Orvana Minerals Corp. Reports Geophysical Survey Results and Commences Initial Deep Drilling Program At Taguas, Argentina
Orvana Minerals Corp. reported that the recently conducted Induced Polarization ("IP") and Magnetotelluric ("MT") geophysical survey at the Company's Taguas project located in the San Juan Province, Argentina ("Taguas" or the "Taguas Project") outlined a north-south-trending corridor characterized by elevated chargeability and a deep zone of moderate to low resistivity. These geophysical responses can, in some geological settings, be associated with sulfide-bearing systems. With the geophysical work complete, the Company has now begun its first deep drilling program at Taguas to find out whether these signals are related to a potential deep porphyry copper-gold system. Strategic Context. The Company repositioned 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 December 29, 2021, available at) to include the underlying sulfide mineralization and the potential deep porphyry copper -gold system. The Company completed an updated geological model for the Taguas Project and conducted a geophysical survey, designed to identify potential deeper targets to a depth of 1,500 metres. Results from the geophysical survey, combined with the recent review of historical exploration data have been used to prioritize key targets for the initial deep drilling, which is now underway. These mineralogical trends are spatially coincident with increasing Cu and Mo values at depth, the presence of early B-type quartz veinlets (indicate proximity to the high-temperature magmatic-hydrothermal core of a potential deep porphyry system), and favorable structural settings, collectively supporting the interpretation of a Magmatic-hydrothermal system at depth that warrants further evaluation through drilling. The integration of alteration vectoring, veining styles, and multielement geochemistry defines a robust exploration framework that is internally consistent across Cerro Campamento, Cerro III, and Cerro IV. While the frequency of deep drilling is limited, particularly at Cerro III, the convergence of SWIR-derived thermal gradients, Mo & Cu enrichment, and veinlets presence is considered encouraging in the context of the Company's exploration model. These results support further evaluation through targeted geophysical surveys and deeper drilling to validate and refine vectors toward a concealed porphyry intrusive center beneath the epithermal system. The geological modeling results described suggest a coherent exploration target at depth, which the Company is now testing through its initial deep drilling program. Geophysical Results. Ridgeback Geofisica Argentina S.A., an affiliate of Southernrock Geophysics was engaged by Orvana to conduct Magnetotelluric (MT) and Induced Polarization (IP) surveys across the southern portion of the Taguas property. In conclusion, the recent geophysical survey has identified significant subsurface features that align with geological models commonly used in the exploration of copper-gold porphyry systems. While these results do not confirm the presence of an economically viable mineral deposit, they have helped the Company better define target areas for deeper test drilling. Drilling commenced in January 2026, with a preliminary program of approximately 4,500 metres using one drill rig, which the company expects to complete by April 2026, subject to drilling conditions and logistics. Drill results from the program are expected to be released as they become available, subject to analysis and verification. In fiscal 2021, Orvana Argentina, S.A. engaged independent consultants, Mr. Joseph J. Kowalik, PhD., QP MMSA Senior Consulting Geologist, and Mr. Ronald G.Geo of Geosim Services Inc., to complete mineral resources estimate, which were published in the "Independent Technical Report NI 43- 101 on the Taguas Project, San Juan, Argentina," dated June 30, 2021, dated June 30, 2021. An updated mineral resource estimate for the Cerros Taguas deposit of the project was completed by Geosim Services in September 2022.
