Certain aspects of the gravity mill will be outside on the <br />surface, while finer crushing elements will be housed underground. The mill relies entirely <br />upon gravimetric methods and does not include any reagent processing process. This <br />amendment also includes the stockpiling of subgrade milled materials underground until they <br />can economically be recovered (then the materials will likely be removed and shipped to the <br />suitable facility, or other). A suitable underground repository for this subgrade material is <br />currently available within the existing Ruby Trust workings that occurs over 100 feet above the <br />groundwater table. This repository is comprised of an historic crosscut that provides suitable <br />area to store the projected amounts of subgrade ore to be mined at the Ruby Trust for next <br />several years. The location of the potential repository will keep subgrade material from <br />significant contact with groundwater. A thorough assessment of the potential hydrologic <br />balance impacts attributable to these proposed amendment activities is provided in EXHIBIT C. <br />This package contains one original and two copies of the following items; <br />a) The standard 'Hard Rock/Metal Mining Limited Impact Operation (110(2)) Reclamation <br />Permit Application Package' <br />b) Exhibits A, B, C, D, E, F,1, J, L and an evaluation of the Geotechnical Stability Exhibit <br />c) a check for Amendment Fees from the Mount Sneffels Mining Company, LLC
