Annual Technical Evaluation
ofthe
White Mesa Uranium Mill Tailings Management System
For the Period of January 1, 2022 through December 31, 2022
1.0 EVALUATION PROCEDURE
Energy Fuels Resources (USA) Inc. ("EFRI") currently operates the White Mesa Uranium Mill
("Mill") under the Utah Department of Environmental Quality Radioactive Materials License
("RML") Number UT1900479 Amendment #10. The White Mesa Mill Tailings Management
System, Revision 2.5, dated March 2017, (which is section 3.1 of the Mill's Environmental
Protection Manual) provides the methodologies for monitoring and evaluating the Tailings
Management System. Reference documents are listed in the Reference section at the end of this
summary.
RML Amendment 10, dated July 2 7, 2021 included several changes regarding the due date, reporting
period and content requirements for the Annual Technical Evaluation Report ("ATER"). RML
condition 12.2 changed the report due date from December 1 each year to March 1 of the following
year. RML condition 12.2 also changed reporting period from October through the following
November to a calendar year reporting period. RML condition 10.5.F, required the inclusion of the
annual 11 e.(2) annual summary. As a result of these RML changes and direction from DWMRC, this
report covers the time period of January 1 through December 31, 2022.
This ATER satisfies the requirements in RML Condition 12.2 for preparation of an ATER.
This Annual Technical Evaluation was performed on December 27th, 2022, in accordance with the
White Mesa Mill Environmental Protection Manual and consisted of the following elements:
• Review of the Tailings Management System operation and maintenance procedures
and interviews with current site personnel and management to ensure there is an
adequate understanding of the requirements.
• Review of randomly selected daily, weekly, monthly, and quarterly inspection
reports to ensure established procedures are followed and that there are no
irregularities that have not been properly documented.

• Inspection of the area surrounding the tailings facility to determine condition of
diversion ditches. Review of additional peripheral items, such as prairie dog activity,
which could affect the system.
• Review of the survey conducted on Movement Monitors along the boundary dikes,
and comparison of the data to recent surveys.
• Review of the tailings slurry and raffinate piping systems to ensure that their
operation does not have the potential to affect the integrity of the tailings dikes or
liner system.
• Review of maintenance activities in the tailings area that have the potential to affect
the integrity of the tailings dikes or liner system.
• Photographic documentation of the condition of the Cell dikes and surrounding areas.
• Review recommendations provided in previous technical evaluation reports and

White Mesa Uranium Mill
Tailings Management System
February 27, 2023
2.0 OPERA TIO NS
During the period covered by this evaluation, January 1, 2022 through December 31, 2022, the mill
processed 780 tons of Monazite Sands, 1,210 tons of Cameco KF, and 1,764 tons of Cameco
Calcine. During Mill operations various solutions and solids were discharged to the Mill tailings
management system. The solids were discharged to Cell 4A. Cell 1-I ( currently referred to as Cell
1) and Cell 4B were maintained as evaporation cells. Only process solutions and water were sent to
these impounds.
3.0 SITE MANAGEMENT
Mr. Logan Shumway is the current White Mesa Mill Manager. Mr. Shumway has the overall
responsibility to ensure that the Tailings Management System is operated and maintained in
accordance with State of Utah Radioactive Material License No. UT 19004 79. Mr. Garrin Palmer is
the Radiation Safety Officer ("RSO"). Among Mr. Palmer's responsibilities in his current role is the
oversight of day-to-day monitoring and inspecting of the Tailings Management System. Inspections
of the Tailings Management System were performed by trained Mill personnel.
The inspectors are all from the Environmental and Safety Department at the White Mesa Mill. Each
inspector has documentation of recent training on the inspection procedures.
4.0 RECORDS
The mill maintains daily, weekly, monthly, and quarterly inspections for the tailings area. Copies of
the daily and weekly inspection reports for the month of September 2022 are included as a part of
this evaluation. Also, copies of all the monthly inspections and quarterly reports are included as part
of this evaluation. A review of these records was conducted to confirm use of the correct forms,
verify completeness, evaluate content, and to evaluate any unusual events. The Environmental
department appears to be keeping an attentive watch over the tailings area. All records reviewed are
in order and are consistent with the requirements in the Environmental Protection Manual.

5.0 DIVERSION CHANNELS
To the north of the Mill tailings cells there are three diversion channels, which prevent runoff from
flowing into the tailings cells and Mill yard area. Conditions at the time of review are damp with
recent winter storm events. The channels were all clearly visible with small patches of snow present.
Even with the recent precipitation there were not signs of standing water present in any of the
channels. Diversion Channels 1 and 3 had been maintained during the year and had minimal
vegetation. Diversion Channel 2 had not been maintained and had minor vegetation growing in the
channel. There were also signs of minor erosion on the surface. It is recommended that Diversion
Channel 2 be maintained in the spring to ensure the surfaces of it are well maintained.
The South side of the #1 Channel is a constructed berm varying in height from Oto 4 feet. The berm
is in good condition with growing vegetation. There were no significant erosion concerns.
Locations of the diversion ditches are shown in the Mill Site Drainage Basins drawing located in the
Site Photographs section of this document. Photos of the current status of the diversion ditches are
included in the Site Photographs section of this document. At the current time there are no concerns
with functionality or structural stability of the berms and channels.
6.0 TAILINGS DISPOSAL CELLS
6.1 Cell l(a.k.a, Cell I-I)
Cell 1 was the second cell placed into service after being completed in 1981. The Cell was designed
as an evaporation cell for solutions only. No solids are placed into Cell 1. The solution discharged
to the Cell normally comes from the solvent extraction circuit, but solution is periodically pumped
back and forth between Cell 4A, Cell 48, and Cell 1 to maintain required freeboard limits in the
entire system.
Solution freeboard limits for all of the tailings cells are established in Section 3.0 to Appendix D of
the approved license application and confirmed as License Condition 10.3 of the current license. The
Page 6
Annual Technical Evaluation
White Mesa Uranium Mill
Tailings Management System
February 27, 2023
established maximum freeboard limit for Cell 1 is 5615.40 feet above mean sea level ("MSL").
Solution levels did not exceed the maximum freeboard limit during the period evaluated.
Cell 1 has a soil cover over the upper portion of the synthetic liner. The soil serves to cover and
protect the liner from UV coming from direct sunlight. The soil cover was found to be in good
condition. The south side of Cell 1 originally shared a dike with Cell 2. Cell 2 has since been filled
and Phase 1 cover activities were started in April 2016 and were completed in May 2017. The
roadways around the cell are well maintained.
In reviewing the area north of Cell 1 it was found that there are a few signs of prairie dog activity. I
discussed the measures that the Mill Environmental Department is taking to control this activity.
The clearing of vegetation has proven to be effective in reducing the activity near Cell I as well as
being able to identify activity early before the prairie dogs can establish themselves in the area.
They also are doing a good job of closely monitoring the activity and taking action as necessary.
6.2 Cell 2
Cell 2 was the initial tailings cell constructed and was placed into service when the Mill first began
processing ore in 1980. It is no longer receiving any discharge from the mill and has been deemed
full. The surface of Cell 2 has previously been covered with a random fill (platform fill) over the
sands to prevent blowing sands as well as reduce radon emissions. Over the years this has been
added to and adjusted to reduce radon emissions.
In 2016 a revised final cover design was proposed for the tailings cells. Reference "Cell 2
Reclamation Cover Design, Implementation, and Performance Assessment Plan" by MWH. Starting
in April 2016 construction was started to put in place the first phase of the cover design. This work
has been completed. In addition, a test section of the full cover design was constructed in the South-
East comer of Cell 2. This section has instrumentation and equipment to evaluate the performance
of the cover design and will be monitored over the coming years. The test section is officially in
year 3 of a 5-year evaluation period. Data collection has started and will be evaluated for long-term
comparison.

Tailings Management System
February 27, 2023
In order to monitor the consolidation of the tailings sands contained within Cell 2, elevation readings
on settlement monitors are taken monthly. A summary of the settlement monitor elevations is
included with this report along with graphs of the settlement data. Section 7 of this ATER provides
an evaluation of the settlement monitoring results. Photos of the current status ofCell 2 are included
in the Site Photographs section of this document.
6.3 Cell 3
Cell 3 was constructed and placed into service in 1983. It is currently used for disposal of 1 l(e).2
waste materials from in-situ uranium producers and for Mill solid waste and trash. During the
evaluation period process solids from mill operations were not placed in Cell 3.
Approximately 85% of Cell 3 has been covered with random fill. The exposed sands within the cell
have been pushed out and graded. The mill utility crew has continued to place interim cover over
the sands as stability has permitted. The center section of Cell 3 is marked with signs showing areas
designated for lle.2 disposal and mill waste disposal. There is regular activity in these areas.
Sparse vegetation growth is established on the East end of the cell where interim cover has been
placed. The west end has a portion of the phase 1 soil cover placed. The Cell 3 Spillway is in good
condition.
Section 3 .1 of the Environmental Protection Manual establishes the free board limits for the tailings
cells. Cell 2, Cell 3, and Cell 4A do not require freeboard limits as Cell 4B is the final downstream
tailings cell. Solution levels were not taken in Cell 3.
The south dike ofCell 3 is shared with Cell 4A and Cell 4B. The dike crest and all roadways around
the cell are well maintained. Photos of the current status of Cell 3 . are included in the Site
Photographs section of this document.
In order to monitor the consolidation of the tailings sands contained within Cell 3 elevation readings
on settlement monitors are taken monthly. The trending of these readings will be used to determine
Page 8
Annual Technical Evaluation
White Mesa Uranium Mill
Tailings Management System
February 27, 2023
when acceptable consolidation of the tailings sands has occurred. A summary of the settlement
monitor elevations is included with this report along with graphs of the settlement data. Section 7
provides an evaluation of the data collected.
6.4 Cell 4A
Cell 4A was originally constructed in 1989 and placed into service in 1990. Cell 4A was never used
for disposal of tailings material other than process solutions during the first years of its operation.
Cell 4A fell into disrepair and was removed from service in the early 1990's after a brief period of
use. The original 40-mil high-density polyethylene ("HDPE") liner was removed from the Cell as
well as all contaminated materials and soil. The Cell was relined with a new HDPE lining system
beginning in the fall of2007 and finishing in the summer of 2008. The Cell was placed into service
in October of 2008.
The Cell 4A dikes provide containment for current tailings disposal at the White Mesa Mill site. The
east and south dike had been recently maintained and are clear of vegetation or any signs of erosion.
The west dike is shared with Cell 4B. The top surface and roadways on the dikes are all well
maintained.
Cell 4A is the current cell for disposal of solid tailings from mill processing. Sands have been
placed along the northwest side with exposed sands on roughly 30% of the Cell 4A surface.
Solutions fill the remaining capacity. Inspection of the spillway found some degradation of the
concrete around the supports of the pipe bridge. It is recommended that this item be reviewed and
repaired to ensure that the surface integrity of the spillway remains.
Photos of the current status of Cell 4A as well as the spillway are included in the Site Photographs
section of this document.
Section 3 .1 of the Environmental Protection Manual establishes the free board limits for the tailings
cells. The previous freeboard limit of 5,593.74 for Cell 4A is set out in a letter from the Director
dated November 20, 2008. The Director granted a variance from the Cell 4A freeboard limit on
Page 9
Annual Technical Evaluation
White Mesa Uranium Mill
Tailings Management System
February 27, 2023
January 13, 2011 and approved the removal of the Cell 4A limit and the use of Cell 4B on January
27, 2011. The weekly measurements are no longer required for compliance with freeboard limits,
but are required for the calculation of the daily allowable volume of fluids pumped from the Cell 4A
LDS. The freeboard elevation data and charts included in the document reflect the changing levels
within Cell 4A and 4B.
6.5 Cell 4B
Cell 4B was constructed in 2010 and approved for service in 2011. It is currently used only for
solution containment. The cell is lined with the same HDPE system as is installed in Cell 4A. This
cell currently serves as the final collection point for tailings solutions.
Photos of the current status of Cell 4B are included in the Site Photographs section of this document.
The southern dike is the final containment for mill tailings. The south slope has been recently
maintained and there is very little vegetation and no erosion present. The top surface and roadways
on the dikes are all well maintained.
Section 3 .1 of the Environmental Protection Manual establishes the free board limits for the tailings
cells. Cell 2, Cell 3, and Cell 4A do not require freeboard limits as Cell 4B is the final downstream
tailings cell. Cell 4B is set at 5,594.60 FMSL. A review of the records found that there were no
instances of the solution level in Cell 4B exceeding the free board limit during the evaluation period.
In 2022 it was determined that Energy Fuels would cover the bottom surface of Cell4B in order to
provide solution coverage of the crystal formations on the bottom of the cell. Water was generally
pumped continuously into Cell 4B as it was available. Solution was transferred from Cell 4B to Cell
1 as was required to ensure crystal coverage in Cell 1 as well.
6.6 Movement Monuments
The Movement Monuments are placed along the outside boundary dikes in the mill tailings area.
The intent is to survey these monuments yearly and monitor for any movement in the dike. The
current boundary consists of the South Cell 4A dike and the South Cell 4B dike. The evaluated
Page 10
Annual Technical Evaluation
White Mesa Uranium Mill
Tailings Management System
February 27, 2023
year's survey was conducted in May and data has been provided in a report by Cory Smith of Jones
& DeMille Engineering Inc, who is a Utah-Certified Land Surveyor. Review of the survey data in
comparison to surveys from previous years found that the movement monuments are all in good
condition with no notable changes from previous years.
7.0 Settlement Monitors
Settlement monitors are required to be placed on covered tailings cells. Cell 2 has a series of
monitors covering the cell. Cell 3 also has monitors located where cover has been placed over filled
areas. The locations of the monitors are shown on the Settlement Monitor Points drawing included
with the monitoring data. The tracking of the changing elevations of the monitors shows the
settlement or stability of the tailings within the cell.
Elevation surveys of all settlement monitors are taken monthly. The _trend of the data from these
monuments shows the settling or stability of the tailings sands with the exception of monitor Cell 4A
Toe. The Cell 4A Toe monitor does not show any movement or instability at the base of the
southern dike on Cell 4A. Data from this monitor indicate that it is stable. Due to the work being
accomplished on Cell 2 and Cell 3 many of the monitors have had extensions added which can be
seen in the charts by the sudden shifts in the plot lines.
The settlement monitors on Cell 2 have all had extensions added. Pumping of the slimes drain
system in ongoing. Most of the settlement monitors appear to be fairly stable without any significant
settling occurring. There are a few with minor settlement.
The settlement monitors on Cell 3 appear to show mixed trends. The slimes drain system in Cell 3 is
not being pumped as the cell is still active. All settlement monitors appear to be fairly stable over
the evaluation period without any significant settling occurring.
The requirement to place monitors over 1 le.(2) disposal areas was added in 2012. These monitors
are only required to be surveyed once per year. Charts for this data from 2012 to present are
included in this report. The data shows the 11 e.(2) settlement monitors to be stable with no
Page 11
Annual Technical Evaluation
White Mesa Uranium Mill
Tailings Management System
February 27, 2023
significant movement.
8.0 lle.(2) WASTE DISPOSAL
As previously noted, this report satisfies the requirements in RML Condition 10.5.F for preparation
of an annual 1 le.(2) summary document. The annual amounts of byproduct material disposed of
from off-site generators is included as an attachment to this report. There were 4 77 cubic yards of
11 e.(2) waste material received and disposed of during the evaluation period, all of which was
placed in Cell 3. This evaluation included review of documentation and procedures to confirm that
each load of 11 e.(2) material was placed and documented in accordance with the Standard Operating
Procedures for 11 e.(2) Byproduct Disposal. The review confirmed that only materials approved by
the RSO were received and disposed, that each load has been placed, compacted, and covered
consistent with the requirements of the SOP, and that Mill personnel have been documenting each
load consistent with the requirements of the SOP.
9.0 TAILINGS TRANSPORT SYSTEM
The tailings slurries and solutions are transported to the tailings cells via HDPE pipelines. During
mill operation these lines are inspected on a daily basis for leaks or other potential problems. The
tailings solids produced during this period of evaluation were transported to Cell 4A. The pipelines
are run to the interior of the cell such that the discharge does not impact the dikes or cell liner. In
Cell 4A and Cell 4B the pipes are run down "splash pads", which are an added layer ofliner on top
of the standard cell lining.
10.0 CONCLUSIONS AND RECOMMENDATIONS
The White Mesa Uranium Mill Tailings Management System is functioning as designed according to
the routine inspection reports and the observations from this Annual Technical Evaluation. The
inspection records were complete and the personnel involved were adequately trained to detect any
abnormalities or signs of distress in a timely manner. The general condition is very good with all
Page 12

aspects being maintained attentively. The following items should be monitored or addressed:
• Prairie dog activity should continue to be controlled in areas around tailings cells and
diversion channels.
• Diversion Ditch 2 should be cleared and graded at the earliest convenience.
• The Cell 4A spillway should be inspected and repaired to restore the cracked and degrading
surface around the bridge supports.

*The previous freeboard limit of 5,593.74 for Cell 4A is set out in a letter from the Director dated November 20, 2008. The Director granted a variance
from the Cell 4A freeboard limit on January 13, 2011 and approved the removal of the Cell 4A limit and approved the use of Cell 48 on January 27, 2011 .
The weekly measurements are no longer required for compliance with freeboard limts, but are required for the calculation of the daily allowable volume of
fluids pumped from the Cell 4A LOS.
