O'Conner, Chairman Colorado Mined Land Reclamation Board 423 Centennial Building Denver, Colorado 80203 Re: 1985 Annual Report - Climax Mine; Permit No. 77-493 Dear Mr. O'Connor: The year 1985 was extremely depressed for the mining and minerals industry generally and particularly for molybdenum mining . During the first six months of 1985, the Climax Mine produced an average of 32, 700 tons per day with a work force of approximately 800 people. This rate of production is about 68% of the mine capacity. The workforce was further reduced in July and August to approximately 520, where it remained at the end of the year. From September through the end of the year the production rate was reduced to 45% of capacity. AFFECTED LANDS Affected lands did not increase significantly except for the areas related to tailing deposition and the McNulty Dump (Area 6 ) . The Mayflower tailing pond crest line was raised approximately 17-1/2 ' , increasing the areal extent of the pond from 335 acres in 1982 to 361 acres at years end. Tailing deposition occurred in the Mayflower pond until mid-October at which time deposition was diverted to the Tenmile pond while Mayflower was utilized as a demonstration water treatment system. Deposition in the Tenmile pond did not increase the area of disturbance in 1985. Open pit waste continued to be deposited on the McNulty Dump during 1985. Approximately eight million tons were added, bringing the total to over 38 million tons. Other disturbances around the mine site totaled approximately seven acres and included haul road widening and maintenance, collector line and associated access road extension, domestic water line construction, construction of tailing line cutouts, and expansion of lateral drain systems.
