Orvana Argentina Commences Geophysical Survey at Taguas Project, Argentina

Executive Summary

• Orvana Argentina has commenced a Magnetotelluric (MT) and Induced Polarization (IP) geophysical survey at the Taguas Project, covering ~4 km² to depths of up to 1,500 m.
• The survey is part of the 2025/26 exploration program that also includes completed geological modeling work identifying a 2.5‑km north–south corridor with vectors toward porphyry-style mineralization.
• Results from the geophysical work will guide an initial deep‑drilling campaign slated for early 2026, targeting approximately 4,500 m of drilling on priority copper‑gold porphyry targets.

Key Details

• Project Scope: Taguas Project comprises 15 mining concessions (~3,274 ha) in the high Andes of San Juan Province, Argentina, within a known epithermal gold‑silver‑copper and porphyry belt.
• Geophysical Survey Provider: Ridgeback Geofísica Argentina S.A., an affiliate of Southernrock Geophysics, engaged to conduct MT and IP surveys.
• Survey Coverage & Design: 4 km² area between Cerro Campamento and Cerros Taguas; grid spacing 400 m × 400 m.
• Depth Targets: MT survey – resistivity models to ~1,500 m depth; IP survey – chargeability models to ~800–1,000 m depth.
• Geological Modeling Update (Completed): Relogging of historic drill holes and SWIR alteration studies performed every 5 m; identified vectors toward porphyry mineralization along a 2.5‑km corridor from Cerro IV to Cerro Campamento.
• Exploration Program Phases:
• Phase 1 – Geological Modeling (completed).
• Phase 2 – Geophysical Survey (in progress, expected completion late Dec 2025).
• Phase 3 – First Deep Drilling (planned start early 2026; ~4,500 m total, subject to change based on survey results).
• Strategic Intent: Refine the geological model, test priority porphyry targets, and generate data to inform future resource delineation and project advancement decisions.
