- Assay results of 4-hole North Spoke Pattern (holes 6-9) reported herein
- Holes 6-9 drilled ~300 meters north of previously released 4-hole Central Spoke Pattern (holes 2-5) along the Contention open pit
- Hole TR20-09 reported highest-grade drill result to date
- 20-hole Phase 1 drill program continues with results pending from 4-hole South Spoke Pattern at south end of Contention Pit
VANCOUVER, BC / ACCESSWIRE / October 21, 2020 / Aztec Minerals Corp. (TSXV:AZT)(OTCQB:AZZTF) announces it has received the assay results for drill holes TR20-06 to 09 at the north end of the Contention open pit as part of the ongoing Phase 1 reverse circulation (RC) program at the Tombstone project in southeastern Arizona.
Highlights include drill hole TR20-09 which returned 6.18 grams per tonne (gpt) gold and 77.2 gpt silver (7.15 gpt gold equivalent (AuEq) using an 80:1 silver:gold ratio) over 15.14 meters (m) within 30.48m of 3.21 gpt gold and 45.6 gpt silver, starting from 32.00 meters depth. Reported lengths are apparent widths, not true widths, which range from 30% to 55% of apparent widths.
The four-hole North spoke pattern was drilled approximately 300 meters north of the four-hole Central spoke pattern (assay results previously released on September 29, 2020) along the Contention open pit. The North spoke pattern results are highlighted by hole TR20-09 which returned the highest grade drill intersection to date on the Tombstone project.

"Aztec's first ever drill program at the Tombstone project continues to deliver encouraging results. This second batch of assays includes significant intersections of both shallow, bulk tonnage, open pit-type gold and silver mineralization as well as deeper, high grade, underground-type mineralization at the north end of the Contention Open Pit", stated CEO Simon Dyakowski.
All four holes in the North Spoke Pattern intersected old mine workings, likely dating back to the late 1800's, indicating that the highest-grade bonanza mineralization in the area drilled was previously mined out. High grade gold and silver, however, was drilled peripheral to the tunnels, including 1.52m grading 20.9 gpt gold, 12.8 gpt gold, and 283 gpt silver.
High grade intervals were also intersected in other drill holes such as hole TR20-06 which intersected 3.65 gpt gold and 48.5 gpt silver (4.26 gpt AuEq) over 4.57m beneath an old mine working. Bulk tonnage intervals were intersected in several holes including hole TR20-08 which encountered 57.91m of 0.59 gpt gold and 11.8 gpt silver (0.74 gpt AuEq) starting at 12.19m depth, once again indicating shallow, bulk tonnage, open pit potential.
The North spoke pattern measures 125 meters north-south along strike by 75 meters east-west perpendicular to the Contention mineralized structure, with gold-silver mineralization still open in all directions, particularly to the south. The South spoke pattern (holes 10-13) currently being drilled is located 350 meters south of Central spoke pattern.
Holes TR20-10 to 13 have intersected widespread jasperoid alteration and oxide mineralization spanning an area 130 m long by 60 m wide. The alteration transitions at shallow depths from goethite to hematite rich vuggy quartz and manganese wad plus calcite altered sediments. Results for these next four holes are pending.
Drilling continues to encounter hydrothermal breccias, abundant quartz veining and silicification associated with gold and silver mineralization, moderate to strong alteration, quartz feldspar porphyry dikes, and strongly altered host sandstone and siltstone throughout. Intense hematite and goethite are frequently encountered peripheral to the porphyry dykes and manganese wad-quartz-calcite replacement and skarn alteration are found in limestone interbeds. Cerargyrite (silver chloride) and fine-grained visible gold are frequently found in the porphyry dykes and surrounding hydrothermal breccias. Most silver and gold mineralization are proximal to the old underground mine workings, both in hangingwall and footwall rocks.
Drill results for the North Spoke Pattern are as follows:

Aztec holds an option to acquire a 75% interest in the Tombstone property, which includes most of the original patented mining claims in the district as well as some recently acquired properties. The main target of the current RC drill program is to test for shallow, bulk tonnage, heap leachable, epithermal gold-silver oxide mineralization adjacent and below the previously mined Contention pit.
QA/QC Protocol
Joey Wilkins, B.Sc., P.Geo., VP Exploration & Chief Geologist for Aztec, 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. All samples are shipped to Bureau Veritas Minerals laboratory in Hermosillo, Mexico and Vancouver, BC, Canada for geochemical analysis. The QA/QC has delivered excellent results to date good data integrity. Mr. Wilkins reviewed and approved the technical disclosures in this news release.
