Aztec Drills 1.08 gpt Au and 30.23 gpt Ag (1.63 gpt AuEq) over 155.4 meters, Expands Oxide Gold-Silver Zone at Tombstone Project, Arizona

Aztec Minerals Corp. (AZT) released results from its 2025-2026 Tombstone program, highlighting hole TR26-30. The hole intersected 198.1 m @ 0.86 g/t Au, 24.52 g/t Ag (1.30 g/t AuEq) from surface, including 155.4 m @ 1.08 g/t Au, 30.23 g/t Ag (1.63 g/t AuEq) from 6.1 m. A high-grade core of 44.2 m @ 1.50 g/t Au, 60.51 g/t Ag (2.60 g/t AuEq) and a 6.1 m pocket of 9.54 g/t Au, 35.03 g/t Ag (10.18 g/t AuEq) are noted. The hole reportedly extends oxide mineralization vertically by over 85 m, more than doubling the previously demonstrated depth.

Additional RC holes at Independence, Hard Up, and East Grand Central targeted step-outs but returned low-grade to modest intercepts. These included: - 22.9 m @ 0.13 g/t Au, 13.04 g/t Ag - 10.6 m @ 0.34 g/t Au, 19.36 g/t Ag

Core drilling updates showed TC25-03 hit a narrow CRD zone (4.6 m @ 0.64 g/t Au, 2.65 g/t Ag, 0.21% Pb), while TC25-04 encountered 32.0 m @ 0.26 g/t AuEq with a 3.0 m Pb-Ag rich sub-interval. The program status stands at 84 RC holes completed and 9 core holes attempted.

Aztec Minerals Corp. (AZT) is a pre-resource explorer, meaning any drilling that materially expands its footprint and advances toward a maiden resource is considered significant. The TR26-30 drill hole’s 85 m vertical extension suggests the oxide zone is much thicker than previously known, which could meaningfully increase the potential resource tonnage at the Contention target.

However, uncertainty regarding true width, cutoff, and AuEq transparency reduces immediate confidence. The market had already priced in a large system, given the company’s C$42M market cap and extensive historical bonanza-grade hits. The stock barely moved on prior thick intercepts, such as the May 14 release, and has been in a downtrend.

The news represents an expected step-out that supports the resource growth narrative rather than a game-changing event. While the scale and depth extension are genuinely new and market-relevant, disclosure gaps and the single-hole nature of the result prevent a stronger classification. The finding remains an encouraging, de-risking result rather than a transformational discovery.

Aztec Minerals Corp. (TSXV: AZT; OTCQB: AZZTF) is a junior explorer holding an 85% joint venture interest in the Tombstone Project in Arizona and 100% ownership of the Cervantes porphyry gold-copper project in Sonora, Mexico. The Tombstone deposit features a shallow oxidized gold-silver system adjacent to the historic Contention pit, with drilling extending over a strike of more than 1 km and to depths exceeding 265 m. The company currently has no resource estimate for Tombstone, with a maiden mineral resource estimate targeted for the third quarter of 2026.

At the earlier-stage Cervantes project, drill results include intercepts such as 137 m @ 1.49 g/t Au, and a maiden mineral resource estimate is also underway. Aztec Minerals is debt-free, reporting C$4.5 million in cash as of June 2026 following a presentation. The company recently completed a C$10 million bought-deal financing. Operating cash burn is offset by equity raises, and the company currently generates no revenue.
