Orvana Argentina, a subsidiary of Orvana Minerals, has initiated a geophysical survey at the Taguas Project in the high Andes of San Juan province, Argentina.
The Taguas property comprises 15 mining concessions covering around 3,274 hectares (ha) within a renowned Andean mineral belt that hosts high-sulfidation epithermal gold-silver-copper and porphyry-style deposits.

Orvana Minerals is repositioning the project to focus on both the established and deeper mineralisation potential.
Orvana Minerals CEO Juan Gavidia said: “The 2025/26 campaign marks an important milestone in advancing our understanding of the Taguas mineral system.
“By combining the advanced geophysical survey now under way with insights from the recently completed review of historical exploration data, we will prioritise 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.”
Ridgeback Geofísica Argentina, an affiliate of Southernrock Geophysics, has been contracted to conduct the geophysical survey programme on the southern portion of the Taguas property.

By GlobalDataThis work will include magnetotelluric (MT) and induced polarisation (IP) surveys.
The MT survey will deliver three-dimensional subsurface resistivity models down to depths of roughly 1,500m, while the IP survey will develop chargeability models to shallower depths of approximately 800–1,000m.
These integrated techniques are expected to yield a clearer picture of the subsurface structure and guide the next phase of deep drilling, scheduled for early 2026.
Ridgeback and Southernrock Geophysics have substantial experience in high-resolution geophysical surveys across the Andes, contributing to better geological understanding at projects including Valeriano (Atex Resources) and Altar (Aldebaran Resources).
Their proficiency in deep-penetrating MT and IP methods offers a strong technical foundation for the Taguas programme and valuable regional insights into copper-gold systems, stated Orvana.
In addition to the geophysical work, complementary geological studies are also under way.
Comprehensive relogging of historical drill-holes, and short-wave infrared (SWIR) alteration analysis, have identified vectors towards porphyry-style mineralisation along a 2.5km north–south corridor from Cerro IV to Cerro Campamento.
This integrated workflow will enable Orvana to prioritise the most prospective zones for the forthcoming deep-drilling programme.
Orvana is a gold-copper-silver company with multiple operations. Its assets include the producing Orovalle operation in northern Spain and the Don Mario operation in Bolivia, which is currently undergoing plant expansion.
