Re: White Mesa Mill Abandonment Plan for Selected TWN-Series Wells
This letter transmits Energy Fuels Resources (USA) Inc.'s ("EFRI's") Well Abandonment Report for
Selected TWN-Series Wells at White Mesa Mill (the "Report"), prepared by our hydrogeological
consultant, Hydro Geo Chem. Inc. This Report was prepared consistent with the requirements of the
approved May 7, 2013 Nitrate Corrective Action Plan ("CAP") Section 7.2.1 and the DRC-approved
Well Abandonment Plan dated May 20,2013.
Section 7.2.1 of the CAP requires that the wells addressed by the Abandonment Plan be abandoned
within one year of the December 12, 2012 approval of the CAP, and an abandonment report be
submitted to the Director within 15 months after the December 12, 2012 approval date of the CAP. The
attached Report is submitted to meet the reporting requirements specified in the approved CAP.
Please contact me at [phone] if you have any questions or require any further information.
Yours very truly,

Re: TWN-series Well Abandonment: White Mesa Uranium Mill Near Blanding, Utah
Dear Ms. Weinel
This letter describes the abandonment of temporary perched nitrate monitoring wells TWN-5, TWN-
8, TWN-9, TWN-10, TWN-11, TWN-12, TWN-13, TWN-15, and TWN-17, pursuant to Section
7.2.1 of the May 7, 2012 Correction Action Plan for Nitrate, White Mesa Uranium Mill Near
Blanding, Utah (the CAP). The abandonment was performed by Bayles Exploration, Inc, a State of
Utah licensed driller under contract to Energy Fuels Resources (USA) Inc, in accordance with
applicable regulations (State of Utah Administrative Rules for Water Wells R655-4-14).
Background
At the time of abandonment, the White Mesa site contained a total of 101 perched monitoring wells,
temporary perched monitoring wells, and piezometers (Figure 1), all screened in a relatively shallow
perched water zone hosted primarily by the Burro Canyon Formation. Where saturated thicknesses
are greater, the perched water rises into the overlying Dakota Sandstone. The perched water is
supported by the Brushy Basin Member of the Morrison Formation, a bentonitic shale (considered
impermeable) that underlies the Burro Canyon Formation.
The 19 existing and abandoned TWN-series temporary wells, located north-northeast (upgradient) of
the tailings cells at the site, were installed primarily to monitor hydraulic conditions and nitrate
concentrations in the northeast portion of the site. Many of these wells help to define a perched zone
nitrate plume that extends from a location northeast (upgradient) of the tailings cells to the northeast
portion of the tailings cell complex.

Based on criteria provided in the CAP, some of the TWN-series wells were retained for water level
and groundwater quality monitoring, and some for water level monitoring only. Wells TWN-5,
TWN-8, TWN-9, TWN-10, TWN-11, TWN-12, TWN-13, TWN-15, and TWN-17 (Figure 1) were
not needed for either purpose and were targeted for abandonment.
Well Construction
Table I provides well construction details for all abandoned TWN-series wells and Table 2 provides
surveyed well locations and elevations. Appendix A contains the well construction diagrams. Depths
of abandoned wells ranged from approximately 102.5 to 155 feet below land surface (bis) and each
boring extended a few feet into the underlying Brushy Basin Member of the Morrison Formation. As
noted above, the Brushy Basin is bentonitic and considered impermeable. The variability in well
depth was primarily due to the irregular elevation of the Burro Canyon/Brushy Basin contact in this
portion of the site.
Each abandoned well was constructed within a nominal 6 3A - inch diameter borehole using 4-inch
diameter flush-thread schedule 40 PVC casing and 0.02-slot factory slotted PVC screen. The annular
space within each screened interval contained a Colorado silica sand filter pack overlain by a
bentonite seal of approximately 3 to 5 foot thickness. The screened intervals ofthe abandoned wells
ranged in length from 50 to 80 feet, and the filter pack lengths from approximately 55.5 to 87.5 feet.
The variability in screened length was related to the variable saturated thickness ofthe perched zone
in this portion of the site.
The annular spaces above the seals in each well were grouted to the surface. Because the well casings
were grouted in place, pulling of casings prior to abandonment was considered infeasible.
Well Abandonment
Wells were abandoned on July 31,2013 by Bayles Exploration Inc, a currently licensed water well
driller responsible for verification of the procedures and materials used. Details ofthe abandonment
procedures are provided in the well abandonment report prepared and submitted by Bayles
Exploration Inc. The Bayles report is attached as Appendix B.
Please feel free to contact me if you have any questions.
