Dept. of .Alatural heso~rces <br />Re: 1980 Annual Report, Henderson Mining Permit ~k77-342 <br />Dear Mr. Ward: <br />Mining and reclamation at the Henderson mine and mill <br />proceeded substantially in accordance with the schedule <br />described in the original application/plan. Our rate of <br />production is presently 30,000 tons of ore per day. Our total <br />work force is 1,895 people. <br />Reclamation proceeded in accord with the timetable (Section <br />5) and the Reclamation Plan (Section 9). Species planted during <br />1979 were those committed to in the approved plan (Section 9). <br />The list submitted in 1978 has not changed. Planting times and <br />locations described in the reclamation plan were followed. <br />Maintenance and establishment fertilizer rates were applie3 in <br />accordance with the plan. In general, materials used in the <br />reclamation effort were 6 tons of 34-0-0 (N-P-K) fertilizer, 9 <br />tons of 20-20-10 (N-P-K) fertilizer, 3,200 shrubs, 3,500 trees, <br />2.5 tons of grass seed, and 15 pounds of shrub seed. Precipi- <br />tation was sparse during the growing season, but vegetation <br />density did not appear to decline. <br />Particularly noteworthy reclamation efforts were assoc=iated <br />with the topsoiling at the Mine Site, dismantling and salv~iging <br />~~ of structures at the Portal Area, topsoiling of a portion cif the <br />tailing dam face, and closing of a small sanitary landfill in <br />the Powerline/Refuse Area. <br />Topsoiling of the mine site slopes was continued with the <br />placement of 2,500 cubic yards. Seed and fertilizer were broad- <br />cast concurrently with the topsoil spreading while seedbed <br />receptivity was optimum. Slopes revegetated in early summer <br />'i were showing grass toward the end of the growing season. :shrub <br />and tree density was increased with the addition of 2,100 rtcore <br />plants in selected locations. Topsoiling efforts will continue <br />in 1981. <br />7 <br />~~ <br />
