Jane Dough ISL project

> View deposit info

Uranerz submits license application for Jane Dough uranium in situ leach project as extension of Nichols Ranch mine: On May 21, 2014, Uranerz Energy Corporation announced that it has submitted the source material license amendment application for its Jane Dough unit to the U.S. Nuclear Regulatory Commission. The Jane Dough permit area, located in the Central Powder River Basin of Wyoming, U.S.A., is contiguous to and immediately south of the Company's wholly owned Nichols Ranch unit which recently commenced in-situ recovery ("ISR") uranium mining operations.
Uranerz is applying to add the Jane Dough unit as an amendment to the existing license for the Nichols Ranch ISR Uranium Project, which includes the Nichols Ranch and Hank units. Due to the close proximity of these two units, the Company expects to install only the wellfields at Jane Dough and will transfer mining solutions to and from the processing plant at the Nichols Ranch unit through pipelines.

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.

> View BLM Rawlins field office project site external link

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. (Energy Fuels Mar. 28, 2014)

Juniper Ridge acquired by Energy Fuels Inc.: Through its purchase of Strathmore on August 30, 2013, Energy Fuels Resources now controls 100% of the project.

Crosshair terminates acquisition of Juniper Ridge property: On Nov. 30, 2012, Crosshair Energy Corp announced that it has terminated the Purchase and Sale Agreement dated October 29, 2010, between the Company and Strathmore Resources (US) Ltd. and Strathmore Minerals Corp. with respect to the sale, by Strathmore, of 100% of the Juniper Ridge property.

BLM seeking comment on the Juniper Ridge uranium exploration project: The Bureau of Land Management (BLM) Rawlins Field Office is launching a 30-day public comment period on a Plan of Operations (POO) for the Juniper Ridge Uranium Exploration Project, located roughly seven miles west of Baggs, Wyo., in Carbon County.
The Juniper Ridge project is proposed by 448018 Exploration, Inc., based in Vancouver, British Columbia. The project area would encompass some 8,320 acres of public land. The proposal includes developing up to 487 mud rotary drill sites, trenching or bulk sampling, construction of new roads and an equipment and vehicle storage area. In addition, up to 10 drill holes will be converted to ground water monitoring wells. Surface disturbance is expected to be up to 54 acres.
Comments should be received by June 8, 2012.

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 external link) 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 Jan. 17, 2008, NRC issued an Opportunity to Request a Hearing on Energy Metals Corp.'s license application for the Moore Ranch in-situ leach uranium project.
