Re: October 15, 2010 DUSA Response Letter to September 23, 2010 DRC Request for Information; March
3, 2010 DUSA Letter, 2010 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 iri 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 $2187per 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/month for corresponding
fuel 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 ofthe 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 I 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 buildingjust north of the are 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.
Please contact the undersigned if you have any questions or require any further information.
Yours very truly,
DENISON MINES (USA) CORP.
