Re: State of Utah Radioactive Material License No. UT 1900479
April 27,2011 Amendment Request to Process an Alternate Feed Material
from Dawn Mining Company
Transmittal of Supplementary Information
Dear Mr Lundberg
This letter is a follow-up to Utah Division of Radiation Control's ("DRC's") meeting vsdth Energy Fuels
Resources (USA) Inc ("EFRI") on November 8, 2012 regarding our April 27, 2011 Amendment Request for
a proposed altemate feed from dewatenng of Water Treatment Plant ("WTP") solids from Davm Mining
Company's Midmte Mine As we discussed at that meeting, since the submittal of the Amendment Request,
Dawn Mining Company evaluated the use of a filter press as an altemative to the centnfiige presently in use
for dewatenng the WTP solids
EFRI IS providing a copy of the Filter Press Pilot Testing Report, Midnite Mine (the "Testing Report")
prepared by Advanced Environmental Sciences, Inc. for Dawn Mimng Company
Basis of Amendment Request
As discussed at the November 8, 2012 meeting, EFRI uses highly conservative assumptions when assessing
the impacts of the constituents of any altemate feed on the Mill process, the tailings system or the
environment. The April 27, 2012 Amendment Request performed all calculations of concentrations, and all
estimates of quantities for approval, on a dry weight basis, that is, based on 100 percent solids
Results of the Dewatering Pilot Test
As discussed in the Amendment Request, the solids are currently dewatered via a centrifuge and have
averaged approximately 15 percent solids. It was anticipated by Dawn Mining, and discussed in Section 2 2
of the Amendment Request, that use of the filter press could possibly reduce the volume to be shipped by
increasing the solids content to a value between approximately 25 and 45 percent solids The four samples
from six tests runs produced filtered solid product ranging from 59 3 to 65 4 percent moisture (40 7 to 34 6
percent solids) The Testing Report has concluded that 35 percent solids content is, in fact, achievable with
the proposed equipment

Quantity to Be Shipped to the Mill
The primary effect of the proposed use of a filter press in lieu of the current centrifuge vdll be to reduce the
volume of water in the matenal to be shipped to the Mill. However, the quantity of material for which EFRI
sought approval in Section 2 3 of the Amendment Request was not based on a volume, but was expressed as
a mass in dry tons of solids Since the dry tons of solids will not change, regardless of how much bound
water is or is not shipped with the solids, the quantity requested for approval has not changed.
Chemical Analysis of Filter Press Cake
As we explained dunng the November 8, 2012 meeting, the filter press pilot test is a physical process that
added no chemical constituents, and would be expected to change the WTP matenal only in water content
Results of laboratory analyses on the filter press solids are provided in Appendix A of the attached report As
were the results reported and used in the Amendment request, the results from the post-pilot test analyses
were reported on a dry weight basis The results indicated that:
• Consistent with the data reported in the Amendment request, all RCRA metals analyzed for TCLP
remained non-detectable at a detection limit an order of magmtude below their respective TCLP
standards
• The uramum content, on a dry weight basis, was within the levels reported and used in the
Amendment Request
• The contents of all other radionuclides, on a dry weight basis, were within the levels reported and
used in the Amendment Request
RCRA Assessment, Process Safety, Environmental and Tailings Impact Assessment
The Amendment Request used analytical data reported on a dry weight basis, as did the attachments to the
Testing Report. As mentioned above, all analyzed constituents reported in the Testing Report were within
the ranges reported and used in the RCPLA Assessment (Attachment 4), and the Process Safety,
Environmental, and Tailings Impact Assessment (Attachment 5) of the April 27, 2011 Amendment Request.
Conclusions
The additional analyses support the conclusions in the amendment request that
• The uranium matenal does not possess a RCRA charactenstic
• The uramum matenal is not and does not contain RCRA listed waste
• The radiological composition of the uramum matenal falls vdthin the ranges of other altemate feed
matenals and ores previously handled and processed at the Mill
• The chemical composition of the uranium material falls within the ranges of other altemate feed
matenals and ores previously handled and processed at the Mill
• The assumptions and basis of the Amendment request was sufficiently conservative to be unaffected
by the findings of the Testing Report

1.0 INTRODUCTION
Pilot-scale filter press testing was performed from September 16 through September 23, 2011, at
the Midmte Mine water treatment plant (WTP) The purpose of the filter press testing was to
determine the filter cake percent solids, sludge volume reduction, polymer addition, press cycle
time, and ease of press cleaning In addition, laboratory analyses (Energy Laboratories) were run
on the filter cake for total uranium (dry weight), total radium-226/228. Thorium 230, density, and
Toxicity Characteristic Leaching Procedure (TCLP) RCRA 8 metals A description of the testing and
the results are presented m the following sections

2.0 EXISTING AND PROPOSED SLUDGE HANDLING FACILITIES
The WTP produces a semi-solid sludge that is disposed offsite The sludge is currently trucked to
Dawn Mining Company's (DMC) Ford millsite for disposal in a lined tailing pond (TDA-4) in
accordance with the Residual Management Plan (Miller Geotechnical Consultants, Inc, 2011)
In the future, the disposal location may change from TDA-4 which will require trucking of the
sludge over greater distances to non-DMC owed disposal facilities In order to reduce trucking and
disposal costs, technologies to reduce the sludge volume are being investigated by DMC
2.1 Current Centrifuge System
Currently, sludge from clarifier #1 is fed to a steady head tank and then pumped to a centrifuge for
dewatering Historically, sludge from the centrifuges has had a laboratory analyzed percent solids
of between 14 percent and 16 percent
Based on DMC reported sludge volumes from 2001 through 2009, the WTP produced a total of
approximately 252,000 cubic feet of sludge from the centrifuges Using the historic WTP operating
schedule of 4 days per week, 4 weeks per month, and 5 months per year, this equates to
approximately 350 cubic feet of sludge produced per operatmg day A summary of the historic
WTP treatment rates and sludge production is contained in Table 1 0
2.2 Proposed Filter Press and Bench-Scale Testing
Dawn Mining Company has proposed to install a filter press (Advanced Environmental Sciences,
Inc, 2010) to reduce the sludge volume that must be trucked and disposed The proposed filter
press system is a plate and frame system, incorporates a membrane squeeze, and is sized for 50
cubic feet per cycle
In june 2010, a dewatenng test was performed on the WTP sludge using a bench-scale plate and
frame filter press The bench-scale filter press consisted of a center feed plate with a filter cloth and
outer plate on each side of the center plate The sludge slurry was fed to the center plate at
approximately 80 psi and the filtrate exited through the outer plates The test indicated that the
sludge dewatered well and released from the filter cloth easily Laboratory analyses of the sludge
indicated percent solids of approximately 19 percent
Based on the bench-scale testing, previous experience with lime treatment sludge, and information
from the filter press manufacturer it was estimated that a ftill-scale filter press with a membrane
squeeze would produce sludge with percent solids content in excess of 30 percent
Questions were raised by the Environmental Protection Agency (EPA) on the accuracy of the
percent solids estimate, sizing of the sludge steady head tank, and number of press cycles per day
(EPA, 2010 and 2011) In order to provide additional information to EPA, a pilot-scale filter press
was leased and operated and the resulting filter cake analj^ed, as described in the following
sections

3.0 PILOT-SCALE FILTER PRESS TESTING
Pilot testing was performed from September 16 through September 23, 2011 The pilot system was
setup inside the WTP, near the sand filters For the first three days the press was setup and
plumbed and the last day the press was decontaminated and packed for shipping Actual testing
occurred from September 19 through September 22,2011
A model 470mm pilot press was leased from Micronics, Inc Pictures 1 and 2 show the press setup
The pilot press consisted of three molded polypropylene membrane plates and head and tail plates
The two chambers between the three membrane plates were utilized to produce the filter cake for
testing The pilot press consisted of the following
Each plate chamber was approximately 342 square inches with an approximate filled depth
of 1.3 inches (prior to membrane squeeze)
Finely woven synthetic blend filter cloth between plates
Polyethylene sludge steady head tank with a low angle cone bottom on a metal stand The
tank diameter was 42 inches
Air diaphragm pump used for sludge feed to the press Maximum pump output of 100
pounds per square inch (psi)
Air driven piston pump for bladder pressurization using water Regulated pump output of
210 psi
4500 psi hydraulic closing pressure using a manual hydraulic pump
Air blow system regulated at 40 psi

Picture 2 Filter Press
The typical sequence of pilot operation consisted of closing the press, filling the press,
pressurization of the membrane squeeze, and then blow down of the press The pilot press was
operated in batch modes and the filling, membrane squeeze, and air blow durations were varied
during testing Initial testing indicated that additional flocculant, beyond that used in the treatment
process, was not required and none was added during pilot testing For all tests, the filter cake
released easily and cleanly from the filter cloth In addition, for all tests that used the membrane
squeeze, no free water was observed and the cake was extremely competent, in some cases
requiring a screwdriver to break up
In addition to laboratory analyses, field determination of percent dry solids was performed using a
Seiko Moisture Anal5rzer, model DSH-50-10 The solids were heated to approximately 105 degrees
Celsius and the heat was maintained until no further weight loss was automatically determined by
the analyzer The unit gave a read-out of dried weight, percent dry solids, and percent moisture
loss The anal)^er was used as general screening instrument for onsite dry solids determination
and the results were higher than the laboratory analyses The difference in analyses between the
Seiko anal5^er and the laboratory results is due to the much longer drying time specified by the
laboratory analytical method The Seiko anal5^er is shown on Picture 3

The following sections describe the pilot tests performed The sludge steady head tank was filled
one time for tests #l-#5, in order to maintain the same feed solids consistency During these first
five tests, the sludge was kept suspended through mixing The feed solids had average solids of 14
percent (field measured) For Test #6, the steady head tank was filled with fresh feed solids, which
had average solids of 11 5 percent (field measured) Table 2 presents a summary of the operational
parameters for all six tests
3.1 Pilot Test #1
Pilot Test #1 was performed on September 16, 2011 For this test, the press was filled fairly quickly
to the maximum 100 psi pump stall pressure The pressure dropped to 80 psi over approximately 5
minutes The membrane squeeze was then initiated and the pressure brought up to 200 psi over
approximately 7 minutes and held at 200 psi for 20 additional minutes The air blow down was
operated at 40 psi for 10 minutes
Field solids determination showed variation between approximately 43 and 49 percent, depending
on where the sample was obtained from the filter cake Near the edges of the filter cake, the solids
varied from 46 0 to 48 8 percent Two samples from the middle of the filter cake had a range of
44 3 to 43 4 percent dry solids No samples from this test were submitted for laboratory analyses
Pilot Press Report November 1,2011
Midmte Mine Filter Press 5 Revision 0
3.2 Pilot Test #2
For Test #2, the press was filled slowly over 35 minutes until the pump stalled at 100 psi After
press filling, the membrane squeeze was slowly brought up to 210 psi over 65 minutes and then left
at that pressure for an additional 40 minutes After the membrane squeeze, the air blow down was
run at 40 psi for 10 minutes
Two samples were field analyzed and one sample was submitted for laboratory analyses The field
analyses indicated percent solids of 53 6 and 52 1 percent The laboratory analysis reported
percent solids of 36 5 Table 3 summarizes the field and laboratory analyses
3.3 Pilot Test #3
This test was operated in a similar manner to Test #1 in that the press was filled fairly quickly
(ISminutes) to the 100 psi pump stall and the membrane squeeze was brought to 210 psi over a
relatively short time frame of 15 minutes Similar to Test #1, the air blow down was operated at 40
psi for 10 minutes The major difference between this test and Test #1 is that the membrane
squeeze was left pressurized for 40 minutes during this test and for only 20 minutes during Test
#1
Two samples from this test were field analyzed and one sample was submitted for laboratory
analyses The field analyses indicated percent dry solids of 54 4 and 514 percent For this test, the
laboratory analysis had the solids at 34 6 percent Table 3 summarizes the field and laboratory
analyses
3.4 Pilot Test #4
Test #4 did not utilize the membrane squeeze operation of the pilot press This test was performed
to allow a comparison of the filter cake dewatenng, with and without the membrane squeeze
function
This test was operated by filling the press over 45 minutes and allowing the pump to essentially
dead head for an additional 15 minutes During this test, the air blow down was run at 40 psi for 10
minutes
Field analyses of two samples indicated percent solids of 33 0 and 30 5 percent Do to the lower
percentage of solids for this test, a sample was not submitted for laboratory analyses
Picture 4 shows filter cake from Test #3 (right) and Test #4 As can be seen m the figure and as
field anal5^ed, the cake from Test #3 is drier and has approximately one-half the volume of the
filter cake from Test #4 For Test #3, the filter cake had a measured thickness of 1 3/8 inches while
the cake for Test #4 was almost twice as thick at 2 5/8 inches

3.5 Pilot Test #5
For Test #5, the press was filled slowly over 45 minutes until the pump stalled at 100 psi After
press filling, the membrane squeeze was slowly brought up to 210 psi over 60 minutes and then left
at that pressure for an additional 60 minutes The air blow down was run at 40 psi for 20 minutes
Two samples were field anal5^ed and one sample was submitted for laboratory analyses The field
analyses indicated percent solids of 54 0 and 55 1 percent The laboratory analyzed sample had a
percent solids of 40 7 Table 3 summarizes the field and laboratory analyses
3.6 Pilot Test #6
Test #6 was run using similar operational parameters to Test #2, except that fresh feed solids were
used The feed solids used for this test were field measured at approximately 2 5 percent less than
for Test #2
For this test, the press was filled slowly over 30-35 minutes until the pump stalled at 100 psi The
membrane squeeze was slowly brought up to 210 psi over approximately 65 minutes and then left
at 210 psi for an additional 40 minutes After the membrane squeeze, the air blow down was run at
40 psi for 10 minutes

Revision 0
Field analysis of two samples resulted in percent solids of 47 3 and 48 2 percent One sample was
submitted for laboratory analyses The laboratory analyses determined a percent solids of 35 9 for
this sample Table 3 summarizes the field and laboratory analyses
The dry solids percentage from this test was slightiy lower than for Test #2, even though both tests
were operated in a similar manner The lower percentage of solids from this test may be due to the
lower percentage of feed solids or there may have been some solids thickening/consolidation in the
steady head tank for Test #2

Midmte Mine Filter Press 8 Revision 0
4.0 LABORATORY ANALYSES
Four test samples were submitted to Energy Laboratories for analyses of percent moisture, density,
TCLP RCRA 8 metals, total uranium (dry weight), and total radionuclides consisting of radium-
226/228, Thorium 230 As shown on Table 3 0, the moisture content of the samples ranged from
59 3 percent to 65 4 percent Density of the samples ranged from a low of 116 grams per cubic
centimeter (g/cc) to a high of 1 34 g/cc
TCLP results showed that all the RCRA 8 metals were not detected at an order of magnitude below
their respective standards The total dry weight uranium concentrations ranged from 8210 to 9980
milligrams per kilogram Radium 228 was <0 2 picocuries per gram (pCi/g) (dry) and radium 226
ranged from 0 07 to 0 2 pCi/g (dry) Thorium 230 had elevated detection limits due to matrix
interferences and for three of the samples was not detected at less than <3 2 pCi/g (dry) One
sample had thorium detected at 2 7 pCi/g (dry)

Midmte Mine Filter Press 9 Revision 0
5.0 SUMMARY AND CONCLUSIONS
A total of SIX filter-press pilot tests were performed from September 19 through 22, 2011
Operational parameters including the fill cycle, membrane squeeze cycle, and blow down cycles
were varied during the tests Flocculant addition was not added or needed during pilot testing For
all tests, the filter cake released easily and cleanly from the press filter cloth
Four of the six tests were laboratory analyzed for percent moisture and all six tests were analj^zed
for percent moisture in the field using the Seiko analyzer Test #1 had the lowest fill pressure and
shortest duration membrane squeeze resulting in the lowest field measured percent solids of the
tests in which the membrane cycle was used Test #4 had the lowest field measured percent solids
due to the membrane squeeze cycle not be used The laboratory analyzed percentage solids for
Tests #2, 3, 5, and 6 were similar with Test #5 having the driest cake (40 7 percent solids) Test #5
had the longest fill and membrane cycle resulting in the driest cake
Based on the filter press pilot test results, greater than 35 percent dry solids is achievable using a
plate and frame filter press with a membrane squeeze component Forty percent or higher dry
solids may be achievable depending on the duration of the filling and membrane squeeze cycles
