Tribeca Resources Pre-Drilling Field Program Reveals Potential District-Scale Porphyry Epithermal Cluster At Jiguata Project

7 JULY, 2026 | VANCOUVER, BC – TheNewswire - Tribeca Resources Corporation (TSXV: TRBC) (OTCQB: TRRCF) (“ Tribeca Resources ”, the “ Company ”) is pleased to report technical updates from field programs completed at its Jiguata high sulphidation - porphyry copper exploration project in northern Chile (“ Jiguata ”, or the “ Jiguata Project ”), including geological mapping, soil and rock chip sampling, spectral and geophysical programs; together with a drilling update from its La Higuera Project (“ La Higuera ”, or the “ La Higuera Project ”). The recently completed pre-drilling field program at the Jiguata Project has generated geological, geochemical, spectral and geophysical datasets that the Company interprets as consistent with a district-scale porphyry and high sulphidation epithermal cluster. These are preliminary interpretations, with no assurance that they will be confirmed by drilling. Highlights: Jiguata Geological mapping and spectral interpretation have outlined large alteration footprints at the four distinct alteration centres, interpreted as potentially reflecting multiple intrusive centres across the project area. Spectral results show alteration patterns interpreted
