ALBERT FRET & SONS March 10, 2008 Mr. Tony Waldron Division of Reclamation, Mining & Safety Minerals Section 1313 Sherman Street Suite 215 Denver, Colorado 80203-2273 Dear Mr. Waldron: Re: Annual Report, Worthing Pit M.L.R.B. Permit No. M-77-526 P.O. BOX 700 HENDERSON, CO 80640 (303)289-1837 (303) 289-2865 FAX ~~~~~ ''MAR 12 2008 j/®ivlaion viand Safety n Mining Our files indicate that the anniversary date for this permit is March 28, 2008. The effective date of all information in this report is March 7, 2008. Please refer to the attached Annual Report Map for the location of areas discussed in this report. This pit HAS NOT been granted a Temporary Cessation and it HAS operated more than 180 days this year. This permit was amended in 2006 to add construction of a slurry wall to the permit and the current bond is $494,300.00. We will deal specifically with each of the Annual Report requirements as outlined in Rule 1.15 of the Rules and Regulations. (1) Mining ended in the southern area this year, approximately 18.81 acres was mined south of the Plant Site. We continued to remove material stockpiled in previous years and mine material from the bottom of the northern lake areas. The northeast lake has been dewatered and mining began in the spring of 2007 on gravel that remains in the bottom of the lake areas. (2) Backfilling has begun on the southern mined area and eventually the entire 18.81 acres will be backfilled. Since most of the mining area is dewatered the lake now covers 32.84 acres ± of the disturbed area. The tailings area is still being used, but when mining ends it will be silted in and reclaimed. (3) We will continue to mine in the northeast lake area. LaFarge may begin to mine the very south end where the slurry wall was installed. (4) We will continue to reclaim areas where mining has ended. Backfilling will continue in the south lake area. Reclamation will begin in the northeast lake area perimeter slopes as mining progresses. Reclamation preformed to date has been successful.
