HOMESTAKE PITCH RECLAMATION PROJECT <br />2003 Geotechnical Observations <br />Indian Creek and Tie Camp Creek Waste Rock Dumps <br />I. Indian Creek Waste Rock Dump <br />A. "10800" Level <br />Site Description: Identical to that of past reports for 1996 through 2002. <br />2003 Observations: The 2003 observations are similar to those reported for <br />this area during the past seven years. Usual inspection of the area has <br />revealed no evidence of settling or slumping of the dump material in 2003. <br />Drainage channels are functioning as designed. <br />B. "10780 -10650" Level <br />Site Description: Identical to that of past reports for 1996 through 2002. <br />2003 Observations: The 2003 observations are similar to past observations. <br />Visual inspection of the area has revealed no evidence of settling or slumping <br />of the dump material in 2003. Drainage channels are functioning as designed. <br />C. "10850 -10800" Level <br />Site Description: Identical to that of past reports for 1996 through 2002. <br />2003 Observations: In October 2001 an obstruction was removed from <br />Piezometer IC10600, allowing it to be used for the collection of piezometric <br />surface data. The maximum 2003 water level fluctuation observed in this <br />piezometer was 2.4 feet, which is deemed as an acceptable seasonal <br />variation. <br />D. "10725 -10525" Level <br />Site Description: Identical to that of past reports for 1996 through 2002. The <br />minor overlap between this level and othe_ r bench designations reflects the <br />original bench configuration. <br />2003 Observations: Piezometers IC10600 and IC10525 bound this area. The <br />seasonal maximum water level fluctuation observed in IC10525 was 8.1 feet <br />in a total dump thickness of approximately 229 feet. Data from IC10600 <br />showed a maximum seasonal fluctuation of 2.4 feet. <br />E. "10800 -10400" Level <br />Site Description: Identical to that of past reports for 1996 through 2002. <br />Homestake Pitch Reclamation Project <br />2003 Mnual Geotechnical Report <br />M-1977-004HR <br />2003ReportText <br />
