Aztec Drilling intercepts 2.31 g/t Au and 43.23 g/t Ag over 27.4 m at Tombstone

Step-Out Drilling Continues to Expand the Contention zone of Oxide Au/Ag Mineralization These drill holes expand the northern portion of the Contention target to the west and depth, with multiple mineralized zones Drill holes TR26 15-19 have encountered multiple mineralized zones expanding the northern Contention target area including intersections of 121.9 m averaging 0.29 gpt Au and 11.3 gpt Ag (0.50 gpt AuEq), 53.2 m of 0.78 gpt Au and 31.94 gpt Ag (1.36 gpt AuEq) and of 66.9 m averaging 1.05 gpt Au and 23.21 gpt Ag (1.47 gpt AuEq) 70 RC holes including 5 pre-collars and 8 core holes have now been drilled in the 2025-2026 drill program with 9 drill holes pending final analysis as the drilling campaign continues VANCOUVER, BC / ACCESS Newswire / May 14, 2026 / Aztec Minerals Corp. (TSX-V:AZT)(OTCQB:AZZTF) ("Aztec" or the "Company") announces the results from 5 drill holes from its reverse circulation ("RC") portion of the 2025-2026 drilling program at the Tombstone Property in Southeastern Arizona. Step out drilling expanding to the west and north Contention target area of the property has discovered additional strong, wide, shallow oxide gold-silver intersections. The Contention mineralized zone has been further extended to the west and to depth.

The 17,000m 2025-2026 drilling program has now completed 70 RC and 8 core drill holes. Highlights from the RC drilling reported for the Contention target include: Hole TR26-17 encountered multiple zones of oxide mineralization in the lower Bisbee sediments including 121.9 m averaging 0.29 gpt Au and 11.3 gpt Ag (0.5 gpt AuEq) from 82.3 m , including 12.2 m averaging 1.02 gpt Au and 14.54 gpt Ag (1.28 gpt AuEq), it TD'd in mineralization. TR26-17 demonstrated the continuity of mineralization in the northern end of the Contention target and expanded the po
