Drill holes TR26-45 to TR26-53 encountered multiple mineralized zones including 115.8 m averaging 0.52 g/t Au and 8.11 g/t Ag (0.67 g/t AuEq) from 51.8 m depth in TR26-45, 30.5 m averaging 0.70 g/t Au and 24.62 g/t Ag (1.15 g/t AuEq) from 82.3 m depth in TR26-49, and 24.4 m averaging 0.76 g/t Au and 14.59 g/t Ag (1.02 g/t AuEq) from surface in TR26-48, in step-out holes drilled west of the North Extension target
Beyond the Headline
Aztec Minerals released results from nine (9) additional RC holes (TR26-45 to TR26-53) on
its 85% owned Tombstone Property Joint Venture in southeastern Arizona. The main target
of the current drilling was to continue testing the shallow, bulk tonnage, potentially heap
leachable, mesothermal gold-silver oxide mineralization adjacent and below the previously
mined Contention pit by step-out drilling (Figure 2-1). All nine holes intersected oxide gold-
silver mineralization, extending the North Extension footprint as much as 190 m westward.
Significant results are as follows:

Mineralization is associated with altered dioritic dikes, hydrothermal breccias and quartz
fissure structures cutting Bisbee Group rocks and underlying carbonates. These controls
resemble those recognized at the Main Contention zone.
The continuity of oxide mineralization westward suggests potential for a larger mineralized
footprint than previously outlined. However, grades are variable, and some holes
intersected relatively narrow higher-grade zones separated by lower-grade material.
Twenty-two (22) additional holes are awaiting assays. A maiden mineral resource estimate
is expected in November 2026, but it will incorporate results only through TR26-44. The
latest nine holes therefore represent potential additions for a subsequent resource update.
Comments
These are encouraging results, especially the 190m westward expansion. The
oxide character and relatively shallow mineralization are attractive for potential open-pit
development, although metallurgical recoveries and continuity of economic grades need to
be confirmed. I would recommend pushing the mineral resource estimate (MRE) back to
Q1 2027 so that all new drill holes can be included in the MRE.
