Whirlwind Decline <br />WHIRLWIND MINE, PERMIT NO. M- 2007 -044 <br />FIRST QUARTER 2013 HYDROLOGICAL REPORT <br />(1) From First Quarter 2008 to Fourth Quarte 2009, the inflow rate was estimated over the quarter by calculating the volume of water pumped out of the mine and treated <br />and estimations of the volume of water evaporated off the untreated water tank and brought out of the mine as moisture in waste rock, ore, and ventilated air. As of the First <br />Quarter 2010, water inflow is estimated based on the approximate water elevation and the void volume of the mine workings. <br />Attachment 3.
