ORVANA PROVIDES TAGUAS DRILLING UPDATE: FULL ASSAY RESULTS FROM TADD-278; SECOND HOLE RESULTS PENDING

Orvana Minerals Corp. has provided an update on its deep drilling campaign at the Taguas Project in San Juan, Argentina. Recent petrographic studies on core samples from the first drill hole, TADD-278, indicate that the mineralized host rock is a dacitic porphyry. The analysis revealed intense sericitic alteration dominated by quartz–sericite–pyrite, with mineralization that includes pyrite and associated enargite and/or chalcopyrite.

Complete laboratory results from TADD-278 highlight a 205-meter interval, ranging from 715 to 920 meters, with 0.25 g/t gold and 0.12% copper. The second drill hole, TADD-279, is expected to provide additional assay results and VNIR-SWIR measurements over the coming months, as the company prepares for its next drilling campaign scheduled for October 2026 to April 2027.

Raúl Álvarez, the Director of Exploration and Technical Services at Orvana, emphasized that ongoing studies continue to support the interpretation of a deep porphyry-related system at Taguas. The integration of various geochemical and geological data aims to refine targets for the next phase of drilling.

Orvana's exploration work at Taguas has expanded beyond a superficial focus on oxidized gold-silver resources to include deeper sulfide mineralization. An updated geological model and a geophysical survey have been conducted to identify potential targets at depths of up to 1,500 meters. With a total of 2,173.7 meters drilled across two holes in the FY2026 program, further drilling is anticipated once summer conditions return.

The company is also conducting quality assurance and control measures within its laboratory analyses to ensure accuracy and reliability in its results. This exploration update has been prepared under the supervision of a Qualified Person and aims to provide a clear understanding of the mineralization at the Taguas Project.
