mean sea level; about 4.5 feet lower than the preceding year, with a seasonal fluctuation <br />of approximately 6.9 feet. The maximum water level for 2002 was below that of <br />preceding years. The total depth of this piezometer is 260 feet and the thickness of the <br />dump is on the order of 240 feet. <br />Piezometer IC10370 is also located in this azea. Water levels in this piezometer have also <br />stabilized at about 10189.9 feet above mean sea level with a seasonal fluctuation of 0.6 <br />feet for 2002. The bottom of this hole is at 1088.5 feet amsl. <br />During 1997, Homestake reconstructed the face of the permanent low-grade ore stockpile located <br />on the Indian Creek Waste Rock Dump. The purpose of the slope reconstruction was to reduce <br />the potential for infiltration and promote more rapid runoff from the slope. No seepage was <br />observed in this area in 2002. <br />G. "10300 -10100" Level <br />Site Description: The Indian Creek Waste Rock Dump was regraded in 1994 following <br />procedures approved in the February, 1994 Technical Revision. During 1995 several <br />minor, localized areas of slope instability were noted, corrected, and reported in the 1995 <br />Annual Geotechnical Report. Visual observations indicate that the repars performed in <br />1995 are successful and no new areas of surficial instability (slips) were observed from <br />1996 through 2002. <br />2002 Observations: The 2002 observations are similar to those reported for past years. <br />Piezometer IC10300 is located in this area. Water levels have continued to show a <br />gradual decline, with the average water level being 10106.4 feet amsl (3.7 feet lower than <br />the previous year) in 2002, and only a minor seasonal fluctuation of 1.4 feet. <br />II. Tie Camo Waste Rock Dnma <br />A. "10400 -10100" Levels <br />Site Description: The Tie Camp Waste Rock Dump was regraded in 1994 <br />following procedures approved in the February, 1994 Technical Revision. Visual <br />observations indicate that the repairs to the minor areas of slope instability <br />(surficial "slips") that were performed in 1995 were successful and no new areas <br />of surficial instability were observed from 1996 through 2002. <br />2002 Observations: The 2002 observations are similaz to those provided in past <br />reports. Piezometer TC 10375 monitors the Tie Camp Creek Waste Rock Dump. <br />The water levels are stable at approximately 10200.8 feet amsl, with a seasonal <br />fluctuation of 1.0 foot for 2002. <br />III. Piezometers - 2002 General Comments <br />The 2002 water level measurements continue to show the normal seasonal variations in <br />the depths to water (and therefore the thickness of the saturated zone at the base of the <br />Waste Rock Dumps), although with reduced amplitude for 2002, probably reflecting the <br />extremely dry nature of the yeaz. The saturated zone under the dumps remains thin and <br />similar to past years. Therefore, there continues to be no evidence of concerns with <br />stability. <br />
