Drill Results Extend the Broad California Zone Mineralization to the North with Step Out Drilling

• Initial Results received from an additional 5 core drill holes
• Step out drilling expands California Zone to the North with continued broad intercepts of gold mineralization
• Step out drilling also expanded the footprint of the California mineralized Qfp intrusive complex to depth and to the Southwest
• Initial gold results from 3 additional drill holes are pending

VANCOUVER, BC / ACCESSWIRE / November 15, 2022 / Aztec Minerals Corp. (AZT:TSX-V, OTCQB:AZZTF) announces that it continues to intersect gold mineralization extending the California Zone to the North with initial assay results for five additional core holes from the recently completed the Phase 3 core drilling program at the Cervantes Project in Sonora, Mexico. The results also extend the California mineralized and altered Qfp intrusive complex to depth, toward the Southeast and Northerly directions. Results for hole CAL22-029, a step out extending the California zone to the North, returned 57.0 m grading 0.77 gpT Au.

Results for drill hole CAL22-027 in the West-Central area of the California Zone returned 120.0 m grading 0.68 gpT Au. This drill hole confirms the California Zone mineralization in a gap and may be used for metallurgical testing. Drilling has also expanded the footprint of the known extents of the mineralized and altered California Qfp intrusive complex to 400 m depth and 450 m to the Southeast and 60 m to the North. Surface exposures of altered Quartz-feldspar porphyry intrusive (Qfp), the principal host for the California target's gold mineralization, that had been covered by colluvium have been found in the new drill road cut exposures for the 450 meter step-out between these recent core drill holes on the Southeast side.

To-date, every hole except one, drilled at the California Zone target has intersected near surface, oxidized gold mineralization with minor copper values.

California Zone Drill Highlights

• CAL22-027 - 120.0 m @ 0.68 gpT Au
• CAL22-029 - 57.0 m @ 0.77 gpT Au

The primary focus of the Phase 3 Core drilling program at Cervantes is to expand the previously drilled California target, California North and Jasper targets, to enhance geologic understanding of the targets, and to collect a sample for metallurgical testing. The oriented core drilling program in 2022 tested step-outs of 35 to 450 meters using varying azimuths and inclinations. The Phase 3 Core drilling program at Cervantes was comprised of eleven core holes totaling 2,515.5 meters drilled at the California, California North and Jasper targets. The program was conducted in the rainy season with no injuries or accidents.

Reported lengths are apparent widths, not true widths, and the gold mineralization appears to be widely distributed in disseminations, fractures and veinlets at high levels within in a Quartz-feldspar porphyry intrusive complex and related hydrothermal breccias.

California 2022 Core Drill Program Plan Map

Holes CAL22-025 to 029 intersected extensive gold related mineralization and alteration, see table below, extending the known mineralized zone at depth, to the north, and to the southeast. The area currently being drilled measures approximately 900 meters long E - W by 730 meters wide, with demonstrated, continuous mineralization of up to 170 meters in depth. The porphyry gold-copper mineralization is still open in all directions.

The planned testing of three main targets of the Cervantes Phase 3 core drilling program is complete. The primary objectives of the 2021 - 2022 exploration program are to better define the open pit, heap leach gold potential of the porphyry oxide cap at California, evaluate the potential for deeper gold - copper porphyry sulfide mineralization underlying the oxide cap, test for north and west extensions of the California mineralization at California North and Jasper, and collect samples for metallurgical testing.

Drill samples cuttings mainly are collected every 1.5m from all core 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 third and fourth quarter 2022.

After drilling concludes, Aztec will 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 - 2022 surface exploration program.

California Target

In 2017-18, Aztec completed a Phase 1, 17 diamond core hole drill program, totaling 2,675 meters (m) (see news release dated June 26, 2018). Phase 1 drilling tested the California target 900m by 600m gold-in-soils anomaly that averaged 0.44gpt covering hydrothermal breccias within a Quartz feldspar porphyry stock intruding Paleozoic siliciclastic sediments.

In early 2022, Aztec completed a Phase 2, 26-hole, RC (reverse circulation) drill program totaling 5,267 m focused on expanding the California zone with two drill hole fences parallel to and on either side of the 2017-18 Phase 1 drill hole fence. The Phase 2 RC drilling program successfully expanded the primary California zone to area now measuring approximately 900 meters long by 250 to 500 meters wide, with demonstrated, continuous anomalous mineralization up to 265 meters depth vertically.

The porphyry gold-copper mineralization is still open in all directions. Aztec's drilling to-date has consistently intersected an oxidized gold cap to a porphyry-type gold-copper-silver system at California, including multiple 100+ meter widths of exceeding 0.40 gpt gold.

Highlights of the 2017-18 Phase 1 diamond core and 2021-22 Phase 2 RC (see news release dated June 14, 2022) drill programs are as follows:

• 137m @ 1.49 gpT Au incl 51.7m @ 3.42 gpT Au, 119m @ 0.091% copper in CAL22-005
• 165m @ 1.00 gpT Au incl 24.4m @ 4.25 gpT Au, 160m @ 0.065% copper in CAL22-004
• 152m @ 0.87 gpT Au, incl 33.5m @ 2.05 gpT Au, 123m @ 0.095% copper in CAL22-012
• 94m @ 1.04 gpT Au incl 15.2m @ 3.96 gpT Au, 55m @ 0.36% copper in CAL22-001
• 100m @ 0.75 gpT Au incl 9.14m @ 3.087 gpT Au, 138m @ 0.10% copper in CAL22-006

• 139m @ 0.71 gpT gold incl 20m @ 2.10 gpT gold, 0.16% copper in 17CER005
• 118m @ 0.63 gpT gold incl 43m @ 1.18 gpT gold, 0.16% copper in 17CER003
• 122m @ 0.60 gpT gold incl 62m @ 0.88 gpT gold, 0.06% copper in 18CER007
• 170m @ 0.42 gpT gold incl 32m @ 0.87 gpT gold, 0.06% copper in 18CER006

Preliminary metallurgical tests on California drill cores were conducted in 2019 (see news release dated March 12, 2019). Drill core samples were grouped into 4 separate types of mineralization: Oxide 1, Oxide 2, Mixed Oxide/Sulfide and Sulfide. The preliminary results of bottle roll tests showed excellent potential for heap leach gold recovery, as follows:

• 85.1% recovery on 2.0mm material and 94.3% on 75-micron material in sample Oxide 1
• 87.7% recovery on 2.0mm material and 94.2% on 75-micron material in sample Oxide 2
• 77.9% recovery on 2.0mm material and 89.0% on 75-micron material in sample Mixed Oxide/Sulphide
• 51.2% recovery on 2.0mm material and 78.7% on 75-micron material in sample Sulphide

Additional Targets

Purisima East - outcropping gossans, altered and mineralized diatreme breccias and porphyry intrusions marked by a 700m by 600m geochemical soil anomaly in 193 samples that average 0.25 gpt gold, a small historic ‘glory hole' mine where rock chip sampling returned high-grade mineralization up to 44.6 gpt gold.

Estrella - outcrops of gossan and sulfides in silicified Paleozoic sediments near quartz porphyry dikes with rock chip samples up to 3.9 gpt gold and 2,010ppm copper.

Purisima West - a mirror image of Purisima East in size and type of gossans, altered and mineralized breccias and intrusions in association with gold and copper soil anomalies.

Jasper - 2017 trenching returned skarn/replacement-type mineralization up to 0.52% copper and 0.62 gpt gold over a 92.4 m length. In 2022 RC drilling found a broad zone of copper - gold mineralization in JAS22-001.

California North - coincident IP chargeability and gold-copper-molybdenum soil geochemical anomalies with demonstrated gold - copper mineralization by RC drilling, it may be a north extension of the California target

Other targets - porphyry alteration and geochemical soil anomalies mark the Jacobo and Brasil prospects but more work is required to expand and define these targets
