Response to CN-01 Third Adequacy Issues - June 6, 2011 <br />Response #18 <br />Wildcat Mining has revised the minim plan to remove the 700 foot long pipeline Wildcat <br />Minim has also revised the tailings dewatering design to include a filter press and the <br />creation of dry tailings. The filter press will be located less than 50 feet from the mill <br />discharge point. Slurried tailings from the processing facilities will be conveyed via a dual <br />walled pipeline to the filter press where water will be recycled in dual walled pipe from the <br />filter press back to the processing facility. <br />Dry tailings will be transported to historical underground mine workings identified on <br />Figure D-111. See Attachment C The containment of process solutions containing DRMS <br />designated chemicals is presented in the Environmental Protection Plan (EPP) Exhibit U as <br />required by Rule 6.4.21(7)(e). See Attachment J <br />Adequacy Issue #19 <br />Please clarify the statement appearing on page 3 of Attachment E- 1, Exhibit D, Mining Plan, of <br />the amended application, <br />"Dry stacked tailings disposal or submerged tailings will be implemented at the <br />May Day Idaho mine complex. (See Figure D-1 a for disposal site options. <br />Tailings (150-200 mesh grind) will be dewatered after the material is transported <br />to the approved disposal location. " <br />Specifically, please clarify the apparent definition of "tailings" as being limited to 150-200 mesh <br />size fractions. Please clarify the fate of tailing particles larger than 150 mesh and smaller than <br />200 mesh, if any. <br />Response #19 <br />In response to Adequacy Issue #19, Wildcat Mining states that tailings are processed rock <br />that is crushed and floated. Wildcat Mining anticipates based on its proposed milling <br />operations that tailings will consist mainly of 150-200 mesh size fractions Any material <br />gangue that is not concentrated for further processing, regardless of size, will be dried <br />and disposed underground in the designated disposal area <br />Adequacy Issue #20 <br />On pages 1 and 2 of Attachment E-1, Exhibit D, Mining Plan, and the application identifies three <br />staging areas. One of the staging areas, located adjacent to County Road 124, is shown on the <br />application maps. However, the other two staging areas are not shown on the application maps. <br />Please delineate and label the locations of all staging areas on the application maps. Please <br />identify all staging areas as affected lands in Exhibit A, Legal Description. <br />Revised <br />6/6/2011 <br />18
