Vancouver, Canada – November 21, 2024 – TheNewswire – Aztec Minerals Corp. (AZT: TSX-V, OTCQB: AZZTF) (“Aztec” or the “Company”) announces that the ongoing 2024 drilling program at the Tombstone Property in Southeastern Arizona has intersected broad gold-silver oxide mineralized zones in its first two step out RC drill holes in the Contention Open Pit target area.  Results for hole TR24-01 intersected 103.6 m at 0.75 gpt AuEq (0.59 gpt Au, and 12.48 gpt Ag); including 15.3 m at 3.11 gpt AuEq (2.84 gpt Au and 21.4 gpt Ag).  Hole TR24-02 intersected 0.19 gpt Au and 8.34 gpt Ag (0.30 gpt AuEq) over 149.4m.

 

The current Contention area step-out drilling program is targeting shallow zones, associated with recently completed surface exploration and 3D geological modelling, prospective for wide oxide gold-silver mineralization.  The 2024 RC drilling program has now completed 10 RC drill holes (see Figure 1 below), with results from the first 2 holes announced herein.  Visual observations of the drilled sample materials and initial assay results continue to validate Aztec’s geological exploration model.  As a result, the Tombstone Property JV Management Committee met last week and approved an expansion of the drill program from an initially planned 12-hole, 2,000-meter program, to 3,000 meters over 18-20 drill holes.

 

Initial Drilling Highlights:

 

• Hole TR24-01 - 0.59 gpt Au 12.48 gpt Ag (0.75 gpt AuEq) over 103.6m, including 15.3m grading 2.84 gpt Au 21.4 gpt Ag (3.11 gpt AuEq), and 3.05m grading 10.63 gpt Au 35.10 gpt Ag (11.06 gpt AuEq). The hole was oriented azimuth 105, -60, and was designed to test for westerly and down dip extensions of mineralization under the west pit wall and to depth.  The interval is composed of siliciously and argillically altered, lower Bisbee group fine-grained sandstones/quartzites, siltstones/hornfels cut by quartz-feldspar porphyry dikes, hydrothermal breccias and faults/fissures with quartz veining.  Moderate to strong iron oxides, manganese oxides, orange to red color, and 1 to 10% oxidized pyrite sites. The drill hole had to be abandoned due to caving. 

 

• Hole TR24-02 - 0.19 gpt Au 8.34 gpt Ag (0.3 gpt AuEq) over 149.4m, ending in low grade mineralization and including 7.6m grading 1.65 gpt Au 12.16 gpt Ag (1.8 gpt AuEq). The hole was oriented azimuth 105, -60, and was designed to test for westerly and down dip extensions of mineralization under the west pit wall and to depth. The interval is composed of siliciously and argillically altered, lower Bisbee group fine-grained sandstones/quartzites, siltstones/hornfels cut by quartz-feldspar porphyry dikes, hydrothermal breccias and faults/fissures with quartz veining.  Moderate to strong iron oxides, manganese oxides, orange to red color, and 1 to 5% oxidized pyrite sites.

The primary objectives of the drilling program are to: Expand the known mineralization horizontally to the west and down dip beyond the holes drilled by Aztec in 2020-23 at the Contention Pit with step outs to enlarge the shallow, broad, bulk tonnage gold-silver mineralization discovered there; and also to explore with first pass drilling new targets identified in the Westside area.

 

The initial seven RC holes were drilled as part of a “fan grid pattern” being drilled in the Contention area since 2020.  The RC drill holes are to test for extensions on the western and eastern borders and also underneath of the north-trending main Contention target zone which hosts the historic underground and open pit Contention mine.  The drill program continues to identify 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 continue to be outlined by the current drilling, including manganese replacements in limestone beds and skarns, quartz veinlets, sulfide relicts as disseminations, silicification of altered hornfels, quartz feldspar porphyries and hydrothermal breccias.  To date, TR24-07 is the deepest hole drilled, has an inclination of -60 degrees and was drilled to a depth of 256.1 m (221.7 m vertical) remaining in mineralized and oxidized rocks the majority of its length.

 

The initial drilling results show that the Contention area mineralization is still open to the west and to depth and the mineralized volume is expanding.

Aztec holds a 77.7% interest in the Tombstone property, which includes the majority of the original main mining district.  The main target of the current RC drill program is to test for shallow, bulk tonnage, heap leachable, mesothermal gold-silver oxide mineralization adjacent and below the previously mined Contention pit.  The current drilling program will continue the testing of the Contention target zone and then complete Aztec’s first drilling in the Westside target zone which is comprised of several demonstrated mineralization focusing structures – anticlines, quartz stringer fissure lodes, and quartz feldspar porphyry dikes.

 

Future drilling is expected to focus on extensions of the shallow oxide mineralization already tested, as well as larger, deeper “Taylor-type” CRD targets along and adjacent to the Contention structures.

Tombstone Project Overview

 

Aztec holds a 77.7% 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 2024 drill program 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 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 gold1.

 

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 Tombstone2.

 

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.

 

Note 1: 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 and hydrothermal breccias.  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.
