Bureau of Land Management invites comment on proposal to develop the Pathfinder Mines Corp. Shirley Basin uranium mine:
The proposed project submitted by Pathfinder Mines Corporation would be 40 miles south of Casper on a former uranium mine that operated from the 1960s through the 1990s. Input received during the preliminary scoping period will help the BLM determine the best approach to analyze the proposal.
The Shirley Basin project would use the same in-situ recovery methods that the BLM analyzed in the Lost Creek final environmental impact statement, released Dec. 28, 2018. Because the projects are similar, the BLM will likely refer to the resource information and impact analyses developed for Lost Creek, as appropriate, to inform the Shirley Creek analysis, the release states.
For more details, call Project Coordinator Annette Treat at 307-328-4314 or go to DOI-BLM-WY-D030-2015-0221-EIS (Lost Creek Uranium Mine modification-expansion) . The BLM will post information specific to Shirley Basin once the formal analysis begins.
Residents can contribute input through March 25, 2019. Comments can be submitted by mail to the Rawlins Field Office, PO Box 2407, Rawlins WY 82301, or by email to blm_wy_rawlins_WYMail@blm.gov.

Uranerz defers license application for Jane Dough uranium in situ leach project, once again: On Dec. 9, 2013, Uranerz Energy Corp. notified the Nuclear Regulatory Commission (NRC) of a revision of the estimated submittal date for the Jane Dough Unit amendment application to the first quarter of 2014.
Uranerz defers license application for Jane Dough uranium in situ leach project, again: On Apr. 15, 2013, Uranerz Energy Corp. notified the Nuclear Regulatory Commission (NRC) of a revision of the estimated submittal date for the Jane Dough Unit amendment application to the fourth quarter of 2013.
Uranerz defers license application for Jane Dough uranium in situ leach project: On Nov. 5, 2012, Uranerz Energy Corp. notified the Nuclear Regulatory Commission (NRC) of a revision of the submittal date for the Jane Dough Unit amendment application to the second quarter of 2013.
Uranerz to seek license for Jane Dough ISL project as extension of Nichols Ranch: On Oct. 7, 2011, Uranerz Energy Corp. notified the Nuclear Regulatory Commission (NRC) of its intent to submit an amendment to the Nichols Ranch ISR Project Source Material License SUA-1597 for the Jane Dough Unit in the fourth quarter of 2012. The permit boundary for the Jane Dough Unit is directly south and contiguous with the Nichols Ranch Unit.
Permit applications initiated for Jane Dough uranium in situ leach project:
On March 24, 2010, Uranerz Energy Corporation announced that it has commenced preparation of environmental permit and license applications for its planned third ISR uranium mining unit in the central Powder River Basin of Wyoming. This unit, newly named Jane Dough, includes the Doughstick, South Doughstick and North Jane uranium properties.
The Jane Dough permit area will be adjacent to and immediately south of the Nichols Ranch permit area, and the Company intends to add the Jane Dough Unit as an amendment to the Nichols Ranch ISR Project license, once that license has been received. Due to the proximity of these two units, it is likely that instead of building a satellite plant at Jane Dough, it will be possible to install pipelines to transfer the mining solutions to/from Jane Dough to the planned central processing plant at the Nichols Ranch Unit. This initiative could result in considerable capital cost savings for Jane Dough.
Energy Fuels plans open pit mine with heap leaching at Juniper Ridge:
Under the base-case scenario in the preliminary economic assessment ("PEA"), the Company anticipates utilizing open pit mining in conjunction with on-site heap leach recovery that produces an intermediate uranium concentrate in the form of loaded resin, which could be shipped to Energy Fuels' 100% owned White Mesa Mill near Blanding, Utah (or other regional facilities) for final processing.
Under the base-case scenario in the PEA, the Juniper Ridge Project is expected to produce a little over 500,000 pounds of U3O8 (192 t U) per year over a 10-year mine life.
The PEA assumes a constant uranium price of $65/pound over the 10-year life of the project.

Mar. 5, 2010: Interior Department says sage grouse deserves -- but won't get -- protection
On Oct. 28, 2009, Uranium One requested that "the NRC defer all further review of the Antelope and JAB application until such time that Uranium One requests resumption. The reason for this request is the uncertainty involved with the potential listing of the Greater Sage Grouse under the Endangered Species Act. The Antelope and JAB project lies within an area identified by the State of Wyoming as a "core" area for management of the sage grouse. Should the bird be listed, future development of energy projects including uranium, oil and gas, and wind in these areas could be seriously jeopardized. A decision on whether a listing for the sage grouse is warranted is expected by February 26, 2010."
On Aug. 6, 2009, NRC issued a Notice of Intent to Prepare a Supplemental Environmental Impact Statement for the Antelope and JAB Uranium Project.

On May 14, 2008, NRC sent Energy Metals Corp a request for additional information (ADAMS Acc. No. ML081340113 ) regarding its license application for the Moore Ranch in-situ leach uranium project:
We identified significant concerns related to both groundwater and radiological protection. Our most significant groundwater concerns relate to the absence of underlying shale in a portion of the production zone, the effects of coal bed methane produced water on surface and groundwater, the unconfined conditions in the production zone, and the estimate of the number of pore volumes that will be required to restore the production zone. Our most significant radiological protection concerns relate to the design objective of the ventilation system and the adequacy of radiological environmental monitoring. [...]The unconfined aquifer in the proposed "70 sand" production zone is a unique setting for an ISL operation [emphasis added]. The unconfined aquifer setting presents an entirely different hydrogeologic flow regime which has implications for well field balancing, communication with monitoring wells and overlying and underlying aquifes, excursion monitoring/correction, lixiviant behavior and restoration. [...]
The confinement of the "70 sand" is in question based on the acknowledged absence of the underlying shale between the "70 sand" and "68 sand" in a large portion of Wellfield 2, the potential absence of the underlying shale in Wellfield 1, and the absence of overlying shale on the isopach just northwest of Wellfield 3. [...]

On July 6, 2006, NRC held a pre-licensing meeting with Uranerz Energy Corporation to discuss potential uranium recovery applications for its Nichols Ranch uranium in-situ leach project.
Uranerz Energy Corporation ("Uranerz") is planning to construct and operate a uranium in situ recovery (ISR) facility with the name Nichols Ranch ISR Project that incorporates two production units; the Nichols Ranch ISR Main Unit
consisting of a complete processing facility and in situ recovery mine, and the
Hank ISR Satellite Unit consisting of an ion exchange facility and an in situ
recovery mine. The Nichols Ranch Unit processing facility will have the capacity
to produce approximately 750,000 pounds of dry yellow cake product (288 t U) per year. It is planned that approximately half of this amount will originate from the Nichols Ranch ore body while the remaining half will be produced from the Hank ore body.
Uranerz is planning to submit the license application in the second quarter of 2007 and start operation in 2009.
