May Day and Idaho Mine Complex 112 (d) Permit Application <br />Mining and Milling: The estimated project requirement for milling is estimated to be <br />approximately 1 ton of water for every ton of ore milled. This equates to a flow rate of <br />approximately 40 gpm, with 30 gpm planned to be recovered through recycling, leaving a total <br />of 10 gpm for milling _The fate of the 10 gpm makeup water will be encapsulated during dry <br />tailings disposal activities or used to control underground fugitive dust emissions. The total <br />estimated annual volume of water required for milling and mining activities is 2.80 acre feet per <br />year. <br />Dust Control: The estimated volume of water included the consideration of a road length of ten <br />thousand two hundred (10, 200) feet. This equates to an estimated volume of 2.5 gallons per <br />minute. The total annual volume of water estimated for dust control is approximately 4.2-1 acre <br />feet per year. <br />No irrigation for reclamation activities is planned. <br />6.4.7(4) Projected Water Sources <br />Wildcat Mining Corporation has two water rights as documented in Attachment G-1 and G-2. <br />The 1904 senior water right, acquired through the lease with Fairfield Land Company, <br />(Attachment G-1, Case No. 80CW133) allocates groundwater at a consumptive use rate of <br />4.2-240 gpm^& +H nn gpm) for the purposes of mining, milling and industrial activities.
