RESPONSE: A portion of Exhibit D within the `Introduction' , the `Reclamation of <br />Existing Geotextile Channel and Eroded Land Slope', as well as the `Level 6 <br />Waste Rock Removal' Section, reflect text changes to address the need for top <br />soil storage. In addition, a new reclamation Figure (Figure B.3) was added to <br />Exhibit D to capture the top soil repository features. <br />Yes, topsoil will be salvaged from those areas that are newly disturbed as a result <br />of anticipated mine activities. These `newly' disturbed settings are small portions <br />of area to the north of the Level 6 and Level 3 pad. Site conditions indicate that <br />top soil is scarce, however a conservative estimate of 2" over these newly <br />disturbed settings was estimated. The anticipated total volume salvaged will be <br />1,675 yd3 from Level 3, and 893 yd3 from Level 6. A small repository will be set <br />aside for each pad area. These repositories were sighted in settings that see little <br />to now stormwater flows and are fairly sheltered due to the artificial topography <br />created by the existing pad setting. The repositories in essence, reside within <br />pocket areas protected from the elements and disturbance. Stormwater controls <br />above and below these repositories will be placed in order to abate any spring <br />melt flows. It is likely that the soils will.p naturally revegetate over the course of <br />time, allowing for additional protection. <br />Item 5: Sixth entry, Page 1. <br />"The application does not include adequate explanation of the reclamation <br />measures to be performed to stabilize the 6 Level cutwall above the portal and <br />borrow area. Please provide this, including earthwork volumes. " <br />RESPONSE: Additional detail was folded into Exhibit D - the Reclamation Plan in the <br />form of additional text, and additional Figures (Figures B.3 and B.5) depicting <br />the anticipated reclamation effort as well as supporting documentation describing <br />how the volume estimate was created (S. Belz/BCH LLC refer to Footnote (a) <br />within the Level 6 Waste Rock reclamation text. A total volume estimate of <br />existing waste rock from the Level 6 waste rock pile was provided (maximum <br />volume of 11,000 cubic yards); along with the methods used to calculate this <br />volume. Since future mine efforts are assumed to remain the same as historic <br />efforts, there currently is no `new volume' to be created by current, ongoing <br />activities. The permit will be amended again, if need be, once details unfold for <br />the mine activities once exploration drilling has been completed (anticipated <br />Spring, 2009). <br />Item 6: Seventh entry, Page 1. <br />"Please provide the earthwork volumes for moving the 6 Level dump material to <br />the north as proposed. " <br />RESPONSE: Please refer to response provided to Item 5 above. <br />Item 7: Eighth entry, Page 1. <br />"Please verify that the proposed seed mix complies with applicable BLM <br />revegetation requirements.
