Aztec Completes Initial 7 Holes Expanding the Gold Mineralization Footprint at the Cervantes Project, Sonora, Mexico

VANCOUVER, BC / ACCESSWIRE / November 21, 2023 / Aztec Minerals Corp. (TSXV:AZT)(OTCQB:AZZTF) announces that the first 7 holes totaling 963.2 meters (m) of the proposed 1,650m, 11-hole reverse circulation "RC" drilling program have been completed at its 100% owned Cervantes project in Sonora, Mexico. RC chip logging of the 7 holes indicate favorable geology to support potential expansion of the gold zone mineralization in the vicinities of the area previously drilled (Figure 1.). The initial 7 holes were drilled on the primary California gold zone target with step out drilling focused on expanding the zone to the north, west and south of previous drilling where Aztec had discovered extensive shallow, wide oxide gold mineralization (previously drilled intercepts of up to 1.5gpt gold over 137m and 1.0 gpt gold over 165m). Drill samples have been shipped to the Bureau Veritas Minerals Laboratory for geochemical analysis and initial results are expect in the next several weeks.

The visual logging of the RC chip samples from the initial 7 holes continues to show evidence of wide zones of strongly altered rocks with porphyry style A, B, and C veinlets, similar to previously drilled zones at the Cervantes Project.

The gold mineralization is characterized by oxidized and unoxidized stockwork veinlets of A, B, and C types and disseminated sulfide sites, with silicification and phyllic alterations. Potassic alteration is present in places and is associated with mineralization as well. The company continues exploration on the potential step-out areas (Green Zone - Figure 1), to support future delineation of new drilling targets in the vicinities of the drilled area, aiming to define a much larger, potentially amenable to heap leaching, gold mineralized zone.

The seven holes were drilled in a general "grid pattern" used at the California target with general orientations of azimuth 250, inclined at 60-65 degrees as "step outs" to expand the California target. The California porphyry gold-copper mineralization is at, what is interpreted to be, the top of the porphyry system with diagnostic UST (unidirectional solidification textures) and abundant breeched blocks of metasediments in the intrusives. The mineralization is primarily hosted in two lithologic units, quartz-feldspar porphyry (Qfp) and hydrothermal breccias (Hbx) associated with it. There are also less favorable host rocks present including feldspar porphyry (Fp), metasediments (quartzites and hornfels - Ms), and mafic dikes (Md).
