2022 ANNUAL TAILINGS SYSTEM WASTEWATER SAMPLING REPORT
1.0 INTRODUCTION
This is the 2022 Annual Tailings System Wastewater Sampling Report for 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.
The 2022 sampling event was conducted August 24, 2022.
2.0 SUMMARY OF MILL TAILINGS SYSTEM ACTIVITIES IN 2022
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 rep01ting 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 and1 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 Millwastes and 1 le.(2) material from in-situ recovery ("ISR") operations;•Cell 4A: receives Mill tailings and is used for evaporation of Mill solutions; and•Cell 4B: is used for evaporation of Mill solutions.

sample aliquots at Cell 1.
Maps showing the locations of the solution and slimes drain and, when applicable, LDS 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 24, 2022 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 24, 2022 sampling event are included in
separate data tables in Tab D. The gross alpha results have been evaluated and are included as
required. These additional data are included in this report for informational purposes only. EFRImay 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 DWMRC-approved Sampling Plan, Revision 3.0, dated July 8, 2016, field filtering and preservation of metals and gross alpha ample aliquots was not completed due to safety concerns associated with the filtering apparatu 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 LDS and slimes drain . amples are at a low pH 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.
3.3.1 Cells
Cell solution samples were collected as noted above, at the cell sampling stations shown on the
Figures in Tab B, using approved procedures described in the DWMRC-approved Sampling Plan, Section 3.1.2.
Disposable or dedicated sampling equipment was used during this sampling event and, as such, rinsate samples were not required.

in the analytical list. All of the SVOCs in the GWDP-specified list were included in the analytical data The analytical data are included 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 constituentsfor 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 compoundslisted 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.
The VOCs and all of the SVOCs had reporting limits that exceeded the reporting limits listed in
the permit or the method respectively.
The VOCs that had reporting limits that exceeded the reporting limits are:
•Methylene chloride in Cell 1, Cell 2 Slimes, Cell 4A, Cell 4A LDS, Cell 4B, Cell 4B LDS-2022 reporting limit = 25 ug/L
All samples had methylene chloride RLs above the permit required RL of 5 ug/L. 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.
The reporting limits for the SVOCs exceeded the recommended RLs in Method 8270D. GEL
provided both a method detection limit ("DL") and RL. The DL is based on the sample 7
composition and other sample-specific variables such as TDS and pH. EPA Method 8270D
provides "recommended" quantitation limits for water samples. The tailings solution matrix is not comparable to routine groundwater samples and require dilutions to address these matrix interferences. The laboratory will report detections to the DL and therefore that is the lowest limit for reporting (i.e. the RL). These RL 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
rep01ting limit for the VOCs.
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 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 acetone and methyl ethyl ketone ("MEK or
2-butanone) in the duplicate pair Cell 4A LDS/Cell 65. The MEK results were greater than 20%
RPD, however, the sample and duplicate results were not greater than 5 times the RL and as such
are acceptable. Per the approved QAP, and in response to requests from DWMRC, a separatecorrective action for duplicate RPDs outside of acceptance limits has been developed. The revisedprocedure for duplicate results outside of acceptance limits was implemented. The correctiveactions that were taken in accordance with the revised procedure are as follows: the Director,Regulatory Compliance contacted the Analytical Laboratory and requested a review of the rawdata 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

6. 7 Cells 1, 2, and 3 Leak Detection Systems
Consistent with the Permit, the Cells 1, 2, and 3 LDSs were not sampled during the 2022 sampling
event. The Cells 1, 2, and 3 LOSs were dry.
6.8 Cell 4A Leak Detection System
Cell 4A LOS solutions were acidic in nature, with a laboratory pH of 2.5. As expected, the solutions contained gross alpha, major ions, metals and VOCs. No SVOCs were detected. Cell
4A LOS fluid exhibited the highest major ion concentrations for chloride, fluoride, magnesium,
ammonia, sodium, and sulfate. The metals arsenic, cadmium, chromium, cobalt, copper, iron, lead, manganese molybdenum, nickel, selenium, uranium, vanadium, and zinc were one or more ord r of magnitude greater than the other metals analyzed. A slight increa e in the gro s alpha concentration compared to the 2021 ample wa noted. The variable gro alpha re ult are being caused by matrix interference due to the nature of the tailing elution and are not repre entative
of gro . alpha from radium concentrations in lhe . elution. Thj is evidenced by the result of the voluntary additional analy e wbicb are shown in Tab 0.
The concentrations reported in the 2022 sample remained within historic ranges. Iron repo1ted concentrations were below the historic ranges. The concentrations which fall outside of the
historic ranges are due to analytical error, and matrix interferences during the analyses caused by
the inherent composition of the fluids.
6.9 Cell 4B Leak Detection System
Cell 4B LOS solutions were acidic in nature, with a laboratory pH of 2.2. As expected, the
solutions contained gross alpha, major ions, and metals. Four VOCs were detected. One SVOC
was detected. Cell 4B LOS fluid exhibited the highest major ion concentrations for chloride, fluoride, magnesium, ammonia, odium, and sulfate. The metals arsenic, cadmjum, 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 gro s alpha concentration wa noted in the 2022 sample. The variable gro alpha results are being
caused by matrix interference due to the nature of the tailings solution and are not repre entative of gro alpha from radium concentration. in the olution. Thi is evidenced by the results of the voluntary additional analy e which are bown in Tab 0.
The majority of the concentration reported in the 2022 sample were below bi toric range . Magne ium, potas ium� sulfate IDS arsenic beryllillm cadmium, chromium, copper iron lead, molybdenum, selenium silver thaUium, and uranium had reported concentration below the
historic range . The c ncentration which fall outside of the historic ranges are due to changes in
the Cell 4B solutions caused by effects from the severe local drought, routine sampling and analytical error, and matrix interferences during the analyses caused by the inherent composition of the fluids.

ORIGINAL SAMPLE SUBMITTAL(S) All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4°C (±2°C)
Report Date: 09/19/22
CASE NARRATIVE
Temperature of samples received may not be considered properly preserved by accepted standards. 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.
SUBCONTRACTING ANALYSIS Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the Laboratory Analytical Report.

________ ........................... _____________________________ , ____________________________________________________________________________________________________________ , -----------------------------------------------------------------------------------------------------------------------------------------------------1 Standard Reporting Procedures:
Lab measurement of analytes considered field parameters that require analysis within 15 minutes of sampling such as pH, Dissolved Oxygen and Residual Chlorine, are qualified as being analyzed outside of recommended holding time.
Solid/soil samples are reported on a wet weight basis (as received) unless specifically indicated. If moisture corrected, data units are typically noted as -dry. For agricultural and mining soil parameters/characteristics, all samples are dried and ground prior to sample analysis.
The reference date for Radon analysis is the sample collection date. The reference date for all other Radiochemical analyses is the analysis date. Radiochemical precision results represent a 2-sigma Total Measurement Uncertainty.
Contact and Corrective Action Comments:
Dissolved Metals/Hardness were filtered and preserved to pH <2 with 2 ml of nitric acid per 250 ml in the laboratory. According to 40CFR136, samples for Dissolved Metals should be filtered and preserved within 15 minutes of collection.

Spike Recovery Statement
The MSO (See Below) did not meet spike recovery acceptance criteria. The associated MS and LCS met spike
recovery acceptance criteria. It appears that the low recoveries were isolated to the MSO only and may have
been the result of a poor extraction. There is insufficient sample remaining to perform a re-extraction. The data
results were reported.
Sample Analyte

MS/MSD Relative Percent Difference (RPO) Statement
The RPO values between the MS and MSO, (See Below), were not within the acceptance limits due to the large
difference between the individual recoveries in each MS and MSO analyte pair. There is insufficient sample
remaining to perform a re-extraction. The data results were repmted.

591138007 (Cell 65) in this SOG in this batch.
Additional Comments
Diphenylamine Statement Oiphenylamine has now superseded N-Nitroso-diphenylamine as a CCC in EPA Method 8270C. Previous versions of EPA Method 8270 (prior to 8270C) listed N-Nitroso-diphenylamine as a CCC. However, as stated in EPA Method 8270C, Revision 3, December, 1996, Section 1.4.5, "N-Nitroso-diphenylamine decomposes in the gas chromatographic inlet and cannot be separated from Oiphenylamine." Studies of these two compounds at GEL, both independent of each other and together, show that they not only coelute, but also have similar mass spectra. The GEL Mobile Lab will report N-Nitroso-diphenylamine and Diphenylamine as
N-Nitroso-diphenylamine on all reports and forms.
