With Small-Mine Development Underway, American Antimony Advances Historic Roadwork to Reconnect Past-Producing Mines at Bernice Canyon Strike

Austin, Texas--(October 19, 2026) - American Antimony Corporation (OTCID: XTPT), operating as Xtra Energy Corp. ("American Antimony" or the "Company"), today announced the advancement of a district-wide road restoration and rehabilitation initiative at its flagship American Antimony Project in Bernice Canyon, Nevada. The initiative is intended to reestablish access to additional historic producing mines, prospects and mineralized areas beyond the Company's core Arrance and Antimony King exploration areas, supporting expanded exploration, geological evaluation and the potential identification of additional antimony, gold and silver mineralization across approximately 3.5 miles of historic strike.

Improved Road connectivity would also allow technical teams to revisit past-producing mines and historic workings, evaluate large stockpiles and underexplored targets, extend mapping and sampling programs along with potential future resource expansion beyond the world-class potential already identified Antimony deposits at Arrance and Antimony King.

Rather than establishing an entirely new network, the Company proposes to repair and rehabilitate existing historic mining roads and access corridors. Improved connectivity would allow technical teams to revisit past-producing mines and historic workings, evaluate stockpiles and underexplored targets, extend mapping and sampling programs, and assess opportunities for additional antimony mineralization, historically reported gold and silver occurrences, and potential future resource expansion beyond the world-class potential already identified at Arrance.

Decades of erosion, weathering, washouts and limited maintenance have left portions of the district's historic road network difficult or unsafe to traverse. Restoring these previously established routes is intended to improve project logistics and field safety while minimizing unnecessary new surface disturbance, subject to applicable approvals.

Project-Wide Access Through Existing Infrastructure

The purpose of restoring the historic road network is broader than improved transportation: practical access is a prerequisite for systematically evaluating additional past-producing mines and exploration targets throughout Bernice Canyon. The district-scale map below shows how the completed core-area access and proposed rehabilitation routes relate to historic mine areas beyond Arrance and Antimony King.

As illustrated above, Phase I (in blue) restoration established reliable access through the Company's core Antimony King, King Solomon and Arrance exploration areas. The proposed Phase II (in red) restoration would extend that strategy across the broader historic road network, reestablishing access toward Hoyt and U-Bet to the northeast and the Marguerite Group, Drumm and Blue Eagle areas to the south.

Importantly, the proposed Phase II routes utilize pre-existing roads and access corridors established through historical mining activity, allowing the Company to pursue district-wide connectivity through restoration of existing infrastructure rather than development of an entirely new road network.

Recent field evaluations by Western Frontier examined these historical access routes and identified areas where repair and rehabilitation could restore practical access to additional mines, prospects and exploration targets, with particular attention given to routes toward the Blue Eagle area and along the historic Hoyt Road corridor.

Management believes that restoring these connections could enable systematic examination of additional historic producers and underexplored mineralized areas across approximately 3.5 miles of strike. This work may help identify extensions, parallel targets and other opportunities for future resource-definition programs, building upon the drilling results at Arrance.

Reestablishing Access Across 3.5 Miles of Historic Mining and Mineralization

Bernice Canyon is not defined by a single historical mine. Numerous historic antimony mines, prospects, workings and mineralized areas occur throughout the broader property position. Reestablishing access would enable field teams to evaluate these locations directly and determine which merit follow-up sampling, mapping, drilling or other technical work.

The proposed restoration program is designed to reconnect approximately 3.5 miles of this historically mineralized corridor, extending from the Company's established Antimony King and Arrance exploration areas toward historic mine and prospect areas associated with Hoyt, Marguerite, Drumm, Blue Eagle and U-Bet.

Restoring these existing corridors is expected to improve operational flexibility and support Phase II and future drilling, geological mapping and sampling, historic mine and stockpile evaluation, equipment mobilization, environmental programs, potential resource-definition work and future mine planning, subject to applicable permitting and regulatory approvals.

Building Upon Successfully Completed Phase I Roadwork

American Antimony's initial infrastructure program established the practical access necessary to execute its Phase I drilling campaign.

In June 2025, the Company announced final approval from the U.S. Bureau of Land Management ("BLM") for road construction and drilling activities at the American Antimony Project. The approved program included approximately 2,790 feet of constructed road, 4,920 feet of overland travel and 12 drill pads.

The completed infrastructure supported Phase I drilling, geological investigation, sampling and subsequent technical programs within the Company's core exploration area.

With core-area access established through the previously approved Phase I program, the Company is now seeking to restore the wider historic road network that once connected additional mining operations throughout Bernice Canyon.

Improving Safety and Accessibility

The benefits of restoring Bernice Canyon's historical road network extend beyond American Antimony's exploration activities.

Repairing deteriorated roadbeds, washouts and unsafe sections can improve travel conditions along existing routes. Where available for lawful public or third-party use, restored roads could also improve accessibility for land-management personnel, emergency responders, recreational users and other authorized users of the area.

The Company believes rehabilitation of previously established access corridors represents a practical approach to improving project logistics and public safety while responsibly utilizing infrastructure already present within the district.

CEO Commentary

"Alongside our ongoing focus on establishing initial small-mine operations at Arrance and Antimony King, we have initiated efforts to restore the historic Bernice and Hoyt mining-road networks. This work is intended to provide access to additional historic mines across our property and allow us to begin systematically exploring areas such as Hoyt, Marguerite, Drumm, Blue Eagle, U-Bet and other historic workings throughout the district.

Historical records indicate the potential for significant silver and gold mineralization in addition to antimony across portions of these areas. Our objective is to build upon the work already underway at Arrance and Antimony King while opening up the broader district for further exploration and potential resource expansion.

At the same time, repairing these deteriorated routes can improve safety and accessibility for others who lawfully use the area."

- Mac J. Shahsavar, P.Eng., Chairman and Chief Executive Officer

Restoring a District, Not just a Mine - Reestablishing Access to a Historic Antimony District

Bernice Canyon supported antimony mining and production activities long before American Antimony's modern exploration program.

Historical accounts dating to the early 20th century document Bernice Canyon as an established antimony-producing district. Generations of exploration and mining resulted in numerous mines, prospects, workings, stockpiles and the access roads necessary to connect them.

Many of these historical roads remain identifiable today but have deteriorated after decades of limited maintenance.

The Company's proposed work is focused on repairing and rehabilitating these pre-existing historical road alignments. Where permitted and appropriate, activities may include repairing eroded or washed-out sections, restoring deteriorated roadbeds, removing obstructions, improving drainage and stabilizing unsafe sections.

The objective is to responsibly restore infrastructure that historically served the Bernice Canyon mining district while minimizing the need for unnecessary new surface disturbance.
