Section 1800 3000 tons Section 1900 3600 tons Section 2000 5600 tons Section 2100 8800 tons Section 2200 9800 tons Section 2300 9400 tons Section 2400 9800 tons Section 2500 9800 tons Section 2600 7000 tons Section 2700 7500 tons Section 2800 7900 tons Total tonnage--hangingwall 135600 tons The last ten sections include the Alpha Hill highwa{l on the southern flank of Alpha Hill and the highwall presently found along the north pit boundary of the Copper Hill pit. Both of these highwalls are .25:1 slopes that must be reduced to ]:l rock slopes. These volumes also reflect tonnages necessary to finish grade disturbed areas on North Ridge. OTHER RECLAMATION AREAS TITANIUM DRII,L ROAD REMOVAL AND RECLAMATION In the mid 1980's, core drilling was performed along a roadway circumscribing Titanium Hill, a large gypsum surface outcrop in the Southern end of the Affected land but not within the geologic orientation of the main ore reserve and the sections referred to earlier in this report. Titanium and Uranium Hill were the areas of mining in the 1960's and 1970's, and core drilling and waste removal work in the late 80's proved out app. One million tons of potential gypsum reserve. The core drill roadway and app. Ten acres of disturbed mining ground will be regraded via bulldozer and drilling and blasting on the mine benches. This work will entail app. 10,000 tons of gypsum and limestone rock drilled and shot and app. 25,000 tons of bulldozer work to regrade the areas in question. ROADWAY, BUILDING, AND EQUIPMENT REMOVAL There are a number of structures which must be removed to complete the closure of this mine property, including the primary crushing circuit and supporting equipment (screen, conveyors, dust collector, concrete structures) and blasting materials storage facilities. Approximately one mile of roadway removal will be necessary in addition to the approximately three miles of
