Terra Balcanica drills 2.55 m of 102 g/t AgEq at Viogor

Executive Summary

• Terra Balcanica announced high‑grade silver‑equivalent intercepts from its Phase III drill program at the Cumavici Ridge epithermal vein zone, including 102 g/t AgEq over 2.55 m and a broader 64 g/t AgEq over 4.7 m.
• Additional holes returned notable grades such as 505 g/t AgEq over 11 m (CMVDD004) and 824.2 g/t AgEq over 4 m (CMVDD001), extending the known mineralized strike to ~95 m.
• The mineralization remains open both northwest along strike and downdip to the southwest, with further assay results pending release.

Key Details

• Hole CMV25001: 102 g/t AgEq over 2.55 m; broader zone of 64 g/t AgEq over 4.7 m from 66 m depth; includes a 0.4 m interval with 453 g/t AgEq.
• Strike Extension: Mineralized strike length now ~95 m (previously 73 m at CMV23004, which returned 1,168 g/t AgEq over 1.35 m).
• Other Highlight Intercepts:
• CMVDD004 – 505 g/t AgEq over 11 m.
• CMVDD001 – 824.2 g/t AgEq over 4 m.
• CMVDD005 – 284 g/t AgEq over 10 m (referencing prior releases).
• Geological Context: Fault‑hosted hydrothermal breccia intersected from 64–73 m depth; massive sulfide interval (0.4 m) with sphalerite, galena, stibnite, pyrite; mineralization associated with quartz‑calcite veining and breccia cement.
• System Extent: Mineralization confirmed on Cumavici Crest over ~500 m northwest; three polymetallic systems identified (Joseva, Cumavici Crest, Cumavici Ridge).
• QA/QC Procedures: Half PQ3 core samples processed at ALS Bor, Serbia and analyzed at ALS Loughrea, Ireland (ISO/IEC 17025:2017); sample prep PREP‑31BY; fire assay for Au with ICP‑AES finish; base metals digested via ASY‑ORE method; QC inserts at 9 % rate.
• Qualified Person: Dr. Aleksandar Miskovic, PGeo (NI 43‑101 QP).
• Advertising Note: Engaged Orsus Consult GmbH for three days of digital advertising in July 2025 – €25,000 (non‑material administrative detail).

Notable Quotes

“We are very pleased to have extended the footprint at the high‑grade Cumavici Ridge system by continuing to intercept the mineralized horizon… The epithermal, fault‑hosted mineralization was intercepted shallowly highlighting the potential of this southwest‑dipping structure, a high‑grade, close‑to‑surface silver‑ and base‑metal‑rich target.” – Dr. Aleksandar Miskovic, CEO

Materiality Assessment: Material – Positive (significant high‑grade assay results that materially expand the known resource envelope).
