Angus! 2006 See Reverse for Instructions Subject: Energy Fuels Resources (USA) Inc. 2nd Quarter 2013 Groundwater Monitoring Report for the White Mesa Uranium Mill, Blanding, UT, Groundwater Discharge Permit No. UGW370004: DRC Conditional Approval and Close out Dear Ms. Tischler: The Utah Division of Radiation Control ("DRC") has reviewed the following Energy Fuels Resources (USA) Inc. ("EFR") documents: 1. The EFR, August 26, 2013,2nd Quarter 2013 Groundwater Monitoring Report ("Report") Groundwater Discharge Permit UGW370004 ("Permit"), White Mesa Uranium Mill; 2. The EFR, August 23,2013, Notice Pursuant to Part I.G. 1 (a) Q2, 2013, and; 3. The EFR September 20,2013 Transmittal of Plan and Time Schedule under Utah Ground Water Discharge Permit UGW370004 Part I.G.4(d) for the White Mesa Mill. The review was conducted with consideration of the following related actions: 1. An October 10, 2012 EFR Source Assessment Report, an April 13, 2012 EFR pH Report, and a December 12, 2012 EFR Pyrite Investigation Report for previously documented out-of-compliance parameters (multiple parameters) which were required per DRC Stipulated Consent Agreement, Docket No. UGW12-03. Per DRC findings, and as documented in a DRC review memo, dated April 23, 2013 and transmitted via letter to EFR dated April 25, 2013, it is recommended that; 1. Specific GWCL parameters for site monitoring wells be modified (12 instances), 2. GWCL's for pH be modified for all site monitoring wells, and 3. That GWCL's be removed from the Permit for 3 monitoring wells up gradient from the site. These requests are currently being addressed through the permit modification process. 2. A May 25, 2012 EFR Permit Modification Request - DRC notified EFR by letter (dated April 16, 2012) that in order to formalize an April 5, 2010 telephone discussion between DRC and EFR representatives, allowing a change to accelerated monitoring requirements, a written request was required for Director review and approval. Subsequently, EFR submitted a May 25, 2012 written request for the Permit modification, including redline copies of pertinent pages of the Permit to reflect the agreements made during the April 5, 2010 conference call. This request is currently 195 North 1950 West • Salt Lake City, UT Mailing Address P O Box 144850 • Salt Lake City, UT 84114-4850 Telephone (801) 536-4250 • Fax (801) 533-4097 • T D.D (801) 536-4414 »w deq Utah gov Pnnted on 100% recycled paper Jo Ann Tischler Page 2 being addressed through permit modification.

Depth to Water & Groundwater Elevation Measurement and Mapping Based on review of the Report, it appears that all requirements of the Permit have been addressed. Therefore, the review is hereby closed out. Conditional Approval for Adjusted Gross Alpha OOCPlan and Time Schedule, Monitoring Well MW-32 EFR proposes to submit a Source Assessment Report ("SAR") for Adjusted Gross Alpha at monitoring well MW-32 within 90 days of Director approval ofthe September 20, 2013 Plan and Time Schedule. Per EFR, the SAR will include a geochemical analysis of gross alpha and indicator parameters (chloride, fluoride, sulfate and uranium) in monitoring well MW-32. The intention will be to determine if "the behavior of the water in MW-32 has changed since the time of the New Wells Backgrowid Reporf (Intera, 20071). EFR notes that if the OOC status is determined to be caused by background influences, then no additional evaluation to determine the extent and potential dispersion of the contamination will be necessary. In the event that a background determination is made then EFR will submit to the Director, as part of the SAR, a proposed revised GWCL for adjusted gross alpha in monitoring well .MW-32. If a proposed revised GWCL is included, then statistical analysis, as described in the Existing Wells Background Report (Intera, 2007), and according to the Director approved flow sheet for statistical analysis of GWCL revisions will be used. EFR additionally notes that groundwater background concentration determinations at the White Mesa Mill were recently studied per 1) The White Mesa Background Groundwater Quality Report (Intera 20071), 2) The October 12, 2012 Source Assessment Report2 for several parameters in OOC status, and 3) The University of Utah Study at the White Mesa Mill (Hurst and.Solomon 20083). EFR notes that in some cases, such as at monitoring well MW-32, limited indicator parameter data was available at the time of the past background studies. INTERA Incorporated, 2007.

The SAR for Adjusted Gross Alpha at groundwater monitoring well MW-32 will include all study elements and report structure of the October 10, 2012 EFR Source Assessment Report (approved by the Director through Stipulated Consent Agreement UGW12-03), including graphs, plots and charts, and; 2. The SAR will be submitted on or before 90 calendar days from EFR receipt of this conditional approval letter. .
