Aztec drills 88.4 m of 1.42 g/t Au and 14.58 g/t Ag at Tombstone, Arizona

First Step-Out Drilling in Newly Acquired North Extension Zone has Expanded the Contention Zone of Oxide Au/Ag Mineralization to the North and at Depth

Drill hole TR26-39, stepping out into the North Extension Zone, encountered multiple mineralized zones including an intersection of 88.4 m averaging 1.42 g/t Au and 14.58 g/t Ag (1.69 g/t AuEq) from 10.7 m.

Contention Zone drillhole TR26-38 returned 97.5 m averaging 1.06 g/t Au and 16.08 g/t Ag (1.36 g/t AuEq) from surface.

VANCOUVER, BC / ACCESS Newswire / August 5, 2026 / Aztec Minerals Corp. (TSX-V:AZT)(OTCQB:AZZTF)(FRA:AZ3) ("Aztec" or the "Company") announces results from nine reverse circulation ("RC") drill holes, TR26-31 to TR26-39, at its Tombstone Property in southeastern Arizona. The holes include the first step-outs drilled into the recently acquired North Extension Zone, where TR26-33 and TR26-39 both intersected oxide gold-silver mineralization on ground not previously drilled by Aztec. TR26-39, one of the first two holes drilled into the North Extension Zone, returned 88.4 m averaging 1.42 g/t Au and 14.58 g/t Ag (1.69 g/t AuEq) from 10.7 m , and TR26-38 in the Contention Zone returned 97.5 m averaging 1.06 g/t Au and 16.08 g/t Ag (1.36 g/t AuEq) from surface .

Both intervals are the type of shallow, continuous oxide mineralization that Aztec is targeting at Contention - bulk tonnage material beginning at or near surface and potentially amenable to heap leaching. Each interval also carries a high-grade core, with 6.1 m averaging 12.23 g/t Au and 56.28 g/t Ag (13.25 g/t AuEq) in TR26-39 and 6.1 m averaging 12.17 g/t Au and 69.08 g/t Ag (13.43 g/t AuEq) in TR26-38. The near-surface oxide gold-silver zone remains open in all directions, including to the north and at depth.

Ninety RC holes have been completed in the 2025-2026 program as at the dat
