TFN 5 1/330, RESTORATION RESEARCH PROJECTS., T3 REVIEW

PERMIT 633, CAMECO RESOURCES

Cameco submitted responses to T2 review comments to LQD in a letter dated November 1, 2012discussing three proposed research projects including a tracer study, a bio-stimulation study, anda natural attenuation study. A revised proposal dated October 29, 2012 was provided outliningactivities to conduct for the tracer and bio-stimulation studies with letter. The natural attenuationstudy was deferred to a later date under a future proposal.

Below are the 11 comments from LQD reviewed as not acceptable from the T3 review andresponses from Cameco.

Tracer Study Proposal

9 Response Not Acceptable. The map Mine Unit 4 Bio-Remediation Proposed Test Wellsindicates two five spot patterns that will be used for the bio-remediation test proposal. Thankyou for the map. The response indicates the map is attachment 1, however, this reference wasnot identified on the map. LQD would prefer the map be included in the Reclamation Plan.Please insert the map into the Reclamation Plan and provide a text reference to the map on page6-3H. (PCR)

Cameco Response: The attached Index of Change includes text reference on page 6-3H and themap is part of the insertion with the Restoration Research Project (revised June, 2013).

13 Response Not Acceptable. CR states that monitoring is not planned. The test is expectedto last one to two years without pumping to maintain an inward gradient. Please explain how apotential excursion will be detected. The LQD would expect to have the tracer mass remediatedwith a demonstration of the remediation to achieve restoration of the Mine Unit. (See Comment11 below) (PCR)

Cameco Response: Cameco monitors for potential excursions in this part of Mine Unit 4 on a60-day sampling schedule frequency using monitor wells M-415 through M-423. Excursionmonitoring will continue during the study tests while the Mine Unit is in restoration. The tracertest does not change the potential for any lixiviant movement especially since the header house#6 pattern areas have completed the pore volume of groundwater sweep and RO treatment. As tothe remediation of the injected tracer, it should be noted that the groundwater proposed for tracerstudies was not classed as potable before mining was done and is unlikely to be so afterrestoration. The tracers proposed for use in this study have been used in Nevada groundwaterdesignated as potable, and regulators in that arid state did not require the tracer to be recovered atthe conclusion of testing. Cameco believes that further reverse osmosis treatment of the watersto which tracers have been added may be counter-productive and should only be undertaken inthe unlikely event that water quality is seriously degraded by the carefully controlled applicationof a bio-stimulant. Cameco proposes that the metrics for determining water quality degradationin the aftermath of the project would be statistically significant increases in such species such as


uranium, radium-226, selenium, arsenic and bicarbonate (the latter tends to mobilize uranium).Statistical significance would be established by comparing WDEQ guideline 8 water chemistrydata in the bio-stimulated area to that in neighboring patterns. Since the tracers have not beenremoved after use in potable water in Nevada, they would not figure in the decision as to whetherreverse osmosis treatment is needed at the conclusion of the project if this proposal.

20 Response Not Acceptable. The LQD would expect to have the tracer mass remediatedwith a demonstration of the remediation to achieve restoration of the Mine Unit. (PCR)

Cameco Response: Please see the response to point 19. The concern here is that additionalreverse osmosis treatment done after the project is completed, solely for the purpose ofremoving tracers, might actually reverse a successful restoration of the pattern by removingboth ORP and pH buffering capacity and by lowering the total dissolved solids concentrationto the point that the water becomes more aggressive as an agent for dissolving minerals.Cameco shares the LQD desire for as thorough a restoration as possible, and we respectfullysuggest that end may (or may not) be served by additional reverse osmosis treatment.

22 Response Not Acceptable. The proposal when approved will need to be incorporatedinto the permit. CR may wish to request a separate confidential volume to be kept in a lockedcabinet. The request should be in writing and well justified for a determination by theAdministrator (WEQA §35-11-1101). Any future monitoring reports and the final report will bemaintained in this volume. Please update the index of change to indicate how the revision willbe maintained in the permit. (PCR)

Cameco Response: Cameco will not need to request a confidential file. The project researchactivities will be conducted by professional groups outside of Cameco and will prepare reportsfor peer review. Reports shared with Cameco may have temporary conditions to keep theinformation confidential until the peer review is published. When the proposal is approved, theresearch activities will be authorized under the permit. Cameco proposes to create a new volumeV titled "Research/Investigation Projects" where approved plans/proposals will be placed asauthorized activities on permit 633. Monitoring and final reports generated from authorizedprojects can be maintained in the volume as appropriate. The attached updated Index of Changeindicates the designation of a new volume for the permit.

23 Response Not Acceptable. An estimated cost should be provided for the infrastructure,groundwater restoration and disposal costs needed for the project. CR does not anticipate"clogging" of the restoration wells due to biorestoration as occurred in MU-C in 2009,

however, a maintenance cost to swab and or a replacement cost for the wells is needed as aprecaution. Monitoring and sampling costs should be included as needed to demonstrateexcursion prevention and restoration of the injected constituents. Drill holes used for coresshould be identified in the surety. LQD understands the cost will be minimal, however over theduration of the project a cost will be incurred. It is suggested that a section of the suretyidentified as Restoration Research Proposal be added with a breakdown of the identified costs.(PCR)


Cameco Response: As discussed in a meeting with LQD on June 20, 2013, reclamation costsfor the proposal will be identified in the updated surety estimate for Mine Unit 4/4A. The studiesinvolved are not necessary for reclamation; moreover, costs associated with outside services arenot part of the bonding for permit 633. The updated surety that will be submitted with the 2012-2013 Annual Report will identify reclamation costs for anticipated core drilling, added wells, andpossible well replacements. As discussed, a pore volume of groundwater treatment will bemaintained (kept on the surety) for when the field work is terminated if groundwater treatment isdeemed necessary. Mine Unit 4/A is scheduled to reach stability monitoring in 2018 at whichtime all groundwater restoration will be completed.

26 Response Not Acceptable. The steps are well defined with approximate time periods forthe individual steps included for the tracer and nutrient additions. It appears the project couldtake a minimum of one year and up to two years to complete with a final evaluation and reporttime period in addition to the one to two years of field testing. The monitoring and samplingscheduled are undefined. LQD will expect to be updated with the data on a routine schedule.Please provide a commitment to update the LQD with the information that will be provided.This commitment should be included on page 6-3H of the Reclamation Plan. (PCR)

Cameco Response: Cameco will provide LQD with reports generated and provided from theresearch groups involved. A routine schedule for updated data will be determined once the fieldstudies are underway. The attached Index of Change contains a revised page 6-3H that shows thecommitment in bolded text.

Bio-Stimulation Proposal

8 Response Not Acceptable: The map Mine Unit 4 Bio-Remediation Proposed TestWells indicates two five spot patterns that will be used for the bio-remediation test proposal.Thank you for the map. The response indicates the map is Attachment 1, however, this referencewas not identified on the map. LQD would prefer the map be included in the Reclamation Plan.Please insert the map into the Reclamation Plan and provide a text reference to the map on page6-3H. (PCR)

Cameco Response: See response to Comment 9 under the Tracer Study Review.

I Response Not Acceptable: The response better defines the reason that monitoring willnot be provided (compared to the response to Comment 13 above). CR could expand thediscussion in Section 2.1.6 with language included in the response to justify the lack ofmonitoring. Further explanation to the revision text could also better define the lack of need toprovide remediation of the tracers and nutrients added to the pattern areas. CR should considerexpanding the discussion in Section 2.1.6 for a determination of an acceptable response toComments 13 (Tracers) and Comment 11 (Bio-restoration). (PCR)

Cameco Response: Contained in the attached Index of Change is a revised proposal tosupersede previous submitted proposals for insertion into Volume V upon approval. Section


2.1.6 has been expanded and text rewritten to address Comment 13 (Tracers) and this comment.The text changes are in bold font.

13 Response Not Acceptable: The proposal when approved will need to be incorporatedinto the permit. CR may wish to request a separate confidential volume to be kept in a lockedcabinet. The request should be in writing and well justified for a determination by theAdministrator (WEQA § 35-11-1101). Any future monitoring reports and the final report will bemaintained in this volume. Please update the index of change to indicate how the approvedrevision will be maintained in the permit.

Cameco Response: See response to Comment 22 under the Tracer Study Review.

14 Response Not Acceptable: An estimated cost should be provided for the infrastructureand disposal costs needed for the project. CR does not anticipate "clogging" of restorationwells due to bio-restoration as occurred in MU-C in 2009, however, a maintenance cost to swaband or a replacement cost for the wells is needed as a precaution. Monitoring and samplingcosts should be included as needed to demonstrate excursion prevention and restoration of theinjected constituents. Drill holes used for cores should be identified in the surety. LQDunderstands the cost will be minimal, however over the duration of the project a cost will beincurred.

SUBJECT: PROPOSAL TO CONDUCT RESTORATION RESEARCH PROJECTS(revised, June, 2013)

1. INTRODUCTION

1.1 This letter is a formal request for permission to conduct two field research experimentsfor the evaluation of promising techniques that may improve restoration methods atSmith Ranch and in the in situ recovery (ISR) mining industry in general. The specificexperiments are: 1) tracer tests to determine the hydrologic pathways between injectorand recovery wells; and 2) bio-stimulation tests to determine the viability of usingnaturally-occurring bacteria to re-precipitate uranium and other redox-sensitive species.A third experiment described in the first draft of this proposal as a natural attenuation testto determine the ability of the aquifer down gradient of the mining zone to immobilizecontaminants has been deferred. The deferral was necessary because mining began in thearea where the test was to be conducted. These tightly controlled experiments will beconducted on an extremely small scale and if successful will provide supporting data fora request to alter the allowed permit restoration methods. It is important to emphasizethat no alteration in mine restoration methods or schedules as currently described in ourpermits will be done without regulatory approval.

1.2 Tracer studies to elucidate the flow patterns between injector and producer wells willaddress questions concerning hydrologic sweep efficiency during restoration. Theoptimization of sweep offers much promise for improving all restoration processesirrespective of whether they employ bio-stimulation, ground water sweep, reverseosmosis treatment, or the addition of inorganic chemical reductants such as sodiumsulfide. A bio-stimulation project was conducted at Smith Ranch from April toNovember of 2009. An analysis of the data resulting from that project concluded thathydrologic sweep was a major factor in limiting the efficacy of the bio-stimulation. Toour knowledge, there are no tracer studies in the scientific or public record that examinesthe issue of injector/producer well flow patterns during restoration at an ISR mine.

1.3 In recent years, the scientific literature has contained many reports on the restoration ofground water containing uranium and other heavy metals. Contaminated ground waterand solids at Department of Energy (DOE) test sites at Oak Ridge, Tennessee; Hanford,Washington; and Rifle, Colorado have been treated with organic nutrients in an effort tostimulate the growth of native bacteria that can precipitate uranium and other heavymetals.(1-4). We know of no such studies at an ISR mine.

1.4 The natural attenuation of radioisotope contamination (including uranium) has beeninvestigated at the Savannah River, South Carolina DOE facility and appears to beproceeding on a time scale of decades (5). We are not aware of any data that sheds light

Proposal to Conduct Restoration Research ProjectsPage 2 of 12October 29, 2012

on the time-scale of natural attenuation processes in the aftermath of ISR mining inWyoming as well as the mobility of various ions in the aquifer.

1.5 Systematic investigations at Smith Ranch might identify improvements in the restorationprocess here that could decrease the required time to restore and minimize theconsumptive use of water (i.e., water that must be sent to disposal). The DOE studiescited in the preceding paragraphs involve ground water that often has radically differentgeochemistry from that encountered in the ISR mining industry. Furthermore, ISRaquifers are often considerably deeper below the surface of the ground and therefore lesssusceptible to periodic oxygen contamination from an influx of surface water orprecipitation.

2. PROPOSED PROJECT DESCRIPTIONS

Descriptions of both of the projects follow. While there are obviously inter-relationshipsbetween them, it is hoped that each will be treated as a separate proposal by the DEQ. Inprincipal, the bio-stimulation project could be done without tracer work. However, thetracer studies would add much to our understanding of the efficiency with which bio-stimulants can be added to patterns as well as providing clues as to how the hydrologicand mineralogical changes that may occur as a result of bacteriological action impactrestoration.

2.1 Study #1, Tracer Study:

2.1.1 Understanding the flow patterns between injector and recovery wells is a central issuein the restoration process. This study will involve the use of a different tracer foreach injector well in a pattern, so that the degree of hydrologic connection betweenindividual injectors and the producer is quantified. The tracers will be used to studythe same two patterns in header house 4-6 (centered on recovery wells 4P-121 and4P-1 13) that are discussed in the bio-stimulation narrative (study #2) below.Injection of the tracers will be done using wells 41-213/214/217/218 for the case of4P-121 and wells 41-201/202/206/207 for the case of 4P- 113. (See MAP, AttachmentI)

2.1.2 Tracers will be added to injection streams in header house 4-6 using a peristalticpump capable of delivering tracer solution at the required flow rate. A tracer will beadded to only one injector at a time rather than simultaneous introduction to all fourinjectors within the pattern. A mini-header for doing this has already beenconstructed in the header house and tested with the peristaltic pump (using water).The mini-header completely isolates the wells receiving injection from all other wellsin the header house, so tracer cannot inadvertently be introduced to wells for which itis not intended. Injection will be done by metering a concentrated tracer solution outof a 40 or 50 liter carboy into the injection line for a given injector. The tracersolution flow rate will be adjusted so that the solution accounts for no more than I to2% of the total injection flow into the well. This will be done to avoid density-drivenflow effects that might occur in the aquifer if the tracer solution were injected at a


higher flow rate or as a single concentrated slug. The injection of each tracer solutionis expected to take I to 2 hours. After all the tracer solution is injected into one well,another tracer solution (containing a different tracer) from another carboy will bemetered into another injector, and so on, until all four injectors have received tracer.The water produced from the single production well in the 5-spot pattern will bedirectly routed to the mini-header that will feed the injectors in equal proportions toinsure pattern balance. In other words, during the test the produced flow will be re-injected into the same pattern from which it came without being sent to the satellite.Sampling will be accomplished by continuously drawing a low-flow-rate stream fromthe production flow and routing it to an automated sampler. This stream will flow atno more than about 50 mL per hour, which is negligible compared to the expectedproduction flow rate of about 25 gallons per minute (-5500 liters per hour). Note thatno other wells in header house 4-6 or the neighboring header house 4-5 will be onduring the research projects.

2.1.3 Multiple tracers will be used so that the flow from each injection well can beindependently traced for at least one pass through the flow system. This will providethe information necessary to estimate flow porosity, swept volume, and sweepefficiency between each injector and the common producer in a 5-spot pattern, thusproviding four times more information than would be the case if the same tracer wereintroduced into each injector. It is important to obtain this information because if asingle tracer was injected into all the injection wells, one would not be able todistinguish whether the tracer breakthrough curve at the producer represents an equalcontribution from each injector or sequential contributions from different injectors (asthe two extremes of an infinite number of possibilities). With different tracersintroduced to each injector a much more complete and less uncertain picture of theflow heterogeneity in the pattern will emerge. This more complete picture can beused to make operation adjustments to distribute bio-stimulant more efficientlythroughout the pattern during the bio-stimulation test. In a more general sense, thismore complete picture of flow heterogeneity in a couple of representative patternswill also help in estimating or predicting how effective different restoration strategieswill be.

2.1.4 It may be instructive to compare pump tests (typically done here at Smith Ranch)with tracer tests. Pump tests can provide good information on permeability andstorativity of aquifers, including reasonable information on directional permeabilityand permeability distributions when there are several observation wells. However,pump tests do not provide good information on effective flow porosity, sweptvolume, or sweep efficiency between injection and production wells, particularlywhen both injectors and producers are active. These are the most importantparameters dictating both uranium recovery efficiency during mining operations andefficiency in delivering remediants (e.g., biostimulants, inorganic reductants) duringrestoration operations. The tracer tests are designed to provide much more direct andactive operational conditions than pump tests can provide. The oil and gas industryhas used inter-well tracer tests for decades to evaluate these operational parameters,recognizing that pump tests provide very uncertain estimates of these parameters.


2.1.5 It is anticipated that about 5 kilograms of each of up to six tracers will be required fora test in a given pattern, and tracers tests will be run before bio-stimulation and(possibly) after bio-stimulation on at least one of the two patterns (and possibly both).Laboratory studies using core and ground water samples taken from the patterncentered on 4P-121 will be conducted at Los Alamos National Laboratory (LANL) toidentify tracer molecules that will not interact appreciably with the aquifer solids.There are two families of molecules from which the tracers will be chosen: 1)fluorinated benzoates, and 2) halides (bromide or iodide). The fluorinated benzoatesand halides have been used to study a number of water sources of economicsignificance, including an aquifer in southern Nevada that has significant commercialand residential importance (6-7). For the case of that aquifer, they were used as partof the Yucca Mountain Site Characterization Project. Approximately 50% of theinjected mass of tracers was recovered in the Nevada project, though not because ofenvironmental concerns about leaving them in the water. The nature of theexperiments was such that an inject-and-pump protocol was necessary for dataanalysis purposes. Even the tracer pumped to the surface was discharged on theground where it (presumably) re-infiltrated into an aquifer. Given the arid nature ofNevada and that state's contentious relationship with the Department of Energy, it isnoteworthy that the use of these tracers was never challenged.

2.1.6 Cameco monitors for potential excursions in this part of Mine Unit 4 on a 60-daysampling schedule frequency using monitor wells M-415 through M-423.Excursion monitoring will continue during the tracer and bio-stimulation studytests while the Mine Unit is in restoration. Monitoring for tracers outside theproposed patterns will be done periodically (once every other month) to identifyany migration. If groundwater restoration is needed to remove the tracers afterthe bio-stimulation test, groundwater treatment can be used to remove most of theremaining tracer from the patterns (more than 90%). The brine stream from thereverse osmosis unit would be routed for disposal to one or more deep disposal wells.The degradation product(s) from the action of a diverse microbial community on thetracers is difficult to predict, but it should be pointed out that organic molecules arenot expected to be long-lived compared to the inorganic species routinely sent to deepdisposal.

2.1.7 Included with this submission are Material Safety Data Sheets for tracer chemicalsthat have been evaluated to use in the field tests. The tracer chemicals are Sodium2,4-Difluorobenzoate (Attachment 2), Sodium 2,5-Diflourobenzoate (Attachment 3),Sodium 2,6-Difluorobenzoate (Attachment 4), Sodium 2,6-Diflourobenzoate 20%Solution (Attachment 5), Sodium 2,3,4,5,6-Pentafluoroenzoate (Attachment 6),Sodium 2-Fluorobenzoate (Attachment 7), Sodium Bromide (Attachment 8), andSodium Iodide (Attachment 9). It should be noted that Dr. Reimus has used thesetracers without incident in plumbing made of a wide variety of materials, includingcarbon and stainless steel, PVC, and polyethylene. The IX columns at Smith Ranchare made of carbon steel, the header house manifolds are composed of PVC, otherpiping is made of High Density Polyethylene, and some fittings are stainless steel or


carbon steel. There are no plumbing components that would be affected by any of thetracers proposed for use here. The major cationic solutes in the ground water wherethe test will be done are calcium and magnesium with a lesser amount of sodium.Major anionic solutes include total alkalinity (virtually all in the form of bicarbonate),chloride, and sulfate with much a much smaller amount of uranyl dicarbonate species(a great deal of which is complexed with calcium). Nothing in solution in the water isexpected to react with the tracers. It is more likely the tracers will interact with thetarget formation mineralogy than with the fluids or groundwater constituents. Thefluorinated benzoates might interact with organic compounds present in the aquifersolids, and in fact, some weak interaction between has been observed in a laboratorycolumn experiment conducted using some of the core material obtained near well 4P-121. Four of the fluorinated benzoates listed above were selected for the field testbecause they exhibited the least amount of interaction with the core material of the sixfluorinated benzoates that were evaluated in the column experiment. Iodide, whichexhibited no interaction with the core material, will be co-injected with 2,5-difluorobenzoate, which showed the greatest interaction, so that the degree ofinteraction in the field tests can be directly assessed. We anticipate less interaction ofthe fluorinated benzoates in the field than in the laboratory experiment because webelieve the organic material in the laboratory experiment was over-representedrelative to what tracers will experience in the field. That is because volumescontaining heavier concentrations of organic matter are less likely to be permeablethan other areas. Since the mineralogy has already been heavily oxidized by themining process that lasted for years, it is difficult to envisage a few tens of kilogramsof tracer (used in potable water source aquifers at other locations) applied over a shortperiod of time having any discernible impact on aquifer characteristics. Guideline 8results for samples collected earlier this year for wells 4P-113 and 4P-121 areattached to this proposal as Attachment 10 and Attachment II respectively. Becausethere are no known reactions between the chemical species in the water and thefluorinated benzoate tracers and interactions with the solids are weak, there is notlikely to be any impact on CR's ability to restore the aquifer to baseline conditions.

2.1.8 It will be informative to conduct a tracer test in a mine unit before mining begins.Such tests could be used in conjunction with core studies to examine the influencethat changes in mineralogy that accompany production and restoration have on flowpatterns.

2.1.9 The timeline and steps for the tracer and bio-stimulation work is as follows:

a. Selection of test patterns - completedb. Tracer selection based on laboratory testing - completedc. Tracer analytical method development/verification and deployment of High

Performance Liquid Chromatography (HIPLC) system at Smith Ranch for onsitetracer analysis - completed (HPLC was taken back to Los Alamos because ofdelays but can easily be returned to the mine site)

d. Tracer procurement and delivery at Smith Ranch - completede. Injection of tracers into one pattern - one day


f. Injection of tracers into second pattern - one additional dayg. Development of tracer breakthrough curves (i.e., collection of samples and onsite

analysis of samples as water is circulated through the patterns) - estimated to beone month after tracer injection, but exact time will depend on results

h. Completion of tracer analyses of samples (filling in gaps, re-running samples thatdo not satisfy quality control checks) - one month after field test is completed(note that pattern circulation may continue after breakthrough curves are fullydeveloped, in which case samples will continue to be taken at low frequency)

i. Initiation of bio-stimulation tests in the patterns - could be started after step g ifready. This is the step where nutrient is added to the patterns. Nutrient additionis estimated to take approximately four months, and laboratory column testsconducted Professor Willford will refine this estimate.

j. Post-stimulation monitoring should be done for at least another 6 to 8 months (bio-stimulation and monitoring together are estimated to take about a year). Duringthis period, the two patterns would not be pumped except to take periodic samplesfor the purpose of monitoring changes in geochemical conditions.

k. Repeat of steps of steps d through h after bio-stimulation to determine changes inflow pathways within patterns due the bio-processes - 2 additional months but notinitiated until after bio-stimulation is assessed, which could be several months.

-I. Optional reverse osmosis treatment of test patterns and adjacent pathways torecover tracers and bio-stimulants - started after bio-stimulation test is deemedcomplete and lasting a month or more depending on tracer concentrationsproduced over time (we would not to treat with RO sweep until after bio-stimulation testing is completed and evaluation of the effectiveness of the bio-stimulation is evaluated).'

2.2 Study #2, bio-stimulation:

2.2.1 The bio-stimulation efforts reported in the scientific literature have had varyingdegrees of success, but all have been conducted in environments unlike thatencountered at an ISR uranium mine. A key difference between the ISR case and thebio-stimulation efforts at DOE sites is the depth of the contaminated water. At theDOE sites, contaminated waters are much closer to the ground surface than is the caseat ISR mines. ISR aquifers should be easier to sequester from atmospheric oxygenand might therefore be more amenable to restoration using bio-stimulation techniquesthan is the case for shallower waters.

2.2.2 The proposed bio-stimulation study will be done on two patterns in header house 4-6(see Map, Attachment 1). These are not contiguous and will encompass recoverywells 4P-121 and 4P-113 and their associated injectors 41-213/214/217/218 for thecase of 4P-121 and 41-201/202/206/207 for 4P-113). The patterns will be runsequentially so that only one pattern will be on at any given time to avoid theintermixing of water between them. A line will be installed connecting theproduction manifold in the header house to the injection manifold so that theproduction stream will re-circulate back to the injectors. Note that re-circulating thestream between a recovery well and injectors has been done on several occasions in


the past without incident. Re-circulation ensures that oxygen contamination is kept toa minimum since the recovery fluids are no longer being sent to a satellite plantwhere storage in surface tanks can expose them to the atmosphere. Because thisproject is operating on such a small scale (the two patterns used for bio-stimulationencompass only about 20,000 square feet of surface area), a small peristaltic pumpwill be used to precisely meter nutrient into the injectors. Nutrient transport would begauged by performing the tracer tests described in the proposal for that portion of theproject. Nutrient concentrations (and possibly metabolic byproducts of the nutrient)can also be monitored at the producer well in each pattern and at the monitor well inpattern P121 either as total organic carbon or via a more molecule-specific approachusing High Performance Liquid Chromatography.

2.2.3 See paragraph 2.1.9 in the tracer test narrative for the combined time line of the tracerand bio-stimulation projects.

2.2.4 Mine unit 4 was mined from 1999 to 2006. Some of the wells in this mine unit arecompleted in two zones, but header house 4-6 has only single-completion wells.Since 4-6 restoration activities began in late 2010, one pore volume of ground watersweep has been completed in that header house, and this was followed by XX porevolumes of reverse osmosis treatment. The two patterns to be used in the testing arepresently not being pumped. Attached to this document are Guideline 8determinations done on samples taken from these two patterns in the spring of 2012(Attachments 10 & 11). The nutrient chosen will be an electron donor, so speciessuch as ferric oxy-hydroxides, sulfate, and uranium (VI) may be reduced. Theseprocesses would likely result in increased ferrous iron and sulfide concentrations inthe aquifer waters (both of these are desirable Oxidation-Reduction Potential buffersin a restored aquifer). If the reduction of uranium (VI) does occur, the solubleuranium would precipitate from solution thus decreasing concentrations of this metalin the ground water. Preliminary column experiments performed by Professor JohnWillford of the University of Wyoming indicate that aqueous uranium concentrationssignificantly decrease within 30 days of the start of nutrient addition using tryptone (aprotein derived from dairy) as the nutrient. Professor Willford is willing to discusshis column experiments with LQD representatives in a face-to-face meeting if theLQD desires such a conversation.

2.2.5 The choice and quantity of organic nutrient used will be determined in consultationwith experts such as Drs. John Willford and Peter Stahl of the University ofWyoming and Dr. Kate Campbell of the United States Geological Survey (USGS). Aconsulting environmental firm, Shaw Environmental, Inc., conducted a previousstudy to evaluate the efficacy of organic nutrients specific for the Smith Ranch-Highlands (SRH) site in 2004. That study tested I 1 potential bio-stimulants on minecore sediment and well field ground water obtained from SRH. Cheese whey andsafflower oil in an ethanol solution showed the most extensive reduction of solubleuranium. It is noteworthy that the cheese whey produced more rapid bio-reduction,but both of these nutrients showed potential to be effective bio-stimulants.Subsequent use of cheese whey in Mine Unit C showed that injector well clogging


was a problem, though the clogging was easily removed by swabbing the well bore(this completely restored injection flows). The bio-nutrient chosen for this project willbe either safflower oil or tryptone, the latter being an enzymatic digest of casein.Tryptone advantages include: a) it has the same protein sources as cheese whey(casein), b) it is more highly refined and completely soluble in water to at least a 2%concentration (which is ten times the concentration proposed for the field project), c)it has a high nitrogen content amongst available peptones, and d) it provides thehighest iron content for a milk-derived peptone. Iron was included as a factor as ithas been demonstrated that Fe(lll)-reducing microbes play a significant role in thereduction of U(VI). Preliminary laboratory results obtained by Professor JohnWillford of the University of Wyoming indicate that tryptone is more effective thansafflower oil in alcohol solution for decreasing soluble uranium concentrations, sosubsequent discussions of bio-remediation in this document will focus upon the use oftryptone as the bio-stimulant.

2.2.6 A core was taken approximately mid-way between in 41-218 and 4P-121 (see theattached map referenced in the preceding paragraph), and samples of it along with theground water have been sent to the University of Wyoming for microcosm testing.The core was examined by a field geologist immediately after being taken so that acore description could be obtained. It was then cut into sections that wereindividually vacuum-sealed in plastic and labeled before being catalogued andshipped for laboratory work. The core was shipped in insulated containers kept coolwith either water ice or dry ice. The hole from which the core was taken was thengamma-logged. Mineralogical comparisons will be made with core results from ourlibrary of samples taken in other mine units. Any data involving uraniummineralization is only valid if obtained from fresh core, but studies of clays withincores, elemental composition (not including oxygen or hydrogen), ion exchangecapacity, and pyrite mineralization are likely to be useful in core that is stored inplastic sleeves at ambient temperature and, in the case of pyrite, dry conditions. Nocore library samples will be used for micro-biological work.

2.2.7 The hole from whence the core was taken has been cased and will be used as apassive sampling point if this proposal is approved. Passive water sampling issampling that is done without the disruption of flow patterns within the aquifer, and apassive sampling point is the location at which a passive sample is taken. One formof passive sampling (the type likely to be used in this research) involves the use of avessel dropped into the well that opens down hole in the waters to be sampled ratherthan the usual method done at SRH, which requires a motorized pump to extractsample water. Another method of passive sampling involves the use of diffusionmembranes to capture chemical species of interest. Such sampling is NOT beingproposed here for environmental compliance samples, but would be employed onlyfor samples taken for scientific purposes. The validity of such sampling would beestablished through scientific peer review both by the University of Wyoming Schoolof Energy and reviewers at scientific journals to which manuscripts resulting fromthis work would be submitted. Please note that this well is covered by surety bondand was approved by the state engineer's office.


2.2.8 The flow from each individual injector will be measured, as will the pressure in theheader house injection manifold. A down hole sensor will be used to monitor pH,Oxidation-Reduction Potential (ORP), and conductivity. The readings for theseparameters will be logged and stored at periodic intervals. Samples will be drawn ona regular schedule for the determination of concentrations of such chemical species asdissolved uranium, total alkalinity, chloride, dissolved and total iron, selenium, andarsenic. The data should provide a detailed picture of the chemical evolution of thebio-stimulated volume of aquifer.

2.2.9 Past bio-stimulation efforts at Smith Ranch have resulted in well-clogging, and this isthe biggest pitfall foreseen in the project. Such clogging can impede the uniformdelivery of nutrient to all of the pattern pore volume and thus limit the effectivenessof the stimulation. In the case of Mine Unit C, the clogging did impair the efficacy ofthe bio-remediation because nutrient was not delivered to significant portions of theaquifer. The eight injectors involved in this project (far fewer than was the case forMine Unit C) could be swabbed and cleaned within a matter of days to removeclogging. The proper selection of a nutrient will hopefully minimize or eliminate theclogging problem. Injector/producer flows and injector pressures must be carefullymonitored to insure that clogging is caught early so that nutrient delivery is asuniform as possible. That is why continual data logging of flows and pressures anddaily examination of the resulting data is so important. Given that the impactedpatterns represent less than halfa percent of the mine area currently under restoration(and a far smaller percentage of the total mine site), there will be no impact on therestoration schedule for the site even if the wells clog.

2.2.10 In addition to the field work, laboratory studies of the core will be undertaken tocharacterize the post-mining mineralization of the aquifer solids. There are manypre-mining core samples available in the Smith Ranch core library, and themineralization of these can be compared to that in the post-mining 4P-121 solids.Mineralization will be studied by a contingent of researchers that will include Dr.Reimus, Dr. Tanya Gallegos of the USGS, Cameco scientists at the company's PortHope, Ontario research centre, and the Universities of Wyoming and California atBerkeley (working through or with Dr. Reimus). The taking of a post bio-stimulationcore is also planned so that changes in mineralization caused by biological activitycan be observed.

2.2.11 An attempt will be made to characterize the bacterial populations present in the post-mining core material. Dr. Campbell will study DNA markers and Dr. Willford willexamine Phospholipid-derived fatty acids obtained from the core. The hope here is toshed light on which bacterial species at Smith Ranch might act to precipitate uraniumand other heavy metals. Dr. Kevin Chamberlain and co-workers at the University ofWyoming will study U23 8 /U 23 5 and C13/C12 isotope ratios in water samples to look forclues as to whether these ratios are changed via the metabolic pathways of micro-organisms within the restoration zone. They will also look at these isotopic ratios inwater samples taken from the natural attenuation study.


2.3 Study #3, natural attenuation and contaminant mobility:

Mine Unit K North has been brought into production, so the natural attenuation studyproposed in this first draft of this proposal will be postponed until a later mine unit isbrought into production (hopefully next year). When a suitable new location is chosen,CR will submit a proposal for the project.

3. CONCLUSION

3.1 It should be emphasized that these projects are not a request for a change in therestoration processes described in our permits. If approved, they will be part of aresearch effort that might someday result in a request for change in the restorationprocess at Smith Ranch.

3.2 A key feature of the proposed projects is the small area that will be used. The twopatterns in header house 4-6 that will be involved in the bio-stimulation effort constituteless than 2% of Mine Unit 4 (two patterns out of 130 in the unit) and will be monitored inreal time for changes in flow rates or injection pressure that will signal the onset of wellclogging. Because of the miniscule portion of the mine unit involved in the test,adjusting the mine unit restoration schedule is unnecessary. The natural attenuation studywill take place in an area that is already approved for mining (Mine Unit K north) and isunlikely to have any discernable impact on mining or subsequent restoration activities.The tracer studies are of a standard variety that has been done in many places, andresidual concentrations of the tracer compounds will be largely removed by subsequentreverse osmosis treatment of the tracer-tagged waters.

3.3 It is our hope that the three studies described in this document can be treated as separateproposals so that regulatory decisions as to whether they can proceed can be made on anindividual basis. The summer and early autumn months offer obvious advantages forconducting field research, and allowing even a single study to proceed early (particularlytracer work) will be of great value. Research activities will begin immediately afterreceiving regulatory approval with bio-stimulation and natural attenuation studiesfollowing the tracer tests. Some aspects of the field work will end with the onset of coldweather in the autumn, but sampling of the bio-stimulation patterns will continue wellinto the winter.

3.4 The Land Quality Division comments on the first draft of these proposals contained thestatement concerning the bio-stimulation project (LQD comment #10) and the tracerproject (LQD comment #12): "Please explain in the revision the reason for conductingthe research proposal on the permitted mine sites and whether they could be conductedelsewhere under a Research and Development license. (PCR)". We propose to do all ofthese projects on this site because any advancement in restoration technology is expectedto be site-specific. The geochemical and hydrologic conditions at Smith Ranch aredifferent from those at other locations, so the most efficient way to investigate restorationimprovements at Smith Ranch is to conduct the research at the Smith Ranch site. In

Proposal to Conduct Restoration Research ProjectsPage I I of 12October 29, 2012

conversations with CR in the recent past, LQD has declaimed that restoration techniquesused at our Crow Butte, Nebraska mine may not work at Smith Ranch because ofdifferences in local conditions. CR shares this concern and proposes to address the issuewith an onsite project. It might also be mentioned here that a significant portion of thefunding for this research is being provided by the School of Energy at the University ofWyoming and was awarded after a careful scientific peer review of submitted proposals.That funding devolves from the state legislature, and we think it reasonable to supposethat legislators wanted to pay for research that investigates the possibility of improvingrestoration processes at Wyoming's largest ISR uranium mine and by extension other ISRmines that are or will be operating within the state. Furthermore, laboratory experiments,while useful, must be advanced to field testing to gain more knowledge. As to obtaininga Research and Development license, we would point out that previous testing was doneat Smith Ranch without it. After reading the regulations that govern the issuance of R&Dlicenses, we are not sure that such a license is applicable to the project we propose. Iffurther examination of this issue indicates that pursuing such a license is appropriate, CRwill do so.

3.5 The objective of these projects is to provide information that will allow us to improve theground water restoration process at Smith Ranch. Peer-reviewed scientific publicationsor other reports peer-reviewed by qualified scientists at the University of WyomingSchool of Energy or regulatory agencies will provide a mechanism for the lessons learnedfrom these projects to be made widely available to regulators and other uranium miners.A portion of the research described here is being funded by a grant from the Wyominglegislature that is being administered by the School of Energy Resources at the Universityof Wyoming. Additional funding is being provided by the Departments of Energy andthe Interior, and CR is providing logistical support and drilling services for the work aswell as a $25,000 grant to researchers at the University of Wyoming. The largecomponent of state and federal government funding for these projects strengthens theircredibility, and the expertise of these researchers offers regulators and miners alike a rareopportunity to look for ways to improve ground water restoration processes at an ISRmine in Wyoming.
