activities at the pit include material extraction, handling, stockpiling and hauling. The <br />southern expansion of the pit will be performed using standard gravel mining practices <br />with the extensive use of front-end loaders and occasionally hydraulic excavators and <br />scrapers. Scrapers are utilized for topsoil and overburden removal and during <br />backfilling and reclamation. Phased mining will be coordinated with the removal and <br />stockpiling of topsoil and overburden, and backfilling and reclamation to minimize the <br />amount of disturbances at any one time. The purpose of the mining activity is to provide <br />aggregate and related products, especially pit run, base course gravel (road base), and <br />overburden for structural fill and road projects. Pit run gravel will either be loaded <br />directly into haul trucks or moved to the crusher. Specification aggregates will be <br />crushed and produced on a limited basis depending on our future projects and <br />contracts. Materials, topsoil, and overburden will be stockpiled on the pit floor. There <br />will also be stockpiling of topsoil and overburden in berms around the pit. <br />1. Dates of Mining: Connell Resources, Inc. antidpates mining the Camilletti Pit for a <br />ten-year period. Mining will continue this year with the can-ent 110c permit and based <br />upon approval mine to the year 2010 with the 112c permit. The mining area per year <br />will average between one to two acres. <br />2. Depth of Salvage Topsoil: Recent exploraton test pits in the southem expansion <br />area indicated an average topsoil thickness of six inches. This is consistent with the <br />original 1987 SCS soil investigation and historic mining in the pit. Topsoil stripping will <br />also be phased with mining and reclamation to minimize disturbances. Topsoil <br />stockpiles will be located in berms along the pit perimeter at the top of the slopes and <br />will be maintained separately from the other stockpiles. Topsoil may also be stockpiled <br />on the pit floor. Sorrre of the stockpiled topsoil will be used for slope reclamation that <br />will be concurrent with mining. Topsoil that is going to be stockpiled for more than one <br />growing season will be seeded. <br />3. Overburden Thickness: The recent exploration test pits in the southem expansion <br />area showed the overburden to range from 8 to 14 feet in thickness. The overburden <br />will be use in slope backfilling and re-grading prior to topsoil replacement. The <br />
