To-date, LKA Int./Richmont Mines Inc. have completed a significant amount of effort to evaluate the <br />hydrologic setting associated with the Level 6 pad. The results of several sampling events remain <br />pending, however it is anticipated that a `Hydrologic Evaluation' document will be provided for BLM, <br />DRMS review in Fall, 2008. Concurrent with the hydrologic evaluation, Black Creek Hydrology <br />associates has obtained 3-dimensional survey points to be able to estimate waste rock volumes, storage <br />capacity volumes etc.. The results of these efforts were incorporated into this reclamation plan. <br />Regardless of the unknown status of the Level 6 pad hydrologic setting, this reclamation plan <br />encompasses a waste rock removal effort which would move waste rock currently residing within the <br />Deadman Gulch natural flow pathway, towards the north (thus occupying a portion of the pad, access <br />road and natural hill slopes). In essence, the material would be rolled-back towards the north to fill in the <br />cut slope created by the pad and road. This approach relies on certain site aspect assumptions as follows; <br />The area to the north of the waste rock pile is largely comprised of alluvium and contains no <br />surface expression of rhyollite (the acid bearing formation associated with Gold Hill) (samples of <br />this material have been collected and analyzed - results were provided in Attachment A, Table <br />A.2). Thus, the placement of the Level 6 waste rock to the north, would put the material on top of <br />a geologic formation found to contain a natural buffering capacity. <br />• It was assumed that there are no groundwater flow pathways that would contact the moved <br />material. This assumption was based upon historic observations which indicate that there are no <br />surface expression seeps along the north side of the exposed portal face, pad or access road. <br />Based on surveyed information, the volume of material to be moved from the estimated native <br />Deadman Gulch channel would range from 9,000 -11,000 cubic yards of material. Very <br />conservative assumptions were folded into this volume estimate (Black-Creek Hydrology <br />sociates Refer to Footnote a below for a description-of how the volume of waste rock was <br />---- --- -- - --- -- <br />tunated using survey information: <br />'guts!

Figure B.4 <br />hows the estimated excavation depth to remove the portion of the waste rock pile that occupies the Gulch <br />tive channel.
