FLAG RESOURCES, INC. <br />SILT PIT <br />M_L.R.B. Permit # M-81-202 <br />BOND CALCULATION WORK SHEET (.lune 19,201-7) <br />This reclamation cost estimate is based on not disturbing more than 50.00 <br />acres t at any one time. This includes areas stripped, partially mined <br />and partially reclaimed. The table below outlines the baseline data we <br />used to do our calculations. This includes the resoiling and <br />revegetating the batch plant area, the processing area and the above <br />water areas disturbed by mining. Also an estimate to dewater the east <br />lake during reclamation is included. It includes using an electric pump <br />since power is available at the mine. Pumping time estimate is attached. <br />DESCRIPTION <br />TOTALS <br />AREA NEEDING REVEGETATION <br />50.00 <br />ac. <br />LAKE AREA <br />32.00 <br />Re -spreading soil and/or growth media using <br />NEEDS RESOILING <br />50.00 <br />ac.
