currently be forwarded to the BLM on a regular basis and will continue to be throughout <br />the operation of the water treatment plant. <br />The laboratory data provided by Energy Labs and Grand Junction Labs (third parry <br />laboratory) indicate a good degree of correlation between the samples collected to date, <br />especially considering that many of the measurements are in parts per billion. At this <br />time, this data includes a monthly sample collected in December 2007 and a weekly <br />sample collected in January 2008. A monthly third-party sample was also collected in <br />February during the three-day batch treatment and discharge event; however, the <br />laboratory analyses will not be available for three to four weeks due to the long turn- <br />around time for radionuclides. The February analyses will be provided to BLM when it is <br />reported to Energy Fuels. Refer to the attached table for the data that has been received <br />from both Energy Labs and Grand Junction Labs to date. <br />Third Party Lab Data Comparison <br /> 12/19/07 Sam le 1/18/08 Sam le' <br />Parameter Units EL GJL EL GJL <br />C amide m /L <0.005 <0.002 NA NA <br />COD m /L 6 <5 9 <5 <br />g s.u. 7.97 7.1 7.03 6.8 <br />TDS m 2 341 398 NA NA <br />TSS m /L 14 20 20 37 <br />Arsenic Total /L 12 3 5 2 <br />Boron m 2 <0.1 0.05 NA NA <br />Uranium Total /L 160 140 117 100 <br />Be llium Total <1 <1 NA NA <br />Cadmium Total g/L <1 <0.2 <1 <0.2 <br />Trivalent Chromium Total /L <10 <2 NA NA <br />Lead Total /L <10 1 NA NA <br />Man anese Total /L <10 5 32 38 <br />Nickel Total <10 2 NA NA <br />Selenium Total /L 25 26 23 22 <br />Vanadium Total 17 32 NA NA <br />Zinc Total /L <10 10 13 8 <br />Ra-226 Dissolved Ci/L <1 0.2 <1 0.3 <br />Ra-226 Total Ci/L <1 4.7 <1 1.8 <br />Ra-228 Total Ci/L <1 NA 1.7 1.1 <br />EL Energy Labs <br />GJL Grand Junction Labs <br />NA Not Analyzed <br />Notes: <br />1 The 1/18/08 sample was collected during a weekly sampling event and did not require analysis for <br />as many parameters as the 12/19/07 sample, collected during a monthly sampling event. <br />t~,nert.;y l~'t.kcas, incr. ~4 ~Jniccn 131vci., ~iui!t: 6;a~ <br />caao~4.~rs~;r~,g~ii.GCls.cc»ta l,~.l:ew~sacj, C'S~l~3ratiu Sl~22~ <br />
