VANCOUVER, BC / ACCESS Newswire / October 22, 2026 / Aztec Minerals Corp. (TSXV:AZT)(OTCQB:AZZTF) ("Aztec" or the "Company") announces the results from nine drill holes (TR26-45 to TR26-53) from its reverse circulation ("RC") portion of the 2025-2026 drilling program at the Tombstone Property in Southeastern Arizona. All nine holes intersected oxide gold-silver mineralization. Six holes (TR26-45 to TR26-49 and TR26-51) stepped out approximately 90 m to 190 m west of the North Extension holes reported on September 2, 2026, TR26-50 was drilled at a steeper angle from the TR26-41 pad, and TR26-52 and TR26-53 tested the zone north of TR26-43.
The western step-outs extend the known oxide footprint approximately 190 m west of the North Extension, and the mineralization remains open to the west, north and at depth. The Au-Ag mineralization found thus far in the North Extension shows the same controls as the Main Contention zone, i.e., variably altered and mineralized dioritic dikes channeling the strongly mineralized hydrothermal breccias with acutely angled mineralized quartz fissure lodes together cutting the Bisbee Group and lower carbonate sediments, often mineralized with large horizontal dimensions.
The maiden Mineral Resource Estimate ("MRE") for Tombstone, being prepared by APEX Geoscience Ltd., is expected in November 2026 and will incorporate drill results up to TR26-44. Assay results are pending for a further 22 RC holes (TR26-54 to TR26-75), including the remaining holes in the North Extension, which will be reported as they are received and reviewed.
Aztec Minerals CEO Simon Dyakowski commented: "This round of step-out drilling shows the oxide gold-silver system continuing west of the North Extension and at depth. TR26-45 returned more than 115 meters of continuous mineralization, and TR26-49 and TR26-51 added higher-grade intervals on the western side of the target. The system remains open to the west and at depth. Together with the pending results, these holes will help guide follow-up work in 2027, which will be planned once the maiden resource estimate is complete. We look forward to reporting the remaining results as they are received."

Note 1: Gold and Silver equivalents are calculated using the recovery percentages from third party metallurgical testing of RC drill pulps completed January 21, 2026 (81.5% for Au and 75.9% for Ag) and the average prices from January 1, 2026 to May 1, 2026 (US$4,817/oz Au, US$81.36/oz Ag), a price ratio of 59.2:1. Adjusted for the difference in metal recoveries, a 55:1 silver:gold ratio was used for the holes reported in this release. AuEq has been reported at 70:1 for November 2025 to February 2026, 90:1 in 2025 prior to November, 80:1 in 2023 and 2024, and a 70:1 silver:gold ratio in 2021.
2025-2026 Drill Program
The 112 RC drill holes completed to date in the current 2025-26 program are primarily part of a "fan grid pattern" being drilled in the Contention zone. Most of the RC drill holes are oriented to test for extensions on the western, eastern borders, the southern extensions, and underneath the north-trending main Contention target zone which hosts the historic underground and open pit Contention mine. Several RC drill holes tested targets in the Westside and Hard Up areas on projected anticline, dike and fissure vein intersections under mineralized outcrops and historic shafts. The drill program has continued to identify to depth and horizontally pervasively oxidized and hematite-rich, silicified hydrothermal breccias composed of quartz feldspar porphyry dike and Bisbee Group clastic sedimentary fragments, typical of the material mined historically at the Contention Mine.
Additional mineralization types continued to be outlined by the current drilling including: manganese replacements in limestone beds and skarns, quartz veinlets, oxidized sulfide relicts as disseminations, silicification of altered hornfels, quartz feldspar porphyries and hydrothermal breccias.
The primary objectives of the 2025-26 drilling program were to: Expand the known mineralization horizontally to the west, north and south, and down dip beyond the holes drilled by Aztec in 2020-24 at the Contention Pit with step outs to enlarge the shallow, broad, bulk tonnage gold-silver mineralization discovered there; test by core drilling the initial deep CRD targets and also, to explore with first pass drilling new targets identified in the Westside area. The drilling results showed that the Contention area mineralization is still open at depth and the mineralized volume is expanding.

The continued, successful drilling of the Contention pit area was supported by Aztec's 3D geologic and underground workings model that was constructed to assist in targeting potential expansion of the Contention system. The overall Contention system has yet to be defined and marks the confluence of other mineralized zones including the Westside Anticline.
Drill samples are collected every 1.52 m from RC chips and every 1.5 m from sawing the core drill holes. Samples from holes TR26-45 to TR26-53 were analyzed by Skyline Assayers & Laboratories in Tucson, Arizona (ISO 17025 / ISO 9001), which is independent of the Company and of the Qualified Person. Gold was analyzed by fire assay with AAS finish (FA-01), and samples exceeding 5,000 ppb Au were re-analyzed by fire assay with gravimetric finish (FA-02). Silver and multi-elements were analyzed by aqua regia digestion with ICP-MS (TE-3). The Company uses quality assurance-quality control as a standard part of its sampling-assaying-assessments in conjunction with its exploration sampling programs. Samples and their collection are controlled by an industry standard conforming QAQC program including all drill holes containing certified blanks, standards, and duplicates. Samples from hole TR26-63 onward are being analyzed by Bureau Veritas Minerals, with gold assays completed in Hermosillo, Mexico and multi-element analyses in Vancouver, Canada. The QAQC for the holes reported in this release has been evaluated and found to have good results.
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 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. Follow-up drilling is anticipated in 2027, with the program to be defined following completion of the maiden MRE. 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 historically 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 breccias 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 Hermosa-Taylor zinc-lead-silver deposit of South32 located 60 km 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 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 (46) and unpatented (73) claims (844.17 hectares/2,086 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 2020-26 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.
