#US Antimony Corporation Provides Update on Mining Operations
On August 5, 2026, United States Antimony Corporation (USAC) announced a comprehensive update regarding its mining activities across Alaska, Montana, and Canada. The company, recognized as a leading producer of antimony and critical minerals, highlighted its ongoing and future exploration projects, which are pivotal to increasing domestic mineral supply.
USAC is actively involved in several projects in Alaska, particularly the Ester Dome area, covering over 9,000 acres. This exploration stage project, located just seven miles from Fairbanks, includes four distinct claim blocks acquired in 2025. USAC plans to conduct extensive drilling, targeting areas reported to contain high concentrations of antimony, linked to historical gold mining activities.
In addition, USAC is developing several other properties in Alaska, including Stibnite Creek, Maclaren River Area Properties, True North Claims, Dome Creek Placer, and Nolan Creek. Notably, the Nolan Creek site features an inferred reserve of 42,412 tons of both antimony and gold, with mining activities slated to commence by late 2026.
#Montana Operations and Environmental Considerations
In Montana, the Stibnite Hill operation is progressing, having resumed with a recent delivery of ore to the Radersburg Mill. This project is essential for meeting contract specifications with the Defense Logistics Agency for antimony metal ingots. USAC has implemented environmental safeguards to prevent soil contamination at excavation sites, as mandated by state regulators.
USAC is also making strides in Canada with the Fostung Deposit in Ontario. The company has engaged qualified bidders for mining and drilling operations, aiming to collect a significant bulk sample for analysis and subsequent processing. This initiative underscores USAC's commitment to expanding its production capabilities across North America.
The overarching goal for USAC is to diminish reliance on foreign antimony sources. By increasing its own mining output, the company aims to enhance logistical efficiency and improve profit margins. As it transitions toward self-sourced production, USAC anticipates fulfilling the growing demand from its customers, including U.S. military contracts.
United States Antimony Corporation (USAC) has reported updates on several mining activities in Alaska, Montana, and Canada. Active projects include Ester Dome, Stibnite Creek, Maclaren River Area Properties, and Nolan Creek in Alaska. In Montana, operations at Stibnite Hill have resumed, and in Canada, activities related to the Fostung Deposit in Ontario are underway.
Ester Dome is an exploration stage project in Alaska covering over 9,000 acres with indications of high antimony content. The project aims to evaluate historical reports of stibnite, which is associated with gold mineralization. The Company plans to drill up to 50 holes in the area to explore further.
The Nolan Creek property was acquired through a Trustee's Sale, with previous exploration and mining conducted over 20 years ago. A technical report indicates inferred reserves of antimony and gold, with mining operations set to begin later this year. The Company will truck raw ore to its Radersburg Mill for processing.
USAC has implemented additional safeguard procedures at the Stibnite Hill site to control potential contamination of surrounding soils, responding to recommendations by the Montana Department of Environmental Quality. These measures have been approved, allowing mining activities to continue.
USAC primarily produces and processes antimony, zeolite, and precious metals, including gold and silver. The Company also recovers antimony oxide, which is used in various industries including flame retardants and battery production, highlighting its role in the supply chain for military-grade ingots.
USAC faces several risks, including fluctuating market prices for antimony and zeolite, operational risks from mining, regulatory challenges, and environmental factors. Weather conditions and potential changes in the economy may impact operations, and additional risks are detailed in the Company's filings with the U.S. Securities and Exchange Commission.
The Company's strategy includes reducing reliance on third-party antimony ore by increasing its own mined production and expanding its product offerings. This effort is aimed at enhancing logistical efficiency and improving profit margins, as well as meeting military and industrial demands.
USAC positions itself as the only fully integrated antimony company outside of China and Russia. Its operations span locations in the U.S., Mexico, and Canada, with a focus on both production and processing of critical minerals, setting it apart from other companies that may not have as expansive an operational footprint.
