Dear Russ:
Attached is the Third Quarter 2008 report for the Whirlwind Mine. Water samples were
collected from the Whirlwind Mine sump and the PR Spring tank pipe on September 8,
2008. DP Spring was checked and a flow measurement was recorded. The nitrate and
nitrite samples were recollected on September 18, 2008 due to hold time exceedance
'issues with the original samples. The laboratory data reports for the two samples are
attached. Photographs of the sampling locations are provided with this letter.
The flows at PR Spring and DP Spring were estimated by determining the time required
to fill a 5-gallon bucket. The estimated flow rates are consistent with historical records
for these springs. The inflow within the Whirlwind decline could not be measured
directly because it occurs over approximately 100 feet of the decline. The Whirlwind
inflow is estimated based on the volume of water treated and estimations of the volume
of water evaporated off the untreated water tank and brought out of the mine in waste
rock, ore and ventilated air. The estimated inflow values for the 1St and 2nd Quarters of
2008 have been adjusted to reflect this method of calculation.
The analytical data for PR Spring and the Whirlwind Mine sump were added to Tables 1
and 2, respectively, which also show previously collected data for comparison purposes.
Please note that uranium activity levels were previously reported incorrectly on the First
and Second Quarter tables for the samples due to a conversion error. These errors have
been corrected on this version of the table. The water sample from PR Spring (see Table
1) was similar in chemistry and water quality to previous sampling events. The sample
from the mine sump (see Table 2) contained lower levels of total suspended solids (26
mg/L) and higher levels of uranium and radium-226. The improvement in total
suspended solids is attributed to the rehabilitation of the mine sump, which was
