BMRI San Luis Project

and the Telesto survey it appears this discrepancy is primarily associated with certain
facilities which previous surveys identified the facility entirely reclaimed, but failed to
recognize and delineate features such as access roadways or other area disturbances
contained within the reclaimed facility footprint as still requiring final reclamation.
Contractual agreements for the demolition, removal and reclamation of the cnrsher/mill
facilities were completed with SLV Earthmovers Inc. (SLV) during December 2002.
Completion of the contracted crusher/mill demolition and reclamation of the mill area
site must be finalized prior to Apri12005 or SLV will forfeit their posted financial surety
and BMRI will finalize any uncompleted demolition or reclamation work.
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 the mine equipment parking ditch topsoil
stockpile were reclaimed during the fall of 2002. Each of these areas were regraded,
topsoiled, seeded with the approved seed mixture and the topsoil material amended with
approximately ],800 lbs. of commercial organic fertilizer (i.e., Biosoil Plus). Materials
excavated from the geomembrane lined mine equipment fuel farm were tested and managed
in accordance with Division recommendations and approval. BMRI retained Terracon of
Wheat Ridge, Colorado to sample and characterize these materials. A copy of Terracon's
characterization report is attached for the Division's review.
Reclamation closure cost estimates were reviewed with the Division during calendar year
2001. The existing financial surety was determined to be adequate to complete the
remaining surface land reclamation, fulfill surface water and ground water monitoring
obligations, and complete water treatment operations associated with the West Pit and Rito
Seco alluvial groundwater systems at that time. Since that time, additional reclamation
work consisting of 34.96 acres was completed during 2002 reducing the quantity of mine
land reclamation required to complete the Project, 127,985,600 gallons {392.8 acre-feet) of
West Pit and Rito Seco alluvial ground water was extracted, treated and discharged to Rito
Seco Creek in 2002, and since no bond reduction was requested during 2002, the existing
financial surety should be adequate to complete the remaining reclamation and closure
obligations. Should the Division desire to formally review the bond estimate, BMRI will
supply any information necessary.
