EXHIBIT L—Reclamation Costs <br /> The expanded MMM Partnership Pit will have a total of 59.2 acres. While not yet released <br /> approximately 13.6 acres within the original permit have been mined and revegetated. This reduces the <br /> net effective area to be reclaimed to be 45.6 acres. This includes 14.2 acres of the original 112 permit <br /> and an additional 31.4 acres in the proposed area. <br /> 1) The area of excavation will be mined as close to a 3:1 slope as possible and finished at a 3h:1v as <br /> possible. <br /> 2) All topsoil will be re-applied to the excavations lying outside of the sand drainage. No significant <br /> overburden is anticipated. <br /> 3) The slopes will be prepared and seeded as recommended by the Natural Resource Conservation <br /> Service. <br /> 4) A per acre estimate of reclamation costs is attached. <br /> 5) The pit will be mined in phases not to exceed 10 acres of mining before sloping,top soiling and <br /> seeding will be performed. This includes approximately 8 acres of excavation and 2 acres of <br /> product stockpiles where minimal disturbances will occur. This is an effort to practice good <br /> stewardship of the property by allowing the depleted areas a greater period of time to <br /> revegetate during the mining process. Thus, reducing the long-term bonding liability of the <br /> permit. <br />
