During 1995, minor, localized areas of slope instability were noted, con-ected, <br />and reported in the 1995 Mnual Geotechnical Report. <br />2003 Observations: Visual observations indicate that the repairs performed in <br />1995 were successful and no new areas of surficial instability (slips) were <br />observed from 1996 through 2003. Piezometer TC10375 monitors 'the Tie <br />Camp Creek Waste Rock Dump. Water levels are stable at approximately <br />10202.6 feet amsl, with a maximum observed seasonal fluctuation of 6.1 feet <br />during 2003. <br />III. Piezometers - 2003 General Comments <br />The 2003 water level measurements continue to show the normal seasonal <br />variations in the depths to water (and therefore the thickness of the saturated zone <br />at the base of the Waste Rock Dumps). Following the-dry cortdi#ions of 2002, the <br />seasonal variations noted in 2003 were back in line with historic variations. The <br />saturated zone under the dumps remains thin and similar to previous years. <br />Therefore, there continues to be no evidence for stability conoems. <br />Homeatake PRCA Reclamation Protect <br />2003 Mnual Geotechnical Report <br />M-1977-004HR <br />2003RepoRTex1 <br />
