Water Information <br />Exhibit G <br />characterized. Wildcat will use an approved laboratory with <br />written QA/QC procedures. In addition Wildcat will submit duplicate and <br />blank samples twice a year. <br />6.4.7(3) Projected Water Requirements <br />The water balance for the mining and milling is presented in Exhibit G, Table G -1 where <br />water consumption uses include: <br />• Mining /milling process water; <br />• Dust control; and <br />• Augmentation pond evaporative losses (if built). <br />Mining and Milling: The project requirement for milling is estimated to be approximately <br />1 ton of water for every ton of ore milled. This equates to approximately 7 acre feet per <br />year (Table G -1). This represents an average daily use of 6.3 gpm on a 250 work day <br />year. We estimate approximately 75% will be recovered through recycling. The fate of <br />the remainder will be encapsulation during dry tailings disposal activities or used to <br />control underground fugitive dust emissions as summarized in Exhibit D. <br />Dust Control: The estimated volume of water included the consideration of a road length <br />of fourteen thousand one hundred feet (14,100 feet). This equates to an average of <br />approximately 5.27 gpm based on 250 days. The total annual volume of water estimated <br />for dust control is approximately 5.83 acre feet per year (Table G -1). <br />Augmentation Pond: The estimated annual evaporative loss would be 0.6 acre feet per <br />year (Table G -1). <br />No irrigation for reclamation activities is planned and no domestic consumptive use is <br />assumed. <br />The total annual consumptive use is estimated to be 15.26 acre feet (approximately 13.8 <br />gpm on a 250 day basis). <br />6.4.7(4) Projected Water Sources <br />Wildcat has two water rights as documented in Exhibit G, Attachment G -6 (Fairview <br />Land Corporation and Wildcat Mining Corporation). The 1904 senior water right, <br />acquired through the lease with Fairfield Land Company (Attachment G -1, Case No. <br />80CW133), allocates groundwater at a consumptive use rate of 40 gallons per minute <br />(gpm) for the purposes of mining, milling and industrial activities from the May Day <br />Mine. The second water right was filed on November 30, 2006 (Case No. 06CW91) and <br />authorizes the conditional use of 1 cfs (capped at 12 acre feet per year) for mining, <br />Wildcat Mining Corporation <br />May Day Idaho Mine Complex — 112d Permit Application <br />Revised August, 2011 <br />Exhibit G — Rule 6.4.7 <br />Page 5 of 6 <br />
