Aztec Minerals Increases Drilling Program by 4,500 Meters and Commences

Downhole Geophysical Survey of Core Holes at Tombstone Project, Arizona

News Release - Vancouver, Canada – March 10, 2026 - Aztec Minerals Corp. (AZT: TSX -V, OTCQB: AZZTF)

(“Aztec” or the “Company”) announces that the Tombstone Property Joint Venture Management Committee

met recently and approved a further expansion of the ongoing drill program by 4,500m of additional reverse

circulation (“RC”) drilling. The expanded drilling program which commenced in June 2025 is now expected

to total approximately 17,000m of combined core and RC drilling (14,200m RC and 2,800m core). The

additional approved drilling budget totals CAD$1.7 million and is expected to be directed towards targets in

the Westside, Hard -up, Ingersoll, East Contention, Southeast Contention, Central Contention and North

Contention Areas (please see figure 1 below). The focus of this additional shallow RC drilling program is to

target oxide gold-silver mineralization.

The company also announces the commencement of downhole Electromagnetic (“EM”) surveys of three core

holes at the property including the recently completed TC 25-3 hole in the North portion of the property,

TC25-4 which targeted the Southeastern NSAMT target, and TC 26-2 which is currently being drilled in the

Southwestern NSAMT target. Aztec has contract ed Zonge International to conduct the survey over the

month of March 2026. Geophysical data obtained by the downhole EM survey is expected to bolster

targeting for potential massive sulfide mineralization that may be hosted below the shallow Bisbee group

sediments that host the oxide gold-silver mineralized system at the Tombstone property.

Option and RSU Grant

The Company also announces the granting of Options under the Company’s Omnibus Equity Incentive Plan

(the “Plan”) to certain of its directors, officers and consultants to purchase up to an aggregate 4,300,000

common shares of the Company at a price of $0. 31 per share for a period of 5 years. These Options are

subject to certain vesting provisions.

Additionally, the Company has awarded a total of 1,000,000 Restricted Share Units (“RSUs”) under the Plan

to its directors, officers and selected consultants. The RSUs will vest over a period ranging of two years from

the grant date. Upon vesting, each RSU grants the holder the right to receive one common share of the

Company, or, at the discretion of the Company’s board of directors, may be settled in cash.

Tombstone Project Overview

Aztec Minerals holds a 85.0% 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 step -out 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 sulfide zone as histori cally

there was significant production to 300 m depth*2.

The Tombstone project is located 100 kilometers (km) southeast of Tucson, Arizona and covers much of the

historic Tombstone silver district. Tombstone is renowned for its high grade, oxidized, silver -gold

mesothermal stringer lode veins, hydrothermal brec cias and manto CRD orebodies that were mined in the

late 1800’s and early 1900’s. The historic silver production in the Tombstone district from 1878 to 1939 was

estimated at 32 million ounces and 250,000 ounces of gold*2.

The district geology consists of a mix of shallow-level, oxidized Au-Ag and base metal deposits related to CRD

and skarns hosted in folded and thrusted sediments, intrusive dikes, and lode veins, and as well the under

explored, sulfide 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 meters (m) in depth, the Bisbee is underlain by approximately two

kms thick of the same Paleozoic carbonate formations that host the 110 MT Hermosa-Taylor zinc-lead-silver

deposit of South32 located 60 km southwest of Tombstone*3.

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 Au -Ag

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 (33) and unpatented (73) claims (663 hectares / 1639 acres),

covers much of the historic Tombstone silver mining district, great infrastructure, local town, road

access, full services, water, power

• Historic silver district*2 produced 32 million ounces of silver and 250,000 ounces of gold from 1878-

1939, in high grade, oxidized, silver-gold-lead-zinc-copper vein, breccia and CRD deposits, and small

open pit heap leach production in late 1980’s

• Drilling by Aztec in 2020-25 has demonstrated that the Contention Pit target has significant, shallow.

oxidized Au-Ag bulk tonnage mineralization which is open in all directions

• Multiple other prospective targets in Cretaceous and Paleozoic rocks related to major NW and NNE

trending structures hosting porphyritic intrusions crosscutting a possible caldera ring structure

* Aztec has not verified these 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.
