Orvana Argentina Commences Geophysical Survey at Taguas Project, Argentina

TORONTO, Nov. 13, 2025 /PRNewswire/ -- Orvana Minerals Corp. (TSX: ORV) (the "Company" or "Orvana") announces that its Argentine subsidiary, Orvana Argentina S.A., has commenced a geophysical survey at its Taguas Project, located in the high Andes of San Juan Province, Argentina. The Taguas property consists of fifteen mining concessions totaling approximately 3,274 hectares, situated within a well-known Andean mineral belt hosting high-sulfidation epithermal gold-silver-copper and porphyry-style deposits.

The Company is repositioning the Taguas Project to evaluate its broader potential, extending beyond the near-surface oxidized gold-silver resource outlined in the 2021 Preliminary Economic Assessment (dated on December 29, 2021; available at www.sedarplus.ca) to include the underlying sulfide mineralization and potential deep porphyry copper-gold system.

"The 2025/26 campaign marks an important milestone in advancing our understanding of the Taguas mineral system. By combining the advanced geophysical survey now underway with insights from the recently completed review of historical exploration data, we will prioritize key targets for our initial deep drilling campaign, planned to start in January 2026, and establish a disciplined and strategic path toward unlocking the system's broader potential", said Juan Gavidia, Chief Executive Officer of Orvana Minerals Corp.

2025/26 Exploration Program

The Company's 2025/26 Exploration Program at the Taguas Project is structured into three sequential phases:

Phase	Objective	Status
Geological Modeling Update	Detailed relogging of historical drill holes and short-wave infrared (SWIR) alteration studies; spectral scanning of drill holes in the target area every 5m	Completed Identified vectors toward porphyry-style mineralization along a 2.5-kilometre north–south corridor extending from Cerro IV to Cerro Campamento
Geophysical Survey	Identify potential targets up to a depth of 1,500 m
