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 estimate, 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 aisp 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.
Letter to Mr. Rusty Lundberg
