Etruscus Resources talks drilling at Zappa

Executive Summary

• Etruscus Resources released results from its inaugural 2025 diamond drill program at the Zappa porphyry target on the Rock & Roll property in the Golden Triangle, B.C., totaling 1,311 metres across three holes.
• The drilling successfully identified strong porphyry indicators, including potassic alteration, elevated molybdenum, and quartz-sericite-pyrite (QSP) alteration, suggesting the company is vectoring closer to a potential mineralized porphyry intrusion.
• Hole RR25-03 provided the strongest evidence of proximity to a heat source, with geochemical and lithological data pointing to a concealed porphyry intrusion beneath the Twin glacier to the northeast, which is the focus for future drilling.

Key Details

• Program Overview: Inaugural 2025 drill program at Zappa target; 1,311 metres total drilled across 3 holes (RR25-01, RR25-02, RR25-03).
• Hole RR25-01:
  • Drilled 344 metres.
  • Encountered quartz-sericite-pyrite (QSP) alteration from surface to 151 metres with up to 5% pyrite disseminations.
  • Targeted high chargeability anomaly likely correlated to sulphide-rich hydrothermal alteration and graphitic black shales.
• Hole RR25-02:
  • Drilled to target strong surface alteration.
  • Encountered sporadic QSP alteration in intervals: 0-32m, 50-62m, 210-228m, and 258-274m.
  • Identified intense zones with up to 5% pyrite and multiphase quartz veining.
  • At 310m, identified multiple potassically altered lithic clasts (up to 15cm) in lapilli tuff, indicating a nearby porphyry core.
• Hole RR25-03:
  • Drilled north underneath the Twin glacier; identified hydrothermal alteration at 42-56m, 136-188m, and 276-368m.
  • Intercepted a unique unit (crystal tuff or faintly porphyritic intrusion) from 276-368m containing weak to moderate potassium feldspar alteration adjacent to sericite veinlets.
  • Confirmed high-temperature alteration via elevated potassium geochemistry and rare chalcopyrite grains.
  • Elevated Molybdenum (porphyry halo indicator) in QSP stockworked quartz zone (136-188m) and altered andesite breccia (390-484m).
  • Intercepted quartz feldspar porphyry dike (0-40m) with elevated Rare Earth Element (REE) values (Ce, La, Nb, Y), suggesting a highly evolved magma similar to the Pheno claims.
• North Gossan Exploration:
  • Located 1km north of Zappa; 900-metre strike length of argillic/clay-altered felsic volcanics.
  • Elevated pathfinder elements (Arsenic, Silver) and weakly anomalous gold suggest connection to the Zappa system.
  • Identified quartz-sulphide vein (10-30cm wide, 30m length) returning up to 20.1% Lead, 13.9% Zinc, and 0.6% Copper.
  • Propylitic alteration identified between North Gossan and Zappa target supports hypothesis of a larger porphyry centre.
• Next Steps: Expand drilling northeastward beneath the Twin glacier; continue mapping and geophysics at North Gossan.

Notable Quotes

• "Each step in a porphyry exploration program provides critical data to refine our understanding of the mineralized system. The identification of potassic and QSP alteration is a strong indicator that we're close to the heart of the system, a significant advancement in our exploration. Several nearby discoveries in the Golden Triangle required multiple programs to vector in and locate mineralized zones, and our first-ever drill results at Zappa clearly show we're on the right path." — Fiore Aliperti, President and CEO
