Orvana Minerals Corp. Initiates Geophysical Survey at Taguas Project

Orvana Minerals Corp. (TSX: ORV) has officially started a geophysical survey at its Taguas Project, located in the breathtaking Andes of San Juan Province, Argentina. This move is part of the company's strategic plan to unlock the broader potential of the project, which encompasses fifteen mining concessions covering around 3,274 hectares. The region is known for hosting significant deposits of gold, silver, and copper.

In light of the growing interest and intricate nature of the mineral resources in the area, Orvana is taking steps to re-evaluate the Taguas Project. The company is keen on scrutinizing its existing oxidized gold-silver reserves while exploring deeper into the underlying sulfide mineralization and the promising copper-gold porphyry system.

Strategic Importance of the Survey

As highlighted by Juan Gavidia, CEO of Orvana Minerals Corp., the ongoing geophysical survey represents a crucial milestone in enhancing the company's understanding of the Taguas mineral system. This 2025/26 campaign will consolidate insights from recently reviewed historical exploration data with advanced geophysical methods, all aimed at identifying priority targets for a deep drilling campaign scheduled to commence in January 2026.

The exploration program for 2025/26 is structured into three key phases:

1. Geological Modeling Update: The company is meticulously re-examining historical drill cores and utilizing short-wave infrared (SWIR) alteration studies to identify vectors toward porphyry-style mineralization along an expansive north-south corridor, stretching approximately 2.5 kilometers from Cerro IV to Cerro Campamento. This phase has already been completed, yielding promising results.
2. Geophysical Survey: Ongoing efforts aim to identify significant targets up to a depth of 1,500 meters. Currently underway and expected to conclude by late December 2025, the survey encompasses a 4 square kilometer area between Cerro Campamento and Cerros Taguas with a detailed grid layout.
3. First Deep Drilling: Planned for early 2026, this phase will focus on drilling areas exhibiting potential indicators of a copper-gold porphyry system, as established by the geophysical findings and updated geological models. The preliminary plan suggests a drilling length of around 4,500 meters, subject to refinement based on real-time results.

These measures are designed to ensure that Orvana can advance methodically while concentrating on the most promising areas for deep drilling.

Comprehensive Geophysical Survey Techniques

For the purposes of this survey, Orvana has partnered with Ridgeback Geofísica Argentina S.A., a subsidiary of Southernrock Geophysics. This collaboration focuses on executing an extensive geophysical survey program, employing advanced techniques such as Magnetotelluric (MT) and Induced Polarization (IP) surveys. The MT survey is crucial for constructing three-dimensional models of subsurface resistivity down to depths of 1,500 meters, while the IP survey will generate chargeability models at shallower depths, offering a comprehensive view of the subsurface structures.

The implementation of these sophisticated geophysical methods is backed by Ridgeback's extensive experience in the Andes, having contributed insights to various project locations, notably improving understanding at the Valeriano and Altar projects.

The integration of rigorous geological examinations, detailed historical drill hole relogging, and advanced geophysical mapping positions Orvana to strategically prioritize the most prospective regions ahead of the imminent deep-drilling program.

Future Directions

The exploration program at Taguas aligns seamlessly with Orvana’s overarching strategy of enhancing long-term value through tactical explorations and capital allocation efficiency. The insights gleaned from this campaign will be pivotal in refining the geological model, validating priority targets, and charting the path forward for the future development of the project. As they embark upon the detailed exploration of Taguas, Orvana remains committed to thoughtfully addressing the challenges and opportunities embedded within the mineral landscape of Argentina.
