• <br />• <br />• <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 />veins. Therefore, deposit thickness is not applicable. <br />(e) Describe the major components of the mining operation such as: <br />roads, access routes, pit, office, shop /maintenance buildings, plant, <br />processing facilities, and any underground openings such as adits or <br />ventilation facilities. These components must be located on Exhibit E <br />— Map: <br />Exhibit E depicts the major components of the existing mining operation. With the exception of <br />the proposed Cross Mine Decline Portal, new office /dry facility, waste rock pile(s) and new <br />sewer system, no other changes are proposed at this time. The proposed office /dry facility will <br />measure approximately 30 feet by 57 feet. The dimensions of the other proposed facility <br />additions will be as depicted on Exhibit E. <br />(f Specify the dimensions of any significant disturbance to the land <br />surface such as pit excavations, mine benches, impoundments, <br />stockpiles, waste rock disposal areas, etc: <br />A new portal and decline to access the underground mine workings is proposed as part of this <br />Amendment. The new portal and decline will be the source of the waste rock. <br />One waste rock pile will be located adjacent the proposed Cross Mine Decline portal. The other <br />waste rock stockpile will be located at the upper or western entrance to the operation. Together, <br />the two waste rock piles will approximately 0.3 acres. The upper waste rock pile will only be <br />utilized in the event there is insufficient room to stockpile the Cross Mine Decline portal waste <br />rock adjacent to portal development. <br />(g) Specify the dimensions of any existing or proposed roads that will be <br />used for the mining operation. Describe any improvements necessary <br />on existing roads and the specifications to be used in the construction <br />of new roads. Describe any associated drainage and runoff conveyance <br />structures to include sufficient information to evaluate structure sizing: <br />No road changes are proposed as part of this Amendment. No changes to drainage and runoff <br />conveyance structures are proposed as part of this Amendment. In the event the upper waste <br />rock pile is needed for waste rock storage, a technical revision will be submitted to address <br />runoff and drainage control, if needed. The existing drainage controls will be sufficient for the <br />proposed waste rock pile adjacent to the Decline portal, new office /dry facility and the new <br />sewer system. <br />Page 26 <br />
