Aztec Receives Initial 2021 RC Drill Results from Tombstone Project, Arizona
Intersects Broad and High-Grade Gold-Silver Mineralized Zones / Including 5.71 gpt Gold and 40.5 gpt Silver (6.282 gpt AuEq) over 32.01 m

5 holes drilled along the north-central Contention pit confirm and expand the near surface, oxidized gold-silver mineralization
20 hole program continues to target gold and silver mineralization at north and central portions of the Contention Pit
Aztec Minerals Corp. (AZT: TSX-V, OTCQB: AZZTF - https://www.commodity-tv.com/ondemand/companies/profil/aztec-minerals-corp/) announces it has received the assay results from the first five holes of its 2021, Phase 2, 20 hole, 2,900 meter reverse circulation (RC) drill program on the Tombstone project at the historic Tombstone silver mining district in southeastern Arizona.
The first five holes were drilled in two fan patterns below the north-central part of the Contention open pit, stepping out from and filling in between the 2020 north and central Contention drill patterns.
Drill Highlights
713 grams per tonne (gpt) gold and 40.5 gpt silver (6.282 gpt gold equivalent (AuEq)) over 32.01 meters (m), including 15.24 m grading 11.891 gpt gold and 62.9 gpt silver (12.79 gpt gold equivalent AuEq) in hole TR21-03
19 gpt gold and 37.1 gpt silver (1.72 gpt AuEq) over 21.34 m in hole TR21-04
07 gpt gold and 26.1 gpt silver (2.44 gpt AuEq) over 21.40 m hole TR21-05
Gold Equivalents are calculated using a 70:1 silver:gold ratio. Reported lengths are apparent widths, not true widths.

All 5 holes intersected extensive gold and silver mineralization, see table below, extending the mineralized zones at depth and along strike, below and west of the Contention open pit. Two of the five holes also intersected old mine workings, likely dating back to the late 1800?s, indicating that the highest-grade bonanza mineralization in the area drilled was mostly, previously mined out.
The area drilled on the west side of the Contention Pit is adjacent on the north to the area drilled in 2020 near the centre of the pit (central drill pattern). The area drilled measures 145 meters north to south along strike by 65 meters east-west perpendicular to the Contention mineralized structure, with gold-silver mineralization still open in all directions. The drilled area reported herein demonstrates mineralization over a combined length of 290 meters from the 2020 and current drilling. Holes TR21-06 to 11 have been completed and sampled and each hole intersected similar widespread alteration and mineralization spanning an area 350 m long by 65 m wide.
Aztec CEO, Simon Dyakowski commented, ?Our initial 2021 drill program results have exceeded our expectations, returning strong grades over broad widths and confirming and expanding the historic gold and silver mineralized zones. Holes 21-6 to 10 also intersected strong and broad mineralized zones, and continue to show strong geological similarities to both the initial drill holes and the historic drill holes.?
Tombstone 2021 RC Drill Program Plan Map
The low sulfidation epithermal gold-silver mineralization observed to date is impressive, marked by hydrothermal breccias, quartz veining and silicification associated with quartz-feldspar porphyry dikes and moderate to strong potassic, argillic and advanced argillic alteration within the host Bisbee sandstones and siltstones. Areas of intense hematite, goethite and manganese wad are extensive, associated with quartz-calcite veins and localized skarn alteration in limestone. Cerargyrite (silver chloride) is observed in fractures, often with fine-grained visible gold. Most silver and gold mineralized zones intersected in the 2020 and 2021 drill programs are proximal to and in the hanging-walls and footwalls of old underground mine workings.
Aztec is currently over half-way through the planned 2,900 metre, 20-hole Phase 2 reverse circulation (RC) drilling program at the Tombstone Property.
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 district as well as some recently acquired properties. The main target of the 2021 Phase 1 RC drill program is to continue testing the shallow, bulk tonnage, heap leachable, epithermal gold-silver oxide mineralization adjacent and below the previously mined Contention pit by infill and step-out drilling.
Allen David Heyl, B.Sc., CPG., VP Exploration, is the Qualified Person overseeing the Tombstone exploration program. Drill cuttings are collected every 5 feet (1.52m) from all drill holes. The samples were analyzed for gold with a 50-gram sample size using the method FA450 followed by AQ200. Over limits, when present, are analyzed by AR404 or FA550. All holes contain certified blanks, standards, and duplicates as part of the quality control program. The QA/QC has delivered excellent results to date good data integrity. Mr. Heyl reviewed and approved the technical disclosures in this news release.
