by the Division. This is likely due to the differences in technology used to create the contours maps. All the
profiles depict a gradual slope with a southern aspect.
The profiles generated for Transect 2 using the Exhibit A map and the Exhibit 18 -1 map are very similar. Like
Transect 1, the original proposed post operation topography is generally lower than the elevations reported in the
SL1 application. Two of the points collected along Transect 2 (stations 6 +10 and 10 +08) depicts a steep elevation
drop and then a quick rise and is not consistent with the other two elevation profiles for these stations. During the
inspection, the Division did not observe these steep drops and rises at these stations. There may have been an
error with the GPS data at these points. Overall the profiles depicted a gradual hill slope with an eastern aspect.
Given the Divisions findings the Operator appears to have graded the area as they have depicted on the SL 1 map.
The post mine topography varies a little from the proposed post mine topography depicted on the Exhibit 18 -1
Map within the permit, however they are very similar. The area has been graded to match the surrounding
topography with a gentle south and east aspect.
