Exhibit L <br />Reclamation Costs <br />JD -9 Mine Permit Amendment <br />M- 1977 -306 <br />The worst case reclamation scenario is based on the current conditions at the JD -9 Mine. <br />Table L -1, JD -9 Reclamation Costs <br />Mine Waste and Portal Area Cost <br />1. Remove culvert $2,470 <br />2. Re- contour waste area $10,500 <br />3. Pocking waste area $3,150 <br />4. Removing all surface facilities $34,240 <br />5. Removing liners and precipitates $6,400 <br />6. Radioactive testing of the pond area $1,560 <br />7. Scrape the top material from ore pad $240 <br />8. Seal portal $40 <br />9. Re- contour treatment ponds $551 <br />10. Reclamation of ventilations shafts $14,320 <br />11. Replacing topsoil $1,162 <br />12. Ripping topsoil $240 <br />13. Seed $1,560 <br />14. Hydroseed and mulch $4,140 <br />15. Mobilization costs $4,800 <br />Total $86,933 <br />The worst case reclamation task items are described below and correspond to the tasks as shown in Table L -1: <br />1. Removing waste material and the associated culvert from the drainage immediately west of the portal <br />area and waste embankment A track hoe will remove the roughly 1,300 cubic yards of waste and place <br />it in trucks which will then haul the material to the top of the waste pile for a bulldozer distribution. A <br />small portion of this material will be used to seal the mine portal. See Task 8. It is estimated that the <br />combined cost will be $1.90 per cubic yard. The cost for this task is $1.90 cy x 1300 cy = $2,470. <br />2. Regrading the waste pile to a 1.8H.•1 V slope with a bulldozer Currently, it is slightly steeper <br />(1.5H:1 V). This quantity, calculated in Survcadd, is 14,000 cubic yards. This will require an average <br />dozer push of approximately 30 feet vertically up or down. The upper slopes will be brought upward <br />and the material, from the midway point downward, will be pushed down. The estimated unit cost for <br />this work is $0.75 per cubic yard. The cost for this task is $0.75 per cy x 14,000 cy = $10,500. <br />L -1 <br />
