Aztec Minerals (AZZTF) reported RC drilling results from five holes (TR26-40 to TR26-44) that extend the Contention gold-silver mineralized system at the Tombstone Project in Arizona by 255 meters, to over 1,250 meters of continuously drilled strike length.
All five holes intersected oxide gold-silver mineralization. Highlight results include TR26-41 with 83.8 m grading 0.90 g/t Au and 22.61 g/t Ag (1.31 g/t AuEq), including 7.6 m of 6.97 g/t Au and 75.42 g/t Ag (8.34 g/t AuEq), and TR26-43 with 51.8 m of 0.70 g/t Au and 25.59 g/t Ag (1.16 g/t AuEq), including 19.8 m of 1.93 g/t Au and 58.01 g/t Ag (2.99 g/t AuEq). Ninety-three RC holes have been completed in the 2025-2026 program, with assays pending for nine holes that are expected to feed into a maiden mineral resource estimate planned for the Tombstone Project.
Aztec Minerals (OTCQB:AZZTF) signed a definitive agreement, via subsidiary Aztec Minerals America, to acquire the final parcels in its Tombstone gold-silver district land consolidation in Arizona. The deal covers approximately 241 acres of surface rights and 414 acres of mineral rights over historic patented lode claims for US$241,000 in cash, subject to customary closing conditions.
Upon closing, Aztec’s Tombstone land position will total about 2,500 acres, up from roughly 398 acres when first optioned in December 2017.

Aztec holds an 85% interest in the Tombstone Joint Venture with Dragoon Resources (15%), which has contributed its share of completed acquisition costs. Dragoon has a 60-day right to participate in the newly agreed parcels on the same basis. Recent drilling on ground acquired in the program includes 88.4 m grading 1.42 g/t gold and 14.58 g/t silver (1.69 g/t AuEq) in hole TR26-39, with additional assays and a maiden mineral resource estimate targeted for late 2026.
Aztec Minerals (OTCQB:AZZTF) reported results from nine reverse circulation drill holes (TR26-31 to TR26-39) at the Tombstone Project in Arizona, including the first step-out holes in the newly acquired North Extension Zone. Key hole TR26-39 in the North Extension intersected 88.4 m grading 1.42 g/t Au and 14.58 g/t Ag (1.69 g/t AuEq) from 10.7 m, with a 6.1 m high-grade core of 12.23 g/t Au and 56.28 g/t Ag (13.25 g/t AuEq). In the Contention Zone, TR26-38 cut 97.5 m from surface averaging 1.06 g/t Au and 16.08 g/t Ag (1.36 g/t AuEq), including 6.1 m at 12.17 g/t Au and 69.08 g/t Ag (13.43 g/t AuEq), plus a second 106.7 m zone at depth, giving near-continuous mineralization from surface to 211.8 m. Aztec says 90 RC holes have been completed in the 2025-2026 program, with assays pending for 11 further step-out holes that are expected to feed into a maiden mineral resource estimate.
