Arizona Tribune - Major Antimony Deposit Discovered: American Antimony Corporation (Operating as Xtra Energy Corporation) Confirms Thick, High-Grade Antimony-Gold Dike System at Arrance Mine

AUSTIN, TX / ACCESS Newswire / August 11, 2025 / Xtra Energy Corporation (OTC PINK:XTPT), a U.S. based company dedicated to securing antimony, a critical mineral vital to national security for its use in defense, semiconductors, and energy storage, is pleased to provide its preliminary drilling report from the Arrance Mine, part of the flagship 4,194 acre American Antimony Project in Nevada's historic Bernice Canyon District.

Investors are cautioned that these results are preliminary, based primarily on visual logging and portable XRF field analysis, and remain subject to confirmation by certified third-party laboratory assays. Samples have been delivered to American Assay Laboratories in Reno, Nevada, and final results will be released following analysis and review by Company geologists.

Program Overview
The initial Arrance Mine drilling program consisted of five reverse circulation (RC) drill holes targeting the main felsite dike structure. Of the five holes drilled, four intersected significant stibnite mineralization, and three holes also returned notable gold values from portable XRF screening. The work confirms the presence of a thick, steeply dipping, stibnite-bearing felsite dike system with encouraging gold credits.

Drill Highlights

Hole BC25-02 - First Visual Confirmation of In-Situ Stibnite

• Collar: Lower adit area, Arrance Mine

• Dip: -45°

• Dike intercept: 115-140 ft (25 ft)

• Strong, continuous stibnite mineralization throughout; intense QSP alteration

• Represents first visual confirmation of in-situ mineralized felsite dike

Hole BC25-03 - "Spectacular Intercept"

• Same pad as BC25-02; drilled at -20° dip

• Dike intercept: 340-625 ft (285 ft continuous)

• Strong stibnite mineralization throughout; intense alteration

• Preliminary geometry: ~630 ft downhole (~500 ft vertical)

• Gold (pXRF):

  • 10 ft @ ~80.5 g/t Au (520-530 ft), including 5 ft @ 107 g/t Au

  • 5 ft @ 190 g/t Au (565-570 ft)
    

• Visible gold confirmed in both high-grade intervals

• Arsenic levels are low and well below deleterious thresholds

Hole BC25-04 - South Step-Out

• Located ~150 ft (50 m) south of BC25-02/03

• Dike intercept: 110-145 ft (35 ft)

• Visual Sb present; represents southern strike continuity of the dike

Hole BC25-05 - True Width Confirmation

• Drilled between BC25-02 and BC25-03, opposite azimuth to measure true width

• Dike intercept: 440-465 ft (25 ft)

• Widespread disseminated stibnite and strong alteration

• Estimated true width: 30-45 ft

Hole BC25-01 - Northern Periphery Test

• Encountered felsite dikes at 30-65 ft and 205-225 ft

• No significant visible stibnite; interpreted as peripheral alteration zone

Key Points

• Drilling confirms a thick, steeply dipping, stibnite-bearing felsite dike at Arrance Mine

• True width estimated at 30-45 ft

• Apparent down-dip continuity of 285 ft in BC25-03, one of the thickest such intercepts documented in a U.S. Sb system in decades

• Bonanza-grade gold (107 g/t and 190 g/t Au) in distinct zones within the dike

• Low arsenic levels (

Management Commentary
"The results from Arrance are extremely exciting," said Mac J. Shahsavar, P.Eng., Chairman & CEO of Xtra Energy. "We have confirmed both the thickness and continuity of the mineralized dike, with visible stibnite and exceptionally low arsenic, plus the added benefit of bonanza gold zones. This combination of scale, grade, and metallurgy is rare in antimony systems. Inspired by recent government support for critical mineral projects, such as the U.S. Department of Defense's multibillion-dollar investment in MP Materials and the $24.8 million award to Perpetua Resources for antimony processing with FAST-41 permitting support, we look forward to advancing the Arrance project toward defining a domestic, world-class critical mineral resource that has the ability to help the U.S. with its national security interests."
