DRMS needs the following additional <br />information before we can provide a decision on the NOI: <br />1) Adequacy review #4 requested that the applicant provide a geologic map of the mine and <br />surrounding areas that shows all geologic and lithologic units and all possible geologic structures <br />that could act either as conduits or barriers to ground water flow. Please provide the requested <br />map. <br />2) Adequacy review #4 requested a map or maps that show to the satisfaction of the Division the <br />presence or lack of interconnection with workings of other mines outside the surface footprint of <br />the NOI area of work. On the map of the mine workings provided in your response of October <br />12, a drift (tunnel) is shown that leads in a northwesterly direction away from the Freighter's <br />Shaft and is open-ended, suggesting connection with additional underground workings off site. <br />Please describe the underground workings that are located in that direction, and please plot on a <br />USGS topographical map or equivalent describing or identifying any connections to surface <br />openings and provide description of the conditions of the opening(s), e.g., intact, collapsed, <br />sealed, etc. <br />3) Applicant has proposed the installation of removable shaft covers before commencement of <br />prospecting activities to avoid the necessity of posting financial warranty for shaft safeguarding. <br />Applicant must provide verification that these structures have been installed to the approval of <br />the Division, not merely a commitment that they will be, before the NOI can be approved. <br />Applicant should refer to the document "General Bid Specifications" for guidelines on how to <br />install shaft covers that can be used for temporary access and later converted to permanent <br />covers.
