Hayasa highlights NSAMT results for Urasar project

Executive Summary

• Hayasa Metals received final NSAMT (natural source audio magnetotelluric) data from a three‑line, 26‑station survey over the western “Yellow River” zone of its Urasar copper‑gold project in Armenia.
• The resistivity model shows low‑resistivity anomalies near the river valley that may indicate undiscovered sulphide‑rich zones, as well as high‑resistivity zones paired with discrete lows at the north end correlating with 2024 IP chargeability highs.
• Management plans to incorporate these results into a 2026 drilling program targeting deeper holes, especially at Copper Creek, pending assay results from the recent 2,040 m drill campaign completed in July 2025.

Key Details

• Survey execution: Conducted by Terratec Geophysical Services GmbH & Co. (Germany) in July 2025; three north‑south lines spaced ~1.1 km apart across the Yellow River zone, offset 500–600 m from June 2024 IP lines.
• Geophysical findings:
• Low‑resistivity anomalies at southern ends of profiles adjacent to river valley, extending northward where surface alteration and mineralization are present.
• Discrete low‑resistivity zones suggest possible sulphide‑rich targets that recent drill holes may have missed.
• High‑resistivity zones with embedded lows at northern ends correspond to high chargeability anomalies from the 2024 IP survey.
• Drill program context: 2,040 m of drilling completed in July 2025; assay results expected in coming weeks. Recent holes (UDD‑016, UDD‑017) intersected up to 40 m of massive sulphide mineralization at the Black River target.
• Management comments:
• Dennis Moore (President/Qualified Person) notes structurally complex controls on mineralization and highlights potassic and actinolite alteration in Yellow River core, suggesting a possible porphyry system at depth.
• Joel Sutherland (CEO) points to Figure 3 indicating potential for deeper drilling at Copper Creek in 2026, contingent on forthcoming assay data.
• Future plans: 2026 exploration program will focus on testing large, untested geophysical anomalies—particularly north of the current focus area—with multiple deep drill holes.

Notable Quotes

“Our work to date indicates that the controls on mineralization at Urasar are structurally complex despite being situated within a well‑defined east‑west corridor.” – Dennis Moore, President & Qualified Person

“Figure 3 makes a good case for a deeper hole at Copper Creek in 2026, particularly if the assays confirm what we can see visually in the core.” – Joel Sutherland, CEO
