reclamation, once mining ceases. The pile foot prints are estimated not to exceed 0.2 acres. Their <br /> approximate locations are shown on Exhibit E - Maps 6 and 7. <br /> (d) Specify the thickness of the deposit to be mined: <br /> This is an underground mining operation, producing ore from various near vertical mineralized <br /> vems. Therefore, deposit thickness is not applicable. <br /> (e) Describe the major components of the mining operation such as: roads, <br /> access routes, pit,office,shop/maintenance buildings, plant, processing <br /> facilities,and any underground openings such as adits or ventilation <br /> facilities.These components are located on Exhibit E- Map 6: <br /> Exhibit E- Map 6 depicts the major components of the existing mining operation. With the <br /> exception of the proposed Idaho Tunnel rehabilitation, the proposed road, and the increase in <br /> permit boundary, no other changes are proposed at this time. The proposed road will measure <br /> approximately 230 feet in length by 28 feet in width. The increase in acreage to the permit <br /> boundary is 1.03 acres. All proposed facility additions are depicted on Exhibit E- Map 6. <br /> (f) Specify the dimensions of any significant disturbance to the land surface <br /> such as pit excavations, mine benches, impoundments,stockpiles,waste <br /> rock disposal areas, etc: <br /> One waste rock pile will be located adjacent the Cross Ore Building. The other waste rock <br /> stockpile will be located at the upper or western entrance to the Caribou mine. Together, the two <br /> waste rock piles will encompass approximately 0.3 acres.The lower waste rock pile will only be <br /> utilized for waste rock generated from mining development at the Cross mine. The upper waste <br /> rock pile will be utilized for the Caribou Mine and the Idaho Tunnel rehabilitation. <br /> (g) Specify the dimensions of any existing or proposed roads that will be used for <br /> the mining operation. Describe any improvements necessary <br /> on existing roads and the specifications to be used in the construction of <br /> new roads. Describe any associated drainage and runoff conveyance <br /> structures to include sufficient information to evaluate structure sizing: <br /> As described in the Boulder County Development Agreement(dated August 22, 2011), GIR will be <br /> adding an internal property road between the Cross Gold Mine and the Consolidated Caribou Mine. <br /> Dimensions of the road are estimated to be 230 feet in length by 28 feet in width, with an <br /> additional 5 feet of disturbance on both sides of the road. The total area od the road and <br /> disturbance area equals 0.185 acres. (See Exhibit E - Maps 8, 9, 10 and 11). <br />
