A2GOLD DETAILS ANTIMONY POTENTIAL INCLUDING PAST HIGH-GRADE PRODUCTION AND MINERALIZATION STYLES AT TAYLOR

A2 Gold Corp. has provided additional technical detail on the antimony potential at its Taylor gold-silver project in White Pine county, Nevada, including historical production data, mineralization styles and regional context.

This release builds on the company's March 17, 2026, news release and highlights the emerging significance of antimony mineralization at Taylor within the broader context of a district-scale mineralizing system.

Multiple styles of antimony mineralization support district-scale potential

Previous geological work at Taylor has identified two distinct styles of antimony mineralization:

• Tetrahedrite-rich mineralization associated with carbonate replacement deposit systems proximal to the Taylor resource; and
• Stibnite-stibiconite mineralization occurring distally, commonly stratiform and spatially associated with gold mineralization.

The co-existence of these mineralization styles across the property suggests a large, evolving hydrothermal system with potential for multiple mineralizing events and metal zonation.

Importantly, tetrahedrite-bearing CRD mineralization is consistent with, but does not confirm, a potential genetic link to an underlying intrusion-related (porphyry) system. Recent airborne magnetic and ground induced polarization surveys conducted by White Pine Metals have identified multiple geophysical targets consistent with this interpretation.

High-grade historical production demonstrates strong antimony endowment

Two past-producing antimony mines occur within the Taylor property and demonstrate the presence of exceptionally high-grade antimony mineralization.

Enterprise mine (1939 to 1941);

• 13 tons at 56 per cent Sb (1939);
• Six tons at 39 per cent Sb (1940);
• One ton at 76 per cent Sb (1941).

Mineralization occurs in narrow veins and replacement zones within silicified limestone, with stibnite developed as blades, needles and pods, commonly oxidized near surface.

Merrimac mine (1959 and 1960):

• Approximately 90 tons of ore averaging approximately 14 per cent Sb;
• Approximately 2.5 tons of antimony oxide produced.

Mineralization occurs as stibnite (commonly oxidized) in blebs, pods, veinlets and rosettes of bladed crystals distributed along favourable stratigraphic horizons with localized high-grade shoots. These grades, including samples up to 76 per cent Sb, rank among the highest reported antimony grades in Nevada and confirm the presence of a robust antimony-bearing system within the property.

Historical production data are derived from Nevada Bureau of Mines publications and other historical sources and have not been independently verified. While not compliant with National Instrument 43-101 standards, these data demonstrate the presence of high-grade antimony mineralization on the property.

Regional context highlights emerging antimony belt in eastern Nevada

Taylor is located within a broadly mineralized region hosting multiple styles of antimony mineralization, including:

• Porphyry systems (for example, Robinson district near Ely), where antimony occurs as a consistent accessory metal in large copper-gold systems; and
• Carlin-type systems (for example, Bald Mountain), where antimony is associated with gold mineralization in similar Paleozoic host rocks.

Recent exploration results from Nevgold Corp. at its Limousine Butte project (approximately 85 kilometres northwest of Taylor) have reported near-surface, oxide-hosted antimony mineralization associated with sediment-hosted gold systems in comparable geological settings.

While results from other properties are not necessarily indicative of mineralization at Taylor, they highlight increasing industry recognition of gold-antimony associations across Nevada and support the interpretation that White Pine county and the surrounding region represent an emerging and underexplored antimony-bearing belt.

Exploration implications and next steps

The presence of multiple antimony mineralization styles, high-grade historical production, widespread regional occurrences and geophysical evidence of potential intrusive centres supports the interpretation that Taylor represents a district-scale mineralized system. This system may include:

• Carbonate replacement mineralization;
• Distal gold-antimony mineralization;
• A potential underlying intrusion-related source.

The company is currently advancing drill targeting to test these concepts, with coming exploration programs designed to evaluate the relationship between antimony mineralization, gold systems and potential intrusive drivers.

Peter Gianulis, chief executive officer of A2 Gold, commented: "The Taylor project continues to evolve as a compelling multimetal system with clear district-scale potential. The presence of multiple styles of antimony mineralization, combined with exceptionally high-grade historical production, reinforces our view that Taylor hosts a large and dynamic mineralizing system. At a time when antimony is emerging as a critical mineral with constrained global supply, we believe Taylor represents a unique opportunity to advance a U.S.-based gold and critical minerals project. Our upcoming exploration programs are designed to systematically test these targets and unlock additional value for shareholders."

Strategic importance of antimony

Antimony is classified as a critical mineral by the U.S. government due to its importance in defence, energy storage and industrial applications, combined with limited domestic production and significant reliance on foreign supply. The identification of multiple styles of antimony mineralization at Taylor positions the project as a potential United States-based source of both precious metals and critical minerals.

About A2 Gold Corp.

A2 Gold owns three highly prospective gold projects in the United States, all of which are in the mining-friendly jurisdiction of Nevada. A2 Gold's flagship, district-scale Eastside gold-silver project hosts a large and expanding gold and silver resource, and is in an area of excellent infrastructure. Preliminary metallurgical testing indicates that both oxide and sulphide gold mineralization at Eastside is amenable to heap leaching.
