This is the Quarterly Chloroform Monitoring Report as required under State of Utah Notice of Violation and Groundwater Corrective Action Order State of Utah Department of Environmental Quality UDEQ Docket No UGQ-20-01 for the Quarter of 2009 the Quarter for Denison Mines USA Corp.s DUSAs White Mesa Uranium Mill the Mill This Report also includes the Operations Report for the Long Term Pump Test at MW-4 TW4-19 TW4-15 MW-26 and TW4-20 for the Quarter SAMPLING AND MONITORING PLAN 2.1 Description of Monitor Wells Sampled During the Quarter During the Quarter the following chloroform contaminant investigation groundwater samples and measurements were taken 2.1.1 Groundwater Monitoring Groundwater Monitoring was performed in all of the chloroform monitoring wells being the following wells MW-4 TW4-13 TW4-1 TW4-14 TW4-2 MW-26 TW4-3 TW4-16 TW4-4 MW-32 TW4-5 TW4-18 TW4-6 TW4-19 TW4-7 TW4-20 TW4-8 TW4-21 TW4-9 TW4-22 TW410 TW4-23 TW4-11 TW4-24 TW4-12 TW4-25 The locations of these wells are indicated on the map attached under Tab Wells sampled during this reporting period were analyzed for the following constituents Chloroform Chloromethane Carbon tetrachloride Methylene chloride Chloride Nitrogen Nitrate Nitrite as 2.1.2 Groundwater Head Monitoring Depth to groundwater was taken in the following wells and/or piezometers during the Quarter All of the chloroform contaminant investigation wells listed in paragraph 2.1.1 above in two measurement events on either September 10 2009 The point of compliance monitoring wells under the Mills Groundwater Discharge Permit GWDP on September 10 2009 Piezometers P-i P-2 P-3 P-4 and P-S on September 10 2009 In addition weekly depth to groundwater measurements were taken in MW-4 TW4-15 MW-26 TW4-19 and TW4-20 as part of the long term pumping test for MW-4 2.2 Sampling Methodology Equipment and Decontamination Procedures The sampling methodology equipment and decontamination procedures that were performed for the chloroform contaminant investigation during the Quarter can be summarized as follows 2.2.1 Well Purging and Depth to Groundwater list is gathered of the wells in order of increasing chloroform contamination The order for purging is thus established Mill personnel start purging with all of the non-detect wells and then move to the more contaminated wells in order of chloroform contamination starting with the wells having the lowest chloroform contamination and Before leaving the Mill office the pump and hose are rinsed with de-ionizedDIwaterMillpersonnelthenproceedtothefirstwellwhichisthewell indicating the lowest concentration of chloroform based on the previous quarters sampling results Well depth measurements are taken and the two casing volumes are calculated measurements are made using the same instrument used for the monitoring wells under the Mills GWDP The Grundfos pump gpm pump is then lowered to the bottom of the well and purging is begun At the first well the purge rate is established for the purging event by using calibrated gallon bucket After the evacuation of the first well has been completed the pump is removed from the well and the process is repeated at each well location moving from least contaminated to most contaminated All wells are capped and secured prior to leaving the sampling location 2.2.2 Sampling Following the purging of all chloroform investigation wells the sampling takes place usually the next morning Prior to leaving the Mill office to sample cooler along with blue ice is prepared The trip blank is also gathered at that time the trip blank for these events is provided by the Analytical Laboratory Once Mill Personnel arrive at the well sites labels are filled out for the various samples to be collected All personnel involved with the collection of water and samples are the outfitted with rubber gloves Chloroform investigation samples are collected by means of dedicated bailers and the wells are purged by means of dedicated portable pump Each quarterly pumping and sample collection event begins at the location least affected by chloroform based on the previous quarters sampling event and proceeds by affected concentration to the most affected location The dedicated portable pump is appropriately decontaminated prior to each purging sampling event and the QA rinsate sample is collected after said decontamination but prior to the commencement of the sampling event In response to discussions held with UDEQ on October 29 2009 relative to purging and decontamination of samling equipment mill sampling personnel have been re-instructed as to decontamination procedures in accordance with Section 6.2.5 of the QAP and purging practices Mill personnel use disposable bailer to sample each well The bailer is attached to reel of approximately 150 feet of nylon rope and then lowered into the well After coming into contact with the water the bailer is allowed to sink into the water in order to fill Once full the bailer is reeled up out of the well and the sample bottles are filled as follows First set of VOC vials is filled This set consists of three 40 ml vials provided by the Analytical Laboratory The set is not filtered and is preserved with HCL ii Second 500 ml sample is collected for Nitrates/Nitrites This sample is also not filtered and is preserved with H2504 the bottle for this set is also provided by the Analytical Laboratory iii Third 500 ml sample is collected for Chloride This sample is not filtered and is not preserved and After the samples have been collected for particular well the bailer is disposed of and the samples are placed into the cooler that contains blue ice The well is then recapped and Mill personnel proceed to the next well DUSA completed and transmitted to UDEQ on May 25 2006 revised Quality Assurance Plan QAP for sampling under the Mills GWDP The GWDP QAP was reviewed by UDEQ and has been approved for implementation The QAP provides detailed presentation of procedures utilized for groundwater sampling activities under the GWDP While the water sampling conducted for chloroform investigation purposes has been conformant with the general principles set out in the QAP some of the requirements in the QAP were not fully implemented prior to UDEQs approval for reasons set out in correspondence to UDEQ dated December 2006 Subsequent to the delivery of the December 2006 letter DUSA discussed the issues brought forward in the letter with UDEQ and has received correspondence from UDEQ about those issues In response to UDEQs letter and subsequent discussions with UDEQ DUSA has incorporated changes in chloroform QA procedures in the form of separate document The chloroform QA document describes the differing needs of the chloroform investigation program and is and attachment to the GWDP QAP where QA needs other than those described in the chloroform QA document are addressed 2.3 Field Data Worksheets Attached under Tab are copies of all Field Data Worksheets that were completed during the Quarter for the chloroform contaminant investigation monitoring wells listed in paragraph 2.1.1 above and sampled during the sampling event of September 14 15 2009 2.4 Depth to Groundwater Sheets Attached under Tab are copies of the Depth to Water Sheets for the weekly monitoring of MW-4 TW4-15 MW-26 TW4-19 and TW4-20 as well as the monthly depth to groundwater monitoring data for chloroform contaminant investigation wells measured during the quarter Depth-to-groundwater measurements which were utilized for groundwater contours are included on the Field Data Worksheets at Tab of this report DATA INTERPRETATION 3.1 Interpretation of Groundwater Levels Gradients and Flow Directions 3.1.1 Current Site Groundwater Contour Map The contour map Tab uses the September 10 2009 data for the wells listed in paragraph 2.1.2 above September 10 2009 data for the wells listed in paragraph 2.1.2 and September 10 2009 data for the piezometers and wells listed in paragraph 2.1.2 above Also included under Tab is groundwater contour map of the portion of the Mill site where the four chloroform pumping wells are located with hand-drawn stream tubes in order to demonstrate hydraulic capture from the pumping 3.1.2 Comparison of Current Groundwater Contour Maps to Groundwater Contour Maps for Previous Quarter The groundwater contour maps for the Mill site for the second quarter of 2009 as submitted with the Chloroform Monitoring Report for the second quarter of 2009 are attached under Tab comparison of the water table contour maps for the Quarter to the water table contour maps for the previous quarter indicates similar patterns of drawdown related to pumping of MW-4 MW-26 TW4-15 TW4-19 and TW4-20 Water levels and water level contours for the site have not changed significantly since the last quarter except for few locations Reported decreases in water levels of approximately 12 feet in well MW-20 and of approximately feet in well TW4-3 occurred Reported increases in water levels of approximately 14 feet in pumping well TW4-19 and of approximately 24 feet in pumping well TW4-20 occurred Water level fluctuations at pumping wells MW-4 MW-26 TW4-15 TW4-19 and TW4-20 are due in part to fluctuations in pumping conditions just prior to and at the time the measurements are taken The largest increase decrease in drawdown of approximately 24 feet occurred at TW4-20 The reported water level decreases of approximately 12 feet in MW-20 and of approximately feet in TW4-3 are anomalous considering the previous stability of water levels in these non-pumping wells Furthermore the reported depth to water of 93.21 feet for MW-20 is at or below the bottom of the well casing and the Brushy Basin contact 3.1.3 Hydrographs Attached under Tab are hydrographs showing groundwater elevation in each chloroform contaminant investigation monitor well over time 3.1.4 Depth to Groundwater Measured and Groundwater Elevation Attached under Tab are tables showing depth to groundwater measured and groundwater elevation over time for each of the wells listed in Section 2.1.1 above 3.1.5 Evaluation of the Effectiveness of Hydraulic Capture Perched water containing chloroform has been removed from the subsurface by pumping MW-4 MW-26 TW4-15 TW4-19 and TW4-20 The purpose of the pumping is to reduce total chloroform mass in the perched zone as rapidly as is practical These wells were chosen for pumping because they are located in areas of the perched zone having relatively high permeability and saturated thickness and high concentrations of chloroform were detected at these locations The relatively high transmissivity of the perched zone in the vicinity of the pumping wells results in the wells having relatively high productivity The combination of relatively high productivity and high chloroform concentrations allows high rate of chloroform mass removal The impact of pumping these wells is indicated by the water level contour maps attached under Tabs and Cones of depression have developed in the vicinity of the pumping wells which continue to remove significant quantities of chloroform from the perched zone The water level contour maps indicate that effective capture of water containing high chloroform concentrations in the vicinity of the pumping wells is occurring As noted in Section 3.1.2 increases in water levels decreases in drawdowns occurred at TW4-19 and TW4-20 since the last quarter Overall the combined capture of MW-4 MW-26 TW4-15 TW4-19 and TW4-20 has not changed significantly since the last quarter The decreases in drawdowns at TW4-19 and TW4-20 have decreased the apparent capture zones of these wells relative to that of other nearby pumping wells Although high chloroform concentrations exist at some locations downgradient of the pumping wells for example near TW4-4 the low permeability of the perched zone at these locations would prevent significant rates of chloroform mass removal should these wells be pumped By pumping at the more productive upgradient locations however the rate of downgradient chloroform migration will be diminished because of the reduction in hydraulic gradients and natural attenuation will be more effective 3.2 Interpretation of Analytical Results 3.2.1 Copy of Laboratory Results Included under Tab of this Report are copies of all laboratory analytical results for the groundwater quality samples collected under the chloroform contaminant investigation on September 14 15 2009 along with the laboratory analytical results for trip blank 3.2.2 Electronic Data Files and Format DUSA has provided to the Executive Secretary an electronic copy of all laboratory results for groundwater quality monitoring conducted under the chloroform contaminant investigation during the Quarter in Comma Separated Values CSV copy of the transmittal e-mail is included under Tab 3.2.3 Current Chloroform Isoconcentration Map Included under Tab of this Report is current chloroform isoconcentration map for the Mill site 3.2.4 Data and Graphs Showing Chloroform Concentration Trends Attached under Tab is table summarizing chloroform and nitrate values for each well over time Attached under Tab are graphs showing chloroform concentration trends in each monitor well over time 3.2.5 Analysis of Analytical Results Comparing the analytical results to those of the previous quarter as summarized in the table included under Tab the following observations can be made Chloroform concentrations have increased by more than 20%in the following wells compared to last quarter TW4-6 TW4-15 TW4-19 TW4-20 and TW4- 22 Chloroform concentrations have decreased by more than 20%in TW4-10 compared to last quarter Chloroform concentrations have remained within 20%in the following wells compared to last quarter MW-4 TW4-1 TW4-2 TW4-4 TW4-5 TW4-7 TW4-11 TW4-18 TW4-21 and TW4-24 TW4-3 TW4-8 TW4-9 TW4-12 TW4-13 TW4-14 TW4-16 MW-32 TW4- 17 TW4-23 and TW4-25 remained non-detect In addition since the last quarter the chloroform concentration in pumping well TW4-19 increased from 990 pgIL to 6600 jig/L the concentration in pumping well TW4-20 increased from 6800 pg/L to 13000 tgfL and the concentration in well TW4-22 increased from 730 pgIL to 2300 .tg/L Wells TW4-23 and TW4-25 remained non-detect for chloroform and the concentration in well TW4-24 decreased slightly from 1.5 g/L to 1.4 pg/L TW4-24 located west of TW4-22 and TW4-25 located north of TW4-21 bound the chloroform plume to the west and north Chloroform concentrations in TW4-6 which was the most downgradient temporary perched well prior to installation of temporary well TW4-23 and which remained outside the chloroform plume until the first quarter of 2009 increased from 120 pg/L to 280 jig/L This well likely remained outside the chloroform plume between installation in the second quarter of 2000 and the fourth quarter of 2008 due to combination of slow rates of downgradient chloroform migration in this area due to low permeability conditions and the effects of upgradient chloroform removal by pumping and natural attenuation TW4-23 continues to bound the chloroform plume to the south The slow rate of chloroform migration in the vicinity of TW4-6 is demonstrated by the contrast between the rate of increase in chloroform at this well compared to the rate of increase in the nearest upgradient well TW4-4 Concentrations at TW4-4 increased from non-detect to more than 2200 ig/L within only quarters whereas 16 quarters were required for concentrations in TW4-6 to increase from non-detect to only to the south 3.3 Quality Assurance Evaluation And Data Validation Quality assurance evaluation and data validation procedures in effect at the time of sampling were followed These involve three basic types of evaluations field QC checks Analytical Laboratory checks and checks performed by DUSA personnel as described below 3.3.1 Field OC Checks Field Quality Control samples for the chloroform investigation program consist of field duplicate sample field blank and trip blank These check samples are to be generated for each quarterly sampling episode During the Quarter 2009 duplicates TW4-65 duplicate of TW4-17 and TW4-70 duplicate of TW4-8 DI blank TW4-60 rinsate TW-4-63 and trip blank were collected and analyzed The results of these analyses are included with the routine analyses under Tab 3.3.2 Analytical Laboratory OA/OC Procedures The Analytical Laboratory has provided summary reports of the analytical quality assurance/quality control QA/QC measurements necessary to maintain conformance with NELAC certification and reporting protocol The Analytical Laboratory QA/QC Summary Report including copies of the Mills Chain of Custody and Analytical Request Record forms for the September sampling event are included under Tab 3.3.3 Mill OA Manager Review The Mill QA Manager which for these sampling events was DUSAs Manager of Environmental Affairs performed four types of reviews determination of whether Mill sampling personnel followed Mill sampling procedures review of the results from the Field QC Checks review of analytical reports for holding times and qualifying indicators for the data and review of the Analytical Laboratory QA/QC analysis The results of the QA Managers review are discussed below Adherence to Mill Sampling SOPs On review of adherence by Mill personnel to the sampling procedures summarized in Section 2.2 above the QA Manager concluded that with the exceptions listed below such procedures had been followed Results From Field QC Checks The duplicate samples of TW4-17 indicated relative percent difference within the prescribed standard of 20%for those parameters duplicated However the duplicate of TW4-8 MW-70 fell outside of RPD tolearance at 31.58%Also trace chloroform presence was indicated in the field blank and rinsate samples The rinsate sample also contained trace presence of chloroform During the Quarter 2008 report period it was noted that field blank de-ionized water continued to yield trace volatile organic presence i.e Chloroform This matter was further investigated by the QA manager and corrective measures included confirmation that purchased de-ionized water had in fact been used for the field blank and two sets of purchased de-ionized waters samples were prepared and duplicate sets were sent to each of two contract laboratories Energy Lab and AWAL Both Labs continued to report the presence of low concentration Chloroform in all of the purchased water samples e.g approximately 30 ppb Concurrently these low concentrations of Chloroform were found in 4th Quarter 2009 field blanks as well During the QA review for the preparation of the 4th Quarter Groundwater Report it was discovered that in fact what was purchased is the resin used to treat the water and not the water itself Accordingly samples of pretreated water treated water and the field blanks themselves were planned for analysis in order to further isolate the cause of this low level contaminant source Field blanks were collected during the 2nd Quarter and the matter was discussed at length with onsite laboratory personnel however the samplings for pre and post treatment DI water continue to show trace chloroform concentrations The laboratory and RSO continue to investigate and an update of those findings will be provided in the 4th Quarter Report In response to program improvement needs the QA Manager has initiated documented review of field recorded parameters and their adherence with Quality Assurance Plan requirements with regard to well purging volumes and stability of parameters Accodingly the results of that review are provided in the Table Below Well Location 2x Casings gal Rqd MOal Pumped Amount Sufficient YJN Conductance RPD pH Temp RPD Redox

parameters were not measureed except at well TW4-17 and turbidity was not measured except at TW4-5 TW4-15 TW4-18 4-19 and TW4-24 With regard to 10 decontamination sampling personnel believed that the process of decontaminating prior to each sampling day and proceeding from the least contaminated to most contaminated well was within the QAP guidelines However subsequent to this reporting period and in recent discussions with UDEQ on October 29 2009 it became apparent that the sampling pump must be decontaminated between each sample location in accordance with Section 6.2.5 of the QAP Necessary corrective actions in accordance with Section 10 of the QAP are described in below Identification and definition of the problem The problem identified is the failure to evacuate casing volumes during purging operations failure to measure at least field paramater data sets within 1-10%and failure to measure turbidity in collected samples Assignment of responsibility for investigating the problem The problem is being investigated by the QA Manager Investigation and determination of cause of the problem Sampling personnel believed that the process of decontaminating prior to each sampling day and proceeding from the least contaminated to most contaminated well was within the QAP guidelines However subsequent to this reporting period and in recent discussions with UDEQ on October 29 2009 it became apparent that the sampling pump must be decontaminated between each sample location in accordance with Section 6.2.5 of the QAP Further investigation as to why turbidity was not measured in all wells in ongoing at the time of this writing Determination of conective action to eliminate the problem Sampling personnel have been informed that the procedures outlined in the QAP for well purging with regard to evacuation of casing volumes and at least sets of field parameters within 10%RPD must be adhered to In addition sampling personnel have been informed that non-dedicated sampling equipment must be decontaminated before each sampling event and between each individual sample in accordance with Section 6.2.5 of the QAP Sampling personnel have been informed that turbidity measurements are required for all samples collected Assigning and accepting responsibility for implementing the conective action It will be the responsibility of the RSO and sampling technicians to implement the conective action 11 Implementing the corrective action and evaluating its effectiveness Implementation of the corrective action has occurred by means of the notification cited under item Above Verifying that the corrective action has eliminated the problem Verification that the corrective action has eliminated the problem will occur subsequent to the receipt of sample results for the 4th Quarter sampling event Review of Analytical Laboratory QA/QC Analysis and Analytical Reports The QA Manager reviewed the Analytical Laboratorys QAIQC Summary Reports and made the following conclusions Check samples were analyzed for each method used in analyzing the Chloroform investigation samples These methods were Parameter Method Nitrogen Nitrate Nitrite as E353 .2 Chloroform E624 Carbon tetrachloride E624 Chloromethane E624 Methylene chloride E624 Chloride A4500-CL ii The check samples included at least the following method blank laboratory control spike sample matrix spike and matrix spike duplicate iii All qualifiers if any and the corresponding explanations in the summary reports are reviewed by the QA Manager The only qualifiers reported were for matrix interference in some of the analyzed monitoring location samples however the reporting limit was maintained below the parameter standard in these instances iv The laboratory holding time for all analyses was within chloroform specification and sample temperature was acceptable upon receipt 12 LONG TERM PUMP TEST AT MW-4 TW4-15 MW-26 TW4-19 AND TW4-20 OPERATIONS REPORT 4.1 Introduction As part of the investigation of chloroform contamination at the Mill site IUSA has been conducting Long Term Pump Test on MW-4 TW4-19 TW4-15 MW-26 and TW4- 20 The purpose of the test is to serve as an interim action that will remove significant amount of chloroform-contaminated water while gathering additional data on hydraulic properties in the area of investigation The following information documents the

chloroform pumping wells on the daily inspection form an example of the form of which is attached as Tab Operational Problems 15 No operational problems in the pumping wells were reported during the 3td Quarter 2008 period 4.7 Conditions That May Affect Water Levels in Piezometers No significant amount of water was added to any of the three wildlife diversion ponds during the Quarter 4.8 Chloroform Analysis Monthly chloroform sampling ceased on November 2003 From that time all chloroform contaminant investigation wells were sampled on quarterly basis The sample results are discussed above in Section 3.2 5.0 CONCLUSIONS AND RECOMMENDATIONS The water level contour map for the Quarter indicates that effective capture of water containing high chloroform concentrations in the vicinity of the pumping wells is occurring Between the second and third quarters of 2009 the chloroform concentration in pumping well TW4-19 increased from 990 tg/L to 6600 tgfL the concentration in pumping well TW4-20 increased from 6800 g1L to 13000 jig/L and the concentration in well TW4- 22 increased from 730 pg/L to 2300 g/L Fluctuations in concentrations in these wells are likely related to variations in pumping in TW4-20 and nearby wells and their location near the suspected former office leach field source area Regardless of these measured fluctuations in chloroform concentrations sampling of temporary wells TW4-24 located west of TW4-22 and TW4-25 located north of TW4-21 indicated these wells remain outside the chloroform plume and thus bound the plume to the west and north Chloroform was not detected at TW4-25 and was detected at concentration of 1.4 g/L at TW4-24 The chloroform concentration at downgradient well TW4-6 which remained outside the plume until the first quarter of 2009 increased from 120 to 280 g/L Although fluctuations in concentrations have occurred this well likely remained outside the chloroform plume between installation in the second quarter of 2000 and the fourth quarter of 2008 due to combination of slow rates of downgradient chloroform migration in this area due to low permeability conditions and the effects of upgradient chloroform removal by pumping and natural attenuation Chloroform remained non detect at downgradient temporary well TW4-23 which continues to bound the chloroform plume to the south Continued pumping of MW-4 MW-26 TW4-15 TW4-19 and TW4-20 is recommended Pumping these wells regardless of any short term fluctuations in concentrations detected at the wells such as at TW4-20 helps to reduce downgradient 16 chloroform migration by removing chloroform mass and reducing average hydraulic gradients thereby allowing natural attenuation to be more effective 17 TabA EXPLANATiON perched morrdoOng well
