American Marconi Wireless News - American Antimony Corporation Confirms World-Class Intercept: 87 m (285 ft) @ 1.46% Sb, Including up to 5.59% Sb and 1.33 g/t Au, with Exceptionally Low Arsenic (<50 ppm), and Expands District-Scale Potential at the American Antimony Project, Bernice Canyon, Nevada

Drilling Program Summary

• 14 reverse circulation (RC) drill holes completed, totaling 5,570 feet (1,697.7 meters), with depths ranging 300-800 ft (61-232 m).

• 10 of 14 holes intersected the targeted felsite dike, confirming strong structural and geochemical continuity.

• Results include some of the thickest and highest-grade antimony zones documented in the U.S. in decades.

• The felsite dike swarm extends from the Arrance Mine through IHX and south to King Solomon, defining a continuous 3.2 km (2-mile) mineralized corridor.

Key Intercepts (Certified Lab Assays)

• BC25-03 - Arrance Core Zone ("Spectacular Intercept")

  • 87 m (285 ft) continuous felsite-hosted mineralization (103.6-190.5 m).

  • Average 1.46% Sb (14,600 ppm), up to 5.59% Sb, with many in-situ assays between 2%-3% Sb.

  • Gold up to 1.33 g/t Au; average 0.27 g/t Au across the interval.

  • Confirms vertical continuity of mineralization to ~500 ft depth.

• BC25-11 - Central Corridor

  • 12.3 m @ 1.06% Sb and 0.18 g/t Au (134.1-146.4 m).

  • Supports increasing grade and thickness with depth.

• BC25-02 - Arrance (Lower Adit)

  • 7.6 m @ 1.08% Sb with gold credits.

  • First laboratory-confirmed Sb intercept of the program.

• BC25-05 - Arrance True Width Test

  • 7.6 m @ 0.72% Sb and 0.33 g/t Au.

  • Confirms true dike width ~25 ft (7.6 m).

• BC25-01 & BC25-04 - Peripheral Step-Outs

  • Sb assays up to 0.39% Sb (3,893 ppm) with gold up to 0.43 g/t.

  • Confirm zoning and southern strike continuity.

Geological Insights & Global Comparatives

Drilling results confirm that felsite dike swarms are the principal host of stibnite (Sb₂S₃) mineralization at Bernice Canyon. This setting directly compares to two globally significant Sb systems:

• Xikuangshan Sb Deposit, China - The world's largest antimony deposit, Xikuangshan is similarly hosted in felsic dikes that acted as conduits for Sb-rich hydrothermal fluids. The Bernice Canyon intercepts, particularly BC25-03 (87 m @ 1.46% Sb), demonstrate thickness and grade on par with Xikuangshan's productive zones, underscoring Nevada's potential for large-scale, in situ antimony resources.

• Schlaining Ore District, Austria - A historic European producer that supplied antimony for over 200 years, Schlaining's mineralization is likewise dike-hosted, marked by quartz-carbonate-stibnite veining and disseminated stibnite along altered felsite contacts. Its longevity highlights the durability and economic importance of felsite-hosted Sb systems.

Together, these analogues confirm Bernice Canyon's felsite dike system-mapped over 3.2 km of strike length and open in all directions-is geologically consistent with some of the largest and most enduring antimony-producing regions worldwide.

Critically, arsenic values remain exceptionally low (, offering a metallurgical advantage for clean, market-ready concentrates.

Management Commentary

"These Phase One drill results mark a breakthrough moment for American Antimony/Xtra Energy," said Mac J. Shahsavar, P.Eng., Chairman & CEO. "Hole BC25-03 demonstrates the thickness and grade required to classify Arrance as a world-class antimony system. Combined with results across 14 holes, we now confirm district-wide continuity of felsite dike-hosted mineralization spanning at least 3.2 kilometers. The combination of scale, clean metallurgy, and associated gold credits positions us at the forefront of developing a strategically important U.S. domestic source of antimony."

Shahsavar added: "The Antimony King Mine, while not yet fully tested, represents a different style of mineralization with the potential to host an even larger deposit than the Arrance-IHX-King Solomon corridor. Importantly, only 4 of 22 historic mines on our claims have been tested to date-less than 8% of our 4,153-acre land package. Phase One drilling has covered just 330 acres, underscoring that the discovery potential at Bernice Canyon remains truly immense."
