- 23 - <br />• and, very probably, the absence of ground water. <br /> We recommend that the mine management reviews their <br /> mine plans and considers relocation of the proposed waste <br /> disposal pile to some of the recommended locations. We ex- <br /> pect that only two monitoring wells would then be required <br /> for ground water monitoring purposes; we feel that the <br /> probability is high that no ground water will be encountered <br /> above and below the pile. <br /> 7.0 RECOMMENDED FURTHER STUDIES <br /> 7.1 LANDSLIDE EVALUATION <br />• W <br />h <br />Ph <br />d <br />h <br />d <br />i <br />2 <br />k <br /> , a one to two <br />e recommen <br />t <br />at <br />ur <br />ng t <br />e <br />ase <br />wor <br /> days field documentation be made at the location of the land- <br /> slides above the mine area which have been identified by <br /> the Colorado Geological Survey. This field documentation, <br /> together with the study of aerial photographs, should verify <br /> the existence of these landslides and enable evaluation of <br /> whether they have any relation to the existing mine facili- <br /> ties or post reclamation plans. <br /> 7.2 DRILLING AND TEST PITS <br /> We recommend that about 6 exploration borings be drilled <br /> during Phase 2. One of them would be located at the crushing <br /> and screening level fill, close to its crest at the location <br /> where the fill reaches the maximum height. This boring would <br />~ <br />• be drilled through the fill into the bedrock. The boring would <br /> be advanced by augering within the fill with a possibility of <br /> cco-Nroao caaanNC. n+c. <br />
