EXHIBIT C Von Doose Mine 110(1)Reclamation Permit Application Mine Plan Introduction At this time, the purpose and scope of this project is exploratory and small scale. It entails driving an 8- foot by 10-foot drift approximately 1,500 feet both parallel and perpendicular to the claim boundaries — starting from a new portal constructed from the surface. While advancing the drift,AMR intends to conduct exploratory drilling and bulk sampling from underground with the objective of identifying small, intermittent pods of silver mineralization. Either simultaneous with advancing the drift, or upon completion of the drift, AMR intends to construct a 500-foot vertical, 8-foot by 8-foot shaft from the drift to the surface for emergency egress and ventilation. There will be 2 separate affected areas on surface to support the proposed operations: 1) the "Lower Affected Area" (LAA) containing the new portal, waste rock dump and laydown pad with a shop building and 2)the"Upper Affected Area"(UAA)containing a boarding house and headframe/shaft house over the escape/ventilation shaft. The elevation and location of the affected areas are purposefully proposed at locations away from surface and groundwater resources. Together the affected areas comprise 4.66 acres. Access The project would be accessed from a private, pre-existing road located on four of RMT's contiguous patented mining claims that are accessed from Ouray County Road 20A (Corkscrew Pass). The private road serves multiple uses such as access for backcountry skiing customers, a soon-to-be constructed sawmill, and general top-to-bottom access to RMT's property for future uses unrelated to mining. Unrelated to this proposal, RMT plans to improve and extend the road during 2019 for improved backcountry skiing access. For these reasons,the majority of the private road is not included in the affected area boundary. The affected areas are proposed along the private road to minimize surface disturbance to RMT's property. Portions of the road adjacent to the proposed operations or that will change due to the operations are included in the affected area boundaries. Lower Affected Area The LAA will contain the new portal, waste rock dump and laydown area and will have an affected area boundary of 3.40 acres. The portal will be constructed in bedrock exposed along a switchback of the existing road. The portal will be reinforced with steel sets (see Attachment C 1) and secured with a steel gate with hooded locks. It will be backfilled as needed depending on ground conditions. The waste rock generated from both the drift and shaft is estimated to total 7,100 cubic yards and will be placed on the perimeter of the existing road for 285 feet. This will result in a 0.45 acre waste rock dump while operations are ongoing. The native slope below the existing road where the dump will be placed is approximately 1.8:1. During operations the slope of the dump will be maintained at the angle of repose which is estimated to be 1:1. Prior to dumping waste rock on the slope below the road,AMR will excavate and salvage 24 inches of topsoil and regolith from the native slope and store in a 300 foot long berm at the Page 1 of 4
