Personnel Waldo Excavation project activities will be managed by Mr. Kurt Waldo and an additional four employees required to support equipment removal activities. Ball Mill Removal Plan Building-Ball Mill Removal The front of the Quonset mill building (See Figure 2)will be unbolted and removed to expose the mill. Because the mill is mounted on a skid,the mill will be easily moved from the mill building.After mill connections are disconnected,the supported float cells in-side the mill building will be stabilized with steel supports, and the mill will be skidded from the building using the Volvo 250 excavator. No material on the May Day No. 1 bench will be excavated and no other alterations to the building are anticipated. After the mill is removed,the front of the Quonset Building will be replaced, bolted and secured. Steep Road Grades and Turns The access haul road(see Figure 3-black lined travel route) used to remove the mill has a stretch of road where the grades approach thirty percent and hair-pin turns exist.A dozer will be taking the lead to skid and steer the mill around sharp turns and to guide the mill within the approved access haul road right of way.The Volvo 250 excavator will be located upgradient of the dozer and attached to the skid to provide stability,and as necessary,guide the skid within the road right of way No new disturbed areas are proposed, and no new land disturbances are anticipated. Following mill removal activities,and as necessary,the travelled road will be regraded. River Crossing The heavy equipment to move the mill and generator requires the crossing of the La Plata River(See Figure 4a and 4b)The equipment will be transported across the La Plata as outlined in the Army Corp of Engineers letter dated August 20, 2019. (See Attachment C). Wildcat is not required to obtain an Army Corp of Engineers River permits, however an approved TR from the CDRMS is requried.
