Dear Ms. Tischler:
SUBJECT: December 2, 2011 DUSA Letter, 2011 Surety Update;
Revised Surety Estimate Approval: Radioactive Materials License UT 1900479
The Division ofRadiation Control (DRC) received the December 2, 2011 DUSA letter which provides a
revised suiety estimate. This revised surety estimate provides for larger quantities of conventional ore and
altemate feed material to be stored on site through March 2012, with a corresponding cost increase. The ^
DRC has reviewed this information, and hereby approves this Revised Surety Estimate update in the
amount of $19,420,335 as submitted by the DUSA December 2, 2011 letter.
This updated estimate is a $92,077 increase from the recently approved DUSA estirnate of $19,328,258
dated November 1, 2011. This updated estimate is designated by DUSA as White Mesa Uranium Mill
Reclamation Cost Estimate, December 2011, Revision 4.7.
Information supplied in the December 2, 2011 estimate show a projected storage inventory of 100,000 toils
of conventional ore and 18,146 tons of alternate feedstock for a total of 118,146 tons. This represents an
net decrease of 71,795 tons, from the 2010 projected inventory estimate of 189,941 tons. The License for
the facility limits the total conventional ore and altemate feedstock inventory in storage to the estimated
amounts covered by the approved surety (Condition 10.I.D). The attached sheets summarize the cost and
ore inventory changes.
Our previous surety estimate approval letter of November 15, 2011 requested a surety instrument based on
the previously approved figure. However, that estimate amount is superseded by this updated surety
estimate approval. Therefore, we request you do not submit a surety instrument based on the previously
approved figure.
However, in accordance with VAC R313-24-4 (10 CFR 40, Appendix A, Criteria 9 as incorporated by
refeience). you must submit a replacement surety instrument consistent with this latest approved surety
estimate amount of $19,420,335. Condition 9.5 of the License requires you to submit corresponding
written evidence of an adequate surety within 30-days of receipt of this letter.

SUBJECT: November 1, 2011 DUSA Letter, Response to September 14, 2011 DRC Letter, Request
for Information; March 4, 2011 DUSA Letter Submitting a 2011 Surety Update-
Estimate Approval: Radioactive Materials License UT 1900479
The Division of Radiation Control (DRC) received the subject November 1, 2011 DUSA letter which
provided a revised surety estimate. The DRC has reviewed this information, and has no further inquiries.
Therefore, the DRC approves the Surety Estimate update in the amount of $19,328,258 as submitted in
the subject DUSA November 1, 2011 letter.
This updated estimate constitutes a $550,870 increase from the previous approved surety amount of
$18,777,388. The increase was mainly due to the adjustment in costs for the slimes drain evaporation
pond liner, machinery mobilization and operating costs, technician labor hours, and corresponding
increases due to costs tied to percentage multipliers.
The latest approved surety estimate is included in the subject DUSA November 1, 2011 letter. This
estimate is designated as a total revision to Attachment C to Revision 3.2-Final of the approved White
Mesa Mill Reclamation Plan, and should replace Attachment C in its entirety. The estimate summary is
also designated by DUSA as Revision 4.5, October 2011.
We have enclosed two summarizing spreadsheets, our 2009-2010 Reclamation Cost Estimate Comparison
Review Summary as well as our 2011 Conventional Ore and Altemate Feedstock Inventory Estimate, per
DUSA Supplied Volumes. The License for the facility limits the total conventional ore and altemate
feedstock inventory in storage to the estimated amounts covered by the approved surety (Condition
lO.l.D).
Information supplied in the March 4, 2011 and November 1, 2011 estimates show a projected storage
inventory of 31,000 tons of conventional ore and 29,085 tons of altemate feedstock for a total of 60,085
tons. This represents a decrease of 129,856 tons, from the 2010 projected inventory estimate of 189,941
tons.

As you are aware, a performance assessment study on the tailings pond cover system titled the Denison
Mines (USA) Corp. Infiltration and Contamination Transport Modeling Report, White Mesa Mill Site,
Blanding, Utah is under review by the Division. Additionally, a license renewal application was received
by the DRC in February 2007, and is cunently under agency review and out for public comment. The
review of the reclamation plan is an important part of this process. Based on the final outcome of the
study, the license renewal process, and review of the reclamation plan, the surety may need to be adjusted
separately from the normal annual renewal sequence.
In accordance with UAC R313-24-4 (10 CFR 40, Appendix A, Criteria 9 as incorporated by reference), you
must submit a replacement surety instrument consistent with this surety estimate approval. Condition 9.5
of the License requires you to submit corresponding written evidence of an adequate surety within 30-days
of receipt of this letter. If you have any questions, please contact Mr. Rupp at [phone].

March 4, 2011 DUSA Letter Submitting 2011 Surety Update;
Retraction of NOED, Apology, Comments and Request for Information
The subject DUSA letter of March 4, 2011, submitting the DUSA 2011 Surety Estimate
Update.
June 28, 2011 DRC Letter regarding non-submittal of surety estimate, containing a Notice
of Enforcement Discretion (NOED). T
July 1, 2011 DUSA Letter regarding non-submittal of surety estimate.
DEQ received the subject DUSA letter, reference (a), dated March 4, 2011. This letter was not received by
DRC staff. Therefore DRC issued reference (b) in this regard. However, this letter was somehow
misplaced by DEQ in its mail routing system. When DUSA became aware of this error, reference (c) was
sent to DRC, to replace the missing original submittal.
Therefore, DRC hereby retracts reference (b), as the routing documents show that reference (a) was
actually delivered to the Department of Environmental Quality, but was somehow misplaced. We also
apologize for this error.
We have reviewed the subject letter, and have the following comments:
1. General Comment: Haul routes and times are sometimes referred to in various sections of the
estimate. Please provide a detailed table and maps,- which describe the haul routes, the haul route
numbers, distances, materials, and the total round trip haul times, which include the loading and
unloading times, for the various routes and materials to be transported. Adjust any affected costs
resulting from the new table values.
2. Mill Decommissioning Section. The "Conventional Ore Disposal" table in this section estimates
the stockpiled weight of the ore on site at 100 lbs. /cubic foot. This seems to be a low weight for

the conventional ore we have observed stockpiled on site. Please document the current average
stockpiled weight of the conventional ore on site, and apply this value in the "Conventional Ore
Disposal" portion of the estimate.
3. Cell 1 Section.
In the table of the title "Place Lower Random Fill" in this section, scraper, compactor, D8
dozer, and D7 dozer operator labor costs have been omitted in the portion of the table
provided. Please provide completed missing information for review.
4. Cell 2 Section.
a. The table of the title "Upper Random Fill" in this section, the table does not provide
operator labor costs for most of the power equipment operators. Please include the
missing information in the table.
b. A table of the title, "Rock Armor and Rip Rap Filter in this section, did not provide the
extended labor operation costs for the D7 dozer, waterwagon and motorgrader operators.
Please include these missing labor costs in this table.
5. Cell 3 Section.
a. The table of the title "Clay Layer" in this section does not have the operator labor costs
shown for most of the power equipment operators. Please include the missing information
in the table.
b. The table of the title "Upper Random Fill" in this section, as submitted, did not provide
operator labor costs for most of the power equipment operators. Please include the
missing information in the table.
c. A table of the title, "Rock Armor and Rip Rap Filter in this section, did not provide the
extended labor costs for the dozer, waterwagon and motorgrader operators. Please include
these missing labor costs in this table.
6. Miscellaneous Section.
a. In the Slimes Drain Evaporation Pond table, a 960,000 square foot pond is contemplated.
However, there is no budget for equipment or labor to install the liner, per se. That is the
equipment and labor to roll out, cut, seam, trim, patch, weld, and test the Hner. Please
include this cost in the estimate.
b. Equipment Mobilization Table and the "Equipment Costs" Spread Sheet:
(i) . The "Equipment Costs" spread sheet, under the primary Mob/Demob column, do
not list the corresponding current freight charges, as shown in "Attachment A" of
the Feb. 16, 2011 letter from NCRL Leasing. This appears to total $348,850.
(ii) . The "Equipment Costs" spread sheet. The "Mobilization" cost for maintenance
support personnel is $35,600 each way for a total of $71,200, per the Feb. 16, 2011
letter from NCRL Leasing. This cost, and the amount from the above item, total
$420,050. This sum should appear on the first line of the Equipment Mobilization
Table, in the miscellaneous section of the estimate.
c. In the Management Support table, there are two line items, one for a part-time
Environmental Technician and one for Environmental Monitoring Lab Costs. In addition
to these budgeted amounts for environmental monitoring, the total should include any
separate unique monitoring costs required by the Annual Technical Evaluation Report
(ATER), the tailings cell dewatering elevations, surface water elevations and freeboard
monitoring as required by the DMT and BAT O&M plans, and other unique monitoring
outlined section 2.3 of approved Reclamation Plan 3.2. A single part-time technician will
Page 3
be unable to perform all of these tasks without assistance. Please breakdown these costs to
demonstrate that all these monitoring costs (including all necessary technician labor hours)
are covered in the surety estimate.
Please review the above comments, and submit the requested information, including a final summary of the
adjusted costs. Per your email on September 13, 2011, you committed that DUSA would fully .respond to
the above within 45 calendar-days of receipt of this letter. If you have any questions on the above, please

Re: October 15, 2010 DUSA Response Letter to September 23, 2010 DRC Request for Information; March
3, 2010 DUSA Letter.r2;010 Surety Update; Request for Information
Dear Mr. Lundberg:
We are responding to the November 16, 2010 Request for Information from Dave Rupp asking for additional
clarification on the October 2010 update, Revision 4.3, of the White Mesa Mill reclamation cost estimates. Mr.
Rupp's comments are restated below, in italics, followed by our response. Where necessary, replacement
pages are provided for inclusion in the March, August and October 2010 estimates. These revisions are
labeled Revision 4.4, and also include the estimated cost for reclamation of tailings Cell 4B, that was submitted
as Revision 3.2 in June 2010.
A. Equipment Maintenance Hourly Rate. The fixed monthly equipment maintenance cost of $65,430
provided by North Central Rental and Leasing (NCRL) is exclusively for the machinery rentedfrom
NCRL. The subject DUSA letter of March 3, 2010, has an Equipment Costs tab. An Equipment
Costs spread sheet is provided under that tab. The first table in that spread sheet shows a list of
NCRL equipment hours totaling 2,992 hours per month Thus, the hourly rate for maintenance of
the NCRL equipment would be $65,430/2,992 hours or $21.87per hour:
However, DUSA used a figure of $20.57 per hour for the maintenance in the subject submittal of
October 15. 2010, The figure of $65, 430for NCRL equipment plus $759/monthfor corresponding
foel monthly was divided by 3,218 hours. The 3,218 hours are an additional 226 hours greater
than the 2,992 hours mentioned in the paragraph above. Please explain the use of 3,218 hours for
the NCRI. equipment rather than the 2,992 hours.
The 2,992 hours were increased by approximately 7.5% to take into account the likely excess hours operated
during each month of the project. This would result in additional hours covered by the maintenance agreement.
Letter to Mr. Rusty Lundberg
November 23, 2010
Page 2
In discussions with Dave Rupp it became apparent that this approach would possibly cause confusion in
understanding the overall hourly operating cost. Therefore the total hours used to calculate the hourly
maintenance charge has been reduced to 2,992. Copies of the estimate summaries affected by this change
have been attached to this letter as revision 4.4. Future estimates will be modified to include the likelihood of
construction equipment operating overtime, or a second shift, each month.
B. Please assure the following items are included in the current surety estimate:
(1) . The truck shop/barrel painting building south of the main entry road.
Costs have been included for demolition of the truck shop / barrel painting building under the Mill
Decommissioning section. Copies of the estimate summaries affected by this change have been attached to
this letter as revision 4.4.
(2) . The electrical/maintenance storage building just north of the ore sample storage building.
Costs have already been included for the Sample Plant Building. The additional building in question is actually
a temporary structure used for material storage. Costs have been included for demolition of the temporary
storage building under the Mill Decommissioning section. Copies of the estimate summaries affected by this
change have been attached to this letter as revision 4.4. J
Please contact the undersigned if you have any questions or require any further information.

Dear Ms. Tischler:
SUBJECT: March 3, 2010 DUSA Letter, 2010 Surety Update;
Request for Information
We received the subject letter from DUSA which conveyed the 2010 surety update titled Revised
Cost Estimates for Reclamation of the White Mesa Mill and Tailings Management System, dated
March 2010. We have reviewed this information and have the following comments:
1. Equipment Maintenance. The Equipment Costs spread sheet with the subtitle White
Mesa Mill Reclamation Costs, shows that the hourly rate for equipment maintenance
dropped from $21.15 per hour in the 2009 estimate to $20.53 per hour in the 2010
estimate. The calculation method to derive the hourly maintenance rate for 2010 is
unclear.
a. Please explain and justify the derivation of the hourly equipment maintenance rate
for 2010, or
b. Correct the hourly maintenance cost for this estimate.
2. Tankage and Spare Parts Removal. On page 4 of the Mill Decommissioning portion of
the estimate. Misc. Tankage and Spare Parts Removal costs are shown in a table titled
the same. Per DUSA's previous surety letter of October 5, 2009, this table includes
only the reclamation of the newly constructed uranium and vanadium SX feed tanks
and the SX raffinate tank. However, the reclamation of all the other existing tank
systems at the mill appears to be omitted from the March 3, 2010 estimate.
Please demonstrate that the reclamation of all the existing tank systems at the mill are
included in the current estimate with appropriate hours budgeted for each system. If

not, please add this work to the estimate.
3. Insurance. Last year we requested several insurance items be included in the estimate.
The Contractor Equipment Floater, Workman's Compensation, and Employer's
Liability estimates are acceptable as included in the current estimate.
An exception is the estimate for contractor's General Liability submitted in the March
3, 2010 surety update, which we feel needs adjustment. We also desire to have
insurance for motor vehicles that will be involved in the work, included in the estimate.
For these two insurance types, we are requesting that DUSA (and the other Utah U-
mills) apply the limits of liability used by the Utah Dept. of Transportation (UDOT),
and other adjustments described in paragraphs a and b below:
a. General Liability Insurance. Last year we estimated this amount to be between
0.25 and 0.64% of the total project cost. An average amount of 0.45% was added
to the estimate. We have discovered this cost range was actually an estimate for
Builder's Risk insurance. We are not currently interested in Builder's Risk
insurance for the project. However, we are interested in budgeting for the general
liability insurance we originally intended. The extent of liability and requirements for
this insurance must have the following minimum limits of liability':
(1) . $1,000,000 Bodily Injury and Property Damage - Each Accident
(2) . $2,000,000 General Aggregate
(3) . $2,000,000 Products and Complete Operations Annual Aggregate
b. Automobile Liability Insurance. Provide Automobile Liability Insurance for
claims arising from the ownership, maintenance, or use of motor vehicles involved
in project work with the following minimum limits':
(1). $1,000,000 Combined single Limit Bodily Injury and Property Damage per
Occurrence
The costs for these insurance must be documented, based on quotes or reputable cost book
figures.
4. Reclamation costs for decommissioning, demolishing and disposal of the New Reagent
Storage Building needs to in the estimate.
5. Costs of pumping, monitoring and disposal after mill closure:
a. Slimes drain pumpage for Cells 2, 3, and 4A will be 6.5 years or more.
(1) . This adds extra time for pumping facilities and monitoring beyond the 5-
. years for environmental monitoring already budgeted, which needs to be
added to the estimate.
(2) . It seems that if reclamation were to begin now, that the tailings ponds
would be closed to acceptance of tailings and wastewater. If the White
Insurance Requirements of the UDOT Standards for Road and Bridge Construction, 2008 edition.

Ms. Jo Ann Tischler

Mesa Mill Tailings Cells are closed to further influent, the costs for a
separate pond for storage of pumpage, or other wastewater treatment
method will need to be included in the estimate,
b. Costs for treatment of the chloroform and nitrogen plumes at the White Mesa
Mill site need to be included in the estimate. Facilities and time for aquifer
pumping and related wastewater treatment or disposal pond system must be
estimated and justified. A separate wastewater treatment or disposal pond
system from the slimes drainage may be needed. It may not be feasible to co-
mingle wastewater from the chlorofonn and nitrogen plumes with slimes drain
wastewater pumpage discussed above.
6. Potential Closure of monitoring well WW2. DUSA is required to submit a plugging
and closure plan in Part I.H.3 of the imminent Ground Water Discharge Permit to
address the possibility of hydraulic interconnection of the chloroform plume and the
deep aquifer (tribal drinking water supply). Please include the costs for this plan and
implementation in the estimate.
As a reminder, surety costs must still be provided for the upcoming Cell 4B facilities, and be
approved before any operation of the cell.
Please review the above comments, and submit the requested information. In your email to us
received on June 16, 2010, you committed that DUSA would submit the subject information
within 60-days of receipt. If you have any questions on the above, please contact me.
Sincerely,

Surety Review in 2009 and 2010
May 21, 2009 DRC letter to DUSA
This MEMO is written to supplement the May 21, 2009 DRC letter to DUSA (F:\ . . . \Surety\2009\Cmtl
05-21-09.doc) on the 2009 surety estimate. However, this memo also will have application to the 2010
estimate. The content of the letter itself is self explanatory.
However, some additional study was done regarding power equipment time management and costing,
especially regarding the maintenance and repair costs for the equipment. Maintenance and repair costs are
a significant item in the project costs. This aspect is not easily broken down. A good review would
involve a parallel time bar and critical path analysis to determine if both the amount of equipment and the
maintenance are adequate.
A thorough review on this was not done due to time constraints. Evidence, that these items are inadequate,
has not been discovered. Evidence is needed to justify a request to DUSA to demonstrate the adequacy of
the equipment fleet and related maintenance. The passage of real time is an important aspect of such a
review. As mentioned, a parallel time bar and critical path analysis would be needed, to determine if both
the amount of equipment and the maintenance time is adequate.
Budgeting in the surety, to do project scheduling could be requested, and probably should be. However, at
that point, if a shortfall is discovered, it would be too late to budget in more equipment and maintenance
costs.
Additional thoughts on the power equipment and maintenance budget are preserved below:
At the bottom of page one of the February 2, 2009 letter from North Central Rental and Leasing (NCRL),
two separate maintenance rates for the power equipment are discussed. One is an hourly maintenance rate
for some materials which covers, "material part items only such as air, oil, and fuel filters," etc. This
hourly maintenance rate is included in the equipment rental cost and would be billed monthly by NCRL for
the hours on the machines. Separately, a monthly maintenance service rate is discussed below.
This monthly rate appears to be a constant stand alone monthly fee, which includes, "labor, specialized
lube trucks, support vehicles and equipment, specialized tooling,. . . parts trailers and inventories," etc.

do the reclamation. That said, is It mora/protectlve of the public to have a surety assume that we are going to use a private
gravel source, and pay a fair market price? Is it fair to assume that DRC will always be able to get a free use permit in the
future? Jj/l /MufJ-/Jj2jJ d^a^^^ , ^ /T-tA^ r/- ^^^^^ife^^-AjC^
6. We can assign an agent or contractor to remove gravel under our free use permit (3604.24).
Discussion: good, the State's 3rd party contractor can do the mining under a DRC held free use permit.
7. BLM may require a free uise piBr^nit holder to post a reclamation bond to ensure the gravel pit is reclaimed.
(3604.25)
Discussion: again, I don't see how even under a free use permit, we would avoid any / all costs for gravel.
Let me know what you think. If we need further clarification or other questions answered, please start be calling Terry Snyder
at the State BLM office at 801-539-4026.
In our surety reviews we need to examine the issue of gravel costs. For EnergySolutions, I want to tackle that in the next
surety report, due in 12/09. For the U-mills, it has already come up this year with DUSA.
Let's not drop the ball on this issue.

Re: Updated Surety Estimate, White Mesa Mill
Dear Mr. Lundberg:
Due to a change in the conventional ore processing schedule at the White Mesa Mill, Denison Mines (USA)
Corp. ("Denison") is submitting a revised surety estinnate, Revision 4.7, to reflect the additional cost for
disposal in the tailings area of a larger quantity of conventional ore than contemplated by the surety estimate
dated November 1, 2011 of $19,328,258 (the "November 1 Surety Amount"), which was approved by the
Division of Radiation Control on November 15, 2011. The disposal cost for conventional ore is estimated
through March of 2012, when the next annual surety update is due. We have also updated the quantities of
alternate feed material stored on site to reflect recent processing and projected deliveries to March 2012.
Attached for your review is Revision 4.7 of the Mill Decommissioning section of the surety estimate and a
revised Summary page detailing the new total cost of $19,420,335 (the "Updated Surety Amount"). This
revision adds approximately $92,000 to the currently approved surety amount.
Under License Condition 9.5, Denison is required to submit written evidence of the November 1 Surety
Amount within 30 days of receipt of your November 15, 2011 letter. However, in light of the foregoing, please
advise Denison if you would prefer that we:
1. submit the revised surety documents for the November 1 Surety Amount within 30 days of our receipt
of your November 15, 2011 approval, without reference to the Updated Surety Amount. The surety
would then be replaced with the Updated Surety Amount, within 30 days after approval of the
Updated Surety Amount; or
2. not submit the revised surety documents for the November 1 Surety Amount, but, instead, wait until
the Updated Surety Amount is approved, in which case a revised surety that reflects the Updated
Surety Amount would be submitted within 30 days after approval of the Updated Surety Amount.
If you advise us to follow option 2 above, we will consider that to be your waiver of the requirement to submit
the revised surety documents for the November 1 Surety Amount within 30 days of receipt of your November
15 letter.

Re: Updated Surety Estimate and Response to Utah Division of Radiation Control ("DRC") September
14, 2011 Request for Information ("RFI")
Dear Mr. Lundberg:
This letter transmits Denison Mines (USA) Corp's ("Denison's") Updated Surety Estimate and response to
DRC's September 14, 2011 Request for Information ("RFI"). This transmittal includes two hard copies of
Surety Estimate Revision 4.6. A pdf version has been transmitted via email.
For ease of review, the comments from DRC's September 14, 2011 RFI are provided verbatim below in
/fa//cs. Denson's responses follow each comment
1. General Comment: Haul routes and times are sometimes referred to in various sections of the estimate.
Please provide a detailed table and maps, which describe the haul routes, the haul route numbers,
distances, materials, and the total round trip haul times, which include the loading and unloading times, for
the various routes and materials to be transported. Adjust any affected costs resulting from the new table
values.
Denison Response: The requested information has been provided in the enclosed map of Haul Routes A
through F, and the Haul Route Summary Table and its supporting tables. Affected costs have been adjusted
accordingly.
2. Mill Decommissioning Section. The "Conventional Ore Disposal" table in this section estimates the
stockpiled weight of the ore on site at 100 lbs. /cubic foot. This seems to be a low weight for the
conventional ore we have observed stockpiled on site. Please document the current average stockpiled
weight of the conventional ore on site, and apply this value in the "Conventional Ore Disposal" portion of the
estimate.
Denison Response: Denison feels the 100 lbs/cubic foot is a conservative value and has left it unchanged.
3. Cell 1 Section.
In the table of the title "Place Lower Random Fill" in this section, scraper, compactor, D8 dozer, and D7
dozer operator tabor costs have been omitted in the portion of the table provided. Please provide
completed missing information for review.

costs for most of the power equipment operators. Please include the missing information in the
table.
Denison Response: The labor costs for power equipment operators have been added as requested,
b. A table of the title, "Rock Armor and Rip Rap Filter in this section, did not provide the extended
labor operation costs for the D7 dozer, waterwagon and motorgrader operators. Please include
these missing labor costs in this table.
Denison Response: The labor costs for the D7 dozer, waterwagon, and motorgrader operators have been
added as requested.
5. Cell 3 Section.
a. The table of the title "Clay Layer" in this section does not have the operator labor costs shown for
most of the power equipment operators. Please include the missing information in the table.
Denison Response: The labor costs for power equipment operators have been added as requested.
b. The table of the title "Upper Random Fill" in this section, as submitted, did not provide operator
labor costs for most of the power equipment operators. Please include the missing information in
the table.
Denison Response: The labor costs for power equipment operators have been added as requested.
c. A table of the title, "Rock Armor and Rip Rap Filter in this section, did not provide the extended
labor costs for the dozer, waterwagon and motorgrader operators. Please include these missing
labor costs in this table.
Denison Response: The labor costs for the D7 dozer, waterwagon, and motorgrader operators have been
added as requested.
6. Miscellaneous Section.
a. In the Slimes Drain Evaporation Pond table, a 960,000 square foot pond is contemplated.
However, there is no budget for equipment or labor to install the liner, perse: I.e. labor and
equipment to roll out, cut, seam, trim, patch, weld and test the liner Please include this cost in the
estimate.
Denison Response: The costs for installation of the liner have been added as requested.
b. Equipment Mobilization Table and the "Equipment Costs" Spread Sheet:
DENISOl
Letter to Mr. Rusty Lundberg
Revised Surety Estimate and Response to RFI
November 1, 2011
Page 3
(i) . The "Equipment Costs" spread sheet, under the primary Mob/Demob column, do not list the
corresponding current freight charges, as shown in "Attachment A" of the Feb. 16, 2011
letter from NCRL Leasing. This appears to total $$348,850.
Denison Response: The freight charges have been amended as requested.
(ii) . The "Equipment Costs" spread sheet. The "Mobilization" cost for maintenance support
personnel is $35,600 each way for a total of $71,200, per the Feb. 16, 2011 letter from
NCRL Leasing. This cost, and the amount from the above item, total $420,050. This sum
should appear on the first line of the Equipment Mobilization Table, in the miscellaneous
section of the estimate.
Denison Response: The sum has been added to the Equipment Mobilization Table as requested.
c. In the Management Support table, there are two line items, one for a part-time Environmental
Technician and one for Environmental Monitoring Lab Costs. In addition to these budgeted
amounts for environmental monitoring, the total should include any separate unique monitoring
costs required by the Annual Technical Evaluation Report (ATER), the tailings cell dewatering
elevations, surface water elevations and freeboard monitoring as required by the DMT and BAT
O&M plans, and other unique monitoring outlined section 2.3 of approved Reclamation Plan 3.2. A
single part-time technician will be unable to perform all of these tasks without assistance. Please
breakdown these costs to demonstrate that alt these monitoring costs (including all necessary
technician labor hours) are covered in the surety estimate.
Denison Response: The cost breakdown has been added as requested.
Please contact me if you have any questions or require any further information.
Yours very truly,

1) Removal of contaminated material from Mill Yard
Assume:
- 18 inches (1.5 feet) will have to be removed
- Area (from CAD takeoff) = 1,643,453 sq. feet
37.7 acres
Therefore: Volume moved = [ 1,643,453 x 1.5]/27 = 91,303 cubic yards
(use 91,300)
91,300 / 355 cubic yards per hour = 257 machine hours

- Bridging layer is placed using random fill from piles east and west of Cell 3
- Cell will be graded to Design elevation utilizing finer materials in random fill stockpiles
and from "clay" stockpiles.
- Clay will be mined, blended, and hauled from borrow site location in Section 16 -
four miles south of the mill area, using belly dump trucks, clay layer on top of Cell only.
- The upper 1 foot of random fill will be placed utilizing the fine random fill and clay stockpiles
- Rock for side armor, top armor and toe aprons will come from an off-site gravel source
one (1) mile north of Blanding. Rock will be produced through screening, stockpiled and
trucked to the site at the time of use. Belly dump trucks will dump gravel in windrows
on the top and sides of the Cell.

Volume Calculation - Cell 4A
1) Area of Cell 4A - 1,785,960 sqft = 41.00 acres
Updated 02/24/11
//-O/-//
2) Assumptions
- Bridging layer is placed using random fill from piles east of Cell 4A
- Cell will be graded to Design elevation utilizing finer materials in random fill stockpiles
and from "clay" stockpiles.
- Clay will be mined, blended, and hauled from borrow site location in Section 16 -
four miles south of the mill area, using belly dump trucks, clay layer on top of Cell only.
- The upper 1 foot of random fill will be placed utilizing the fine random fill and clay stockpiles
- Rock for side armor, top armor and toe aprons will come from an off-site gravel source
one (1) mile north of Blanding. Rock will be produced through screening, stockpiled and
trucked to the site at the time of use. Belly dump trucks will dump gravel in windrows
on the top and sides of the Cell.
3) Bridging Layer ( Platform Fill) Remaining to be placed
1,785,960 sqft X 3 ft. / 27 cubic feet per cubic yard = 198,440 cubic yards
Use I 198.500 cubic yardT
4) Bring Platform Fill up to Design elevation (Lower Random)
Assume full area of Cell X one (1) foot thick
1,785,960 sqft X 1ft. / 27 cubic feet per cubic yard = 66,147 cubic yards
Use I 66,000 cubic yards |
5) Placement of Clay Layer ( One (1) foot thick on top of Cell only )

2) Assumptions
- Bridging layer is placed using random fill from piles west of Cell 4B
- Cell will be graded to Design elevation utilizing finer materials in random fill stockpiles
and from "clay" stockpiles.
- Clay will be mined, blended, and hauled from borrow site location in Section 16 -
four miles south of the mill area, using belly dump trucks, clay layer on top of Cell only.
- The upper 1 foot of random fill will be placed utilizing the tine random till and clay stockpiles
- Rock for side armor, top armor and toe aprons will come from an off-site gravel source
one (1) mile north of Blanding. Rock will be produced through screening, stockpiled and
trucked to the site at the time of use. Belly dump trucks will dump gravel in windrows
on the top and sides of the Cell.
