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

Strongly recommend reading the article below for anyone following the future of critical minerals in America:

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

Key initiatives included:

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

CEO Commentary

"This is a major step forward in how we understand and advance the Antimony King system," said Mac J. Shahsavar, P.Eng., Chairman and Chief Executive Officer of American Antimony Corporation.

"We are no longer working from fragmented datasets — we now have a high-resolution photogrammetry–LiDAR model that gives us a clear, spatially accurate view of the system. That level of detail is critical as we move into mine planning, permitting, and ultimately toward scalable domestic antimony production."

American Antimony has engaged Western Frontier Exploration & Mining to advance:

• Structural mapping
• 3D geological modeling
• Small mine planning at Antimony King

The focus here is integrating surface data, underground access, and drone mapping into a single cohesive model to support mine planning and evaluate staged development scenarios.

This marks the shift from technical validation toward operational planning, building on previously reported metallurgical results.

Q4 2025 marked a transformative period for American Antimony Corp. as we advanced the American Antimony Project through multiple key milestones across exploration, metallurgy, and development.

Exploration Success – System Scale Confirmed

During the quarter, drilling confirmed a significant intercept of 87 meters (285 feet) grading 1.46% antimony, including higher-grade intervals up to 5.59% Sb and associated gold values of 1.33 g/t. These results support the presence of a continuous mineralized system and reinforce the project’s potential at scale.

Metallurgical Advancement – From Rock to Recoverable Product

The Company executed a Metallurgical Testing Agreement (MTA), initiating the next phase of development focused on recoverability and processing optimization.

As part of this program, a ~400 kg bulk sample of high-grade antimony material sourced from Nevada was delivered and processed.

Results – Strong Recovery and Concentrate Quality

Initial metallurgical results returned:

⚫️ ~30.3% Sb average head grade
⚫️ Production of ~63% Sb concentrate
⚫️ ~97% recovery

These results demonstrate the ability to efficiently upgrade surface material into a high-grade, sale-able concentrate using conventional processing methods.

Q4 Milestone Summary

Throughout the quarter, the Company successfully:

1⃣Confirmed significant mineralized thickness and continuity

2⃣Advanced from exploration into metallurgical validation

3⃣Delivered and processed bulk material

4⃣Demonstrated strong recoverability and concentrate quality

Positioning for 2026

With these results, American Antimony Corp. has taken meaningful steps toward establishing a domestic antimony supply pathway. The combination of scale, grade, and metallurgical performance positions the project for continued advancement as we move into the next phase of development.

On behalf of the Company, we thank our shareholders for their continued support as we build what we believe to be a significant U.S.-based antimony asset.
