Permit M-1982-020, Permit Amendment Exhibit C- Mining Plan,Amended ALSH LLC has acquired the Lucky Strike processing facilities and the mine from Aspen Mineral Resources. This acquisition results in the Lucky Strike Mill,as well as the Gold Links Mine,Upper Gold Links,and the Sacramento Tunnel being owned by the same entity, Fossil Creek Mines. With this ownership change we propose to amend the Mining Plan to treat gold and silver ores from the Gold Links Project,that will include ore from Sacramento, Gold Links Mine and the Upper Gold Links permits,in the existing Lucky Strike mill facility. The specific mines that will supply the ores are the Gold Links Mine (permit M- 1987-143),Upper Gold Links Mine (permit M-2016-083), and the Sacramento Access Tunnel (permit M-2016-084). The ore from the Gold Links Mine and the Upper Gold Links Mine are from the"2150 Vein"mined at different elevations. The three permitted mines supplying the ores are in very close proximity to each other. We have performed geochemical analyses of the ores,and have included the reports in the attached supplement to the EPP. Importantly,the ores are similar in that none of them exhibit characteristics of massive sulphides known to possess strong acid- generating potential. The mines named above are nearly 30 miles away,and hauling to the Lucky Strike will be made in covered and sealed trucks designed to eliminate release of solids or ore- affected water. While it is piled and awaiting shipment, ore that is produced at the mines will have had ample opportunity to drain any free water. The ore will be placed on the designated ore storage pad immediately south of the mill facility. The approved Lucky Strike ore storage pad is level and bermed to catch and control any runoff. It is not currently lined,but all stockpiled ore will be removed from the pad and processed within a matter of days,and not stored for extended periods. This greatly reduces the potential for weathering and leaching of contaminants from the ore on an unlined pad. Prompt ore processing is essential,since the Lucky Strike permitted area does not contain sufficient space to allow a large amount to accumulate,nor to remain unprocessed for an extended period of time. The maximum amount of ore to be stored at any one time on the Lucky Strike ore storage pad will be 30 day's production, estimated at 3,000 tons,though often it will be less. This will ensure that ore supplies to the Lucky Strike mill will not be interrupted by adverse winter storms at the mines and mill sites. Ores from the different mines will be stored on the pad in separate stockpiles to enable them to be fed separately into the processing facility to optimize the metallurgical performance. Their total combined tonnage,however,will not exceed the maximum amount stated above. Much of the ore processing to be employed will still be the same; it will consist of crushing,grinding and flotation. ALSH are working with Hazen Research (a world-class metallurgical research laboratory) from Golden, Colorado to optimize the flotation performance with new environmentally-friendly reagents,as the mill is re- commissioned. There will be only flotation circuit-related reagent chemicals used and stored onsite. There will be no leaching or leach chemicals used or kept onsite. The list of reagent chemicals,both dry and liquid,to be stored onsite is shown in the amended EPP. The datasheet information is in a supplement following the EPP.
