Vancouver, Canada – March 2, 2026 - Aztec Minerals Corp. (AZT: TSX-V, OTCQB: AZZTF) (“Aztec” or the “Company”)
announces it has received the results from an additional five drill holes from its reverse circulation (“RC”) portion of
the 2025-2026 drilling program at the Tombstone Property in Southeastern Arizona. The 2025-2026 drilling program
has now completed 53 RC and 5 core drill holes. The results from the final 5 RC holes drilled in 2025 are announced
herein. The successful drilling of the step out drill holes of the Contention pit area have joined the Main and South
target zone s and the main zone to the Westside and Westside Anticline t arget areas. These are important
unifications and expansions of the shallow oxidized gold -silver mineralized zones of the Property. These strong,
wide, shallow oxide gold-silver intersections have extended the Contention Au/Ag zone from the northern property
limit to now over 1km N-S on strike and approximately 0.4km of width into the Westside area. Pending drill results
include additional Westside area drill targets as well as several step out targets drilled in the immediate , westerly
and deeper extensions of the Main Contention zone.
Highlights from the RC drilling reported include the southern portion of the Contention and the Westside t argets
include:
• Drill hole TR25-34 intersected 40.2m averaging 1.09 gpt AuEq (0.99 gpt Au and 6.9 gpt Ag) including 4.6m
of 9.861 gpt AuEq (9.569 gpt Au and 20.43 gpt Ag) of oxidized mineralization. This drill hole was collared in
the northern portion of the Property to the east of TC25-03 as a step out from the Westside area.
Mineralization found in it connects to the east with the Main Contention zone. Drilled to 243.9 m depth, it
has five mineralized zones from collar to end.
• Drill hole TR25-36 intersected 44.1m averaging 0.86 gpt AuEq (0.221 gpt Au and 44.64 gpt Ag), including
65.3-71.4m, 6.1m averaging 3.724 gpt AuEq (0.905 gpt Au and 197.37 gpt Ag). This drill hole was collared
200 m east from TR25-35 and the mineralization was encountered in the Bisbee sediments at 56.2-100.3m.
TR25-36 represents a significant step out from the Main Contention zone, by over 250m to the West from
the prior drilling in 2024.
• RC drill hole TR25-33 intersected five mineralized zones including 42.6m averaging 0.452 gpt AuEq (0.257
gpt Au and 11.5 gpt Ag) of oxidized mineralization over its 152 m depth. The drill hole was collared on the
unmined land bridge marking the limit between the Contention Main and South pits. Along with TR25-32
this drill hole has defined and joined the Contention Zone mineralization over its plus one-kilometer length
identified to date.
All of the fiv e RC drillholes reported herein intersected Ag -Au mineralization and joined portions of and also
expanded the Contention and Westside target areas to the west and to depth. The intercepts show broad continuity
of mineralization. All reported intersection lengths are apparent widths of mineralization, not true widths, which
can range at the property from 30% to 100% of apparent widths.
Aztec Minerals CEO Simon Dyakowski Commented: “Today’s announcement of successful step out drilling in the
Westside target area of the Tombstone property marks a significant milestone for the project. Drilling conducted in
late 2025 has not only extended the strike length of the Main Contention Zone to over one kilometre north- south,
but we have also now demonstrated wi dth of the North Contention Zone to over 350 meters. Shallow gold -silver
oxide mineralization encountered in drill hole TR25-36 further extends the target area to the West. With continued
drilling of step out targets to the West of the main contention Zone the project’s scale continues to grow as we
continue our largest ever drill campaign at the project, which is currently planned at appro ximately 12,500 meters
of combined RC and core drilling.”

Core Drilling Update
The core drilling portion of the program in 2026 continues with drilling ongoing in the 3rd deeper core hole TC26-02
targeting a strong NSAMT anomaly in the Southwest of the property. Drill hole TC25-04 targeting the large, southern
NSAMT target was recently completed at 831.7 m depth ; however, was terminated by drillhole caving above the
planned total depth of 1000m . TC25-04 encountered mild to moderate strength retrograde exoskarns in the
hornfels of the lower Cretaceous basal Bisbee siliciclastic sediments at 575 m depth and it continued for the rest of
the drillhole. The skarns are typified by epidote and chlorite with asso ciated hematite staining. The skarns are
accompanied by several silicified hydrothermal breccia dikes with occasional Qfp clasts and with evidence of
potential “B-type” porphyry veinlets over that thickness . The skarns are notably more competent rock than the
hornfels. The underlying Paleozoic Naco Formation limestones were encountered at 783.8 m depth in TC25-04.
Core drilling to -date has confirmed the NSAMT target as based on a geologic (Skarn) anomaly within the upper
portion of the NSAMT target. It was planned to continue drilling to depth in TC25 -04; however, drillhole caving
terminated the hole. The core rig was then moved to drill TC26-01 to test to the west and below of TR21-12 but due
to poor ground conditions and the completion of the RC precollar for TC26-02 the core rig was moved onto TC26-02
and it is currently at 528 m depth drilling to test the southwestern NSAMT target. TC26-02 has intercepted skarning
and sulfides recently as well. Aztec has previously identified several large, strong, conductive bodies, underneath
the historic gold -silver district through NSAMT (natural -source audio -frequency magneto -telluric surveys)
anomalies1.
The continued, successful drilling of the Contention pit area was supported by Aztec’s 3D geologic and underground
workings model that was constructed to assist in targeting potential expansion of the Contention system. The overall
Contention system has yet to be defined and marks the confluence of other mineralized zones including the Westside
Anticline.
Detailed Drillhole Summary Highlights (see Table 1 & 2 below):

The 52 RC drill holes in the current 2025-26 program completed to date primarily are part of a “fan grid pattern”
being drilled in the Contention area since 2020. Most of the RC drill holes are oriented to test for extensions on the
western, eastern borders, the southern extensions, and underneath the north-trending main Contention target zone
which hosts the historic underground and open pit Contention mine. Several RC drill hole s tested targets in the
Westside area on projected anticline, dike and fissure vein intersection under mineralized outcrops and historic
shafts. The drill program has continued to identify to depth and horizontally pervasively oxidized and hematite-rich,
silicified hydrothermal breccias composed of quartz feldspar porphyry dike and Bisbee Group clastic sedimentary
fragments, typical of the material mined historically at the Contention Mine.
Additional mineralization types continued to be outlined by the current drilling including: manganese replacements
in limestone beds and skarns, quartz veinlets, oxidized sulfide relicts as disseminations, silicification of altered
hornfels, quartz feldspar porphyries and hydrothermal breccias. For the 2025 program, TR25-09 was the deepest
RC hole drilled, it has an inclination of -60 degrees and was drilled to a depth of 274.4m (237.7 m vertical) remaining
in mineralized and oxidized rocks most of its length.
The drilling results showed that the Contention area mineralization is still open at depth and the mineralized volume
is expanding.
2025-2026 RC and Core Drill Program
The RC drilling program is targeting shallow zones associated with surface exploration and 3D geological modelling,
prospective for wide oxide gold -silver mineralization, and drilling pre -collars for the deeper CRD target s. The drill
program has completed 40 RC and RC precollar drill holes in 2025 and 1 3 RC and RC precollar drill holes since the
start of 2026, focusing on testing both the Contention Main and Southern Extension area s as step out targets and
Westside Area first pass target s, with results from the first 40 holes now announced. Initial assay results continue
to validate the oxide gold-silver geological setting as outlined in Aztec’s geological exploration model. Five core holes
(TC25-01, 02, 03, 04 and TC26-1) have been completed and another (TC25 -02) is currently being advanced (528 m)
testing the southwestern AMT target.
The primary objectives of the 2025 drilling program were to: Expand the known mineralization horizontally to the
west, north and south, and down dip beyond the holes drilled by Aztec in 2020 -24 at the Contention Pit with step
outs to enlarge the shallow, broad, bulk tonnage gold-silver mineralization discovered there; test by core drilling the
initial deep CRD targets and also, to explore with first pass drilling new targets identified in the Westside area.
