Orvana expands Taguas project footprint via adjacent claims acquisition

ORVANA EXPANDS TAGUAS PROJECT FOOTPRINT THROUGH ACQUISITION OF ADJACENT CLAIMS PR Newswire TSX:ORV OTCQX: ORVMF #17-2026 TORONTO , June 29, 2026 /PRNewswire/ - Orvana Minerals Corp. (TSX: ORV) (OTCQX: ORVMF) (" Orvana " or the " Company ") is pleased to announce the strategic expansion of its land position at the Taguas Project, located in San Juan Province, Argentina, through the acquisition of the Evelina claims (the " Evelina Property ") from a subsidiary of Pan American Silver Corp. (NYSE: PAAS; TSX: PAAS), for total consideration of US$1,200,000 (the " Transaction "). Highlights The Evelina Property comprises four claims totalling 4,015 hectares, located in the Iglesia Department of San Juan Province, Argentina: Evelina I (Exp. No. 11240381-M-06), Gabriela 1 (Exp.

No. 0001-M-96), Gabriela 2 (Exp. No. 0002-M-96), and Gabriela 3 (Exp. No. 0003-M-96).

The addition of the Evelina Property increases the Taguas Project's exploration footprint by approximately 123%, from 3,274 to 7,289 hectares. The Evelina Property extends the Taguas Project along the same metallogenic belt, highlighting the potential continuity of a prospective epithermal corridor supported by early geological evidence. The Transaction provides opportunities to expand exploration activities at Taguas while increasing logistical optionality and flexibility for potential future infrastructure development.

Juan Gavidia, Chief Executive Officer of Orvana, commented: " As we advance our understanding of the porphyry system at depth at Taguas, we are expanding our land position and strengthening our presence in the district. The Evelina Property acquisition consolidates a continuous land package alongside Taguas, enhancing our geological optionality and increasing flexibility for potential future development. " Evelina Property The Evelina claims total 4,015 hectares and represent a strategic expansion withinthe same Oligocene–Miocene metallogenic belt that hosts the Cerros Taguas.

This addition enhances the Taguas Project's broader geological footprint and reinforces its district-scale exploration potential, particularly for epithermal gold and silver systems. Evelina East (see Figure 1) is interpreted as the potential southern extension of the Cerros Taguas mineralized corridor and constitutes the most advanced sector within the Evelina claims in terms of historical work. WordView-3 satellite imagery has outlined an epithermal system, consistent with the presence of a hydrothermal system.

This geological continuity increases confidence in the potential extension of mineralization beyond the current limits of the Taguas claims. Evelina West (see Figure 1), by contrast, remains underexplored but presents compelling early-stage indicators of a hydrothermal system. The presence of argillic alteration, with abundant alunite, is consistent with high-sulfidation epithermal environments.

The scale and intensity of alteration observed suggest the potential for a concealed mineralized system. Strategic Context The Company has expanded its evaluation of the Taguas Project beyond the near-surface oxidized gold-silver resource outlined in the 2021 Preliminary Economic Assessment (dated December 29, 2021, available at www.sedarplus.ca ) to include the underlying sulfide mineralization and potential porphyry-style copper-gold mineralization. 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.

The FY2026 program comprised 2 drill holes, totaling 2,173.7 metres drilled. First drill hole TADD-278 reached 1,331.7 metres and second TADD-279, 842 metres. Petrographic studies completed on drill core samples from hole TADD-278 indicate that the mineralized host rock corresponds to a dacitic porphyry.

The analyzed intervals display a well-developed porphyritic texture characterized by quartz, plagioclase and subordinate mafic phenocrysts set within a strongly silicified and sericitized groundmass, consistent with a hydrothermal porphyry system. The studies also identified intense sericitic alteration assemblages dominated by quartz-sericite-pyrite. Ore mineralization is primarily composed of pyrite with associated enargite and/or chalcopyrite, occurring as disseminations and veinlet fillings, further supporting the interpretation of a dacitic porphyry-related hydrothermal system.  Detailed information is available in the Company's news releases dated April 8, 2026 and May 27, 2026.

Results from drill hole TADD-279 remain pending and will be disclosed as additional data becomes available. Orvana considers the acquisition of the Evelina Property as part of its broader Taguas Project strategy, as the Company completes the interpretation of results from its FY2026 drilling campaign, continues the evaluation of historical data at Evelina, and advances the design of an integrated exploration program for FY2027. Transaction Details Pursuant to the Transaction, Orvana Argentina S.A., a wholly-owned subsidiary of the Company, acquired 100% of the interest in the claims comprising the Evelina Property from a subsidiary of Pan American Silver Corp. on an as-is, where-is basis, for total consideration of US$1,200,000.

The Transaction was completed on June 26, 2026, with customary registration formalities remaining.
