American Marconi Wireless News - United States Antimony Announces Critical Mineral Acquisition Fostung Tungsten Property Ontario, Canada

DALLAS, TX / ACCESS Newswire / June 27, 2025 / United States Antimony Corporation ("USAC," "US Antimony," the "Company"), (NYSE American:UAMY), announced today that it has completed an acquisition of 100% of the ownership interest of the Fostung Properties which cover fifty (50) single-cell mining claims or 1,114 hectares located approximately 70 kilometers west-southwest of Sudbury, Ontario, Canada, near the town of Espanola. The total purchase price of the tungsten properties was $5 Million in cash in addition to a ½ of 1% (0.005) Net Smelter Return royalty (NSR) interest to be divided equally between the sellers; Transition Metals Corp (XTM-V) and 1930153 ON Ltd (a Private Company). There exists an additional NSR of 1% (0.010) held by a previous owner.

TUNGSTEN
Tungsten's unique properties, which include a high melting point, density, hardness, and conductivity, make it indispensable in many sectors which include:

• Aerospace (kinetic energy penetrators)

• Defense (shielding of tanks and counterweights)

• Electronics (semiconductors, x-ray tubes)

• Tooling & Manufacturing (high speed cutting tolls and drills)

• Energy (Electrodes and arc welding)

• Medical (Radiation shielding)

SUPPLY
China controls the vast majority of worldwide tungsten supply and controls 80-85% of global processing capacity. China also consumes a large share of the tungsten it produces, further tightening global availability. There has been no known commercial production of tungsten concentrates in either the USA or Canada since 2016, nine years ago. A tungsten shortage has begun developing worldwide as record tungsten new prices continue their upward trend. Reduced global production along with a lack of supply from China has been exacerbated due to the February 2025 export restrictions. The value of Tungsten used in both the USA and Canada exceeds $1 Billion annually.

PROCESSING
Sudbury is the premier mining region of Canada so there is potential to use existing milling infrastructure. Recent work by the property vendors has shown that modern ore sorting processing methods, utilizing the fluorescent and other unique properties of the tungsten minerals, can upgrade the ore. We plan to continue this work and assess other techniques to determine the possibility of fine crushing on site, followed by concentration to yield an upgraded product that could be trucked to existing mills or tungsten plants in Canada or possibly in the USA. Conventional froth flotation milling at a plant in close proximity to the deposit will remain as the back-up option.

GEOLOGY & RESOURCES
The Fostung deposit occurs in the Espanola Formation, which is part of the Huronian succession (2.1 to 2.5 billion years old) meta-sediments of the north shore of Lake Huron geology and is similar to the geology at our Iron Mask Cobalt Property (See Press Release dated August 13, 2024) located about 65 kilometers (40 miles) northwest of Sudbury and acquired last year. Previous work on Iron Mask has concentrated on showings of high-grade cobalt, nickel, copper, and bismuth.. At Fostung a inferred resource of 12.4 million tonnes (13.7 million US tons) grading 0.213% tungsten trioxide (WO3) at a 0.125% tungsten trioxide cut-off grade has been calculated in compliance with Canadian National Instrument 43-101 standards and was previously published by SRK Consulting. The company plans to commission an updated report compliant with SEC SK 1300 regulations, that includes the results of recent drill programs conducted by the property vendors.

Commenting on today's announcement, Mr. Joseph Bardswich, P. Eng., Executive Vice President and Chief Mining Engineer for USAC, stated, "Our first significant acquisition of a Tungsten deposit fits well within our company policy of only seeking mineral deposits that we believe can be quickly and inexpensively developed. The location of the Fostung property, close to both the Town of Espanola, the Sagamok First Nation, the Whitefish River First Nation and the Whitefish First Nation, provides opportunities for acquisition of supplies, equipment, contractors, and experienced personnel. Good road access and proximity to electrical power are added benefits. While we recognize that there is considerable work to be done before production can be considered, this proximity to significant infrastructure and the potential for an early open pit mining operation, makes Fostung our Company's first Tungsten choice."

TUNGSTEN HISTORICAL PRICE COMPARISON
USAC has analyzed data from May 2021 through June 2025, highlighting consistent price elevation in Chinese tungsten material delivered to the U.S. due to logistics, tariffs, and export controls. Meanwhile, Rotterdam-based pricing-converted to $/lb for comparison-remains more stable but equally affected by European market dynamics. This price volatility underscores the strategic importance of secure, domestic sources of tungsten as well as other critical minerals. The analysis compares prices of Chinese tungsten bars delivered to the United States against ingot prices from the Rotterdam market over a four-year period from May 2021 to June 2025. The data reveals sustained pricing volatility, with Chinese tungsten consistently carrying a premium due to delivery costs, tariffs, and increased export restrictions under China's tightening critical mineral policies.
