3. Continued <br />The mining method utilized (know as "resuing" or "stripping") is a time proven method <br />for ore extractian, mini ring the extraction of waste. Waste material will be left as <br />scope fill underground. Any waste removal from the mine workings necessary to <br />accommodate swell, including any waste generated by deveIopmcnt will removed from <br />the mine in the satt~e ruamicr as ore and will be stockpiled in a terraced mine dump azea <br />'t'his material will be inert, boulder Crcc;k or Idaho Springs Granite with little, if any vein <br />material.
