Austin, Texas–(Newsfile Corp. – April 1, 2026) – American Antimony Corporation, operating as Xtra Energy Corp. (OTCID: XTPT), today announced the initiation of the Small Mine Permit process for its Antimony King Mine within the Company’s American Antimony Project in Bernice Canyon, Nevada.
The permitting process is being advanced in collaboration with Westland Resources, the same firm that successfully permitted the Company’s Phase 1 drilling campaign, providing continuity and permitting expertise as the project progresses from exploration toward early-stage mining activities.
In parallel with ongoing metallurgical and development work at Antimony King, the Company has initiated permitting activities to support the next stage of responsible project advancement. Westland Resources, which successfully permitted the Company’s Phase 1 drilling campaign, has commenced work on the Small Mine Permit application. This permit is designed to support a limited, approximately five-acre operational footprint and represents an important step in advancing near-term, small-scale production activities while maintaining a disciplined, staged approach toward building a secure, domestic antimony supply. As the permitting process progresses, American Antimony expects to provide periodic updates as regulatory milestones are achieved and the application advances through the review process.
Small Mine Permit Overview
In Nevada, a Small Mine Permit authorizes limited mining and material handling activities within a disturbance footprint of up to five (5) acres. This permitting pathway is specifically designed to allow early-stage mining operations, bulk material handling, and stockpile management to proceed under defined environmental controls, reclamation bonding, and regulatory oversight.
The Small Mine Permit represents a critical transition point between exploration-stage activities and larger-scale development, enabling companies to responsibly evaluate and advance mineral assets while maintaining a limited surface impact.

This stepwise strategy is designed to responsibly advance bulk sampling, metallurgical optimization, and incremental supply growth while maintaining regulatory compliance and minimizing surface disturbance.

Focus on Antimony King and Existing High-Grade Material
At Antimony King, the Small Mine Permit is expected to support controlled access to existing mineralized zones and historic stockpiles derived from past production. The mine hosts documented high-grade antimony mineralization, existing underground workings, and previously mined material that provides an opportunity to advance bulk sampling, metallurgy, and early-stage material management with minimal new disturbance.
The Company’s strategy is centered on stepwise development, prioritizing existing infrastructure and historic material while advancing technical understanding of grade, metallurgy, and processing pathways.
Strategic Importance
The Small Mine Permit is intended to support:
-
Bulk sampling and material handling at meaningful scale
-
Expansion and management of historic stockpiles
-
Metallurgical testing and processing optimization
-
Early-stage mine planning and logistics evaluation
-
Continued environmental stewardship and reclamation
While limited to five acres, the permit serves as a foundational building block toward a larger, scalable development pathway as project data, permitting, and market conditions evolve.
Advancing a Domestic Antimony Supply
Antimony is recognized as a critical mineral with limited domestic supply. The Company views the Antimony King Mine as a key asset within a broader strategy to responsibly develop U.S.-sourced antimony supply, utilizing established permitting pathways and disciplined, staged project advancement.
By progressing through the Small Mine Permit process, the Company continues to advance Antimony King from exploration toward early mining activities in a manner consistent with regulatory requirements, environmental responsibility, and long-term development objectives.
CEO Commentary
“Initiating the Small Mine Permit process represents a logical and disciplined next step for the Antimony King Mine,” said Mac J. Shahsavar, P.Eng., Chairman and Chief Executive Officer of American Antimony Corp. “Having successfully completed Phase 1 drilling under permit with Westland Resources, we are maintaining continuity as we progress from exploration toward early-stage operational activities. This approach allows us to responsibly advance the project while continuing to de-risk development through permitting, metallurgy, and staged execution.”
About American Antimony Corporation
American Antimony Corporation (OTCID: XTPT), operating as Xtra Energy Corp., is advancing high-grade antimony assets in the United States to support secure, domestic supply of this critical industrial mineral, which is used in flame retardants, batteries, defense alloys, and emerging energy applications.
The Company’s flagship American Antimony Project comprises approximately 201 claims totaling 4,153 acres in the prolific Bernice Canyon district of Nevada and includes the historically productive Antimony King Mine. Recent exploration and metallurgical work have returned exceptionally high antimony head grades, reinforcing the high-grade potential of the system.
In addition, the Company has expanded its Nevada footprint through the acquisition of 1,240 acres at the Stibium Creek Project in Lander County, a proven antimony corridor with established mineralization and infrastructure. American Antimony is pursuing a disciplined, staged development strategy encompassing exploration, permitting, metallurgy, and early-stage mining, with the objective of producing high-grade antimony concentrates to support domestic and global supply needs.
