*6.4.5 Exhibit E- Reclamation Plan <br />6.(1) Provided in Rick Romano's updated letter of 4/11/2012 <br />included. <br />(II) Mine site sediment pond will remain after reclamation. <br />(III) The 20 foot high stockpile site retention berm will not remain <br />after reclamation as this material will be utilized as capping material <br />for reclaiming. <br />*6.4.6 Exhibit F- Reclamation Plan Maps <br />Revised maps show mine site map as Exhibit F and stockpile site <br />maps Exhibit F -1 <br />*6.4.9 Exhibit I -Soils Information <br />8. As shown on maps, stockpile site is located on south side of mine <br />access road, which is Alkali Gulch. See revised NRCS report. <br />*6.4.10 Exhibit J- Vegetation Information <br />9. See NRCS report included. <br />*6.4.12 Exhibit L- Reclamation Costs <br />10. Stockpile site was not included in Exhibit L but was on page 10 of <br />application showing a reclamation cost of $14000.00 <br />*6.5 Geotechnical Stability Exhibit <br />11. All walls are to be constructed to 2:1 slopes with 20 feet wide <br />benches. All of pit is consistent material. <br />By constructing all slopes to a 2:1 with benches, this will allow us to <br />machine place schist type material on slopes with the benches to <br />help curtail erosion. By flattening all slopes to this extent, there will <br />be no stability issues. <br />
