'lhe Dollar elevation of DH 65 was originally established in 1982 at 8306.21 feet. 4he monitoring point established at this site was surveyed in January 1994 at elevation 8306.15. Station DH 66: Drill hole 66 is located between the Lst West Male and the 2nd West Main in the west thick opal pod with approximately 1290 feet of cover. No minim oocurred in the vicinity of Drill hole 66 during 1993. ZY1e collar elevation of DH 66 was originally established in 1982 at 8209.89 feet. the monitoring point established at this site was surveyed in Janua~.y 1994 at elevation 8189.50. An apparent error in survey elevation data exists for this site. Additional data will define current coordinates. Station DH 68: Drill hole 68 is located over Panel Z with approximately 1250 feet of cover. Advancs mining occurred directly under drill hole 68 in October, 1993. 'ihe collar elevation of DH 68 was originally established in 1982 at 8191.92 feet. 'Ihe monitoring point established at this site was surveyed in January 1994 at elevation 8191.53. Station 94: Station 94 was newly established in 1993 and is located at the Grosse-Rhode cabin identified as structure 32 on permit No. C- • 81-038; Map No. 9-7. Advance mining of Panel Y in this vicinity occurred during Dece~nbes, 1993. 'Ibis station overlies approximately 2000 feet of Overburden. 'Ihe monitoring point established at this site was surveyed on December 8, 1993 at elevation 8756.47. Station 95: Station 95 is located at the North quartex~orner of Section 15. 'Ihe elevation of station 95 was defined by satellite survey in July, 1992 as 8415.4 feet. Panel Y development occurred east of Station 95 during July, 1993. Station 95 was resurveyed in January 1994 and showed a 0.75 feet elevation change. It is not apparent whether this elevation change is associated with subsidence or the difference in survey techniques. Cover in the vicinity of Station 95 is approximately 1550 feet and subsidence of this degree would not be anticipated in this area particularly prior to retreat mining operations.
