Aztec – Kootenay JV Continues to Intersect Broad, High-Grade Gold Mineralization in Phase 2 RC Drill Program at the Cervantes Project in Sonora, Mexico; Including 1.0 gpt Au over 167.2 metres
Vancouver, Canada – February 23, 2022 - Aztec Minerals Corp. (AZT: TSX-V, OTCQB: AZZTF) announces that it continues to intersect broad, high grade, gold mineralization in the 2022 RC drill program at the California target on the Cervantes property located in Sonora, Mexico. Results for hole CAL22-004 returned 167.2 metres grading 1.002 gpt Au including 24.4 metres grading 4.247 gpt Au.
The primary focus of the Phase 2 RC drill program at Cervantes is to expand the previously drilled California zone by completing two drill hole fences parallel to and on either side of the 2017-18 Phase 1 drill hole fence. To-date, every hole drilled at California has intersected near surface, oxidized gold mineralization with minor copper oxides.
California Zone Drill Highlights
- 1.002 gpt Au over 167.2 m in mineralized quartz feldspar porphyry, including 24.4 metres of 4.247 gpt Au in CAL22-004, located in the central part of the mineralized zone
- 0.374 gpt Au over 99.1 m in mineralized porphyries and hydrothermal breccias in CAL22-002 located at the west end of the mineralized zone
- 0.451 gpt Au over 45.7 m in mineralized porphyries in CAL22-003, including 13.7 metres of 0.868 gpt Au located at the south end of the mineralized zone

Reported lengths are apparent widths, not true widths, and the observed gold mineralization appears to be widely distributed in disseminations, fractures and veinlets within quartz-feldspar porphyry, feldspar porphyry stocks and related hydrothermal breccias.
Aztec CEO, Simon Dyakowski commented, “The 2022 RC drill program at the California zone, where we are targeting potential open pit heap leachable gold mineralization, continues to return strong gold grades over broad widths and has further expanded the gold mineralized zone to the west and south, still open in all directions including at depth.”
Holes CAL22-002 and 003 intersected extensive gold mineralization, see table below, extending the known mineralized zone at depth and to the north, west, and CAL22-004 to the south. The RC Phase 2 drilling program has been completed. It covers an area now measuring approximately 900 metres long by 250 to 500 metres wide, with demonstrated, continuous mineralization up to 265 metres depth vertically. The porphyry gold-copper mineralization is still open in all directions.

The Aztec-Kootenay JV has now completed its Phase 2 Reverse circulation (RC) program of 26 holes, totaling 4,649 metres at the Cervantes Property. Drilling commenced in December 2021. The first four RC drill holes were completed to test the previously undrilled Purisima East target, where high grade gold mineralization was sampled in a glory hole along the southern margin of a small felsic intrusion with coincident geochemical and geophysical anomalies. Preliminary gold assays in these four holes exhibit anomalous but sub-economic gold grades. The single drill holes at Jasper and California North found mineralized quartz feldspar porphyry with results pending.
The planned drill testing of the four main targets of the Cervantes phase 2 drilling program is complete. The primary objectives of the 2021 – 2022 phase 2 exploration program was to better define the open pit, heap leach gold potential of the porphyry oxide cap at California, evaluate the potential for deeper copper-gold porphyry sulfide mineralization underlying the oxide cap, test for north and west extensions of the California mineralization at California North and Jasper, and assess the breccia potential of Purisima East.
Drill samples cuttings are collected every 5 feet (1.52m) from all drill holes. The samples are analyzed by Bureau Veritas for gold with a 30-gram sample size using the method FA430 followed by MA300. 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. The samples are shipped to and received by Bureau Veritas Minerals laboratory for the gold and multielement geochemical analysis and additional gold results will be received and reported in the next several weeks. Final multielement ICP results are expected to follow the release of the preliminary gold assays and are expected to be received during the second quarter 2022.
Aztec will now carry out channel sampling and geologic mapping of the new drill roads at California, California Norte and Jasper, as well as to expand surface sampling and mapping on the property in general to continue the 2021 phase 1 surface program.
Cervantes Property Highlights
Cervantes is a highly prospective porphyry gold-copper property located in southeastern Sonora state, Mexico. The project lies 160 km east of Hermosillo, Sonora, Mexico within the prolific Laramide porphyry copper belt approximately 265 km southeast of the Cananea porphyry copper-molybdenum mine (Grupo Mexico). Cervantes also lies along an east-west trending gold belt 60 km west of the Mulatos epithermal gold mine (Alamos Gold), 35 km northeast of the Osisko Development San Antonio gold mine, 45 km west of the La India mine (Agnico Eagle), and 40 km northwest of Santana gold deposit (Minera Alamos).
