Level 6 Waste Rock Removal <br />The Level 6 waste rock contains potentially acid generating materials. Acid is a hazardous substance and <br />is generated when the acid-bearing rock comes in contact with oxygen and water. In order to control acid <br />generation, several approaches can be taken: prohibit oxygen contact with the rock, and/or prohibit water <br />contact with the rock. <br />Currently, the flow pathways by which water contacts the existing Level 6 waste rock pad are unclear. As <br />demonstrated during the April 28, 2008 site visit; it appears that the portal/pad occur between two fault <br />systems that contribute potential flows to the waste rock toe seep. Until this year, the effects (or lack <br />thereof) of Deadman gulch flows to the waste rock toe seep could not be observed. Now that the <br />Deadman gulch geotextile channel is in place, the isolation of these flows from the waste rock enables us <br />to review site conditions and the hydrologic setting. As observed, the toe seep was flowing at <br />approximately 100 gpm. Given the fact that the Deadman gulch flows are isolated and do not contribute <br />to the seep, and that the mine is relatively dry (producing approximately 2-3 gpm underground); there <br />must be another source of flows contributing to this seep. Site observations identify possible fault-related <br />flows along a path to the north of the Level 6 pad. These flows are further identified by the presence of <br />water-dependent aspen tree stands. Further evidence was provided with the measures of pH indicating <br />that the waste rock toe seep (pH of 2.9) is receiving water from an acid generating formation (rhyolite), <br />and not from Deadman Gulch (pH measures of 6.1 - 6.2) or from alluvial formation flows (pH - 5.6). It <br />is not possible for Deadman Gulch or alluvial water pH values to plummet from 6.1 or 5.6 to a value of <br />2.9 in that distance - at that flow rate. These results indicate that there must be another water source that <br />already contains acid generating characteristics. <br />It is absolutely essential that the potential flow paths associated with this setting be clearly understood <br />before the waste rock removal effort be under-taken. It is a pre-conceived notion that removal of the <br />waste rock pile from Deadman Gulch will `correct' the water quality concerns (low pH, mineralized <br />concentrations of metals) associated with the Gulch water. Cursory evidence indicates that the Gulch <br />water is a culmination of combined flows from a diversity of groundwater sources. If the water in this <br />system is fed by naturally enriched groundwater systems, such as those associated with the two faults, it is <br />unlikely that water quality will change as a result of the waste rock removal. Furthermore, the ultimate <br />purpose of the waste rock removal effort is to remove the waste rock from any and all water contact; thus <br />removing the waste rock as an acid generation source material. Therefore we absolutely need to <br />understand and locate any and all water flow pathways before moving the material, and potentially <br />creating another water and waste rock contact scenario. <br />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 />8
