AZTEC MINERALS INCREASES TOMBSTONE DRILLING PROGRAM BY 3,500 METERS

Aztec Minerals Corp.'s Tombstone property joint venture management committee has met recently and approved a further expansion of the continuing drill program by 3,500 metres of additional reverse circulation (RC) drilling. The expanded drilling program, which commenced in June, 2025, is now expected to total approximately 22,200 metres of combined core and RC drilling (18,829 metres RC and 3,371 metres core). The additional approved drilling budget totals $1.4-million and is expected to be directed toward targets in the North Contention area. The Northern Contention area is the continuation of the Contention target area with similar geology, mineralization styles and abundant historical underground mine workings from the historical period of 1878 to 1911. The focus of this additional shallow RC drilling program is to target oxide gold-silver mineralization.

Drilling program update: The continuing program has currently completed 14,162.5 metres of RC drilling over 68 drill holes and 3,371.1 metres of core drilling over nine drill holes. There are currently 14 RC drill holes shipped to the laboratory awaiting results and three core drill holes are either awaiting core cutting or shipment to the laboratory prior to results. The new Northern Contention area drill program is expected to continue through August, 2026, with results expected into the fourth quarter of 2026.

Investor relations contract: Aztec also announces it has contracted Redwood Empire Financial Communications, operated by Michael Bayes of Alpharetta, Ga., to provide corporate communications services to the company. The consultant will assist the company in developing and implementing investor communications and financial public relations with existing and prospective shareholders, brokers, dealers and other investment professionals. Certain of the services to be provided by the consultant under the agreement constitute investor relations activities within the meaning of the policies of the TSX Venture Exchange. Under the agreement, the consultant will receive a monthly consulting fee of $7,500 (U.S.) plus applicable taxes over the 12-month term and will be granted 300,000 stock options on such dates and with such terms as the company may determine.

To the company's knowledge, as of the date hereof, the consultant does not own any securities of the company and is arm's length to the company. The agreement is subject to approval by the TSX Venture Exchange.

Aztec Minerals will be participating in the following coming events and conferences:

• June 1 to 4: The Mining Investment Event, Quebec City, Que.
• Sept. 22 to 25: 2026 Precious Metals Summit Beaver Creek, Beaver Creek, Colo.

Tombstone project overview

Aztec Minerals holds an 85.0-per-cent interest in the Tombstone property joint venture, which includes most of the original patented mining claims in the main district as well as some recently acquired properties.

The main target of the current drilling is to continue testing the shallow, bulk-tonnage, potentially heap-leachable, mesothermal gold-silver oxide mineralization adjacent and below the previously mined Contention pit by stepout drilling. Future drilling is expected to focus on follow-up on the current program's results. It is anticipated that possible targeting could include strike and dip extensions of the shallow oxide mineralization and move along those trends deeper into the sulphide zone as historically there was significant production to 300 metres depth.

The Tombstone project is located 100 kilometres southeast of Tucson, Ariz., and covers much of the historic Tombstone silver district. Tombstone is renowned for its high-grade, oxidized, silver-gold mesothermal stringer lode veins, hydrothermal breccias and manto CRD (carbon replacement deposit) orebodies that were mined in the late 1800s and early 1900s. The historic silver production in the Tombstone district from 1878 to 1939 was estimated at 32 million ounces and 250,000 ounces of gold.

The district geology consists of a mix of shallow-level, oxidized gold-silver and base metal deposits related to CRD and skarns hosted in folded and thrusted sediments, intrusive dikes and lode veins, and as well the underexplored, sulphide versions located below the water table.

Host rocks to the mineralization are primarily the clastic sediments of the lowest portion of the Cretaceous Bisbee formation. Between 50 and 300 metres in depth, the Bisbee formation is underlain by approximately two kilometres thick of the same Paleozoic carbonate formations that host the Hermosa-Taylor zinc-lead-silver deposit of South32, located 60 kilometres southwest of Tombstone.

Aztec believes that the historic silver mines at Tombstone could be related to a much larger mesothermal system with CRD mineralization below the old mines. Since 2017, Aztec has completed geological mapping, geochemical sampling and geophysical surveying to identify the most prospective areas for gold-silver mineralization around and below the Contention open pit and CRD zinc-lead-copper-silver-gold mineralization below the entire district. Aztec management views the district as highly prospective for the discovery of mesothermal and CRD mineralization.

Summary tombstone project highlights:

• Well-located property on patented (46) and unpatented (73) claims (833 hectares/2,058 acres), covers much of the historic Tombstone silver mining district, great infrastructure, local town, road access, full services, water and power;
• Historic silver district produced 32 million ounces of silver and 250,000 ounces of gold from 1878 to 1939 in high-grade, oxidized, silver-gold-lead-zinc-copper vein, breccia and CRD deposits, and small open-pit heap-leach production in late 1980s;
• Drilling by Aztec in 2020 to 2025 has demonstrated that the Contention pit target has significant, shallow, oxidized gold-silver bulk tonnage mineralization, which is open in all directions;
• Multiple other prospective targets in Cretaceous and Paleozoic rocks related to major northwest- and north-northeast trending structures hosting porphyritic intrusions crosscutting a possible caldera ring structure.

Note: Aztec has not verified historic results and is not relying on them. Aztec has in its possession the historic drill logs, maps and reports but does not have any information on the quality assurance or quality control measures taken in connection with these historical exploration results.
