Massive Gold Bar Unearthed in Mexico Was Looted Aztec Treasure

reports a summary of the recently completed 2023, 7-hole, core drill program on the Tombstone project which covers most of the historic Tombstone silver mining district in southeastern Arizona. Every one of the drill holes intersected near surface, oxidized gold-silver mineralization, and all the drill holes crossed multiple historic underground workings where presumably most of the highest-grade ores were previously mined, and all drill holes bottomed in alteration and mineralization, indicating the main mineralized zones are still open to depth and laterally.

The drill holes were drilled on an azimuth 103 fence pattern cutting across the NNE trending Contention target zone mineralization with approximately 50 m spacings, with inclined fans varying from near vertical to the east at -60 degrees. The 2023 drill holes are step outs of 40 to 150 metres from the 2020-21 program, in various portions of the Contention pit target zone.

Top caps of 1 gpt Au and 100 gpt Ag are used when needed. Over limits, when present, are analyzed by MA370 or FA530.

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.

Table 2: Completed Drillhole Details (WGS84, Zone 12R)Aztec has now completed the seven hole core drilling program. 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 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 deemed needed in order to penetrate the multiple historic workings and to acquire needed 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" 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-lead-zinc-copper mesothermal and CRD mineralization hosted in veins, mantos, pipes and disseminated orebodies that were mined in the late 1800's and early 1900's. Host rocks to the mineralization were primarily the clastic sediments of the Cretaceous Bisbee Formation.

Below 200 meters (m) in depth, the Bisbee is underlain by the same Paleozoic limestone formations that host the Taylor zinc-lead-silver deposit located 60 km southwest of Tombstone. Taylor was discovered by Arizona Mining in 2015 and they accepted a takeover bid from South32 Limited in 2018. 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.

The 2020-21 drill holes were collared along the western rim and inside of the north and central parts of the Contention Pit and intersected mineralization over a north-south length of 600 meters by over 150 m of east-west width and to maximum depths of 175 m.
