2009 ANNUAL TAILINGS CELLS WASTEWATER SAMPLING REPORT
1. INTRODUCTION
This is the 2009 Annual Tailings Cells Wastewater Sampling Report for the Denison Mines
(USA) Corp. ("Denison") White Mesa Mill (the "Mill"), as required under Part I.F.9 of the
Mill's State of Utah Groundwater Discharge Permit No. 370004 (the "Permit") and Section 7 of
the Mill's Tailings and Slimes Drain Sampling Program, Revision: 0, November 20, 2008 (the
"Plan").
Tailings and slimes drain sampling is required under the Plan and Part LE.lO of the Permit to be
conducted on an annual basis in August of each year for the solutions in tailings Cells 1, 3 and
4A, the solutions in the slimes drains in Cells 2, 3 (after commencement of dewatering activities)
and 4A, the solutions in the leak detection system in Cell 4A and any detected solutions in the
leak detection systems in Cells 1, 2 and 3. The results of the sampling event are required to be
reported to the State of Utah Department of Environmental Quality ("UDEQ") with the Mill's 3,d
Quarter Groundwater Monitoring Report due December 1 of each year. While tailings and
slimes drain samples have been collected previously, the 2009 sampling described in this Report
is the first to be conducted under the Plan and Permit.
2. SAMPLE EVENTS AND SAMPLING METHODOLOGY
2.1 Sample Events
Samples of solutions from tailings Cells 1, 3 and 4A, the Cell 2 slimes drain and the Cell 4A leak
detection system were collected on August 4, 2009. In addition, a field duplicate for Cell 4A
(FD4A) was collected. Due to an error on the part of the Mill's contract Laboratory relative to
total dissolved solids ("TDS") determinations, Cells 1, 3 and 4A, FD4A and the Cell 2 slimes
drain were re-sampled for TDS on August 31, 2009.
In accordance with the Plan, UDEQ was notified of the sampling event by telephone
conversation, and a UDEQ representative was present at the time of the August 4, 2009 sampling
event.
In addition, fluids were observed in the Cell 2 leak detection systcm. Those fluids were sampled
on August 4, 2009 for the constituents listed on Table 2 of the Permit and for the general
inorganics listed in Part I.E.l (d)(2) of the Permit. The Cell 2 leak detection system was sampled
for semi volatile organic compounds ("SVOC's") on August 10,2009.
The Field Data sheets for the August 4, August 10 and August 31, 2009 sampling events are
included in Attachment A.

2.2 Sampling Methodology, Equipment and ])econtamination Procedures
2.2.1 Tailings Cells
Tailings fluid samples were collected at the tailings cell sampling stations indicated on
Attachment I of the Plan (reproduced as Attachment B to this Report) by extending collection
tubing approximately 6 ft. from the edge of the sampling stations. The tubing was attached to a
horizontal rod and the suction end of the tubing was lowered to approximately 113 of the distance
from the underlying solids and the water surface. This distance was confirmed by sounding prior
to sample collection.
The collection tube was attached to a peristaltic pump and the collection tubing was replaced
anew between sampling locations to assure that the samples were not contaminated by residue
from prior samplings. Accordingly, equipment decontamination was not necessary, and rinsate
samples were not collected, as each tailings sample was provided with fresh inert previously un-
used tubing. Due to the nature of the peristaltic pump. sample fluid does not come in contact
with any surface other than the interior of the sample collection tube.
Samples collected for inorganic analysis were stored in plastic sample containers, provided with
a one inch headspace. Samples collected for volatile organic compounds ("VOCs") and SVOCs
were stored in glass sample containers and were filled in such a manner as to fulfill the zero
heads pace requirement attendant to this analytical regime.
All samples were stored at 6 degrees C or less prior to analyses.
2.2.2 Cell 2 Slimes Drain
The Cell 2 slimes drain was sampled after the slimes drain pump had been operating for a
minimum of 48 hours, in order to assure that the system had been purged and was producing
representative fluids. For the Cell 2 slimes drain, disposable bailers were utilized to collect all
samples, thus eliminating the chance of sample contamination and the need for decontamination
of sampling equipment. Mill staff opted to use disposable bailers rather than the dedicated bailer
concept contemplated by Section 2) of the Plan. Samples for heavy metals and gross alpha were
first stored in a large plastic container and then a peristaltic pump was used to pump the contents
of that container directly into the final sample containers, through a 0.45 micron filter. The
tubing in the pump and the bailers was disposed of and not re-used, thereby eliminating the need
for decontamination of equipment between samples.
Samples collected for inorganic analysis were stored in plastic sample containers, provided with
a one inch heads pace. Samples collected for VOCs and SVOCs were stored in glass sample
containers and were filled in such a manner as to fulfill the 7~ero heads pace requirement.
All samples were stored at 6 degrees C or less prior to analyses.
2
2.2.3 Cell 4A Leak Detection System
For the Cell 4A leak detection system, decontamination was also not required as the samples
were collected directly from the dedicated pump in the leak detection system. Samples for heavy
metals and gross alpha were pumped directly into the final sample containers, through a 0.45
micron filter.
Samples collected for inorganic analysis were stored in plastic sample containers, provided with
a one inch heads pace. Samples collected for VOCs and SVOCs were stored in glass sample
containers and were filled in such a manner as to fulfill the zero heads pace requirement.
All samples were stored at 6 dcgrees C or less prior to analyses.
2.2.4 Cell 2 Leak Detection System
For the Cell 2 leak detection system, disposable bailers were utilized to collect the samples, thus
eliminating the chance of sample contamination and the need for decontamination of sampling
equipment. Mill staff opted for disposable bailers, rather than installing a pump, as contemplated
by Section 3) of the Plan, because the fluids were not deep enough to be pumped. Samples for
heavy metals and gross alpha were fll"St stored in a large plastic container and then a peristaltic
pump was used to pump the contents of that container directly into the final sample containers,
through a 0.45 micron filter. The tubing in the pump and the bailers was disposed of and not re-
used, thereby eliminating the need for decontamination of equipment between samples.
Samples collected for inorganic analysis were stored in plastic sample containers, provided with
a one inch heads pace. Samples collected for VOCs and SVOCs were stored in glass sample
containers and were filled in such a manner as to fulfill the zero heads pace requirement.
All samples were stored at 6 degrees C or less prior to analyses.
The samples were taken within 45 days after the fluids were first detected. Fluid levels in the
Cell 2 leak detection system are minimal, requiring the usc of a bailer for sampling, and have not
increased noticeably since the sampling event. Based on the significant differences between the
chemistry of the water in the Cell 2 leak detection system compared to the solutions in the Cell 2
slimes drain and in the other tailings cells, it is unlikely that the water represents seepage from
Cell 2. Denison is in the process of determining if the fluids are the result of precipitation that
entered through the leak detection system standpipe or are from another source. The Cell 2 leak
detection standpipe is approximately 24 inches in diameter and was uncovered and exposed to
precipitation prior to the time of sampling. Mill staff have since placed a rain-proof cover over
the standpipe.

3. ANALYTICAL RESULTS EVALUATION
All samples were analyzed for all of the constituents in Table 2 of the Permit and general
inorganics listed in Part I.E.! (d)(2)(ii) of the Pennit as well as SVOCs. pH and specific
conductance were also analyzed by the Mill's contract laboratory.
The procedures utilized to conduct these analyses were those utilized for groundwater sampling
and as shown in Section 8.2 of the White Mesa Uranium Mill Ground Water Monitoring Quality
Assurance Plan (QAP), Revision-3, June 18,2008 (the "QAP"). SVOCs were analyzed using
United States Environmental Protection Agency Method 8270.
Reporting limits utilized by the laboratory were required not to exceed the Ground Water Quality
Standards set out in Table 2 of the Permit. For TDS, sulfate and chloride, with respect to which
Ground Water Quality Standards are not set out in Table 2 of the Permit, reporting limits of no
greater than 1,000, 1,000 and 1 mg/L, respectively, were used.
The results of analysis for the August 4 (initial sampling), August 10 (SVOCs in the Cell 2 leak
detection system) and August 31, 2009 (re-sampling of TDS) are provided in Attachments C, D
and E to this Report, respectively. These results are evaluated individually below:
3.1 CellI
Cell 1 solutions were acidic in nature with a laboratory pH of 1.15. As expected, the solutions
contained high concentrations of metals, limited VOC's and, with the exception of Diethyl
Pha1ate, SVOC's were not indicated. Regarding major ions; chloride, magnesium, ammonia,
sodium and sulfate were one to two orders of magnitude greater in concentration than the other
major ions. Metals exhibiting the greatest concentration by at least one order of magnitude
included arsenic, cobalt, copper, iron, manganese, molybdenum, nickel, uranium, vanadium and
zinc. Regarding VOC's, acetone and methylethylketone (MEK) were detected at two orders of
magnitude greater than other detected VOCs. When comparing these data to prior samplings in
1987, 2003, 2007 and 2008, metals exhibited similar characteristics to previous sample results,
with the exception of the 2003 event where nearly all metal values were less concentrated. The
increased presence of acetone and MEK were notable when compared to prior sampling events.
3.2 Cell 3
Cell 3 solutions were acidic in nature, with a laboratory pH of 1.58. These solutions were
dramatically different from prior samplings and from the data observed in Cell 1 fluids. Metals
content was notably absent, with the exception of beryllium, iron, mercury and uranium.
Regarding major ions, chloride, magnesium, ammonia, sodium and sulfate were generally one to
two orders of magnitude greater in eoncentration than the other major ions. With respect to
VOC's, only acetone, chloroform and chloromethane were detected at low concentrations.
SVOC's were not detected. Given the dramatic reduction in metal content over prior sampling,
it appears that these fluids may have been diluted by current process operations.
4
3.3 Cell 4A
Cell 4A solutions were acidic in nature, with a laboratory pH of 1.4. As was the case for Cells I
and 3, Cell 4A fluid exhibited the highest major ion concentrations for chloride, magnesium,
ammonia, sodium and sulfate. For metals, arsenic, copper, iron, manganese, molybdenum,
nickel, uranium, vanadium and zinc were one or more orders of magnitude more concentrated
than the other metals analyzed. Comparison of Cell 4A fluids to those of Cells I and 3 reveals
that Cell 4A is more concentrated in metal content than the 2009 sampling of Cell 3 and similar
(but generally lower in concentration) to those fluids measured in Cell I. As was the case for
Cell 3, VOC presence was limited, with the only measurable compounds being acetone,
chloroform, chloromethane and naphthalene. SVOC's were not detected in Ce1l4A.
3.4 Cell 2 Slimes Drain
Cell 2 Slimes drain fluid was acidic in nature, with a laboratory pH of 3.11. Major ions which
were highest in concentration by one or more orders of magnitude included chloride,
magnesium, ammonia, sodium and sulfate. For metals, arsenic, cobalt, copper, iron, manganese,
nickel, uranium, vanadium and zinc were at least one order of magnitude greater in concentration
than other metals analyzed. It is notable that zinc, nickel, iron, and manganese were greater in
concentration in the Cell 2 slimes drain than they were in the Cell I and Cell 4A tailings
solutions. VOC's were limited to low concentrations of acetone, chloroform, chloromethane,
MEK, naphthalene and tetrahydrofuran. SVOC's were not detected in the Cell 2 slimes drain.
3.5 Cell 3 Slimes Drain
In accordance with Section 2) of the Plan, the slimes drain for Cell 3 is not required to be
sampled until dewatering operations have begun. Cell I is an evaporation pond and does not
have a slimes drain.
3.6 Cell 2 Leak Detection System
Cell 2 leak detection system fluids were near neutral, with a laboratory pH of 6.6. Major ions
were reduced significantly when compared to tailings fluid with higher concentrations noted for
magnesium, sodium and sulfate. For metals, manganese and nickel were the most concentrated
but greatly reduced when compared to tailings solution. VOC's were not measured in excess of
laboratory detection limits. SVOC's were not detected in the Cell 2 leak detection system.
Based on the significant differences between the chemistry of the water in the Cell 2 leak
detection system compared to the Cell 2 slimes drain and the other tailings cells, it is unlikely
that the water represents seepage from Cell 2. Denison is in the process of determining if the
fluids are the result of precipitation that entered through the leak detection system or are from
another source. The Cell 2 leak detection standpipe is approximately 24 inches in diameter and
was uncovered and exposed to precipitation prior to the time of sampling. Mill staff have since
placed a rain-proof cover over the standpipe.
5
3.7 Cells 1 and 3 Leak Detection System
Thc Cells 1 and 3 leak detection systems were not sampled during the 2009 sampling event
because the systems were dry.
3.8 Cell 4A Leak Detection System
Fluids in the Cell 4A leak detection system were acidic in nature with a lab pH of 1.98. The
major ions which exhibited the greatest concentrations included chloride, magnesium, ammonia,
sodium and sulfate. For metals, arsenic, cobalt, copper, iron, manganese, molybdenum, nickel,
uranium, vanadium and zinc were one or more orders of magnitude greater in concentration than
the other metals analyzed. Metals content in these fluids were more concentrated than the Cell 3
tailings fluid. The VOC's acetone, chloromethane, chloroform and MEK were measured at low
concentration. SVOC's were analyzed in the Cell 4A leak detection system and, with the
exception of a trace phenol detection, all were found to be non-detectable in concentration.
3.9 Cell 4A Field Duplicate
A blind duplicate sample was prepared from Cell 4A solutions. A comparative analysis of this
sample against the original Cell 4A sample is discussed under Quality Assurance Evaluation in
Section 6.0 below. It was noted that while the Cell 4A original sample did not indicate the
presence of SVOC's the Field Duplicate indicated trace concentrations of athracene, n-Nitro-di-
n-propylamine and phenanthrene.
3.10 Summary and Conclusions of Analytical Results
The tailings fluids with the greatest concentrations of metals were found to be those in Cell 1.
Cell 3 solutions were anomalously low in concentrations of metals. The metals arsenic, cobalt,
copper, iron, manganese, molybdenum, nickel, uranium, vanadium and zinc were generally
present in greatest concentration for all samples. For major ions, chloride, magnesium,
ammonia, sodium and sulfate were predominant. VOC's with the greatest concentrations in
tailings fluids were acetone, chloroform and chloromethane. With the exception of the
anomalous diethyl phalate measured in Cell 1 tailings fluid, trace phenol detection in the Cell 4A
leak detection system, and trace concentrations of athracene, n-Nitro-di-n-propylamine and
phenanthrene in the Ce1l4A field duplicate, SVOC presence was not indicated.

The results of historical sampling of the tailings cells are provided as Attachment F.
5. QUALITY ASSURANCE EVALUATION
Quality assurance requirements for the annual tailings sampling events include the collection and
QA evaluation of a blind duplicate sample from one of the Cells, a trip blank, and evaluation of
any rinsate samples collected subsequent to equipment decontamination. For this sampling
6
event, a blind duplicate sample was prepared for Cell 4A solutions (FD4A). With regard to
rinsate analyses, the methods employed for this event (disposable bailers and tubing from the
peristaltic pump and a dedicated pump for the Cell 4A leak detection system) did not require
equipment decontamination and subsequent rinsate sampling.
5.1 Duplicate Analyses
As mentioned above a duplicate sample was taken from tailings Cell 4A, which was labeled
sampled FD4A. The results of the duplicate analyses for the 2009 sampling event are provided

The results of the blind duplicate sample analysis demonstrate that with the exception of
chromium and cobalt, major ions and metals analyses fell within the required 20% relative
percent difference ("RPD") requirement. With regard to VOC's, acetone, chloroform,
chloromethane and naphthalene did not comport with the 20% RPD requirement.
5.2 Trip Blank
The trip blank was non-detect for all VOCs, indicating that there were no external influences on
VOCs during sample collection, handling, storage and transportation.
5.3 Laboratol'Y QA
A review of Laboratory QA documentation indicated that RPD values were well within
Laboratory Guidelines. Some matrix spikes (principally for SVOC's) and one lab control sample
were outside of lab guidelines of % Recovery. Further qualification of these samples or the need
for correetive action was not indicated. Also, the initial sampling on August 4, 2009 was
repeated for TDS on August 31, 2009 as the initial sample fell outside of the holding time for
TDS and a re-sample for that parameter was necessary.
5.4 Corrective Actions Required
Due to the non-conforming RPD results identified above, and in accordance with Section 10.2 of
the QAP, the following description and necessary course of corrective action is provided:
a) Identification and definition of the problem
The problem identified is the failure of duplicate analyses to provide an RPD within 20% for
chromium, cobalt, chloroform, chloromethane and napthalene as required by Section 3.2 of the
QAP.
b) Assignment of responsibility for investigating the problem
The problem is being investigated by the QA Manager.
c) Investigation and determination of cause of the problem
In this instance, the field duplicate was collected as a separate sample. Mill personnel alternately
staggered the flow of solutions between the two samples in an attempt to approximate a true
split. However, a true split (i.e., collect one sample into a larger vial and then split it into two
smaller vials) was not attempted because of the requirement to minimize the risk of volatilization
of VOCs and SVOCs during the splitting process. Due to the fact that there will be some
variation between individual samples, in the absence of a true split, this likely resulted in the
8
exceedances of the RPD 20% requirement. For analyses of all constituents other than VOCs and
SVOCs, however, a common container can be used, and true splits can be obtained from the
initial sample.
d) Determination of a corrcctive action to eliminate the problem
For VOC and SVOC analysis, a corrective action is not readily available given the nature of
these zero-headspace samplings. For metals, gross alpha and general inorganics, future samples
will be collected into a large container and split samples of those categories of constituents will
be obtained from this common sample source.
e) Assigning and accepting responsibility for implementing the corrective action
It will be the responsibility of the RSO and sampling technicians to implement fhe corrective
action.
f) Implementing the corrective action and evaluating its effectiveness
Implementation of the corrective action will occur during the 2010 sampling event, and its
effectiveness will be evaluated once these samples have been collected and analyzed.
g) Verifying that the corrective action has eliminated the problem
Verification that the corrective action has eliminated the problem will occur subsequent to the
receipt of sample results for the 2010 sampling event.

Project: Annual Tailings CASE NARRATIVE
Sample Delivery Group: C09080228
REVISEDISUPPLEMENTAL REPORT
The attached analytical report has been revised from a previously submitted report due to a request on December 1,2009
for the correction of the Total Xylene report limit to the requested 1.0 uglL for this project. The data supports this correction,
and this revised report reflects this update. The report has also been revised for the addition of Conductivity on samples -001
through -007. The data presented here reflects that additional analysis.
BRANCH LABORATORY SUBCONTRACT ANALYSIS
Tests Associated with Analyst identified as ELI-B were subcontracted to Energy Laboratories Billings Branch, EPA Number
MT00005.
ORIGINAL SAMPLE SUBMITIAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4'C (t2'C)
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 USING EPA 505
Data for Atrazine and Simazine are reported from EPA 525.2, not from EPA 505. Data reported by ELI using EPA method
505 reflects the results for seven individual Aroclors. When the results for all seven are NO (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 qualffied contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.
