Q3-23 DATA QUALITY REPORT FOR THE
PRIMARY TEST SECTION
WHITE MESA MILL – TAILINGS MANAGEMENT
CELL 2
ENERGY FUELS RESOURCES (USA) INC.
SAN JUAN COUNTY, UTAH
30 October 2023
1
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 third
quarter 2023 (Q3-23). 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) Inc.’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 Q3-23 from 24 June 2023 to 27 September
2023. These dates align with automated data downloads and do not correspond precisely
to the conventional start and end of Q3-23. Data for 28 September 2023 and onward will
be included in the Q4-23 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 Q3-23. The quality assurance summary is on pp. 7-8.
Approximately 35 mm of precipitation was recorded in Q3-23, most of which is from a set
of storm events in late July and late August (Fig. 8). The uppermost water content sensors
exhibited a slight response to the July precipitation events (Fig. 14). None of the deeper
sensors responded to the precipitation events in July or August, suggesting that infiltration
from these storm events penetrated to shallow depths, and then rapidly transpired (Figs.
15-20). No runoff or lateral flow was transmitted in Q3-23 (Figs. 22-27). Approximately 0.4
mm of percolation was transmitted by thermal gradients. Percolation initiated in early July,
and began tailing approximately one month later (Fig. 29).

3.0 CONCERNS
None at this time.
4.0 RESOLVED ISSUES
The apparent periodic loss of power to the vault that was reported in the previous year
has been resolved. The sensing device used to monitor power in the vault was defective
and replaced during the 2023 annual calibration and maintenance event on 02 August
2023. No apparent or actual power loss has been detected since the repair was made.
5.0 ACTION ITEMS
None at this time.

DATA QUALITY REPORT SUMMARY: Q3-23
White Mesa Primary Test Section
06/24/23 through 09/27/23
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 Geonor gage was
refreshed during a site visit on 02 August 2023 (Figure 7).
• The on-site precipitation data are generally consistent with the NWS data recorded
at the Blanding station (KBDG, 37.62° N, 109.47° W, Elev.: 6001 ft) (Fig. 8), except
on 15 September 2023 when on-site precipitation was 0.7 mm, and the NWS
precipitation was 17.8 mm. Independent precipitation measurements recorded by the
Geonor gage and the tipping bucket are 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 0.07 are reported by Probes 3 and 4 in
the growth medium layer at 914 mm bgs (Fig. 16). Differences in water content of
approximately 0.09 are reported by Probes 9 and 10 in the compacted layer at 2134
mm bgs (Fig. 19). Differences in water content of approximately 0.06 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. 22-24).
8
• Flows reported by the transducer and tippers for lateral flow are reasonably consistent
(Figs. 25-27). The reed switches on the 1-L lateral flow tipper were replaced during
the annual calibration and maintenance on 2 August 2023. Lateral flow reported by
tipper 1A and tipper 1B has been consistent since the reed switches were replaced
(Fig. 25).
• Flows reported by the transducer and tippers for percolation are reasonably
consistent (Figs. 28-31). The reed switches on the 70-mL percolation tipper were
replaced during the annual calibration and maintenance on 2 August 2023.
Percolation reported by tipper 1A and tipper 1B has been consistent since the reed
switches were replaced (Fig. 29).
• The vault stage has remained relatively constant and negative, indicating no
accumulating water (Fig. 32). However, one incident of zero vault stage was recorded
on 4 August 2023. This incident was caused by a program change made after the
annual calibration and maintenance.
• The voltage sensor that monitors the power supply in the vault is functioning properly
(Fig. 33). The voltage sensor was replaced during the annual calibration and
maintenance on 2 August 2023. The large spikes in voltage shown on 1 August 2023
and 2 August 2023 are artifacts of a new sensor calibration being uploaded to the
software. They are not actual spikes in voltage.
