location will be surveyed and mapped. Exploration will be done using a self-leveling, 10-wheel Davey Drill Truck, which has the capability of driving to each borehole location with minimal disturbance. Drilling will be by air rotary methods, minimizing equipment and materials and resulting in a net disturbed area of less than 350 square foot per borehole. Thus, although many sites will require no reclamation (drilled in existing mine road or drill road and/or in bedrock), a maximum of 2.4 acres could be disturbed. Detailed completion information will be submitted as the holes are completed. Because of the minimal amount of impact of this drilling activity, there is no need to remove any topsoil. All activities will be conducted by carefully accessing the site with minimal disturbance. The exploration borehole area will be reclaimed continuously, as each borehole is completed and the drilling rig moves to the next location. 4. Re-seeding of Disturbed Areas (a) As previously described, exploration drilling and mining will be all on existing disturbances. Minor additional acreage will be disturbed as access roads are widened and ditches cut or berms constructed on uphill side for surface drainage control. Table F-1 _ Pronosed Surface Disturbance. Area Description Previously Disturbed acres Total Disturbed Area acres Parking and staging area 0.92 2.2 Monogram Pit disturbed area 1.5 2.0 Overburden Stockpile 0 0.2 Road improvements for hauling and drilling 2.0 2.8 Exploration borehole sites 2.0 2.4 Estimated acreage disturbed 6.42 9.6 The current surface land owner prefers that the general area be left as is for recreational purposes with reclamation being limited to filling in hazardous or dangerous adits and shafts and erodible roads or trails. Thus, only an additional 3.2 acres will be disturbed and reclamation will be limited to about 6.8 acres. Most of the planned disturbance is reclaimed concurrently such as the sections of the Monogram Mine or individual boreholes and thus costs are ongoing. Assuming that all re-vegetation reclamation was completed at the end of the mining project, costs, including re-contouring the land surface, scarifying, and seeding and mulching (certified weed free hay or straw mulch) is estimated to have a unit cost of about $1100/acre; a total of $7,480.00. Another major aspect of reclamation will be breaking up and removing the ore bins from the staging area. The pad and bin contain about 56 cubic yards of concrete which will cost about $40 per yard to remove and dispose of for an estimated cost of $2,240. Reclamation will be concurrent with the exploration and development efforts and complete within six months of termination of mining efforts. In the event that further underground mining is warranted, a major permit revision will be prepared and include revised reclamation costs and timetables. Monogram Mine - November 2008 E-2
