Cervantes is a highly prospective porphyry gold-copper-molybdenum property located 160.0 km east of Hermosillo, Sonora, Mexico. It is well located within the Laramide porphyry belt approximately 265.0 km southeast of the huge Cananea porphyry copper-molybdenum mine of IMMSA and 55.0 km west of the Mulatos epithermal gold mine of Alamos. Our 3,650-hectare property is situated on private ranch lands accessed via dirt road from the town of Tonichi.

Aztec completed a Phase 1, 17 diamond core hole program in 2018, 2,675 meters in total. The drilling was conducted on 2 targets, the California and Jasper, however the bulk of work completed at California. Holes tested an impressive 900m by 600m gold in soils anomaly that averaged 0.44gpt over hydrothermal breccias, quartz feldspar porphyry intrusive, and Paleozoic siliciclastic sediments. Every hole in the Phase 1 drill program intersected porphyry-type gold-copper-silver mineralization, and most holes collared in outcropping mineralization.  Ignoring the abandoned holes CER1, 8 and 12, over half the holes at the California prospect intersected robust 100+ meter widths of higher-grade mineralization exceeding 0.4 gpt gold, spanning an 800-meter length and a 200-meter breadth, to a maximum vertical depth of 150 meters. The system is completely open in all directions.

The California gold-copper-silver mineralized target remains open for expansion along strike, across the breadth and down plunge, where a large, strong IP chargeability remains to be tested by future programs. Multiple gold+/-copper mineralized breccias and quartz feldspar porphyry host rocks exhibiting intense alteration continue to represent a dynamic and pervasive style of high-level porphyry mineralization for further drilling. Petrographic work on drill holes identified the presence of albite (sodic) alteration in addition to quartz-sericite-carbonate-chlorite-biotite-tourmaline hosted in breccias with igneous fragments of diorite to granodiorite. Sulphides identified include pyrite, chalcopyrite, covellite, cubanite, and sparse sphalerite.

Preliminary metallurgical studies on drill core samples were grouped into 4 separate types of mineralization (domains), Oxide 1, Oxide 2, Mixed Oxide/Sulfide and Sulfide. The following are very good results and show upside potential for heap leach gold recovery. Highlights of the bottle roll gold recovery results are 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

To date, 1,183 soil samples have been collected spanning about 630 hectares with sample spacings from 25m to 200m. Robust gold in soil anomalies are found on California, Purisima East, Purisima West, and Jacobo: only the California target has been drill-tested. Gold in soil anomaly measures 700m by 700m covering Purisima East and coincides with large breccia bodies resembling diatremes with strong sericite and kaolinite alteration.

A 12.8km pole-dipole IP geophysical survey was completed in 2016 over 220 hectares covering portions of the California soil anomaly and the Jasper prospect. Strong chargeability anomalies starting from the surface to depths of at least 600m were outlined with values ranging from 5 to 80mrads and averaging 40-50mrads. Such broad, strong chargeability anomalies are often associated with large zones of disseminated sulfide mineralization typical of porphyry copper deposits. A 3-dimensional IP survey covering 520 hectares was conducted in 2019, extending the coverage from the 2016 survey towards the west and southwest covering 3 additional targets: Estrella, Purisima East, and Purisima West. Impressive and extensive IP anomalies were detected from near surface to depths of 500m on all three targets. Collectively, Aztec has 740 hectares of IP coverage on the project with open-ended anomalies confirming the extensive mineral potential.

A helicopter airborne magnetic-radiometric-VLF survey was completed in 2018, covering the entire property with 100-meter spaced lines flown at 40m altitude. The data show multiple magnetic highs spaced along the northern 1/3rd of the property, often coinciding with the targets. A large magnetic high sits under the California target, extending north and east, supporting the association of gold-copper with a magmatic source. A slight embayment is noticeable at California where the gold+/-copper mineralization was detected in the 2018 drilling.

Aztec has completed an Option earn-in at the end of July 2019 with Kootenay Silver and acquired 65% of the project through USD$1,500,000 in expenditures, issuance of 1,000,000 Aztec shares, and payments amounting too USD$150,000. Aztec and Kootenay Silver will advance the project through a Joint Venture Agreement.
