Orvana Minerals Reports On Progress In Taguas Drilling Campaign Including Key Assay Results

Orvana Minerals Provides Update on Taguas Drilling Campaign

Orvana Minerals Corp. recently revealed significant developments from its ongoing drilling operations at the 100%-owned Taguas Project in Argentina. The results, which come from their 2026 drilling campaign, indicate promising high-grade gold and copper mineralization, particularly from the drill hole TADD-279.

Key Results from the Drilling Campaign

The assay results from TADD-279 showcased several significant intercepts, most notably an interval of 1.25 meters, grading 9.19 g/t gold and 5.55% copper. This discovery underlines the vertical continuity of the hydrothermal system, indicating that the high-sulfidation epithermal system remains mineralized at considerable depths. Additionally, measurements from VNIR–SWIR Terraspec revealed the development of sericitic alteration at depth, which is consistent with the alterations observed in TADD-278, further supporting the theory of a persistent hydrothermal system.

Raúl Álvarez, Director of Exploration and Technical Services at Orvana, stated, “The results from TADD-279 ... reinforce our interpretation that we are vectoring toward the core of a hydrothermal system potentially linked to a deeper porphyry source.” This statement reflects the geological potential that exists as they plan to extend drilling to explore this connection better.

Continuous Exploration and Future Plans

Moving forward, Orvana is focusing on completing detailed petrographic studies on TADD-279 while integrating all drilling data from this campaign with historical datasets. This integrated approach aims to refine the geological model and to support planning for future exploration campaigns. A technical workshop is also set to take place in July, involving experts in porphyry and epithermal systems, to analyze the geological, geochemical, and alteration data. This collaboration is intended to enhance targeting strategies for subsequent drilling efforts.

The 2026 drilling program included two drill holes, totaling 2,173.7 meters. The first hole, TADD-278, reached 1,331.7 meters, while TADD-279 extended to 842 meters. The results obtained thus far suggest that drilling activities will resume in the next summer campaign, as the second hole has been cased to preserve the potential for continued exploration.

Broader Context of the Taguas Project

Orvana has expanded its evaluation of the Taguas Project beyond the previously outlined near-surface oxidized gold-silver resource from the 2021 Preliminary Economic Assessment. The team aims to include sulfide mineralization and potential copper-gold mineralization that lies beneath. An updated geological model and a conducted geophysical survey have also aided the identification of deeper targets.

The survey results, along with historical data reviews, have prioritized essential targets for initial drilling, which is vital for successful identification and further exploration of high-grade mineralization in the area.

El Valle-Boinás Brownfield Drilling Update

Shifting focus to Spain, Orvana also provided an update on its brownfield and infill drilling program at the El Valle–Boinás Mine in Asturias. The company completed 3,712 meters of drilling in Q3 of FY2026, concentrating on oxide mineralized bodies to validate inferred resources and potentially extend existing mineralization.

Conclusion

As Orvana continues its drilling campaigns, the promising assay results from Taguas coupled with detailed geological research and data analysis are expected to fuel further exploration success. With upcoming workshops and refined targeting strategies, the outlook remains positive for discovering additional mineral resources in both the Taguas Project and the El Valle-Boinás Mine. Stakeholders are keenly awaiting future assays results and further confirmations of this mineral potential.
