These <br />individual areas are limited to less than 5.0 acres and are anticipated to be operational <br />during the life of the mine <br />6.4.4(e) An approximate timetable to describe the mining operation <br />The mine plan has been outlined in the approximate order of operation. The approximate <br />timeline based on a 10 -year mine life: <br />The size and location of each area to be worked in each phase is described above in the <br />detailed phase discussions. <br />6.4.4(f) Description of Ore Body and Underlying Stratum <br />Three types of mineralization are distinguished in the permit area: <br />• highly disseminated epithermal gold - silver - telluride thin veins (typically less than <br />five (5) feet); <br />• limestone replacement deposits; and, <br />• disseminated mineralization in porphyry veins. <br />Initial mining will occur within the limestone replacement deposits associated with the <br />May Day Veins at the May Day No. 1 adit. These veins are found within following <br />Upper Jurassic units: <br />• lower part of the Morrison Formation; <br />• Junction Creek Sandstone; <br />Wildcat Mining Corporation <br />May Day Idaho Mine Complex — 112d Permit Application <br />Revised August, 2011 <br />Exhibit D — Rule 6.4.4 <br />Page 9 of 10 <br />
