San Luis Project CDMG Annual Report March 17, 2004 Page 2 Field activities associated with the contractual agreements for the demolition, removal and reclamation of the crusher/mill facilities completed with SVL Earthmovers, Inc. (SVL) in December 2002 were initiated. SVL and their partner A.M. King Inc. (King) of Oroville, California initiated mill removal and facility demolition in December of 2003. According to SVL and King, completion of crusher/mill demolition, removal and reclamation is tentatively scheduled for completion during late spring or summer of 2004. The primary roadway surfaces from the Rito Seco county road to the mine equipment parking ditch, as well as the remainder of the South Waste Rock Facility, the mine equipment parking ditch, the mine equipment fuel farm, and mine equipment parking ditch topsoil stockpile reclaimed during the fall of 2003 were reseeded during the fall of 2004. The reseeding was conducted due to the lower than expected plant emergence and density experienced during the growing season of 2004. These lower than expected densities are believed to be associated with using seed supply during 2003 that SVL purchased a number of years ago, it is expected that the seed source germination values were lower than when originally purchased and that some of the supply was more than likely cored out by rodents during the storage period. Therefore, BMRI reseeded these areas to facilitate ample seed supply for the 2004 growing season. Reclamation closure cost estimates were internally reviewed with the preparation of this report and previously comprehensively reviewed with Division during calendar year 2001. The existing financial surety ($7,400,000) was determined adequate to complete the remaining surface land reclamation, fulfill surface and ground water monitoring obligations, and complete water treatment operations associated with the West Pit and Rito Seco alluvial ground water systems in 2001. Since that time, additional reclamation work consisting of 34.96 acres was completed in 2002 reducing the quantity of mine land reclamation required to complete the Project, and the following quantities of West Pit and Rito Seco alluvial groundwater were extracted, treated and discharged to Rito Seco Creek in 2002 (127,985,600 gallons - 392.8 acre-feet) and 2003 (128,173,000 gallons - 393.36 acre-feet). Since, no financial surety reductions were requested in 2002 and 2003; the existing financial surety should be more than adequate to complete the remaining reclamation and closure obligations. Should the Division desire to formally review the surety estimate, BMRI will supply any information necessary. Areas of Disturbance/Reclamation Table 1 below summarizes the San Luis Mine Project areas of disturbance and reclamation. The attached map depicts the remaining areas of disturbance. Site Monitoring and Reporting Quarterly water sample collection and analysis was conducted in accordance with TR-06, TR-15, TR-26, TR-31 and TR-32, and the TR-32 monitoring program and QA/QC Plan. Laboratory analytical reports were transmitted to the Division upon receipt from the laboratory. Monthly surface water, ground water and process point water sampling was conducted in accordance with the applicable technical revisions. Piezometer water level measurements were conducted throughout the year in accordance with the permit frequency presented in the
