Aztec Minerals Corp. (TSX-V:AZT) (OTCQB: AZZTF) reports positive sample results up to 0.47 gpt gold over 222.0 meters on Line B from rock chip-channel sampling along drill roads at the California porphyry gold-copper prospect on the Cervantes property in Sonora, Mexico. 

Rock chip-channel sample results (see table below and map link here http://www.aztecminerals.com/_resources/AzMin-NR-Aug-22-2018-Link-1_California-Channel-Samples_Au_DDH_topo-(002).jpg) from five of seven sample lines confirm the previous highly anomalous soil sample results and the extensive porphyry-type gold mineralization intersected in the Phase 1 drill program.

Of particular interest is rock sample line G which returned 0.02 gpt gold over 111.0 meters adjacent to drill hole 18CER017 which intersected 0.35 gpt gold over 116.0 meters with 62.0 meters of 0.50 gpt gold. More studies are required to understand the controls on mineralization and infill drilling should help to better define the geometry of the subsurface mineralized zones.

Aztec’s CAD$182,000 Phase 2 exploration program of geological mapping, rock, soil and sediment sampling and airborne magnetic and radiometric surveys is focused on better defining additional drill targets on the recently expanded (3,649 hectares) Cervantes property.

New Terraspec SWIR analysis of core samples was recently conducted and results are under evaluation. Preliminary results suggest a good correlation between elevated gold values and high temperature muscovite and/or illite phyllosilicates. Recognizing the minerals associated with gold mineralization will assist Aztec in prospecting the rest of the Cervantes property. The Terraspec SWIR measures and identifies specific minerals including higher temperature, well-crystallized minerals often associated with gold mineralization.

To date, soil sampling results range from 0.005 gpt up to 3.30 gpt gold (mostly 0.05 to 1.0 gpt gold) and confirm four historic prospects as highly anomalous gold targets (see map link here http://www.aztecminerals.com/_resources/AzMin-NR-Aug-22-2018-Link-2_Cervantes-Gold-in-Soils_Property-Wide.jpg) at:

• California north extension soil assays up to 0.33 gpt gold, open to north and west
• Purisima East soil assays up to 3.3 gpt gold, 15 samples > 1.0 gpt gold, 700×700 meter anomaly
• Purisima West soil assays up to 0.61 gpt gold, open to east
• Jacobo soil assays up to 0.66 gpt gold, open in all directions

The previous IP-resistivity survey over the California prospect outlined a large, strong chargeability anomaly interpreted to be a zone of porphyry related sulfide mineralization extending from the interpreted base of the oxide zone around 100 metres deep plunging to the southeast down below the 400 metre depth limit of the survey. This chargeability anomaly remains a top priority drill target to expand the known porphyry type mineralization at the California prospect.

The airborne magnetic and radiometric survey is scheduled for completion in October after the rain season is over.  The airborne geophysical data should assist in identifying new prospective targets as well as refining our understanding of the multiple existing targets at Cervantes.  At that time, Aztec will evaluate its priorities for the next phase of drilling. 

The Cervantes Property is held under an option to purchase agreement with Kootenay Silver Inc. (TSX-V:KTN) whereby Aztec can acquire up to 100% interest in the property in two stages. Additional information can be found on our website.

Joey Wilkins, B.Sc., P.Geo., is the Qualified Person who reviewed and approved the technical disclosures in this news release. All rock samples were put into plastic bags, labeled with sample number, closed with zip ties, and placed in polyfiber sacks. Chip-channel samples were collected in 3.0 m intervals and described in detail. Blanks and certified standards were inserted into the chip-channel sample stream and subsequently reviewed, without any outliers or abnormal results. Soil samples were collected in the field with a minus 10 sieve, collecting 1.5 to 2.0 kg samples and placed in manila envelopes. The rock and soil samples were delivered to Bureau Veritas Laboratories in Hermosillo and analyzed for gold using a 30 gram sample by fire assay fusion with AAS finish. The XRF scanning for base and trace elements was conducted by a geologist in Hermosillo with an Innovex Delta, under Aztec supervision.
