Box XXX <br />Cedaredge, CO 81434 <br />Dear Sir: <br />This letter is written to notify you of a few issues regarding the <br />reclaimed Red Canyon Mine. Grand Mesa Coal Company mined the property <br />from 1979 through 1965. Most of the mining was performed prior to 1982. <br />The mine was sealed in 1985 and reclaimed in 1988. The mine portals were <br />located in the N/2SW/4SW/4 of Section 12. The mine workings are located <br />in the following areas: <br />Townshio 13 South, Range 95 West, 6th P.M. <br />Section 11: SE/4NE/4, SW/4NE/4, SE/4NW/4, NE/4NW/4 <br />Section 12: N/2SW/9SW/9, NW/4SW/4, SW/4NW/4 <br />The mine workings were developed using four to seven entry systems. The <br />width of the mine workings range from about 200 to 500 feet. Only about <br />508 of the coal was extracted. Adequate coal pillars were left in place <br />to support the surface. Subsidence surveys were performed in 1982, 1985, <br />1986 and 1989. No movement of the surface was detected by the subsidence <br />surveys. There is a remote possibility that subsidence could occur in <br />the areas mined defined above, and in the following surrounding areas: <br />Township 13 South, Range 95 West, 63y .M. <br />Section 11: S/2NE/4NE/4, S/2'fi E/2NW/4NW/4, <br />E/2SW/4NW/4, E/ •. <br />Section 12: S/2NW/4NW/4 <br />The state permit for the coal mine will <br />after reclamation was performed or <br />achieved.
