Aztec Completes Consolidation of Tombstone Gold-Silver District Land

Package, Arizona — Key Land Holdings Have Grown More Than Six-

Fold Since 2017

• Final agreement signed to acquire certain parcels totalling approximately 241 acres of surface rights and

approximately 414 acres of mineral rights across thirty historic patented lode claims

• Tombstone land position has grown from ~398 acres at the original property option in December 2017

to approximately 2,500 acres of mineral and surface rights upon closing of this most recent transaction

• Entire multi-transaction consolidation program completed for approximately US$500,000 in cash —

approximately US$1,250 per surface acre, with no share dilution and no finder’s fees

Vancouver, British Columbia – August 26, 2026 - Aztec Minerals Corp. (AZT: TSX-V, OTCQB: AZZTF) (“Aztec” or the

“Company”) announces that, through its wholly -owned subsidiary Aztec Minerals America Corp., it has signed a

definitive purchase and sale agreement (the “Agreement”) to acquire the final parcels of its Tombstone district land

consolidation program in Cochise County, Arizona. Upon closing, the Tombstone property will total approximately

2,500 acres across the heart of one of America’s most storied and prospective gold -silver districts — more than six

times the 398 acres of patented and unpatented claims under option when Aztec first came to the district in

December 2017.

The Agreement, with private vendors at arm’s length to the Company, covers certain parcels totalling approximately

241 acres of surface rights and 414 acres of mineral rights associated with various patented mining claims*, and

includes such historic patented lode claims as the Lucky Cuss, Old Guard, Owl’s Nest, Black Hawk, Grand Dipper, and

East Side for cash consideration of US$241,000. With respect to certain mineral -estate interests, the vendors are

conveying any and all of their right, title and interest. Closing is subject to customary conditions, including title

review and curative matters.

Aztec Minerals CEO Simon Dyakowski commented: “When we optioned Tombstone in December 2017, the project

covered 398 acres. Today, after years of strategic staking, claim purchases and the land consolidation program

completed with this agreement, our district position stands at approximately 2,500 acres — more than six times the

ground we started with. Our team consolidated that ownership, for a total cash outlay that we believe represents

exceptional value, and with surface access secured and the land pack age unified, we can now expand the modern,

systematic exploration in this district.”

Consolidation Program Summary

The Agreement completes a series of transactions undertaken by the Company since late 2025:

• January 2026 (closed May 11, 2026) – Acquisition from private vendors of two key parcels adjacent to the

North Contention pit, together with any known and associated mineral -estate interests, for US$88,000,

including resolution of an active tax-lien foreclosure and multiple legacy encumbrances. First step-out

drilling on this newly acquired ground was reported in early August, headlined by 88.4 m averaging 1.42

g/t Au and 14.58 g/t Ag (1.69 g/t AuEq) in hole TR26-39 (please see news release dated August 5, 2026).

• May 2026 – Acquisition of approximately 90 acres of patented claims, including the Emerald, Bunker Hill,

Silver Plume, Verde and Revenue claims, through the purchase and subsequent foreclosure of a secured

promissory note (total cost approximately US$124,000).

• July 2026 – Settlement and release agreement with a 3rd party for US$25,000.

• The Agreement announced today, covering the remaining parcels for US$241,000 + back taxes.

Aggregate cash consideration for the program is approximately US$500,000, at an average of approximately

US$1,250 per surface acre. All transactions were arm’s-length; no shares were issued and no finder’s fees were paid.

By comparison, the Company paid a pproximately US$3,360 per acre for the Westside patented claim in May 2023

and approximately US$1,750 per acre for the Alps and Minett claims in 2020.

Ownership Structure

All acquisitions under the consolidation program were made by Aztec’s wholly -owned subsidiary, Aztec Minerals

America Corp. Aztec’s Tombstone Joint Venture partner, Dragoon Resources LLC, has contributed its 15% share of

acquisition costs for all completed acquisitions under the program, which accordingly form part of the Tombstone

Joint Venture (85.0% Aztec / 15.0% Dragoon). With respect to the parcels covered by the Agreement announced

today, Dragoon holds a 60 -day right to participate on the same basis, which the Company expects to be exercised;

the Company will confirm the final owne rship structure in due course. Should the participation right not be

exercised, the parcels will be retained 100% by Aztec, adjoining the Tombstone Joint Venture property.

*Note that in the USA Split Estate (Mineral, Surface) Ownership of property can occur. The majority of the Tombstone Project

includes combined mineral and surface rights, with certain claims having split surface and mineral rights.

Land position figures reflect the Company’s current compiled land tenure database and may differ from figures reported in

earlier news releases due to claim lapses and re-stakings, boundary surveys, split-estate (mineral/surface) accounting and

differences in compilation methodology.

Exploration Momentum on the Acquired Ground

The consolidation is translating directly into exploration results. The North Extension Zone step-out drilling reported

on August 5, 2026 — highlighted by 88.4 m averaging 1.42 g/t Au and 14.58 g/t Ag (1.69 g/t AuEq) in TR26-39 — was

drilled on ground acquired under the consolidation program (please see news release dated August 5, 2026). Ninety

RC holes have been completed in the 2025 –2026 program; assay results are pending for holes TR26 -40 to TR26-50

and are expected in the coming weeks. Results are exp ected to be incorporated into the Project’s maiden mineral

resource estimate expected in the fourth quarter of 2026. Metallurgical test work is underway at Kappes, Cassiday

& Associates, a firm specializing in providing process metallurgical services to t he international mining industry,

located in Reno, Nevada.

Tombstone Project Overview

Aztec Minerals holds an 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 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 brecc ias 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**.

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 disco very of mesothermal and CRD mineralization.

** Aztec has not verified these historic results and is not relying on them. Aztec has in its possession the historic drill l ogs, maps

and reports but does not have any information on the quality assurance or quality control measures taken in connection wi th

these historical exploration results. Reference: Greeley, Michael N., A Brief History and Review of Ore Grades and Production in

the Tombstone Mining District with Emphasis on the Contention Mine Area, June 1984.
