the Energy Fuels Resources (USA) Inc. ("EFRI") White Mesa Mill (the "Mill"), as required under Part I.F.9 of the Mill's State of Utah Groundwater Discharge Permit No. UGW370004 (the "Permit") and Section 6.0 of the Mill's Sampling and Analysis Plan for The Tailings Management System, Leak Detection Systems and Slimes Drains, Revision: 3.0, dated July 8, 2016 (the "Sampling Plan") and approved by the State of Utah Division of Waste Management and Radiation Control ("DWMRC") on August 8, 2016. Cell solution and slimes drain sampling is required under the Sampling Plan and Part I.E.10 of the Permit to be conducted on an annual basis in August of each year for the solutions in Cells 1, 3, 4A, and 4B, the solutions in the slimes drains in Cells 2, 3, 4A, and 4B (for Cells 3, 4A and 4B after the commencement of dewatering), the solutions in the leak detection system ("LDS") in Cell 4A and 4B and any detected solutions in the LDS in Cells 1, 2, and 3 at the time of the August Sampling event. The results of the sampling event are required to be reported to the DWMRC with the Mill's Third Quarter Groundwater Monitoring Report due December 1, of each year. 2.0 SUMMARY OF MILL TAILINGS SYSTEM ACTIVITIES IN 2019 This section provides a brief description of the Mill's tailings management system, and any changes that were made as a result of Mill activities during the reporting year. A description of which systems were sampled is provided in Section 3.0. The Mill is designed not to discharge to groundwater or surface waters. Instead, the Mill tailings system utilizes tailings and evaporation cells for disposal, evaporation, and management of Mill tailings, effluents, and other wastes as indicated below: • Cell 1: dedicated to evaporation of Mill waste solutions~ • Cell 2: contains Mill tailings and has been closed to tailings disposal since 1995 and 1 le.(2) byproduct materials since 2000. Cell 2 Phase 1 cover placement commenced in April 2016; • Cell 3: contains Mill tailings and is in the final stages of filling. It also accepts other Mill wastes and 1 le.(2) material from in-situ recovery ("JSR") operations; • Cell 4A: receives Mill tailings and is used for evaporation of Mill solutions; and • Cell 4B: is used for evaporation of Mill solutions. 1 2.1 Cell 1 Cell 1 is a 55-acre impoundment built in June of 1981. It operates as an evaporation pond which receives solutions only. Cell 1 is equipped with a LDS. In 2019, Cell 1 received fluid from the Mill process, storm water run-off, and Mill laboratory waste. The LDS in Cell 1 was dry in 2019. 2.2 Cell 2 Cell 2 is a 67-acre impoundment built in May of 1980. Cell 2 contains Mill tailings and has been closed to tailings disposal since 1995 and 1 le.(2) byproduct materials since 2000. Cell 2 Phase 1 cover placement commenced in April 2016. Cell 2 is equipped with a LDS and a slimes drain. The LDS was dry in 2019. As part of closure activities, EFRI began monitoring the slimes drain system in 2008. The fluid from the slimes drain is pumped to Cell 4A. Cell 2 no longer receives any solutions or solids. 2.3 Cell 3 Cell 3 is a 71-acre impoundment built in September 1982. Cell 3 is nearly full of solids and is undergoing pre-closure steps. This cell is equipped with a LDS and a slimes drain. The LDS was dry in 2019 and the slimes drain system will be monitored once dewatering begins. In 2019, Cell 3 received solid Mill waste and solid 1 le.2 byproduct material from in situ recovery ("ISR") facilities. 2.4 Cell 4A Cell 4A is a 40-acre impoundment built in 2008. This cell is equipped with a LDS and a slimes drain. The slimes drain system will be monitored once dewatering begins. The LDS in Cell 4A was sampled in 2019, as described below. In 2019, Cell 4A received solutions from the Mill process, and solid tailings sands. 2.5 Cell 4B Cell 4B is a 40-acre impoundment built in 2011. It operates as an evaporation pond which receives solutions only. Cell 4B is equipped with a LDS. In 2019, Cell 4B received fluid from the Mill process. The LDS in Cell 4B was sampled in 2019, as described below. 3.0 SAMPLING EVENTS AND SAMPLING METHODOLOGY 3.1 Sampling Events Samples of solutions from Cells 1, 3, 4A, and 4B, the Cell 2 slimes drain and the Cell 4A and Cell 4B LDSs were collected on August 21, 2019. 2 In accordance with the Permit, OWMRC was notified of the sampling event, and a OWMRC representative was present for a part of the sampling. The OWMRC representative collected split sample aliquots. Maps showing the locations of the solution and slimes drain and, when applicable, LOS sampling locations are attached under Tab B. Table 1, included in the Tables Tab, provides an overview of all solution monitoring samples collected during the current period and includes the sampling date, laboratory report date, and the work order/lab set ID associated with the analytical data. The Permit requires that the samples be analyzed for the water quality parameters listed in Table 2 of the Permit and SVOCs. Additionally, in order to further characterize the radiological constituents and physical properties of the solution, EFRI conducted voluntary analyses on the August 21, 2019 samples for radium- 226, thorium-228, thorium-230, thorium-232, uranium-233/234, uranium-235/236, uranium-238, and specific gravity. The additional data from the August 21, 2019 sampling event are included in separate data tables in Tab 0. The gross alpha results have been evaluated and are included as required. These additional data are included in this rep01t for informational purposes only. EFRI may or may not choose to continue these analyses in future sampling events. 3.2 Field Data Attached under Tab A are copies of all of the field data sheets recorded in association with the annual tailings system monitoring program. Sampling dates are listed in Table 1. 3.3 Sampling Methodology, Equipment and Decontamination Procedures As noted in the OWMRC-approved Sampling Plan, Revision 3.0, dated July 8, 2016, field filtering and preservation of metals and gross alpha sample aliquots was not completed due to safety concerns associated with the filtering apparatus and the backpressure created by the increased viscosity of these samples. The gross alpha and metals aliquots were filtered and preserved as necessary by the analytical laboratory. It is important to note that field preservation of the samples is to preclude biological growth and prevent the inorganic analytes from precipitating. Based on past field data, the cell solutions and LOS and slimes drain samples are at a pH of 3.88 or less at the time of collection without additional preservative. The addition of acidic preservatives in the field would add minimal if any protection from biological growth or precipitation. The VOC sample aliquots were preserved in the field. 3.3.1 Cells Cell solution samples were collected at the cell sampling stations shown on the Figures in Tab B using approved procedures described in the OWMRC-approved Sampling Plan, Section 3.1.2. 3 Disposable or dedicated sampling equipment was used during this sampling event and, as such, rinsate samples were not required. 3.3.2 Cell 2 Slimes Drain Once a tailings cell has started the dewatering procedures, a sample will be collected from the slimes drain system. At this time Cell 2 is the only slimes drain that requires sampling. The location of the slimes drain for Cell 2 is shown in Tab B. While Cells 3, 4A and 4B are equipped with slimes drain sample locations, Cells 3 and 4A are still active and Cell 4B is being used as an evaporation pond, and the slimes drains will not be pumped (and/or sampled) until dewatering operations have commenced. The Cell 2 slimes drain, shown on the Figures in Tab B, was sampled using a disposable bailer as noted in the DWMRC-approved Sampling Plan, Section 3.1.3. Due to the use of a disposable bailer, a rinsate sample was not required. 3.3.3 Cell 4A Leak Detection Systems The Cell 4A LDS sample was collected from the sampling station shown on the Figures in Tab B using a dedicated stainless steel bucket and ladle as noted in the DWMRC-approved Sampling Plan, Section 3.2.2. 3.3.4 Cell 4B Leak Detection Systems The Cell 4B LDS sample was collected from the sampling station shown on the Figures in Tab B using a dedicated stainless steel bucket and ladle as noted in the DWMRC-approved Sampling Plan, Section 3.2.2. 3.3.5 Cells 1, 2, 3, The Cells 1, 2, 3 LDSs were not sampled during the 2019 sampling event because the systems were dry. 3.4 Field QC Samples The field Quality Control ("QC") samples generated during this sampling event included one duplicate and one trip blank per shipment to each laboratory which received samples for VOCs. The duplicate sample (Cell 65) was submitted blind to the analytical laboratory. As previously stated, no rinsate blanks were collected during this sampling event as only dedicated or disposable equipment was used for sample collection. 4 3.5 Laboratory Results All analytical results were provided by one of the Mill's two contract analytical laboratories, GEL Laboratories ("GEL") or Energy Laboratories ("EL"). The laboratories utilized during this investigation were certified under the Environmental Lab Certification Program administered by the UDEQ Bureau of Lab Improvement for the analyses they completed. The analytical data as well as the laboratory Quality Assurance ("QA")/QC summaries are included under Tab C. 4.0 QUALITY ASSURANCE AND DATA EVALUATION The Permit requires that the annual tailings system wastewater sampling program be conducted in compliance with the requirements specified in the Mill's approved White Mesa Uranium Mill Groundwater Monitoring Quality Assurance Plan ("QAP"), the approved Sampling Plan and the Permit itself. To meet these requirements, the data validation completed for the tailings system wastewater sampling program and discussed in this Section utilized the requirements outlined in the QAP, the Permit and the approved Sampling Plan as necessary. The Mill Quality Assurance Manager ("QAM") performed a QA/QC review to confirm compliance of the monitoring program with the requirements of the Permit, the QAP, and the Sampling Plan. As required, data QA includes preparation and analysis of QC samples in the field, review of field procedures, an analyte completeness review, and quality control review of laboratory data methods and data. Identification of field QC samples that were collected and analyzed is provided in Section 3.4 and 4.3.1. Discussion of adherence to the Sampling Plan is provided in Section 4.1. Analytical completeness review results are provided in Section 4.2. The steps and tests applied to check laboratory data QA/QC are discussed in Section 4.3. The analytical laboratories have provided summary reports of the analytical QA/QC measurements necessary to maintain conformance with National Environmental Laboratory Accreditation Conference ("NELAC") certification and reporting protocol. The analytical laboratory QA/QC Summary Reports, including copies of the Chain of Custody forms for each set of Analytical Results, follow the analytical results under Tab C. Results of review of the laboratory QA/QC information are provided under Tab E and discussed in Section 4.3, below. 4.1 Adherence to Sampling Plan and Permit Requirements On a review of adherence by Mill personnel to the QA/QC requirements, the QAM observed that QA/QC requirements established in the Permit, the QAP, and the Sampling Plan were met, as discussed below. 5 4.2 Analyte Completeness Review All analyses required by the Permit Table 2 were completed. In addition, all cell solution samples were analyzed for SVOCs as required by the Permit. It is important to note that the laboratories reported more VOC analytes and SVOC analytes than are required. The data are included in the data packages included in Tab C. The extra data are included as required by the GWDP Part H.F. 4.3 Data Validation The QAP and the Permit identify the data validation steps and data quality control checks required for the tailings system wastewater monitoring program. Consistent with these requirements, the QAM performed the following evaluations: a field data QA/QC evaluation, a receipt temperature check, a holding time check, an analytical method check, a reporting limit check, a trip blank check, a QA/QC evaluation of sample duplicates, a gross alpha counting error evaluation and a review of each laboratory's reported QA/QC information. Each evaluation is discussed in the following sections. Data check tables indicating the results of each test are provided under Tab E. 4.3.1 Field Data QA/QC Evaluation The QAM performs a review of all field recorded data to assess adherence with QAP, Permit, and Sampling Plan requirements. The assessment involved review of the Field Data sheets. Review of the Field Data Sheets noted that all requirements for field data collection were met. 4.3.2 Holding Time Evaluation QAP Table 1 identifies the method holding times for each suite of parameters. Sample holding time checks are provided under Tab E. All samples except as noted below were analyzed within the required holding time. Per the analytical method, SVOC samples have two holding times; a 7 day holding time for extraction of the sample and a 40-day holding time for analysis of the extract. The SVOCs in all samples were extracted 1-day beyond the method specified holding time of 7 days. The extracts were analyzed within the 40-day holding time window. This deviation does not affect the quality or usability of the data because the 7-day holding time is set to prevent the loss of SVOC compounds due to biological degradation. Based on the data, the cell solutions and LDS and slimes drain samples were at a pH of 3.88 or less at the time of collection without additional preservative. The pH of the samples at the time of collection provides protection from biological degradation. The holding time for acetone in Cell 2 slimes drain samples were missed. The analysis of acetone in the Cell 2 slimes required a dilution. The initial analysis was within the holding time however, the diluted analysis for acetone was completed beyond the holding time. The initial 6 analysis cannot be reported because the concentration cannot be accurately quantified because the value is above the upper quantitation limit of the instrument calibration. This deviation does not affect the quality or usability of the data because the 14-day holding time is set to prevent the loss of VOC compounds due to biological degradation and volatilization. Based on the data, the cell solutions and LDS and slimes drain samples were at a pH of 3.88 or less at the time of collection without additional preservative. The pH of the samples at the time of collection provides protection from biological growth. Volatilization is not expected to affect the samples because of the stability of the matrix due to the density (high specific gravity). The holding time for fluoride in the Cell 2 slimes drain sample was missed. The laboratory noted that the original analysis was analyzed within holding time however the data are from a recheck analysis that was completed after the holding time expired. The difficult matrix likely caused this issue. Fluoride analyses are completed using a ion-specific electrode. After a number of samples, the electrode likely needed cleaning or repair, which would have resulted in erroneous data. Upon data review, the laboratory noticed the anomaly and reanalyzed the sample beyond the holding time. This deviation does not affect the quality or usability of the data because the holding time is set to prevent the loss of fluoride due to biological degradation and chemical reaction. Based on the data, the cell solutions and LDS and slimes drain samples were at a pH of 3.88 or less at the time of collection without additional preservative. The pH of the samples at the time of collection provides protection from biological growth and chemical reaction. It is important to note that pH is analyzed by the laboratory and is not measured in the field because the acidic nature of the samples requires a more robust meter than what is available for field use. In most circumstances pH is measured at the time of sample collection and a holding time is not assessed. If pH is not measured at the time of collection, a 15-minute time limit is set. EL flagged the pH results with an "H" flag because the pH was measured beyond the 15- minute limit. This does not affect the usability of the data, as the sample matrices are stable and pH is collected for informational purposes only and there are no compliance criteria for pH measurements. 4.3.3 Laboratory Receipt Temperature Check Chain of Custody sheets were reviewed to confirm compliance with the Permit. Sample receipt temperature checks are provided under Tab E. All samples were received within the required temperature limit except as noted below. EL labs subcontracted the SVOC analyses to Eurofins, Denver. EL shipped the samples to Eurofins and four of the SVOCs were received above the required temperature. The SVOC samples for Cell 4 LDS, Cell 4B, Cell 4B LDS and Cell 65 (duplicate of Cell 1) were received at 7 .6°C. This deviation does not affect the quality or usability of the data because the temperature requirements are set to prevent the loss of SVOCs due to biological degradation. Based on the data, the cell solutions and LDS and slimes drain samples were at a pH of 3 .88 or less at the time of collection. The pH of the samples at the time of collection provides protection from biological degradation and the missed temperature requirements do not adversely affect the data. 7 4.3.4 Analytical Method Check All analytical methods reported by both laboratories were checked against the required methods specified in Table 1 of the QAP. It is important to note that neither the QAP nor the Permit specify a method for laboratory pH or conductivity. The QAM verified that the laboratory pH and conductivity methods used by the laboratory were appropriate and provided accurate data. Table 1 of the QAP does not specify a method for SVOCs because SVOCs are not routinely collected in the Mill groundwater samples. The GWDP requires that tailings and slimes drain samples shall include the SVOCs identified in EPA Method 8270D. The GWDP does not specify that EPA Method 8270D be used for analysis, only that the compounds specified in that method be included in the analytical list. All of the SVOCs in the GWDP-specified list were included in the analytical data however EPA Method 8270C, rather than 8270D, was used to complete the analyses. It is important to note that an additional SVOC was included in the analyte list. The extra analyte is included in the data in Tab C. Analytical method check results are provided in Tab E. 4.3.5 Reporting Limit Evaluation All analytical method reporting limits reported by both laboratories were checked against the reporting limits specified in the Permit. Section I.E.4 of the Permit requires the following Reporting Limits: "all water quality analyses reported shall have a minimum detection limit or reporting limit that is less than or equal to the respective: i. Ground Water Quality Standards ("GWQS") concentrations defined in Table 2 of this Permit, ii. For TDS, Sulfate, and Chloride, the Minimum Detection Limit for those constituents for Cell solution monitoring will be as follows: 1,000 mg/L, 1,000 mg/L, and 1 mg/L, respectively, and iii. Lower limits of quantitation for groundwater for semi-volatile organic compounds listed in Table 2 of EPA Method 8270D, Revision 4, dated February, 2007." Reporting limits are provided in Tab E. There are several constituents that do not have specified reporting limits in either the Permit or EPA Method 8270D. The reporting limits established by the laboratory are reported in the data packages. The reporting limits are comparable to other analytes in the same method based on the same matrix. The reporting limits used by the laboratory are considered acceptable based on the matrix and known difficulties caused by the sample matrix. 8 There are several SVOC compounds that had reporting limits that exceeded the reporting limits listed in Method 8270D in all samples. Those compounds are: • 3,3'Dichlorobenzidine -2019 reporting limit= 50 ug/L • Hexachlorobutadiene -2019 reporting limit = 26 to 30 ug/L • Hexachloroethane -2019 reporting limit = 26 to 30 ug/L The laboratory method detection limit ("MDL") for each of these compounds is below the reporting limits listed above and the MDL is below the specified reporting limit in Method 8270D. If the compounds were detected below the reporting limit but above the MDL, the laboratory would have rep01ted the data and qualified the result with a "J" as they did for other compounds (for example MEK in Cell 1). Because the MDLs are below the Method 8270D specified reporting limits, and because any detections would have been reported, the 2019 data are comparable to historic data and are usable for the intended purpose. Two additional reporting limit exceedances were noted. The reporting limits for thallium in Cell 1 and lead in Cell 3 exceeded the GWQSs. These exceedances were likely the result of dilutions necessary to address the matrix interferences inherent in these samples. The exceedances do not affect the quality or usability of the data because the results of this sampling provide an "inventory" of cell composition and are not used for comparison to regulatory limits. In addition, several sets of sample results had the reporting limit raised for at least one analyte due to sample dilution. In all cases the reported value for the analyte was higher than the increased detection limit. 4.3.6 Trip Blank Evaluation All trip blank results were reviewed to identify any blank contamination. Trip blank evaluations are provided in Tab E. All trip blank results associated with the samples were less than the reporting limit for all voes. 4.3.7 QA/QC Evaluation for Sample Duplicates Section 9.1.4 a) of the QAP states that the relative percent difference (the "RPD") will be calculated for the comparison of duplicate and original field samples. The QAP acceptance limits for RPDs between the duplicate and original field sample is less than or equal to 20% unless the measured results are less than 5 times the required detection limit. This standard is based on the EPA Contract Laboratory Program National Functional Guidelines for Inorganic Data Review, February 1994, 9240.1-05-01 as cited in the QAP. The RPDs are calculated for all duplicate pairs for all analytes regardless of whether or not the reported concentrations are greater than 5 times the required detection limits; however, data will be considered noncompliant only when the results are greater than 5 times the required detection limit and the RPD is greater than 20%. RPDs are also only calculated when both the sample and the duplicate report a detection for any 9 given analyte. If only one of the pair reports a detection the RPD cannot be calculated. The additional duplicate information is provided for information purposes. All duplicate results were within 20% RPD except for magnesium, potassium, sodium, and gross alpha in the duplicate pair Cell 1/Cell 65. The gross alpha duplicate results are discussed in Section 4.3.8 below. The chromium and selenium RPDs were greater than 20%, however the sample and duplicate results reported for Cell 1/Cell 65 were not five times greater than the RLs, and, as such, the deviation from the 20% RPD requirement is acceptable. The magnesium, potassium, and sodium results for the duplicate sample Cell 1/Cell 65 did not meet the duplicate comparability check. Per the approved QAP, and in response to requests from DWMRC, a separate corrective action for duplicate RPDs outside of acceptance limits has been developed. The revised procedure for duplicate results outside of acceptance limits was implemented. The corrective actions that were taken in accordance with the revised procedure are as follows: the QAM contacted the Analytical Laboratory and requested a review of the raw data to assure that there were no transcription errors and the data were accurately reported. The laboratory noted that the data were accurate and reported correctly. Reanalysis was not completed as the RPDs above the limit are likely due to interferences caused by the matrix, as discussed below. There is no effect on the usability of the data due to the duplicate results exceeding the comparability criteria because the matrix of the sample solution caused the noncompliance. Results of the RPD test are provided under Tab E. The radiologic duplicates are discussed in Section 4.3.8 below. 4.3.8 Radiologic Counting Error Section 9.14 of the QAP requires that all gross alpha analysis reported with an activity equal to or greater than the Groundwater Compliance Limit (the "GWCL") (for the tailings system wastewater samples the GWQS will be used), shall have a counting variance that is equal to or less than 20% of the reported activity concentration. An error term may be greater than 20% of the reported activity concentration when the sum of the activity concentration and error term is less than or equal to the GWQS. Results of routine radiologic sample QC are provided under Tab E. All tailings system wastewater radiologic sample results met the counting error requirement. Section 9.1.4 of the QAP also requires a comparability check between the sample and field duplicate sample results utilizing the formula provided below: The original and duplicate sample did not meet the duplicate comparability check specified in the QAP for gross alpha. Results of the RPD test are provided under Tab E. Per the approved QAP, and in response to requests from DWMRC, a separate corrective action for duplicate RPDs 10 outside of acceptance limits has been developed and is documented in the revised QAP. The revised procedure for duplicate results outside of acceptance limits was implemented for the gross alpha results in duplicate pair Cell 1/Cell 65. The corrective actions that were taken in accordance with the revised procedure are as follows: the QA Manager contacted the Analytical Laboratory and requested a review of the raw data to assure that there were no transcription errors and the data were accurate I y reported. The laboratory noted that the data were accurate and reported correctly. Reanalysis was not completed as the RPDs above the limit are likely due to interferences caused by the matrix as discussed below. The lack of comparability of the gross alpha results is indicative of a matrix inte1ference and does not affect the usability of the data. Matrix interference is most likely caused by high concentrations of TDS and other constituents in the sample. 4.3.9 Laboratory Matrix QC Evaluation Section 9.2 of the QAP requires that the laboratory's QA/QC Manager check the following items in developing data reports: (1) sample preparation information is correct and complete, (2) analysis information is correct and complete, (3) appropriate analytical laboratory procedures are followed, (4) analytical results are correct and complete, (5) QC samples are within established control limits, (6) blanks are within QC limits, (7) special sample preparation and analytical requirements have been met, and (8) documentation is complete. In addition to other laboratory checks described above, EFRI's QAM rechecks QC samples and blanks (items (5) and (6)) to confirm that the percent recovery for spikes and the relative percent difference for spike duplicates are within the method-specific required limits, or that the case narrative sufficiently explains any deviation from these limits. Results of this quantitative check are provided under Tab E. All lab QA/QC results from both EL and GEL met these requirements. There were QC results which did not meet laboratory established acceptance limits, as identified in Tab E and described below. A significant number of the tailings system wastewater samples had the RL raised for multiple analytes due to matrix interference and/or sample dilution. RL evaluations are discussed in Section 4.3.5. The check samples included at least the following: a method blank, a laboratory control spike ("LCS"), a matrix spike ("MS") and a matrix spike duplicate ("MSD"), or the equivalent, where applicable. All qualifiers, and the corresponding explanations reported in the QA/QC Summary Reports for any of the check samples for any of the analytical methods were reviewed by the QAM. The QAP Section 8.1.2 requires that a MS/MSD pair be analyzed with each analytical batch, depending upon the analytical method requirements and/or method limitations. The QAP does not specify acceptance limits for the MS/MSD pair, and the QAP does not specify that the MS/MSD pair be prepared on EFRI samples only. Acceptance limits for MS/MSDs are set by the laboratories. The review of the information provided by the laboratories in the data packages 11 verified that the QAP requirement to analyze a MS/MSD pair with each analytical batch was met. While the QAP does not require it, the recoveries were reviewed for compliance with the laboratory established acceptance limits. The QAP does not require this level of review, and the results of this review are provided for information only. The information from the Laboratory QA/QC Summary Reports indicates that the MS/MSDs recoveries and the associated RPDs were within acceptable laboratory limits for all regulated compounds. The QAP specifies that surrogate compounds shall be employed for all organic analyses but the QAP does not specify acceptance limits for surrogate recoveries. The analytical data associated with the routine quarterly sampling met the requirement specified in the QAP. The information from the Laboratory QA/QC Summary Reports indicates that the surrogate recoveries for all tailings system wastewater samples were within acceptable laboratory limits for all surrogate compounds except as indicated in Tab E. There are ten surrogate recoveries outside of acceptance limits for the SVOC analyses. In all instances the surrogate recoveries outside of acceptance limits were the result of a matrix interference. A matrix interference resulted in the surrogate compounds being outside of the acceptance limits noted in Tab E. There are other surrogate compounds used for SVOC analyses which were all within acceptance limits. As such there is no effect on the quality or usability of the data. Since surrogate compounds were added to all of the organic analyses as required by the QAP, the data are compliant with the QAP requirements. The information from the Laboratory QA/QC Summary Reports indicates that the LCS/LCSD recoveries for the samples were within acceptable laboratory limits for all LCS/LCSD compounds except as noted in Tab E. The compounds noted with LCS/LCSD recoveries outside of acceptance limits are noted for low recovery and the surrogate recoveries associated with the LCS/LCSD indicate that the analytical system was operating within acceptable limits and the data are acceptable as reported and there is no effect on the usability of the data. The QAP, Section 8.1.2 requires that each analytical batch shall be accompanied by a method blank. The analytical batches routinely contain a blank, which is a blank sample made and carried through all analytical steps. For the Mill samples, a method blank was prepared for the analytical methods. Per the approved QAP, contamination detected in analysis of method blanks will be used to evaluate any analytical laboratory contamination of environmental samples. The QAP states that non-conformance conditions will exist when contaminant levels in the samples(s) are not an order of magnitude greater than the blank result. There were no detections in the method blanks in this quarter. Method blank results are included in Tab E. 5.0 HISTORIC DATA The historic analytical data for the tailings system wastewater sampling program are included in Tab D. In addition, the minimum and maximum concentrations compiled in the DWMRC 12 GWDP, Statement of Basis for a Uranium Mining Facility at White Mesa, South of Blanding, Utah, dated December 1, 2004 are included in Tab D. 6.0 SUMMARY AND CONCLUSIONS 6.1 Cell 1 Cell 1 solutions were acidic in nature with a laboratory pH of 1.14. As expected, the solutions contained gross alpha, major ions, metals, and Volatile Organic Compounds ("VOCs"). SVOCs were not detected. Regarding major ions, chloride, fluoride, magnesium, ammonia, potassium, sodium and sulfate were one or more orders of magnitude greater in concentration than the other major ions. Metals exhibiting the greatest concentration by at least one order of magnitude higher than the other metals analyzed included arsenic, cadmium, chromium, cobalt, copper, iron, lead, manganese, molybdenum, nickel, selenium, uranium, vanadium and zinc. A decrease was noted in the gross alpha concentration in the August 2019 sample, but it is the same order of magnitude as the 2018 sample. The variable gross alpha results are being caused by matrix interference due to the nature of the tailings solution and are not representative of gross alpha from radium concentrations in the solution. This is evidenced by the results of the voluntary additional analyses. The results of the voluntary analyses are shown in Tab D. The concentrations reported in the 2019 sample remained within historic ranges. It is important to note that not all constituents present in the tailings fluids will exhibit the same behavior as a result of concentration of the tailings fluids and any increases or decreases in constituent results will not be linear. The individual constituent results are greatly affected by the matrix of the tailings fluids and each constituent will behave differently based on the matrix interactions and the differing solubility properties of the constituent. Comparison of Cell 1 fluids to those of Cells 4A, and 4B reveals that Cell 1 1s similar in composition and concentration ratios to the fluids in Cells 4A and 4B. 6.2 Cell 3 Cell 3 solutions were acidic in nature, with a laboratory pH of 3.88. As expected, the solutions contained gross alpha, major ions, metals, and VOCs. SVOCs were not detected. Regarding major ions, chloride, fluoride, magnesium, ammonia, sodium and sulfate were generally one or more orders of magnitude greater in concentration than the other major ions. Metals exhibiting the greatest concentration by at least one order of magnitude greater than the other metals analyzed included cadmium, cobalt, copper, iron, manganese, nickel, selenium, uranium, vanadium and zinc. A decrease in the gross alpha and many metals and ions concentrations was noted in the August 2019 sample. The reason for the increase in many constituent concentrations was due to the increased precipitation in early 2019, which would have flowed into Cell 3. As a result of the additional precipitation, the liquid was diluted. Gross alpha results are not representative of gross alpha from radium concentrations in the solution. This is evidenced by the results of the voluntary additional analyses which are shown in Tab D. 13 The concentrations reported in the 2019 sample are similar to previous results. It is important to note that not all constituents present in the tailings fluids will exhibit the same behavior as a result of concentration of the tailings fluids and the increases in constituent results will not be linear. The individual constituent results are greatly affected by the matrix of the tailings fluids and each constituent will behave differently based on the matrix interactions and the differing solubility properties of the constituent. 6.3 Cell 4A Cell 4A solutions were acidic in nature, with a laboratory pH of 2.40. As expected, the solutions contained gross alpha, major ions, metals, and VOCs. One SVOC was detected. Cell 4A fluid exhibited the highest major ion concentrations for chloride, fluoride, magnesium, ammonia, potassium, sodium and sulfate. The metals arsenic, cadmium, chromium, cobalt, copper, iron, lead, manganese, molybdenum, nickel, selenium, uranium, vanadium and zinc were one or more orders of magnitude greater than the other metals analyzed. A decrease in the gross alpha concentration was noted in the 2019 sample. The variable and decreased gross alpha results are being caused by matrix interference due to the nature of the tailings solution and are not representative of gross alpha from radium concentrations in the solution. This is evidenced by the results of the voluntary additional analyses which are shown in Tab D. Overall, the concentrations reported in the 2019 sample remained approximately the same as the 2018 sample. Concentration changes noted are within the analytical accuracy of the methods used for analysis. It is important to note that not all constituents present in the tailings fluids will exhibit the same behavior as a result of concentration of the tailings fluids and the increases in constituent results will not be linear. The individual constituent results are greatly affected by the matrix of the tailings fluids and each constituent will behave differently based on the matrix interactions and the differing solubility properties of the constituent. Comparison of Cell 4A fluids to those of Cells 1, and 4B reveals that Cell 4A is similar in composition and concentration ratios to the fluids in Cells 1, and 4B. 6.4 Cell 4B Cell 4B solutions were acidic in nature, with a laboratory pH of 1.53. As expected, the solutions contained gross alpha, major ions, metals and VOCs. One SVOCs was detected. Cell 4B fluid exhibited the highest major ion concentrations for chloride, fluoride, magnesium, potassium, sodium and sulfate. The metals arsenic, cadmium, chromium, cobalt, copper, iron, lead, manganese, molybdenum, nickel, selenium, uranium, vanadium and zinc were one or more orders of magnitude greater than the other metals analyzed. A decrease in the gross alpha concentration was noted in the 2019 sample, but it is the same order of magnitude as the 2018 sample. The variable gross alpha results are being caused by matrix interference due to the nature of the tailings solution and are not representative of gross alpha from radium concentrations in the solution. This is evidenced by the results of the voluntary additional analyses which are shown in Tab D. 14 The concentrations reported in the 2019 sample remained approximately the same as the 2018 sample. Concentration changes noted are within the analytical accuracy of the methods used for analysis. It is important to note that not all constituents present in the tailings fluids will exhibit the same behavior as a result of concentration of the tailings fluids and the increases in constituent results will not be linear. The individual constituent results are greatly affected by the matrix of the tailings fluids and each constituent will behave differently based on the matrix interactions and the differing solubility properties of the constituent. Comparison of Cell 4B fluids to those of Cells 1, and 4A reveals that Cell 4B is similar in composition and concentration ratios to the fluids in Cells 1, and 4A. 6.5 Cell 2 Slimes Drain Cell 2 Slimes drain fluid was acidic in nature, with a laboratory pH of 3.07. As expected, the solutions contained gross alpha, major ions, metals, and VOCs. Five SVOCs were detected. Major ions that were highest in concentration by one or more orders of magnitude included chloride, magnesium, ammonia, sodium and sulfate. For metals, arsenic, cadmium, chromium, cobalt, copper, iron, manganese, molybdenum, nickel, selenium, uranium, vanadium and zinc were at least one order of magnitude greater in concentration than other metals analyzed. A slight decrease in the gross alpha concentration was noted in the 2019 sample. The gross alpha result decreased but is the same order of magnitude of the historic data. Overall, the concentrations reported in the 2019 sample remained approximately the same as the 2018 sample. Concentration changes noted are within the analytical accuracy of the methods used for analysis. 6.6 Cells 3, 4A and 4B Slimes Drain In accordance with the Permit, the slimes drains for Cell 3, 4A and 4B are not required to be sampled until dewatering operations have begun. Cell 1 was designed to be used solely as an evaporation pond and does not have a slimes drain. 6. 7 Cell 2 Leak Detection System Consistent with the Permit, the Cell 2 LDS was not sampled during the 2019 sampling event. The Cell 2 LDS is now dry and covered to prevent precipitation inflow. 6.8 Cells 1 and 3 Leak Detection System Consistent with the Permit, the Cells 1 and 3 leak detection systems were not sampled during the 2019 sampling event because the systems were dry. 6.9 Cell 4A Leak Detection System Cell 4A LDS solutions were acidic in nature, with a laboratory pH of 2.39. As expected, the solutions contained gross alpha, major ions, metals and VOCs. One SVOC was detected. Cell 4A LDS fluid exhibited the highest major ion concentrations for chloride, fluoride, magnesium, 15 ammonia, potassium, sodium, and sulfate. The metals arsenic, cadmium, chromium, cobalt, copper, iron, manganese, molybdenum, nickel, selenium, uranium, vanadium, and zinc were one or more orders of magnitude greater than the other metals analyzed. An increase in the gross alpha concentration was noted in the 2019 sample. The variable gross alpha results are being caused by matrix interference due to the nature of the tailings solution and are not representative of gross alpha from radium concentrations in the solution. This is evidenced by the results of the voluntary additional analyses which are shown in Tab D. Overall, the concentrations reported in the 2019 Cell 4A LDS sample remained within historic ranges. 6.10 Cell 4B Leak Detection System Cell 4B LDS solutions were acidic in nature, with a laboratory pH of 1.53. As expected, the solutions contained gross alpha, major ions, metals, VOCs and one SVOC. Cell 4B LDS fluid exhibited the highest major ion concentrations for chloride, fluoride, magnesium, ammonia, potassium, sodium, and sulfate. The metals arsenic, cadmium, chromium, cobalt, copper, iron, lead, manganese, molybdenum, nickel, selenium, uranium, vanadium and zinc were one or more orders of magnitude greater than the other metals analyzed. A slight decrease in the gross alpha concentration was noted in the 2019 sample, but it is the same order of magnitude as the 2018 sample. The variable gross alpha results are being caused by matrix interference due to the nature of the tailings solution and are not representative of gross alpha from radium concentrations in the solution. This is evidenced by the results of the voluntary additional analyses which are shown in Tab D. Overall, the concentrations reported in the 2019 Cell 4B LDS sample are within historic ranges. 6.11 Summary and Conclusions of Analytical Results The metals arsenic, cadmium, chromium, cobalt, copper, iron, manganese, molybdenum, nickel, selenium, uranium, vanadium and zinc were generally present in greatest concentration for all samples. For major ions, chloride, fluoride, magnesium, ammonia, sodium, and sulfate were predominant. Both increases and decreases were noted for several metals and major anions. Concentrations are variable and are driven by Mill operations. EFRI conducted additional voluntary analyses (not required by the GWDP) in order to further characterize the radiological and physical properties of the tailings solution, as discussed Section 3 .1 above. The results of the additional voluntary analyses for radium-226, thorium-228, thorium-230, thorium-232, uranium- 233/234, uranium-235/236, uranium-238, and specific gravity show that the variability in gross alpha results are being caused by matrix interference due to the nature of the tailings solution and are not representative of gross alpha from radium concentrations in the solution. EFRI may or may not choose to continue these additional analyses in the future. The changes in concentrations of metals and major ions are reflective of Mill operations and are driven by the addition/movement of fluids during periods of operation. The individual constituent results are greatly affected by the matrix of the tailings fluids and each constituent will behave differently based on the matrix interactions and the differing solubility properties of the constituent. Overall, 16 the results of the 2019 tailings solutions are within historic, expected ranges. 7.0 CORRECTIVE ACTION REPORT No corrective action reports are required for the 2019 annual sampling event. 7.1 Assessment of Corrective Actions from Previous Period No corrective action reports were required for the 2018 annual sampling event and as such there is no assessment of previous actions necessary. 17 8.0 SIGNATURE AND CERTIFICATION This document was prepared by Energy Fuels Resources (USA) Inc.

Samples that are hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun. GROSS ALPHA ANALYSIS Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by this method for non potable waters should be viewed as inconsistent. RADON IN AIR ANALYSIS The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to beginning of counting should not exceed 8 days. SOIUSOLID SAMPLES All samples reported on an as received basis unless otherwise indicated. ATRAZINE, SIMAZINE AND PCB ANALYSIS Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven individual Aroclors. When the results for all seven are ND (not detected), the sample meets EPA compliance criteria for PCB monitoring.

SEMIVOLATILE ORGANIC COMPOUNDS (GC-MS) Samples C19081073-001D (280-127755-2), C19081073-002D (280-127755-5), C19081073-003D (280-127755-8), C19081073-004D (280-127755-11), C19081073-005D (280-127755-14), C19081073-0060 (280-127755-17), C19081073-007D (280-127755-20) and C19081073-008D (280-127755-23) were analyzed for semivolatile organic compounds (GC-MS) in accordance with EPA SW-846 Method 8270C. The samples were prepared on 08/29/2019 and analyzed on 09/12/2019 and 09/17/2019. The following samples were diluted due to the nature of the sample matrix: C 19081073-0040 (280-127755-11) and C 19081073-006D (280-127755-17). Elevated reporting limits (Rls) are provided. The following samples formed emulsions during the extraction procedure: C19081073-001D (280-127755-2), C19081073-002D Page 4 of 54 Eurofins TestAmerica, Denver Page 50 <9~2019 I Client: Energy Laboratories, Inc. Project/Site: 11 (e) Byproduct Material J.!)b ID:_280-127755-1 (Continued) Case Narrative Laboratory: Eurofins TestAmerica, Denver (Continued) Job ID: 280-127755-1 (280-127755-5), C 19081073-003D (280-127755-8), C 19081073-004D (280-127755-11 ), C 19081073-005D (280-127755-14 ), C19081073-006D (280-127755-17), C19081073-007D (280-127755-20) and C19081073-008D (280-127755-23). The emulsions were broken up using a pour back technique. The laboratory was unable to preform the base extraction due to emulsion that did not allow the sample to separate sufficiently: C19081073-001D (280-127755-2), C19081073-002D (280-127755-5), C19081073-003D (280-127755-8), C19081073-004D (280-127755-11), C19081073-005D (280-127755-14), C19081073-006D (280-127755-17), C19081073-007D (280-127755-20) and C19081073-008D (280-127755-23). Due to the high density of the sample matrix (>1 .0 g/ml), the initial volumes used for the following samples deviated from the standard procedure: C19081073-001D (280-127755-2), C19081073-004D (280-127755-11) and C19081073-008D (280-127755-23). The reporting limits (Rls) have been adjusted proportionately. The following samples were prepared outside of preparation holding time due to the samples being received on the last day of the method holding time. As such, the laboratory had insufficient time to extract the samples in hold: C19081073-001 D (280-127755-2), C 19081073-002D (280-127755-5), C 19081073-003D (280-127755-8), C 19081073-004D (280-127755-11), C 19081073-005D (280-127755-14), C19081073-006D (280-127755-17), C19081073-007D (280-127755-20) and C19081073-008D (280-127755-23). Due to matrix interference, the following samples failed the surrogate recovery criteria low: C19081073-004D (280-127755-11), (280-127755-17), C 19081073-0010 (280-127755-2), C 19081073-008D (280-127755-23). The laboratory control sample duplicate (LCSD) for preparation batch 280-469200 and analytical batch 280-470328 recovered outside control limits for the following analytes: 1,2,4,5-Tetrachlorobenzene and 1, 1'-Biphenyl. 1,2,4,5-Tetrachlorobenzene and 1, 1 '-Biphenyl have been identified as a poor performing analytes when analyzed using this method; therefore, re-extraction/re-analysis was not performed. 1,2,4-Trichlorobenzene, 1,2-Dichlorobenzene, 1,3-Dichlorobenzene, 1,4-Dichlorobenzene, Hexachlorobutadiene and lndene failed the recovery criteria low for LCS 280-469200/2-A. Several analytes failed the recovery criteria low for LCSD 280-469200/3-A. Pyridine exceeded the LCS/LCSD RPD limit. Refer to the QC report for details. Due to expired holding times data was reported as is and flagged appropriately. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Project: 11 (e) Byproduct Material Report Number: 280-127755-2 Job ID: 280-127755-2 With the exceptions noted as flags or footnotes, standard analytical protocols were followed in the analysis of the samples and no problems were encountered or anomalies observed. In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. Calculations are performed before rounding to avoid round-off errors in calculated results. All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below. RECEIPT The samples were received on 8/28/2019 10:45 AM; the samples arrived in good condition, properly preserved and, where required, on ice. The temperatures of the 3 coolers at receipt time were 2.5° C, 2.8° C and 7.6° C. Receipt Exceptions The following sample was received by the laboratory; however, it was not listed on the Chain-of-Custody (COG): M3-54865 (280-127755-25). The sample was logged per the information stated on the sample container. The following samples were received at the laboratory outside the required temperature criteria: C19081073-005D (280-127755-14), C19081073-006D (280-127755-17), C19081073-007D (280-127755-20), and C19081073-008D (280-127755-23).

The samples were prepared on 10/24/2019 and analyzed on 10/26/2019 and 10/29/2019. Preparation Batch 160-447588, Analytical Batch 160-447983: The serial dilution was outside control limits for Calcium indicating a potential matrix interference. : (240-119832-R-1-C SD) The MS/MSD/serial dilution was analyzed on a different job within the preparation batch. The sample chosen for batch QC had a different analyte list and QC requirements. As a result, the MS/MSD/serial dilution for Arsenic, Cobalt, Copper, Iron, Manganese, Molybdenum, Nickel, Selenium, and Zinc was not applied to this job. Method performance is demonstrated by acceptable LCS recovery: (240-119832-R-1-D MS), (240-119832-R-1-E MSD), and (240-119832-R-1-C SD).

Project: 11 (e) Byproduct Material Report Number: 280-127755-2 -Revision 1 Job ID: 280-127755-2 With the exceptions noted as flags or footnotes, standard analytical protocols were followed in the analysis of the samples and no problems were encountered or anomalies observed. In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. Calculations are performed before rounding to avoid round-off errors in calculated results. All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below. This revision adds results for Sn. RECEIPT The samples were received on 8/28/2019 10:45 AM ; the samples arrived in good condition, properly preserved and, where required, on ice. The temperatures of the 3 coolers at receipt time were 2.5° C, 2.8° C and 7.6° C. Receipt Exceptions The following sample was received by the laboratory; however, it was not listed on the Chain-of-Custody (COC): M3-54865 (280-127755-25). The sample was logged per the information stated on the sample container. The following samples were received at the laboratory outside the required temperature criteria: C19081073-005D (280-127755-14), C19081073-006D (280-127755-17), C19081073-007D (280-127755-20), and C19081073-008D (280-127755-23). DISSOLVED METALS (ltP/MS) Samples C19081073-001C (280-127755-1), C19081073-002C (280-127755-4), C19081073-003C (280-127755-7), C19081073-004C (280-127755-10), C19081073-005C (280-127755-13), C19081073-006C (280-127755-16), C19081073-007C (280-127755-19), C19081073-008C (280-127755-22) and M3-54865 (280-127755-25) were analyzed for Dissolved Metals (ICP/MS) in accordance with 200.8. The samples were prepared on 10/24/2019 and analyzed on 10/26/2019 and 10/29/2019. Preparation Batch 160-447588, Analytical Batch 160-447983: The serial dilution was outside control limits for Calcium indicating a potential matrix interference. : (240-119832-R-1-C SD) The MS/MSD/serial dilution was analyzed on a different job within the preparation batch. The sample chosen for batch QC had a different analyte list and QC requirements. As a result, the MS/MSD/serial dilution for Arsenic, Cobalt, Copper, Iron, Manganese, Molybdenum, Nickel, Selenium, and Zinc was not applied to this job. Method performance is demonstrated by acceptable LCS recovery: (240-119832-R-1-D MS), (240-119832-R-1-E MSD), and (240-119832-R-1-C SD). The following samples were diluted to bring the concentration of target analytes within the calibration range.
