Aztec Minerals Hits Impressive 167.2m @ 1.0g/t Oxide Gold From Surface At Cervantes





 

After completing the first 26 holes of their Phase 2 RC drill program at the California target, part of their Cervantes gold-copper project in Sonora, Mexico on January 26, 2022, Aztec Minerals Corp. (AZT: TSX-V, OTCQB: AZZTF) doesn�t seem to suffer a lot from the common and extensive lab delays, and continues to release excellent drill results after the first hole was returned just over a week ago. Back then the result was a 88.4m @ 1.1g/t Au intercept, and more recently they announced an even more impressive 167.2m @ 1.0g/t Au, as part of a batch of 3 holes.

These results are already very good for a standard open pit deposit, but in this case Aztec is drilling out potentially heap leachable mineralization as it is targeting the oxide cap of a potential porphyry, and heap leach operations have far better economics. A follow -up drill program is anticipated in a few months. As a reminder, the Cervantes oxides aren�t the only thing Aztec is looking to explore, as it is also planning a drill program for their Tombstone gold-silver oxide project in Arizona for the summer, also enabling them to go after large porphyry/CRD potential at depth at both projects.

The releasing of strong drill results didn�t go unnoticed for investors, as there was significant volume right after the two most recent news releases, resulting in a healthy recovery: PDF attached

And these are only the first 4 drill results, with many more to come. When all assays are announced, I expect the markets to have more awareness about Aztec for sure. The cash position is estimated at C$1M at the moment, meaning that further financing will be needed for follow up drilling (being either a financing or warrant exercise), depending on drill results and general sentiment. For now, let�s have a closer look at the current drill results coming out of the California target.

The California target is located on a ridge, and is only a small part of the Cervantes project. 17 holes have been drilled in 2017-2018, with lots of economic intercepts, causing me to guesstimate resource potential on these holes alone at about 600koz Au. These earlier holes, and the recently drilled ones can be seen here on this map: PDF attached

As can be seen, most holes are step-outs to the north, parallel to the earlier drilled holes. The red holes are the ones reported in the last news release, holes 002, 003 and 004. Hole 001 was reported a week before this, and is located directly east of 002.

The following table shows the complete results: PDF attached

These results are very impressive, especially considering the grade, which is often much higher than the 2017-2018 holes nearby. For example, close to standout hole 004 we can find hole 18CER006, which intercepted 170m @ 0.42g/t Au. Another remarkable example is hole 001 which is located close to 18CER014, returning 98.5m @ 0.41g/t Au, which is considerably less than 61m @ 1.45g/t Au. Management doesnâ€?t have an explanation for this, but it certainly is intriguing, and these holes alone have the potential to add another 100koz Au to my guesstimate. 

Keep in mind true width is often smaller, as most holes have been drilled under an angle following the slopes of the ridges, as can be seen for this section of hole 003 for example: PDF attached

If the remaining assays could emulate the 2017-2018 results, or even improve on them like the recent ones did, there is not too much doubt in my mind Aztec could be closing in on a 1Moz Au mineralized envelope. A good thing is that, so far, most of the intersected mineralization is oxidized according to the geologists, with only the bottom end representing transitional ore. As recoveries for this type of ore are also good for this project (bottle roll heap leach test gold recoveries 77.9%), management doesn�t mind too much.

Besides going after more oxides, let�s not forget Aztec is also hunting large porphyry targets at depth at Cervantes. Deeper tests have been completed at California target as part of this drill program to test the large IP chargeability anomaly at depth. The balance of the Phase 2 program tested an gold-in-soil anomaly at California Norte, and an outcrop at the Jasper target. The remaining results are expected in the coming weeks.

The first 4 holes of the 26 hole program were actually drilled at the Purisima East target, which had never seen drilling before. Unfortunately these holes didn�t return any economic mineralization. According to CEO Dyakowski this target will be reviewed to better understand the target before it sees any additional drill testing.

The program was designed 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. Although not all results are in, based on handheld inspection of cores, management believes it might have done well on most goals except Purisima East.

Aztec will now 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, in order to continue the 2021 phase 1 surface program. After this, all exploration results will likely be released, it will be most likely time to do another raise, and, contingent on the current program results, and available funds, management could plan additional drilling this spring season .

As Aztec isn�t just advancing Cervantes, but is also advancing their Tombstone project in Arizona, I asked CEO Dyakowski what to expect here.

He answered that they have a diamond drill program planned for the summer of this year, contingent on available funds. This upcoming Phase 3 drill program will be designed to target deeper epithermal gold-silver mineralization below the Contention pit, and the coveted deep CRD silver-lead-zinc-copper-gold mineralization in Paleozoic limestones underlying the Bisbee Sediments.

Conclusion

The first drill results at the California target were pretty impressive, with hole 004 as absolute highlight, intercepting 167.2m @ 1.0g/t Au from surface. Considering this is almost all oxides, as Aztec is looking to delineate a heap leach deposit, this is an excellent intercept all around. For heap leaching a grade of 0.30-0.40g/t Au would already be economic, so the actually drilled grade over such a distance with no overburden is nothing short of sensational. Of course not all drill results were as good and I would be surprised as many of the upcoming ones would come close with these kind of numbers as well, but it certainly looks like Aztec has a very decent shot at delineating at least 1Moz Au at California. In my view, the same potential is present at their Tombstone project in Arizona, and both projects have geophysics completed on them, indicating large, deep targets for both, so in fact investors might be looking at 4 potential company makers. Still early days, but Aztec already has a good look on 2 of them. Stay tuned.
