    • Confirms Wide High-Grade Gold and Silver Oxide Mineralization on Surface
    • Field work and sampling are providing key assay results to expand the wide mineralized zone to surface and along strike
    • Additional continuous chip channel and reconnaissance sample assay results are pending

    VANCOUVER, BC / ACCESSWIRE / June 24, 2024 / Aztec Minerals Corp. (TSX-V:AZT)(OTCQB:AZZTF) ("Aztec" or the "Company") announces initial results from its 2024 surface exploration program that confirm the significant, broad, gold-silver mineralization found from 2020-2023 drilling in and around the Contention Pit at the Tombstone project which covers most of the historic Tombstone silver mining district in southeastern Arizona.


    • Initial Contention zone channel sampling results further demonstrate the presence of near-surface, broad, high-grade gold and silver mineralization confirming Aztec's drilling from 2020 to 2023.
    • Select channel line interval highlights include:
      • Line B4: 30.2 meters averaging 3.72 gpt Au and 167.93 gpt Ag (5.82 gpt AuEq using an 80:1 silver-gold ratio) including 6 meters of 13.15 gpt Au and 602.67 gpt Ag (20.68 gpt AuEq)
      • Line G1: 50.0 meters at 0.827 gpt Au and 54.08 gpt Ag (1.50 gpt AuEq)
      • Line C1: 42.3 meters at 0.46 gpt Au and 47.27 gpt Ag (1.05 gpt AuEq)
    • Preliminary results provide a roadmap for additional potential mineralization footprint expansion drilling on the western portion of the Contention Pit, aiming to discover new mineralized gold and silver zones. Additional continuous chip channel and reconnaissance sample assay results are pending.
    • This high-priority target area was historically reported as a target for open pit mining expansion by previous operators. (see Figure 1).
    • The mesothermal mineralization geological setting indicates a high potential for further discovery of wide oxide Gold & Silver along strike and down dip of prospective hosting rocks outcropping in the Contention Pit areas (see Figure 2)
    • Attractive, wide, gold and silver oxidized mineralization supports ongoing geological modelling targeting a potential bulk style of mineralization at the Contention Pit Area in the Tombstone Project

    The high-grade gold-silver sample results are located immediately adjacent to the Westside target area and indicate the strong potential to expand into multiple zones of broad Au-Ag oxide mineralization to the west.

    The initial results of the Channel Sampling Program, Lot 1, illustrated in Table 1, supports the presence of broad, mesothermal, gold and silver oxidized mineralization and suggests the potential for further expansion of the mineralization footprint in the host formations down dip and along strike, also demonstrating the potential extensions towards the west of the historical Contention Pit.

    2024 Exploration Program:

    Aztec collected and analyzed (482) rock chip channel and reconnaissance samples for multi-elements including 422 mine-cut chip channel samples of 2 meters length each from the Contention pit with accessible, visible coloration and/or alteration and 60 outcrop and waste rock storage site reconnaissance composite and select samples over the rest of the project, including the Westside area, to expand and enhance geochemical and geological knowledge throughout the Tombstone project exploration targeting. The first samples results of Lot 1 totaled 280 samples excluding the QAQC samples. Lines B1, B2, and E did not report > 0.1 gpt Au mineralized over their lengths in the Contention Pit area.

    Aztec's recent geological mapping at detailed scale (1:200) within the Contention pit and at reconnaissance scale (1:2,000) over the surrounding property has identified attractive mesothermal broad oxidized new mineralized zones. In the Contention pit mapping, recent detailed lithological, structural and alteration mapping is proving crucial for definition of the extensions towards the Westside area.

    Project data evaluation also continues to advance including the 3D modeling of the historic mine workings, drilling and geologic data. Modeling the geochemistry including trends of Au-Ag mineralization will then resume using the understandings gained on the multi-element relationships with Au-Ag, reviewing the subsequent results to the geophysical data and the SWIR-Terraspec data, and other investigations.

    The primary objectives of the 2024 surface exploration program are to continue to expand and define the shallow, open pit-table, oxidized gold/silver potential mineralization, and to also develop targeting for the CRD mineralization historically demonstrated to be present at depth.

    Tombstone Project Overview

    Aztec holds a 75% 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 2023 core drill program was to continue testing the shallow, bulk tonnage, heap leachable, mesothermal gold-silver oxide mineralization adjacent and below the previously mined Contention pit by infill and step-out drilling. Core drilling was needed in order to penetrate the multiple historic workings and to acquire critical geological data. Future drilling is expected to focus on strike and dip extensions of the shallow oxide mineralization, and move deeper to test for larger, deeper "Taylor-type" lead-zinc-silver CRD targets along and adjacent to the Contention structure.

    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.

    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.

    Although the historic silver mines at Tombstone were generally small, Aztec believes they could be related to much larger mesothermal and CRD orebodies 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 orebodies.

    Note: Gold equivalents are calculated using a 80:1 silver:gold ratio in 2020, 2023 and 2024, and a 70:1 silver:gold ratio in 2021.Reported lengths are apparent widths, not true widths. The Contention Au-Ag mineralization zones are generally west dipping at around 60-80 degrees, associated with the quartz-feldspar porphyry dikes. However, these dikes also extend as sills in shallow angles out from the Contention fault along fold noses in the Bisbee clastic sediments so the full range of mineralization dips vary from 20 to 80 degrees. True widths for the apparent mineralization intersection widths of the drill holes approximately range from 50 to 100% of the apparent widths, with the norm for the mineralized true widths being 60 to 90% of the apparent widths. Please see summary news releases dated: July 5, 2023, December 7, 2021, and January 12, 2021.

    Summary Tombstone Project Highlights
