Aztec Minerals (AZT.V) has released the assay results from an additional seven RC holes completed on its Tombstone gold-silver project in Arizona. Additionally, the company released the multi-acid digestion analytical results, providing more data compared to the fire assay results on holes 16, 17 and 17A that were released in November 2025. As you can see below, hole 17 intersected 57.8 meters of 5.16 g/t gold and 39.12 g/t silver for a total silver-equivalent grade of 400. This interval was boosted by a very high-grade zone where the drill bit intersected 4.6 meters of 58.5 g/t gold and 173 g/t silver for a total silver-equivalent grade of in excess of 4,200 g/t.
Hole 17 clearly yielded the best results in the batch of seven holes. And while all seven holes intersected gold and silver values, the exploration program is of course still geared towards figuring out the size of the mineralized area. Some intervals will meet the cutoff grade for a resource calculation and some won’t, that’s what exploration is. And it goes without saying that the current silver price of course is very helpful as even lower grade silver results could be economical (this of course will have to be confirmed in a maiden resource estimate for Tombstone and the subsequent economic studies).
Meanwhile, we are looking forward to seeing the results and data from the core holes. One deep hole (which reached the target depth of 694 meters) was completed on the northern end of the property, and assay results are still pending. The core rig is now working on another deep hole with TC25-04 designed to drill-test the AMT target under the Bisbee formation. The drill crew was hallway the hole when the Christmas break started so it will still take a while before assay results will be out.
