Page 4 <br /> Miners Mall intends to utilize the 850 square feet(33%)of the 2,580 square foot pre-existing <br /> disturbance as the Main Work Area with operational disturbance <br /> 90%of all material mined will be removed from project site,except for granite/schist waste soil <br /> and rock. Miners Mall proposes that this material be stockpiled within the designated waste rock/ <br /> soil area of 0.02 acre. This material will be replaced into the portal during reclamation. <br /> Approximately 10 feet from the portal,a flat area of less than 0.01 acre (300 square feet)within the <br /> pre-existing disturbance will be utilized for as an additional operation area. <br /> No changes will be made to the exterior of the portal,and it will remain the same at this time, <br /> unless deemed otherwise by the BLM or DRMS. No structures of any sort will be added,with the <br /> exception of safety features deemed necessary.This will keep visual resources from being impacted <br /> in any way. <br /> Access from the parking lot to the Siberia Project Area (Appendix A, Figure 3)will be by foot,totaling <br /> 0.14 acres (300 feet long—2 foot wide)along a previously disturbed single track. Additional access <br /> and cautionary signs will be added to the travel route and an additional security trail camera with be <br /> installed along this route. <br /> This single track will be reclaimed after mining concludes.. . In order to facilitate later vegetation <br /> regrowth, Miners Mall will immediately seed along the edges of the trail with native grass seed. <br /> Final seeding and mulching will be performed on the entire 2,580 square foot trail. <br /> Miners Mall/Humming Bird Mine is currently bonded with BLM/DRMS. The total proposed <br /> increase of disturbance would be approximately 0.06 acre. <br /> 3.4 Description of Operations <br /> Proposed Mining Activities <br /> Mining activities will occur in 3 phases: stabilization, mining the vein,and reclamation. <br /> Phase One consists of assessing the current geotechnical stability and environmental conditions of <br /> the existing portal/adit. Previous operations utilized non-standard mining techniques. Several <br /> holes were drilled into the tunnel from the surface, and large quantities of muriatic acid was poured <br /> into the ground,ostensibly to loosen the non-reactive minerals within the fault.When that failed, <br /> blasting was performed before the DRMS sealed the portal with a steel gate. <br /> Mechanical scaling will be completed to remove decomposed rock from the ceiling and walls of the <br /> mine. Supports,cribbing and reinforcements will be added as needed. <br />
