Page 4C <br />PROJECT DESCRIPTION ATTACHMENT <br />NOTE: All references to page numbers refer to the photographic "Report on the Santiago Mine" submitted <br />February 12, 2009 for some orientation information. <br />The first 3 years will be limited to the initial work proposed earlier for the mine. This involves mine <br />rehabilitation and clean up and examination of the underground workings. The only potential surface activity <br />will be the reconstruction and restoration of the mill building and dry room once electricity is restored. Full time <br />security will be on site to prevent any further vandalism. Minim and milling methods will be developed once <br />underground conditions are known. Top soil is in place at the 5 Level Portal. (See photo # 19, Page 11 waste <br />rock placement; Drawing, Page 5; photo # 12, Page 10; photo # 16, Page 11.) Drill holes two in number 400 and <br />800 feet on Santiago Ground US Survey #12903 (See Topographical Map.) <br />We do not expect any discharge from the 5`h Level to have any impact on Leavenworth Creek. No water <br />pumped from the mine will flow directly into the Leavenworth Creek drainage, but will be confined to the <br />proposed holding pond. Any water reaching the creek as ground water should be of the same quality or better <br />than that already flowing into Leavenworth Creek from the Waldorf Tunnel, which already supplies a large <br />quantity of water to the creek. It would have to travel through the subsurface for a much greater distance from <br />the holding pond to reach Leavenworth Creek than it presently does to reach the Waldorf Tunnel and then flow <br />into Leavenworth Creek. <br />The calculations for the settling pond submitted to the Colorado Department of Health by Patricia Mosch, <br />mining engineer, are from the Application for Discharge Permit, # CO-0040657 located in Section 3, TSS, <br />R75W in Clear Creek County. (See 7.5 minute topographical map, Page 1; aerial view Santiago Mine Area and <br />relationship to Leavenworth Creek, Page 2; engineer's drawings, Pages 6,7,8; photos 9, 10, 11, page 9. <br />In response to our application for Discharge Permit # CO-0040657 for the Santiago Mine, from the Public <br />Engineer, Permits and Enforcement Section, Water Quality Control Division, the following was stated: <br />"We have reviewed the above referenced {# CO-0040657} application for a NPDES permit and have <br />determined that no such permit is required for this facility at this time. This decision is based upon your <br />indication that no water will be discharged from this operation into State Waters (Leavenworth Creek). From <br />your application form and my subsequent discussion with your consultant, Patricia Mosch, it appears that (using <br />the most conservative estimates) the natural basin on your property to which you will discharge will hold more <br />than twice the maximum probably volume of water to be pumped out of the mine. If you intend to go beyond <br />exploratory activities at the facility or if the operations encounter water in large enough quantities to necessitate <br />discharge, a permit will have to be obtained before the discharge occurs. The NPDES application must be <br />submitted at least 180 days before discharge." Note: The analytical data from the water studies submitted to <br />your office on February 12,2009 was only to demonstrate that we are aware of the baseline from which <br />our work will begin. <br />In addition, continuous monitoring of state sampling data will allow us to see any infraction from the average <br />norm, which exists now that new waters are entering the head waters of Leavenworth Creek northwest of the <br />Waldorf Tunnel discharge point. This will allow any future Santiago water analyses to be segregated data to <br />determine the point of origin of any infraction. <br />Analytical Data <br />Samples will be taken-as soon as available from underground. (Parameters and Appendix A, Appendix B, and <br />Appendix C are attached.)Analytical data for the following parameters, unless exempted, shall be submitted <br />from at least one composite sampling of each discharge point, plus state waters upstream of each discharge.
