Anteros samples one m of 1.44% Pb at Havens Steady

Executive Summary

• Anteros Metals Inc. released results from its first channel sampling program at the Havens Steady VMS property in Newfoundland, confirming and expanding surface polymetallic mineralization at the Main Mineralized Zone (MMZ).
• The results validate the geological model, showing continuity of lead-zinc-silver-gold-copper mineralization over approximately 750 metres of strike, with strong near-surface values supporting plans for future trenching and drill testing.
• The company also announced a corporate update extending the expiry date of 2,633,000 warrants by 12 months, though the exercise price remains unchanged.

Key Details

• Channel Sampling Results (MMZ):
  • Nine, four-metre-long channels were cut across the structure, yielding 36 one-metre samples.
  • Strongest intervals include:
    • 1.44% Pb, 0.90% Zn, 0.57% Cu, 0.35 g/t Au, and 51.6 g/t Ag.
    • 1.36% Pb, 0.04% Zn, 0.27% Cu, 0.54 g/t Au, and 47.7 g/t Ag over 1.0 metre within broader 3-4 metre wide zones.
• Historical Context & Continuity:
  • Results confirm and extend mineralization first modelled in the NHC zone (May 1, 2025) and validated by grab samples (July 3, 2025).
  • Previous grab sample HS-25-04 assayed 1.56% Pb, 9.60% Zn, 0.15% Cu, 45.0 g/t Ag, and 0.366 g/t Au.
  • Historical drilling defined the horizon with intercepts such as 4.0% Pb, 9.8% Zn, 37 g/t Ag, and 0.6 g/t Au over 6.0 m.
  • The broader MMZ remains open along strike to the northeast, where high-grade copper-gold-silver mineralization was discovered ~775 metres away (June 16, 2025).
  • Collectively, data highlights a mineralized corridor in excess of 800 metres of strike.
• Next Steps:
  • Plans to complete additional trenching and channel sampling along the MMZ strike and target areas for zone extension.
  • Prioritization of copper-rich zones where grab samples returned up to 2.17% Cu, 21.3 g/t Ag, and 0.22 g/t Au.
  • Integration of data to refine Phase 1 drill targets for subsurface continuity testing.
• Warrant Extension:
  • Expiry date extended for 2,633,000 warrants by 12 months.
  • New expiry date: November 27, 2026.
  • Exercise price remains 20 cents per common share.
• Analytical Methods:
  • Samples submitted to Eastern Analytical Ltd. (ISO/IEC 17025-accredited).
  • Multielement geochemistry via ICP-OES; overlimit Pb, Zn, Ag via AAS; Gold via 30g fire assay with AAS finish.

Notable Quotes

• "These inaugural channel results demonstrate that mineralization at the MMZ extends to surface, consistent with our geological model. The continuity and multimetal nature of the results support the MMZ, modelled to be a wide, laterally extensive and high-grade zone, as a compelling follow-up target for trenching and drill testing." — Trumbull Fisher, CEO
