Aztec’s Tombstone Project Is a Gold Story Hiding in a Silver Town

Tombstone made its name on silver in the 1880s, yet roughly 70% of the metal value in Aztec Minerals’ drilling today is gold, with silver contributing about 30%. Most investors still look at the Aztec Minerals Tombstone project through a silver-town lens. The drill data suggests the market may be valuing a near-surface gold story instead.

That gap matters right now. As of 7 October 2026, Aztec Minerals has published neither a maiden resource nor a Preliminary Economic Assessment (PEA), which is an early study estimating whether a mine could make money. Management is targeting the resource for Q4 2026 and the PEA for 2027.

That leaves a short window to judge the story before the first official number lands.

Here is a practical framework for assessing an advanced-stage US precious metals explorer ahead of its maiden resource: what the land gives you, how to read the drill and metallurgy numbers together, where permitting gets harder, and how funding shapes the deeper upside. This is analysis, not investment advice. All figures come from company disclosures and third-party summaries.

What does roughly 2,500 consolidated acres in Tombstone actually give investors?

The headline number is about 2,500 acres of mineral and surface rights. Most of this is patented claims, which are mining claims converted to private land. Some Bureau of Land Management (BLM) ground sits alongside them, all surrounding the historic silver mines and a former open-pit heap leach that produced for about 10 years in the 1980s.

Acreage alone tells you little. The real value is that one company now controls the ground between old workings, so it can drill continuously across boundaries that once split the district between owners.

Arizona exploration activity has picked up as explorers secure new permits and consolidate ground, which suggests Tombstone’s land strategy is part of a wider Southwest shift rather than an isolated play.

The 2026 results show that advantage at work. In March, a Westside hole joined the Westside and Contention zones. By September, drilling on newly consolidated patented claims to the north had pushed the continuous oxide strike, meaning the drilled length of the mineralised zone, out by 255 m to more than 1,250 m.

Behind these results sit roughly 35,000 m of drilling over six years and 93+ reverse circulation (RC) holes by September 2026. That is a maturing dataset. It is still not a compliant resource.

Chief Executive Officer Simon Dyakowski has set expectations accordingly.

Management view Dyakowski has described the initial resource as a starting point, noting that no condemnation drilling (drilling to confirm ground is barren before building infrastructure on it) has yet been done and that growth remains the focus.

The widening, continuous strike tells you the market may eventually be pricing a district-scale oxide system rather than isolated pockets. Only a compliant resource will confirm that.

How do you read drill intercepts, metallurgy and a maiden resource target together?

Each headline number is one link in a chain. Knowing where each link can break is how you stress-test any explorer.

Every mineral resource estimate converts scattered drill intercepts into tonnes and grade through geological modelling, cut-off selection and classification, which is why the Q4 2026 release will reveal far more about continuity than any single hole has.

1. Drill intercepts. These prove metal exists at a given grade over a given width. They do not prove how much rock is mineralised between holes.
2. Metallurgical recovery. This shows what share of the metal a process can extract. Early tests do not prove the result holds across the whole deposit.
3. Maiden resource (NI 43-101). This is Canada’s reporting standard for an estimate of tonnes and grade with reasonable prospects of economic extraction. It does not prove the deposit can be mined profitably.
4. PEA. This tests rough economics. It carries wide cost error bars and does not prove a mine will be built.

Why equivalent grades move with metal prices

Gold equivalent (AuEq) and silver equivalent (AgEq) grades convert both metals into a single number using assumed prices. Aztec’s calculations reference gold near US$4,558/oz and silver near US$81/oz.

Change the prices and the equivalent grades change too. One technical outlook for October 2026 flags a head-and-shoulders top in gold, pointing to a rebound toward about US$4,275 and then a first downside target near US$3,920. That is one technical view, not consensus, but it shows how a softer gold price could shrink the AuEq figures that look strong today.

What bottle-roll tests can and cannot tell you

In January 2026, third-party testing of RC pulps returned 81.5% gold and 75.9% silver recoveries. Kappes, Cassiday & Associates ran the work using sodium cyanide (NaCN) bottle-roll tests, which agitate crushed samples in solution, following earlier shake tests.

The caveats are real. Drill-spacing bias can overstate grade, selected composites can overstate recovery, and clays, refractory material or transition and sulphide zones can complicate heap leaching.

Treat those recoveries as a promising starting range, not a PEA input. The signal to watch for is whether future column tests on varied samples confirm them.

Is private land really a permitting shortcut in a tourist town?

The company’s case is confident. Dyakowski argues that because the work sits on patented, private land, permitting runs at state level with no meaningful federal involvement, and the local team has been active in the area for 8-10+ years.

Management view Dyakowski has described the US as the foremost mining jurisdiction globally.

That claim holds up on federal process. It is weaker on everything that happens after the federal step drops away.

The advantages

• Avoids federal National Environmental Policy Act (NEPA) reviews, which can shorten timelines and reduce procedural uncertainty
• Clearer surface access supports multi-year drilling campaigns
• Local control simplifies roads, drill pads and small infrastructure

The caveats

• Arizona groundwater protection, reclamation bonding and facility design rules remain stringent
• Water availability and rights are a hard constraint amid competing users
• County zoning may restrict open pits or large processing plants near residential and tourist areas
• Heritage and tourism concerns over noise, traffic and visual impact can fuel strong opposition
• Proximity to a tourism town brings heightened scrutiny, litigation and ballot-initiative risk

No specific Arizona Department of Environmental Quality (ADEQ) Aquifer Protection Permit or reclamation milestones appear in 2024-2026 company materials. The 1980s heap leach shows the site has operated before. It is not a permit guarantee.

A shorter federal path does not mean a short path. You should weight water and zoning milestones as heavily as drill results, and read silence on state permits as a gap to track.

Where does the deeper CRD and porphyry upside fit, and what could go wrong?

Below the oxide cap, Dyakowski points to complex geology that could host silver, lead, zinc, copper and gold in carbonate replacement deposits (CRD), where hot fluids replace limestone with metal-bearing minerals, and possibly porphyry systems, which are large, lower-grade deposits tied to intrusions. Skarn and hydrothermal breccia intercepts at depth lend support.

The pull is understandable. Shallow oxide caps over deeper sulphide systems are common across Arizona and the Southwest.

Arizona porphyry and silver vein systems often sit beneath shallow oxide caps, which is the geological pattern behind the argument that Tombstone’s deeper sulphide potential deserves testing once the oxide is valued.

Yet only about four exploratory deeper holes have been drilled, and no named third-party geologists have commented on Tombstone’s deeper potential. The company plans to de-risk and revalue the oxide first, then fund a deeper phase over the next 12-18 months.

Funding and dilution

Aztec raised CAD 13.6 million across two 2025 placements and closed CAD 6.4 million in September 2026. Cash stood at about CAD 3.71 million on 30 June 2026, before that raise.

Share counts conflict across sources: roughly 188.9-189 million in mid-2026, later figures toward 211 million, and about 228 million fully diluted in analyst models. The September raise may explain part of the increase, though that is unconfirmed.

The four core risks are resource conversion, metallurgical variability, capex and dilution, and commodity timing. When the maiden resource lands, check:

1. Tonnes and classification, including how much is Indicated versus Inferred
2. Cut-off grade and price deck, and whether metal prices are conservative
3. Recovery evidence beyond bottle-roll tests
4. Permitting and water milestones disclosed alongside the resource
5. Funding runway relative to planned oxide and deeper work

The deeper upside is an option, not a base case. Value the oxide resource on its own merits and treat anything deeper as a bonus that may require more dilution.

Judging the maiden resource: what to check when the number arrives

Consolidation and oxide continuity at Tombstone look real. Metallurgy, permitting and funding will decide what they are worth.

When the Q4 2026 release arrives, test the classification, the price deck and the cut-off before the headline ounces. In the 2027 PEA, look for column-test recoveries, water and zoning progress, and a realistic capex figure.

Project economics assumptions such as price decks, recovery rates and capex drive early-stage valuations far more than headline grade, which is why a 2027 PEA needs to be read line by line.

Management frames the first estimate as a starting point, and no firm publication date exists beyond the Q4 2026 target. The next six to twelve months may show whether this district can be valued as a gold system first and a silver legacy second.
