<br />1 Memorandum to Christine Johnston <br />October 7, 1999 <br />Page 5 <br />' Healing and sealing of the former cracks is now complete, due to the natural processes of <br />sloughing, erosion, and deposition. <br />' Reexamination of Locations 4, 5, and 6 of September 1998: <br />I • Cracks at Location 4 are no longer visible in northem area of topsoil pile. Healing and <br />sealing is complete. <br />I • New cracks are visible at Location 5 on the berm of drainage ditch. Cracks aze considered <br />to be at least 95 percent attributable to continued mass-gravity movement in the azea that <br />is not related to subsidence processes. <br />I • At Location 6 of September 1998 there aze some fresh cracks as a result of mass-gravity <br />movements that are likely caused by road construction. <br />Location 4. Located neaz the crown of the topsoil pile at approximately the same location as <br />Location 4 of September 1998. <br />1 • On the east part of the pile are two cracks 2 to 4 ft apart and % to 1 inch wide that trend <br />generally N40°W. The cracks aze 30 to 50 ft long and aze 6 to 8 inches deep. The <br />' northern crack curves northward near its termination towards the northwest. The <br />southern crack continues on trend to termination. <br />• On the west side of topsoil pile is a crack 10 to 15 ft long, as much as %:-inch wide and 6 <br />inches deep, that trends N10°W. <br />• These cracks are believed to be the result of settling and mass-gravity spreading of the <br />topsoil pile, and not mining related. <br />' Reexamination of Location 7 of 1998 (Springs G-16 and G-16A): <br />• Spring G-16 is flowing normal for conditions according to Ron Harms. This spring was <br />flowing 2.5 gpm on 5-7-99. <br />' • Spring G-16A, which started flowing in May 1996 and was flowing 1 gpm on 5-7-99, was <br />dry when Ron visited the site 7-8-99. The emergence and decline of this spring may be <br />related completely to nearby construction activities-not mining related. <br />Wright Water Engineers, Inc., 2490 W. 26'" Avenue, Ste. t00A, Denver, CO 60211 <br />Tel. 303480.1700; Faz. 3031480.1020, e-mail:krwright@wrightwater.com <br />
