Notice of Intent To Prepare an Environmental Impact Statement for 
the Proposed Castle Mountain Mine Phase II Expansion, San Bernardino 
County, California and Clark County, Nevada

AGENCY: Bureau of Land Management, Interior.

ACTION: Notice of intent.

-----------------------------------------------------------------------

SUMMARY: In compliance with the National Environmental Policy Act of 
1969, as amended (NEPA), the Federal Land Policy and Management Act of 
1976, as amended, (FLPMA), and Section 106 of the National Historic 
Preservation Act of 1966, as amended (NHPA) the Bureau of Land 
Management (BLM) Needles Field Office (NFO), Needles, California 
intends to prepare an Environmental Impact Statement (EIS) to consider 
the effects of the proposed Castle Mountain Mine Phase II Expansion 
Project in San Bernardino County, California and Clark County, Nevada. 
This notice announces the beginning of the scoping period to solicit 
public comments and identify issues under NEPA and Section 106 of the 
NHPA.

DATES: This notice initiates the public scoping process for the EIS. 
The BLM requests that the public submit your comments concerning the 
scope of the analysis, potential alternatives, and identification of 
relevant information, and studies by November 19, 2025. To afford the 
BLM the opportunity to consider comments, please ensure your comments 
are received prior to the close of the 30-day scoping period.

ADDRESSES: You may submit comments related to the Castle Mountain Mine 
Phase II Expansion Project by any of the following methods:
     Website: https://eplanning.blm.gov/eplanning-ui/project/2039209/510.
     Mail: Project Manager, BLM Needles Field Office, 1303 U.S. 
95, Needles, CA 92363.
    Documents pertinent to this proposal may be examined online at 
https://eplanning.blm.gov/eplanning-ui/project/2039209/510 and at the 
BLM Needles Field Office during regular business hours.

FOR FURTHER INFORMATION CONTACT: Castle Mountain Project Manager, 
telephone 760-326-7000; address: Bureau of Land Management Needles 
Field Office, 1303 U.S. 95, Needles, CA 92363. Individuals in the 
United States who are deaf, deafblind, hard of hearing, or have a 
speech disability may dial 711 (TTY, TDD, or TeleBraille) to access 
telecommunications relay services. Individuals outside the United 
States should use the relay services offered within their country to 
make international calls to the point-of-contact in the United States.

SUPPLEMENTARY INFORMATION: The BLM will consider authorizing an 
amendment to Castle Mountain Venture's (CMV) mine plan of operations to 
address the proposed expansion of surface disturbance (Phase II 
Expansion) on public lands (Proposed Action) at the Castle Mountain 
Mine (CMM). The Project is located approximately 60 miles south of Las 
Vegas, Nevada, and 40 miles northwest of the BLM office in Needles, 
California. The proposed expansion of the mine pits, overburden sites, 
and heap leach pad and installation of the associated pipeline and 
powerline would disturb an additional 1,800 acres of BLM-managed public 
land for a total project disturbance of 3,294 acres.

Purpose and Need for the Proposed Action

    The BLM's purpose is to respond to CMV's request to amend the mine 
plan of operations and authorize the Utilities Plan of Development for 
CMM and to analyze the environmental effects associated with the 
proponent's Proposed Action and alternatives to the Proposed Action, 
consider reasonable alternatives, and develop and consider mitigation 
when necessary to mitigate environmental effects.
    The need for the action is established by the BLM's responsibility 
under the Mining Law of 1872, Section 302 of FLPMA and the BLM 
regulations at 43 CFR part 3809 and 43 CFR part 2800. These statutes 
and regulations set forth the BLM's responsibility to ensure that 
operations under the Mining Law of 1872 prevent unnecessary or undue 
degradation of public lands.

Preliminary Proposed Action and Alternatives

    The Proposed Action would consist of an expansion of CMV's 
authorized plan of operations for the CMM under the regulations found 
at 43 CFR part 3800, subpart 3809. The Proposed Action would also 
include the authorization of rights-of-way for an underground water 
pipeline and overhead powerline under the regulations found at 43 CFR 
part 2800.
    The expansion would extend the mine life of CMM by approximately 30 
years and operations would effectively quadruple the annual mining rate 
at the mine. An underground water pipeline and overhead powerline are 
needed to meet the increased groundwater and power demands of the 
proposed expansion. The proposed expansion of the mine pits, overburden 
sites, heap leach pad and installation of the associated pipeline, 
powerline, and onsite power generation would disturb an additional 
1,800 acres of BLM-managed public land.
    Under the National Park Service Lands Alternative, the Proposed 
Action would remain the same as with the exception that the utilities 
corridor would follow the road route across a ~1,000-foot section of 
land within the Mojave National Preserve that is currently managed by 
the National Park Service.
    Under the no action alternative, the BLM would not approve the 
proposed amendment to the plan of operations, and the activities 
described in the Proposed Action would not occur. The proposed 
expansion areas, underground water pipeline, and overhead powerline 
would not be constructed and operations under the currently authorized 
mine plan would continue.
    The BLM welcomes comments on all preliminary alternatives as well 
as suggestions for additional alternatives.

Summary of Expected Impacts

    The Project's proximity to Castle Mountains National Monument and 
Mojave National Preserve has raised concerns that increased visual and 
noise disturbances from mining construction and operations might affect 
recreational and traditional use, cultural sites, seeps and springs, 
and biological resources in the area. While there are concerns over 
habitat loss and impacts to native vegetation, the mine continues to 
provide guzzlers for wildlife and has a rare native plant nursery. The 
mine is recognized for its successful reclamation methods and hosts on-
site research dedicated exclusively to cultivating vegetation native to 
the Mojave Desert.

Anticipated Permits and Authorizations

    In addition to the requested authorization to perform mineral 
extraction under a mining plan of operations, other Federal, state, and 
local authorizations would be required for the project. These include 
authorizations under the Endangered Species Act, the Clean Water Act, 
and other laws and regulations determined to be applicable to the 
project.

Schedule for the Decision-Making Process

    The BLM will provide opportunity for public participation 
consistent with the NEPA process. The Draft EIS is anticipated to be 
available for public review spring 2026 and the Final EIS is 
anticipated to be released in summer 2026 with a Record of Decision 
fall 2026.

Public Scoping Process

    This notice of intent initiates the scoping period. The BLM will 
hold one in-person public scoping meeting. The specific date and time 
of this scoping meeting will be announced at least 15 days in advance 
on the BLM website https://www.blm.gov/california and at https://eplanning.blm.gov/eplanning-ui/project/2039209/510.

Responsible Official

    Ron Nuckles, Field Manager, Needles Field Office, California Desert 
District, Bureau of Land Management.

Nature of Decision To Be Made

    The BLM's potential decision relative to the proposed amendment as 
informed by the EIS includes: (1) approval of the proposed Castle 
Mountain Mine Amendment to Plan of Operations Project as submitted; (2) 
approval of the proposed Castle Mountain Mine Amendment to Plan of 
Operations Project subject to changes or conditions, as analyzed in the 
EIS, that the BLM deems necessary to prevent unnecessary or undue 
degradation of public lands; or (3) denial of the proposed Castle 
Mountain Mine Amendment to Plan of Operations Project if the BLM 
determines that the proposal would result in unnecessary or undue 
degradation of public lands.

Additional Information

    The BLM will utilize and coordinate the NEPA process to help 
support compliance with applicable procedural requirements under the 
Endangered Species Act (16 U.S.C. 1536) and Section 106 of the National 
Historic Preservation Act (54 U.S.C. 306108) as provided in 36 CFR 
800.2(d)(3), including public involvement requirements of Section 106. 
The information about historic and cultural resources and threatened 
and endangered species within the area potentially affected by the 
proposed project will assist the BLM in identifying and evaluating 
impacts to such resources.
    The BLM will consult with Indian Tribal Nations on a government-to-
government basis in accordance with Executive Order 13175, BLM Manual 
Section 1780, and other Departmental policies. Tribal concerns, 
including impacts on Indian trust assets and potential impacts to 
cultural resources, will be given due consideration. Federal, state, 
and local agencies, along with Indian Tribal Nations and other 
stakeholders that may be interested in or affected by the proposed 
action that the BLM is evaluating, are invited to participate in the 
scoping process and, if eligible, may request or be requested by the 
BLM to participate in the development of the environmental analysis as 
a cooperating agency.
    Before including your address, phone number, email address, or 
other personal identifying information in your comment, you should be 
aware that your entire comment--including your personal identifying 
information--may be made publicly available at any time. While you can 
ask us in your comment to withhold your personal identifying 
information from public review, we cannot guarantee that we will be 
able to do so.
