M-77-342) <br />Dear Mr. Humphries: <br />Included is the Colorado Division of Minerals and Geology (DMG) Annual 112d-3 <br />Report for Climax Molybdenum Company's Henderson Mine and Mill (Permit No. M- <br />77-342), and our check for the $1,000.00 annual fee. We did not include in this report <br />any updates to our estimated reclamation costs since we are still in the process of working <br />with DMG to refine these numbers. Below is a summary of interim reclamation activities <br />conducted during 2003. <br />Mine Site <br />There were no new disturbances at the Mine in 2003, nor do we expect any in 2004. We <br />conducted no reclamation activities at the Mine in 2003. Additional detail on reclamation <br />completed at the millsite follows. <br />Mill Site <br />The tailing basin water pool increased to an elevation of 8,814.5 feet, which increased our <br />disturbed acreage in azea 9 (Tailing deposition area) in 2003 to 1,037 acres, from 1,026 <br />acres in 2002. Based on past fly-over survey information, Henderson believes this <br />information is conservative. <br />A major reclamation soil project was completed during 2003. The project focused around <br />construction of the infrastructure Henderson will need to efficiently salvage and relocate <br />previously salvaged reclamation soils to long term storage azeas. Approximately 12,000 <br />feet of engineered haul roads were constructed. Haul roads were designed for long term <br />use with large, earthmoving equipment. The project ended with the relocation of 18,000 <br />cubic yards of previously stockpiled soil to the approved long term topsoil storage area to <br />
