Eastfield conducts grid expansion, line-cutting at Zymo

Executive Summary

• Eastfield Resources Ltd. provided a corporate review and update on its Zymo copper-gold porphyry project in British Columbia, highlighting significant historical drill intercepts and ongoing exploration activities.
• The company completed a private placement financing of $1.0 million in September 2025 to strengthen its treasury for future exploration.
• A five-year exploration permit was granted in December 2024, authorizing 50 drill sites and 50 kilometers of geophysical surveying, with a 2025 field program underway in preparation for a 2026 IP survey.

Key Details

• Project Overview: The principal asset is the 100%-owned Zymo copper-gold porphyry project, located near Smithers, B.C., covering 18,184 hectares.
• Exploration History: Over $4.9 million in exploration expenditures have been incurred since acquisition in 2007. To date, 34 diamond drill holes totaling 10,810 metres have been completed.
• Geological Significance: An eight-plus-kilometre-by-two-kilometre induced polarization (IP) anomaly outlines a copper-gold porphyry system with multiple one-kilometre-scale targets and coincident multielement geochemical anomalies.
• Significant Drill Intercepts:
  • Hole ZY08-09: 0.23% Cu and 0.32 g/t Au over 252 metres, including 0.44% Cu and 0.32 g/t Au over 159 metres, and 0.72% Cu and 0.55 g/t Au over 72 metres.
  • Hole ZY08-10: 0.31% Cu and 0.21 g/t Au over 159 metres.
  • Hole ZY11-20: 0.28% Cu and 0.34 g/t Au over 126 metres.
• Additional Mineralization: Peripheral precious metal veins have returned up to 10.78 g/t Au with several per cent lead and zinc.
• Current Status & Future Plans:
  • Mineralization occurs in porphyritic diorites and adjacent sediments with strong potassic alteration.
  • Five mineralized zones have been identified, including the Hobbes and FM zones.
  • Numerous IP targets remain untested, and no deep holes have been completed to date.
  • A 2025 field program involving grid expansion and line-cutting is currently underway.
  • The company is preparing for a 2026 IP survey.
• Financing: In September 2025, Eastfield completed a private placement financing of $1.0 million.
• Regulatory: The release was reviewed and approved by Glen Garratt, PGeo, the Qualified Person under National Instrument 43-101.
