T-r---„ .~.~ ~'Q;t~_.. ~ ~T-_ ocr ^ c, z~~s EXHIBIT L -RECLAMATION COSTS Division otRec;~.mation, Wining anG Saf3iy This revised reclamation cost estimate has been prepared to evaluate the cost obligations associated with the modification to the reclamation plan for the Tailings Disposal Area at the Battle Mountain Resources Ina San Luis Mine in Costilla County, Colorado. This revision accounts for the current (2006) reclamation status of the Tailings Disposal Area and incorporates current wage and equipment rates. Since concurrent reclamation practices were conducted during operations (i.e. 1990-1996) and post-mine reclamation has continued after the October 1996 suspension of operations, considerable reclamation obligations associated with the mining and beneficiation operations have been completed. The Steffen, Robertson, and Kirsten (SRK) reclamation cost estimate (SRK, 1994) and the revised cost estimate in TR-26 (2000) have been used as a template for this estimate. L.1 Unit Costs -Earthwork Current hourly rates for earth moving equipment have been obtained from San Luis Valley (SLV) Earthmovers of Monte Vista, CO. SLV Earthmovers has been contracted to complete site reclamation activities. All calculated unit rates for reclamation construction assume the use of SLV Earthmover equipment.
