Aztec Minerals Increases Drilling Program by 4,500 Meters and Commences Downhole Geophysical Survey of Core Holes at Tombstone Project, Arizona
Aztec Minerals pushes Tombstone exploration forward with a larger drill program and EM targeting, maintaining momentum in high-grade oxide zones ahead of CRD testing.
Executive Summary
- On 2026-03-10, Aztec Minerals Corp. announced a significant expansion of its Tombstone project drilling in the Arizona JV: an additional 4,500 meters of RC drilling, bringing the total planned program to approximately 17,000 meters of combined core and RC drilling.
- The expanded program has a CAD$1.7 million incremental budget and will focus on multiple Contention-area targets (Westside, Hard-up, Ingersoll, East Contention, Southeast Contention, Central Contention, and North Contention). The company also commenced downhole EM surveys on three core holes to bolster targeting for potential massive sulfide mineralization.
- This release follows a string of prior positive results (e.g., January 27, 2026 and February 2026 drill updates) that expanded oxide Au-Ag mineralization on strike and widened known zones, reinforcing the Tombstone district's prospectivity.
- The March 2, 2026 update reported 250-meter step-outs and widening mineralization in the Contention and Westside areas, consistent with a broader, shallow oxide gold-silver system.
- The prior updates in January and March 2026 highlighted the company’s ongoing drilling campaign expansion (from 8,500m to 12,000m early in 2026; then to 17,000m with the March 10 update) and the aim to test down-dip and horizontal extensions, as well as deep CRD targets.
Material Impact
- Directionality: Positive and in-line with an ongoing expansion narrative. The March 10 release formalizes a substantial ramp in drilling (4,500m) and the addition of downhole EM to improve targeting for possible massive sulfide systems, which could materially enhance discovery odds if success continues.
- Magnitude: The incremental CAD$1.7 million for 4,500m is material relative to a small-cap explorer and signals continued investor confidence to fund aggressive exploration. The move from 12,000m planned to 17,000m total adds meaningful drill footage and potential for high-impact results.
- Alignment with prior expectations: It is consistent with the company’s 2025-2026 drill campaigns that expanded oxide Au-Ag zones and pursued CRD targets, with EM surveys already being used as a targeting tool in the district. The EM component aligns with the CRD exploration thesis.
- Shares/dilution risk: Financing activity earlier in 2025 (upsized private placements and multiple equity financings) suggests ongoing dilution risk. While not explicit in the March 10 release, investors should consider potential cap-table impacts if further financings are required to sustain the expanded program.
- Strategic context: The Tombstone JV structure, recent JV ownership increase to 85% (end of 2025), and ongoing exploration across Contention-Westside zones reinforce a constructive narrative around district-scale exploration, with EM aiding CRD-targeting that could unlock deeper or parallel mineral systems.
- Conclusion on materiality: The March 10 update is material for near-term exploration execution and for signaling continued growth in the mineralized footprint and targeting precision. It’s not a sudden “game changer” in terms of resource sizing announced today, but it materially enhances the project’s near-term exploration cadence and discovery risk management.

Company Overview
- Aztec Minerals Corp. is focused on exploration-stage precious metals projects, with Tombstone in Arizona as its flagship project and Cervantes in Sonora, Mexico as a secondary project.
- Tombstone project: historic district with copper/lead/zinc/silver and significant silver-gold oxide mineralization; Aztec’s strategy is to expand shallow oxide gold-silver mineralization and to test deeper CRD targets below Contention and adjacent zones using RC and core drilling, aided by 3-D modeling and NSAMT/EM geophysics.
- Cervantes project: copper-gold porphyry system with exploration activity designed to define open-pit heap-leach potential and deeper porphyry sulfide targets.
