APPENDIX 13 REVENUE MINE — MINE FACILITY CHANGES FOR TR -01 IN JULY 2013 <br />A) Additional Waste Rock Storage Area <br />The amount of rock blasted from the mill tunnels has necessitated that an additional area of 1.1 acres <br />on the east side of the permit area be used for permanent waste rock storage. It will consist of a flat pad <br />and a sloped area of 3HAV. This area does not drain to Sediment Pond 3 therefore, alternate sediment <br />control of hay bales or equivalent will be used as shown on Maps C -2, C -3 and C -4. The slope will be <br />reclaimed to no steeper than 3HAV and will be covered with 6 inches of topsoil upon reclamation. <br />B) Additional Facilities <br />The mine will also utilize the following structure modifications: <br />1) The office /dry building will be a 2 story structure on a 6" concrete slab as shown on the mine <br />maps. The dimensions are shown on the map. <br />2) The Filter Building outside the mill portal is on a 12" concrete slab and has the dimensions <br />shown on the mine maps. This building will remain after reclamation for storage use. <br />3) 2 potable water tanks are located immediately west of the main mine portal and are used for <br />drinking and shower water in the office /dry building. These tanks are thick plastic 500 gallon <br />tanks that are fed from a small 2" pipe that comes from the mine portal. All of this will be <br />removed for reclamation. <br />
