ALBERT CREI AND SON B, INC. PAGE 2 <br />BOND EBTIMATE - EXIBTING CON DITTO NB <br />JULY 2B, 2002 <br />will be located on the bottom of the face. Since this toe slope <br />is part of the wall area we have included it in the costs to <br />resoil and revegetate it as if it were a bench. <br />The method used to revegetate the benches will remain as <br />currently permitted. According to this scenario, Frei will have <br />to respread 20,472 cubic yards of soil; do 241,618 cubic yards of <br />cut work on the benches; and revegetate 14.19 ac. t. The amount <br />of soil that will be re-spread is based on an average of 12 <br />inches. Our cost estimate to do all of the shaping in this cost <br />estimate is based on using a D-8N dozer for the cut work; a 988 <br />loader for resoiling, and a 140G Blade to shape and grade the <br />mine floor. Blasting costs are all inclusive in that they <br />include the cost for drilling, dust control, blasting materials, <br />powder delivery, labor to load and supervise the blast prepara- <br />tion, and grading the benches after the blasting is complete with <br />a D8N dozer. The revegetation cost figure includes grass seed, <br />mulch, chemical fertilizer (ammonium nitrate & superphosphate) <br />and drilling costs. The tree costs include the materials and <br />planting labor. <br />The volume of material that will be moved to create each <br />bench is found on TABLE A. Each bench varies in width from 10 to <br />61 feet wide and from 5 to 30 feet high. The bench lengths vary <br />from top to bottom as shown on Figure RC-1. The following table <br />is a recap of the various information provided in the supporting <br />data and figures that follow this text and used on the calcula- <br />tion page. <br /> STAGE (UNITS AC., LFT, CY SO- <br />FT OR PIECES) <br />RECLAMATION ACTIVITY 1 Y SOIL <br />PILE TOTALS <br />REBOIL 12.69 0.00 - 12.69 <br />REVEGETATE 12.69 0.00 1.50 14.19 <br />COMMERCIAL AREA 33.76 0.55 1.50 35.81 <br />UNROADABLE & SCRAP LOADS 35 - - 35.00 <br />BENCH AREA BLASTING 241,618 - - 241,618 <br />TOE SLOPE SHAPING 66,667 - - 66,667 <br />DEMOLITION 270 - - 270 <br />ROADS 1.17 0.25 - 1.42 <br />TREES 300 - - 300 <br />LIST OF FIGURES AND TABLES TO BE USED WITH THIS ESTIMATE. <br />• TABLE A - RECAP OF AREA NEEDING RECLAMATION <br />• DATA SHEET - INFORMATION PERTINENT TO THIS ESTIMATE. <br />• FIGURE RC-1 - EAST AND NORTH WALL PLAN VIEWS. <br />• FIGURE RC-2 - EAST WALL - SOUTH AREA - SECTION B-B' <br />• FIGURE RC-3 - EAST WALL - NORTE AREA - SECTION A-A' <br />• FIGVRE L-4 - TOS SLOPE CROSS SECTION <br />
