John Hamrick and Randy Whicker <br />Cotter Corporation (N.S.L) <br />October 10, 2011 <br />Page 4 <br />4.0 REFERENCES <br />ame0 <br />• The existence of mine pool water as the only potential source, based on this data set, <br />that could produce the observed elevated uranium and TDS concentrations at Sump No. <br />10 by mixing with alluvial groundwater. <br />Additional investigations which could be used to better evaluate the probable source of elevated <br />uranium in the area of Sump No. 10 include (1): Detailed mixing calculations, (2) geochemical <br />modeling to simulate the effects of mixing and aquifer mineralogy on groundwater composition, <br />and (3) uranium isotopic analyses of mine pool and alluvial groundwater. <br />Goldberg, S., H.S.
