Request 59b How were Eymundson Sinkholes simulated in the groundwater conceptual
model?
Response 59b The Eymundson Sinkholes were not explicitly represented in the groundwater
models developed for the project because the groundwater flow patterns in the
Quaternary deposits were observed to reflect topographical control. Further, the
sinkholes water level was near the crest of the sinkholes which is in general
agreement with the inferred groundwater elevations of shallow Quaternary
deposits.
Question No. 60
Request Environmental Setting Report, Hydrogeology, Figures, Figure 29.
Shell illustrates “various cross-sections (G-G’, H-H’, and E-E’).”
60a How were these cross-sections developed (sources of information, and
interpolation method)?
Response 60a The cross-sections were developed with the stratigraphic information interpreted
from boreholes drilled for the hydrogeology environmental setting investigation
for the Pierre River Mine (WorleyParsons Komex 2007) and from coreholes
drilled by Shell.
