August 15,2013 C-1981-010/Trapper Mine JLE same general shape and slope. The measured elevations were about 3.6 feet higher than the elevations interpolated from the SL14 bond release map. This parcel appears to have been graded in accordance with the approved post mine topography. Parcel A-B-09 was evaluated with Transect 5. This parcel has a north northeast aspect and blends in well with the surrounding topography. The overall slope of this parcel was 28%. The cross-sections of this parcel a very similar in slope and shape. The measured elevations was found to be on average 9.25 feet lower than the elevations interpolated from the SL14 bond release map. This parcel appears to have been graded in accordance with the approved post mine topography. Parcel K-A-10 is located on the lower half of the Horse Gulch Fill. The aspect of the face of the fill is west and the slope was about 30%. The maximum allowable slope of the fill cannot exceed a 3:1 horizontal to vertical ratio. The cross-sections of this transect have the same shape and slope. The measured elevations were found to be 1.43 feet lower than the elevations interpolated from the SL14 bond release map. This parcel appears to have been graded in accordance with the approved post mine topography. Parcel Z-A-10 is broken up into three small parcels. Transects 7, 8 and 9 were used to evaluate each of these parcels. These transects seemed to have the most variability in elevations and slopes when comparing the approved PMT elevations,the SL14 Bond Release Map elevations and the on the ground elevations. On average the measured elevations were about 23.6 feet lower than the elevations interpolated from the SL14 bond release map. Given the small sizes of the parcels,it was very difficult to accurately interpolate the elevations of each of the sample points along these transects given the level of detail of the contour lines on these topographic maps. Given this,it is unlikely the cross-sections for these transects adequately depict the shape and slope of these transects. However;when these maps are overlaid,the general slope and aspect of these parcels depicted on the SL14 bond release map appear to correspond and comply with the approved post mine topography. Visually, these parcels appear to be adequately depicted on the SL14 bond release map and the blend in well with the surrounding topography. This parcel appears to have been graded in accordance with the approved post mine topography. A small portion of Parcel F-A-12 was evaluated during this inspection. Transect 10 runs through this parcel. This parcel has a north northwest aspect with an overall slope of 10%. The parcel blends in with the surrounding topography. The cross-sections of this tansect have the same general shape and slope. The measured elevations were about 7.71 feet lower on average than the elevations interpolated from the SL 14 bond release map. This parcel appears to have been graded in accordance with the approved post mine topography. A portion of Parcel F-A-12 is a long corridor from the east end of F Pit to the west end of F pit. This corridor was used as a road to access two topsoil stockpiles that were located on the west end of F Pit.The road corridor and the topsoil stockpile areas are portions of parcel F-A-12 and were evaluated for compliance with the approved post mine topography during previous inspections. The topsoil was hauled to the east side of F Pit and replaced on graded areas. Once this operation was completed,the topsoil stockpiles and a road corridor were graded to blend in with the surrounding topography. These parcels appeared stable with only minor rilling observed.
