XTPT announced that Western Frontier has completed an extensive field program designed to advance:

✅ Phase II drill planning
✅ Initial block modeling efforts
✅ District-wide access evaluations
✅ Infrastructure assessments across ~3.5 miles of mineralized strike

The work supports American Antimony's vision of developing Bernice Canyon as a district-scale antimony system rather than a single mine.

Recent field activities continue to integrate:

🔹 Historical workings
🔹 Photogrammetry-LiDAR models
🔹 Structural mapping
🔹 Future resource modeling
🔹 Infrastructure planning

With exceptional metallurgy, low arsenic levels, primary stibnite mineralization, and ~97% recoveries already demonstrated, American Antimony continues building a foundation for large scalable domestic antimony production.

CEO Commentary

"Our vision has always extended beyond a single mine," said Mac J. Shahsavar, P.Eng., Chairman and Chief Executive Officer of American Antimony Corporation.

"Western Frontier's latest field program continues to advance that vision by helping us define future drill targets, begin developing initial block models, and evaluate the infrastructure required to unlock the broader district. We believe these efforts further strengthen the foundation for long-term development and reinforce the significance of Bernice Canyon as the top emerging domestic antimony district."

XTPT / American Antimony Project continues to position itself at the center of one of the most important emerging U.S. critical mineral supply chain stories.

A strong recent article titled “Antimony at $50,000 per tonne: A Wake-Up Call America Can’t Afford to Ignore” highlights the growing global antimony crisis and why domestic U.S. supply is becoming increasingly important.

The article reinforces the reality that antimony is no longer just another industrial metal. It is now directly tied to:
• defense systems
• semiconductors
• energy infrastructure
• solar technologies
• flame retardants
• broader national security supply chains

As prices surge and foreign supply risks continue rising, projects capable of helping build a domestic antimony supply chain may become increasingly valuable moving forward.

That is why we believe the American Antimony Project continues gaining significance.

XTPT has already:
✅ confirmed large-scale stibnite mineralization
✅ reported major antimony intercepts in Nevada
✅ achieved strong flotation concentrate and recovery results
✅ advanced toward potential domestic refining pathways
✅ continued expanding the understanding of the Bernice Canyon district-scale system

In August 2024, China's Ministry of Commerce quietly announced export licensing requirements on antimony. It barely made headlines.

XTPT Q1 2026 Update – Building a Domestic Antimony Supply Chain 🇺🇸

🔗https://otcmarkets.com/file/company/financial-report/560580/content

Q1 2026 marked a major advancement period for American Antimony Corp. as the Company accelerated progress across metallurgy, operational planning, and strategic positioning within the growing U.S. critical minerals sector.

Metallurgical Progress

The Company successfully executed the first major milestone under its Metallurgical Testing Agreement (MTA), including delivery of ~400 kg of Nevada-sourced high-grade antimony ore for third-party testing.

ALS Metallurgy flotation testing returned strong initial results:

⚫️ ~30.3% Sb average head grade
⚫️ ~63% Sb concentrate produced
⚫️ ~97% antimony recovery

These results validated the ability to upgrade Antimony King material into high-grade concentrates using conventional flotation methods.

Operational Advancement

During the quarter, the Company completed a comprehensive site visit alongside Western Frontier Exploration & Mining focused on advancing the American Antimony Project toward potential production scenarios.

Key initiatives included:

⚫️ Advanced drone surveys
⚫️ High-resolution 3D modeling
⚫️ Stockpile analysis
⚫️ Operational mine planning
⚫️ Validation of historic workings

Q1 Milestone Summary

1⃣ Executed first MTA shipment and testing milestone

2⃣ Advanced ALS-led flotation and concentrate development

3⃣ Achieved ~63% Sb concentrate at ~97% recovery

4⃣ Advanced operational planning initiatives

5⃣ Continued positioning XTPT as a strategic U.S. antimony development story

American Corp. has initiated the Small Mine Permit process at the Antimony King Mine, marking an important step toward advancing the project.

This phase is designed to support:

▪️Surface material access and bulk handling
▪️Ongoing metallurgical optimization
▪️Preparation for near-term production activities
▪️Development of a scalable operational footprint

The permit process represents a key transition point as the Company moves from:

👉 Validation → Early-Stage Production Planning

Why This Matters ⤵️

The Antimony King Mine hosts:

▪️Previously identified high-grade surface material
▪️Proximity to existing infrastructure
▪️Alignment with the Company’s phased development strategy

Advancing permitting enables the Company to begin:

▪️Structured material movement
▪️Expanded sampling and processing
▪️Operational planning at scale

This milestone builds on recent progress, including:

▪️Successful metallurgical testing (97% recovery)
▪️High-grade head grade confirmation (30.3% Sb)
▪️Drill validation at the Arrance Mine

Initiating the Small Mine Permit process is a foundational step toward transitioning the project from validation into operational development.
