Etruscus releases Hendrix rock sampling results

Executive Summary

• Etruscus Resources Corp. released surface rock sampling results from its 2025 exploration program at the Hendrix rare earth element (REE) target on the Pheno property in British Columbia.
• The program identified three highest-grade REE rock samples to date at Pheno, with significant enrichment in neodymium and dysprosium, and outlined REE-bearing dikes within a five-kilometre-wide peralkaline volcanic complex.
• A specific four-metre-wide by 70-metre-long dike returned an average of 0.39% total rare earth oxides (TREO), while other zones showed 2,000 to 5,000 ppm TREO, highlighting the economic potential of heavy REEs in a geopolitically sensitive market.

Key Details

• Sampling Scope: 83 rock samples taken across the ~5 km wide peralkaline volcanic complex at the Hendrix target.
• Key Intercept: A four-metre-wide-by-70-metre-long dike (open at depth beneath ice) returned an average of 0.39% TREO from six grab samples.
• Grade Ranges: Dikes returned between 2,000 and 5,000 parts per million (ppm) TREO from rock grab samples.
• Elemental Enrichment: Significant enrichment in neodymium and dysprosium (heavy REEs); also associated with niobium and scandium.
• REE Ratio: The Hendrix target contains a significantly above-average ratio (0.30) of heavy REEs versus light REEs, which are scarcer and economically more significant.
• Geological Context: Dikes are vertically emplaced, ranging from 0.5 to 4 meters in width, hosted within REE-bearing peralkaline tuffs and rhyolites.
• Geochemistry: Positive relationship identified between zirconium (Zr) and TREO; magmatic fractionation interpreted to have concentrated REEs (supported by Rb/Sr and Zr/TiO2 indices).
• Analogue: Closest analogue identified as the Round Top deposit in Texas (owned by USA Rare Earths, market cap >$2 billion USD).
• Technology: Implemented hand-held Geiger counters in 2025 for real-time gamma ray detection to identify new REE-rich dikes; evaluating airborne radiometric surveys for future use.
• Lab Analysis: Samples assayed by ALS Geochemistry Labs using lithium borate fusion (package ME-MS81) for full digestion of REE minerals.

Notable Quotes

• "The identification of multiple REE-bearing dikes at Pheno represents an important step forward in advancing this very large target. We are looking forward to returning in 2026 to expand on these results, refine our targeting and continue evaluating this consistently mineralized, near-surface target." — Fiore Aliperti, CEO
