SUMMARY OF WORK

The Cookes Peak West Mine Safeguard Project – Phase IIIB area is approximately 20 miles north of the town of Deming, in Luna County, New Mexico.

• Construction of two Custom Steel Gates (see figure 5), materials and equipment delivered by helicopter to difficult access sites, constructed on vertical shafts;

• Construction of two Standard Steel Gates (see figure 3), materials and equipment delivered by helicopter to difficult access sites, constructed on vertical shafts;

• Construction of six Standard Steel Gates (see figure 3), constructed on three vertical shafts, two adits, and one decline adit;

• Construction of two steel fences (see figure 11) around open stopes;

• Construction of one polyurethane foam plug covered with hand backfill (see figure 9) using mine waste rock and other nearby native rock, constructed in a vertical shaft;

• Construction of three culverts with steel gates in grouted rock bulkhead (see figure 7), one having materials and equipment delivered by helicopter due to difficult access site, constructed in three adits;

• Construction of two dry-stacked rock wall closures, constructed in two adits.
