ETRUSCUS ADVANCES TOWARD PORPHYRY DISCOVERY AT ZAPPA TARGET, GOLDEN TRIANGLE, B.C.

Executive Summary

• Etruscus Resources reported results from its 2025 diamond drill program at the Zappa Porphyry Target (Rock & Roll Property, BC), completing 1,311 m in three holes.
• Hole RR25‑03 showed the strongest porphyry indicators—including elevated molybdenum, potassic alteration and quartz‑sericite‑pyrite (QSP) alteration—suggesting a concealed intrusion beneath the Twin Glacier to the northeast.
• Significant base‑metal mineralization was intersected in nearby North Gossan veins (up to 20.1 % Pb, 13.9 % Zn, 0.6 % Cu), expanding the prospectivity of the Bronson Porphyry Trend onto the property.

Key Details

• Program Overview: 1,311 m drilled across three holes (RR25‑01, RR25‑02, RR25‑03) targeting a large surface chargeability and alteration anomaly.
• Hole RR25‑01: Drilled northward; QSP alteration from surface to 151 m; up to 5 % pyrite disseminations; hole terminated at 344 m in black shales/lapilli tuffs.
• Hole RR25‑02: Drilled southward; intermittent QSP alteration (0‑32 m, 50‑62 m, 210‑228 m, 258‑274 m); potassic lithic clasts (~15 cm) at 310 m indicating proximity to a porphyry core.
• Hole RR25‑03: Collared on eastern edge of anomaly; alteration zones at 42‑56 m, 136‑188 m, 276‑368 m; intercepted a crystal tuff/porphyritic unit (276‑368 m) with weak‑moderate K‑feldspar alteration and chalcopyrite grains.
• Geochemical Highlights: Elevated Mo in QSP stockwork (136‑188 m) and altered andesite breccia (390‑484 m); REE enrichment (Ce, La, Nb, Y) in a quartz‑feldspar dike (0‑40 m).
• North Gossan Findings: 10‑30 cm wide quartz‑sulphide vein (~30 m strike) returned 0.3‑0.6 % Cu and Pb/Zn up to 20.1 %/13.9 %; pathfinder As, Ag, weak Au anomalies suggest extension of the hydrothermal system northward.
• Interpretation: Alteration and geochemical signatures indicate the porphyry intrusion likely lies northeast beneath the Twin Glacier; vectoring for future drilling is now focused in that direction.
• Next Steps: Plan to expand drilling NE under the Twin Glacier, continue mapping and geophysical work at North Gossan to define additional targets.

“Each step in a porphyry exploration program provides critical data to refine our understanding of the mineralized system… our first‑ever drill results at Zappa clearly show we’re on the right path.” – Fiore Aliperti, President & CEO

Materiality Assessment: Non-Material – Positive (exploratory drilling update that enhances project outlook but does not yet constitute a material financial event).
