ST" -EN ROBERTSON 8 KIRSTEN <br />Homestake Mining Company <br />July 25, 1984 <br />Page -3- <br />system and to produce a containment for runoff during snowmelt or a <br />significant precipitation event prior to removal of the stockpile. <br />10560 to 10450 Levels <br />Generally, these dumps appear to be unchanged from the previous <br />inspection. Some surface sloughing of the dump faces has occurred which is to <br />be expected. <br />10490 Level <br />Some reworking of the dump has been performed in which material was <br />placed over the face of the original dump. Surface cracking at the crest of <br />the dump currently exists due to settlement of this material. Regrading of the <br />surface of this dump to promote drainage off the dump is recommended. <br />10300 Level <br />Placement of the low permeability gouge material at the back of this <br />dump has resulted in a topography which requires regrading to promote <br />drainage. The material is still wet and will be difficult to dress with <br />conventional equipment until dry. <br />Surface cracks at the crest of the dump were observed and are believed <br />to be associated with settlement. Visually, no major movement of the slide <br />mass which moved down the creek during last spring could be detected. Some <br />attempts to develop a 10250 level on the dump face could be seen; however, it <br />was abandoned due to the soft nature of the ground. <br />The base of the 10300 dump at the creek level has been reworked outside <br />of the slide mass which remains too soft to allow access. <br />
