ORVANA PROVIDES TAGUAS DRILLING UPDATE: FULL ASSAY RESULTS FROM TADD-278; SECOND HOLE RESULTS PENDING
Orvana Drill Results Confirm Porphyry Potential Amidst Bolivia Operational Headwinds

Executive Summary
- The most recent release (May 27, 2026) provides full assay results from drill hole TADD-278 at the Taguas Project in Argentina.
- Key intercepts include a significant 205-metre interval containing 0.25 g/t gold and 0.12% copper.
- Petrographic studies confirm a dacitic porphyry-related system with intense sericitic alteration and pyrite mineralization associated with enargite and chalcopyrite.
- The FY2026 drilling program is concluded for the season (2,173.7 metres across two holes), with results from TADD-279 pending.
- Next steps include VNIR-SWIR Terraspec measurements, geochronological studies, and preparation for a new campaign in October 2026 – April 2027.
Material Impact
- The news confirms the geological hypothesis of a deep porphyry system at Taguas, which is positive for long-term valuation but does not immediately alter near-term cash flow projections.
- This update follows a significant operational setback announced on May 25 regarding civil unrest in Bolivia delaying Don Mario oxide ore processing (rated Material - Negative).
- While the exploration results are encouraging, they do not mitigate the immediate logistics and production delays at the primary revenue-generating asset (Don Mario).
- The drilling program was part of a planned FY2026 schedule; therefore, the confirmation is largely expected rather than a surprise discovery that changes project timelines.
- Given the recent stock price drop due to Bolivia unrest ($2.25 to $1.84), this news may provide some stabilization but lacks the materiality to reverse the operational risk sentiment immediately.
