Aztec Drills 556.5 gpt Silver and 17.7 gpt Gold (2149.5 gpt AgEq) over 3.04m within 70.8 gpt Ag and 1.99 gpt Au (250.2 gpt AgEq) over 28.9m; Continues Expansion of the Contention Target and Drilling for Potential CRD Mineralization at the Tombstone Projec

Executive Summary

• Aztec Minerals announced high‑grade silver‑gold intersections, notably TR25‑06 with 2,149.5 gpt AgEq over 3.04 m and TR25‑05 with 590.4 gpt AgEq over 4.6 m.
• The JV Management Committee approved expanding the 2025 reverse‑circulation (RC) program from 5,000 m to 7,500 m, now targeting an end‑Q4 2025 completion.
• To date 19 RC holes (3,414.3 m) have been completed; results confirm the Contention mineralization remains open laterally and at depth, supporting a bulk‑tonnage, potentially heap‑leachable oxide Au‑Ag target.

Key Details

• Drillhole TR25‑06 (Little Joe Area) – 3.04 m @ 2,149.5 gpt AgEq (556.5 gpt Ag, 17.7 gpt Au) within a broader 28.9 m zone averaging 250.2 gpt AgEq. Depth: 76‑105 m.
• Drillhole TR25‑05 – 4.6 m @ 590.4 gpt AgEq (238.7 gpt Ag, 3.91 gpt Au) within a 47.1 m zone averaging 85.5 gpt AgEq. Depth: 3‑50 m.
• Drillhole TR25‑08 – Two zones: 74.5 m @ 36.4 gpt AgEq (19.8 gpt Ag, 0.184 gpt Au) and 31.9 m @ 13.7 gpt AgEq (6.0 gpt Ag, 0.085 gpt Au).
• Drillhole TR25‑07 – Multiple intervals totalling ~84 m with grades ranging 9.3–22.6 gpt AgEq; mineralization remains open westward and to depth.
• Program Expansion: Approved increase to 7,500 m (from original 5,000 m), now projected to finish by end of Q4 2025.
• Overall Progress: 19 RC holes drilled (3,414.3 m); additional results from five newly announced holes pending.
• Geological Context: Intersections validate the oxide Au‑Ag model; drilling continues to test shallow bulk‑tonnage zones and deeper CRD targets beneath the historic Contention pit.
• Assay Methodology: Samples taken every ~1.5 m, analyzed by Bureau Veritas (FA430 method, with MA300/MA370 follow‑up). QA/QC program includes blanks, standards, duplicates.

Notable Quotes

“The high‑grade silver‑gold intersection drilled in TR25‑06 demonstrates the continued discovery of high‑grade precious metal mineralization that the historic Tombstone Silver District is best known for… We are eagerly awaiting additional results and are pleased to announce the expansion of drilling to what is now expected to be our largest ever campaign on the back of strong initial assay results.” – Simon Dyakowski, CEO
