Aztec Expands Drilling Program at the Tombstone Project, Arizona

Core Insights - Aztec Minerals Corp. has provided an update on its ongoing drilling program at the Tombstone Property in Southeastern Arizona, having completed 34 reverse circulation (RC) drill holes and 13 reported drill holes, totaling 5,960 meters of RC drilling and 495 meters of core drilling to date [1][2][5] - The drilling program has been expanded from 7,500 meters to at least 8,500 meters, with plans for 7,000 meters of RC drilling and a minimum of 1,500 meters of core drilling, expected to extend into Q1 2026 [2][5] - The company anticipates improved turnaround times for geochemical analysis due to recent staffing additions and equipment repairs at the Bureau Veritas laboratory, with additional results expected within 30 days [3] Drilling Program Details - The core drilling portion has resumed, currently advancing to a total depth of 465 meters in drillhole TC25-03, with plans to further test previously identified targets beneath the Bisbee formation [4] - The main target of the drilling is to assess shallow, bulk tonnage, potentially heap leachable, mesothermal gold-silver oxide mineralization adjacent to the previously mined Contention pit [9] - The Tombstone project is located 100 kilometers southeast of Tucson, Arizona, covering much of the historic Tombstone silver district, known for its high-grade oxidized silver-gold deposits [10][14] Geological Context - The district's geology includes a mix of shallow-level oxidized Au-Ag and base metal deposits, with underexplored sulfide versions located below the water table [11] - The mineralization host rocks are primarily clastic sediments of the Cretaceous Bisbee Formation, underlain by Paleozoic carbonate formations [12] - Aztec believes the historic silver mines at Tombstone could be related to a larger mesothermal system with CRD mineralization below the old mines, indicating high prospectivity for further discoveries [13]
