Metalero defines anomalies with survey at Benson

Executive Summary

• Metalero Mining reports anomalous copper‑gold soil results over >8 km² at the Cantin target on its flagship Benson project in the Quesnel Trough, BC.
• The ionic leach survey collected 344 samples on a 100‑m spacing, revealing coherent Cu anomalies defining a NNW trend and broad Au zones coincident with magnetic features.
• Results will guide further sampling, ground geophysics and drill targeting slated for the fall 2025 field season.

Key Details

• Survey Scope: 344 soil samples collected across the Cantin target; sample lines spaced 500–1,500 m apart; 100‑m sample spacing.
• Analytical Method: Ionic leach (static NaCN leach buffered to pH 8.5) for 61 elements; QA/QC performed at ALS Global, Vancouver, BC.
• Anomalies Identified:
• Multiple coherent copper anomalies defining a north‑northwest trend, open in all directions.
• Broad gold anomalism coincident with the Cu responses and airborne magnetic features.
• Strong correlation between Cu‑Au anomalies, mapped structural corridors/potential fluid pathways, and linear geophysical features.
• Target Area: >8 km² of soil anomaly coverage; located ~35 km NW of Mount Polley mine within the same structural corridor.
• Next Steps: Integration of soil results with geological and geophysical datasets to prioritize drill‑ready targets; additional fieldwork (sampling, ground geophysics) planned for fall 2025.
• Project Context: Benson project sits in the prolific Quesnel Trough, a >1,500 km long belt hosting >360 alkalic Cu‑Au porphyry occurrences and major mines such as Highland Valley, Mount Milligan, New Afton, and Kemess.
• Qualified Person Review: Technical content reviewed and approved by Michael Dufresne, MSc, PGeol, PGeo (non‑independent QP per NI 43‑101).

Notable Quotes

“These soil anomalies, covering greater than eight square kilometres and open in all directions, highlight the copper and gold potential at Cantin… The anomalies defined here will guide the next phase of exploration, including further sampling, ground geophysics and drill targeting, later in the 2025 field season.” – Rob L'Heureux, President & CEO, Metalero Mining Corp.
