Widespread Visible Copper Mineralization With Quartz Feldspar Porphyry Intrusion in RC Drill Hole at Jasper Target 600 m West of California Zone at Cervantes
- Initial gold results for Hole CAL22-017, a 350 metre step-out from California zone to California North target, returned 24.3 metres @ 0.32 gpT Au and 6.1 metres @ 1.65 gpT Au with quartz feldspar porphyry intrusion
- Widespread visible copper mineralization with quartz feldspar porphyry intrusion in RC drill hole JAS22-001 at Jasper Target 600 m west of California Zone, including 9.1 metres @ 0.332 gpT Au
- Continued intercepts of broad gold mineralization in the California zone
- First Multi-Element ICP results received for California drill holes
- Initial gold results from 5 additional drill holes still pending
Vancouver, Canada – May 5, 2022 – Aztec Minerals Corp. (AZT: TSX-V, OTCQB: AZZTF) announces that recent drilling has intersected gold mineralization in a 350 metre step-out north of the California zone at the southern edge of the California North Target, returning 24.3 metres grading 0.315 gpT Au and 6.1 metres grading 1.649 gpT Au with quartz feldspar porphyry intrusion.
At the Jasper target, widespread visible copper oxides and secondary sulfides were observed with a quartz feldspar porphyry intrusion some 600 m west of the California Zone, including gold mineralization grading 0.332 gpT Au over 9.1 metres.
Additional drill results at the California target continue to return broad gold mineralization from the 2022 RC drill program on the Cervantes property located in Sonora, Mexico. Results for hole CAL22-015 returned 68.4 metres grading 0.421 gpT Au and CAL22-016 returned 56.2 metres grading 0.475 gpT Au. The first multi-element ICP results show good relationships between Au, Cu, Bi, Ag and As, with prospective grades and widths for Cu and Ag for a potential porphyry deposit model.
California and Jasper Zone Drill Highlights
- 9.1 metres of 0.332 gpT Au and 150 metres with visible Copper oxides and secondary sulfides in mineralized quartz feldspar porphyry intrusive, sediments and hydrothermal breccias in JAS22- 001, as a 180 m step-out in the Jasper target to the southwest of the 2018 drilling.
- 24.3 metres of 0.315 gpT Au and 6.1 metres of 1.649 gpT Au in mineralized quartz feldspar porphyry, sediments and hydrothermal breccias in CAL22-017, as a 350 m step-out north onto the southern edge of the California North target.
- 0.421 gpT Au over 68.4 m in mineralized porphyries and hydrothermal breccias in CAL22-015 located at the southern edge of the eastern portion of the mineralized zone
- 0.475 gpT Au over 56.2 m in mineralized porphyries and hydrothermal breccias in CAL22-016, located at the northern edge of the eastern portion of the mineralized zone
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.
View drill section here:
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.
Holes CAL22-015, 016 and 017 intersected broad gold mineralization, see table below, extending the known mineralized zone at depth and over 350 metres to the north onto the California North target confirming it as a target of immediate interest, and also to the south on the eastern end of the California zone. 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 first multi-element ICP results show good relationships between Au, Cu, Bi, Ag and As, which will assist in vectoring exploration targets for potentially economic grades and widths for Cu and Ag in a porphyry deposit model. The multi-element ICP values support the exploration model of the California zone being at the highest portion of a porphyry system, where an overlying high sulfidation zone has been eroded away.

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 planned drill testing of the four main targets of the Cervantes phase 2 drilling program is now 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 review for all drilling has been completed with excellent results showing 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 has recently completed drill hole collar surveying, field work for Drone Photogrammetry survey created a detailed ortho-topographic base map, and Terraspec readings on the RC drill chips. Aztec is now carrying out channel sampling and geologic mapping of the new drill roads at California, California Norte and Jasper, relogged the 2017-2018 core, expand surface sampling and mapping on the property in general to continue the 2021 phase 1 surface program, and generate Leapfrog modeling of the geology, geochemistry and geophysics.
