Re: Transmittal ofQl-24 Data Quality Report ("DQR") for the White Mesa Cell 2 Cover Test
Section Monitoring
Dear Mr. Hansen :
In accordance with the Stipulation and Consent Agreement ("SCA") dated February 23, 2017, between the
Division of Waste Management and Radiation Control ("DWMRC") and Energy Fuels Resource (USA) Inc.
("EFRI"), EFRI constructed a cover performance monitoring test section on Cell 2 in 2016 and initiated
performance monitoring. This letter transmits the data quality report for monitoring data collected during the
first quarter of 2024. Please note that this report is for quality assurance only and does not provide interpretive
information. Interpretive information is provided in annual reports.
For your convenience, two hard copies of the report and two copies on electronic media, each containing a word
searchable electronic copy of the files, will be mailed to DWMRC.
If you should have any questions regarding this transmittal please contact me at 303-389-4134.
Yours very truly,

Q1-24 DATA QUALITY REPORT FOR THE
PRIMARY TEST SECTION
WHITE MESA MILL-TAILINGS MANAGEMENT
CELL2
ENERGY FUELS RESOURCES (USA) INC.
SAN JUAN COUNTY, UTAH
7 April 2024
1.0 INTRODUCTION
This Data Quality Report (DQR) was prepared to document data quality assurance for the
White Mesa Mill cover performance monitoring test section (Primary Test Section) for first
quarter 2024 (Q1-24 ). This report is documentary and not interpretative. The annual report
includes interpretation of the monitoring data.
The Primary Test Section was constructed in August -September 2016 over tailings
management Cell 2 at Energy Fuels Resources (USA) lnc.'s White Mesa Mill in San Juan
County, Utah. Hydrological monitoring was initiated on 29 September 2016. A large-scale
"ACAP" drainage lysimeter monitors the test section. The lysimeter is equipped to monitor
water balance components and meteorological data.
Fig. 1 shows a profile of the final cover being evaluated at White Mesa (minimum
thickness). Fig. 2 shows a cross-sectional schematic of the lysimeter. The test section is
instrumented with two nests of vertically stacked and co-located sensors to monitor soil
temperature and soil water content, as illustrated in Figs. 1 and 2. The nests are on the
centerline of the test section at the upper and lower third points. Probes in the lower nest
are odd numbered and probes in the upper nest are even numbered. The water content
probes were calibrated with on-site soils collected during construction. Temperature
compensation was incorporated into the calibrations.
Flows from runoff, lateral flow (interflow), and percolation collection points in the test
section are routed via pipe (Fig. 2) to collection basins in a subsurface vault downslope
from the test section. Flow into each basin is monitored by tipping buckets and a pressure
transducer. Flows reported by the tipping bucket are described in terms of "tips," whereas
water elevations reported by the transducers are reported as "stage.'' Flows are reported
in mm of water per unit area. The tipping buckets and pressure transducers were initially
calibrated in September 2016 and have been re-calibrated annually. The most recent
calibration was on 2 August 2023.
2.0 WATER BALANCE DATA
Data within this DQR were collected during Q1-24 from 03 January 2024 to 24 March 24.
These dates align with automated data downloads and do not correspond precisely to the
conventional start and end of Q1-24. Data for 25 March 2024 and onward will be included
in the Q2-24 report.
Table 1 summarizes the water balance quantities and Fig. 3 shows the water balance
graph for the test section. Fig. 4 shows cumulative percolation along with daily
precipitation measured at the test section. Figs. 5 to 33 show data from each sensor
collected during Q1-24. The quality assurance summary is on pp. 7-8.
Approximately 75 mm of precipitation was recorded in Q1-24, most of which was from a
series of storm events in late January and early February as well as one large event in
mid-March (Fig. 8). The uppermost water content sensors responded to infiltration from
the January and March events, with water contents increasing in the upper 0.5 m of the
cover (Fig. 14). None of the deeper sensors responded to the precipitation events (Figs.
15-20), indicating no deeper penetration of water in Q1-24. Water contents at all other
depths remained essentially constant. A trace of runoff was recorded in response to the
1
aforementioned storms (Fig. 25). A trace of percolation was also transmitted (Fig. 31 ). No
lateral flow was recorded (Fig. 28).
3.0 CONCERNS
Reed switch 1 B on the runoff tipping bucket ceased recording tips in early March. This
reed switch will be replaced during the summer maintenance and calibration exercise. No
data have been lost, as the tipping bucket has two redundant reed switches to count tips
as well as a pressure transducer to record stage.
4.0 RESOLVED ISSUES
No issues needed resolution during Q1-24.
5.0 ACTION ITEMS
Replace reed switch 1 B on the runoff tipping bucket during the annual maintenance and
calibration event in Summer 2024.

DATA QUALITY REPORT SUMMARY: Q1-24
White Mesa Primary Test Section
01/03/24 through 03/24/24
Water Balance Summary
• Table 1 summarizes the water balance of the test section since inception.
• Fig. 3 presents the water balance graph for the test section since inception.
• Fig. 4 shows graphs of daily precipitation and cumulative percolation for the test section
since inception.
Meteorology
• The battery and solar panel are working properly (Fig. 5).
• All meteorological sensors are working properly (Figs. 6-13).
• The on-site precipitation data are generally consistent with, but are smaller than, the
NWS data recorded at the Blanding station (KBDG, 37.62° N, 109.47° W, Elev.: 6001
ft) (Fig.8). Independent precipitation measurements recorded by the Geonor gage
and the tipping bucket are generally in agreement (Fig. 9).
• Solar radiation data are consistent with data recorded at the NWS Blanding station
(Fig. 13).
Test Section
• The WCR probes for measuring water content are functioning properly (Figs. 14-20).
Differences in water content of approximately 0.09 are reported by Probes 3 and 4 in
the growth medium layer at 914 mm bgs (Fig. 16). Differences in water content of
approximately 0.08 are reported by Probes 3 and 4 in the compacted layer at 2134
mm bgs (Fig. 19). Differences in water content of approximately 0.07 are reported by
Probes 1 and 2 in the interim layer at 2743 mm bgs (Fig. 20). These differences in
water content are real and reflect spatial variations in water content that remain from
the deep penetration of a wetting front in Q1-17.
• The thermocouples used to measure soil temperature are functioning properly (Fig. 21 ).
• Flows reported by the transducer and tippers for runoff are reasonably consistent
(Figs. 22-25). However, 3 tips of runoff were recorded from tipper 1A on 3/15/24,
whereas no runoff was recorded from tipper 1 B (Fig.23).
7
• Flows reported by the transducer and tippers for lateral flow are reasonably consistent
(Figs. 24-28).
• Flows reported by the transducer and tippers for percolation are reasonably
consistent (Figs. 29-31 ).
• The vault stage has been negative and decreasing (Fig. 32).
• The voltage sensor that monitors the power supply in the vault is functioning properly
(Fig. 33).
